1. Organization
Overview
Harvard Apparatus Regenerative Technology, Inc. (“Harvard Apparatus Regenerative Technology” or the “Company”) is a biotechnology company focused on the development of regenerative medicine treatments for disorders of the gastro-intestinal system and other organs that result from cancer, trauma or birth defects. The Company believes its technology is likely to be used to repair wounds or other damage or defects resulting from esophageal cancer, esophageal injuries, and birth defects in the esophagus. The Company believes additional product candidates in its development pipeline may repair wounds or other damage or defects resulting from intestinal cancer and uterus wounds. Since inception, the Company has devoted substantially all of its efforts to business planning, research and development, recruiting management and technical staff, and acquiring operating assets.
Consumer Health Products
In the second quarter of 2023, the Company’s subsidiary in Hong Kong, Harvard Apparatus Regenerative Technology Limited, or Consumer Health Products, started focusing on sales of consumer health products.
Consumer Health Products includes a broad range of products focused on personal healthcare including dietary supplements. The Company currently sells dietary supplements through Consumer Health Products. These products are commercially marketed to the general public and initially targeted at consumers in Asia through eCommerce (online sales).
Going Concern
The Company has incurred substantial operating losses since its inception, and as of September 30, 2025, had an accumulated deficit of approximately $104.9 million and will require additional financing to fund future operations. The Company expects that its operating cash on-hand as of September 30, 2025 of approximately $1.3 million will enable it to fund its operating expenses and capital expenditure requirements into the fourth quarter of 2025. Therefore, these conditions raise substantial doubt about the Company’s ability to continue as a going concern.
The Company will need to raise additional capital to fund its current operations. In the event the Company is unable to raise additional capital from outside sources during the fourth quarter of 2025, it may be forced to curtail or cease its operations.
Cash requirements and cash resource needs will vary significantly depending upon the timing of the financial and other resource needs that will be required to complete ongoing development, pre-clinical and clinical testing of product candidates, as well as regulatory efforts and collaborative arrangements necessary for the Company’s product candidates that are currently under development. The Company is currently seeking and will continue to seek financing from other existing and/or new investors to raise necessary funds through a combination of public or private equity offerings. The Company may also pursue debt financings, other financing mechanisms, research grants, or strategic collaborations and licensing arrangements. The Company may not be able to obtain additional financing on favorable terms, if at all.
The Company’s operations will be adversely affected if it is unable to raise or obtain needed funding and may materially affect the Company’s ability to continue as a going concern. The accompanying condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern and therefore, the condensed consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amount and classifications of liabilities that may result from the outcome of this uncertainty.

2. Summary of Significant Accounting Policies and Recently Issued Accounting Pronouncements
Summary of Significant Accounting Policies
The accounting policies underlying the accompanying condensed consolidated financial statements are those set forth in Note 2 to the condensed consolidated financial statements for the year ended December 31, 2024 included in the Company’s Annual Report on Form 10-K filed with the SEC on March 31, 2025 (the “Form 10-K”).
Principles of Consolidation
The condensed consolidated financial statements include the accounts of Harvard Apparatus Regenerative Technology and its subsidiaries; Harvard Apparatus Regenerative Technology Limited (Hong Kong), Harvard Apparatus Regenerative Technology (Hangzhou) Limited (China), and Harvard Apparatus Regenerative Technology GmbH (Germany). All intercompany balances and transactions have been eliminated in consolidation.
Basis of Presentation
The condensed consolidated financial statements reflect the Company’s financial position, results of operations and comprehensive loss and cash flows in conformity with accounting principles generally accepted in the United States, or U.S. GAAP. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Form 10-K for the fiscal year ended December 31, 2024.
Use of Estimates
The process of preparing condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Such estimates include, but are not limited to, share-based compensation, valuation of warrant liability, accrued expenses and the valuation allowance for deferred income taxes. Actual results could differ from those estimates.
Revenue
The Company recognizes revenue in accordance with Financial Accounting Standards Board (“FASB”) ASC 606, Revenue from Contracts with Customers. The Company offers consumer products primarily through a third-party online store. Revenue is recognized at a point in time when control of the goods is transferred to the customer, which generally occurs upon the delivery to the customer. For any company direct sales to customers, revenue is recognized at a point in time upon shipment of product or hand-delivery to customer. In October 2024, the Company entered into an exclusive distribution agreement (the “Distribution Agreement”) with Health Regen, Inc., of Pittsfield, MA (“Health Regen”). Pursuant to the Distribution Agreement, the Company granted Health Regen exclusive distribution rights to all of its Consumer Health Products globally. For any sales to distributors, revenue is recognized when control of the goods is transferred to the distributor, which is either upon shipment or upon the completion of production by third party manufacturers, depending on the contract terms. Revenue also excludes any amounts collected on behalf of third parties, including sales and indirect taxes.
The Company identifies a performance obligation as distinct if both the following criteria are true: the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer and the entity’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract. Determining the standalone selling price (“SSP”) and allocation of consideration from a contract to the individual performance obligations, and the appropriate timing of revenue recognition, is the result of significant qualitative and quantitative judgments. Management considers a variety of factors such as historical sales, usage rates, costs, and expected margin, which may vary over time depending upon the unique facts and circumstances related to each performance obligation in making these estimates. While changes in the allocation of the SSP between performance obligations will not affect the amount of total revenue recognized for a particular contract, any material changes could impact the timing of revenue recognition, which would have a material effect on the Company’s financial position and result of operations. This is because the contract consideration is allocated to each performance obligation, delivered or undelivered, at the inception of the contract based on the SSP of each distinct performance obligation.
Cost of Sales
Cost of sales primarily consists of the purchase price of consumer products, taxes, inbound and outbound shipping costs. Shipping costs to receive products from our suppliers are recognized as cost of sales when incurred. E-commerce processing and related transaction costs, including those associated with seller transactions, are classified in sales and marketing on our condensed consolidated statements of operations and comprehensive loss.
Research and Development
Research and development costs are expensed as incurred.
Sales and Marketing
Sales and marketing costs include advertising and payroll and related expenses for personnel engaged in marketing and selling activities. In October 2024, the Company entered into the Distribution Agreement with Health Regen, pursuant to which the Company granted Health Regen exclusive distribution rights to all of its Consumer Health Products globally. The initial term of the Distribution Agreement is from November 1, 2024 through December 31, 2030.
General and Administrative
General and administrative expenses primarily consist of costs for corporate functions, including payroll and related expenses; facilities and equipment expenses, such as depreciation and amortization expense and rent; and professional fees.
Segment Information
The Company manages its operations as two separate operating segments for the purposes of assessing performance and making operating decisions. The Company has one operating unit focused on the development and commercialization of therapies to treat cancers, injuries, and birth defects of the gastro-intestinal tract and the airways. The other operating unit is focused on personal healthcare through dietary supplements. The Company has determined that its chief executive officer is the chief operating decision maker (the “CODM”). The CODM reviews separate discrete financial information presented by operating segment. Resource allocation decisions are made by the CODM based on operating segment cash used in operations, revenues and net income (loss).
Cash Concentrations
The Company maintains its cash balances with a financial institution in federally insured accounts and may periodically have cash balances in excess of insurance limits. The Company maintains its accounts with financial institutions with a high credit rating. The Company has not experienced any losses to date and believes that it is not exposed to any significant credit risk on cash.
Cash and Cash Equivalents
The Company considers all highly liquid investments with a maturity of three months or less at the date of purchase to be cash equivalents. The Company currently invests available cash in money market funds.
Accounts Receivable
Allowances for credit losses are provided for estimated amounts of accounts receivable which may not be collected. At September 30, 2025 and December 31, 2024, we determined that no allowance for credit losses against accounts receivable was necessary. Advance payment is required under standard terms.
Inventory
Inventory, consisting of products available for sale, are primarily accounted for using the first-in, first-out method, and are valued at the lower of cost and net realizable value. This valuation requires us to make judgments, based on currently available information, about the likely method of disposition, such as through sales to individual customers, returns to product vendors, or liquidations, and expected recoverable values of each disposition category.
Long-term Prepaid Contracts
The Company has contracted with partners relating to its clinical trial activities. Upon execution of the contracts, the Company made initial deposits of $1.2 million in connection with a clinical trial contract and will be applied against final invoices which are more than a year away. The deposits will be recorded as expense when the clinical trial is substantially completed. Costs for the clinical trial activities throughout the Company’s clinical trial under these contracts are recognized as expense and payable based on costs incurred. As of September 30, 2025, the Company’s clinical trial partner applied approximately $0.6 million of these deposits against invoices reducing the long-term prepaid contracts balance to $0.6 million. In addition to the clinical trial deposits, the company has $0.1 million in other deposits paid to its landlord as a security deposit and to a university for future esophageal implant production. The deposits are not expected to be expensed within the next twelve months and are therefore classified as long term.
Property, Plant and Equipment
Property, plant and equipment are recorded at cost and depreciated using the straight-line method over the estimated useful lives of the assets as follows:
Maintenance and repairs are charged to expense as incurred, while any additions or improvements are capitalized.
Deferred Revenue
Deferred revenue represents advance payments received from customers for goods or services to be delivered in future periods. These payments are initially recorded as liabilities and recognized as revenue when the related goods or services are provided. As of September 30, 2025, the Company had deferred revenue of $128,000, which primarily consists of advance payments for consumer health products. The Company expects to recognize this revenue within the next fiscal quarter, as the performance obligations are satisfied.
Management regularly reviews the deferred revenue balance to ensure that revenue is recognized in accordance with the Company's revenue recognition policy and applicable accounting standards.
Foreign Currency
Assets and liabilities of non-U.S. operations where the functional currency is other than the U.S. dollar are translated from the functional currency into U.S. dollars at year end exchange rates, and revenues and expenses are translated at average rates prevailing during the year. Resulting translation adjustments are accumulated as part of accumulated other comprehensive loss. Transaction gains or losses are recognized in income or loss in the period in which they occur.
Net Loss Per Share
Basic net loss per share is calculated by dividing net loss applicable to common stockholders by the weighted-average number of shares outstanding during the period, without consideration for common stock equivalents. Diluted net loss per share is calculated by adjusting the weighted-average number of shares outstanding for the dilutive effect of common stock equivalents outstanding for the period, determined using the if-converted method. For purposes of the diluted net loss per share calculation, warrants to purchase the Company’s common stock, par value $0.01 per share ( the “Common Stock”) and stock options are considered to be common stock equivalents, but have been excluded from the calculation of diluted net loss per share, as their effect would be anti-dilutive for all periods presented. Therefore, basic and diluted net loss per share applicable to common stockholders were the same for all periods presented.
Concentration of Credit Risk
Financial investments that potentially subject the Company to credit risk consist of cash. The Company has all cash deposited at accredited financial institutions. Bank accounts in the United States are insured by the Federal Deposit Insurance Corporation up to $250,000. The Company does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships.
For the three and nine months ended September 30, 2025, Health Regen accounted for approximately 95% and 96% of total product revenue, respectively. Health Regen was the only customer to account for more than 10% of total accounts receivable as of both September 30, 2025 and December 31, 2024. There were no customers that accounted for more than 10% in product revenue during the three and nine months ended September 30, 2024.
Unaudited Interim Financial Information
The accompanying interim condensed consolidated balance sheet as of September 30, 2025, condensed consolidated interim statements of operations and comprehensive loss and condensed consolidated statements of stockholders’ equity for the three and nine months ended September 30, 2025 and 2024, and cash flows for the nine months ended September 30, 2025 and 2024 are unaudited. The interim unaudited condensed consolidated financial statements have been prepared in accordance with U.S. GAAP on the same basis as the annual audited consolidated financial statements and, in the opinion of management, reflect all adjustments necessary for a fair statement of the Company’s financial position as of September 30, 2025, its condensed consolidated results of operations and stockholders’ equity for the three and nine months ended September 30, 2025 and 2024, and cash flows for the nine months ended September 30, 2025 and 2024. The financial data and other information disclosed in these notes related to the three and nine months ended September 30, 2025 and 2024 are unaudited. The results for the three and nine months ended September 30, 2025 are not necessarily indicative of results to be expected for the year ending December 31, 2025, any other interim periods or any future year or period.
Recent Accounting Pronouncements
Accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Company’s condensed consolidated financial statements upon adoption.
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The objective of ASU 2023-09 is to enhance disclosures related to income taxes, including specific thresholds for inclusion within the tabular disclosure of income tax rate reconciliation and specified information about income taxes paid. ASU 2023-09 is effective for public companies starting in annual periods beginning after December 15, 2024. The Company is currently evaluating the impact that ASU 2023-09 will have on its condensed consolidated financial statements.
In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. ASU 2024-03 improves disclosures about a public business entity’s expenses by requiring disaggregated disclosures of certain types of expenses, including purchases of inventory, employee compensation, depreciation, intangible amortization and depletion, as applicable, for each income statement caption that includes those expenses. In addition, the standard will require entities to define and disclose total selling expenses. The standard is effective for public business entities for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted, and entities may apply the standard prospectively or retrospectively. The Company is currently evaluating the impact of adopting this standard on its condensed consolidated financial statements and related disclosures.
In July 2025, the FASB issued ASU 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. This update provides a practical expedient and an accounting policy election for estimating expected credit losses on current accounts receivable and contract assets arising under ASC 606. The Company has elected to apply the practical expedient, which assumes that current conditions as of the balance sheet date remain unchanged for the remaining life of the asset. Given the immaterial nature of the Company’s accounts receivable and contract assets, the adoption of ASU 2025-05 is not expected to have a material impact on the Company’s condensed consolidated financial statements and related disclosures. The amendments are effective for fiscal years beginning after December 15, 2025, with early adoption permitted. The Company intends to adopt the guidance in the first quarter of fiscal year 2026.

4. Capital Stock
Preferred Stock
The Company has authorized a total of 2,000,000 shares of preferred stock, par value $0.01 per share (the “Preferred Stock”), none of which were outstanding at September 30, 2025 and December 31, 2024. The Company’s Board of Directors (the “Board”) has the authority to issue Preferred Stock and to determine the rights, preferences, privileges, and restrictions, including voting rights.
Common Stock
On July 11, 2025, the Company entered into securities purchase agreements with certain investors each named therein (the “July Investor,” and collectively the “July Investors”) pursuant to which each of the July Investors agreed to purchase in a private placement an aggregate of 1,250,000 shares of Common Stock for the aggregate gross proceeds of approximately $2.0 million at a purchase price per share of $1.60.
On August 19, 2024, the Company entered into a securities purchase agreement with an investor (the “August Investor”) pursuant to which the August Investor agreed to purchase in a private placement an aggregate of 1,388,888 shares of Common Stock for the aggregate purchase price of approximately $5.0 million at a purchase price per share of $3.60.
The August Purchase Agreement required the Company to increase the size of the Board by one member, to appoint a designee selected by the August Investor to the Board, and to take certain actions to ensure that the designee remains on the Board. The Company also agreed to use its reasonable best efforts to obtain approval from its stockholders at the next annual meeting of stockholders to amend the Company’s Amended and Restated Certificate of Incorporation (the “Charter”) to eliminate classification of directors and to amend the Charter and the Company’s Third Amended and Restated Bylaws to permit special stockholder meetings to be called by holders of at least 35% of the Company’s voting power. The Company held its annual shareholder meeting on June 20, 2025, during which shareholders approved the actions outlined in the August Purchase Agreement.
On April 15, 2024, the Company entered into securities purchase agreements with certain investors each named therein (each, an “April Investor,” and collectively the “April Investors”) pursuant to which each of the April Investors agreed to purchase in a private placement an aggregate of 367,767 shares of Common Stock for the aggregate gross proceeds of approximately $1.5 million at a purchase price per share of $4.03.
Pursuant to the April Purchase Agreements, if the Company closes an equity financing in a registered public offering of its securities on or before six (6) months from the date of the April Purchase Agreements, and the public offering price per share was less than the per share purchase price of the 2024 Private Placement, then the Company shall promptly following such closing issue to each Investor additional shares of Common Stock in an amount equal to the difference between (i) the shares issued in the 2024 Private Placement, and (ii) result of dividing (a) the subscription amount for each April Purchase Agreement, by (b) the public offering per share. As of October 15, 2024, being six months following the date of the April Purchase Agreements, the Company had not completed an equity financing through a registered public offering of its securities since April 15, 2024 and thus this additional issuance requirement is no longer applicable.
Warrants
The Company had 898,622 warrants to purchase Common Stock outstanding as of September 30, 2025 and December 31, 2024 with a weighted-average exercise price of $5.33.

5. Share-Based Compensation
Harvard Apparatus Regenerative Technology Amended and Restated Equity Incentive Plan
The Company maintains the Amended and Restated Equity Incentive Plan, or the Plan, for the benefit of certain officers, employees, non-employee directors, and other key persons (including consultants and advisory board members). All options and awards granted under the Plan consist of shares of Common Stock. The Company’s policy is to issue stock available from its registered but unissued stock pool through its transfer agent to satisfy stock option exercises and the vesting of restricted stock units. The vesting period for awards is generally four years and the contractual life is ten years. Canceled and forfeited options and awards are available to be reissued under the Plan.
As of September 30, 2025, the Company’s Plan has 9,098,000 authorized shares to be issued under the Plan. There were 4,370,364 shares available for issuance as of September 30, 2025.
The following table summarizes information concerning options outstanding and exercisable:
The Company’s outstanding stock options include 993,835 performance-based awards that have vesting provisions subject to the achievement of certain business milestones. Total unrecognized compensation expense for the performance-based awards is approximately $3.4 million. The Company recognized approximately $7,800 and $44,000 in share-based compensation during the three and nine months ended September 30, 2025, respectively, and $0.02 million and $0.10 million in share-based compensation during the three and nine months ended September 30, 2024, respectively, as a result of certain milestone achievements for these awards have been deemed probable for accounting purposes.
Aggregate intrinsic value for outstanding options as of September 30, 2025 was approximately $0.3 million and calculated as the difference between the Company’s closing stock price of $1.98 per share as of September 30, 2025 and the weighted average exercise price of $3.72. As of September 30, 2025, unrecognized compensation cost related to unvested non-performance-based awards amounted to $1.2 million, which will be recognized over a weighted-average period of 0.8 years.
The Company uses the Black-Scholes option pricing model to value its stock options. The weighted average assumptions for valuing options granted during the nine months ended September 30, 2025 and 2024 were as follows:
The Company recorded share-based compensation expense in the following expense categories of its condensed consolidated statements of operations and comprehensive loss:

| Segment Reporting Disclosure [Text Block] |
10. Segments
The Company’s CODM is its Chief Executive Officer. The Company’s CODM evaluates the operating results of the Company’s reportable segments based on cash used in operations, revenues and net income (loss).
The Company follows the accounting guidance of ASC 280, Segment Reporting (“ASC 280”). Reportable operating segments are determined based on the management approach. The management approach, as defined by ASC 280, is based on the way that the CODM organizes the segments within an enterprise for making operating decisions and assessing performance. While the Company’s results of operations are primarily reviewed on a consolidated basis, the CODM manages the enterprise in two reportable segments, each with different operating and potential revenue generating characteristics.
The Company has two operating and reportable segments: (i) Regenerative Biotech focused on the development of regenerative medicine treatments with operations currently in the United States and (ii) Consumer Health Products relating to consumer health products with operations currently in Asia. All of the Company’s revenue was generated in Asia for the three and nine months ended September 30, 2025 and 2024. The following tables represent selected financial information for our segments:

Significant Accounting Policies (Policies) |
9 Months Ended | |||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Sep. 30, 2025 | ||||||||||||||||
| Accounting Policies [Abstract] | ||||||||||||||||
| Consolidation, Policy [Policy Text Block] | Principles of Consolidation
The condensed consolidated financial statements include the accounts of Harvard Apparatus Regenerative Technology and its subsidiaries; Harvard Apparatus Regenerative Technology Limited (Hong Kong), Harvard Apparatus Regenerative Technology (Hangzhou) Limited (China), and Harvard Apparatus Regenerative Technology GmbH (Germany). All intercompany balances and transactions have been eliminated in consolidation.
|
|||||||||||||||
| Basis of Accounting, Policy [Policy Text Block] | Basis of Presentation
The condensed consolidated financial statements reflect the Company’s financial position, results of operations and comprehensive loss and cash flows in conformity with accounting principles generally accepted in the United States, or U.S. GAAP. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Form 10-K for the fiscal year ended December 31, 2024.
|
|||||||||||||||
| Use of Estimates, Policy [Policy Text Block] | Use of Estimates
The process of preparing condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Such estimates include, but are not limited to, share-based compensation, valuation of warrant liability, accrued expenses and the valuation allowance for deferred income taxes. Actual results could differ from those estimates.
|
|||||||||||||||
| Revenue [Policy Text Block] | Revenue
The Company recognizes revenue in accordance with Financial Accounting Standards Board (“FASB”) ASC 606, Revenue from Contracts with Customers. The Company offers consumer products primarily through a third-party online store. Revenue is recognized at a point in time when control of the goods is transferred to the customer, which generally occurs upon the delivery to the customer. For any company direct sales to customers, revenue is recognized at a point in time upon shipment of product or hand-delivery to customer. In October 2024, the Company entered into an exclusive distribution agreement (the “Distribution Agreement”) with Health Regen, Inc., of Pittsfield, MA (“Health Regen”). Pursuant to the Distribution Agreement, the Company granted Health Regen exclusive distribution rights to all of its Consumer Health Products globally. For any sales to distributors, revenue is recognized when control of the goods is transferred to the distributor, which is either upon shipment or upon the completion of production by third party manufacturers, depending on the contract terms. Revenue also excludes any amounts collected on behalf of third parties, including sales and indirect taxes.
The Company identifies a performance obligation as distinct if both the following criteria are true: the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer and the entity’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract. Determining the standalone selling price (“SSP”) and allocation of consideration from a contract to the individual performance obligations, and the appropriate timing of revenue recognition, is the result of significant qualitative and quantitative judgments. Management considers a variety of factors such as historical sales, usage rates, costs, and expected margin, which may vary over time depending upon the unique facts and circumstances related to each performance obligation in making these estimates. While changes in the allocation of the SSP between performance obligations will not affect the amount of total revenue recognized for a particular contract, any material changes could impact the timing of revenue recognition, which would have a material effect on the Company’s financial position and result of operations. This is because the contract consideration is allocated to each performance obligation, delivered or undelivered, at the inception of the contract based on the SSP of each distinct performance obligation.
|
|||||||||||||||
| Cost of Goods and Service [Policy Text Block] | Cost of Sales
Cost of sales primarily consists of the purchase price of consumer products, taxes, inbound and outbound shipping costs. Shipping costs to receive products from our suppliers are recognized as cost of sales when incurred. E-commerce processing and related transaction costs, including those associated with seller transactions, are classified in sales and marketing on our condensed consolidated statements of operations and comprehensive loss.
|
|||||||||||||||
| Research and Development Expense, Policy [Policy Text Block] | Research and Development
Research and development costs are expensed as incurred.
|
|||||||||||||||
| Advertising Cost [Policy Text Block] | Sales and Marketing
Sales and marketing costs include advertising and payroll and related expenses for personnel engaged in marketing and selling activities. In October 2024, the Company entered into the Distribution Agreement with Health Regen, pursuant to which the Company granted Health Regen exclusive distribution rights to all of its Consumer Health Products globally. The initial term of the Distribution Agreement is from November 1, 2024 through December 31, 2030.
|
|||||||||||||||
| Selling, General and Administrative Expenses, Policy [Policy Text Block] | General and Administrative
General and administrative expenses primarily consist of costs for corporate functions, including payroll and related expenses; facilities and equipment expenses, such as depreciation and amortization expense and rent; and professional fees.
|
|||||||||||||||
| Segment Reporting, Policy [Policy Text Block] | Segment Information
The Company manages its operations as two separate operating segments for the purposes of assessing performance and making operating decisions. The Company has one operating unit focused on the development and commercialization of therapies to treat cancers, injuries, and birth defects of the gastro-intestinal tract and the airways. The other operating unit is focused on personal healthcare through dietary supplements. The Company has determined that its chief executive officer is the chief operating decision maker (the “CODM”). The CODM reviews separate discrete financial information presented by operating segment. Resource allocation decisions are made by the CODM based on operating segment cash used in operations, revenues and net income (loss).
|
|||||||||||||||
| Cash and Cash Equivalents, Policy [Policy Text Block] | Cash Concentrations
The Company maintains its cash balances with a financial institution in federally insured accounts and may periodically have cash balances in excess of insurance limits. The Company maintains its accounts with financial institutions with a high credit rating. The Company has not experienced any losses to date and believes that it is not exposed to any significant credit risk on cash.
Cash and Cash Equivalents
The Company considers all highly liquid investments with a maturity of three months or less at the date of purchase to be cash equivalents. The Company currently invests available cash in money market funds.
|
|||||||||||||||
| Accounts Receivable [Policy Text Block] | Accounts Receivable
Allowances for credit losses are provided for estimated amounts of accounts receivable which may not be collected. At September 30, 2025 and December 31, 2024, we determined that no allowance for credit losses against accounts receivable was necessary. Advance payment is required under standard terms.
|
|||||||||||||||
| Inventory, Policy [Policy Text Block] | Inventory
Inventory, consisting of products available for sale, are primarily accounted for using the first-in, first-out method, and are valued at the lower of cost and net realizable value. This valuation requires us to make judgments, based on currently available information, about the likely method of disposition, such as through sales to individual customers, returns to product vendors, or liquidations, and expected recoverable values of each disposition category.
|
|||||||||||||||
| Long Term Prepaid Contracts [Policy Text Block] | Long-term Prepaid Contracts
The Company has contracted with partners relating to its clinical trial activities. Upon execution of the contracts, the Company made initial deposits of $1.2 million in connection with a clinical trial contract and will be applied against final invoices which are more than a year away. The deposits will be recorded as expense when the clinical trial is substantially completed. Costs for the clinical trial activities throughout the Company’s clinical trial under these contracts are recognized as expense and payable based on costs incurred. As of September 30, 2025, the Company’s clinical trial partner applied approximately $0.6 million of these deposits against invoices reducing the long-term prepaid contracts balance to $0.6 million. In addition to the clinical trial deposits, the company has $0.1 million in other deposits paid to its landlord as a security deposit and to a university for future esophageal implant production. The deposits are not expected to be expensed within the next twelve months and are therefore classified as long term.
|
|||||||||||||||
| Property, Plant and Equipment, Policy [Policy Text Block] | Property, Plant and Equipment
Property, plant and equipment are recorded at cost and depreciated using the straight-line method over the estimated useful lives of the assets as follows:
Maintenance and repairs are charged to expense as incurred, while any additions or improvements are capitalized.
|
|||||||||||||||
| Revenue from Contract with Customer [Policy Text Block] | Deferred Revenue
Deferred revenue represents advance payments received from customers for goods or services to be delivered in future periods. These payments are initially recorded as liabilities and recognized as revenue when the related goods or services are provided. As of September 30, 2025, the Company had deferred revenue of $128,000, which primarily consists of advance payments for consumer health products. The Company expects to recognize this revenue within the next fiscal quarter, as the performance obligations are satisfied.
Management regularly reviews the deferred revenue balance to ensure that revenue is recognized in accordance with the Company's revenue recognition policy and applicable accounting standards.
|
|||||||||||||||
| Foreign Currency Transactions and Translations Policy [Policy Text Block] | Foreign Currency
Assets and liabilities of non-U.S. operations where the functional currency is other than the U.S. dollar are translated from the functional currency into U.S. dollars at year end exchange rates, and revenues and expenses are translated at average rates prevailing during the year. Resulting translation adjustments are accumulated as part of accumulated other comprehensive loss. Transaction gains or losses are recognized in income or loss in the period in which they occur.
|
|||||||||||||||
| Earnings Per Share, Policy [Policy Text Block] | Net Loss Per Share
Basic net loss per share is calculated by dividing net loss applicable to common stockholders by the weighted-average number of shares outstanding during the period, without consideration for common stock equivalents. Diluted net loss per share is calculated by adjusting the weighted-average number of shares outstanding for the dilutive effect of common stock equivalents outstanding for the period, determined using the if-converted method. For purposes of the diluted net loss per share calculation, warrants to purchase the Company’s common stock, par value $0.01 per share ( the “Common Stock”) and stock options are considered to be common stock equivalents, but have been excluded from the calculation of diluted net loss per share, as their effect would be anti-dilutive for all periods presented. Therefore, basic and diluted net loss per share applicable to common stockholders were the same for all periods presented.
|
|||||||||||||||
| Concentration Risk, Credit Risk, Policy [Policy Text Block] | Concentration of Credit Risk
Financial investments that potentially subject the Company to credit risk consist of cash. The Company has all cash deposited at accredited financial institutions. Bank accounts in the United States are insured by the Federal Deposit Insurance Corporation up to $250,000. The Company does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships.
For the three and nine months ended September 30, 2025, Health Regen accounted for approximately 95% and 96% of total product revenue, respectively. Health Regen was the only customer to account for more than 10% of total accounts receivable as of both September 30, 2025 and December 31, 2024. There were no customers that accounted for more than 10% in product revenue during the three and nine months ended September 30, 2024.

|||||||||||||||
| Unaudited Interim Financial Information (Policy Text Block) | Unaudited Interim Financial Information
The accompanying interim condensed consolidated balance sheet as of September 30, 2025, condensed consolidated interim statements of operations and comprehensive loss and condensed consolidated statements of stockholders’ equity for the three and nine months ended September 30, 2025 and 2024, and cash flows for the nine months ended September 30, 2025 and 2024 are unaudited. The interim unaudited condensed consolidated financial statements have been prepared in accordance with U.S. GAAP on the same basis as the annual audited consolidated financial statements and, in the opinion of management, reflect all adjustments necessary for a fair statement of the Company’s financial position as of September 30, 2025, its condensed consolidated results of operations and stockholders’ equity for the three and nine months ended September 30, 2025 and 2024, and cash flows for the nine months ended September 30, 2025 and 2024. The financial data and other information disclosed in these notes related to the three and nine months ended September 30, 2025 and 2024 are unaudited. The results for the three and nine months ended September 30, 2025 are not necessarily indicative of results to be expected for the year ending December 31, 2025, any other interim periods or any future year or period.

| New Accounting Pronouncements, Policy [Policy Text Block] | Recent Accounting Pronouncements
Accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Company’s condensed consolidated financial statements upon adoption.
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The objective of ASU 2023-09 is to enhance disclosures related to income taxes, including specific thresholds for inclusion within the tabular disclosure of income tax rate reconciliation and specified information about income taxes paid. ASU 2023-09 is effective for public companies starting in annual periods beginning after December 15, 2024. The Company is currently evaluating the impact that ASU 2023-09 will have on its condensed consolidated financial statements.
In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. ASU 2024-03 improves disclosures about a public business entity’s expenses by requiring disaggregated disclosures of certain types of expenses, including purchases of inventory, employee compensation, depreciation, intangible amortization and depletion, as applicable, for each income statement caption that includes those expenses. In addition, the standard will require entities to define and disclose total selling expenses. The standard is effective for public business entities for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted, and entities may apply the standard prospectively or retrospectively. The Company is currently evaluating the impact of adopting this standard on its condensed consolidated financial statements and related disclosures.
In July 2025, the FASB issued ASU 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. This update provides a practical expedient and an accounting policy election for estimating expected credit losses on current accounts receivable and contract assets arising under ASC 606. The Company has elected to apply the practical expedient, which assumes that current conditions as of the balance sheet date remain unchanged for the remaining life of the asset. Given the immaterial nature of the Company’s accounts receivable and contract assets, the adoption of ASU 2025-05 is not expected to have a material impact on the Company’s condensed consolidated financial statements and related disclosures. The amendments are effective for fiscal years beginning after December 15, 2025, with early adoption permitted. The Company intends to adopt the guidance in the first quarter of fiscal year 2026.
