Item 1. Business

We are a medical technology company specializingwith a mission to dramatically improve the cancer landscape with a modern solution for the early detection of multiple cancers thereby expanding the therapeutic window, significantly improving survivability, and reducing the cost of healthcare. One in predictivetwo Americans will be diagnosed with cancer during their lifetime and one in five will die. Clinical literature shows that early detection can save lives and money. We operate at the confluence of our Electrical Impedance Analytics (EIA) technology and artificial intelligence (AI). We are developing an advanced multi-cancer screening technology for early detection that may expand the therapeutic window, dramatically improve survivability and reduce the cost of healthcare. The first planned product utilizing our proprietary analytic early stageplatform, the IONIQ ProLung Test™ for lung cancer, risk testing,has been designated a Breakthrough Device by the U.S. FDA in February 2020, which we referincludes provisions for four years of CMS reimbursement.We remain fully committed to asgaining U.S. FDA regulatory de novo clearance and subsequently commercializing the “ProLungIONIQ ProLung Test^TM.” for lung cancer.

Our noninvasive,non-invasive, rapid and radiation-free IONIQ ProLung Test was developed to assess the risk of malignancy in lung nodules found in the chest by a Computed Tomography “CT” scan, which is currently the primary method used in the United States (“US”) for screening lung cancer. Lung cancer is the leading cause of cancer death in the US and the world according to American Cancer Society and World Health Organization. Earlier detection makes a substantial improvement in survival in individuals at high risk of lung cancer. Timely identification of malignancy is essential for patients and their families. Currently, patients often wait from three months to three and one-half years to have the risk of malignancy assessed through periodic CT scan surveillance. Until malignancy is determined to be likely, invasive biopsy and treatment are typically delayed. Current statistics reflect an average 17% survival rate at five years for those diagnosed with lung cancer.

We believe the IONIQ ProLung Test, in conjunction with the discovery of a nodule by CT scan, provides a more rapid assessment of the risk of malignancy, which must be determined prior to biopsy. Since a lung biopsy is invasive and may require life threatening thoracic surgery, physicians, patients, and insurance companies typically delay biopsy and therapy until the risk of malignancy outweighs the risk of further diagnostic procedures. For these patients, the delay can reduce the time available to treat the tumor and may cause sustained emotional trauma.

The IONIQ ProLung Test is designed to enable the practitioner to promptly assess the risk of malignancy in patients with lung nodules. The IONIQ ProLung Test utilizes mass-averaging bioconductive technology.technology or Electrical Impedance Analytics (EIA). Mass-averaging bioconductive technology involves a sequential scanning process that measures significant differences in electrical conductance between cancerous and benign tissue. We plan to introduce the IONIQ ProLung Test to the market as a standard predictive analytic test, without the need for transmission of a physical sample or specimen to a lab for analysis.

The IONIQ ProLung Test acquires bioconductance measurement data by means of a patented probe and disposable diaphoretic electrodes placed on the patient’s back and arms. The IONIQ ProLung Test registers and evaluates measurement data derived from numerous pathways through the chest and is processed by a predictive analytic algorithm. The results are summarized in a report that can be used by the physician, in concert with other risk factors such as nodule size, family history, smoking history and gender, to evaluate patients with nodules. The IONIQ ProLung Test requires minimal preparation and can be completed in fewer than 3020 minutes. Most importantly, it guides or informs the physician’s decision making without the time consuming, expensive and watchful waiting period. We believe the IONIQ ProLung Test provides considerable cost savings when compared with today’s status quo of patients undergoing repeated CT imaging studies and potentially unnecessary surgery.

ProLung dba IONIQ Sciences licensed and developed the intellectual property and established the clinical research plan for the IONIQ ProLung Test. Beginning in 2005, we embarked on clinical research which revealed the potential of our technology. In 2011, our research demonstrated the utility of the IONIQ ProLung Test in lung cancer patients. To date, more than 550 patients1,200 subjects have been tested using the IONIQ ProLung Test at IONIQ’s headquarters and in major cancer centers, such as MD Anderson, Loyola, UCLA, Stanfordcenters. If our de novo FDA clearance is granted, of which there can be no assurance, we plan to transition the hospitals that participated in our clinical trials to commercial placements of the IONIQ ProLung Test System and Huntsman Cancer Institute, among others.consumable IONIQ ProLunt Test kit.

In the US, the push for early detection of lung cancer was greatly accelerated in 2013.2013 and again most recenetly in 2020. Recognizing the dismal rate of lung cancer survival in the US, and the potential value of early detection, US guidelines were established for lung cancer CT screening. The guidelines provided for CT screening for lung cancer in asymptomatic adults aged 55 to 80 who have a 30 pack-year history of smoking and who currently smoke or have quit smoking in the past 15 years. This demographic group addresses a substantial portion of individuals of high risk of lung cancer. In 2020, the guidelines were expanded effectively doubling the population covered. The US health care industry has generally recognized the need for technologies that will provide for earlier detection of cancers at a lower cost. Genetic biomarkers, protein panels, and breath analysis, among others, are in various stages of development. The IONIQ ProLung Test is the first bioconductive technology that has been developed for the risk stratification of lung cancer. In February 2015, the US CenterCenters for Medicare and& Medicaid Services (CMS) announced its coverage of lung cancer screening by CT. This newly reimbursed screening procedure increased the number of individuals with suspicious lung nodules who may be candidates for the IONIQ ProLung Test.

With the arrival of lung cancer screening recommendations, the large US market and government-backed reimbursement represent near term opportunities to accelerate diagnosis and treatment of lung cancer while reducing invasive biopsies and costs. We made US clearance and recognition of the IONIQ ProLung Test our major priority, targeting lung cancer risk stratification and reducing time to treatment. We intend to seek government-backed reimbursement after FDA clearance. We are also interested in improving the cost of diagnosis and treatment with capitated providers. We believe the IONIQ ProLung Test can be offered at a fraction of the cost of current standard of care which is repeat periodic imaging studies.

In May 2013, we achieved an important validation of our IONIQ ProLung Test by receiving the “CE” mark in Europe. This certification verifies that the IONIQ ProLung Test meets the regulatory requirements for the marketing and sale of the IONIQ ProLung Test in the European Economic Area and European Free Trade Association Countries representing approximately 513 million individuals and 28-member states. Our European clinical research includes testing more than 154 patients in Italy, Switzerland and Germany. We intend to seek European reimbursement approval and accelerate our marketing in Europe following receipt of US Food and Drug Administration, (“FDA”) market clearance. We believe CT screening is likely to be implemented in Europe following the completion of several lung cancer screening trials already underway.

In September of 2013, we applied for marketing clearance under Section 510(k) from the FDA. After review of the 510(k) application, the FDA issued a letter to ProLung in May 2014 indicating that the FDA believed that our 510(k) would likely be found “Not Substantially Equivalent” to a legally marketed predicate device and the FDA believed ProLung may be suitable forde novo classification. Subsequently, we submitted ade novo petition in August of 2014. In February 2015, we received a “substantive review” from the FDA requesting additional information, regarding the risk classification of the test, the study design and study analysis. We held various meetings with the FDA and agreed to complete and include an additional clinical study which was already underway. Before the FDA can grant clearance of ourde novo application, we must resubmit the application with positive results from validation studies demonstrating efficacy and repeatability and resolve any remaining issues previously identified by the FDA as well as address possible issues that may be identified in the future. We are in the process of preparing the necessary information requested by the FDA.

We have developed the quality management system as well as supply chain and the ability to fully manufacture the entire ProLungIONIQ System in our own Salt Lake City facility. We have received ISO 13485 and other clearances and made certain refinements to the intellectual property that will further our capabilities, especially the development of the underlying predictive analytic algorithm and refinements to various software and physical components. Over the last five years, weWe have repatedly expanded our intellectual property portfolio, completed the development of the IONIQ ProLung Test and manufacturing of the ProLungIONIQ System and embarked upon clinical trials to provide validation to the medical community.

The preliminary results of the clinical trial of 420 patients from 15 cancer and medical centers across the US, named PL-208, was announcedpublished in early 2019. The results of another clinical trial of 486 patients from four cancer and medical centers in China, named PLW-216, was published in late 2019. We believe the results are an indicatormore solid indicators that our IONIQ ProLung Test is capable of identifying a signal that can be used to indicate therisk of malignancy in pulmonary nodules.nodules by non-invasively measuring their bioconductance biomarker. With the conclusion of this Study,these Studies, the ProLungIONIQ Team is eager to turn its focus to validating a number of already identified hardware, software training and data collection improvements designed to strengthen our algorithm’s performance and support a future submission to the FDA. The Company is also in the midst of evaluating a number of potential strategic partnerships to accelerate our development by expanding our financial and support network.

In late 2018, we announced final results of our Repeatability Study, named PL-209. The repeatability study enrolled sixty subjects, 30 male and 30 female, half of each gender with a body mass index (BMI) of 30 or more, and half with a BMI of 28 or less. Each subject was scanned twice on Day One and twice on Day Two. All scans were done by the same operator on the same ProLungIONIQ System. Fifty-nine subjects produced evaluable data. Four models (algorithms) were tested. The study was conducted by ProLung. Study objectives included quantifying the effects of gender, body mass index (BMI), day-to-day subject variability and variability of a single device when volume-averaged thoracic bioconductance was measured with the IONIQ ProLung Test.The repeatability study addressed several questions regarding use of the IONIQ ProLung Test. One significant limitation of this study is that no subjects with known pulmonary nodules or malignancy were enrolled. It is unknown whether pulmonary nodules or malignancy affect the repeatability of the IONIQ ProLung Test. While the study showed statistically significant variability of approximately 2% when testing the same subject twice on the same day, the clinical impact of this finding is unknown because it is not anticipated that patients will receive a second test on the same day in clinical use. While we note significant day-to-day variability when using an earlier model (the algorithm used in the Johns Hopkins Study,Journal of Thoracic Oncology, 2012), repeatability is markedly improved when using a more refined model.

In late 2019, we announced the final results of our Validation Study, named PLW-216. The validation study enrolled 486 subjects from four leading cancer and medical centers in China. The results were 84% sensitivity and 73% specificity in the 418 subjects included in the analysis.

In February 2020, the FDA designated the IONIQ ProLung Test a Breakthrough Device. Through the Breakthrough Device program, the FDA will provide ProLung with expedited reviews and the Centers for Medicare & Medicaid Services (CMS) has provisions for a simpler and faster pathway to reimbursement. This is not a marketing clearance.

PL-209 Study Conclusions

PL-208 Study (2012-2019)

Three Validation studies have been completed for the IONIQ ProLung Test. The first is PL-208 which enrolled 420 patients across 15 US centers (ID: NCT01566682). This study was two-phased, with a 200-patient open-labelled training set to test and optimize an algorithm, followed by testing of the optimized algorithm on the diagnosis-blinded 174-patient validation set. Forty-six (46) subjects (11%) were excluded for being lost to follow up or having an inconclusive diagnosis, missing or inadequate device data. The predictive algorithm utilized the patient’s bioconductance measurements coupled with the patient’s age and a binary cut-off point of 0.5 was chosen to distinguish between high and low likelihood of cancer. The algorithm was locked and applied to a blinded validation set of 174 patients and yielded a Sensitivity of 69% Specificity of 49%, Positive Predictive Value (PPV) of 70%, Negative Predictive Value (NPV) of 47% and overall Accuracy of 61%.

PLW-208 Study (2015-2016)

The second validation trial (PLW-208) was completed by the Company’s licensor (ProLung Wuxi). This study enrolled 138 subjects at 2 centers in China. This study was similar in design to the US PL-208 Study and obtained a Sensitivity of 77%, Specificity of 60%, PPV of 82%, NPV of 41% and an Accuracy of 73%. In reviewing this study, the Sponsor determined that test method and operator training needed to be improved to obtain better results.

PLW-216 Study (2017-2019)

Ultimately, the Study Sponsor (ProLung Wuxi) improved the device operator training, test method and device predictive algorithm. The Sponsor concluded the PLW-208 Study and initiated PLW-216, utilizing improved training, test method and a modified locked predictive algorithm. This PLW-216 Study was a single-phase validation study whereby the predictive algorithm was locked prior to the first patient being enrolled and the IONIQ ProLung Test results were provided to site investigators prior to knowing the subject’s actual diagnosis. The PLW-216 Study enrolled 486 subjects in China at 4 centers led by Dr. Bai, the Chair of the Chinese Alliance against lung Cancer and Director of the Shanghai Respiratory Research Institute (ID: NCT 02726633, registration No 20170226). The Validation Study demonstrated improved performance yielding a Sensitivity of 84% Specificity of 73%, Positive Predictive Value (PPV) of 78%, Negative Predictive Value (NPV) of 80% and overall Accuracy of 79% from the US Study PL-208 (ID NCT0156668). This performance is comparable to other diagnostic cancer devices such as Mammogram (~sensitivity of 75%, specificity of 71%) and was demonstrated in a large sample size of 418 subjects included in the final analysis.

PL-210 - ProLung Test Measurement Collection Protocols for Label Expansion (Ongoing NCT04134520)

The purpose of this Study is to identify and test different data collection methods to determine which approaches may be useful in evaluation additional cancers to lung cancer (including breast cancer) and improve the ProLung Testing procedure. Once this Study is complete, the Sponsor plans to evaluate these improvements in future follow up cancer validation studies that will assess device accuracy using the new measurement collection methods.

The Company was incorporated on November 19, 2004, as a Delaware corporation under the name of Hilltop Group Technologies Corp. In November 2006, the Company began operations and changed its name to Fresh Medical Laboratories, Inc., and in April 2017, the Company changed its name to ProLung, Inc. In May 2020, the Company filed a dba for IONIQ Sciences.

On November 15, 2006, the Company entered into an exclusive license agreement with BioMeridian Corporation (“BMC”). The license agreement allowed the Company to include the use of certain BMC technologies in the development of a medical device.

ProLung dba IONIQ Sciences is a clinical research company. Our expertise is managing lung cancer innovation. Our focus is to develop, market, and sell precision predictive analytical devices for a life-threatening disease. Our mission is to make a difference in time for underserved lung cancer patients.

If and when the Company has the required regulatory clearances, we plan to market, and sell the IONIQ ProLung Test in the US, European, Latin American, Chinese and other international markets.

Lung Cancer Market Summary

According to the American Cancer Society (“ACS”), lung cancer is the leading cause of cancer death among both men and women in the US; about one out of four cancer deaths in the US are from lung cancer. The ACS estimates that in 2017 more people in the United States will die of lung cancer than of colon, breast, and prostate cancers combined.

According to the World Health Organization (“WHO”), lung cancer is the most common cause of death from cancer worldwide and is estimated to be responsible for nearly one in five cancer related deaths. The overall ratio of mortality to incidence is 87%. Each year there are over 1.8 million new cases of lung cancer worldwide, as well as nearly 1.6 million deaths. The lifetime chance of developing lung cancer is 1:17 in women and 1:14 in men.

Until recently, asymptomatic lung cancer was detected only incidentally when looking for something else. Currently, a lung cancer screen now reimbursed by Medicare, is performed by low-dose computed tomography. This has led to a dramatic increase in number of individuals with lung nodules detected, which is intensifying the need for a risk stratification test such as the IONIQ ProLung Test. The following is a summary of the principal markets for the Company’s IONIQ ProLung Test.

Lung Cancer Incidence and Mortality

Lung cancer patients face median five-year survival rates of only 17% (compared to 89% for breast cancer and 98% for prostate cancer). Survival rates of lung cancer lags behind that of other cancer rates due to a lack of early and effective detection, and a challenging biopsy. A significant amount of time is required to assess the risk under current guidelines. Should innovation reduce the time required for assessing the risk of malignancy, lung cancer mortality could approach that of other cancer rates. In those instances when lung cancer was detected in its earliest stage, the five-year survival improves to 80% or approximately an improvement of five times.

U.S. Market

Americans at high risk:

Symptomatic:

Each year approximately 225,500 people are diagnosed with lung cancer. Approximatelycancer and approximately 90 percent of lung cancer patients are symptomatic at presentation.

Lung Cancer Screening:

Given the size of the US market and the progression of CT scan use in early detection, clearance and acceptance of the IONIQ ProLung Test in the US is the major priority. The CDC estimates that there are 94 million Americans at risk of lung cancer (which includes current and former smokers). In the National Lung Cancer Screening Trial of 53,454 patients, approximately 24% of the CT scans performed were positive revealing a lung nodule suspicious for lung cancer that required follow-up. CT screening was recommended by the US Preventive Services Task Force on December 31, 2013, and Medicare began to pay for lung cancer screening on February 5, 2016. Based on these estimates, if the approximately 94 million Americans at risk for lung cancer received a low dose CT screen approximately 24% (or 23 million) Americans may reveal lung nodules requiring follow up. We believe these patients would be eligible to receive the IONIQ ProLung Test.

In the US, 15 hospital groups participated in our clinical study (PL-208). If ourde novo FDA clearance is granted, of which there can be no assurance, we plan to transition these hospitals involved in research to commercial placements of the ProLung Test System and consumable test kit.

European Market

ProLung plans to utilize its CE mark in conjunction with US clearance in the European Union and European Free Trade Association Countries which represents approximately 513 million individuals and 28-member states. Europe has some of the highest smoking prevalence of any region in the world which has led to a high incidence of lung cancer. In 2012, the World Health Organization estimated that 268,000 individuals died from lung cancer and that more than 313,000 cases were diagnosed in the European Union.

It is estimated that 28% of Europeans smoke and approximately 133 million individuals are at high-risk of lung cancer. Applying the US rates in the published National Lung Screening Trial (2011), over 30 million of these individuals are estimated to have an indeterminate lung nodule and require follow-up to determine the risk of malignancy. As the number of individuals with indeterminate lung nodules continues to increase in Europe, risk stratification tools such as the IONIQ ProLung Test are needed to close the gap between discovery of a nodule and the determination of malignancy.

China Market

According to the World Health Organization, the number of smokers in China is steadily growing and increasing at higher rates than any other world region. One in three of the world’s cigarettes is smoked in China. The average Chinese smoker consumes 22 cigarettes per day. This is nearly a 50% increase from 1980. Overall, more cigarettes are smoked in China than in the next top 29 cigarette-consuming countries combined. Lung cancer is epidemic in China with 653,000 cases in 2012 and an estimated 597,000 deaths.

The government’s smoking cessation campaign and interventions are poorly funded and weakly enforced, and certain provincial governments are somewhat dependent upon state-owned tobacco sales and taxation. However, China’s Government is collaborating with pulmonology and radiology leadership to study low-dose CT screening for earlier detection of lung cancer. The government has also sponsored economic studies to investigate the reimbursement of lung cancer screening in the health insurance system.

As the number of individuals with indeterminate lung nodules continues to increase in China, risk stratification tools, such as the IONIQ ProLung Test will be needed to close the gap between discovery of a nodule and the determination of malignancy. This clinical need for risk stratification may be multiplied if a lung cancer screening program is implemented in the Chinese healthcare system.

Latin American Market – potential market of 25 million patients

Nearly 10% of the world’s smokers live in Latin America (i.e., more than 120 million). As yet, lung cancer screening is not widespread. As the number of individuals with indeterminate lung nodules increases in Latin America, another growing market will be available to the ProLung Test.

Latin America has an at-risk population for lung cancer of at least 120 million. In accordance with rates from the National Lung Screening Trial (2010), roughly 25 million individuals will have an indeterminate pulmonary lesion if screened and require follow up to determine the risk of malignancy. As the number of individuals with indeterminate lung nodules increases in Latin America, risk stratification tools, such as the ProLung Test, will be needed to close the gap between discovery of a nodule and the determination of malignancy.

Competition

The development and commercialization of new products to improve the accuracy and efficiency of risk stratification of lung cancer is competitive, and we expect considerable competition from major medical device companies, laboratory biomarker tests, and academic institutions that are conducting research in lung cancer. Extensive research and financial resources have been invested in the discovery and development of new lung cancer detection tests. Potential competing technologies include, but are not limited to, breath markers, sputum cytology, and DNA-related markers, blood markers, radiography and CT imaging.

The timing of market introduction of some of our potential products or of competitors’ products may be an important competitive factor. We believe the speed with which we can develop products, complete clinical trials and clearance processes, and supply commercial quantities to market are important competitive factors. We expect that competition among products approved for sale will be based on various factors including product efficacy, safety, reliability, availability, price, reimbursement, and patent position. We believe that our IONIQ ProLung Test is superior or equivalent to existing alternatives in all of these areas, other than availability (in the US due to lack of FDA clearance) and reimbursement.

Business

IONIQ ProLung Test

The IONIQ ProLung Test is comprised of the following two components:

ProLung’s novel mass-averaging bioconductiveElectrical Impedance Analtyics technology simultaneously considers data from multiple measurement pathways and utilizes a patented predictive analytic algorithm to combine the individual measurements into a weighted average composite score that indicates an increased or decreased risk of malignancy in the individual in which the nodule has been detected. No images are generated by the IONIQ ProLung Test and extensive training is not required to interpret the composite score.

If required regulatory clearances are received, the IONIQ ProLung Test will be introduced to the market as a standard predictive analytic test without the need for transmission of a physical sample or specimen. Instead, the IONIQ ProLung Test acquires bioconductive measurement data by means of a patented probe and disposable diaphoretic electrodes placed on the back and hands. The data containing precision measurements is processed by a patented predictive analytic algorithm and a report is generated that may be used by the physician in addition to other risk factors, such as nodule size, family history, smoking history, and gender to evaluate patients with suspicious masses or lesions identified by CT scan. The IONIQ ProLung Test is non-invasive, rapid and non-radiating. It requires minimal patient preparation and can be completed in fewer than 30 minutes.

The IONIQ ProLung Test Procedure

Research and Clinical Trial Results

Our IONIQ ProLung Test has been evaluated in fourseven clinical trials and concluded a fifthat 24 clinical trial in 2018.sites with 1,200 subjects generating more than 20,000,000 data points. We made modifications to the IONIQ ProLung Test throughout the research process and will continue to attempt to improve its performance. A description of each clinical trial is below:

MulticenterPL-208 Study of the ProLung Test aka PL-208 – Multicenter (2018)(2012-2019)

There were three Specific Aims of this study:

PLW-208 Study – (2015-2016)

FinalResults.PLW-216 Study – (2017-2019)

The primary purpose of this study was to demonstrate the accuracy or efficacy of the ProLung test by comparing the ProLung results to the actual patients' diagnoses. The study had two phases (stabilization and validation). The first phase was a stabilization phase, which was two hundred patients set aside to train and optimize a predictive algorithm. In the stabilization phase, a classifier algorithm was derived utilizing the ProLung measurements combined with the patients age. The stabilization phase classifier algorithm was locked and subsequently applied to 174 patients in a validation phase. In the validation phase the classifier algorithm obtained a sensitivity of 68%, a specificity of 49%, positive predictive value of 70%, negative predictive value of 47%, and an overall accuracy of 61%.

Safety Analysis – Adverse Events

The study also evaluated safety of the ProLung Test. Of the 420 patients enrolled in PL-208. There were no serious or unexpected adverse events. Among the 420 enrolled patients there were 3/175 adverse events. The first patient complained of chest wall pain at the measurement point location which resolved shortly after the test. The second patient indicated that the patient’s left pinky joint was hurt during the test. The pain resolved immediately upon completion of the test. The third patient experienced bruising at some measurement locations which was determined to be caused by a clotting disorder. This patient did not complain of any discomfort during the test. All patients who experienced an adverse event stated that they would agree to undergo measurement again. Two of the three adverse events came from patients from the same device operator. The Company suspected that the Operator may be pushing too hard during device measurement. This Operator was re-trained and no additional adverse events were reported.

We believe the PL-208 results are an indicator that the ProLung Test is capable of identifying a signal that can be used to indicate therisk of malignancy in pulmonary nodules. With the conclusion of this Study, the ProLung Team has learned of improved measurement collection techniques and improved operator training that we believe may improve future performance. The Company is eager to turn its focus to validating a number of these already identified improvements including; training, data collection, software and hardware which are designed to strengthen the ProLung test performance and support a future submission to the FDA. The Company is also in the midst of evaluating a number of potential strategic partnerships to accelerate development.

Other Research

PL-210 - ProLung Test Measurement Collection Protocols for Label Expansion (Ongoing NCT04134520)

The purpose of this Study is to identify and test different data collection methods to determine which approaches may be useful in evaluation additional cancers to lung cancer (including breast cancer) and improve the ProLung Testing procedure. Once this Study is complete, the Sponsor plans to evaluate these improvements in future follow up cancer validation studies that will assess device accuracy using the new measurement collection methods.

Mexico.In 2011, ProLung supported a study with a hospital located in Mexico City. The study was administered by ProLung’s partner who was pursuing a joint venture license for the Mexico territory. The partner eventually abandoned the study. After receiving preliminary test results, ProLung had reason to question the quality of the data being gathered and withdrew its support of the study.

China.We issued a license to an entity conducting research in China in 2013. This Chinese researcher has independently changed the measurement collection methodology and classifier algorithm of the device. Preliminary results of research in China have been presented at the 2017 American Thoracic Society International Conference Poster Session. Our licensee is currently conducting a 450Their 486 patient Validation Study in China using the ProLung technology with the modified measurement collection methodology and modified classifier algorithm. The study is expected to complete recruitmentalgorithm was completed in 2019. Preliminary results of the completed research in China have been presented at the 2017 American Thoracic Society International Conference Poster Session, as well as the 2019 International Symposium on Respiratory Diseases (ISRD) & American Thoracic Society (ATS) Joint Medical Conference.

In January 2019, ProLung amended the ProLung China license. The Amendmentsecond addendum extends the exclusivity of our licensees’ license and allows ProLung to pursue a US FDA pre-submission review using the licensee’s Chinese clinical Protocol. The purpose of the US FDA pre-submission is to obtain the FDA’s feedback regarding the use of Chinese clinical data to demonstrate safety and efficacy for US FDA marketing clearance. ProLung may use the Chinese study data to support its US FDA application if it follows Good Clinical Practice, compliant with FDA regulations and is applicable to the US Population. The FDA recommends a pre-submission when seeking approval solely on foreign data. However, we believe it is likely FDA will require a smaller US Study replicating China results and showing repeatability. (Guidance for Industry and FDA Staff: FDA Acceptance of Foreign Clinical Studies Not Conducted Under IND Frequently Asked Studies, 21 CFR 314.106, 21 CFR 312.120).

In August 2019, ProLung announced that it amended the ProLung China license. The third addendum supports an expanded full collaboration business relationship wherein Prolung China Co. (“Prolung China”) and subsidiary (ProLung Biotech Wuxi) agree to provide all ProLung Biotech Wuxi Know-How and Improvements and clinical data which are used in Clinical Trials in China (PLW-208 and PLW-216) to ProLung, and other matters

Italy and Switzerland. Four centers in Italy and one center in Switzerland conducted research with the IONIQ ProLung Test under the direction of local clinicians. At three of these sites, the research was part of a sales evaluation program for potential sale of the IONIQ ProLung Test. Subject enrollment at these sites did not conform to research protocols utilized by ProLung. Consequently, the data generated by these clinics were not published by the Company.

At two other sites, Geneva and Florence, additional physician-sponsored research was conducted. It is not known whether these sites conducted research with the IONIQ ProLung Test that was compliant with Good Clinical Practice or whether these patients conformed with the IONIQ ProLung Test patient selection criteria. However, in June 2017, at the World Congress of Thoracic Imaging the Geneva site posted results indicating Test sensitivity of 66% and a specificity of 66%. The positive predictive value was 94% and negative predictive value was 20%. Geneva researchers concluded the IONIQ ProLung Test could lower the need for invasive biopsies, especially in high risk patients. The small number of patients (n=27) precludes definitive conclusions.

Similarly, at a center in Florence, Italy, a study looked at 22 subjects undergoing the IONIQ ProLung Test and PET CT scans. They reported a sensitivity of 75% and a specificity of 50%, with a positive predictive value of 94% and a negative predictive value of 17%. Researchers concluded that the high positive predictive value of the IONIQ ProLung Test suggested utility in the evaluation of solitary pulmonary nodules, adding that further research was warranted. This was presented in the form of a poster at the 2017 American Thoracic Society Conference.

In addition, pursuant to the BMC License, we have licensed from BMC the rights to the technology that controls the functionality of the probe.

Governmental Regulations

Our business is subject to extensive federal, state, local and foreign laws and regulations, including those relating to the protection of the environment, health and safety. Some of the pertinent laws have not been definitively interpreted by the regulatory authorities or the courts, and their provisions are open to a variety of subjective interpretations. In addition, these laws and their interpretations are subject to change, or new laws may be enacted.

Both federal and state governmental agencies continue to subject the healthcare industry to intense regulatory scrutiny, including heightened civil and criminal enforcement efforts. We believe that we have structured our business operations and relationships with our customers to comply with all applicable legal requirements. However, it is possible that governmental entities or other third parties could interpret these laws differently and assert otherwise. We discuss below the statutes and regulations most relevant to our business.

US Food and Drug Administration regulation of medical devices.

The Federal Food, Drug and Cosmetic Act (the “FDCA”) and FDA regulations establish a comprehensive system for the regulation of medical devices intended for human use. Our products include medical devices that are subject to these, as well as other federal, state, local and foreign, laws and regulations. The FDA is responsible for enforcing most of the federal laws and regulations governing medical devices in the United States.

The FDA classifies medical devices into one of three classes - Class I, Class II, or Class III depending on their level of risk and the types of controls that are necessary to ensure device safety and effectiveness. The class assignment is a factor in determining the type of premarket submission or application, if any, that will be required before marketing in the United States. We currently anticipate that the ProLungIONIQ System will be classified as a Class IIde novo medical device.

Unless it is exempt from premarket review requirements, a medical device must receive marketing authorization from the FDA prior to being commercially marketed, distributed or sold in the United States. The most common pathways for obtaining marketing authorization are 510(k) clearance and PMA.

510(k) pathway

The 510(k)-review process compares a new device to a legally marketed device. Through the 510(k) process, the FDA determines whether a new medical device is “substantially equivalent” to a legally marketed device (i.e., predicate device) that is not subject to PMA requirements. “Substantial equivalence” means that the proposed device has the same intended use as the predicate device, and either the same or similar technological characteristics as the predicate device, or if there are differences in technological characteristics, the differences do not raise different questions of safety and effectiveness as compared to the predicate, and the information submitted in the 510(k) demonstrates that the proposed device is as safe and effective as the predicate device.

To obtain 510(k) clearance, a company must submit a 510(k)-application containing sufficient information and data to demonstrate that its proposed device is substantially equivalent to a legally marketed predicate device. These data generally include non-clinical performance testing (e.g., software validation, animal testing, electrical safety testing), but clinical data may also be required. Typically, it takes six to twelve months for the FDA to complete its review of a 510(k) submission; however, it can take significantly longer and clearance is never assured. During its review of a 510(k), the FDA may request additional information, including clinical data, which may significantly prolong the review process. After completing its review of a 510(k), the FDA may issue an order, in the form of a letter, that finds the device to be either (1) substantially equivalent and states that the device can be marketed in the United States, or (2) not substantially equivalent and states that device cannot be marketed in the United States. Depending upon the reason(s) for the not substantially equivalent finding, the device may need to be approved through the PMA pathway (discussed below) prior to commercialization.

After a device receives 510(k) clearance, any modification that could significantly affect the safety or effectiveness of the device, or that would constitute a major change in its intended use, including significant modifications to any products or procedures, requires a new submission and clearance of a new 510(k). The FDA relies on each manufacturer to make and document its determination that a new 510(k) is (or is not) required, but the FDA can review any such decision and can disagree with a manufacturer’s determination. If we are granted an initial 510(k), we may make minor product enhancements that we believe do not require new 510(k) clearance. If the FDA disagrees with our determination regarding whether a new 510(k) clearance was required for these modifications, we may need to cease marketing and/or recall the modified device. The FDA may also subject us to other enforcement actions, including, but not limited to, issuing a warning letter or untitled letter to us, seizing our products, imposing civil penalties, or initiating criminal prosecution.

De novo pathway

If, at the end of the FDA review of a 510(k), the FDA determines that a device is “Not Substantially Equivalent” (“NSE”) due to the unavailability of a predicate device, a new intended use or different technological characteristics that raise different questions of safety and effectiveness, the FDA may indicate that the device may be suitable for review under thede novo classification process. If the FDA believes general controls or general and special controls may provide reasonable assurance of safety and effectiveness, the FDA may indicate in the NSE letter that the product may be appropriate for thede novo classification process under section 513(f)(2) of the Federal Food Drug and Cosmetic Act (“FD&C Act”). Inclusion of this language within an NSE letter does not indicate that sufficient information currently exists to support a successfulde novo request, but simply indicates that given the risk profile of the device, it seems reasonable thatde novo classification may be appropriate.

Alternatively, if a manufacturer believes their device is appropriate for classification into Class I or Class II and has determined, based on currently available information, there is no legally-marketed predicate device, they may submit ade novo request without a preceding 510(k) and NSE.

Once ade novo request is received (regardless of whether it is preceded by a 510(k) and NSE determination), the FDA will also check that the content of thede novo request includes the information required by section 513(f)(2) of the FD&C Act.De novo requests that lack information to determine whether a potential predicate device exists may be placed on hold. If thede novo request is missing information and/or data necessary to determine whether general controls or general and special controls can provide reasonable assurance of safety and effectiveness, the FDA may issue an additional information (AI) letter or request information via interactive review. If thede novo requestor fails to provide a complete response within 180 calendar days of the date of the AI request, the FDA will consider thede novo request to be withdrawn. If ade novo request is withdrawn due to failure to submit adequate information, a newde novo request is required in order to reinitiate review of the device under thede novo classification process.

If the data and information submitted demonstrate that general controls or general and special controls are adequate to provide reasonable assurance of safety and effectiveness, the FDA will grant thede novo request. If ade novo request is granted, the FDA will issue you a written order granting thede novo request and identifying the classification of the device (either class I or class II). For class II devices, the FDA will also identify the applicable special controls. Effective on the date of the granting order, the requester may immediately begin marketing the device subject to the general controls and any identified special controls. The device may be used as a predicate device for future 510(k) submissions as appropriate.

Premarket approval pathway

Unlike the comparative standard of the 510(k) pathway, the PMA approval process requires an independent demonstration of the safety and effectiveness of a device. PMA is the most stringent type of device marketing application required by the FDA. PMA approval is based on a determination by the FDA that the PMA contains sufficient valid scientific evidence to ensure that the device is safe and effective for its intended use(s). A PMA application generally includes extensive information about the device including the results of clinical testing conducted on the device and a detailed description of the manufacturing process.

After a PMA application is accepted for review, the FDA begins an in-depth review of the submitted information. FDA regulations provide 180 days to review the PMA and make a determination; however, the review time is normally longer (e.g., 1-3 years). During this review period, the FDA may request additional information or clarification of information already provided. Also, during the review period, an advisory panel of experts from outside the FDA may be convened to review and evaluate the data supporting the application and provide recommendations to the FDA as to whether the data provide a reasonable assurance that the device is safe and effective for its intended use. In addition, the FDA generally will conduct a preapproval inspection of the applicant’s establishment to ensure compliance with the Quality System Regulation (“QSR”), which governs the methods used in, and the facilities and controls used for, the design, manufacture, packaging, labeling, storage, installation, and servicing of finished devices.

Based on its review, the FDA may (1) issue an order approving the PMA, (2) issue a letter stating the PMA is “approvable” (e.g., minor additional information is needed), (3) issue a letter stating the PMA is “not approvable,” or (4) issue an order denying PMA. A company may not market a device subject to PMA review until the FDA issues an order approving the PMA. As part of a PMA approval (or 510(k) clearance), the FDA may impose post-approval conditions intended to ensure the continued safety and effectiveness of the device including, among other things, restrictions on labeling, promotion, sale and distribution, and requiring the collection of additional clinical data. Failure to comply with the conditions of approval (or clearance) can result in materially adverse enforcement action, including withdrawal of the approval (or clearance).

Most modifications to a PMA approved device, including changes to the design, labeling, or manufacturing process, require prior approval before being implemented. Prior approval is obtained through submission of a PMA supplement. The type of information required to support a PMA supplement and the FDA’s time for review of a PMA supplement vary depending on the nature of the modification.

Clinical trials

FDA generally prohibits the shipping and marketing of medical devices in the absence of a premarket clearance or approval (where required). However, the FDA’s Investigational Device Exemption (“IDE”) regulation exempts the provision of devices for use in certain types of clinical trials – i.e., clinical trials to collect safety and effectiveness data for investigational devices, and clinical trials evaluating new intended uses and/or certain modifications to a legally marketed device – from this prohibition. This regulation places significant responsibility on the sponsor of the clinical study including, but not limited to, choosing qualified investigators, monitoring the trial, submitting required reports, maintaining required records, and assuring investigators obtain informed consent, comply with the study protocol, control the disposition of the investigational device, submit required reports, etc.

Clinical trials of significant risk devices (e.g., implants, devices used in supporting or sustaining human life, devices of substantial importance in diagnosing, curing, mitigating or treating disease, or otherwise preventing impairment of human health, or that otherwise present a serious risk to the health, safety, and welfare of a subject) require FDA and Institutional Review Board (“IRB”) approval prior to starting the trial. FDA approval is requested through submission of an IDE application. Clinical trials of non-significant risk (“NSR”), devices (i.e. devices that do not meet the regulatory definition of a significant risk device) do not require FDA approval but do require IRB approval before starting. The clinical trial sponsor is responsible for making the initial determination of whether a clinical study is significant risk or NSR; however, a reviewing IRB and/or FDA may review this decision and disagree with the determination.

An IDE application must be supported by appropriate data, such as nonclinical performance data, animal and laboratory testing results, showing that it is safe to evaluate the device in humans and that the clinical study protocol is scientifically sound. There is no assurance that submission of an IDE will result in the ability to commence clinical trials. Additionally, after a trial begins, the FDA may place a clinical trial on hold or terminate it if, among other reasons, it concludes that the clinical subjects are exposed to an unacceptable health risk.

As noted above, the FDA may require a company to collect clinical data on a device in the post market setting.

The collection of such data may be required as a condition of PMA approval. The FDA also has the authority to order, via a letter, a post market surveillance study for certain devices at any time after they have been cleared or approved.

Pervasive and continuing FDA regulation

After a device is placed on the market, regardless of its classification or premarket pathway, numerous additional FDA requirements generally apply. These include, but are not limited to:

The FDA enforces these requirements by inspection and market surveillance. Failure to comply with applicable regulatory requirements can result in enforcement action by the FDA, which may include, but is not limited to, the following sanctions:

We are subject to unannounced device inspections by the FDA, as well as other regulatory agencies overseeing the implementation of and compliance with applicable state public health regulations. These inspections may include our suppliers’ facilities.

Marketing Approvals Outside the United States

Sales of medical devices outside the United States are subject to foreign government regulations, which vary substantially from country to country. The time required to obtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ.

Europe

Under the European Union Medical Device Directive, or EU MDD, medical devices must meet the EU MDD requirements and receive a CE marking certification prior to marketing in the European Union, or EU, which we received for the IONIQ ProLung Test in May 2013. CE marking is the uniform labeling system of products designed to facilitate the supervision and control of the EU concerning manufacturers’ compliance with the various regulations and directives of the EU and to clarify the obligations imposed in the various legislative provisions in the EU. Use of a uniform product labeling indicates compliance with all the directives and regulations required for the application of such labeling, and it is effective as a manufacturer’s declaration that the product meets the required criteria and technical specifications of the relevant authorities such as health, safety, and environmental protection. CE marking ensures free trade between the EU and European Free Trade Association countries (Switzerland, Iceland, Liechtenstein, and Norway) and permits the enforcement and customs authorities in European countries not to allow the marketing of similar products that do not bear the CE marking sign. Such certification allows, among other things, marking the products (according to various categories) with the CE marking and their sale and marketing in the EU.

CE marking certification requires a comprehensive quality system program, comprehensive technical documentation and data on the product, which are then reviewed by a Notified Body, or NB. An NB is an organization designated by the national governments of the EU member states to make independent judgments about whether a product complies with the EU MDD requirements and to grant the CE marking if we, and our product, comply with specified terms. After receiving the CE marking, we must pass a review carried out by the competent NB annually, under which it audits our facilities to verify our compliance with the ISO 13485 quality system standard.

Compliance with the ISO 13485 standard, for medical device quality management systems, is required for regulatory purposes. ISO standards are recognized international quality standards that are designed to ensure that we develop and manufacture quality medical devices. Other countries are also instituting regulations regarding medical devices. Compliance with these regulations requires extensive documentation and clinical reports for all our product candidates, revisions to labeling, and other requirements such as facility inspections to comply with the registration requirements.

China

China’s medical device market, currently in a rapid state of expansion, is overseen by the China Food and Drug Administration, or CFDA (formerly the State Food and Drug Administration). The CFDA issues registration certificates required for all medical devices sold in China. The CFDA uses a risk-based system, and its approval process requires mandatory testing for Class II and III devices. Class II devices are moderate-risk devices and Class III devices are high-risk medical devices. Third-party review of devices is currently not allowed in China; only the CFDA is authorized to approve devices. The registration process requires the submission of a registration standard along with device samples for testing. Manufacturers of Class II and Class III medical devices are also required to demonstrate that the device has been approved by the country of origin with documents like a CE certificate, 510(k) letter and PMA approval and compliance with ISO 13485, and they may also be required to submit clinical data in support of their application. In addition to these requirements, all medical device manufacturers must also include product information in Chinese on all packaging and labeling. Manufacturers exporting medical devices to China must appoint several China-based agents to act on their behalf. These include a registration agent to coordinate the CFDA registration process, a legal agent to handle any adverse events reported with a registered device, including a product recall, and an after-sales agent to provide technical service and maintenance support.

Other Healthcare Laws and Compliance Requirements

In the United States, our activities are potentially subject to regulation by various federal, state and local authorities in addition to the FDA, including the CMS, other divisions of the United States Department of Health and Human Services (e.g., the Office of Inspector General), the United States Department of Justice and individual United States Attorney offices within the Department of Justice, and state and local governments. These regulations include:

In addition, we may be subject to data privacy and security regulation by both the federal government and the states in which we conduct our business. The Health Insurance Portability and Accountability Act, or HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, or HITECH, and its implementing regulations, imposes certain requirements relating to the privacy, security and transmission of protected health information. Among other things, HITECH makes HIPAA’s privacy and security standards directly applicable to “business associates”—independent contractors or agents of covered entities that receive or obtain protected health information in connection with providing a service on behalf of a covered entity. HITECH also created four new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates and possibly other persons, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions. In addition, state laws govern the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts.

Post-Marketing Regulations

Following approval of a new product, a company and the approved product are subject to continuing regulation by the FDA and other federal and state regulatory authorities, including, among other things, monitoring and recordkeeping activities, reporting to applicable regulatory authorities of adverse experiences with the product, providing the regulatory authorities with updated safety and efficacy information, product sampling and distribution requirements, and complying with promotion and advertising requirements, which include, among others, standards for direct-to-consumer advertising, restrictions on promoting for uses or in patient populations not described in the product’s approved labeling (known as “off-label use”), limitations on industry-sponsored scientific and educational activities, and requirements for promotional activities involving the internet. Although physicians may prescribe legally available products for off-label uses, manufacturers may not market or promote such off label uses. Modifications or enhancements to the products or labeling or changes of site of manufacture are often subject to the approval of the FDA and other regulators, which may or may not be received or may result in a lengthy review process.

Other Regulatory Matters

Manufacturing, sales, promotion and other activities following product approval are also subject to regulation by numerous regulatory authorities in addition to the FDA, including, in the United States, CMS, other divisions of the Department of Health and Human Services, the Consumer Product Safety Commission, the Federal Trade Commission, the Occupational Safety & Health Administration, the Environmental Protection Agency, and state and local governments. Sales, marketing and scientific/educational programs must also comply with federal and state fraud and abuse laws. If products are made available to authorized users of the Federal Supply Schedule of the General Services Administration, additional laws and requirements apply. Manufacturing, sales, promotion and other activities are also potentially subject to federal and state consumer protection and unfair competition laws.

The distribution of medical device products is subject to additional requirements and regulations, including extensive record-keeping, licensing, storage and security requirements intended to prevent the unauthorized sale of medical device products.

Our Marketing Process

We must receive separate regulatory approvals from the FDA and equivalent regulatory bodies in other countries for each of the devices before we can sell them commercially in the US or internationally. We cannot make the claims necessary to market any of our product candidates until we have completed the requirements for regulatory authorization. We do not know whether regulatory authorities will grant authorization for any of the products that we, our marketing partners, or distribution partners will develop.

A summary of the status of our marketing authorizations in the key initial markets we have identified is set forth below:

In 2018, we pursued a pre-submission process with the FDA to get their input and buy-in on our proposed statistical analysis for the PL-208 Study. The FDA suggested that we change the endpoint of our study from relative risk to positive predictive value (PPV) and negative predictive value (NPV). FDA also had other statistical and clinical questions, concerns and recommendations.

In January 2019, ProLung amended the ProLung China license. The Amendment extends the exclusivity of our licensees’ license and allows ProLung to pursue a US FDA pre-submission review using the licensee’s Chinese clinical Protocol. The purpose of the US FDA pre-submission is to obtain the FDA’s feedback regarding the use of Chinese clinical data to demonstrate safety and efficacy for US FDA marketing clearance. ProLung may use the Chinese study data to support its US FDA application if it follows Good Clinical Practice, compliant with FDA regulations and is applicable to the US Population. The FDA recommends a pre-submission when seeking approval solely on foreign data. However, we believe it is likely FDA will require a smaller US Study replicating China results and showing repeatability. (Guidance for Industry and FDA Staff: FDA Acceptance of Foreign Clinical Studies Not Conducted Under IND Frequently Asked Studies, 21 CFR 314.106, 21 CFR 312.120).

Before the FDA can grant clearance of ourde novo application, we must resubmit the application with the results from the validation and repeatability studies and resolve or negotiate any existing and new issues identified by the FDA. We are hopeful regarding the resolution of any such issues. As a result of the face-to-face July 16, 2015 meeting

In February 2020, the FDA designated the IONIQ ProLung Test a Breakthrough Device. Through the Breakthrough Device program, the FDA will provide ProLung with expedited reviews and the Centers for Medicare Medicaid Services (CMS) has provisions for a simpler and faster pathway to reimbursement. This is not a marketing clearance. In 2020, we also received feedback from the FDA regarding the PLW-216 Study. The FDA has shared concerns regarding, indications for use, risks of the device, mechanism of action, device usability and repeatability, efficacy, PLW-216 Study design and applicability of the PLW-216 study results to the US population. Before the FDA can grant clearance of our de novo application, we must resubmit the application and resolve FDA’s questions and concerns. As a result of our meetings with the FDA, submission of a newde novo application and possible changes in the FDA review team make it impossible to predict when, or if, clearance might occur with certainty, nor can we be certain that clearance under thede novo pathway or any other pathway ultimately will be granted.   ● European Union.CE marking was granted as of May 10, 2013 for the IONIQ ProLung Test which permits the product to be sold throughout the European Economic Area (European Union member states plus Iceland, Liechtenstein and Norway), Switzerland, and Turkey. CE marking requires manufacturers to maintain an ISO 13485 Quality System.         ● Latin America.ProLung previously sponsored a pulmonary and lung cancer specific symposia in Latin America and developed relationships with key regional opinion leaders in lung cancer management. ProLung also discussed distribution and commercialization deals with distributors in Latin America. Based on primary physician feedback and response, ProLung expects a viable and strong market for a predictive analytic device such as the ProLung Test. ● China.The CFDA (previously known as the SFDA) roughly follows the FDA model and is the source of clearance for the marketing and sale of medical devices in China. To be sold in China, medical devices must be registered with Chinese health authorities. In February 2014, the Company’s licensor in China received clearance to manufacture the device from the Beijing government. Additional clearances are required to market and sell the device in this market.   After each respective regulatory clearance is obtained, the next step in each of these markets is for insurance companies or government agencies, as applicable, to agree to reimburse providers for the IONIQ ProLung Test. We have not commenced this process in the US or any other market, as we do not yet have marketing authorizations.   Manufacturing Requirements   As a manufacturer of medical devices, we must comply with the 21 CFR Part 820 Good Manufacturing Practice regulations established by the FDA. These requirements are meant to ensure that medical devices are safe and effective. We maintain a quality management system that includes standard operating procedures for key processes such as design, manufacturing, packaging, labeling, storage, installation, servicing, record keeping, complaint handling and corrective and preventative action. Our quality management system is currently ISO 13485 certified and is intended to meet the 21 CFR Part 820 Good Manufacturing Practice regulations. We will also be subject to similar requirements imposed by other countries.   Manufacturing   We currently manufacture the IONIQ ProLung Test and the IONIQ ProLung Test Kit. When volume requirements exceed current manufacturing capacity, we intend to utilize contract manufacturers for the physical manufacturing of our products. This may afford us numerous benefits, including:     ● the ability to ramp up production quickly;         ● access to leading technologies, supply chain networks and best-in-class manufacturing processes for its products;         ● flexibility to use one or many manufacturers in many regions of the world to optimize costs, production volumes, material availability, lead times, and to meet various regional regulations.   We have interviewed, performed site visits, and qualified multiple, redundant contract manufacturers which may be required to produce our products. We have no contractual obligations with such contract manufacturers for the manufacturing of our products. Our prospective contract manufacturers will source our product components from multiple specialized vendors that supply plastics, sheet metal, machining, cables, wire harnesses, and other computer hardware components. We maintain our own design control and ISO 13485 quality system.   Research and Development   The Company spent $2,036,792$2,099,463 and $1,630,837$2,036,792 on company-sponsored research and development during fiscal years ending December 31, 2019, and 2018, and 2017, respectively. 18   Employees   As of April 16, 2019,December 31, 2020, we had sixeight employees. As of April 30, 2021, we had eight employees.   Emerging Growth Company   We are an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”), and we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies” including, but not limited to, not being required to comply with the auditor attestation requirements of section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. We cannot predict if investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.   In addition, Section 107 of the JOBS Act also provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. In other words, an “emerging growth company” can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We are choosing to take advantage of the extended transition period for complying with new or revised accounting standards. As a result, our financial statements may not be comparable to those of companies that comply with public company effective dates.   As of December 31, 2020, we remain an “emerging growth Company. We believe we will remain an “emerging growth company” through at least December 31, 2019.2021.   Item 1A. Risk Factors   Our business, operations, and financial condition are subject to certain risks and uncertainties. Should one or more of these risks or uncertainties materialize, or should any underlying assumptions prove incorrect, our actual results will vary, and may vary materially, from those anticipated, estimated, projected, or expected. Among the key factors that may have a direct bearing on our business, operations or financial conditions are the factors identified below:   RISKS RELATED TO OUR STAGE OF DEVELOPMENT   We are a development stage company with limited revenue and no assurance of earning significant revenue over the long term.   We were organized in 2004 and since that date have experienced significant losses from operations. We are in the process of commercializing our proprietary IONIQ ProLung Test in the US and Europe and seeking marketing clearance for the IONIQ ProLung Test in the United States and expect to incur additional operating losses in the near term. We have generated limited revenue from the sale of our products and services. The amount of losses we will incur, and whether we will become profitable at all, are highly uncertain. Our net loss for the year ended December 31, 20172020 was $5,369,312$2,727,616 and for the year ended December 31, 20182019 was $7,709,282. $4,619,887. Our future success depends on our ability to begin generating revenues on a regular and continuing basis and to properly manage costs. Our ability to generate revenues depends on several factors, some of which are outside our control. These factors include our ability to obtain necessary government and regulatory marketing authorizations, our ability to successfully commercialize the IONIQ ProLung Test, our ability to protect intellectual property related to the IONIQ ProLung Test, our ability to obtain coverage and reimbursement for the test procedure from Medicare and other third- party payers, and our ability to effectively market our products. If we cannot expand our revenue significantly over the long term, we will not be profitable.   We are dependent upon financings to fund our operations and may be unable to continue as a going concern.   We do not generate sufficient cash flows from operations to meet the cash requirements of our operations and other commitments without raising funds through the sale of debt and/or equity securities. We do not expect to generate enough cash, if any, from operations to meet our requirements in the near term. Proceeds raised from funding activities, including the net proceeds from this offering, are required for us to have funds to meet our obligations for the foreseeable future. Our ability to continue as a going concern will depend, in large part, on our ability to obtain additional financing and generate positive cash flow from operations, neither of which is certain. If we are unable to achieve these goals, our business would be jeopardized and it may not be able to continue operations.   19 We will need significant capital to execute our business plan.   We currently generate no revenue, and we require at least $2.0 million in capital each year to operate our business. We also anticipate requiring additional capital to conduct additional clinical studies prior to submitting an application for FDA clearance for our IONIQ ProLung Test.Test, If we obtain FDA clearance, of which there is no assurance, we will need to obtain significant additional capital in order to roll outexecute our sales and marketing go-to-market plan.   As of December 31, 2018, we had a cash balance and pre-paid expenses totaling $273,539 and current liabilities of $507,353. We do not currently have any arrangements or credit facilities in place as a source of funds, and there can be no assurance that we will be able to raise sufficient additional capital on acceptable terms, or at all. We may seek additional capital through a combination of private and public equity offerings, debt financings and strategic collaborations. Debt financing, if obtained, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, could increase our expenses and require that our assets secure such debt. Moreover, any debt we incur must be repaid regardless of our operating results. Equity financing, if obtained, could result in dilution to our then existing stockholders. If such financing is not available on satisfactory terms, or at all, we may be required to delay, scale back or eliminate our testing and developing activities or, if we obtain FDA clearance, marketing efforts, which will harm our operations and financial condition, if we are unable to secure sufficient capital to fund our operations, we may have to discontinue operations and liquidate (and we anticipate that our liquidation value would be nominal).   We have issued significant indebtedness, and, if we are unable to repay or refinance it, our creditors could force us into bankruptcy.   As of December 31, 2018,2020, we had outstanding Notes of $4,189,681.and Loans totaling $7,948,929. The balances of our loan obligations are scheduled to come due in 2020 and 2022. If we default under our loan obligations, and we do not have sufficient cash resources to repay the loan, our creditors would have the ability to force us into bankruptcy. As a result of any bankruptcy proceeding, if cash resources were depleted, it is doubtful that there will be any amount available for distribution to our stockholders.   Risks Related to Our Business and Industry   We are in the early stages of commercialization and our IONIQ ProLung Test may never achieve commercial market acceptance.   Our IONIQ ProLung Test is approved and commercially available only in a limited number of countries and will not be available for sale in other countries, including the United States, until clinical development is completed and regulatory authorizations are obtained. Following ourde novoapplication for marketing clearance for the IONIQ ProLung Test from the FDA, in February 2015, we received a letter from the FDA identifying many issues, questions, and concerns in our submission, including issues regarding our proposed risk classification for the test, the study design and analysis plan for the clinical trial intended to support our submission, along with certain other questions. In subsequent communications and meetings with the FDA, we succeeded in addressing a number of the FDA’s concerns, and we were asked to complete a clinical study. In 2018, before breaking the study data blind and analyzing the amassed clinical data for our PL-208 study, we collaborated with the FDA through two formal Pre-Submission Meetings regarding our PL-208 Study Statistical Analysis Plan, study design, device output and statistical approaches. Furthermore, in 2020 we have received feedback from the FDA regarding the PLW-216 Study. The FDA has shared concerns regarding, indications for use, risks of the device, mechanism of action, device usability and repeatability, efficacy, PLW-216 Study design and applicability of the PLW-216 study results to the US population. We receivedhave ongoing meetings with the FDA to address these significant comments from the FDA some but not allmany of which have not yet been resolved. The FDA will likely require additional clinical study work and resolve or negotiate the removal of the remaining issues previously identifiedpreviouslyidentified by the FDA, as well as address issues to be identified in the future, before clearing the IONIQ ProLung Test for marketing. This may nevermaynever occur. Moreover, the successful commercialization of our product will require significant, time-consuming and costly sales and marketing efforts. If the commercialization of our IONIQ ProLung Test is unsuccessful or we are unable to market our IONIQ ProLung Test due to market developments, failure to obtain and maintain the regulatory authorizations necessary for our business to be commercially viable, development of alternative diagnostics or otherwise, we will be required to expend significant additional resources on research and developmentanddevelopment to improve our IONIQ ProLung Test. The development of a new test will be subject to the risks of failure inherent in the creation of any innovative new medical technology. These risks include the possibilities that our test will not be effective or of acceptable quality, will fail to receive necessary regulatory authorizations, will be uneconomical to manufacture or market or does not achieve broad marketbroadmarket acceptance, and that third parties market a superior or equivalent product. Even if our test is effective, it may not be accepted by patients or physicians. The failure of our research and development activities to result in any commercially viable products would have a material adverse effect on our business and financial condition.   20 We are reliant on a single product and if we are not successful in commercializing the IONIQ ProLung Test and are unable to develop additional products, our business will not succeed.   We have no experience commercializing the ProLung ScanIONIQ System and ProLung Test. In addition, we currently have one central product, ourIONIQ ProLung Test. We currently have no other productproducts available for sale. If the IONIQ ProLung Test isor our other products in development are not successful at a level sufficient to generate a profit and we are unable to develop additional products, our business will not succeed.   The ability to add to the product suite is subject to the availability of additional funds and certain factors not in our control, such as government policy. We may eventually want to expand the IONIQ ProLung Test to other cancer targets. ProLung does not have clinical data suggesting that the IONIQ ProLung Test is effective in other cancers and the IONIQ ProLung Test may not be effective in other cancers.   We are subject to litigation risk if our IONIQ ProLung Test is not effective.   The nature of the IONIQ ProLung Test as a medical technology platform and the general litigious environment of the market should be regarded as potential risks that could significantly and adversely affect our financial condition and results of operations in the future. If the IONIQ ProLung Test does not perform as demonstrated in well controlled clinical trials and as reviewed by the FDA, there could be significant, even life-threatening, adverse consequences. We may be subject to claims against us as a result of the failure of the IONIQ ProLung Test or other devices. We may also be subject to claims even though the injury is due to the actions of others, such as manufacturers or medical personnel. If we are sued, we may not have the resources to defend any such lawsuit or pay any related judgments. In addition, even the existence of a lawsuit will divert management’s attention from the development and commercialization of the IONIQ ProLung Test. Any insurance obtained by us may not adequately cover the amount or nature of any claim asserted against us and we are exposed to the risk that claims may be excluded from insurance coverage and that insurers may become insolvent. Moreover, there may not be any insurance available that would adequately cover all such risks. We are subject to litigation risk as result of recent our prior offering activities.   We recently experienced a very public proxy battle for control of the board of directors. In that process, both sides of the proxy battle made numerous allegations of wrongdoing by a former officer/directorofficers and directors of ProLung. The allegations have led to expressions of frustration and anger by existing shareholders, certain of which have threatened to file lawsuits against ProLung, its former executives and various current and former directors. Complaints by shareholders and former employees have also led to an investigation being opened by the Utah Division of Securities related to the Company’s and individuals’ activities. If any of the threats, allegations and investigations lead to legal actions against the Company or its current or former officers and directors, we will be significantly limited in our ability to raise capital and will be required to expend management time and financial resources on such legal actions. It is unlikely that we would be able to continue as a going concern following any such legal actions. On April 23, 2019, the Utah Division of Securities (the “Division”) filed a Notice of Agency Action and an Order to Show Cause before the Division of Securities of the Department of Commerce of the State of Utah against the Company, Jared Bauer and former Board Members (Clark Campbell, Tim Treu, Todd Morgan and Robert Raybould). In January 2020, the Division issued a Stipulation and Consent Order which set forth the following: 1) the Company agrees to settle the matter with the Division by way of the Stipulation and Consent Order; 2) the Stipulation and Consent Order fully resolves all claims the Division has against the Company pertaining to the Order to Show Cause; 3) the Division, ProLung and Bauer, agree to promptly file a stipulation and joint motion to dismiss ProLung and Bauer from this administrative action, with respect to Count 1 against ProLung and Bauer (the only claim brought against Bauer); 4) In or about April 2014, the Company Board of Directors circulated a consent agreement regarding the issuance of 582,102 (72,763 post-split) ProLung stock certificates to select members of the ProLung Board of Directors in connection with “financing services provided” by those members; 5) In or about April 2014, ProLung issued stock grants of 216,000 (27,000 post-split) shares to Robert W. Raybould, 16,350 (2,044 post-split) shares to Steve Eror, 63,750 (7,968 post-split) shares to Treu; 193,500 (24,118 post-split) shares to Campbell; and 97,500 (12,188 post-split) shares to Morgan; 6) Subsequent to issuance of those shares, ProLung was informed by counsel of potential consequences for Pro Lung employing unlicensed agents and individuals receiving the shares as compensation directly for sale of securities without a securities license, as opposed to receiving shares as compensation for generalized board service. Subsequently, no further shares were issued as compensation for fundraising. Mr. Eror returned his shares to the Company. However, Raybould, Treu, Campbell and Morgan did not return their shares to the Company. ProLung did not disclose the potential licensing violation until on or about December 3, 2018, in its Note Purchase Agreements. As set forth by the Company in its Form 8-K dated November 27, 2019, Campbell, Treu, Morgan, and Raybould entered into Stipulation and Consent Orders wherein they returned shares of stock to the Company’s treasury and paid fines to the Division of Securities. On January 9, 2020, the Division entered an order as follows: 1) entering certain Findings and Conclusions by the Division, which ProLung admitted via a Stipulation and Consent Order; 2) ordering ProLung to cease and desist from violating Utah Uniform Securities Act (the “Act”) and to comply with the requirements of the Act in all future business in the state of Utah; 3) ordering ProLung to disclose the contents of the order to investors and prospective investors in all future capital raising efforts and disclosure documents of ProLung; and 4) Ordering ProLung to pay a fine of $55,000 to the Division.   We may incur substantial product liability expenses due to manufacturing or design defects, or the use or misuse of our products.   Our business exposes us to potential liability risks that are inherent in the testing, manufacturing and marketing of medical products. We may face liability to our distributors and customers if our products are not manufactured as per specifications or if such specifications cause the products to become unsafe or fail to function as marketed or sold. We may also face substantial liability for damages if our products produce adverse side effects or defects are identified with any of our products that harm patients and other users. Any such failures or defects may lead to a breakdown in our relationships with distributors and purchasers leading to a substantial decline in or collapse of our market. In addition, if any judgments or liabilities are material in size, we may be unable to satisfy such liabilities. Any product liability could harm our operations and a large judgment could force us to discontinue our operations.   21 We are subject to the risk of product recalls if our products are defective.   The FDA and similar foreign governmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacture that could affect patient safety. In the case of the FDA, the authority to require a recall must be based on an FDA finding where there is a reasonable probability that the device would cause serious adverse health consequences or death. A government- mandated recall or voluntary recall by us or one of our distributors could occur as a result of component failures, manufacturing errors, design or labeling defects, or other issues. Recalls, which include corrections as well as removals, of any of our products would divert managerial and financial resources and could have an adverse effect on our financial condition, harm our reputation with customers, and reduce our ability to achieve expected revenues.   24 Lack of adequate third-party coverage and reimbursement for our customers could delay or limit the adoption of our products.   We may experience limited or no sales growth resulting from limitations on coverage and reimbursement for the diagnostic procedures performed with our products by third-party payors, and we cannot assure you that our sales will not be impeded and our business harmed if third-party payors fail to provide reimbursement for such procedures that customers view as adequate.   In the US, the IONIQ ProLung Test will be purchased primarily by medical institutions, which will perform the diagnostic procedure using our product and bill various third-party payors, such as Medicare and other government programs and private insurance plans, for the health care services provided to their patients. Acute care hospitals are generally reimbursed by Medicare for items and services provided to hospital inpatients under the Medicare hospital inpatient prospective payment system. Under the Medicare hospital inpatient prospective payment system, acute care hospitals receive a fixed payment amount for each covered hospitalized patient admission based upon the Diagnosis- Related Group (“DRG”) to which the inpatient stay is assigned, regardless of the actual cost of the services provided during that admission. If hospitals do not receive sufficient reimbursement from Medicare during an encounter in which our product is used, then a medical institution would have to absorb the cost of our products. At this time, we do not know the extent to which medical institutions would consider current Medicare inpatient payment levels adequate to cover the cost of our products, and we cannot assure you that such amounts are adequate. Failure by hospitals to receive an amount that they consider to be adequate reimbursement for the patient admissions during which our products are used could deter them from purchasing our products and limit our revenue growth. Moreover, DRG-based payments may decline over time, which could deter medical institutions from purchasing our products in the future. If medical institutions are unable to justify the costs of our products, they may refuse to purchase them, which would significantly harm our business.   Under current Medicare hospital inpatient reimbursement policies, the Centers for Medicare & Medicaid Services (“CMS”) offers a process whereby manufacturers may apply for temporary add-on payment for a new medical technology when the applicable DRG-based inpatient prospective payment rate is inadequate to cover the cost of a new product. To obtain add-on payment, a technology must be considered “new,” represent an advance in medical technology that substantially improves, relative to technologies previously available, the diagnosis or treatment of Medicare beneficiaries, and data reflecting the cost of the new technology must not yet be available in the data used to recalibrate the DRGs and the sponsor much show that admissions involving the furnishing of the technology exceed cost thresholds established by CMS for each applicable DRG. If an application is approved, “new technology” add-on payments are made to hospitals for no less than two years and no more than three years. Provisions exist for four years of automatic CMS reimbursement for Breakthrough Devices though the reimbursement landscape may change in ways the Company cannot predict. We must demonstrate the safety and effectiveness of our technology to the FDA in addition to CMS requirements before add- on payments can be made, and cannot assure you that CMS will agree to provide such incremental payments for the IONIQ ProLung Test. Even if the IONIQ ProLung Test receives FDA and other required regulatory clearances or approvals, the diagnostic procedure performed with the test may not receive incremental reimbursement in the foreseeable future, if at all. Moreover, many private payors look to Medicare in setting their reimbursement policies and amounts. If Medicare does not offer adequate reimbursement for the services offered using our products, this may affect reimbursement determinations by certain private payors.   The absence of, or limits on, reimbursements may affect our revenues and our ability to achieve profitability.   The cost of a significant portion of healthcare is funded by governmental, and other third-party, insurance programs. It is possible that our products will not be covered or adequately reimbursed by governments or insurance providers, which will seriously harm our ability to generate revenue. In addition, even if payers cover our products (or the services in which our products are used), limits on reimbursement imposed by such programs may adversely affect the ability of hospitals and others to purchase our products. In addition, limitations on reimbursement for procedures which utilize our products could adversely affect our business. If the IONIQ ProLung Test is not accepted by physicians and patients, we will be unable to achieve market acceptance.   Patients may be unwilling to depart from the current standard of care and opt not to undergo the IONIQ ProLung Test. In addition, physicians tend to be slow to change their medical treatment practices because of perceived liability risks arising from the use of new products. Physicians may not recommend or order the IONIQ ProLung Test until there is long-term clinical evidence to convince them to alter their existing patient management methods, there are recommendations from prominent physicians that the IONIQ ProLung Test is safe, effective, and clinically useful, and that reimbursement or insurance coverage is available. We cannot predict when, if ever, physicians and patients may adopt the use of the IONIQ ProLung Test. If the IONIQ ProLung Test does not achieve an adequate level of acceptance by patients, physicians and healthcare payors, we may not generate significant product revenue and we may not become profitable.   Accordingly, you should consider our prospects in light of the costs, uncertainties, delays and difficulties frequently encountered by early commercial stage companies. Potential investors should carefully consider the risks and uncertainties that a company with a limited operating history will face. In particular, potential investors should consider that we cannot assure you that we will be able to:     ● successfully execute our current business plan for the commercialization of the IONIQ ProLung Test, or that our business plan is sound;   ● successfully contract for and establish a commercial supply of components for the manufacture of the IONIQ ProLung Test and the ProLung Scan System;   ● achieve market acceptance of the IONIQ ProLung Test; and   ● attract and retain experienced personnel.   If we cannot successfully execute any one of the foregoing, our business may not succeed and your investment will be adversely affected.   We are a small company and may be unable to compete with larger or better-funded companies that promote competitive technologies.   There are a number of competitive technologies currently being developed as well as refinements being made to existing competitive technologies. Technologies being developed or obtaining limited commercialization for the same intended use as our test include, methylated DNA tests, micro RNA tests, panels of proteins and minimally invasive biopsy. These include the current standard of care for the indication to be claimed for the IONIQ ProLung Test; the use of serial chest CT views over a period often ranging from three months to three and one-half years. To the extent that any of these technologies or refinements result in products that successfully address some of the shortcomings of existing products, or result in quality products that are less expensive, safer or outperform existing tests and the IONIQ ProLung Test, future demand for the IONIQ ProLung Test may be reduced or eliminated.   The future market for our products is characterized by rapidly changing technology. Our future financial performance will, in part, be dependent on our ability to develop and manufacture new products or improvements to existing products on a cost-effective basis, to introduce them to the market on a timely basis, and to have them accepted by physicians. We may not be able to keep pace with technological change or to develop viable new products in a timely fashion. Factors that could delay the release of potential products or even cancellation of our plans to produce and market these new products could include delays in research and development, delays in securing future regulatory authorizations, or changes in the competitive landscape. Many competitors offer a range of products in areas other than those in which we propose to compete, which may make such competitors and their products more attractive to surgeons, hospitals, group purchasing organizations, and other potential customers. Many competitors also have significantly more financial resources than us. Competitive pricing pressures or the introduction of new products by competitors could have an adverse effect on our ability to establish market acceptance for the IONIQ ProLung Test. We cannot predict future markets for the IONIQ ProLung Test or other products, and we may not be able to shift production to other products in the event of a lack of market demand for the IONIQ ProLung Test, leading to an accompanying adverse effect on our profitability.   We are dependent upon contract manufacturers to safely and timely manufacture our products.   If we commercialize our IONIQ ProLung test,Test, we will need to establish arrangements with contract manufacturers to manufacture, package, label, and deliver our products. Our business will suffer if there are delays or difficulties in establishing relationships with manufacturers to manufacture, package, label, and deliver our products, or if the prices charged by such manufacturers are higher than anticipated. Moreover, contract manufacturers that we may use must adhere to current Good Manufacturing Practices, as required by FDA. If any such manufacturers fail to comply with FDA requirements, they may be unable to manufacture our products. In addition, such manufacturers may fail to manufacture our products in accordance with specifications or may fail to meet delivery timelines, which may cause problems in our customer or distributor relationships and potentially lead to defaults or an obligation to pay damages. If we are unable to obtain or retain third party manufacturing on commercially acceptable terms, we may not be able to commercialize our products as planned. Our dependence upon third parties for the manufacturing of our products may harm our ability to generate significant revenues or acceptable profit margins and our ability to develop and deliver such compliant products on a timely and competitive basis.   Any manufacturing problem or the loss of a contract manufacturer could be disruptive to our operations and result in lost sales. Additionally, we rely on third parties to supply the raw materials needed to manufacture our product. Any reliance on suppliers may involve several risks, including a potential inability to obtain critical materials and reduced control over production costs, delivery schedules, reliability and quality. Any unanticipated disruption to a future contract manufacturer caused by problems at suppliers could delay shipment of the IONIQ ProLung Test, increase our cost of goods sold and result in lost sales.    We are dependent upon third parties for marketing and other aspects of our business.   We have limited experience in sales, marketing and distribution of our products and are just beginning the process of developing a sales and marketing organization, which includes an establishment of a distributor network. Our lack of experience could negatively impact our ability to enter into or maintain collaborative arrangements or other third-party relationships which are important to the successful commercialization of our products and potential profitability. We may be unable to establish or maintain adequate sales and distribution capabilities.   In developing a preliminary commercialization plan, much of our strategy for the commercialization of the IONIQ ProLung Test will also rely on us entering into various arrangements with licensors, distributors, and other third parties. We have entered into an exclusive license agreement with BioMeridian Corporation to use technology owned by BioMeridian, although such license agreement is subject to claims of breach and likely renegotiation. We have also entered into an agreement with a distributor in Europe to distribute the IONIQ ProLung Test. This distribution agreement is currently in the process of being renegotiated. We may be unable to enter into necessary distribution and licensing agreements to market the product. In addition, even if we enter into such relationships, we may have limited or no control over the sales, marketing and distribution activities of third parties. Failure to enter into or maintain these arrangements with third parties or failure to develop our own sales and marketing infrastructure could substantially impair or even eliminate our ability to market the IONIQ ProLung Test. Our reliance on collaboration with others may adversely affect our ability to continue to operate, pursue our technology development program, or to achieve profitability. Any clinical trials that we conduct may not be completed on schedule, or at all, or may be more expensive than we expect, which could prevent or delay regulatory authorization(s) of our products or impair our financial position.   The commencement or completion of any clinical trials that we conduct may be delayed or halted for numerous reasons, including, but not limited to, the following:     ● the FDA or other regulatory authorities suspend or place on hold a clinical trial, or do not give us the authorization required to start a clinical trial;   ● the data and safety monitoring committee or applicable hospital institutional ethics review board recommends that a trial be placed on hold or suspended;   ● fewer patients meet our clinical study criteria and our enrollment rate is lower than we expected;   ● patients do not return for follow-up as expected;   ● clinical trial sites decide not to participate or cease participation in a clinical trial;   ● patients experience adverse side effects or events related to our IONIQ ProLung Test or for unrelated reasons;   ● third-party clinical investigators do not perform our clinical trials on schedule or consistent with the clinical trial protocol and good clinical practices, or other third-party organizations do not perform data collection and analysis in a timely or accurate manner;   ● we fail regulatory inspections of our manufacturing facilities requiring us to undertake corrective action or suspend or terminate our clinical trials;   ● governmental regulations require additional testing not currently contemplated in our pivotal trial or implement administrative actions;   ● pre-clinical or clinical data are interpreted by third parties in unanticipated ways; or   ● our trial design is considered inadequate to demonstrate safety and/or efficacy of the product.   Patient enrollment in clinical trials and completion of patient follow-up in clinical trials depend on many factors, including the size of the target patient population, the nature of the trial protocol, the proximity of patients to clinical sites and patient compliance. Delays in patient enrollment or failure of patients to continue to participate in a study may cause an increase in costs and delays or result in the failure of the trial.   Our clinical trial costs will increase if we have material delays in those trials or if we need to perform more or larger trials than planned. Adverse events during a clinical trial could cause us to repeat a trial, terminate a trial or cancel an entire program. Should our clinical development plan be delayed, this could have a material adverse effect on our operations and financial condition.   We engage in related party transactions, which result in a conflict of interest involving our management.   We have engaged in the past, and may continue to engage, in related party transactions. Related party transactions present difficult conflicts of interest, could result in disadvantages to our company and may impair investor confidence, which could materially and adversely affect us. Related party transactions could also cause us to become materially dependent on related parties in the ongoing conduct of our business, and related parties may be motivated by personal interests to pursue courses of action that are not necessarily in the best interests of our company and our stockholders.   IONIQ ProLung testsTests may produce false positive and false negative results.   A patient may have a low composite risk score as measured by the IONIQ ProLung Test and still have lung cancer. A low composite risk score does not preclude risk for lung cancer. This patient, however, based upon a false negative IONIQ ProLung Test, may be subject to less stringent clinical vigilance. The IONIQ ProLung Test is to be used in conjunction with all available clinical risk factors and findings including physician/health practitioner judgment. Nonetheless, a false negative result generated from the IONIQ ProLung Test may contribute to a patient not receiving a timely diagnosis of or treatment for existing lung cancer.   By contrast, a patient may have a high composite risk score but not have lung cancer. Such a patient may be subject to greater clinical vigilance or unnecessary invasive procedures, such as biopsy, thus subjecting the patient to greater morbidity and potential mortality due to a falsely positive IONIQ ProLung Test. Again, since the IONIQ ProLung Test is to be used in conjunction with other clinical findings, and not as a stand-alone diagnostic test, such a case would be unlikely. Nonetheless, a false positive result generated from the IONIQ ProLung Test may contribute to a patient receiving unnecessary procedures such as CT Scans and lung biopsies. False positive and false negative results would likely erode market acceptance of the IONIQ ProLung Test and would thus harm our business, cash flows and operations.   25 Our clinical studies may produce unfavorable results.   Unfavorable results could prevent the IONIQ ProLung Test from obtaining FDA and other regulatory authorizations. Unfavorable clinical results may also prevent the Company from adequately commercializing the IONIQ ProLung Test in foreign markets such as the European Union which would harm our business, cash flows and operations. The Company may not have a cost-effective resolution to overcome either of these obstacles.   Our success depends upon our ability to effectively market our products.   If the IONIQ ProLung Test does not achieve market acceptance, we will be unable to generate significant revenues. The commercial success of the IONIQ ProLung Test will depend primarily on convincing healthcare providers to adopt and use the IONIQ ProLung Test. To accomplish this, we, together with any other marketing or distribution collaborators, will need to convince members of the medical community the benefits of the IONIQ ProLung Test through, for example, published papers, presentations at scientific conferences, and additional clinical data. Medical providers will not use our product unless we can demonstrate that our product consistently produces results comparable or superior to existing products and has acceptable safety profiles and costs. If we are not successful in these efforts, market acceptance of the IONIQ ProLung Test could be limited. Even if we demonstrate the effectiveness of the IONIQ ProLung Test, medical practitioners may still use other products. If the IONIQ ProLung Test does not achieve broad market acceptance, we will be unable to generate significant revenues, which would have a material adverse effect on its business, cash flows, and results of operations. We are dependent on key personnel, who may terminate their employment at any time.   Our success depends, in large part, upon the talents and skills of company management and other key personnel. During the past year, we have experience high turnover in our executive management team, including the positions of CFO and CEO, as well as a majority of the board of directors. The CEO was terminated for cause, and the other officers and directors resigned as part of the turmoil that followed. We have filled some, but not all vacated positions and are at risk of losing additional employees in the future. There can be no assurance that we would be able to find suitable replacements for all such personnel or that suitable personnel could be obtained for an amount that we could afford. In the future, a need for additional qualified personnel is expected in order to operate the business successfully. There can be no assurance that we will be able to attract employees of adequate qualification or that we would be able to afford such personnel.   Competition for skilled personnel in our market is intense and competition for experienced scientists may limit our ability to hire and retain highly qualified personnel on acceptable terms. Members of our management, scientific and medical teams may terminate their employment with us on short notice. The loss of the services of any of our executive officers or other key employees could potentially harm our business, operating results or financial condition.   Other medical companies with which we compete for qualified personnel have greater financial and other resources, different risk profiles and a longer history in the industry than we do. They also may provide more diverse opportunities and better chances for career advancement. Some of these characteristics may be more appealing to high-quality candidates than what we have to offer. If we are unable to continue to attract and retain high-quality personnel, the rate and success at which we can develop and commercialize our product would be limited.   A pandemic, epidemic or outbreak of an infectious disease in the markets in which we operate or that otherwise impacts our facilities or suppliers could adversely impact our business. If a pandemic, epidemic, or outbreak of an infectious disease including the recent outbreak of respiratory illness caused by a novel coronavirus (COVID-19) first identified in Wuhan, Hubei Province, China, or other public health crisis were to affect our markets or facilities. Consequences of the coronavirus outbreak are resulting in disruptions in or restrictions on our ability to travel. If such an infectious disease broke out at our office, facilities or work site, our operations may be affected significantly, our productivity may be affected, our ability to complete projects. In response to the COVID-19 situation, federal, state and local governments (or other governments or bodies) are considering placing, or have placed, restrictions on travel and conducting or operating business activities. At this time those restrictions are very fluid and evolving. We have been and will continue to be impacted by those restrictions. Given that the type, degree and length of such restrictions are not known at this time, we cannot predict the overall impact of such restrictions on us. As such, the impact these restrictions may have on our financial position, operating results and liquidity cannot be reasonably estimated at this time, but the impact may be material. In addition, due to the speed with which the COVID-19 situation is developing and evolving, there is uncertainty around its ultimate impact on public health, business operations and the overall economy; therefore, the negative impact on our financial position, operating results and liquidity cannot be reasonably estimated at this time, but the impact may be material. Risks Related to Our Regulatory and Legal Environment   We must obtain regulatory clearance or approval in the US and other non-European Union markets to be able to commence marketing and sales in those markets.   In many countries, we are required to obtain government clearance or approval before we can market and sell a medical device like the IONIQ ProLung Test. Obtaining the necessary clearance or approval is a complex, costly, and time-consuming process, which differs from country-to-country. Failure to comply with the premarket authorization requirements of a country can result in serious penalties, including fines, recalls, seizure of product, suspension of sales, refusal to grant other approvals or clearances, increased requirements for quality control or (in severe cases) criminal prosecution. The imposition of any of the afore-mentioned penalties would adversely affect our business. We have received a CE Mark for the marketing of the IONIQ ProLung Test in the European Union. We are seeking clearance to sell the IONIQ ProLung Test in the US and plan to seek clearance in other markets. Each market has unique regulatory requirements. In the US, FDA marketing clearance will be required before the IONIQ ProLung Test may be marketed in the US. We expect to be subject to the premarket notification orde novoclearance pathway, but may be subject to premarket approval, which would substantially lengthen (and substantially increase the costs associated with) the regulatory process beyond that which is currently anticipated. As with the FDA review process, there are numerous risks associated with the review of medical devices by foreign regulatory agencies. The foreign regulatory agencies may request additional data to demonstrate the clinical safety and efficacy of a product. It is possible that we may not obtain the clearance or approval required to market the IONIQ ProLung Test in the US or another significant potential market, which would harm our long-term revenue potential.   Even if marketing clearance (or approval) is granted, such clearance (or approval) may include significant limitations on the indicated use(s) for which the product may legally be marketed – i.e., the clearance may not allow us to make the type of claims that we believe we need to make for the IONIQ ProLung Test to be commercially viable. Delays in obtaining regulatory clearance(s) or approval(s) would also harm our financial condition. A failure to obtain required clearances for our desired indication(s) in a timely fashion, particularly in the US, would significantly harm our long-term ability to continue as a going concern.   Even if we receive regulatory clearance or approval for the IONIQ ProLung Test, we still may not be able to successfully commercialize it and the revenue that we generate from its sales, if any, may be limited.   The commercial success of the IONIQ ProLung Test will depend on its acceptance by the medical community, including physicians, patients and health care payors. The degree of market acceptance of the IONIQ ProLung Test will depend on a number of factors, including:     ● demonstration of clinical safety, efficacy, and utility;   ● relative convenience and ease of use;   ● the prevalence and severity of any adverse effects;   ● the willingness of physicians to order the IONIQ ProLung Test and of the target patient population to try new medical devices;   ● the introduction of any new products that in the future may become available to compete with the IONIQ ProLung Test;   ● pricing and cost-effectiveness;   ● the inclusion or omission of the IONIQ ProLung Test in applicable treatment guidelines;   ● the effectiveness of our or any future collaborators’ sales and marketing strategies;   ● limitations or warnings contained in FDA-cleared (or approved) labeling;   ● our ability to obtain and maintain sufficient third-party coverage and reimbursement from government health care programs, including Medicare and Medicaid, private health insurers and other third-party payors; and   ● the willingness of patients to pay out-of-pocket in the absence of third-party coverage or adequate reimbursement.   In addition, even if we obtain regulatory clearances or approvals, the timing or scope of any clearances or approvals may prohibit or reduce our ability to commercialize the IONIQ ProLung Test successfully. For example, if the approval process takes too long, we may miss market opportunities and give other companies the ability to develop competing products or establish market dominance. Any regulatory clearance (or approval) we ultimately obtain may be limited or subject to restrictions or post-market commitments that render the IONIQ ProLung Test not commercially viable. For example, third-party payers may deny coverage for the test or set reimbursement for the IONIQ ProLung Test procedure at a rate that is insufficient to cover provider costs, or regulatory authorities may grant clearance or approval contingent on ProLung’s performance of costly post-marketing clinical trials. Moreover, product clearances and approvals may be withdrawn for non-compliance with regulatory standards or if problems occur following the initial marketing of the product. Any of the foregoing scenarios could materially harm the commercial success of the IONIQ ProLung Test. 27 If we obtain FDA clearance, we will be subject to Medical Device Reporting (“MDR”) requirements, which may lead to inquiries, injunctions, or liabilities.   Under the FDA MDR regulations, medical device manufacturers are required to submit information to the FDA when they receive a report or become aware that a device has caused or may have caused or contributed to a death or serious injury or has or may have a malfunction that would likely cause or contribute to death or serious injury if the malfunction were to recur. All manufacturers placing medical devices on the market in the European Economic Area are legally bound to report any serious or potentially serious incidents involving devices they produce or sell to the regulatory agency, or other Competent Authority, in whose jurisdiction the incident occurred. Were we to learn of a reportable adverse event, we would submit the required information to the relevant regulatory agency, to which the agency may respond with additional request(s) for information if the agency has any questions.   Malfunction of our products could result in future voluntary corrective actions, such as recalls, including corrections, or customer notifications, or agency action, such as inspection or enforcement actions. If malfunctions do occur, we may be unable to correct the malfunctions adequately or prevent further malfunctions, in which case we may need to cease distribution of the affected products, initiate voluntary recalls, and redesign the products. Regulatory authorities may also take actions against us, such as ordering recalls, imposing fines, or seizing the affected products. Any corrective action, whether voluntary or involuntary, will require the dedication of our time and capital, distract management from operating our business, and may harm our reputation and financial results.   Existing US regulatory laws and cost-saving initiatives may harm our revenues and create additional expenses.   To the extent that we market the IONIQ ProLung Test in the US, federal healthcare reform may adversely affect the results of our domestic operations. The Patient Protection and Affordable Care Act, or the Affordable Care Act, was enacted in March 2010. The Affordable Care Act included several provisions intended to reduce the volume of medical procedures, which, in turn, could result in reduced demand for our products and increased downward pricing pressure. While the Affordable Care Act is intended to expand health insurance coverage to uninsured persons in the US, the impact of any overall increase in access to healthcare on potential sales of the IONIQ ProLung Test is uncertain at this time. Further, we cannot predict with any certainty what other impact the Affordable Care Act may have on our business.   Recently proposed healthcare reform measures could hinder or prevent the commercial success of our products.   The pricing and reimbursement environment may change in the future and become more challenging as a result of any of one several possible regulatory developments, including policies advanced by the United States government, new healthcare legislation, repeal or reform of the Affordable Care Act, or fiscal challenges faced by government health administration authorities. The US government has shown significant interest in pursuing healthcare “reform” and reducing healthcare costs. For example, aggregate reductions to Medicare payments to providers of up to 2% per fiscal year were implemented starting in 2013. Any government-adopted reform measures that further decrease the amount of reimbursement our customers receive from governmental and other third-party payers could potentially adversely affect our business.   We will be subject to healthcare fraud and abuse law regulations.   Our operations may be directly or indirectly affected by various broad federal, state or foreign healthcare fraud and abuse laws. In particular, the US federal Anti-Kickback Statute prohibits any person from knowingly and willfully soliciting, receiving or providing any remuneration (including any kickback, bribe or rebate), directly or indirectly, overtly or covertly, in cash or in kind, in return for referring an individual for the furnishing or arranging for the furnishing of any item or service for which payment may be made in whole or in part under a Federal health care program, or in return for the ordering, leasing, purchasing, or arranging for or recommending the ordering, purchasing or leasing of any good, facility, item or service, for which payment may be made in whole or in part under federal healthcare programs, such as the Medicare and Medicaid programs. We are also subject to the fraud and abuse provisions of the US federal HIPAA statute, which created federal criminal laws that prohibit executing a scheme to defraud any healthcare benefit program, willfully obstructing a criminal investigation of a health care offense, or making false statements or concealing a material fact relating to payment for health-care benefits, items or services, and federal “sunshine” laws that require transparency regarding financial arrangements with healthcare providers, such as the reporting and disclosure requirements imposed by the Affordable Care Act on certain medical device manufacturers regarding any “transfer of value” made or distributed to prescribers and other healthcare providers. In addition, the US federal False Claims Act prohibits persons from knowingly filing, or causing to be filed, a false claim to, or the knowing use of false statements to obtain payment from the federal government. Suits filed under the False Claims Act, known as “qui tam” actions, can be brought by any individual on behalf of the government and such individuals, commonly known as “whistleblowers,” may share in any amounts paid by the entity to the government in fines or settlement. When an entity is determined to have violated the False Claims Act, it may be required to pay up to three times the actual damages sustained by the government, plus civil penalties for each separate false claim. Various states have also enacted laws modeled after the federal False Claims Act.   Many states and other countries have also adopted laws similar to each of the above federal laws, such as anti-kickback and false claims laws which may apply to items or services reimbursed by any third-party payor, including commercial insurers, as well as laws that restrict our marketing activities with physicians, and require us to report consulting and other payments to physicians. Some states and other countries mandate implementation of commercial compliance programs to ensure compliance with these laws. We also are subject to foreign fraud and abuse laws, which vary by country.   If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us now or in the future, we may be subject to penalties, including civil and criminal penalties, damages, fines, exclusion from governmental healthcare programs, and the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our financial results.   ProLungOur clinical study designs have not been reviewed by the FDA.   Our PL-208 and PLW-216 clinical study wasstudies were designed without input from the FDA. In 2018, before breaking the study data blind and analyzing the amassed clinical data for our PL-208 study, we collaborated with the FDA through two formal Pre-Submission Meetings regarding our PL-208 Study Statistical Analysis Plan, Study design, device output and statistical approaches. We have received significant comments from the FDA, some but not all of which have been resolved. There can be no assurance that the FDA will approve the design of PL-208 and PLW-216 or any future study, or agree that the results generated in our PL-208 and PLW-216 trial is sufficient for FDA to approve or clear the IONIQ ProLung Test for our desired indication for use. Even if our clinical studies produce favorable results, the FDA may refuse regulatory clearance and or require additional research causing delays in the launch and commercialization of the IONIQ ProLung Test in the US.theUS.   ProlungOur clinical studies have resulted in statistically significant variability and the results may be insufficient to gain marketing clearance from the FDA.   Our clinical studies may produce unfavorable results which could prevent or delay ProLung from obtaining FDA and other regulatory clearances. In November 2018, we reported our PL-209 study results indicating day-to-day variability is repeatable; however, same-day variability is statistically significant with a 2% difference in scores though the clinical impact is unclear. In January 2019, we announced preliminary results for our PL-208 study. In the Validation Set (n=174 subjects), the IONIQ ProLung Test demonstrated a sensitivity of 68%, specificity of 49%, Positive Predictive Value (PPV) of 70%, Negative Predictive Value (NPV) of 47% and an Accuracy of 61%. In, the fall of 2019 we announced the results of PLW-216. In the study of 486 subjects with 418 effective, the IONIQ ProLung Test returned results of 84% sensitivity, 73% specificity, 78% Positive Predictive Value (PPV) and 80% Negative Predictive Value (NPV). The performance from PL-208, PL-209 and PL-209PLW-216 are unlikely to be sufficient to gain marketing clearance from the FDA.   Risks Related to Our Intellectual Property   We may be unable to protect our intellectual property rights, which are important to the potential value of our products and company.   We have obtained patent protection, through ownership and licensing, for aspects of the IONIQ ProLung Test in a limited number of jurisdictions, and there is no guarantee that such protection will be available for the IONIQ ProLung Test in all jurisdictions, or, that once obtained, we would be able to enforce such rights. Disputes may arise between us and others as to the scope, validity and ownership rights of patents. Any defense of patents could prove to be costly and time consuming and we may not be in a position, or may deem it unadvisable, to carry on such a defense. In addition, the owner of patented technology that we license may fail to maintain underlying patents or may breach its obligations to us.   There can be no assurance that any patent applications that we or our licensors file will result in patents being issued or that, if issued, the patents will afford protection against competitors with similar technology. There can also be no assurance that any patents issued to us or that we license will not be infringed on or circumvented by others, or that others will not obtain patents that we would need to license or circumvent. Our patents may not contain claims that are sufficiently broad to prevent others from using our technologies or developing competing products. Competitors may be able to use technologies in competing products that perform substantially the same as our technologies but avoid infringing on our patent claims. Under these circumstances, our patents would be of little commercial value. Additionally, there can be no assurance that patents, even after issuance, will be upheld by applicable courts. There can be no assurance that licenses, which might be required for our processes or products, would be available on reasonable terms, or that patents issued to others would not prevent us from developing and marketing its products. To the extent that we also rely on un-patented trade secrets, there can be no assurance that others will not independently develop substantially equivalent proprietary information and techniques or otherwise gain access to our trade secrets or disclose such technology. Disclosure of our trade secrets would impair our competitive position and adequate remedies may not exist in the event of unauthorized use or disclosure of our confidential information. Further, to the extent that our employees, consultants or contractors use trade secret technology or know-how owned by others in their work for us, disputes may arise as to the ownership of related inventions.   We rely on an exclusive license maintained by the licensor, and if the licensor does not adequately defend the license our business may be harmed.   We currently have one exclusive license to US patents. We rely on the licensor to maintain these patents and otherwise protect the intellectual property covered by this license. We have limited control over these activities or over any other intellectual property that may be related to our in-licensed intellectual property. For example, we cannot be certain that activities by the licensor have been or will be conducted in compliance with applicable laws and regulations. We may have no control or input over whether, and in what manner, our licensor may enforce or defend the patents against a third-party. The licensor may enforce or defend the patent less vigorously than if we had enforced or defended the patents ourselves. Further, the licensor may not necessarily seek enforcement in scenarios in which we would feel that enforcement was in our best interests. For example, the licensor may not enforce the patents against a competitor of ours who is not a direct competitor of the licensor. If our in-licensed intellectual property is found to be invalid or unenforceable, then the licensor may not be able to enforce the patents against a competitor of ours. If we fail to meet our obligations under the license agreement, then the licensor may terminate the license agreement. If the license agreement is terminated, the former licensor may seek to enforce the intellectual property against us. We may choose to terminate the license agreement, and doing so would allow a third party to seek and obtain an exclusive license to the patents. If a third party obtains an exclusive license to intellectual property formerly licensed to us, then the third party may seek to enforce the intellectual property against us.   We may incur significant costs and liability if we infringe, or are accused of infringing on, the intellectual property rights of others.   We may incur significant liability if we infringe the patents and other proprietary rights of third parties, including damages, inability to sell or license the IONIQ ProLung Test without obtaining a license from the patent holder, which may not be available at commercially reasonable terms or at all, and we may have to redesign the IONIQ ProLung Test so that it does not infringe on the third-party patent, which redesign may not be possible or could require substantial funds or time. Although no third party has asserted a claim of infringement against us, in the event that our technologies infringe or violate the patent or other proprietary rights of third parties, we may be prevented from pursuing product development, manufacturing or commercialization of any product that uses these technologies. There may be patents held by others of which we are unaware that contain claims that our product or operations infringe. In addition, given the complexities and uncertainties of patent laws, there may be patents of which we may ultimately be held to infringe, particularly if the claims of the patent are determined to be broader than we believe them to be. Even if we are ultimately successful in our defense of an infringement case, the costs of litigation would significantly harm our business.   We may need to market the IONIQ ProLung Test under a different name in the EU to avoid the risk of infringement.   We are aware of a company that markets an assay to be used as a liquid biopsy test for lung cancer detection under the name Epi proLung, which is trademarked in the EU. If we market the IONIQ ProLung Test in the EU, we may be subject to the risk of infringement. If we determine, at the time we choose to market the IONIQ ProLung Test in the EU, that we may infringe on this trademark, we might need to change the name under which we market the IONIQ ProLung Test in the EU. Parts, components, and software incorporated in the ProLungIONIQ System may become obsolete.   The ProLungIONIQ System consists of both custom and off the shelf parts and software. As off the shelf components age they may become obsolete requiring ProLung to procure, test and validate replacement components, parts and software for the ProLungIONIQ System.   Risks Related to Capital Stock   Our SEC Reports contain projections and forward-looking statements that may not prove to be accurate.   Our SEC Reports, including those delivered herewith, contain projections that are based on our assumptions and judgments as of the date of such reports concerning future events and are subject to significant uncertainties and contingencies, many of which are beyond our control. Our actual results may materially differ from the results we have projected. In addition, our SEC Reports contain forward-looking statements that involve known and unknown risks and uncertainties. All statements other than those of historical facts, including those regarding business strategy, plans and objectives of management, projected costs, and expected benefits are forward-looking statements. These forward-looking statements are based on information and expectations as of the date of the respective SEC Report. Important factors that could cause our results to differ materially from expectations include those set forth in this “Risk Factors” section and elsewhere in our SEC Reports. We disclaim any obligation or intent to update these forward- looking statements.   Many of our directors have failed to timely file required reports with the SEC.   Section 16(a) of the Securities Exchange Act requires our officers, directors and persons who own more than 10% of our common stock to file reports concerning their ownership of common stock with the SEC and to furnish us copies of such reports. We believe that several of our directors have not timely filed all stock ownership and trading reports required by SEC rules. However, we believe that all of our officers and directors have currently filed all such required reports. The failure of the officers and directors to file such reports could lead to legal action by the SEC or third parties against the directors and potentially against the Company. Any such legal actions would be disruptive, consume financial and personnel resources, and harm the reputation of the Company including its ability to continue to raise capital. This may inhibit the ability of the Company to execute its business plan and continue as a going concern.   There is no trading market for our common stock, and it is possible that no trading market will develop.   There is currently no public trading market for the Company’s common stock, and there is no assurance that a public market for the Company’s common stock will exist in the future. We do not currently meet the listing requirements of the Nasdaq Stock Market or any other exchange. We do meet the requirements for listing on an over- the-counter market; however, an application for quotation in the over-the-counter market must be submitted by one or more market makers who: 1) are approved by the Financial Industry Regulatory Authority, 2) who agree to sponsor the security, and 3) who demonstrate compliance with SEC Rule 15(c)2-11 before initiating a quote in a security on the over-the-counter market.   If our common stock commences trading in the over-the-counter market, it will likely be subject to penny stock rules, which may restrict liquidity. If our common stock becomes tradable in the secondary market, it may be subject to the penny stock rules adopted by the SEC that require brokers to provide extensive disclosure to their customers prior to executing trades in penny stocks. These disclosure requirements may cause a reduction in the trading activity of the Company’s common stock, which in all likelihood would make it difficult for our shareholders to sell their securities. Penny stocks generally are equity securities with a price of less than $5.00 (other than securities registered on certain national securities exchanges or quoted on the Nasdaq Stock Market). Penny stock rules require a broker-dealer, prior to a transaction in a penny stock not otherwise exempt from the rules, to deliver a standardized risk disclosure document that provides information about penny stocks and the risks in the penny stock market. The broker-dealer also must provide the customer with current bid and offer quotations for the penny stock, the compensation of the broker-dealer and its salesperson in the transaction, and monthly account statements showing the market value of each penny stock held in the customer’s account. The broker-dealer must also make a special written determination that the penny stock is a suitable investment for the purchaser and receive the purchaser’s written agreement to the transaction. These requirements may have the effect of reducing the level of trading activity, if any, in the secondary market for a security that becomes subject to the penny stock rules. The additional burdens imposed upon broker-dealers by such requirements may discourage broker-dealers from effecting transactions in our securities, which could severely limit their market price and liquidity of our securities. These requirements may restrict the ability of broker-dealers to sell the Company’s common stock and may affect the Purchaser’s ability to resell the common stock. Provisions in our charter documents and under Delaware law could discourage a takeover that stockholders may consider favorable and may lead to entrenchment of management.   Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that could significantly reduce the value of our shares to a potential acquirer or delay or prevent changes in control or changes in our management without the consent of our Board of Directors. The provisions in our charter documents include the following:     ● a classified Board of Directors with three-year staggered terms, which may delay the ability of stockholders to change the membership of a majority of our Board of Directors;         ● no cumulative voting in the election of directors, which limits the ability of minority stockholders to elect director candidates;         ● the exclusive right of our Board of Directors to elect a director to fill a vacancy created by the expansion of the Board of Directors or the resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on our Board of Directors;         ● the prohibition on removal of directors without cause;         ● the ability of our Board of Directors to authorize the issuance of shares of preferred stock and to determine the price and other terms of those shares, including preferences and voting rights, without stockholder approval, which could be used to significantly dilute the ownership of a hostile acquirer;         ● the ability of our Board of Directors to alter our bylaws without obtaining stockholder approval;         ● the requirement that a special meeting of stockholders may be called only by the President of the Company or by the Board of Directors, which may delay the ability of our stockholders to force consideration of a proposal or to take action, including the removal of directors.   In addition, these provisions would apply even if we were to receive an offer that some stockholders may consider beneficial.   We are also subject to the anti-takeover provisions contained in Section 203 of the Delaware General Corporation Law. Under Section 203, a corporation may not, in general, engage in a business combination with any holder of 15% or more of its capital stock unless the holder has held the stock for three years or, among other exceptions, the Board of Directors has approved the transaction.   We are subject to various regulatory regimes, and may be adversely affected by inquiries, investigations and allegations that we have not complied with governing rules and laws.   In light of our status as a reporting company and the early stage of our business, we are subject to a variety of laws and regulatory regimes in addition to those applicable to all businesses generally. For example, we are subject to the reporting requirements applicable to U.S. reporting issuers, such as the Sarbanes-Oxley Act of 2002, and certain state and provincial securities laws. In addition, because we are in an early stage of development and intend on issuing securities to raise capital and use acquisitions for growth, our actions will be governed by state and federal securities laws and laws governing the issuance of securities, which are complex. In connection with such laws, we may be subject to periodic audits, inquiries, and investigations. Any such audits, inquiries, and investigations may divert considerable financial and human resources and adversely affect the execution of our business plan.   Through such audits, inquiries, and investigations, we, or a regulator, may determine that we are out of compliance with one or more governing rules or laws. Remedying such non-compliance diverts additional financial and human resources. In addition, in the future, we may be subject to a formal charge or determination that we have materially violated a governing law, rule, or regulation. We may also be subject to lawsuits as a result of alleged violation of the securities laws or governing corporate laws. Any charge or allegation, and particularly any determination, that we had materially violated a governing law would harm our ability to enter into business relationships, recruit qualified officers and employees, and raise capital. If a market develops for our common stock, we expect the market price to be volatile.   The market prices of securities of smaller companies tend to be highly volatile. If a market develops for our common stock, of which there can be no assurance, our stock price may change dramatically as the result of announcements of our quarterly results, slow revenue growth, absence of profits, the rate of our expansion, significant litigation or other factors or events that would be expected to affect our business or financial condition, results of operations, and other factors specific to our business and future prospects. In addition, the market price for our common stock may be affected by various factors not directly related to our business, including the following:     ● intentional manipulation of our stock price by existing or future stockholders;         ● short selling of our common stock or related derivative securities;         ● a single acquisition or disposition, or several related acquisitions or dispositions, of a large number of our shares of common stock;         ● the interest, or lack of interest, of the market in our business sector;         ● the adoption of governmental regulations and similar developments in the U.S. or abroad that may affect our ability to offer our products and services or affect our cost structure; and         ● economic and other external market factors, such as a general decline in market prices due to poor economic indicators or investor distrust.   We have never paid, and do not intend to pay in the future, dividends on our common stock. We have never declared nor paid any cash dividends on our capital stock. We currently intend to retain any future earnings and do not expect to pay any dividends in the foreseeable future. It is unlikely that investors will derive any current income from ownership of our stock. This means that the potential for economic gain from ownership of our stock depends on appreciation of our stock price and will only be realized by a sale of the stock at a price higher than the purchase price.   Item 1B. Unresolved Staff Comments   None.   Item 2. Properties   We currently maintain a corporate office at 757 East South Temple,350 W. 800 N., Suite 150,214, Salt Lake City, Utah 84102.84103. We currently lease this property for $4,140$3,600 a month. This location is approximately 4,6573,635 square feet of office space.   Item 3. Legal Proceedings   We know of no existing or pending legal proceedings against us, nor are we involved as a plaintiff in any proceeding or pending litigation. There are no proceedings in which any of our directors, officers or any of their respective affiliates, or any beneficial stockholder is an adverse party or has a material interest adverse to our interest.   Item 4. Mine Safety Disclosures.   Not applicable. PART II   Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters, and Issuer Purchasers of Equity Securities Market Price of and Dividends on the Registrant’s Common Equity and Related Stockholder Matters.   (a) Market Information   Our common stock is not listed or traded on any exchange or other market.   (b) Holders   As of December 31, 2018,April 30, 2021, there are 3,861,8494,094,916 shares outstanding held by approximately 800 stockholders of record.   (c) Dividends   We have not declared or paid dividends on our common stock since our formation, and we do not anticipate paying dividends in the foreseeable future. Declaration or payment of dividends, if any, in the future, will be at the discretion of our Board of Directors and will depend on our then current financial condition, results of operations, capital requirements and other factors deemed relevant by the Board of Directors. There are no contractual restrictions on our ability to declare or pay dividends.   (d) Securities Authorized for Issuance under Equity Compensation Plans   In April 2017 the Board of Directors approved the ProLung Inc. Stock Incentive Plan (the “Plan”). The shareholders approved the Plan in July 2017. The Plan authorizes the Board Compensation Committee to grant incentive stock options, non-incentive stock options, stock bonuses, restricted stock, and performance-based awards to directors, officers, employees and non-employee agents, consultants, advisers, and independent contractors of the Company or any parent or subsidiary of the Company. The following table sets forth certain information with respect to the Plan and any other plans plan as of December 31, 2018:2020:   Plan Category   Number of securities to be issued upon exercise of outstanding options, warrants and rights (a)   Weighted-average exercise price of outstanding options, warrants and rights   Number of securities remaining available for future issuance under equity compensation plans (excluding securities reflected in column (a))     Number of securities to be issued upon exercise of outstanding options, warrants and rights (a)   Weighted-average exercise price of outstanding options, warrants and rights   Number of securities remaining available for future issuance under equity compensation plans (excluding securities reflected in column (a))   Equity compensation plans approved by security holders     310,635   $ 7.41   231,865       663,016     $ 5.19       0   Equity compensation plans not approved by security holders   1,227,809   $ 5.21   N/A     1,305,595   $ 5.09   N/A   Total   1,538,444   $ 5.65   231,865     1,968,611   $ 5.07   0     The total number of initial shares of Common Stock authorized for issuance under the Plan was 500,000 shares; the authorized shares will automatically increase on January 1st of each year, for ten consecutive years, commencing on January 1, 2018, by the lesser of (i) 40,000 shares of Common Stock (i.e., 8% of the shares of the shares originally authorized to be issued), or (ii) such number of shares of common stock (if any) the Board may earlier designate in writing.

Asmultiple cancers thereby expanding the therapeutic window, significantly improving survivability, and reducing the cost of healthcare. One in two Americans will be diagnosed with cancer during their lifetime an done in five will die. Clinical literature shows that early detection can save lives and money. We operate at the confluence of our Electrical Impedance Analytics (EIA) technology and artificial intelligence (AI). We are developing an advanced multi-cancer screening technology for early detection that will expand the therapeutic window, dramatically improve survivability and reduce the cost of healthcare. The first planned product utilizing our proprietary analytic platform, the IONIQ ProLung Test™ for lung cancer, ishas been designated a Breakthrough Device by the leading cause of cancer death, early detection makes a substantial improvement in survival in a large population group. Timely identification of malignancy is essentialU.S. FDA. We remain fully committed to gaining U.S. FDA regulatory de novo clearance and subsequently commercializing the IONIQ ProLung Test™ for patients and their families. Currently, patients often wait from three months to three and one-half years to have the risk of malignancy assessed through periodic CT scan surveillance. Until malignancy is determined to be likely, invasive biopsy and treatment are significantly delayed. Current statistics reflect a 17% survival rate at five years for those diagnosed with lung cancer.   We believe the IONIQ ProLung Test for lung cancer, in conjunction with the discovery of a nodule by CT scan, provides a more rapid assessment of the risk of malignancy, which must be determined prior to biopsy. Since a lung biopsy is invasive and may require life threatening thoracic surgery, physicians, patients, and insurance companies typically delay biopsy and therapy until the risk of malignancy outweighs the risk of further diagnostic procedures. For these patients, the delay reduces the treatment opportunity window and may cause sustained emotional trauma.   Results of Operations   The following discussion is included to describe our consolidated financial position and results of operations. The consolidated financial statements and notes thereto contain detailed information that should be referred to in conjunction with this discussion.   Fiscal Year Ended December 31, 2018,2020, compared to Fiscal Year Ended December 31, 20172019   Revenue and Cost of Revenue. During the year ended December 31, 20182020 or 2017,2019, we had no revenue. Operating Expenses.Expenses   Research and Development Expense. Research and development expense for the year ended December 31, 20182020 was $2,036,792738,734 compared to research and development expense of $1,630,837$2,099,463 for the year ended December 31, 2017;2019; representing an increasea decrease of $405,955.$1,360,729. The net increasedecrease was due to the following events: During 2018,2019, we entered into anamended a license agreement with our Chief Medical Officer resulting in a total additionalProLung China. The license agreement was amended whereby ProLung China will provide us its clinical trial data, know-how and improvements which we will use outside the greater China area. As part of this agreement we committed to pay ProLung China $560,000 and issue shares based on the completion of certain milestones. During 2019 we recorded apporoximately $1,450,000 of expense of approximately $300,000. We also recorded approximately $450,000 of stock-based compensationunder this agreement. Also during 2018 related to our 2017 stock option grant to our employees classified as research and development employees in full or in part. Due to the options being granted during the last quarter of 2017,2020, we only recorded approximately $200,000 ofhad lower stock based compensation during 2017.2020 due to our 2020 employee option issuances having a four-year vesting period compared to the 2019 employee issuances having a one-year vesting period.   DueThe decrease during 2020 was was slightly offset by us having sufficient funds in 2020 to the uncertainty of when the Companyhire a new employee to research additional uses for our test. We would receive revenue and in anticipation of future research projects, on December 31, 2018 the Company reassigned all of inventory toexpect our research and development supplies.This resulted in approximately ancosts to remain relatively constant during 2021 unless we do not receive additional $264,000of research and development expense. The above increase was offset by a decrease in research and development salary expense. In an effort to best utilize our resources we scaled back our employees to only essential personal with a major reduction in force at the end of the third quarter. We also had decreased consulting and clinical costs during 2018. Our on-site clinical trials began winding down at the end of 2017 and early part of 2018. Our focus during 2018 was to obtain FDA clearance, which was done mostly with our in-house personnel.funding.   Selling, General and Administrative Expense.Selling, general and administrative expense for the year ended December 31, 2018,2020 was $2,494,455,$1,330,926 compared to selling, general, and administrative expense of $3,615,495$1,464,515 for the year ended December 31, 2017,2019, representing a decrease of $1,121,040.$133,589. This decrease was due to the following events:decrease in amortization of stock based compensation as discussed above. Also, we have implemented various cost controls and a shift of our funds being utilized for developing our IONIQ ProLung Test rather than unneeded administrative costs.   During 2017, we commenced an offering of our common stock whereby we incurred significant up-front travel, legal, professional and consulting expense during 2017. These costs primarily related to advisory fees, investor relations and brand awareness as we commenced the offering process and were not included as part of deferred offering costs. In February 2018, we elected to terminate our relationship with our underwriter and postponed and, ultimately cancelled, the offering. We did not incur these costs during the majority of the year ended December 31, 2018. We also had decreased salary expense during 2018. In June 2018, our CEOThis decrease was terminated for cause, which was followedoffset slightly by other administrative personnel either resigning or were asked to leave to minimize personnel cost. During 2018, we updated our estimate on when our former CEO would vest in his performance based stock options. It was decided these options would not vest and resulted in us reversing all expense recognized in 2017. Offsetting these decreases was an increase in stock based compensation related to our 2017Board members and consultants to the Board. We increased the size of our Board during the end 2019 and compensate them with stock option grantoptions. As a result, there were more options issued to our employees classified as administrative employees. During 2018, we had a full year of vesting expense compared to a partial yearthe Board during 2017.2020   Other Expense. Other expense for the year ended December 31, 20182020 was $3,178,035 as$657,956 compared to $122,980 for$1,055,909 the year ended December 31, 2017.2019. The increasedecrease costs consist of the following:   ● Interest Expense – From March through May 2018, we issued approximately $3 million in 8% convertible promissory notes. The convertible notes were issued with a beneficial conversion feature and cash and equity Interest Expense – Interest increased in 2020 to ($783,965) from ($407,358) in 2019 due to increased debt levels and the associated amortization of additional loan costs. Under these new notes, we incurred both interest and the amortization of discount which we did not have during the year ended December 31, 2017. We anticipate our interest expense during 2019 will be consistent with 2018. However, if the convertible notes are converted, any unamortized discount will be immediately charged against interest. ● Write-Off of Deferred Offering Costs – During 2017 and 2018, the Company filed a Registration Statement and numerous amendments related to a potential public offering of the Company’s common stock. There was no assurance that any shares would be offered and sold pursuant to such Registration Statement. Through February 2018, the Company incurred cash offering costs totaling $303,401 which were to be offset against the proceeds received if such offering was completed. In February 2018, the Board suspended the offering, and in June 2018, the Board decided not to pursue the public offering in the near future and the Company wrote-off the deferred offering costs to expense. ● Impact of Warrant Restructure– In December 2018, the Board decided to lower the exercise price of certain warrants issued in 2016 and 2017 with an original exercise price of $12 to $5.20 per share. The Company recorded the $2,179,612 difference in fair value of the warrants before and after the change as an impact of warrant restructure.   36 Gain/ Loss on Debt Extuingsuishment – During the year ended December 31, 2019, the holders of certain convertible debt were given the opportunity to extend the maturity date of their notes and receive a lower conversion rate. Since the adjustment was so significant we considered the notes extinguished and subsequently reissued. As a result, we recognized a $648,551 loss on the extinguishment. In April 2020, the Company entered into an SBA Loan Paycheck Protection Program (the “PPP”) under the recently enacted Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) administered by the U.S. Small Business Administration (the “SBA”). The Company received total proceeds of $126,000 from the SBA Loan. Subject to certain conditions, the SBA Loan may be forgiven in whole or in part by applying for forgiveness pursuant to the CARES Act and the PPP. The Company received notice in November 2020 the loan had been forgiven and recorded the forgiveness as gain from debt extinguishment.   Liquidity and Capital Resources   The following is a summary of our key liquidity measures at December 31, 2018,2020 and 2017:2019:       December 31,2018     December 31, 2017   Cash   $ 249,286   $ 636,639                     Current assets     273,539       971,884   Current liabilities     (507,353 )     (321,320 )                   Working (deficit) capital   $ (233,814 )   $ 650,564       December 31,       2020     2019                 Cash   $ 185,126     $ 207,421                     Current assets     190,553       212,848   Current liabilities     (1,730,413 )     (2,535,877 )                   Working capital deficit   $ (1,539,860 )   $ (2,323,029 ) We need additional capital to continue our operations. DuringWe issued $2,369,500 in convertible notes during the year ended December 31, 2018,2020. Also, we completed a financingreceived $126,000 in whichPPP loans. In order for us to continue operations we were able to satisfy our capital requirements. We continue towill need additional fundscapital which will require us to fund operationsissue equity securities, debt securities and obtain FDA clearancerights to market the ProLung Test. If we receive FDA clearance, of which there can beacquire equity securities. We have no assurance, we expect that our need forexisting commitment to provide capital, will expand. Givenand given our early stage of development, we may be unable to raise sufficient capital when needed and, in any case, will likely be required to pay a high price for capital.   Our future capital requirements and adequacy of available funds and ability to raise necessary capital will depend on many factors including:     ● Our ability to find a commercial market for our completion of our current clinical studyIONIQ ProLung Test and the extent to which the results are positive; obtain needed regulatory clearance   ● our ability to obtain regulatory clearance in markets outside of Europe, including in the US; ● our ability to successfully commercialize our ProLung Test, ProLung System, and related products and the market acceptance of these products; ● the timing of our orders, if any, and the pricing and payment terms of those orders; ● reimbursement for our ProLung Test by Medicaid, Medicare and private third-party payors; ● our ability to establish and maintain collaborative arrangements with distributors for the development and commercialization of certain product opportunities; ● the cost of manufacturing and production scale-up; ● ourOur financial results;   ● the cost and availability of capital generally; and   ● the occurrence of unexpected adverse expenses or events. Notes Payable Since our inception, the principal source of our financing has come from the issuance of equity securities and from debt financing. As of December 31, 2018, our outstanding debt financing includes the following notes payable. Convertible Notes Payable   In March 2018, we began issuing 8% convertible promissory notes (“convertible notes”). The convertible notes are unsecured. Principal and accrued interest are due two years from the date of issuance.March 31, 2022.

Interest accruing from the date of issuance to the conversion date shall be paid on the maturity date. If the Company completes a public offering of its common stock, the convertible promissory notes and accrued interest automatically convert into common stock at the lower of i) 90% of the public offering price or ii) $6.30 per share.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and contingencies as of the date of the financial statements and reported amounts of revenues and expenses during the reporting periods. We evaluate our estimates on an on-going basis. We base our estimates on historical experience and on other assumptions that are believed to be reasonable under the circumstances. However, future events may cause us to change our assumptions and estimates, which may require adjustment. Actual results could differ from these estimates. We have determined that for the periods reported in this Annual Report on Form 10-K the following accounting policies and estimates are critical in understanding our financial condition and results of operations. 38 Revenue Recognition – Revenue is recognized by the Company when a binding sales or service agreement exists between the parties, services have been rendered, the price for the services is fixed or determinable, collection is reasonably assured, and the Company has no significant obligations remaining with respect to the arrangement. Inventory– Inventory is valued at the lower of cost or market value, with cost determined based on the first-in-first-out method. Management evaluates inventory for obsolescence based on expectations about future demand and marketability of products, and if necessary, reduces inventory to the lower of cost or market through the use of an inventory valuation account for obsolescence. The estimated cost of inventory not expected to be converted to cash within one year is reflected as “Inventory, noncurrent” in the consolidated balance sheet.Due to the uncertainty of when the Company would receive revenue and in anticipation of future research projects, on December 31, 2018 the Company reassigned all inventory to research and development.   Long-lived Assets– Long-lived assets, including property and equipment, and intangible assets are tested for recoverability whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. When such events occur, we compare the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset or asset group to the carrying amount of the long-lived asset or asset group. If this comparison indicates that there is an impairment, the amount of the impairment is calculated based on fair value.   Stock-based Compensation – The Company measures the cost of employee and consulting services received in exchange for an award of equity instruments based on the grant-date fair value of the award. The awards issued are valued using a fair value-based measurement method. The resulting cost is recognized over the period during which an employee or consultant is required to provide services in exchange for the award, usually the vesting period.   Emerging Growth Company– We are an “emerging growth company” under the federal securities laws and will be subject to reduced public company reporting requirements. In addition, Section 107 of the JOBS Act also provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. In other words, an “emerging growth company” can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. Although we have not delayed the adoption of any accounting standards, we may choose to take advantage of the extended transition period for complying with new or revised accounting standards in the future.   Off Balance Sheet Arrangements   The Company has not had any off-balance sheet arrangements.   Item 7A. Quantitative and Qualitative Disclosures About Market Risk   This item is not applicable to the Company because the Company is a smaller reporting company.   Item 8. Financial Statements and Supplementary Data   Financial Statements   Reference is made to the consolidated financial statements and accompanying notes included in this report, which begin on page F-1.   Supplemental Financial Data   This item is not applicable to the Company because the Company is a smaller reporting company.   Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.   Not applicable.   3941   Item 9A. Controls and Procedures   Disclosure Controls and Procedures   We maintain “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that are designed to ensure that information required to be disclosed by us in reports we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the Commission’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, management recognized that disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable assurance of achieving the desired control objectives, and we necessarily are required to apply our judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures.   Our management, including our principal executive officer and principal financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2018,2020, and concluded that the disclosure controls and procedures were not effective, because certain deficiencies involving internal controls constituted material weaknesses as discussed below. The material weaknesses identified did not result in the restatement of any previously reported financial statements or any other related financial disclosure, nor does management believe that it had any effect on the accuracy of our financial statements for the current reporting period.   Management’s Annual Report on Internal Control Over Financial Reporting   Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Our internal control system was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes, in accordance with GAAP. Because of inherent limitations, a system of internal control over financial reporting may not prevent or detect misstatements. Additionally, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate due to change in conditions, or that the degree of compliance with the policies or procedures may deteriorate.   Our management, including our principal executive officer and principal accounting officer, conducted an evaluation of the effectiveness of our internal control over financial reporting using the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control—Integrated Framework (2013). Based on its evaluation, our management concluded that there are material weaknesses in our internal control over financial reporting.reporting and therefore the internal controls are considered not effective. A material weakness is a deficiency, or a combination of control deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim financial statements will not be prevented or detected on a timely basis. As of December 31, 2018,2020, the following material weaknesses existed:   The Company did not maintain effective entity-level internal controls as defined by the framework issued by COSO. Specifically, the Company did not effectively segregate certain accounting duties due to the small size of the Company’s accounting staff. In addition, there were lapses in the Company’s expense documentation and related controls. Due to this material weaknesses,weakness, management has concluded that our internal controls over financial reporting were not effective as of December 31, 2018.2020.   In order to mitigate these material weaknesses to the fullest extent possible we engage a third-party accounting firm to provide additional expertise in accounting. Furthermore, regular meetings are held with the audit committee and the audit committee approves all audit functions. If at any time, we determine a new control can be implemented to mitigate these risks at a reasonable cost, it is implemented as soon as possible.   This annual report does not include an attestation report of the Company’s registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Company’s registered public accounting firm pursuant to Commission rules that permit the Company to provide only management’s report in this annual report. This report shall not be deemed to be filed for purposes of Section 18 of the Exchange Act, or otherwise subject to the liabilities of that section, and is not incorporated by reference into any filing of the Company, whether made before or after the date hereof, regardless of any general incorporation language in such filing.   Changes in Internal Control Over Financial Reporting   There was no change in our internal control over financial reporting that occurred in the year ended December 31, 20182020 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.   Item 9B.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 20182020 and 2017,2019, and the results of theirits operations and theirits cash flows for each of the years thenin the two-year period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America.   Explanatory Paragraph Regarding Going Concern Matter   The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the financial statements, the Company has sufferedincurred substantial and recurring losses to date from operations, continues to have a stockholders’ deficit and has a net capital deficiency that raisesis currently dependent on debt and equity financing, which creates substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.   Basis for Opinion These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.   We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the entity’sCompany’s internal control over financial reporting. Accordingly, we express no such opinion.   Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.   /s/ MaloneBailey, LLPSadler, Gibb & Associates, LLC www.malonebailey.com We have served as the Company’s auditor since 2015.2020.

The accompanying consolidated financial statements do not include any adjustments that might result relating to the recoverability and classification of the asset carrying amounts or the amount and classification of liabilities that might result from the outcome of this risk and uncertainty.   The ability of the Company to continue as a going concern is dependent on the Company successfully obtaining additional funding, developing products that can be sold profitably, and generating cash through operating activities. Management’s plans include issuing equity or debt securities to fund capital requirements and developing ongoing operations.   Use of Estimates – The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results could differ from those estimates.   Concentration of Credit Risk – Financial instruments that potentially subject the Company to a concentration of credit risk consists principally of cash. The Company has no cash balances during the years ended December 31, 20182020 and 20172019 in excess of federally insured limits. The Company places its cash with a high credit quality financial institution.   Fair Value of Financial Instruments – For the notes payable and convertible debentures classified as long-term liabilities, the estimated fair value is approximately equal to the carrying value based on the interest rates and other terms of debt.   Cash and Cash Equivalents – The Company considers all unrestricted highly liquid investments purchased with a maturity of three months or less to be cash equivalents. The Company had no cash equivalents as of December 31, 2018 or 2017.2020 and 2019.   Trade Receivables and Credit Policies – Accounts receivable are recorded at the invoiced amount, with foreign currencies reflected in U.S. dollars (based on the exchange rate on the date of sale and adjusted to current exchange rates at the end of each reporting period), and do not bear interest. The Company uses an allowance for doubtful accounts to reflect the Company’s best estimate of the amount of probable credit losses in accounts receivable. Account balances will be charged off against the allowance when the account receivable is considered uncollectible. Inventory– Inventory is valued at the lower of cost or market value, with cost determined based on the first-in-first-out method. The estimated cost of inventory not expected to be converted to cash within one year is reflected as “Inventory, noncurrent” in the consolidated balance sheets, although all inventory is ready and available for sale at any moment.Due to the uncertainty of when the Company would receive revenue and in anticipation research projects, the Company reassigned inventory to research and development. ProLung, Inc. and Subsidiary Notes to Consolidated Financial Statements Property and Equipment – Property and Equipment is stated at cost and depreciated using the straight-line method over useful lives of 3 to 5 years. Leasehold improvements are amortized over the shorter of the life of the lease or the service life of the improvements. Maintenance, repairs, and renewals that neither materially add to the value of the property nor appreciably prolong its life are charged to expense as incurred. Gains or losses on dispositions of property and equipment are included in the results of operations.   Intangible Assets – As further discussed in Note 4 to these consolidated financial statements, intangible assets consist of rights to certain patent applications acquired in December 2015 under a Patent Assignment Agreement. These intangible assets will beare being amortized over an estimated useful life of eighteen years, with periodic evaluation for impairment. Impairment or Disposal of Long-Lived Assets - Long-lived assets are reviewed for impairment when facts and circumstances indicate that the carrying value of the asset may not be recoverable. When necessary, impaired assets are written down to estimated fair value based on the best information available. Estimated fair value is generally based on either appraised value or measured by discounting estimated future cash flows. Considerable management judgment is necessary to estimate discounted future cash flows. Accordingly, actual results could vary significantly from such estimates. We did not record an asset impairment charge for either of the years ended December 31, 2020 and 2019. F-7 ProLung, Inc. Notes to Financial Statements   Research and Development – The Company expenses research and development costs as incurred. Research and development costs primarily consist of clinical study costs, consulting fees, compensation of employees related to activities to obtain regulatory approval for the Company’s devices, and materials and supplies.   Employee Stock-based Compensation – The Company measures the cost of employee and non-employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award and to recognize it as compensation expense over the period the employee and non-employee is required to provide service in exchange for the award, usually the vesting period.   Non-Employee Stock-based Compensation – The Company accounts for non-employee stock-based compensation at fair value on the measurement date. The measurement of stock-based compensation is subject to periodic adjustment as the underlying equity instruments vest. Income Taxes – The Company accounts for income taxes under the asset and liability method. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and for operating loss and tax credit carry-forwards. Deferred income tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred income tax assets and liabilities of a change in tax rates is recognized in operations in the period that includes the enactment date. The Company has established a valuation allowance to reduce deferred income tax assets to their realizable values based on whether it is more likely than not that such deferred income tax assets will be realized. At December 31, 20182020 and 2017,2019, the Company has recorded a full valuation allowance against the net deferred tax assets related to temporary differences and operating losses because there is significant uncertainty as to the realizability of the deferred tax assets.   The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement.The Company currently believes that all significant filing positions are above this threshold and therefore, the Company has no significant reserves for uncertain tax positions and no adjustments to such reserves are required by generally accepted accounting principles. No interest or penalties have been levied against the Company and none are anticipated; therefore, no interest or penalty has been included in our provision for income taxes in the statements of operations.   Basic and Diluted Loss Per Share – The Company computes basic loss per share by dividing net loss by the weighted-average number of common shares outstanding during the period. The Company computes diluted loss per share by dividing net loss by the sum of the weighted-average number of common shares outstanding and the weighted-average dilutive common share equivalents outstanding. The computation of diluted loss per share does not assume exercise or conversion of securities that would have an anti-dilutive effect. As ofDecember 31, 2018,2020 and 2017,2019, the following items were excluded from the computation of diluted net loss per common share as their effect is anti-dilutive:     For the Year Ended     December 31,     December 31,     2018   2017     2020   2019   Warrants to purchase shares     1,227,809       1,184,998       1,305,595       1,255,667   Stock options     310,635       331,000       663,016       526,135   Convertible notes     698,919       201,155       2,728,358       1,774,351   F-8 ProLung, Inc. and Subsidiary Notes to Consolidated Financial Statements Foreign Currency Policy –Transactions in foreign currencies are initially recorded at the rates of exchange prevailing on the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are retranslated into the Company’s functional currency at the rates prevailing on the balance sheet date. Exchange differences arising on the settlement of monetary items, and on the retranslation of monetary items, are reported as other income (expense) and included in net loss for the period. The Company had no foreign currency transactions during 2018 or 2017. Related Parties – The Company discloses related party transactions which are in the normal course of operations and are measured at the exchange amount.   Recent Accounting Pronouncements Emerging Growth Company – We are an “emerging growth company” under the federal securities laws and will be subject to reduced public company reporting requirements. In May 2014,addition, Section 107 of the JOBS Act also provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. In other words, an “emerging growth company” can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. F-8 ProLung, Inc. Notes to Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09,Revenue from Contracts with Customers (Topic 606), which was amended with ASU No. 2015-14, ASU No. 2016-08, ASU No. 2016-10, ASU No. 2016-11, ASU No. 2016-12 and ASU No. 2016-20. These new standards supersede all existing revenue recognition requirements, including most industry specific guidance. The new standard requires a company to recognize revenue when it transfers goods or services to customers in an amount that reflects the consideration that the company expects to receive for those goods or services. The Company currently has no revenue and the implementation of this standard has no current effect.Statements   Leases – In February 2016, the FASB issued ASU No. 2016-02:LeasesASU 2016-02 requires companies to generally recognize on the balance sheet operating and financing lease liabilities and corresponding right-of-use assets. ASU 2016-02 willwould be effective for the Company’s 2019 fiscal year; however, since the Company is an Emerging Growth Company and has made the election to adopt certain accounting standards when they would be applicable for private companies which is the fiscal year beginning January 1, 2020 on a2022. The Company will use the modified retrospective basisbasis. The Company entered into a three-year lease agreement in May 2019 and earliermanagement is evaluating how the implementation of this standard will affect its balance sheet and statement operations. Convertible Notes Payable – In August 2020, the FASB issued ASU 2020-06, “Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40),” which simplifies the accounting for convertible instruments, reduces complexity for preparers and practitioners and improves the decision usefulness and relevance of the information provided to financial statement users. ASU 2020-06 also amends the guidance for the derivatives scope exception for contracts in an entity’s own equity to reduce form-over-substance-based accounting conclusions. ASU 2020-06 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted. Management is currently evaluatingpermitted, but no earlier than fiscal years beginning after December 15, 2020. The Company has not yet determined the impact of the pending adoption this standard on our financial position, results of ASU 2016-02 on the Company’s consolidated financial statements and based on the Company’s one month-to-month lease agreement does not anticipate a material impact.operations or cash flows.   The Company has reviewed other recent accounting pronouncements and has determined that they will not significantly impact the Company’s results of operations or financial position.   Note 2 – InventoryResearch and Development Agreement   Inventory principally consistedOn July 29, 2019, the Company amended a license agreement dated April 10, 2013 between the Company and ProLung Biotech Wuxi / ProLung China (Wuxi).

Wuxi has yet to earn any revenue but has been conducting clinical trials. The license agreement was amended whereby Wuxi will provide the Company its clinical trial data, know-how and improvements which the Company will use outside the greater China area. This amendment further requires full collaboration (i.e., protocols and methodologies) between the two entities.

ProLung, Inc. and Subsidiary Notes to Consolidated Financial Statements The Company considers these options to be performance based. Solely for accounting purposes, the Company originally estimated FDA marketing authorization would be obtained by December 2018. Based on this estimate, the most probable number of options to be issued would have been 75,000. On the date of issuance the Company computed the value of these options using the Black-Scholes Pricing Model using the following assumptions:   Expected life     5.70 Years   Exercise price   $ 8.00   Expected volatility     116 % Expected dividends     None   Risk-free interest rate     1.84 % ProLung, Inc. The resulting value of $472,000 ($6.29 per option) would be amortized over the vesting period which was estimatedNotes to be through December 31, 2018. Through December 31, 2017, the Company recorded $134,196 of expense. During 2018, the Company concluded it was improbable that FDA marketing authorization would be obtained by December 31, 2019. The Company updated their estimate whereby the conditions for vesting will not be met by December 31, 2019. Based on the estimate, the number of options decreased from 75,000 to zero and the resulting value from $472,000 to zero. As a result, $134,196 of compensation expense recognized during the year ended December 31, 2017 was reversed during the year ended December 31, 2018. As of December 31, 2018, there are currently 231,865 options available for issuance under the Plan. As noted above, we have issued performance-based options to our CEO, whereby we could issue up to 37,500 options; which are included in the above options available for issuance under the Plan.Financial Statements   A summary of option activity for the yearsyear ended December 31, 2018 and 20172020 is presented below:             Weighted   Aggregate             Weighted   Aggregate         Weighted   Average   Intrinsic         Weighted   Average   Intrinsic     Shares   Average   Remaining   Value of     Shares   Average   Remaining   Value of     Under   Exercise   Contractual   Vested     Under   Exercise   Contractual   Vested     Options   Price   Life   Options     Options   Price   Life   Options   Outstanding at December 31, 2016     -                            Issued     331,000     $ 8.05               Forfeited/Expired     -                   Outstanding at December 31, 2017     331,000     $ 8.05     10.0 years         Outstanding at December 31, 2019     526,135     $ 5.85       8.7 years               Issued     145,954     $ 6.75               136,881     $ 2.57                   Adjustment     (75,000 )   $ 12.00               -     $ -                   Forfeited/Expired     (91,319 )   $ 8.19               -     $ -                          Outstanding at December 31, 2018     310,635     $ 7.41     9.16 years   $ -   Vested at December 31, 2018     276,823     $ 7.34     9.20 years   $ -   Outstanding at December 31, 2020     663,016     $ 5.16       8.1 years     $ -   Vested at December 31, 2020     599,905     $ 5.44       7.9 years     $ -   Total stock-based compensation expense from stock grants (Note 8) options and warrants (Note 10) and related amortization have been included in the statements of operations as follows:     For the Year Ending       December 31,       2020     2019                 Research and development expense   $ 44,091     $ 97,433   Selling, general and administrative expense     375,572       461,689                     Total share-based compensation   $ 419,663     $ 559,122     Note 10 – Common Stock Warrants   The Company has issued warrants to purchase its common stock for payment of consulting services, in connection with the extension of a note payable, as incentives to investors,equity, debt and compensation reasons.
