Organization and Summary of Significant Accounting Policies | 1. Organization and Summary of Significant Accounting Policies Organization HCW Biologics Inc. (the “Company”) is a clinical stage biopharmaceutical company focused on discovering and developing novel immunotherapies to lengthen healthspan by disrupting the link between chronic, low-grade inflammation and age-related diseases. The Company believes age-related low-grade chronic inflammation, or “inflammaging,” is a significant contributing factor to several chronic diseases and conditions, such as cancer, cardiovascular disease, diabetes, neurodegenerative diseases, and autoimmune diseases. The Company is located in Miramar, Florida and was incorporated in the state of Delaware in April 2018. Liquidity As of September 30, 2023, the Company had not generated any revenue from commercial product sales of its internally-developed immunotherapeutic products for the treatment of cancer and other age-related diseases. In the course of its development activities, the Company has sustained operating losses and expects to continue to incur operating losses for the foreseeable future. Since inception, substantially all the Company’s activities have consisted of research, development, establishing large-scale cGMP production for clinical trials, and raising capital. The Company's total revenues to date have been generated solely from the Wugen License and its manufacturing and supply arrangement with Wugen. In the three and nine months ended September 30, 2023, the Company recognized revenues from manufacturing and supply of materials for Wugen of $ 853,102 and $ 1.5 million, respectivel y. As of September 30, 2023, the Company had cash and cash equivalents of $ 11.2 million and a deposit for interest reserve of $ 5.3 million. Since inception to September 30, 2023 , the Company incurred cumulative net losses of $ 57.1 million. Management expects to incur additional losses in the future to conduct product research and development and recognizes th e need to raise additional capital to fully implement its business plan. In November 2023, the Company expects to begin to draw down on its $ 26.3 million Development Line of Credit Agreement, the proceeds of which will be primarily used for the buildout of the Company's headquarters, including upgraded research laboratories and a new manufacturing facility. See Note 8. Commitments and Contingencies - Project Financing herein. The Company intends to raise capital through additional debt or equity financings. In addition, the Company intends to continue its efforts to enter into business development transactions. Business development efforts are focused on out-licensing rights to non-core assets or regional markets, third-party collaboration funding, cooperative agreements for clinical trials, and other transactions. However, if the Company is not able to obtain financing at adequate levels, it will need to reevaluate its operating plan and may be required to delay the development of some of its products. Summary of Significant Accounting Policies Basis of Presentation Unaudited Interim Financial Information The accompanying unaudited condensed interim financial statements as of September 30, 2023 and for the three and nine months ended September 30, 2022 and 2023 have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to Article 10 of Regulation S-X of the Securities Act of 1933, as amended (the “Securities Act”). Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. These unaudited condensed interim financial statements include only normal and recurring adjustments that the Company believes are necessary to fairly state the Company’s financial position and the results of its operations and cash flows. The results for the three and nine months ended September 30, 2023 are not necessarily indicative of the results expected for the full fiscal year or any subsequent interim period. The condensed balance sheet at December 31, 2022 has been derived from the audited financial statements at that date but does not include all disclosures required by U.S. GAAP for complete financial statements. Because all of the disclosures required by U.S. GAAP for complete financial statements are not included herein, these unaudited condensed interim financial statements and the notes accompanying them should be read in conjunction with the Company’s audited financial statements for the year ended December 31, 2022 which appear in the Company’s Annual Report on Form 10-K (No. 001-40591) filed for the year ended December 31, 2022 with the Securities and Exchange Commission (the “SEC”) on March 28, 2023 and in other filings with the SEC. Deposit for Interest Reserve The Company has established an interest reserve account for the purpose of paying interest on outstanding debt under the Development Line of Credit Agreement which is further described in Note 8. Commitments and Contingencies - Project Financing herein. As of September 30, 2023 , there was a balance of $ 5.3 million included in Deposit for interest reserve in noncurrent assets on the accompanying condensed balance sheet. Revenue Recognition The Company accounts for revenues in accordance with Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (“Topic 606”). To determine revenue recognition for arrangements that fall within the scope of Topic 606, the Company 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 Company satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that it will collect the consideration it is entitled to in exchange for the goods or services transferred to the customer. At contract inception, the Company assesses the goods or services promised within each contract, determines those that are performance obligations, and assesses whether 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. To date, the Company's revenues have been generated solely from transactions with Wugen. The Wugen License includes licenses of intellectual property, cost reimbursements, upfront signing fees, milestone payments and royalties on future licensee’s product sales. In addition, the Company and Wugen have an agreement for supply of materials, from which the Company also recognizes revenues. License Grants: For out-licensing arrangements that include a grant of a license to the Company’s intellectual property, the Company considers whether the license grant is distinct from the other performance obligations included in the arrangement. For licenses that are distinct, the Company recognizes revenues from nonrefundable, upfront payments and other consideration allocated to the license when the license term has begun and the Company has provided all necessary information regarding the underlying intellectual property to the customer, which generally occurs at or near the inception of the arrangement. Milestone and Contingent Payments: At the inception of the arrangement and at each reporting date thereafter, the Company assesses whether it should include any milestone and contingent payments or other forms of variable consideration in the transaction price using the most likely amount method. If it is probable that a significant reversal of cumulative revenue would not occur upon resolution of the uncertainty, the associated milestone value is included in the transaction price. At the end of each subsequent reporting period, the Company re-evaluates the probability of achievement of each such milestone and any related constraint and, if necessary, adjusts its estimate of the overall transaction price. Since milestone and contingent payments may become payable to the Company upon the initiation of a clinical study or filing for or receipt of regulatory approval, the Company reviews the relevant facts and circumstances to determine when the Company should update the transaction price, which may occur before the triggering event. When the Company updates the transaction price for milestone and contingent payments, the Company allocates the changes in the total transaction price to each performance obligation in the agreement on the same basis as the initial allocation. Any such adjustments are recorded on a cumulative catch-up basis in the period of adjustment, which may result in recognizing revenue for previously satisfied performance obligations in such period. The Company’s licensees will generally pay milestones payments subsequent to achievement of the triggering event. Materials Supply: The Company provides clinical and research grade materials so that licensees may develop products based on the licensed molecules. The Company plans to enter into commercialization supply agreements when licensees enter the commercial stage of their company. The amounts billed are recognized as revenue as the performance obligations are satisfied by the Company, once the Company determines that a contract exists. On June 18, 2021, the Company entered into a master services agreement (“MSA”) for the supply of materials for clinical development of licensed products. Under the MSA, the Company enters into statements-of-work (“SOWs”) for transactions for the purchase of clinical and research grade materials which meet all requirements necessary to qualify as a contract under Topic 606. The sale of clinical and research material supplied by the Company each represents a single performance obligation that is satisfied over time. The Company recognizes revenue using an input method based on the costs incurred relative to the total expected cost, which determines the extent of the Company's progress toward completion. As part of the accounting for these arrangements, the Company must develop estimates and assumptions that require judgement to determine the progress towards completion. The Company reviews its estimate of the progress toward completion based on the best information available to recognize the cumulative progress toward completion as of the end of each reporting period, and makes revisions to such estimates, if facts and circumstances change during each reporting period. The Company recognized revenue related to sale of development supply materials to its licensee, Wugen, of $ 1.8 million and $ 5.4 million, respectively, for the three and nine months ended September 30, 2022 ; and $ 853,102 and $ 1.5 million, resp ectively, for three and nine months ended September 30, 2023 . Investments The Company holds a minority interest in Wugen which is accounted for using the measurement alternative whereby the investment is recorded at cost less impairment, adjusted for observable price changes in orderly transactions for an identical or similar investment of the same investee. No impairment has been recognized on the minority interest in Wugen as of September 30, 2023. As of December 31, 2022 and September 30, 2023 , the Company included $ 1.6 million for the investment in Wugen in Investments in the accompanying condensed balance sheets. From time to time, the Company invests in bills and notes issued by the U.S. Treasury which are classified as trading securities. The Company reported a fair value of $ 9.7 million and nil for the fair value of investments in U.S. Treasury bills as of December 31, 2022 and September 30, 2023, respectively, included in Short-term investments in the accompanying condensed balance sheets. Operating Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in Other assets, Accrued liabilities and other current liabilities, and Other liabilities on the accompanying condensed balance sheets. Operating lease Right of Use (“ROU”) assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. The Company has a lease agreement with lease and non-lease components, which are accounted for separately. Net Loss Per Share Basic loss per share of common stock is computed by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during each period. Diluted loss per share of common stock includes the effect, if any, from the potential exercise of stock options and unvested shares of restricted stock, which would result in the issuance of incremental shares of common stock. For diluted net loss per share, the weighted-average number of shares of common stock is the same for basic net loss per share due to the fact that when a net loss exists, dilutive securities are not included in the calculation as the impact is anti-dilutive. |

Income Taxes | 7. Income Taxes The Company computes its quarterly income tax expense/(benefit) by using a forecasted annual effective tax rate and adjusts for any discrete items arising during the quarter. The Company did no t have a provision for income taxes (current or deferred tax expense) as of December 31, 2022 and September 30, 2023 . The Company will continue to maintain a 100 % valuation allowance on total deferred tax assets. The Company believes it is more likely than not that the related deferred tax asset will not be realized. As a result, the Company’s effective tax rate will remain at 0.00 % because no items either estimated or discrete items would impact the tax provision. |

Commitments and Contingencies | . Commitments and Contingencies Operating Leases The Company has operating leases for approximately 12,250 square feet of space located in Miramar, Florida. The leases have a two-year term which commenced on March 1, 2022 and will terminate on February 29, 2024 . Upon the commencement of the leases, the Company used its incremental borrowing rate of 6.0 % to determine the amounts to recognize for a ROU asset and a lease liability. There are no obligations under finance leases. The components of the lease expense for the three and nine months ended September 30, 2023 were as follows: For the Three Months For the Nine Months Ended September 30, 2023 Operating lease cost $ 42,413 $ 127,238 Supplemental cash flow information related to lease for the nine months ended September 30, 2023 was as follows: For the Nine Months Ended September 30, 2023 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows $ 127,229 Right-of-use assets obtained in exchange for lease obligations: Operating lease $ 120,973 As of September 30, 2023, the supplemental balance sheet information related to leases was as follows: As of September 30, 2023 Operating lease right-of-use assets $ 69,624 Operating lease liabilities, current $ 70,669 As of September 30, 2023, the remaining lease payments were as follows: 2023 $ 42,831 2024 28,693 Total future minimum lease payments $ 71,524 For the three months ended September 30, 2022 and 2023, rent expense recognized by the Company was $ 43,700 and $ 42,400 , respectively, of which $ 22,200 and $ 22,200 , respectively, is included in research and development in the accompanying condensed statements of operations. For the nine months ended September 30, 2022 and 2023, rent expense recognized by the Company was $ 130,300 and $ 127,200 , respectively, of which $ 57,800 and $ 66,600 , respectively, is included in research and development in the accompanying condensed statements of operations. Contractual Commitments The Company entered into an agreement with a third-party global contract development and manufacturer of biologics for the manufacture of the Company’s proprietary molecules for use in clinical trials. At December 31, 2022 and September 30, 2023 , future payment obligations under such agreements were $ 406,000 and $ 1.8 million, respectively. In addition, as of December 31, 2022, the Company committed to purchase upstream processing and fluid management equipment for $ 1.6 million, and it advanced $ 495,000 for this purchase as of September 30, 2023. Project Financing On April 21, 2023, the Company entered into a secured Development Line of Credit Agreement (such agreement as amended from time to time, the "2023 Loan Agreement") with Prime Capital Ventures, LLC ("Prime"), pursuant to which Prime will advance loans to the Company in a principal amount not to exceed $ 26.3 million with a scheduled maturity of April 20, 2028 (the "Prime Maturity Date"). The Company has the option to prepay the balance of the loan prior to the Prime Maturity date without penalty. The note issued pursuant to the 2023 Loan Agreement bears interest at a fixed rate equal to 7.00 % per annum, due monthly in arrears on the first day of each month. The primary purpose of the loan is to provide the funding required to complete the buildout of the Company's new headquarters, including improved research laboratories and a vivarium to support the Company's preclinical research efforts, and a manufacturing facility to produce GMP material to support the Company's clinical development as well as produce material to support the clinical development of its licensee, Wugen. Under the 2023 Loan Agreement, the Company was required to fund an interest reserve bank account controlled by Prime in the amount of $ 5.3 million to fund the interest payments due thereunder. The balance of the reserve account is presented in Deposit for interest reserve in noncurrent assets on the accompanying condensed balance sheet. As of September 30, 2023 , the Company had no outstanding borrowings under the 2023 Loan Agreement. On August 10, 2023, the Company obtained construction permits required to begin the buildout of its new headquarters. This satisfied the final condition precedent to accessing the $ 26.3 million line of credit. The Company will incur $ 1.8 million in debt issuance costs in connection to the Prime loan, which will be earned and payable upon the first draw down. In November 2023, the Company expects to begin to draw down funds available under the 2023 Loan Agreement. Legal From time to time, the Company is a party to or otherwise involved in legal proceedings, including suits, assessments, regulatory actions and investigations generally arising out of the normal course of business. In addition, the Company enters into agreements that may include indemnification provisions, pursuant to which the Company agrees to indemnify, hold harmless and defend the indemnified parties for losses suffered or incurred by the indemnified party. When the Company believes that the outcome of such a matter will result in a liability that is probable to be incurred and result in a potential loss, or range of loss, that can be reasonably estimated, the Company will accrue a liability and make the appropriate disclosure in the footnotes to the financial statements. On December 23, 2022, Altor BioScience, LLC and NantCell, Inc. (“Altor/NantCell”) initiated an arbitration against Dr. Hing C. Wong, the Company’s Founder and Chief Executive Officer, in California alleging breach of contract and fiduciary duty, among other claims. On that same date, Altor/NantCell filed a lawsuit against the Company in federal court alleging misappropriation of trade secrets, inducement of breach of contract and breach of fiduciary duty, among other claims against the Company. On January 31, 2023, the Company filed a motion to compel arbitration, a motion for the stay of the litigation, and a motion to dismiss the complaint (“motion to compel”). On April 18, 2023, the U.S. District Court for the Southern District of Florida (the “Court”) heard oral argument on the Company’s motion to compel and ordered the parties to provide supplemental briefing by April 28, 2023. Before the Court ruled on the Company’s motion to compel, on April 26, 2023, the parties stipulated that Altor/NantCell’s action against the Company would be consolidated with the Altor/NantCell arbitration demand against Dr. Wong. On April 27, 2023, the Court approved the parties’ stipulation and ordered the parties to arbitration. On May 1, 2023, Altor/NantCell filed a demand against the Company before JAMS. On May 3, 2023, Altor/NantCell dismissed the federal court action without prejudice and the Court ordered the case dismissed without prejudice and closed the case. Altor/NantCell’s proceeding against the Company is now proceeding in arbitration before JAMS. Inflationary Cost Environment, Geopolitical Risks and Other Macroeconomic Factors The operations have been affected by many headwinds, including inflationary pressures, rising interest rates, ongoing global supply chain disruptions resulting from increased geopolitical tensions such as the war in the Middle East, the conflict between Russia and Ukraine, Chinese aggression towards Taiwan, financial market volatility and currency movements. The Company has been impacted by inflation, and may continue to be so, when procuring materials required for the buildout of our new headquarters, the costs for recruiting and retaining employees and other employee-related costs. Management employs a number of strategies to effectively navigate these issues, including product redesign, alternate sourcing, and establishing contingencies in budgeting and timelines. Future developments in these and other areas present material uncertainty and risk with respect to the Company's clinical trials, IND-enabling activities, buildout of the new headquarters, as well as the Company's financial condition and results of operations. The extent and duration of such events and conditions, and resulting disruptions to our operations, are highly unpredictable. |

Basis of Presentation | Basis of Presentation Unaudited Interim Financial Information The accompanying unaudited condensed interim financial statements as of September 30, 2023 and for the three and nine months ended September 30, 2022 and 2023 have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to Article 10 of Regulation S-X of the Securities Act of 1933, as amended (the “Securities Act”). Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. These unaudited condensed interim financial statements include only normal and recurring adjustments that the Company believes are necessary to fairly state the Company’s financial position and the results of its operations and cash flows. The results for the three and nine months ended September 30, 2023 are not necessarily indicative of the results expected for the full fiscal year or any subsequent interim period. The condensed balance sheet at December 31, 2022 has been derived from the audited financial statements at that date but does not include all disclosures required by U.S. GAAP for complete financial statements. Because all of the disclosures required by U.S. GAAP for complete financial statements are not included herein, these unaudited condensed interim financial statements and the notes accompanying them should be read in conjunction with the Company’s audited financial statements for the year ended December 31, 2022 which appear in the Company’s Annual Report on Form 10-K (No. 001-40591) filed for the year ended December 31, 2022 with the Securities and Exchange Commission (the “SEC”) on March 28, 2023 and in other filings with the SEC. |
Deposit for Interest Reserve | Deposit for Interest Reserve The Company has established an interest reserve account for the purpose of paying interest on outstanding debt under the Development Line of Credit Agreement which is further described in Note 8. Commitments and Contingencies - Project Financing herein. As of September 30, 2023 , there was a balance of $ 5.3 million included in Deposit for interest reserve in noncurrent assets on the accompanying condensed balance sheet. |
Revenue Recognition | Revenue Recognition The Company accounts for revenues in accordance with Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (“Topic 606”). To determine revenue recognition for arrangements that fall within the scope of Topic 606, the Company 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 Company satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that it will collect the consideration it is entitled to in exchange for the goods or services transferred to the customer. At contract inception, the Company assesses the goods or services promised within each contract, determines those that are performance obligations, and assesses whether 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. To date, the Company's revenues have been generated solely from transactions with Wugen. The Wugen License includes licenses of intellectual property, cost reimbursements, upfront signing fees, milestone payments and royalties on future licensee’s product sales. In addition, the Company and Wugen have an agreement for supply of materials, from which the Company also recognizes revenues. License Grants: For out-licensing arrangements that include a grant of a license to the Company’s intellectual property, the Company considers whether the license grant is distinct from the other performance obligations included in the arrangement. For licenses that are distinct, the Company recognizes revenues from nonrefundable, upfront payments and other consideration allocated to the license when the license term has begun and the Company has provided all necessary information regarding the underlying intellectual property to the customer, which generally occurs at or near the inception of the arrangement. Milestone and Contingent Payments: At the inception of the arrangement and at each reporting date thereafter, the Company assesses whether it should include any milestone and contingent payments or other forms of variable consideration in the transaction price using the most likely amount method. If it is probable that a significant reversal of cumulative revenue would not occur upon resolution of the uncertainty, the associated milestone value is included in the transaction price. At the end of each subsequent reporting period, the Company re-evaluates the probability of achievement of each such milestone and any related constraint and, if necessary, adjusts its estimate of the overall transaction price. Since milestone and contingent payments may become payable to the Company upon the initiation of a clinical study or filing for or receipt of regulatory approval, the Company reviews the relevant facts and circumstances to determine when the Company should update the transaction price, which may occur before the triggering event. When the Company updates the transaction price for milestone and contingent payments, the Company allocates the changes in the total transaction price to each performance obligation in the agreement on the same basis as the initial allocation. Any such adjustments are recorded on a cumulative catch-up basis in the period of adjustment, which may result in recognizing revenue for previously satisfied performance obligations in such period. The Company’s licensees will generally pay milestones payments subsequent to achievement of the triggering event. Materials Supply: The Company provides clinical and research grade materials so that licensees may develop products based on the licensed molecules. The Company plans to enter into commercialization supply agreements when licensees enter the commercial stage of their company. The amounts billed are recognized as revenue as the performance obligations are satisfied by the Company, once the Company determines that a contract exists. On June 18, 2021, the Company entered into a master services agreement (“MSA”) for the supply of materials for clinical development of licensed products. Under the MSA, the Company enters into statements-of-work (“SOWs”) for transactions for the purchase of clinical and research grade materials which meet all requirements necessary to qualify as a contract under Topic 606. The sale of clinical and research material supplied by the Company each represents a single performance obligation that is satisfied over time. The Company recognizes revenue using an input method based on the costs incurred relative to the total expected cost, which determines the extent of the Company's progress toward completion. As part of the accounting for these arrangements, the Company must develop estimates and assumptions that require judgement to determine the progress towards completion. The Company reviews its estimate of the progress toward completion based on the best information available to recognize the cumulative progress toward completion as of the end of each reporting period, and makes revisions to such estimates, if facts and circumstances change during each reporting period. The Company recognized revenue related to sale of development supply materials to its licensee, Wugen, of $ 1.8 million and $ 5.4 million, respectively, for the three and nine months ended September 30, 2022 ; and $ 853,102 and $ 1.5 million, resp ectively, for three and nine months ended September 30, 2023 . |
Investment | Investments The Company holds a minority interest in Wugen which is accounted for using the measurement alternative whereby the investment is recorded at cost less impairment, adjusted for observable price changes in orderly transactions for an identical or similar investment of the same investee. No impairment has been recognized on the minority interest in Wugen as of September 30, 2023. As of December 31, 2022 and September 30, 2023 , the Company included $ 1.6 million for the investment in Wugen in Investments in the accompanying condensed balance sheets. From time to time, the Company invests in bills and notes issued by the U.S. Treasury which are classified as trading securities. The Company reported a fair value of $ 9.7 million and nil for the fair value of investments in U.S. Treasury bills as of December 31, 2022 and September 30, 2023, respectively, included in Short-term investments in the accompanying condensed balance sheets. |
Operating Leases | Operating Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in Other assets, Accrued liabilities and other current liabilities, and Other liabilities on the accompanying condensed balance sheets. Operating lease Right of Use (“ROU”) assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease ROU asset also includes any lease payments made and excludes lease incentives and initial direct costs incurred. The Company has a lease agreement with lease and non-lease components, which are accounted for separately. |
Net Loss Per Share | Net Loss Per Share Basic loss per share of common stock is computed by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during each period. Diluted loss per share of common stock includes the effect, if any, from the potential exercise of stock options and unvested shares of restricted stock, which would result in the issuance of incremental shares of common stock. For diluted net loss per share, the weighted-average number of shares of common stock is the same for basic net loss per share due to the fact that when a net loss exists, dilutive securities are not included in the calculation as the impact is anti-dilutive. |
