Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies *Basis of Presentation and Unaudited Condensed Interim Financial Information* The accompanying unaudited condensed interim financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules and regulations, certain footnotes or other financial information normally included in unaudited condensed interim financial statements prepared in accordance with GAAP have been condensed or omitted. The unaudited condensed interim financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal, recurring adjustments that are necessary to present fairly the Company’s results for the interim periods presented. The condensed balance sheet as of December 31, 2024, is derived from the Company’s audited financial statements. The results of operations for the three months ended June 30, 2025, are not necessarily indicative of the results to be expected for the year ending December 31, 2025, or for any other future annual or interim period. Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting Standards Codification (“ASC”) and as amended by Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). There have been no material changes to the significant accounting policies during the six months ended June 30, 2025 from those previously disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on April 1, 2025, other than the accounting policies adopted in connection with the Company’s February 2025 Offering as described below. *February 2025 Offering* The Company evaluated the underwriter warrants Common issued in connection with the February 2025 Offering in accordance with ASC Topic 480, Distinguishing Liabilities from Equity and ASC 815-40, Derivatives and Hedging – Contracts in Entity’s Own Entity and concluded that the underwriter warrants are freestanding financial instruments, meeting ASC Topic 480’s criteria for legal detachment and separate exercisability from the common stock. The underwriter warrants are classified as equity, not liabilities, as they do not embody obligations for cash settlement or issuance of variable shares. The initial recognition involves recording proceeds in Additional Paid-In Capital (“APIC”) with issuance costs as contra-equity. For diluted Earnings Per Share (“EPS”), the treasury stock method applies, as the underwriter warrants are dilutive but not participating securities before exercise, ensuring no impact on basic EPS until shares are issued. *Risks and Uncertainties* The Company and its business are subject to a number of significant risks associated with clinical-stage and early commercial stage life science companies, including the risks associated with (i) its relatively early stage commercialization efforts for RenovoCath, (ii) the development of IAG or other product candidates that must receive regulatory approval before market launch, (iii) possible failure of current or future preclinical studies or clinical trials, (iv) dependence on key third parties such as device manufacturers and providers of clinical trial administration services; (v) the need to obtain and maintain insurance coding for its products and product candidates, (vi) dependence on key officer and employees, (vii) competition from larger and more established companies, (viii) obtaining and maintaining intellectual property protections, (ix) changes in the Company’s technology or industry, (x) volatility in the public capital markets, (xi) the Company’s ability to obtain adequate financing when needed to support the Company’s business plan, (xii) the ability to attract and retain additional qualified personnel to manage the anticipated growth of the Company and (xiii) general economic and political conditions. *Use of Estimates* The preparation of condensed interim financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenue, income and expenses as well as the disclosure of contingent assets and liabilities, at the date of the condensed interim financial statements during the reporting periods. In preparing these condensed interim financial statements, management has made its best estimates and judgments of certain amounts included in the condensed interim financial statements. Significant estimates and assumptions made in the accompanying condensed interim financial statements include, but are not limited to, accruals of certain liabilities, including clinical trial accruals and other contingences, the valuation of financial instruments, the fair value of the Company’s common stock and the fair value of options granted under the Company’s equity incentive plan. On an ongoing basis, the Company evaluates its estimates, including those related to the fair values of assets, stock-based compensation, clinical trial accruals and other contingencies. Management bases its estimates on historical experience or on various other assumptions that it believes to be reasonable under the circumstances. Actual results could differ materially from these estimates. *Emerging Growth Company and Smaller Reporting Company Status* The Company is an emerging growth company as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) and may take advantage of reduced reporting requirements that are otherwise applicable to public companies. Section 107 of the JOBS Act exempts emerging growth companies from complying with new or revised financial accounting standards until private companies are required to comply with those standards. The Company has elected to use the extended transition period for complying with new or revised accounting standards. The Company expects to lose its status as an emerging growth company status as of December 31, 2026, the last day of the fiscal year following the fifth anniversary of the closing its August 2021 initial public offering. The Company is also a “smaller reporting company,” as defined in Rule 12b-2 of the Exchange Act. If the Company is a smaller reporting company at the time the Company ceases to be an emerging growth company, the Company may continue to rely on exemptions from certain disclosure requirements that are available to smaller reporting companies. Specifically, as a smaller reporting company, the Company may choose to present only the two most recent fiscal years of audited financial statements in its Annual Report on Form 10-K and, like emerging growth companies, smaller reporting companies have reduced disclosure obligations regarding executive compensation. From time to time, new accounting pronouncements are issued by the FASB or other standard-setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed, the impact of recently issued standards that are not yet effective will not have a material impact on the Company’s financial position or results of operations upon adoption. Recent Accounting Pronouncements *Accounting Pronouncements Not Yet Adopted* In December 2023, FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU 2023-09). ASU 2023-09 modifies the rules on income tax disclosures to enhance the transparency and decision-usefulness of income tax disclosures, particularly in the rate reconciliation table and disclosures about income taxes paid. The amendments are intended to address investors’ requests for income tax disclosures that provide more information to help them better understand an entity’s exposure to potential changes in tax laws and the ensuing risks and opportunities and to assess income tax information that affects cash flow forecasts and capital allocation decisions. The guidance also eliminates certain existing disclosure requirements related to uncertain tax positions and unrecognized deferred tax liabilities. The guidance is effective for all entities for annual periods beginning after December 15, 2025. All entities should apply the guidance prospectively but have the option to apply it retrospectively. Early adoption is permitted. The Company is continuing to assess the timing of adoption and the potential impacts of ASU 2023-09 on the condensed interim financial statements and related disclosures. In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40) (ASU 2024-03). ASU 2024-03 modifies the rules on income statement disclosures to enhance the transparency of and include more detailed information about the types of expenses, including purchases of inventory, employee compensation, depreciation, amortization, and depletion, in commonly presented expense captions such as cost of sales, research and development, and selling, general and administrative expenses. The amendments are intended to address investors’ requests for income statement expense disclosures that provide more information to help them better understand the components of an entity’s expenses, make their own judgments about the entity’s performance, and more accurately forecast expenses, and enable investors to better assess an entity’s prospects for future cash flows. It will also provide contextual information for an entity’s presentation and consideration of management’s discussion and analysis of financial position and results of operations. The guidance is effective for all entities for annual periods beginning after December 15, 2026. All entities should apply the guidance prospectively but have the option to apply it retrospectively. Early adoption is permitted. The Company is continuing to assess the timing of adoption and the potential impacts of ASU 2024-03 on the condensed interim financial statements and related disclosures. The Company continues to monitor new accounting pronouncements issued by the FASB and does not believe any accounting pronouncements issued through the date of this report will have a material impact on the Company’s condensed interim financial statements.

2. Summary of Significant Accounting Policies

Basis of Presentation and Unaudited Condensed Interim Financial Information

The accompanying unaudited condensed interim financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) for interim reporting.

Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting Standards Codification (“ASC”) and as amended by Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”).

There have been no material changes to the significant accounting policies during the six months ended June 30, 2025 from those previously disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on April 1, 2025, other than the accounting policies adopted in connection with the Company’s February 2025 Offering as described below.

February 2025 Offering

The Company evaluated the underwriter warrants Common issued in connection with the February 2025 Offering in accordance with ASC Topic 480, Distinguishing Liabilities from Equity and ASC 815-40, Derivatives and Hedging – Contracts in Entity’s Own Entity and concluded that the underwriter warrants are freestanding financial instruments, meeting ASC Topic 480’s criteria for legal detachment and separate exercisability from the common stock.

The initial recognition involves recording proceeds in Additional Paid-In Capital (“APIC”) with issuance costs as contra-equity. For diluted Earnings Per Share (“EPS”), the treasury stock method applies, as the underwriter warrants are dilutive but not participating securities before exercise, ensuring no impact on basic EPS until shares are issued.

Risks and Uncertainties

The Company and its business are subject to a number of significant risks associated with clinical-stage and early commercial stage life science companies, including the risks associated with (i) its relatively early stage commercialization efforts for RenovoCath, (ii) the development of IAG or other product candidates that must receive regulatory approval before market launch, (iii) possible failure of current or future preclinical studies or clinical trials, (iv) dependence on key third parties such as device manufacturers and providers of clinical trial administration services; (v) the need to obtain and maintain insurance coding for its products and product candidates, (vi) dependence on key officer and employees, (vii) competition from larger and more established companies, (viii) obtaining and maintaining intellectual property protections, (ix) changes in the Company’s technology or industry, (x) volatility in the public capital markets, (xi) the Company’s ability to obtain adequate financing when needed to support the Company’s business plan, (xii) the ability to attract and retain additional qualified personnel to manage the anticipated growth of the Company and (xiii) general economic and political conditions.

Use of Estimates

The preparation of condensed interim financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenue, income and expenses as well as the disclosure of contingent assets and liabilities, at the date of the condensed interim financial statements during the reporting periods. In preparing these condensed interim financial statements, management has made its best estimates and judgments of certain amounts included in the condensed interim financial statements.

On an ongoing basis, the Company evaluates its estimates, including those related to the fair values of assets, stock-based compensation, clinical trial accruals and other contingencies. Management bases its estimates on historical experience or on various other assumptions that it believes to be reasonable under the circumstances. Actual results could differ materially from these estimates.

Emerging Growth Company and Smaller Reporting Company Status

The Company is an emerging growth company as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) and may take advantage of reduced reporting requirements that are otherwise applicable to public companies. Section 107 of the JOBS Act exempts emerging growth companies from complying with new or revised financial accounting standards until private companies are required to comply with those standards. The Company has elected to use the extended transition period for complying with new or revised accounting standards. The Company expects to lose its status as an emerging growth company status as of December 31, 2026, the last day of the fiscal year following the fifth anniversary of the closing its August 2021 initial public offering.

The Company is also a “smaller reporting company,” as defined in Rule 12b-2 of the Exchange Act.

Specifically, as a smaller reporting company, the Company may choose to present only the two most recent fiscal years of audited financial statements in its Annual Report on Form 10-K and, like emerging growth companies, smaller reporting companies have reduced disclosure obligations regarding executive compensation.

From time to time, new accounting pronouncements are issued by the FASB or other standard-setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed, the impact of recently issued standards that are not yet effective will not have a material impact on the Company’s financial position or results of operations upon adoption.
