Gene Therapy Overview
Genes are composed of sequences of deoxyribonucleic acid (“DNA”), which code for proteins that perform a broad range of physiologic functions in all living organisms. Although genes are passed on from generation to generation, genetic changes, also known as mutations, can occur in this process. These changes can result in the lack of production of proteins or the production of altered proteins with reduced or abnormal function, which can in turn result in disease.
Gene therapy is a therapeutic approach in which an isolated gene sequence or segment of DNA is administered to a patient, most commonly for the purpose of treating a genetic disease that is caused by genetic mutations. Currently available therapies for many genetic diseases focus on administration of large proteins or enzymes and typically address only the symptoms of the disease. Gene therapy aims to address the disease-causing effects of absent or dysfunctional genes by delivering functional copies of the gene sequence directly into the patient’s cells, offering the potential for curing the genetic disease, rather than simply addressing symptoms.
We are using modified non-pathogenic viruses for the development of our gene therapy treatments. Viruses are particularly well suited as delivery vehicles because they are adept at penetrating cells and delivering genetic material inside a cell. In creating our viral delivery vehicles, the viral (pathogenic) genes are removed and are replaced with a functional form of the missing or mutant gene that is the cause of the patient’s genetic disease. The functional form of a missing or mutant gene is called a therapeutic gene, or the “transgene.” The process of inserting the transgene is called “transduction.” Once a virus is modified by replacement of the viral genes with a transgene, the modified virus is called a “viral vector.” The viral vector delivers the transgene into the targeted tissue or organ (such as the cells inside a patient’s bone marrow). We have two types of viral vectors in development, LVV and AAV. We believe that our LVV and AAV-based programs have the potential to offer a significant therapeutic benefit to patients that is durable (long-lasting).
The gene therapies can be delivered either (1) ex vivo (outside the body), in which case the patient’s cells are extracted and the vector is delivered to these cells in a controlled, safe laboratory setting, with the modified cells then being reinserted into the patient, or (2) in vivo (inside the body), in which case the vector is injected directly into the patient, either intravenously (“IV”) or directly into a specific tissue at a targeted site, with the aim of the vector delivering the transgene to the targeted cells.
We believe that scientific advances, clinical progress, and the greater regulatory acceptance of gene therapy have created a promising environment to advance gene therapy products as these products are being designed to restore cell function and improve clinical outcomes, which in many cases include prevention of death at an early age. The FDA approval of several gene therapies in recent years indicates that there is supportive of a regulatory pathway forward for gene therapy products.

Danon Disease:
Danon disease (“DD”) is a multi-organ lysosomal-associated disorder leading to early death due to heart failure. Danon diseaseDD is caused by mutations in the gene encoding lysosome-associated membrane protein 2 (“LAMP-2”), a mediator of autophagy. This mutation results in the accumulation of autophagic vacuoles, predominantly in cardiac and skeletal muscle. Male patients often require heart transplantation and typically die in their teens or twenties from progressive heart failure. Along with severe cardiomyopathy, other Danon disease symptomsDD-related manifestations can include skeletal muscle weakness, liver disease, and intellectual impairment. There are no specific therapies available for the treatment of Danon disease.DD and medications typically utilized for the treatment of congestive heart failure (CHF) are not believed to modify progression to end-stage CHF. Patients with end-stage CHF may undergo heart transplant, which currently is available to a minority of patients, is associated with short- and long-term complications and is not curative of the disorder in the long-term. RP-A501 is in clinical trials as an in vivo therapy for Danon disease, which is estimated to have a prevalence of 15,000 to 30,000 patients in the U.S. and the EU, however new market research is being performed and the prevalence of patients may be updated in the future.EU.
Danon disease is an autosomal dominant, rare inherited disorder characterized by progressive cardiomyopathy which is almost universally fatal in males even in settings where cardiac transplantation is available. Danon disease predominantly affects males early in life and is characterized by absence of LAMP2Bexpression in the heart and other tissues. Pre-clinical models of Danon disease have demonstrated that AAV-mediated transduction of the heart results in reconstitution of LAMP2Bexpression and improvement in cardiac function.
As of December 31, 2020, weWe currently have one adeno-associated viral vector program targeting DD, RP-A501. We have treated fivesix patients in the RP-A501 Phase 1 clinical trial, which enrolled for adult and completed thepediatric male DD patients. This includes a first cohort of the study evaluating an initiala low-dose (6.7e13 genome copies (vg)/kilogram (kg)) in maleadult/older adolescent patients ageaged 15 or greater. The preliminary data announcedgreater (n=3), a second cohort evaluating a higher dose (1.1e14 vg/kg) in December 2020 for theadult/older adolescent patients aged 15 or greater (n=2), and we have initiated treatment in a pediatric cohort at a low dose cohortlevel (6.7e13 vg/kg; n=1).
Data disclosed from our Phase 1 study of RP-A501 in November 2021 and January 2022 included safety and clinical activity results from the three patients treated with the low dose of 6.7×1013 genome copies (gc)/kilogram (kg)6.7e13 vg/kg and early safety information from the two patients treated with the higher dose of 1.1×1014 gc/1.1e14 vg/kg, asand early safety information from the initial pediatric patient (pediatric cohort is age 8-14 years) treated with the low dose of 6.7e13 vg/kg.
Efficacy assessments include evaluation of New York Heart Association (“NYHA”) Functional Classification, which is the most commonly used heart failure classification system. NYHA Class II is where a patient exhibits a slight limitation of physical activity, is comfortable at rest, and ordinary physical activity results in fatigue, palpitation and/or dyspnea. Class I is where a patient exhibits no limitation of physical activity and ordinary physical activity does not cause undue fatigue, palpitation and/or dyspnea. Brain natriuretic peptide (BNP) is a blood-based evaluation and a key marker of heart failure with prognostic significance in CHF and cardiomyopathies. Other efficacy parameters include echocardiographic measurements of heart thickness, most notably the thickness of the cutoff dateleft ventricular posterior wall (LVPW), and importantly, measurement of November 2020.LAMP2B gene expression both via immunohistochemistry and Western blot, as obtained via endomyocardial biopsy. Biopsied heart tissue is also evaluated on electron microscopy for evidence of DD-associated tissue derangements, including the presence of autophagic vacuoles and disruption of myofibrillar architecture, each of which are characteristic of DD-related myocardial damage.
In November 2021 and January 2022, data for the ongoing Phase 1 trial of RP-A501 was presented, including efficacy parameters for the low and high dose cohorts in patients aged 15 and older with at least 12 months follow-up (n=5). An improvement in NYHA Class (from II to I) was observed in three patients (two low-dose and one high-dose) who had closely monitored immunosuppression with follow-up greater than one year and stabilization was observed in one low-dose patient without a closely monitored immunosuppressive regimen. A substantial improvement in BNP, a key marker of heart failure, was observed in all three low-dose patients and one high-dose patient. Among the three low-dose patients, treatedBNP decreased from a pretreatment baseline by 57% at 24 months, 79% at 18 months, and 75% at 15 months, respectively. In one high-dose patient, BNP decreased from a pretreatment baseline by 67% at 12 months. In patients with closely monitored immunosuppression (two low-dose and one high-dose) left ventricular (LV) posterior wall thickness improved (average 23% decrease compared to pretreatment baseline) and ejection fraction improved or stabilized (average 20% increase compared to pretreatment baseline) at 12 to 18 months on echocardiography. Severe and progressive wall thickening is a hallmark of the hypertrophic cardiomyopathy of Danon Disease and is a major contributor to early mortality in male patients. Cardiac output remained normal for all patients with improved or stable left heart filling pressures as measured by cardiac catheterization. Three low-dose patients and one high-dose patient demonstrated improvements in the 6-minute walk test (6MWT). One low-dose patient improved from a pretreatment baseline of 443 meters (m) to 467 m at 24 months. The second low-dose patient improved from a pretreatment baseline of 405 m to 410 m at 18 months. The third low-dose patient improved from a pretreatment baseline of 427 m to 435 m at 15 months. One high-dose patient improved from a pretreatment baseline of 436 m to 492 m at 12 months. Evidence of sustained cardiac LAMP2B gene expression by immunohistochemistry and Western blot with qualitative improvement of vacuoles and cardiac tissue architecture on electron microscopy was observed at both dose levels. Sustained cardiac LAMP2B gene expression by immunohistochemistry was observed in all three patients with a closely monitored immunosuppressive regimen. Specifically, LAMP2B gene expression by immunohistochemistry in the low-dose (6.7e13 vg/kg) was 68% in one patient at Month 12 and 92% in another patient at Month 9. In one patient who received the high-dose (1.1e14 vg/kg), LAMP2B gene expression by immunohistochemistry was 100% at Month 12.
One of the patients receiving therapy on the high dose cohort had progressive heart failure and underwent a heart transplant at Month 5 following therapy. This patient had more advanced disease than the 4 other adult/older adolescent patients who received treatment in the low and high dose cohort, cohorts, as evidenced by diminished LV ejection fraction (35%) on echocardiogram and markedly elevated LV filling pressure prior to treatment. His clinical course was characteristic of DD progression. Assessments regarding gene transduction from the explanted heart are summarized below:
Explanted Heart
Analysis of the explanted heart revealed significant fibrosis consistent with advanced DD.
Myocardial tissue from the explanted heart at 5 months post-treatment displayed 100% LAMP2B protein expression by immunohistochemistry throughout non-fibrotic cardiac regions including the ventricles and other essential targeted areas
RP-A501 showed manageable safety results.was generally well tolerated at the 6.7e13 vg/kg dose level, or lower dose. All observed adverse effects were reversible with no lasting sequelae. Early transaminase and creatinine kinase elevations returned to baseline or decreased. No unexpected and serious drug product-related adverse events or severe adverse events were observed.observed in this low dose cohort. The most common adverse events were predominantly mild, not associated with clinical symptoms and were related to elevated transaminases post treatment.post-treatment. Elevation in transaminases and creatinine kinases was observed in all three low-dose patients and returned to baseline levels within the first one to two months post-treatment. There was also a transient and reversible decline in platelets observed in these three patients. These changes were largely responsive to corticosteroids and other immunosuppressive therapies. All patients were given oral steroids to prevent or minimize potential immune-related events.
Corticosteroids were associated with transient exacerbation of DD-associated skeletal myopathy, which resolved upon discontinuation of steroid therapy. At the higher dose administered (1.1×1014 gc/(1.1e14 vg/kg), additional immunosuppressive therapies were stipulated and administered to mitigate the immune response associated with RP-A501. OneAs disclosed in December 2020, one of the two patients receiving the 1.1e14 vg/kg dose had more advanced heart failure than the others, and was the heaviest patient treated patients, who receivedto-date (receiving the higherhighest absolute AAV9 dose and had some degree of pre-existing anti-AAV9 immunity,dose). This patient experienced a non-persistent, immune-related event that was classified as a drug product-related serious adverse event. This thrombotic microangiopathy (“TMA”) event (which was later reclassified as a Sudden Unexpected Serious Adverse Reaction (“SUSAR”) was believed to be likely due to immune-mediated complement activation, resulting in reversible thrombocytopenia and acute kidney injury requiring eculizumab and transient hemodialysis. This patient returned to baseline within three weeks and regained normal kidney function.function within three weeks. (This event occurred in the same patient in whom RP-A501 was not associated with clinical stabilization or improvement, and who required a heart transplant 5 months post-therapy).
From the perspectiveFollowing transplant, this patient has been clinically stable and reports resolution of gene expression results, all three low dose patients demonstrated evidence of cardiac LAMP2B expression by Western blot and/or immunohistochemistry. In twoa baseline skeletal myopathy that was present prior to treatment. Analysis of the three patientsexplanted heart is described above. Of note, this patient had more advanced heart failure at time of treatment; the clinical protocol has been modified to exclude enrollment of DD with end-stage CHF/cardiomyopathy. In May 2021, 5 months after details of this event were disclosed and after recognition of complement-mediated TMA in other systemic AAV programs, the FDA placed the study on clinical hold. In response to the FDA’s clinical hold, we amended the trial protocol in order to enable more defined mechanisms for prevention, early recognition and management of complement-mediated adverse events. The FDA lifted the clinical hold on August 16, 2021 and dosing of the pediatric cohort was initiated in the fourth quarter of 2021.
Based on the activity observed in the low dose cohort who had closely monitored complianceand to mitigate complement-mediated TMA (safety concerns observed in the high dose cohort) and in agreement with the immunosuppressive regimen, high levels of cardiac LAMP2B expression were observed along with clinical biomarker improvements. In cardiac biopsies ofFDA, we are focusing on the low dose patients, LAMP2B gene expression was observed(6.7e13 vg/kg) and we will no longer administer doses of 1.1e14 vg/kg or higher in 67.8% of cells compared to normal as determined by immunohistochemistry at 9 months in one patient,this trial. Additional safety measures have been implemented and at 92.4% of cells compared to normal at month 12are reflected in the other patient. In this latterupdated trial protocol. These measures include exclusion of patients with end-stage heart failure, and a refined immunosuppressive regimen involving transient B- and T-cell mediated inhibition, with emphasis on preventing complement activation, while also enabling lower steroid doses and earlier steroid taper, with all immunosuppressive therapy discontinued 2-3 months following therapy. As announced in January 2022, the initial pediatric patient Western blot assessment showed 61%received RP-A501 therapy (6.7e13 vg/kg dose level) without evidence of normal LAMP2B protein expression at month 9. The 12-month Western blot datasignificant complement activation and with stable platelet levels; there was still pending for all three patients asno worsening of the data cutoff.
The first patient inpatient’s baseline DD-related skeletal myopathy during the low dose cohort was not as closely monitored for compliance with the immunosuppressive regimen as the other two patients. Although we did observe evidence of cardiac LAMP2B expression of approximately 15% of cells compared to normal as determined by immunohistochemistry at 12 months in this patient, we believe that such expression was likely limited by inconsistent compliance with the immunosuppressive regimen, as evidenced by transient increases in transaminase levels approximately one month after treatment and a lack of adverse events frequently associated with the immunosuppressive regimen. Additionally, in this patient, Western blot assessment showed 17.9% of normal LAMP2B protein expression at month 6.
At least two of the three low dose patients demonstrated key clinical biomarker improvements consistent with improved cardiac function. Brain natriuretic peptide, a key marker of heart failure, improved in all three patients, including by greater than 50% in the two patients with closely monitored immunosuppressive regimen compliance. Additionally, creatine kinase myocardial band either improved or stabilized in these two patients. For the patient with the potential inconsistent immunosuppressive regimen compliance, the creatine kinase myocardial band was higher than at baseline at month 12. Notably, all three patients showed visible improvements in autophagic vacuoles, a hallmark of Danon disease pathology, as assessed by electron microscopy of cardiac tissue via endomyocardial biopsy. Additionally, two of the three low dose patients with closely monitored immunosuppressive regimen compliance demonstrated improvement in cardiac output as measured by invasive hemodynamics, including one patient who showed a 1.62-fold improvement in cardiac output at month 12, and one patient who showed a 1.35-fold improvement at month 9. For the patient with the apparent inconsistent immunosuppressive regimen compliance, the cardiac output was lower at month 12 than at baseline.
We expect to announce updated data from our open-label Phase 1 trial of RP-A501 in the fourth quarter of 2021.weeks following RP-A501.
Fanconi Anemia Complementation Group A (FANCA):
FA, a rare and life-threatening DNA-repair disorder, generally arises from a mutation in a single FA gene. An estimated 60 to 70% of cases arise from mutations in the Fanconi-A (“FANCA”) gene, which is the focus of our program. FA results in bone marrow failure, developmental abnormalities, myeloid leukemia, and other malignancies, often during the early years and decades of life. Bone marrow aplasia, which is bone marrow that no longer produces any or very few red and white blood cells and platelets leading to infections and bleeding, is the most frequent cause of early morbidity and mortality in FA, with a median onset before 10 years of age. Leukemia is the next most common cause of mortality, ultimately occurring in about 20% of patients later in life. Solid organ malignancies, such as head and neck cancers, can also occur, although at lower rates during the first two to three decades of life.
Although improvements in allogeneic (donor-mediated) hematopoietic stem cell transplant (“HSCT”), currently the most frequently utilized therapy for FA, have resulted in more frequent hematologic correction of the disorder, HSCT is associated with both acute and long-term risks, including transplant-related mortality, graft versus host disease (“GVHD”), a sometimes fatal side effect of allogeneic transplant characterized by painful ulcers in the GI tract, liver toxicity and skin rashes, as well as increased risk of subsequent cancers. Our gene therapy program in FA is designed to enable a minimally toxic hematologic correction using a patient’s own stem cells during the early years of life. We believe that the development of a broadly applicable autologous gene therapy can be transformative for these patients.
Each of our LVV-based programs utilize third-generation, self-inactivating lentiviral vectors to correct defects in patients’ HSCs, which are the cells found in bone marrow that are capable of generating blood cells over a patient’s lifetime. Defects in the genetic coding of HSCs can result in severe, and potentially life-threatening anemia, which is when a patient’s blood lacks enough properly functioning red blood cells to carry oxygen throughout the body. Stem cell defects can also result in severe and potentially life-threatening decreases in white blood cells resulting in susceptibility to infections, and in platelets responsible for blood clotting, which may result in severe and potentially life-threatening bleeding episodes. Patients with FA have a genetic defect that prevents the normal repair of genes and chromosomes within blood cells in the bone marrow, which frequently results in the development of acute myeloid leukemia (“AML”), a type of blood cancer, as well as bone marrow failure and congenital defects. The average lifespan of an FA patient is estimated to be 30 to 40 years. The prevalence of FA in the U.S. and EU is estimated to be approximately 4,000 patients in total. In light of the efficacy seen in non-conditioned patients, the addressable annual market opportunity is now believed to be 400 to 500 patients collectively in the U.S. and EU.
We currently have one ex-vivo LVV-based program targeting FA, RP-L102. RP-L102 is our lead lentiviral vector-based program that we in-licensed from Centro de Investigaciones Energéticas, Medioambientales y Tecnológicas (“CIEMAT”), which is a leading research institute in Madrid, Spain. RP-L102 is currently being studied in our Phase 2 registrational enabling clinical trials treating FA patients at the Center for Definitive and Curative Medicine at Stanford University School of Medicine (“Stanford”), the University of Minnesota, Great Ormond Street Hospital (“GOSH”) in London and Hospital Infantil de Nino Jesus (“HNJ”) in Spain. The trial is expected to enroll a total of ten patients from the U.S. and EU with the first patient in this Phase 2 trial treated in December 2019. Patients will receive a single intravenous infusion of RP-L102 that utilizes fresh cells and “Process B” which incorporates a modified stem cell enrichment process, transduction enhancers, as well as commercial-grade vector and final drug product.
Resistance to mitomycin-C, a DNA damaging agent, in bone marrow stem cells at a minimum time point of one year post treatment is the primary endpoint for our ongoing Phase 2 study. Per agreement with the FDA and EMA, engraftment leading to bone marrow restoration exceeding a 10% mitomycin-C resistance threshold could support a marketing application for approval.
In December 2020, we presented updated interim data from our FA at the 62nd62nd American Society of Hematology (“ASH”) Annual Meeting. The FA data presented at the ASH Annual Meeting were from seven of the nine patients treated (out of twelve patients enrolled) as of October 2020 in both the U.S. Phase 1 and global Phase 2 studies of RP-L102 for FA. Patients in these studies received a single intravenous infusion of “Process B” RP-L102 which incorporates a modified stem cell enrichment process, transduction enhancers, as well as commercial-grade vector. Preliminary data from these studies support “Process B” as a consistent and reproducible improvement over “Process A” which was used in earlier academic FA studies.
Seven patients had follow-up data of at least two-months and three of the seven patients had been followed for twelve-months or longer. As patients are treated with gene therapy product without the use of a conditioning regimen, the data indicated that RP-L102 was generally well-tolerated with no significant safety issues reported with infusion or post-treatment. One drug related serious adverse event of Grade 2 transient infusion-related reaction was observed. In five out of the seven patients for whom there was follow-up data, evidence of preliminary engraftment was observed, with bone marrow (“BM”) vector copy numbers (“VCNs”) from 0.16 to 0.22 (long-term follow-up only) and peripheral VCNs ranging from 0.01 (2-month follow-up) to 0.11 (long-term follow-up). Further, two of the three patients with greater than 12-months follow-up showed evidence of increasing engraftment, mitomycin-C (“MMC”) resistance and stable blood counts, which suggests a halt in the progression of bone marrow failure. The third patient with greater than 12-month follow-up contracted Influenza B nine months post-treatment resulting in progressive BM failure, for which, such patient received a successful bone marrow transplant at 18months post-treatment.
In May 2021, we presented positive clinical data at the 24th Annual Meeting of the American Society of Gene and Cell Therapy (“ASGCT”). The preliminary data from the Phase 1/2 trials presented in a poster at ASGCT were from nine pediatric patients and showed increasing evidence of engraftment in at least six of the nine patients, including two patients with at least 15-months of follow-up and four patients with at least 6-months of follow-up. RP-L102 demonstrated a highly favorable tolerability profile with all subjects being treated without conditioning and with no sign of dysplasia. One patient experienced a Grade 2 transient infusion-related reaction.
In December 2021, we presented encouraging clinical data at the 63rd Annual Meeting of the American Society of Hematology (ASH). The preliminary results from the Phase 1/2 trials were presented in a poster at ASH were from eleven pediatric patients and showed increasing evidence of engraftment in at least six of eight patients for whom there are at least 12 months of follow-up, including bone marrow progenitor cell resistance to report longer-term follow up on thesemitomycin-C (MMC) ranging from 16-63% in six patients (bone marrow cells in FA patients are highly sensitive to DNA-damaging agents including MMC; this susceptibility to DNA damage is believed to mediate the second quarterFA-associated bone marrow failure and predisposition to malignancy. In addition to the development of 2021.MMC-resistance in BM hematopoietic cells, sustained peripheral VCN levels were seen in six of seven patients with at least 12-months of follow-up. One patient experienced an Influenza B infection approximately 9 months following treatment with concomitant progressive hematologic failure requiring allogeneic hematopoietic stem cell transplant, which was administered successfully; the remaining patients have not required transfusions. RP-L102 demonstrated a highly favorable tolerability profile with all subjects being treated without cytotoxic conditioning and no signs of dysplasia. The only RP-L102 related serious adverse event to-date has been a Grade 2 transient infusion-related reaction in one patient.
Leukocyte Adhesion Deficiency-I (LAD-I):
LAD-I is a rare autosomal recessive disorder of white blood cell adhesion and migration, resulting from mutations in the ITGB2 gene encoding for the Beta-2 Integrin component, CD18. Deficiencies in CD18 result in an impaired ability for neutrophils (a subset of infection-fighting white blood cells) to leave blood vessels and enter tissues where these cells are needed to combat infections. As is the case with many rare diseases, accurate estimates of incidence are difficult to confirm; however, several hundred cases have been reported to date.
Most LAD-I patients are believed to have the severe form of the disease. Severe LAD-I is notable for recurrent, life-threatening infections and substantial infant mortality in patients who do not receive an allogeneic HSCT. Mortality for severe LAD-I has been reported as 60 to 75% by age two in the absence of allogeneic HCST.
We currently have one ex-vivoex-vivo program targeting LAD-I, RP-L201. RP-L201 is a clinical program that we in-licensed from CIEMAT. We have partnered with UCLA to lead U.S. clinical development efforts for the LAD-I program. UCLA and its Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research is serving as the lead U.S. clinical research center for the registrational clinical trial for LAD-I, and HNJ isand GOSH serving as the lead clinical sitesites in Spain. GOSH inSpain and London, is also a site for the LAD-I trial.respectively. This study has received a $6.5 million CLIN2 grant award from the California Institute for Regenerative Medicine (“CIRM”) to support the clinical development of gene therapy for LAD-I.
The ongoing open-label, single-arm, Phase 1/2 registration enablingregistration-enabling clinical trial of RP-L201 has treated four severe LAD-I patients to assess the safety and tolerability of RP-L201 to date. The first patient was treated at UCLA with RP-L201 in the third quarter of 2019. Enrollment is now complete in this study.both the Phase 1 and 2 portions of the study; 9 patients have received RP-L102 at 3 investigative centers in the U.S. and Europe.
In AprilDecember 2021, Rocketwe presented positive clinical updates from RP-L201data at the Clinical Immunology Society (CIS)63rd Annual Meeting.Meeting of ASH. The Phase 1/2ASH oral presentation included preliminary data presented in a posterfrom eight of nine severe LAD-I patients, as defined by CD18 expression of less than 2%, who received RP-L201 treatment as of the November 8, 2021, data cut-off date. Eight patients had follow-up data of at CIS 2021 are fromleast three months, and four pediatricof the eight patients with severe LAD-I.had been followed for 12 months or longer. All infusions of RP-L201 waswere well tolerated withand no safety issues reported with treatment or post-treatment.drug product-related serious adverse events were reported. Evidence of preliminary efficacy was observed in all eight evaluable patients.

The firstadulthood and consistent with reversal of the severe LAD-I phenotype including six patients with at least 6 months of follow-up. Peripheral blood VCN levels have been stable and in the 0.54 – 2.94 copies per genome range. No patients had LAD-I related infections requiring hospitalization after hematopoietic reconstitution post-RP-L201. Additional updates presented in January 2022 included a ninth patient with 18-months follow up demonstrated durableachieving CD18 expression of ~40%, peripheral blood vector copy number (VCN) levels61% at 3 months, with the preliminary observation that all nine of 1.2 at 12-months post-treatment and resolution of skin lesions with no new lesions.

The third and fourth patients demonstrated highstable CD18 expression of ~70% and ~51%, respectively at 3-months post treatment, and peripheral blood VCN kinetics consistent with those of the first two patients.levels for each patient subsequent to month 3.
The LAD-I program received Regenerative Medicine Advanced Therapy (RMAT) designation from the FDA and Priority Medicines (PRIME) designation from the European Medicines Agency (“EMA”), completing the full complement of all U.S. and EU accelerated regulatory designations for the program.
We expect to announce initial Phase 2 data for our LAD-I program in the third quarter of 2021.
Pyruvate Kinase Deficiency (PKD):
Red blood cell PKD is a rare autosomal recessive disorder resulting from mutations in the pyruvate kinase L/R (“PKLR”) gene encoding for a component of the red blood cell (“RBC”) glycolytic pathway. PKD is characterized by chronic non-spherocytic hemolytic anemia, a disorder in which RBCs do not assume a normal spherical shape and are broken down, leading to decreased ability to carry oxygen to cells, with anemia severity that can range from mild (asymptomatic) to severe forms that may result in childhood mortality or a requirement for frequent, lifelong RBC transfusions. The pediatric population is the most commonly and severely affected subgroup of patients with PKD, and PKD often results in splenomegaly (abnormal enlargement of the spleen), jaundice and chronic iron overload which is likely the result of both chronic hemolysis and the RBC transfusions used to treat the disease. The variability in anemia severity is believed to arise in part from the large number of diverse mutations that may affect the PKLR gene. Estimates of disease incidence have ranged between 3.2 and 51 cases per million in the white U.S. and EU population. Industry estimates suggest at least 2,500 cases in the U.S. and EU have already been diagnosed despite the lack of FDA-approved molecularly targeted therapies. Market research indicates the application of gene therapy to broader populations could increase the market opportunity from approximately 250 to 500 patients per year.
We currently have one ex-vivoex-vivo LVV-based program targeting PKD, RP-L301. RP-L301 is a clinical stage program that we in-licensed from CIEMAT. The IND for RP-L301 to initiate the global Phase 1 study cleared in October 2019. This program has been granted US and EMA orphan drug disease designation.
This global Phase 1 open-label, single-arm, clinical trial is expected to enroll six adult and pediatric transfusion-dependent PKD patients in the U.S. and Europe. The trial will be comprised of three cohorts to assess RP-L301 in young pediatric (age 8-11), older pediatric (age 12-17) and adult populations. The trial is designed to assess the safety, tolerability, and preliminary activity of RP-L301, and initial safety evaluation will occur in the adult cohort before evaluation in pediatric patients. Stanford will serve as the lead site in the U.S. for adult and pediatric patients, HNJ will serve as the lead site in Europe for pediatrics, and Hospital Universitario Fundación Jiménez Díaz will serve as the lead site in Europe for adult patients. In July 2020, we treated the first patient in our clinical trial of RP-L301.
TheIn December 2021, we presented positive clinical data presented at the 2020 ASH63rd Annual Meeting wereof ASH. The ASH poster presentation included preliminary data from two adult PKD patients with significantsevere anemia and substantial transfusion requirements. Patient L301-006-1001 wasrequirements who were treated with RP-L301. Preliminary data from this first patient supported initial tolerability of RP-L301, hemoglobin improvement to a normal range at 3-months post treatment and additional normalization of hemolysis markers. The patient was 31-years of age at the time of enrollment and had been followed for 3-months post treatment as of the data cutoff dateNovember 3, 2021 cut-off date. Each of October 2020.
Patient L301-006-1001 received a cell dosethese patients had experience extensive PKD-related disease complications including hepatic iron overload. Both patients have had marked improvement in hemoglobin levels, from baselines of 3.9x106 cells/kilogram (“kg”)7.4 and 7.0 g/dL to 12-month values of 13.3 and 14.8 g/dL respectively; this represents an improvement from severe (Hb <8g/dL) to normal levels. Both patients have been transfusion independent subsequent to post-treatment hematopoietic reconstitution. Anemia resolution has been accompanied by marked improvement in additional markers of hemolysis, including bilirubin, erythropoietin, and reticulocyte counts. RP-L301 has been well tolerated in these adult patients, with ano drug product mean VCN of 2.73. For this patient, hematopoietic reconstitution was observed in less than two weeks. Furthermore, the patient attained peripheral blood VCN of 2.21 at 1-month and 1.55 at 3-months and normalized hemoglobin (“Hgb”) and hemolysis markers at 3-months post-treatment. In particular, at baseline, the patient had Hb of approximately 7.4 grams (“g”)/deciliter (“dL”) to Hb of 14.3 g/dL at 3-months post treatment with RP-L301. In the two years prior to enrollment, the patient underwent approximately 14 transfusion episodes; subsequent to engraftment from RP-L301 treatment, the patient to date has not required any red blood cell transfusions. The patient also exhibited normalization of bilirubin, lactate dehydrogenase and erythropoietin levels at 3-months post treatment, each of which had been substantially elevated prior to study enrollment. The patient also had an increase in hepcidin and a decrease in reticulocytes at 3-months post treatment.
The data from Patient L301-006-1001 indicated that RP-L301 was generally well-tolerated and there were norelated serious safety issuesadverse events or infusion-related complications observed 3-months post treatment. The patient experienced Grade 3 treatment-emergent adverse eventsthrough 12-months post-treatment. Both patients have reported improved quality of neutropenia, stomatitis, increased liver transaminase levels (ASTlife (QOL) following treatment with increases on FACT-An and ALT) and a Grade 4 treatment-emergent adverse event of hypertriglyceridemia; the investigator did not consider these adverse events related to RP-L301.
Patient L301-006-1001 also experienced Grade 2 serious adverse events of chest pain, dyspnea, and nausea during the apheresis collection. The investigator considered these events related to apheresis, hyperleukocytosis and the mobilizing agents. They resolved with supportive care and without sequelae. Other events included Grade 2 bone pain and Grade 3 leukocytosis. The second cohort of this study will enroll older pediatric patients and is expected to be initiated in the first half of 2021.
A second patient L301-006-1002, was 47 years old at the time of enrollment and had been recently treated with RP-L301, receiving a cell dose of 2.4x106 cells/kg with a mean drug product VCN of 2.08.
In March 2021, we announced updated positive preliminary clinical data from Phase 1 trial of RP-L301 for the treatment of PKD. The updated preliminary Phase 1 RP-L301 data are from two patients that showedadditional designated QOL evaluations sustained safety and tolerability 6- and 3-months after treatment, respectively. The two patients demonstrated durable normalization of hemoglobin levels from an average baseline of ~7.4 to 13.9 g/dL at 6-months post treatment in the first patient and from a baseline of ~7.0 g/dL to 13.8 g/dL at 3-months post treatment in the second patient. Respectively, the two patients demonstrated significant improvements in bilirubin 6- and 3-months after treatment, which had been substantially elevated prior to study enrollment.
The Phase 1 trial continues to enroll patients and we expect to report longer-term data in the fourth quarter of 2021, with a near-term update at the American Society for Cell and Gene Therapy Meeting in May 2021.through 12 months following therapy.
Infantile Malignant Osteopetrosis (IMO):
IMO is a genetic disorder characterized by increased bone density and bone mass secondary to impaired bone resorption. During normal growth and development small areas of bone are constantly being broken down by special cells called osteoclasts, then made again by cells called osteoblasts. In IMO, the cells that break down bone (osteoclasts) do not work properly, which leads to the bones becoming thicker and not as healthy. Untreated IMO patients may suffer from a compression of the bone-marrow space, which results in bone marrow failure, anemia, and increased infection risk due to the lack of production of white blood cells. Untreated IMO patients may also suffer from a compression of cranial nerves, which transmit signals between vital organs and the brain, resulting in blindness, hearing loss and other neurologic deficits.
IMO represents the autosomal recessive, severe variants of a group of disorders characterized by increased bone density and bone mass secondary to impaired bone resorption. IMO typically presents in the first year of life and is associated with severe manifestations leading to death within the first decade of life in the absence of allogeneic HSCT, although HSCT results have been limited to-date and notable for frequent graft failure, GVHD and other severe complications.
Approximately 50% of IMO results from mutations in the TCIRG1 gene, resulting in cellular defects that prevent osteoclast bone resorption. As a result of this defect, bone growth is markedly abnormal. It is estimated that IMO occurs in 1 out of 250,000-300,000 within the general global population, although incidence is higher in specific geographic regions including Costa Rica, parts of the Middle East, the Chuvash Republic of Russia, and the Vasterbotten Province of Northern Sweden.
We currently have one LVV-basedEffective December 2021, the Company made a decision to no longer pursue Rocket-sponsored clinical evaluation of RP-L401; this program targeting IMO, RP-L401. RP-L401 is a preclinical program that we in-licensed from Lund University, Sweden. This programwas returned to academic innovators. The Company has been granted ODDopted to focus available resources towards advancement of RP-A501, RP-L102, RP-L201 and Rare Pediatric Disease designation fromRP-L301, based on the FDA. We have partnered with UCLAcompelling clinical data to lead U.S. clinical development effortsdate and potential for the IMO programtherapeutic advancement in these severe disorders of childhood and UCLA will serve as the lead U.S. clinical site for IMO. The IND for RP-L401 to initiate a global Phase 1 study was cleared by the FDA in June 2020. The non-randomized, open-label Phase 1 clinical trial will enroll two pediatric patients, one month of age or older. The trial is designed to assess safety and tolerability of RP-L401, as well as preliminary efficacy, including potential improvements in bone abnormalities/density, hematologic status, and endocrine abnormalities.
In October 2020, we presented pre-clinical data from our LVV-based program targeting IMO, RP-L401, at the ESID 2020 Meeting. Preclinical data on IMO indicate that a modest level of engraftment can correct the disease phenotype in vivo, with increased long-term survival, tooth eruption, weight gain and normalized bone resorption. A comprehensive review of pre-clinical gene therapy investigations in TCIRG1-mediated osteopetrosis published in December 2020 supports acceleration into clinical development for RP-L401.
A clinical trial for RP-L401 was initiated in the fourth quarter of 2020 and recruitment is currently ongoing. On November 12, 2020, the CIRM awarded Rocket up to $3.7 million under a CLIN2 grant award to support the clinical development of its lentiviral vector (LVV)-based gene therapy, RP-L401, for the treatment of IMO.
We expect to report initial Phase 1 clinical trial data for our IMO program in the third quarter of 2021.young adulthood.
Strategy
We seek to bring hope and relief to patients with devastating, undertreated, rare pediatric diseases through the development and commercialization of potentially curative first-in-class gene therapies. To achieve these objectives, we intend to develop into a fully-integrated biotechnology company. In the near- and medium-term, we intend to develop our first-in-class product candidates, which are targeting devastating diseases with substantial unmet need, develop proprietary in-house analytics and manufacturing capabilities and continue to commence registration trials for our currently planned programs. In the medium and long-term, we expect to submit our first biologics license applications (“BLAs”) and establish our gene therapy platform and expand our pipeline to target additional indications that we believe to be potentially compatible with our gene therapy technologies. In addition, during that time, we believe that our currently planned programs will become eligible for priority review vouchers from the FDA that provide for expedited review. We have assembled a leadership and research team with expertise in cell and gene therapy, rare disease drug development and product approval.
We believe that our competitive advantage lies in our disease-based selection approach, a rigorous process with defined criteria to identify target diseases. We believe that this approach to asset development differentiates us as a gene therapy company and potentially provides us with a first-mover advantage.
Financial Overview
Since our inception, we have devoted substantially all of our resources to organizing and staffing the company, business planning, raising capital, acquiring or discovering product candidates and securing related intellectual property rights, conducting discovery, research and developmentR&D activities for the programsour product candidates and planning for potential commercialization. We do not have any products approved for sale and have not generated any revenue from product sales. From inception through March 31, 2021,2022, we raised net cash proceeds of approximately $654.1$680.5 million from investors through both equity and convertible debt financing to fund operating activities. As of March 31, 2021, we had cash, cash equivalents and investments of $466.4 million.
Since inception, we have incurred significant operating losses. Our ability to generate product revenue sufficient to achieve profitability will depend heavily on the successful development and eventual commercialization of one or more of the current or future product candidates and programs. We had net losses of $40.2 million for the three months ended March 31, 2021 and $139.7 million for the year ended December 31, 2020. As of March 31, 2021, we had an accumulated deficit of $363.0 million. We expect to continue to incur significant expenses and higher operating losses for the foreseeable future as we advance our current product candidates from discovery through preclinical development and clinical trials and seek regulatory approval of our product candidates. In addition, if we obtain marketing approval for any of our product candidates, we expect to incur significant commercialization expenses related to product manufacturing, marketing, sales and distribution. Furthermore, we expect to incur additional costs as a public company as we transition out of emerging growth company status. Accordingly, we will need additional financing to support continuing operations and potential acquisitions of licensing or other rights for product candidates.
Until such a time as we can generate significant revenue from product sales, if ever, we will seek to fund our operations through public or private equity or debt financings or other sources, which may include collaborations with third parties and government programs or grants. Adequate additional financing may not be available to us on acceptable terms, or at all. We can make no assurances that we will be able to raise the cash needed to fund our operations and, if we fail to raise capital when needed, we may have to significantly delay, scale back or discontinue the development and commercialization of one or more product candidates or delay pursuit of potential in-licenses or acquisitions.
Because of the numerous risks and uncertainties associated with product development, we are unable to predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability. Even if we are able to generate product sales, we may not become profitable. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and be forced to reduce or terminate our operations.
Revenue
To date, we have not generated any revenue from any sources, including from product sales, and we do not expect to generate any revenue from the sale of products in the near future. If our development efforts for product candidates are successful and result in regulatory approval or license agreements with third parties, we may generate revenue in the future from product sales.
Operating Expenses
Research and Development Expenses
Our R&D program expenses consist primarily of external costs incurred for the development of our product candidates. These expenses include:
expenses incurred under agreements with research institutions and consultants that conduct R&D activities including process development, preclinical, and clinical activities on our behalf;
costs related to process development, production of preclinical and clinical materials, including fees paid to contract manufacturers and manufacturing input costs for use in internal manufacturing processes;
consultants supporting process development and regulatory activities;
costs related to in-licensing of rights to develop and commercialize our product candidate portfolio.
We recognize external development costs based on contractual payment schedules aligned with program activities, invoices for work incurred, and milestones which correspond with costs incurred by the third parties. Nonrefundable advance payments for goods or services to be received in the future for use in R&D activities are recorded as prepaid expenses.
Our direct R&D expenses are tracked on a program-by-program basis for product candidates and consist primarily of external costs, such as research collaborations and third-party manufacturing agreements associated with our preclinical research, process development, manufacturing, and clinical development activities. Our direct R&D expenses by program also include fees incurred under license agreements. Our personnel, non-program and unallocated program expenses include costs associated with activities performed by our internal R&D organization and generally benefit multiple programs. These costs are not separately allocated by product candidate and consist primarily of:
salaries and personnel-related costs, including benefits, travel, and stock-based compensation, for our scientific personnel performing R&D activities;
facilities and other expenses, which include expenses for rent and maintenance of facilities, and depreciation expense; and
laboratory supplies and equipment used for internal R&D activities.
Our R&D activities are central to our business model. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development. As a result, we expect thatdirect R&D expenses will increase substantially over the next several yearsconsist principally of external costs, such as we increase personnelfees paid to investigators, consultants, laboratories and CROs in connection with our clinical studies, and costs includingrelated to acquiring and manufacturing clinical study materials. We allocate salary and benefit costs directly related to specific programs. We do not allocate personnel-related discretionary bonus or stock-based compensation support ongoing clinical studies, seek to achieve proof-of-concept in additional product candidates, advance preclinical programs to clinical programs,costs, costs associated with our general discovery platform improvements, depreciation or other indirect costs that are deployed across multiple projects under development and, prepare regulatory filings for product candidates.as such, the costs are separately classified as other R&D expenses.
The following table presents R&D expenses tracked on a program-by-program basis as well as by type and nature of Contentsexpense for the three months ended March 31, 2022 and 2021.

(1) Effective December 2021, a decision was made to no longer pursue Rocket-sponsored clinical evaluation of RP-L401; this program was returned to academic innovators.
We cannot determine with certainty the duration and costs to complete current or future clinical studies of product candidates or if, when, or to what extent we will generate revenues from the commercialization and sale of any of itsour product candidates that obtain regulatory approval. We may never succeed in achieving regulatory approval for any of our product candidates. The duration, costs, and timing of clinical studies and development of product candidates will depend on a variety of factors, including:
the scope, rate of progress, and expense of ongoing as well as any clinical studies and other R&D activities that we undertake;
future clinical study results;
uncertainties in clinical study enrollment rates;
changing standards for regulatory approval; and
the timing and receipt of any regulatory approvals.
We expect R&D expenses to increase for the foreseeable future as we continue to invest in R&D activities related to developing product candidates, including investments in manufacturing, as our programs advance into later stages of development and as we conduct additional clinical trials. The process of conducting the necessary clinical research to obtain regulatory approval is costly and time-consuming, and the successful development of product candidates is highly uncertain. As a result, we are unable to determine the duration and completion costs of R&D projects or when and to what extent we will generate revenue from the commercialization and sale of any of our product candidates.
Our future R&D expenses will depend on the clinical success of our product candidates, as well as ongoing assessments of the commercial potential of such product candidates. In addition, we cannot forecast with any degree of certainty which product candidates may be subject to future collaborations, when such arrangements will be secured, if at all, and to what degree such arrangements would affect our development plans and capital requirements. We expect our R&D expenses to increase in future periods for the foreseeable future as we seek to further development of our product candidates.
The successful development and commercialization of our product candidates is highly uncertain. This is due to the numerous risks and uncertainties associated with product development and commercialization, including the uncertainty of:
the scope, progress, outcome and costs of our clinical trials and other R&D activities;
the efficacy and potential advantages of our product candidates compared to alternative treatments, including any standard of care;
the market acceptance of our product candidates;
obtaining, maintaining, defending, and enforcing patent claims and other intellectual property rights;
significant and changing government regulation; and
the timing, receipt, and terms of any marketing approvals.
A change in the outcome of any of these variables with respect to the development of our product candidates that we may develop could mean a significant change in the costs and timing associated with the development of our product candidates. For example, if the FDA or another regulatory authority were to require us to conduct clinical trials or other testing beyond those that we currently contemplate for the completion of clinical development of any of our product candidates that we may develop or if we experience significant delays in enrollment in any of our clinical trials, we could be required to expend significant additional financial resources and time on the completion of clinical development of that product candidate.
General and Administrative Expenses
General and administrative expenses consist primarily of salaries and related benefit costs for personnel, including stock-based compensation and travel expenses for our employees in executive, operational, finance, legal, business development, and human resource functions. In addition, other significant general and administrative expenses include professional fees for legal, consulting, investor and public relations, auditing, and tax services as well as other expenses for rent and maintenance of facilities, insurance and other supplies used in general and administrative activities. We expect general and administrative expenses to increase for the foreseeable future due to anticipated increases in headcount to support the continued advancement of our product candidates. We also anticipate that as we continue to operate as a public company with increasing complexity, we will continue to incur increased accounting, audit, legal, regulatory, compliance and director and officer insurance costs as well as investor and public relations expenses.
Interest Expense
Interest expense as offor the three months ended March 31, 20212022, is related to the 2021 Convertible Notes, which mature in August 2021, the 2022 Convertible Notes, which were converted into common stock in April 2021, as well as theour financing lease obligation for the Cranbury, NJ facility. Interest expense for the three months ended March 31, 2021, related to the Convertible Notes and our financing lease obligation for the Cranbury, NJ facility.
Interest Income
Interest income is related to interest earned from investments and cash equivalents.

Liquidity, Capital Resources and Plan of Operations
Since inception, weWe have not generated any revenue from any sources, including from product sales, and have incurred losses since inception. Operations of the Company are subject to certain risks and uncertainties, including, among others, uncertainty of drug candidate development, technological uncertainty, uncertainty regarding patents and proprietary rights, having no commercial manufacturing experience, marketing or sales capability or experience, dependency on key personnel, compliance with government regulations and the need to obtain additional financing. Drug candidates currently under development will require significant operatingadditional R&D efforts, including extensive preclinical and clinical testing and regulatory approval, prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel infrastructure and extensive compliance-reporting capabilities.
Our drug candidates are in the development and clinical stage. There can be no assurance that our R&D will be successfully completed, that adequate protection for our intellectual property will be obtained, that any products developed will obtain necessary government approval or that any approved products will be commercially viable. Even if our product development efforts are successful, it is uncertain when, if ever, we will generate significant revenue from product sales. We operate in an environment of rapid change in technology and substantial competition from pharmaceutical and biotechnology companies.
Our consolidated financial statements have been prepared on the basis of continuity of operations, realization of assets and the satisfaction of liabilities in the ordinary course of business. Rocket has incurred net losses and negative cash flows from its operations each year since inception. We had net losses of $42.9 million for the three months ended March 31, 2022, and $169.1 million for the year ended December 31, 2021. As of March 31, 2022 and December 31, 2021, we had an accumulated deficit of $534.9 million and $491.9 million, respectively. As of March 31, 2022, we had $346.6 million of cash, cash equivalents and investments. We expect such resources would be sufficient to fund our operations.operating expenses and capital expenditure requirements into the first half of 2024. We have funded our operations to date primarily with proceeds fromthrough the sale of preferred shares,our equity and debt securities.
In the longer term, our future viability is dependent on our ability to generate cash from operating activities or to raise additional capital to finance our operations. If we raise additional funds by issuing equity securities, our stockholders will experience dilution. Any future debt financing into which we enter may impose upon us additional covenants that restrict our operations, including limitations on our ability to incur liens or additional debt, pay dividends, repurchase our common stock, make certain investments and the issuance of convertible notes.engage in certain merger, consolidation, or asset sale transactions. Any debt financing or additional equity that we raise may contain terms that are not favorable to us or our stockholders. Our failure to raise capital as and when needed could have a negative impact on our financial condition and ability to pursue our business strategies.

During the three months ended March 31, 2020, net cash used by financing activities was $0.1 million, consisting of refinancing costs paid to lenders related to the convertible notes exchange.
Funding Requirements
We expect expenses to increase substantially in connection with our ongoing activities, particularly as we advance our preclinical activities, and initiate additional clinical trials and manufacturing of our product candidates. In addition, we expect to incur additional costs associated with operating as a public company as we transition from being an emerging growth company. Our expenses will also increase as we:
leverage our programs to advance other product candidates into preclinical and clinical development;
seek regulatory agreements to initiate clinical trials in the Europe, US and ROW;
establish a sales, marketing, medical affairs and distribution infrastructure to commercialize any product candidates for which Rocket may obtain marketing approval and intend to commercialize on its own or jointly;
hire additional preclinical, clinical, regulatory, quality and scientific personnel;
expand our operational, financial and management systems and increase personnel, including personnel to support our clinical development, manufacturing and commercialization efforts and our operations as a public company;
maintain, expand and protect our intellectual property portfolio; and
acquire or in-license other product candidates and technologies.
As of March 31, 2021, we had cash, cash equivalents and investments of $466.4 million. We expect such resources would be sufficient to fund our operating expenses and capital expenditure requirements into the second half of 2023.
Because of the numerous risks and uncertainties associated with research, development and commercialization of pharmaceutical product candidates, we are unable to estimate the exact amount of working capital requirements. Our future funding requirements will depend on, and could increase significantly as a result of, many factors, including:
the scope, progress, results and costs of researching and developing our product candidates, and conducting preclinical studies and clinical trials;
the costs, timing and outcome of regulatory review of our product candidates;
the costs of future activities, including product sales, medical affairs, marketing, manufacturing and distribution, for any of our product candidates for which we receive marketing approval;
the costs of manufacturing commercial-grade product to support commercial launch;
the ability to receive additional non-dilutive funding, including grants from organizations and foundations;
the revenue, if any, received from commercial sale of its products, should any of its product candidates receive marketing approval;
the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims;
our ability to establish and maintain collaborations on favorable terms, if at all;
the extent to which we acquire or in-license other product candidates and technologies; and
the timing, receipt and amount of sales of, or milestone payments related to our royalties on, current or future product candidates, if any.
Until such time, if ever, as we can generate substantial product revenue, we expect to finance our cash needs through a combination of public or private equity offerings, debt financings, collaborations, strategic partnerships or marketing, distribution or licensing arrangements with third parties. To the extent that we raise additional capital through the sale of equity or convertible debt securities, our ownership interest may be materially diluted, and the terms of such securities could include liquidation or other preferences that adversely affect the rights of our common stockholders. Debt financing and preferred equity financing, if available, may involve agreements that include restrictive covenants that limit our ability to take specified actions, such as incurring additional debt, making capital expenditures or declaring dividends. In addition, additional debt financing would result in increased fixed payment obligations.
If we raise funds through governmental funding, collaborations, strategic partnerships or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, reduce or eliminate our product development or future commercialization efforts or grant rights to develop and market product candidates that it would otherwise prefer to develop and market themselves.
Contractual Obligations and Commitments
There were no material changes outside the ordinary course of our business to the contractual obligations specified in the table of contractual obligations included in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 20202021 Form 10-K. Information regarding contractual obligations and commitments may be found in Note 1110 of our Consolidated Unaudited Financial Statementsunaudited consolidated condensed financial statements in this Quarterly Report on Form 10-Q.
Off-Balance Sheet Arrangements
We did not have during the periods presented, and do not currently have any off-balance sheet arrangements as defined in the rules and regulationsthat are material or reasonably likely to become material to our financial condition or results of the Securities and Exchange Commission.operations.
Recently Issued Accounting Pronouncements
A description of recently issued accounting pronouncements that may potentially impact our financial position and results of operations is disclosed in Note 3 of our “Consolidated Unaudited Financial Statements,”unaudited consolidated condensed financial statements in this Quarterly Report on Form 10-Q.
Item 3 | Quantitative and Qualitative Disclosures About Market Risk |
We are exposed to market risks in the ordinary course of our business. These market risks are principally limited to interest rate fluctuations. We had cash, cash equivalents and investments of $466.4 million at March 31, 2021, consisting primarily of funds in a money market account, corporate and municipal bonds and United States Treasury securities. The primary objective of our investment activities is to preserve principal and liquidity while maximizing income without significantly increasing risk. We do not enter into investments for trading or speculative purposes. Due to the short-term nature of our investment portfolio, we do not believe an immediate 1.0% increase in interest rates would have a material effect on the fair market value of our portfolio, and accordingly we do not expect a sudden change in market interest rates to affect materially our operating results or cash flows.Not Applicable
Our 2021 Convertible Notes and 2022 Convertible Notes bear interest at a fixed rate and therefore a change in interest rates would not impact the amount of interest we would have to pay on this indebtedness.
Item 4 | Controls and Procedures |
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our principal executive officer and our principal financial officer, evaluated, as of the end of the period covered by this Quarterly Report on Form 10-Q, the effectiveness of our disclosure controls and procedures. Based on that evaluation of our disclosure controls and procedures as of March 31, 2021,2022, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures as of such date are effective at the reasonable assurance level. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act are recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act 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. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and our management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
Inherent Limitations of Internal Controls
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
Changes in Internal Control over Financial Reporting
There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended March 31, 2021,2022, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
