Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Organization and basis of presentation | 1. Organization and basis of presentation Candel Therapeutics, Inc., formerly known as Advantagene, Inc. (the “Company”) is a late clinical stage biotechnology company that was incorporated in Delaware in June 2003. On November 30, 2020, the Company changed its name to Candel Therapeutics, Inc. The Company is focused on helping patients fight cancer with oncolytic viral immunotherapies. The Company’s engineered viruses are designed to induce immunogenic cell death through direct viral – mediated cytotoxicity in cancer cells, thus releasing tumor neo-antigens and creating a pro-inflammatory microenvironment at the site of injection. The Company has established two oncolytic viral immunotherapy platforms and its two product candidates, CAN-2409 and CAN-3110, are in clinical trials for a number of tumor types. The Company is subject to risks and uncertainties common to early-stage companies in the biotechnology industry, including, but not limited to, development by competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with government regulations and the ability to secure additional capital to fund operations. Product candidates currently under development will require significant additional research and development efforts, including preclinical and clinical testing and regulatory approval, prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel and infrastructure and extensive compliance-reporting capabilities. Even if the Company’s product development efforts are successful, it is uncertain when, if ever, the Company will realize revenue from product sales. The Company has funded its operations primarily with proceeds from the sale of its capital stock and convertible notes. The Company has incurred recurring losses since its inception, including a net loss of $ 5.0 million and $ 21.6 million for the six months ended June 30, 2022 and 2021, respectively. In addition, as of June 30, 2022, the Company had an accumulated deficit of $ 85.3 million. The Company expects to continue to generate operating losses for the foreseeable future. On July 29, 2021, the Company completed its initial public offering of common stock, or the IPO, at which time the Company issued 9,000,000 shares of its common stock at a price to the public of $ 8.00 per share, and on August 13, 2021, the Company issued an additional 887,994 shares of common stock at $ 8.00 per share as a partial exercise of the underwriters’ option to purchase additional shares, resulting in net proceeds to the Company of $ 71,335 , after deducting underwriting discounts and commissions and offering expenses. Upon closing of the IPO, all outstanding shares of the Company’s convertible preferred stock automatically converted into 7,066,398 shares of common stock. The future viability of the Company is dependent on its ability to raise additional capital to finance its operations. The Company’s inability to raise capital as and when needed could have a negative impact on its financial condition and ability to pursue its business strategies. There can be no assurances that additional funding will be available on terms acceptable to the Company, or at all. The Company believes that existing resources will fund planned operations for at least 12 months from the date that these condensed consolidated financial statements were available to be issued. Accordingly, the condensed consolidated financial statements have been prepared on a basis that assumes the Company continue as a going concern and contemplates the realization of assets and satisfaction of liabilities and commitments in the ordinary course of business. |

Accounting Policies [Abstract] | |
Summary of significant accounting policies | 2. Summary of significant accounting policies Basis of presentation The accompanying condensed consolidated financial statements have been prepared in accordance with accounting standards set by the Financial Accounting Standards Board ("FASB"). The FASB sets generally accepted accounting principles ("GAAP") that the Company follows to ensure its financial condition, results of operations, and cash flows are consistently reported. References to GAAP issued by the FASB in these notes to the financial statements are to the FASB Accounting Standards Codification ("ASC") . Principles of consolidation The condensed consolidated financial statements include the accounts of Candel Therapeutics, Inc. and its wholly owned subsidiary Candel Therapeutics Securities Corporation. All intercompany transactions and balances have been eliminated. Segment Information Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision-maker in deciding how to allocate resources and assess performance. The Company and the Company's chief operating decision maker, the Company's chief executive officer, views the Company's operations and manages its business as a single operating segment. The Company only operates in the United States. Emerging growth company The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the “Jobs Act”). Under the Jobs Act emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the Jobs Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that is (i) no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the Jobs Act. As a result, these consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. Unaudited Interim Financial Information The accompanying condensed consolidated balance sheet as of June 30, 2022, the condensed consolidated statements of operations for the three and six months ended June 30, 2022 and 2021, the condensed consolidated statements of stockholders’ equity (deficit) for the three and six months ended June 30, 2022 and 2021, the condensed consolidated statements of cash flows for the six months ended June 30, 2022 and 2021, and the related interim disclosures are unaudited. These unaudited condensed consolidated financial statements include all adjustments necessary, consisting of only normal recurring adjustments, to fairly state the financial position and the results of the Company’s operations and cash flows for interim periods in accordance with U.S. GAAP. Interim period results are not necessarily indicative of results of operations or cash flows for a full year or any subsequent interim period. The accompanying condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto for the year ended December 31, 2021 included in the Company’s Annual Report on Form 10-K ("Form 10-K") on file with the SEC. Use of estimates The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and related disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting period. On an ongoing basis, the Company’s management evaluates its estimates, which include but are not limited to management’s judgments of accrued expenses, valuation of stock-based option awards, valuations of warrants, and income taxes. Actual results could differ from those estimates. Prior to the IPO, the Company utilized significant estimates and assumptions in determining the fair value of its common stock. The Company has utilized various valuation methodologies in accordance with the framework of the American Institute of Certified Public Accountants Technical Practice Aid, Valuation of Privately-Held Company Equity Securities Issued as Compensation (the "Practice Aid"), to estimate the fair value of its common stock and warrants. Each valuation methodology includes estimates and assumptions that require the Company’s judgment. These estimates and assumptions include a number of objective and subjective factors, including external market conditions, the prices at which the Company sold shares of preferred stock, the superior rights and preferences of securities senior to the Company’s common stock at the time of, and the likelihood of, achieving a liquidity event, such as an initial public offering or sale. Significant changes to the key assumptions used in the valuations could result in different fair values of common stock at each valuation date. Cash and cash equivalents The Company considers all highly liquid investments purchased with original final maturities of 90 days or less from the date of purchase to be cash equivalents. Cash and cash equivalents comprise marketable securities with maturities of less than 90 days when purchased. Cash equivalents are reported at fair value. Restricted cash The Company has $ 266 and $ 424 of restricted cash as of June 30, 2022 and December 31, 2021 , respectively, which represents cash held in a restricted bank account under the terms of the Company’s Needham, Massachusetts facility lease and at December 31, 2021, as security for the Company credit card. Fair value measurements Certain assets and liabilities of the Company are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable: ▪ Level 1—Quoted prices in active markets for identical assets or liabilities. ▪ Level 2—Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data. ▪ Level 3—Unobservable inputs that are supported by little or no market activity that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques. The carrying values of cash and cash equivalents, accounts payable, and accrued expenses approximate their fair values due to the short-term nature of these assets and liabilities. The Company’s warrant liability is carried at fair value and is classified as Level 3 measurement. Property and equipment Property and equipment consist of lab and manufacturing equipment, networking and computer equipment, furniture and fixtures and leasehold improvements. Property and equipment are recorded at cost, and depreciated using the straight-line method over the estimated useful lives of the respective assets: ASSET ESTIMATED USEFUL LIFE Networking and computer equipment 5 years Laboratory equipment 5 years Manufacturing equipment 5 years Furniture and fixtures 5 years Leasehold improvements Shorter of the useful life or remaining lease term Leases The Company adopted ASC 842 as of January 1, 2022 and elected the transition method under ASU 2016-02 whereby the Company records a right-of-use asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. The Company also elected to apply the practical expedients intended to ease transition. Accordingly, the Company has only applied ASC 842 to leases existing as of January 1, 2022. The Company determines if an arrangement is, or contains, a lease at inception. Lease right of use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Lease right of use assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments to be made over the lease term. The lease right of use asset is equal to the lease liability and adjusted for prepaid rent, initial direct costs, and incentives. As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating lease expense is recognized on a straight-line basis over the lease term. The Company has elected to not apply the recognition requirements of ASC 842 for short-term leases, which is defined as a lease that, at the lease commencement date, has a lease term of 12 months or less and does not include an option to purchase the underlying asset that the Company is reasonably certain to exercise. For real estate lease agreements entered into or modified after the adoption of ASC 842 that include lease and non-lease components, the Company has elected to account for the lease and non-lease components, such as common area maintenance charges, as a single lease component term. Concentrations of credit risk Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents and marketable securities. Periodically, the Company maintains deposits and investments in accredited financial institutions in-excess of the federally insured limits. The Company deposits its cash in financial institutions with a high credit quality and has not experienced any losses on such accounts and does not believe it is exposed to any unusual credit risk beyond the normal risk associated with commercial banking relationships. Impairment of long-lived assets Long-lived assets to be held and used are tested for recoverability whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. Factors that the Company considers in deciding when to perform an impairment review include significant underperformance of the business in relation to expectations, significant negative industry or economic trends and significant changes or planned changes in the use of the assets. If an impairment review is performed to evaluate a long-lived asset group for recoverability, the Company compares forecasts of undiscounted cash flows expected to result from the use and eventual disposition of the long-lived asset group to its carrying value. An impairment loss would be recognized when estimated undiscounted future cash flows expected to result from the use of an asset group are less than its carrying amount. The impairment loss would be based on the excess of the carrying value of the impaired asset group over its fair value, determined based on discounted cash flows. Long-lived assets consist of fixed assets and operating lease assets. In the fourth quarter of 2021, the Company recorded an impairment charge of approximately $ 553 related to manufacturing equipment that the Company does not plan to use for its intended use and recorded a reserve to reduce the carrying value to its estimated realizable value. The Company has not recorded any additional impairment losses on such long-lived assets . Revenue recognition The Company applies Accounting Standards Codification, or ASC, Topic 606, Revenue from Contracts with Customers, (ASC 606). This standard applies to all contracts with customers, except for contracts that are within the scope of other standards, such as leases, insurance, collaboration arrangements and financial instruments. Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations, and then assesses whether or not each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied . Research and development costs and accruals Research and development expenses include salaries and benefits, materials and supplies, preclinical and clinical trial expenses, stock-based compensation expense, depreciation of equipment, contract services and other outside expenses. The Company has entered into various research and development-related contracts with clinical and research institutions, contract research organizations, and other companies. These agreements are generally cancelable, and related payments are recorded as research and development expenses as incurred. Costs of certain development activities, such as manufacturing, pre-clinical and clinical trial expenses, are recognized based on an evaluation of the progress to completion of specific tasks. Payments for these activities are based on the terms of the individual arrangements, which may differ from the pattern of costs incurred, and are reflected in the financial statements as prepaid or accrued research and development costs. Nonrefundable advance payments for goods or services to be received in the future for use in research and development activities are deferred and capitalized. The capitalized amounts are expensed as the related goods are delivered or the services are performed. Costs incurred in obtaining technology licenses and intellectual property are charged to research and development expenses as acquired in-process research and development if the technology licensed or intellectual property acquired has not reached technological feasibility and has no alternative future use. Patent costs All patent-related costs incurred in connection with preparing, filing, maintaining and prosecuting patent applications are expensed as incurred due to the uncertainty about the recovery of the expenditure. Amounts incurred are classified in general and administrative expenses. Stock-based compensation The Company accounts for its stock-based compensation in accordance with ASC Topic 718, Compensation—Stock Compensation (ASC 718). ASC 718 requires all share-based payments to employees and directors to be recognized as expense in the consolidated statements of operations based on their grant date fair values. In addition, in accordance with FASB Accounting Standards Update ("ASU") 2016-09 which identifies areas for simplification of several areas of share-based payment transactions, the Company treats non-employee grants the same as employee grants. The Company estimates the fair value of options granted using the Black-Scholes option pricing model for stock option grants to both employees and non-employees. The Company believes the fair value of the stock options granted to non-employees is more reliably determinable than the fair value of the services provided. The Black-Scholes option pricing model requires inputs based on certain subjective assumptions, including (a) the expected stock price volatility, (b) the expected term of the award, (c) the risk-free interest rate and (d) expected dividends. Due to a lack of company-specific historical and implied volatility data, the Company has based its computation of expected volatility on the historical volatility of a representative group of public companies with similar characteristics to the Company, including stage of product development and life science industry focus. The historical volatility is calculated based on a period of time commensurate with the expected term assumption. The Company uses the simplified method as prescribed by the SEC Staff Accounting Bulletin No. 107, Share-Based Payment, to calculate the expected term for options granted to employees as it does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term. The expected term is applied to the stock option grant group as a whole, as the Company does not expect substantially different exercise or post-vesting termination behavior among its employee population. For options granted to non-employees, the Company utilizes the contractual term of the share-based payment as the basis for the expected term assumption. The risk-free interest rate is based on a treasury instrument whose term is consistent with the expected term of the stock options. The expected dividend yield is assumed to be zero as the Company has never paid dividends and has no current plans to pay any dividends on its common stock. Prior to the IPO, there were significant judgments and estimates inherent in the determination of the fair value of the Company’s common stock. These estimates and assumptions included a number of objective and subjective factors, including external market conditions, the prices at which the Company sold shares of preferred stock, the superior rights and preferences of securities senior to its common stock at the time of, and the likelihood of, achieving a liquidity event, such as an initial public offering or sale. The Company generally expenses the fair value of its share-based compensation awards to employees and non-employees on a straight-line basis over the requisite service period, which is generally the vesting period. Government grants The Company has applied for grants for the reimbursement of expenditures with the National Institutes of Health ("NIH") for certain qualified operating expenditures. The Company recognizes government grants when there is reasonable assurance that the Company will comply with the conditions attached to the grant arrangement and the grant will be received. Government grants for research and development efforts are reco rded as grant income and classified in other income in the statements of operations. The Company had no government grant revenue in 2022 and recognized government grant revenue of $ 605 and $ 796 for t he three and six months ended June 30, 2021. Grant income is recognized as a component of other income/(expense), net in the condensed consolidated statements of operations . The Company's grant with the NIH was completed at the end of 2021. Income taxes The Company accounts for income taxes using the asset and liability method in accordance with ASC Topic 740, Income Taxes (ASC 740) which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the financial statements or in the Company’s tax returns. Deferred tax assets and liabilities are determined on the basis of the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Changes in deferred tax assets and liabilities are recorded in the provision for income taxes. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent it believes, based upon the weight of available evidence, that it is more likely than not that all or a portion of the deferred tax assets will not be realized, a valuation allowance is established through a charge to income tax expense. Potential for recovery of deferred tax assets is evaluated by estimating the future taxable profits expected and considering prudent and feasible tax planning strategies. At June 30, 2022 and December 31, 2021, the Company has concluded that a full valuation allowance is necessary for its deferred tax assets (see Note 12). The Company accounts for uncertainty in income taxes by applying the two-step process to determine the amount of tax benefit to be recognized in the financial statements. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination by the taxing authorities. If the tax position is deemed more-likely-than-not to be sustained, the tax is then assessed as the amount of benefits to be recognized in the consolidated financial statements. The amount of benefits that may be used are the largest amounts that have a greater than 50 % likelihood of being realized upon ultimate settlement. The provision for income taxes includes the effects of any resulting tax reserves or unrecognized tax benefits that are considered appropriate, as well as the related net interest and received. Net loss per share Basic net loss per share is computed by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed using the weighted-average number of shares of common stock outstanding during the period and, if dilutive, the weighted-average number of potential shares of common stock. Diluted net loss per share is the same as basic net loss per share for the three and six months ended June 30, 2022 and 2021 since all potential shares of common stock instruments are anti-dilutive as a result of the loss for such periods. The Company’s convertible preferred stock contractually entitles the holders of such shares to participate in dividends but does not contractually require the holders of such shares to participate in losses of the Company. Accordingly, in periods in which the Company reports a net loss, such losses are not allocated to such participating securities. In periods where the Company reports a net loss attributable to common stockholders, diluted net loss per share is the same as basic net loss per share, since dilutive shares of common stock are not assumed to have been issued if their effect is anti-dilutive. The Company reported a net loss attributable to common stockholders for the three and six months ended June 30, 2022 and 2021 . Recently adopted accounting standards In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”) , as amended by various subsequently issued ASUs. The standard requires lessees to recognize an operating lease with a term greater than one year on their balance sheets as a right-of-use asset and corresponding lease liability, measured at the present value of the lease payments. Lessees are required to classify leases as either finance or operating leases. If the lease is effectively a financed purchase by the lessee, it is classified as a financing lease, otherwise it is classified as an operating lease. This classification will determine the pattern of recognition of lease cost on our condensed and consolidated statement of operations over the term of the lease. In July 2018, the FASB also issued ASU 2018-11, Leases (Topic 842): Targeted Improvements (“ASU 2018-11”) , which permits entities to continue applying legacy guidance in ASC 840, Leases, including its disclosure requirements, in the comparative periods presented in the year that the entity adopts the new leasing standard. The Company elected the package of practical expedients permitted under the transition guidance within the standard. Accordingly, the Company did not reassess the conclusion of whether the existing arrangements contain a lease, lease classification and initial direct costs under ASC 842. In June 2020, the FASB also issued ASU 2020-05, Revenue from contracts with customers (Topic 606) and Leases (Topic 842): effective dates for certain entities, which deferred the effective date certain entities were required to adopt ASC 842. The update extended the effective date for adoption of ASC 842 until fiscal years beginning after December 15, 2021. As an emerging growth company we were not required to adopt ASC 842 until January 1, 2022. The Company adopted the standard on January 1, 2022 using the effective date method. As such, the condensed consolidated balance sheets and statements of operations for prior periods will not be comparable in the year of adoption of ASC 842. As a result of the adoption of ASC 842, the Company recorded a lease right of use asset of $ 1,264 and a lease liability of $ 2,368 on the condensed consolidated balance sheets as of January 1, 2022 related to an operating lease. The Company derecognized deferred rent liabilities, which makes up the difference between the lease right of use asset and lease liability. The adoption of the standard did not have a material impact on the Company’s condensed consolidated statement of operations or condensed consolidated statement of cash flows. In August 2020, the FASB issued ASU 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40 ). The guidance simplifies the complexity associated with applying U.S. GAAP for certain financial instruments with characteristics of liabilities and equity. This ASU (1) simplifies the accounting for convertible debt instruments and convertible preferred stock by removing guidance in ASC 470-20, Debt: Debt with Conversion and Other Options , that requires entities to account for beneficial conversion features and cash conversion features in equity, separately from the host convertible debt or preferred stock; (2) revises the scope exception from derivative accounting in ASC 815-40 for freestanding financial instruments and embedded features that are both indexed to the issuers own stock and classified in stockholders' equity, by removing certain criteria required for equity classification; and (3) revises the guidance in ASC 260, Earnings Per Share , to require entities to calculate diluted earnings per share for convertible instruments by using the if-converted method. As an emerging growth company, we are not required to adopt ASU 2020-06 until January 1, 2024, however early adoption is permitted. The Company elected to early adopt the standard on January 1, 2022 and upon adoption, there was no impact to our condensed consolidated statement of operations and cash flows and our basic and diluted net loss per share amounts. In November 2021, the FASB issued ASU 2021-10, which created Topic 832, Government Assistance, which requires business entities to disclose information about certain government assistance they receive. The ASU requires qualitative and quantitative disclosures around the nature of transactions and related accounting policy used, the line items on the balance sheet and income statement that are affected, and the significant terms and conditions of the transactions. The ASU is effective for fiscal years beginning after December 15, 2021 . The Company believes its historical disclosure already met the requirements of the new standard. As such, no changes or additional disclosure was determined to be necessary . |

Fair value of financial assets and liabilities | 3. Fair value of financial assets and liabilities The following tables present information about the Company’s financial assets and liabilities measured at fair value on a recurring basis and indicate the level of the fair value hierarchy utilized to determine s uch fair values: FAIR VALUE MEASUREMENTS AS OF LEVEL 1 LEVEL 2 LEVEL 3 TOTAL Liabilities: Warrant liability — — 4,996 4,996 Total $ — $ — $ 4,996 $ 4,996 FAIR VALUE MEASUREMENTS AS OF LEVEL 1 LEVEL 2 LEVEL 3 TOTAL Liabilities: Warrant liability — — 18,252 18,252 Total $ — $ — $ 18,252 $ 18,252 Valuation of warrant liability In connection with the November 13, 2018 issuance of Series B convertible preferred stock, the Company issued warrants to purchase shares of common stock of which certain warrants are shown as a liability on the balance sheet, see Note 10. The fair value of the warrant liability was determined based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The fair value of the warrant liability uses various valuation methods, including the Monte Carlo method, the option-pricing method, probability-weighted expected return and the hybrid method, all of which incorporate assumptions and estimates, to value the common stock warrants. The hybrid method is often used when a company is expecting a liquidity event in the near future and is a combination of the option-pricing and probability-weighted expected return methods. Estimates and assumptions impacting the fair value measurement include the fair value per share of the underlying shares of common stock, risk-free interest rate, expected dividend yield, expected volatility of the price of the underlying common stock, and the remaining contractual term of the warrants. The most significant assumption in the model impacting the fair value of the common stock warrants is the fair value of the Company’s common stock as of each remeasurement date. Prior to the IPO, the Company determined the fair value per share of the underlying common stock by taking into consideration the most recent sales of preferred stock, results obtained from third-party valuations and additional factors that are deemed relevant. The following table provides a roll forward of the aggregate fair values of the Company’s warrant liability, for which fair value is determined by Level 3 inputs: SERIES B Balance at December 31, 2021 $ 18,252 Change in fair value ( 13,256 ) Balance at June 30, 2022 $ 4,996 |

Term Loan payable to a Bank | 6. Term Loan payable to a Bank On February 24, 2022 , the Company entered into a loan and security agreement (the "Loan Agreement") with Silicon Valley Bank ("SVB") pursuant to which SVB has agreed to provide term loans to the Company in an aggregate principal amount of up to $ 25.0 million. The Company borrowed $ 20.0 million upon entering into the Loan Agreement. The Company can borrow up to an additional aggregate principal amount not to exceed $ 5.0 million, at any time on or prior to December 31, 2022, following the Company having provided evidence to SVB of (a) achievement of positive Phase 2 clinical activity data from the Company’s CAN-2409 NSCLC clinical trial, (b) dosing of its first patient in its Phase 3 CAN-2409 high-grade glioma clinical trial and (c) receipt on or prior to December 31, 2022, of net cash proceeds in an amount equal to at least $ 75.0 million from the issuance and sale of equity securities to investors acceptable to SVB. The term loan is secured by substantially all of the Company’s properties, rights and assets, except for its intellectual property, which is subject to a negative pledge under the Loan Agreement. The term loans bear interest at a floating rate per annum equal to the greater of (A) 5.75 % and (B) the prime rate (as published in the money rates section of The Wall Street Journal) plus 2.50 %. The Company is required to make monthly interest payments, and commencing on February 1, 2024 , 24 consecutive installments of principal plus monthly payments of accrued interest. Upon repayment in full of the term loans, the Company will be required to pay a final payment fee equal to 4.50 % of the original principal amount of any funded term loan being repaid. The Loan Agreement permits voluntary prepayment of all, but not less than all, of the SVB term loans, subject to a prepayment premium of 1 % to 3 % based upon the timing of the repayment. During the three and six months ended June 30, 2022, the Company recorded interest expense relating to the Loan Agreement of $ 412 and $ 561 , respectively. The weighted average effective interest rate as of June 30, 2022 was 8.17 %. The Company incurred $ 90 of debt issuance costs and will incur a $ 900 final payment fee, which were recorded as debt discount and are being amortized over the term of the Loan Agreement.

Other long-term debt Periphagen Note On December 9, 2019, the Company entered into a series of asset purchase agreements with Periphagen, Inc., a biopharmaceutical company focused on the development of gene therapy vectors. Under the terms of the asset purchase agreements, the Company assumed a $ 1,000 promissory note bearing a contractual interest rate of 2 % compounded annually, with the outstanding balance and accrued interest due upon maturity in November 2027 , with no interim installments due. The estimated market rate for the Company for an unsecured loan with a maturity in November 2027 was determined to be 15.83 %. Although the Company does not have a public credit rating, management estimates a CCC credit rating based on the Company’s financial position and stage of development. Using the commensurate rate for a CCC rated company and based on the amount due at maturity, the present value of the future cash outflow was determined to be $ 417 at the transaction date. As of June 30, 2022, the present value of future cash flows outflows is $ 604 . |

In addition, the Company issued to the same stockholder additional five-year warrants for the purchase of 3,672,484 shares of common for $ 6.81 per share which are only exercisable in the event that the Company completes a future financing that meets certain financial milestones or achieves certain share prices (the “Conditional Series B Warrants”). The Series B Warrants and the Conditional Series B Warrants contain provisions allowing cashless exercise. The Company recorded the Series B Warrants as a component of stockholder’s equity at the time of issuance at their estimated fair value of $ 2,124 and recorded the Conditional Series B Warrants as a liability on the condensed consolidated balance sheet as the number of shares used to calculate the settlement is not a fixed number of shares. The Conditional Series B Warrants are remeasured to their fair value at each reporting date with changes in the fair value recognized as a component of other income (expense), net in the condensed consolidated statements of operations. The Company will continue to recognize changes in the fair value of the Conditional Series B Warrants until each Conditional Series B Warrant is exercised, expires or qualifies for equity classification. The warrant liability fair value was $ 4,996 and $ 18,252 as of June 30, 2022 and December 31, 2021, respectively. On June 24, 2021, the Company’s board of directors approved and on July 14, 2021 the stockholders approved, effective upon the closing of the IPO, an amendment to the terms of the Series B Warrant and the Conditional Series B Warrants to extend the expiration date from November 2023 to November 2025 . In addition, the terms of the Conditional Series B Warrants were amended such that in the event the future financing milestones or certain share prices are achieved, the warrants would only be exercisable in conjunction with the sale of the Company or in November 2025 through a cashless exercise. NC Ohio trust warrants On March 20, 2019, the Company established the NC Incorporated Ohio Trust, an irrevocable trust funded by the Company. The beneficiary in the trust agreement has provided past services to the Company for more than 15 years and is a non-employee. The warrant provides the beneficiary the right to purchase 162,740 shares of the Company’s common stock, $ 0.01 par value at an exercise price of $ 1.46 per share, subject to adjustments as specified in the warrant agreement. The arrangement is unknown to the beneficiary as the arrangement is a silent trust. The Company recognizes the warrants as compensation expense within the condensed consolidated statement of operations and when the warrants are granted or at the service inception date if the service inception date precedes the grant date. In the period in which the grant date occurs, cumulative compensation cost shall be adjusted to reflect the cumulative effect of measuring compensation cost based on the fair value at the grant date rather than the fair value previously used at the service inception date or subsequent reporting dates. As of June 30, 2022 and December 31, 2021 , a grant date was not established as there was not a mutual understanding of key terms. The Company remeasures the fair value of the award at each reporting date, as the service date preceded the grant date. The value of the warrants for 162,740 shares of common stock wa s $ 447 and $ 1,069 as of June 30, 2022 and December 31, 2021, respectively, and was recorded as stock compensation expense within research and development expense and a credit to stockholders’ equity in the condensed consolidated financial statements. |

Share-Based Payment Arrangement [Abstract] | |
Stock options, restricted stock and stock—based compensation | 11. Stock options, restricted stock and stock-based compensation The Company’s 2015 Stock Plan, as amended, (the 2015 Plan) provides for the Company to sell or issue common shares or restricted common stock, or to grant incentive stock options or nonqualified stock options for the purchase of common stock, to employees, members of the board of directors and consultants of the Company. The 2015 Plan is administered by the board of directors and exercise prices, vesting and other restrictions are determined at its discretion. All stock option grants are non-statutory stock options except option grants to employees intended to qualify as incentive stock options under the Internal Revenue Code of 1986, as amended. Incentive stock options may not be granted at less than the fair market value of the Company’s common stock on the date of grant, as determined in good faith by the board of directors at its sole discretion. Nonqualified stock options may be granted at an exercise price established by the board of directors at its sole discretion and the vesting periods may vary. Vesting periods are generally four years and are determined by the board of directors. Stock options become exercisable as they vest. Options granted under the 2015 Plan expire no more than ten years from the date of grant. As of June 30, 2022 , there are no shares available for grants under the 2015 Plan and the 2015 Plan continues to govern the terms and conditions of the outstanding awards under the 2015 Plan. On July 14, 2021, the Company’s 2021 Equity Incentive Plan, or the 2021 Plan, was approved by the Company’s stockholders, and became effective upon completion of the IPO and serves as the successor to the 2015 Plan. There a re 2,054,000 shares of common stock reserved for issuance under the 2021 Plan and 1,854,464 shares remained available for grants as of June 30, 2022. Stock option activity is summarized as follows: NUMBER OF WEIGHTED- Outstanding as of December 31, 2021 4,783,333 $ 2.34 Granted 1,222,400 4.23 Cancelled, forfeited or expired ( 30,273 ) 4.19 Exercised ( 324,675 ) 1.46 Outstanding as of June 30, 2022 5,650,785 $ 2.79 Exercisable as of June 30, 2022 2,410,505 $ 2.11 Unvested as of June 30, 2022 3,240,280 $ 3.30 The 2015 Plan, permits participants to use common stock they previously acquired to pay for the exercise of stock options based upon the fair value on the date of exercise. In connection with the exercise of a stock options to purchase 306,518 shares of our common stock at an exercise price of $ 1.46 , option holders tendered 122,608 shares of our common stock previously acquired in consideration of the full aggregate exercise price in accordance with the terms of the option and the 2015 Plan. The shares tendered are recorded as treasury stock within the Company's condensed and consolidated financial statements at June 30, 2022. The fair value of stock options granted was estimated on the grant date using the Black-Scholes option pricing model based on the following weighted-average assumptions: SIX MONTHS ENDED 2022 2021 Expected option life (years) 6.02 - 6.08 5.00 - 6.25 Risk-free interest rate 1.69 % - 3.03 % 0.89 % - 1.12 % Expected volatility 85.09 % - 86.09 % 85.87 % - 89.02 % Expected dividend yield 0 % 0 % Exercise price $ 3.24 - $ 5.19 $ 4.97 - $ 6.64 Fair value of common stock $ 3.24 - $ 5.19 $ 4.97 - $ 6.64 The total intrinsic value of stock options vested during the six months ended June 30, 2022 and 2021 was $ 819 and $ 411 , respectively. Stock-based compensation expense for the three and six months ended June 30, 2022 and 2021 was classified in the condensed consolidated statements of operations as follows: THREE MONTHS ENDED SIX MONTHS ENDED 2022 2021 2022 2021 Research and development $ 57 $ 400 $ 199 $ 516 General and administrative 381 669 730 984 Total stock-based compensation expense $ 438 $ 1,069 $ 929 $ 1,500 As of June 30, 2022 and 202 1, total unrecognized compensation cost related to the unvested stock-based awards was $ 7,332 and $ 6,060 , respectively. As of June 30, 2022 and 2021, t hese amounts are expected to be recognized over a weighted average period of 2.45 and 2.73 years, respectively . |

License Agreement [Abstract] | |
Exclusive licensing agreement with a related party | 13. Exclusive licensing agreement with a related party In March 2014, the Company entered into an exclusive licensing agreement with Ventagen, LLC (“Ventagen”) which provides Ventagen the right to develop products for commercial sale and distribution within Mexico, Belize, Guatemala, Honduras, El Salvador, Costa Rica, Nicaragua, Panama, Colombia, and Bolivia (the "Territory"). Ventagen paid the Company $ 1,000 upon the signing of the agreement and agreed to a fixed future payment to the Company of $ 2,500 . The future payment will be made upon the achievement of $ 5,000 of sales of an approved product by Ventagen and is subject to reduction if Ventagen’s costs to develop an approved product exceeds $ 4,000 . In addition to the upfront payment and the future payment, Ventagen agreed to purchase from the Company all manufactured product that is required for clinical or commercial purposes at a price of cost plus 25 % of the wholesale price of the approved product, subject to a minimum or maximum price. In the event the Company is unable or unwilling to manufacture supply under the terms of the agreement, Ventagen has the right to manufacture its own supply and will be required to pay a fixed fee per dose sold. The Company also agreed to provide certain services to Ventagen related to Ventagen’s development plan. Stockholders of the Company own 49.5 % of the voting stock of Ventagen, including 47 % by the Company’s founders who are currently significant stockholders of the Company, and trusts for the benefit of their children. The Company is recognizing the $ 1,000 upfront license fee as research and development service revenue, related party, as the Company’s license agreement with Ventagen is within the scope of ASC 606. The license agreement met the contract existence criteria and contained distinct, identifiable performance obligations for which the stand-alone selling prices were readily determinable and allocable. The terms of the agreement contained multiple, distinct performance obligations, including transfer of a license for the Territory, research and development oversight for the trials run by Ventagen, and clinical data sharing. The Company estimated the transaction prices, including any variable consideration, at contract inception and determined the fair value of such obligations. The performance obligation associated with the license transfer was satisfied at a point in time, or at contract inception; however, the Company assigned no value to the license transfer. The remaining $ 1,000 transaction price was allocated between the research and development oversight and clinical data sharing. The Company is recognizing revenue for these obligations over an 8-year period, beginning in 2015, by measuring the progress towards satisfaction of the performance obligations. As clinical oversight and clinical data sharing occurs over the 8 -year clinical trial period, the revenue is recognized over the same period in which the cost for these services is incurred. The Company defers recognition of the portion of the $ 1,000 non-refundable upfront license fee for the portion of the performance obligations that are not satisfied. The Company recognized revenue of $ 31 and $ 63 in each of the three and six months ended June 30, 2022, respectively. The Company recognized revenue of $ 31 and $ 63 in each of the three and six months ended June 30, 2021 , respectively. The license agreement includes a $ 2,500 potential future milestone payment due to the Company upon successful completion of certain separate, distinct events. At this time, the Company cannot estimate when the milestone-related performance obligations are expected to be achieved and will recognize revenue once satisfaction is probable. There was no additional variable consideration, significant financing components, non-cash consideration, or consideration payable to the customer in this agreement. |

Technology License Agreement [Abstract] | |
Technology License Agreement | 14. Technology license agreement On January 20, 2018 the Company entered into an exclusive option agreement ("Option Agreement") with MGB. Pursuant to the Option Agreement, the Company has obtained the exclusive right from MGB to negotiate an exclusive license to make, develop and commercialize rQNestin, a genetically modified oncolytic herpes simplex virus for the treatment of certain types of cancers. Pursuant to the Option Agreement, the Company will support a clinical trial to be conducted at MGB pursuant to the terms of a clinical trial agreement to be negotiated and the Company has committed to remitting $ 750 in support of such clinical trial over the course of approximately three years . Upon execution of the Option Agreement, the Company remitted a non-refundable fee of $ 40 to MGB to be applied toward the Company’s on-going obligations to reimburse patent expenses. In six months ended June 30, 2022 and 2021 , respectively, the Company expensed $ 0 and $ 28 , respectively, for startup and patient fees for clinical trials performed by MGB. On September 15, 2020, the Company exercised the Option Agreement with MGB and entered into an exclusive worldwide patent license agreement with MGB (“the MGB License”). In connection with the MGB License, the Company paid a fee of $ 100 and agreed to reimburse patent costs incurred by MGB, including $ 141 paid at the time of entering into the MGB License. Prior to the first commercial sale, the Company is required to pay MGB an annual license fee of $ 50 beginning following the fourth anniversary of the effective date. The MGB License contains cumulative milestone payments equaling a maximum amount of $ 39,000 upon the achievement of various clinical, commercial and sales milestones of both primary and secondary products. Following the first commercial sale, the Company is required to pay royalties to MGB, which are paid at an increasing rate as net sales increase, ranging from low single digits to high single digits. In addition, after the first commercial sale, the Company is required to pay MGB a pre-determined fixed annual minimum royalty, which amount may be credited against earned royalties starting in the fourth year following the first commercial sale. The Company also agreed to pay a single digit royalty rate on net sales of any derived products. |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | 15. Commitments and contingencies Guarantees The Company has identified the guarantees described below as disclosable, in accordance with ASC 460, Guarantees . As permitted under Delaware law, the Company indemnifies its officers and directors for certain events or occurrences while the officer or director is, or was, serving at the Company’s request in such capacity. The maximum potential amount of future payments the Company could be required to make is unlimited; however, the Company has directors’ and officers’ insurance coverage that should limit its exposure and enable it to recover a portion of any future amounts paid. The Company is a party to a number of agreements entered into in the ordinary course of business that contain typical provisions that obligate the Company to indemnify the other parties to such agreements upon the occurrence of certain events. Such indemnification obligations are usually in effect from the date of execution of the applicable agreement for a period equal to the applicable statute of limitations. The aggregate maximum potential future liability of the Company under such indemnification provisions is uncertain. The Company leases office space under a noncancelable operating lease expiring in 2026 . The Company has standard indemnification arrangements under this lease that require it to indemnify the landlord against all costs, expenses, fines, suits, claims, demands, liabilities, and actions directly resulting from any breach, violation, or nonperformance of any covenant or condition of the lease. As of June 30, 2022 , the Company had no t experienced any losses related to these indemnification obligations, and no material claims with respect thereto were outstanding. The Company does not expect significant claims related to these indemnification obligations and, consequently, concluded that the fair value of these obligations is negligible, and no related reserves have been established. Legal proceedings The Company is not a party to any litigation and does not have contingency reserves established for any litigation liabilities. |

Net loss per share | 16. Net loss per share Net loss per share Basic and diluted net loss per share attributable to common stockholders was calculated a s follows: THREE MONTHS ENDED SIX MONTHS ENDED Numerator: 2022 2021 2022 2021 Net loss attributable to common stockholders $ ( 4,149 ) $ ( 17,080 ) $ ( 5,023 ) $ ( 21,558 ) Denominator: Weighted-average shares of common stock 28,810,224 11,720,530 28,750,431 11,684,374 Net loss per share attributed to common $ ( 0.14 ) $ ( 1.46 ) $ ( 0.17 ) $ ( 1.85 ) The Company’s potentially dilutive securities have been excluded from the computation of dilutive net loss per share as the effect would be to reduce the net loss per share. Therefore, the weighted-average number of shares of common stock outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same. The Company excluded the following potential shares of common stock from the computation of diluted net loss per share attributable to common stockholders because including them would have had an anti-dilutive effect.

Summary of Significant Accounting Policies (Policies) | 6 Months Ended |
Jun. 30, 2022 | |
Accounting Policies [Abstract] | |
Basis of presentation | Basis of presentation The accompanying condensed consolidated financial statements have been prepared in accordance with accounting standards set by the Financial Accounting Standards Board ("FASB"). The FASB sets generally accepted accounting principles ("GAAP") that the Company follows to ensure its financial condition, results of operations, and cash flows are consistently reported. References to GAAP issued by the FASB in these notes to the financial statements are to the FASB Accounting Standards Codification ("ASC") . |
Principles of consolidation | Principles of consolidation The condensed consolidated financial statements include the accounts of Candel Therapeutics, Inc. and its wholly owned subsidiary Candel Therapeutics Securities Corporation. All intercompany transactions and balances have been eliminated. |
Segment Information | Segment Information Operating segments are defined as components of an enterprise about which separate discrete information is available for evaluation by the chief operating decision-maker in deciding how to allocate resources and assess performance. The Company and the Company's chief operating decision maker, the Company's chief executive officer, views the Company's operations and manages its business as a single operating segment. The Company only operates in the United States. |
Emerging growth company | Emerging growth company The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the “Jobs Act”). Under the Jobs Act emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the Jobs Act until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that is (i) no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the Jobs Act. As a result, these consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. |
Unaudited Interim Financial Information | Unaudited Interim Financial Information The accompanying condensed consolidated balance sheet as of June 30, 2022, the condensed consolidated statements of operations for the three and six months ended June 30, 2022 and 2021, the condensed consolidated statements of stockholders’ equity (deficit) for the three and six months ended June 30, 2022 and 2021, the condensed consolidated statements of cash flows for the six months ended June 30, 2022 and 2021, and the related interim disclosures are unaudited. These unaudited condensed consolidated financial statements include all adjustments necessary, consisting of only normal recurring adjustments, to fairly state the financial position and the results of the Company’s operations and cash flows for interim periods in accordance with U.S. GAAP. Interim period results are not necessarily indicative of results of operations or cash flows for a full year or any subsequent interim period. The accompanying condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto for the year ended December 31, 2021 included in the Company’s Annual Report on Form 10-K ("Form 10-K") on file with the SEC. |
Use of estimates | Use of estimates The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and related disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting period. On an ongoing basis, the Company’s management evaluates its estimates, which include but are not limited to management’s judgments of accrued expenses, valuation of stock-based option awards, valuations of warrants, and income taxes. Actual results could differ from those estimates. Prior to the IPO, the Company utilized significant estimates and assumptions in determining the fair value of its common stock. The Company has utilized various valuation methodologies in accordance with the framework of the American Institute of Certified Public Accountants Technical Practice Aid, Valuation of Privately-Held Company Equity Securities Issued as Compensation (the "Practice Aid"), to estimate the fair value of its common stock and warrants. Each valuation methodology includes estimates and assumptions that require the Company’s judgment. These estimates and assumptions include a number of objective and subjective factors, including external market conditions, the prices at which the Company sold shares of preferred stock, the superior rights and preferences of securities senior to the Company’s common stock at the time of, and the likelihood of, achieving a liquidity event, such as an initial public offering or sale. Significant changes to the key assumptions used in the valuations could result in different fair values of common stock at each valuation date. |
Cash and cash equivalents | Cash and cash equivalents The Company considers all highly liquid investments purchased with original final maturities of 90 days or less from the date of purchase to be cash equivalents. Cash and cash equivalents comprise marketable securities with maturities of less than 90 days when purchased. Cash equivalents are reported at fair value. |
Restricted cash | Restricted cash The Company has $ 266 and $ 424 of restricted cash as of June 30, 2022 and December 31, 2021 , respectively, which represents cash held in a restricted bank account under the terms of the Company’s Needham, Massachusetts facility lease and at December 31, 2021, as security for the Company credit card. |
Fair value measurements | Fair value measurements Certain assets and liabilities of the Company are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable: ▪ Level 1—Quoted prices in active markets for identical assets or liabilities. ▪ Level 2—Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data. ▪ Level 3—Unobservable inputs that are supported by little or no market activity that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques. The carrying values of cash and cash equivalents, accounts payable, and accrued expenses approximate their fair values due to the short-term nature of these assets and liabilities. The Company’s warrant liability is carried at fair value and is classified as Level 3 measurement. |
Property and equipment | Property and equipment Property and equipment consist of lab and manufacturing equipment, networking and computer equipment, furniture and fixtures and leasehold improvements. Property and equipment are recorded at cost, and depreciated using the straight-line method over the estimated useful lives of the respective assets: ASSET ESTIMATED USEFUL LIFE Networking and computer equipment 5 years Laboratory equipment 5 years Manufacturing equipment 5 years Furniture and fixtures 5 years Leasehold improvements Shorter of the useful life or remaining lease term |
Leases | Leases The Company adopted ASC 842 as of January 1, 2022 and elected the transition method under ASU 2016-02 whereby the Company records a right-of-use asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. The Company also elected to apply the practical expedients intended to ease transition. Accordingly, the Company has only applied ASC 842 to leases existing as of January 1, 2022. The Company determines if an arrangement is, or contains, a lease at inception. Lease right of use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Lease right of use assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments to be made over the lease term. The lease right of use asset is equal to the lease liability and adjusted for prepaid rent, initial direct costs, and incentives. As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. The lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating lease expense is recognized on a straight-line basis over the lease term. The Company has elected to not apply the recognition requirements of ASC 842 for short-term leases, which is defined as a lease that, at the lease commencement date, has a lease term of 12 months or less and does not include an option to purchase the underlying asset that the Company is reasonably certain to exercise. For real estate lease agreements entered into or modified after the adoption of ASC 842 that include lease and non-lease components, the Company has elected to account for the lease and non-lease components, such as common area maintenance charges, as a single lease component term. |
Concentrations of credit risk | Concentrations of credit risk Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents and marketable securities. Periodically, the Company maintains deposits and investments in accredited financial institutions in-excess of the federally insured limits. The Company deposits its cash in financial institutions with a high credit quality and has not experienced any losses on such accounts and does not believe it is exposed to any unusual credit risk beyond the normal risk associated with commercial banking relationships. |
Impairment of long lived assets | Impairment of long-lived assets Long-lived assets to be held and used are tested for recoverability whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. Factors that the Company considers in deciding when to perform an impairment review include significant underperformance of the business in relation to expectations, significant negative industry or economic trends and significant changes or planned changes in the use of the assets. If an impairment review is performed to evaluate a long-lived asset group for recoverability, the Company compares forecasts of undiscounted cash flows expected to result from the use and eventual disposition of the long-lived asset group to its carrying value. An impairment loss would be recognized when estimated undiscounted future cash flows expected to result from the use of an asset group are less than its carrying amount. The impairment loss would be based on the excess of the carrying value of the impaired asset group over its fair value, determined based on discounted cash flows. Long-lived assets consist of fixed assets and operating lease assets. In the fourth quarter of 2021, the Company recorded an impairment charge of approximately $ 553 related to manufacturing equipment that the Company does not plan to use for its intended use and recorded a reserve to reduce the carrying value to its estimated realizable value. The Company has not recorded any additional impairment losses on such long-lived assets . |
Revenue recognition | Revenue recognition The Company applies Accounting Standards Codification, or ASC, Topic 606, Revenue from Contracts with Customers, (ASC 606). This standard applies to all contracts with customers, except for contracts that are within the scope of other standards, such as leases, insurance, collaboration arrangements and financial instruments. Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations, and then assesses whether or not each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied . |
Research and development costs and accruals | Research and development costs and accruals Research and development expenses include salaries and benefits, materials and supplies, preclinical and clinical trial expenses, stock-based compensation expense, depreciation of equipment, contract services and other outside expenses. The Company has entered into various research and development-related contracts with clinical and research institutions, contract research organizations, and other companies. These agreements are generally cancelable, and related payments are recorded as research and development expenses as incurred. Costs of certain development activities, such as manufacturing, pre-clinical and clinical trial expenses, are recognized based on an evaluation of the progress to completion of specific tasks. Payments for these activities are based on the terms of the individual arrangements, which may differ from the pattern of costs incurred, and are reflected in the financial statements as prepaid or accrued research and development costs. Nonrefundable advance payments for goods or services to be received in the future for use in research and development activities are deferred and capitalized. The capitalized amounts are expensed as the related goods are delivered or the services are performed. Costs incurred in obtaining technology licenses and intellectual property are charged to research and development expenses as acquired in-process research and development if the technology licensed or intellectual property acquired has not reached technological feasibility and has no alternative future use. |
Patent costs | Patent costs All patent-related costs incurred in connection with preparing, filing, maintaining and prosecuting patent applications are expensed as incurred due to the uncertainty about the recovery of the expenditure. Amounts incurred are classified in general and administrative expenses. |
Stock-based compensation | Stock-based compensation The Company accounts for its stock-based compensation in accordance with ASC Topic 718, Compensation—Stock Compensation (ASC 718). ASC 718 requires all share-based payments to employees and directors to be recognized as expense in the consolidated statements of operations based on their grant date fair values. In addition, in accordance with FASB Accounting Standards Update ("ASU") 2016-09 which identifies areas for simplification of several areas of share-based payment transactions, the Company treats non-employee grants the same as employee grants. The Company estimates the fair value of options granted using the Black-Scholes option pricing model for stock option grants to both employees and non-employees. The Company believes the fair value of the stock options granted to non-employees is more reliably determinable than the fair value of the services provided. The Black-Scholes option pricing model requires inputs based on certain subjective assumptions, including (a) the expected stock price volatility, (b) the expected term of the award, (c) the risk-free interest rate and (d) expected dividends. Due to a lack of company-specific historical and implied volatility data, the Company has based its computation of expected volatility on the historical volatility of a representative group of public companies with similar characteristics to the Company, including stage of product development and life science industry focus. The historical volatility is calculated based on a period of time commensurate with the expected term assumption. The Company uses the simplified method as prescribed by the SEC Staff Accounting Bulletin No. 107, Share-Based Payment, to calculate the expected term for options granted to employees as it does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term. The expected term is applied to the stock option grant group as a whole, as the Company does not expect substantially different exercise or post-vesting termination behavior among its employee population. For options granted to non-employees, the Company utilizes the contractual term of the share-based payment as the basis for the expected term assumption. The risk-free interest rate is based on a treasury instrument whose term is consistent with the expected term of the stock options. The expected dividend yield is assumed to be zero as the Company has never paid dividends and has no current plans to pay any dividends on its common stock. Prior to the IPO, there were significant judgments and estimates inherent in the determination of the fair value of the Company’s common stock. These estimates and assumptions included a number of objective and subjective factors, including external market conditions, the prices at which the Company sold shares of preferred stock, the superior rights and preferences of securities senior to its common stock at the time of, and the likelihood of, achieving a liquidity event, such as an initial public offering or sale. The Company generally expenses the fair value of its share-based compensation awards to employees and non-employees on a straight-line basis over the requisite service period, which is generally the vesting period. |
Government grants | Government grants The Company has applied for grants for the reimbursement of expenditures with the National Institutes of Health ("NIH") for certain qualified operating expenditures. The Company recognizes government grants when there is reasonable assurance that the Company will comply with the conditions attached to the grant arrangement and the grant will be received. Government grants for research and development efforts are reco rded as grant income and classified in other income in the statements of operations. The Company had no government grant revenue in 2022 and recognized government grant revenue of $ 605 and $ 796 for t he three and six months ended June 30, 2021. Grant income is recognized as a component of other income/(expense), net in the condensed consolidated statements of operations . The Company's grant with the NIH was completed at the end of 2021. |
Income taxes | Income taxes The Company accounts for income taxes using the asset and liability method in accordance with ASC Topic 740, Income Taxes (ASC 740) which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the financial statements or in the Company’s tax returns. Deferred tax assets and liabilities are determined on the basis of the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Changes in deferred tax assets and liabilities are recorded in the provision for income taxes. The Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent it believes, based upon the weight of available evidence, that it is more likely than not that all or a portion of the deferred tax assets will not be realized, a valuation allowance is established through a charge to income tax expense. Potential for recovery of deferred tax assets is evaluated by estimating the future taxable profits expected and considering prudent and feasible tax planning strategies. At June 30, 2022 and December 31, 2021, the Company has concluded that a full valuation allowance is necessary for its deferred tax assets (see Note 12). The Company accounts for uncertainty in income taxes by applying the two-step process to determine the amount of tax benefit to be recognized in the financial statements. First, the tax position must be evaluated to determine the likelihood that it will be sustained upon external examination by the taxing authorities. If the tax position is deemed more-likely-than-not to be sustained, the tax is then assessed as the amount of benefits to be recognized in the consolidated financial statements. The amount of benefits that may be used are the largest amounts that have a greater than 50 % likelihood of being realized upon ultimate settlement. The provision for income taxes includes the effects of any resulting tax reserves or unrecognized tax benefits that are considered appropriate, as well as the related net interest and received. |
Net loss per share | Net loss per share Basic net loss per share is computed by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed using the weighted-average number of shares of common stock outstanding during the period and, if dilutive, the weighted-average number of potential shares of common stock. Diluted net loss per share is the same as basic net loss per share for the three and six months ended June 30, 2022 and 2021 since all potential shares of common stock instruments are anti-dilutive as a result of the loss for such periods. The Company’s convertible preferred stock contractually entitles the holders of such shares to participate in dividends but does not contractually require the holders of such shares to participate in losses of the Company. Accordingly, in periods in which the Company reports a net loss, such losses are not allocated to such participating securities. In periods where the Company reports a net loss attributable to common stockholders, diluted net loss per share is the same as basic net loss per share, since dilutive shares of common stock are not assumed to have been issued if their effect is anti-dilutive. The Company reported a net loss attributable to common stockholders for the three and six months ended June 30, 2022 and 2021 . |
Recently adopted accounting standards | Recently adopted accounting standards In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”) , as amended by various subsequently issued ASUs. The standard requires lessees to recognize an operating lease with a term greater than one year on their balance sheets as a right-of-use asset and corresponding lease liability, measured at the present value of the lease payments. Lessees are required to classify leases as either finance or operating leases. If the lease is effectively a financed purchase by the lessee, it is classified as a financing lease, otherwise it is classified as an operating lease. This classification will determine the pattern of recognition of lease cost on our condensed and consolidated statement of operations over the term of the lease. In July 2018, the FASB also issued ASU 2018-11, Leases (Topic 842): Targeted Improvements (“ASU 2018-11”) , which permits entities to continue applying legacy guidance in ASC 840, Leases, including its disclosure requirements, in the comparative periods presented in the year that the entity adopts the new leasing standard. The Company elected the package of practical expedients permitted under the transition guidance within the standard. Accordingly, the Company did not reassess the conclusion of whether the existing arrangements contain a lease, lease classification and initial direct costs under ASC 842. In June 2020, the FASB also issued ASU 2020-05, Revenue from contracts with customers (Topic 606) and Leases (Topic 842): effective dates for certain entities, which deferred the effective date certain entities were required to adopt ASC 842. The update extended the effective date for adoption of ASC 842 until fiscal years beginning after December 15, 2021. As an emerging growth company we were not required to adopt ASC 842 until January 1, 2022. The Company adopted the standard on January 1, 2022 using the effective date method. As such, the condensed consolidated balance sheets and statements of operations for prior periods will not be comparable in the year of adoption of ASC 842. As a result of the adoption of ASC 842, the Company recorded a lease right of use asset of $ 1,264 and a lease liability of $ 2,368 on the condensed consolidated balance sheets as of January 1, 2022 related to an operating lease. The Company derecognized deferred rent liabilities, which makes up the difference between the lease right of use asset and lease liability. The adoption of the standard did not have a material impact on the Company’s condensed consolidated statement of operations or condensed consolidated statement of cash flows. In August 2020, the FASB issued ASU 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40 ). The guidance simplifies the complexity associated with applying U.S. GAAP for certain financial instruments with characteristics of liabilities and equity. This ASU (1) simplifies the accounting for convertible debt instruments and convertible preferred stock by removing guidance in ASC 470-20, Debt: Debt with Conversion and Other Options , that requires entities to account for beneficial conversion features and cash conversion features in equity, separately from the host convertible debt or preferred stock; (2) revises the scope exception from derivative accounting in ASC 815-40 for freestanding financial instruments and embedded features that are both indexed to the issuers own stock and classified in stockholders' equity, by removing certain criteria required for equity classification; and (3) revises the guidance in ASC 260, Earnings Per Share , to require entities to calculate diluted earnings per share for convertible instruments by using the if-converted method. As an emerging growth company, we are not required to adopt ASU 2020-06 until January 1, 2024, however early adoption is permitted. The Company elected to early adopt the standard on January 1, 2022 and upon adoption, there was no impact to our condensed consolidated statement of operations and cash flows and our basic and diluted net loss per share amounts. In November 2021, the FASB issued ASU 2021-10, which created Topic 832, Government Assistance, which requires business entities to disclose information about certain government assistance they receive. The ASU requires qualitative and quantitative disclosures around the nature of transactions and related accounting policy used, the line items on the balance sheet and income statement that are affected, and the significant terms and conditions of the transactions. The ASU is effective for fiscal years beginning after December 15, 2021 . The Company believes its historical disclosure already met the requirements of the new standard. As such, no changes or additional disclosure was determined to be necessary . |
