Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Principal Activities	1. Business and Principal Activities Description of Business RenovoRx, Inc. (the “Company,” “we,” “us,” “our” and similar terminology) was incorporated in the state of Delaware in December 2012 and operates from its headquarters in Los Altos, California. The Company is a clinical-stage biopharmaceutical company focused on developing novel precision oncology therapies based on a local drug delivery platform for high unmet medical need with a goal to improve therapeutic outcomes for cancer patients undergoing treatment. The Company’s patented Trans-Arterial Micro-Perfusion (“TAMP™”) therapy platform is designed to ensure precise therapeutic delivery to directly target tumors while potentially minimizing a therapy’s toxicities versus systemic intravenous therapy. The Company’s novel and patented approach to targeted treatment offers the potential for increased safety, tolerance, and improved efficacy. The Company’s Phase III lead product candidate, RenovoGem™, a novel oncology drug-device combination product, is being investigated under a U.S. new drug application that is regulated by the Food and Drug Administration’s (“FDA”) 21 CFR 312 pathway. RenovoGem is currently being evaluated for the treatment of locally advanced pancreatic cancer (“LPAC”) by the Center for Drug Evaluation and Research (the drug division of the FDA). RenovoGem utilizes RenovoCath, the Company’s FDA-cleared drug-delivery device, indicated for temporary vessel occlusion in applications including arteriography, preoperative occlusion, and chemotherapeutic drug infusion, in combination with gemcitabine ( chemotherapy) The Company is also actively exploring the use of TAMP to treat cancers beyond LAPC as well as other commercialization strategies for its technology. Liquidity and Capital Resources From the Company’s inception through June 30, 2024, it has raised an aggregate of $ 59.2 11.7 0.0001 The Company is in the pre-commercial stage and therefore has incurred significant losses and negative cash flows from operations since its inception. For the six months ended June 30, 2024, the Company reported a net loss of $ 3.5 44.9 The Company believes it will be able to raise additional required capital through debt financings, private or public equity financings, license agreements, collaborative agreements or other arrangements with other companies, or other sources of financing. There can be no assurance that such financing will be available or will be at terms acceptable to the Company. The inability to raise capital as and when needed would have a negative impact on the Company’s liquidity financial condition and its ability to pursue its business strategy. The Company will need to generate significant revenue to achieve profitability, and it may never do so. On November 10, 2022, the Company has filed an omnibus shelf registration statement on Form S-3 that provides for the aggregate offerings of up to $ 50.0 11.4 10.80 On April 3, 2023, the Company completed a registered direct offering (“RDO”) utilizing its shelf registration statement for the purchase and sale of 1,557,632 common 1,947,040 The aggregate gross proceeds from this offer were $ 5.0 4.4 0.4 0.2 On January 26, 2024, the Company completed a private placement to 92 6.1 0.7 6,133,414 6,133,414 five years 511,940 five years 0.99 1.22 On April 11, 2024, the Company completed another private placement offering to 172 11.1 9.7 1.2 0.2 6,960,864 951,500 0.0001 7,912,364 1.22 5 3,956,182 1.22 2 701,243 1.69 5 The accompanying financial statements have been prepared assuming that the Company will continue as a going concern and has reviewed the relevant conditions and events surrounding its ability to continue as a going concern including among others: historical losses, projected future results, negative cash flows from operations, including cash requirements for the upcoming year, funding capacity, net working capital, total stockholders’ equity and future access to capital. Based upon the Company’s current operating plan, management believes that its existing cash and cash equivalents as of the issuance of the accompanying unaudited condensed interim financial statements will be sufficient to allow the Company to fund operating, investing and financing cash flow needs for at least twelve months from such date. The accompanying unaudited condensed interim financial statements have been prepared assuming that the Company will continue as a going concern, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of business. The accompanying unaudited condensed interim financial statements do not reflect any adjustments relating to the recoverability and reclassifications of assets and liabilities that might be necessary if the Company is unable to continue as a going concern.

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, 2023, is derived from the Company’s audited financial statements. The results of operations for the three ended June 30, 2024, are not necessarily indicative of the results to be expected for the year ending December 31, 2023, 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 and as amended by Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). Summary of Significant Accounting Policies There have been no material changes to the significant accounting policies during the six months ended June 30, 2024 from those previously disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 filed with the SEC on April 1, 2024 (the “2023 Annual Report”). Risks and Uncertainties The Company is subject to a number of risks associated with companies at a similar stage, including the risks associated with the development of products that must receive regulatory approval before market launch, dependence on key individuals, competition from larger and more established companies, volatility of the industry, ability to obtain adequate financing to support the Company’s business plan, the ability to attract and retain additional qualified personnel to manage the anticipated growth of the Company and general economic conditions. The Company is subject to a number of risks similar to other clinical-stage biopharmaceutical companies, including, but not limited to, the need to obtain adequate additional funding, possible failure of current or future preclinical studies or clinical trials, its reliance on third parties to conduct its clinical trials, the need to obtain regulatory and marketing approvals and insurance coding for its product candidates, competitors developing new technological innovations, the need to successfully commercialize and gain market acceptance of the Company’s product candidates, protection of its proprietary technology, and the need to secure and maintain adequate manufacturing arrangements with third parties. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, income and expenses as well as the disclosure of contingent assets and liabilities, at the date of the financial statements during the reporting periods. In preparing these financial statements, management has made its best estimates and judgments of certain amounts included in the financial statements. Significant estimates and assumptions made in the accompanying 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 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 cease 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 Recently Adopted Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, “Financial Instruments—Credit Losses (Topic 326)” “ASU 2016-13”) . In August 2020, the FASB issued ASU 2020-06, “Debt – Debt with Conversion and Other Options (Subtopic 470-20)” and “Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40) (ASU 2020-06): Accounting for Convertible Instruments and Contracts in an Entity,” which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. The updated guidance is effective on a prospective basis for annual reporting periods beginning after December 15, 2023 and for interim periods within those periods. The Company early adopted this guidance as of January 1, 2022 and the pronouncement did not have any material impact on the Company’s financial position or results of operations.

Commitments and Contingencies	5. Commitments and Contingencies Legal Proceedings From time to time, the Company may become involved in legal proceedings arising in the ordinary course of business. The Company was not subject to any material legal proceedings during the six months ended June 30, 2024, and no material legal proceedings are subsequently outstanding or pending. Guarantees and Indemnification In the ordinary course of business, the Company enters into agreements that may include indemnification provisions. As permitted under Delaware law and in accordance with its bylaws, the Company indemnifies its officers and directors for certain events or occurrences while the officer or director is or was serving in such capacity. The Company is also party to indemnification agreements with its officers and directors. In some cases, the indemnification will continue after the termination of the agreement. The maximum potential amount of future payments that the Company could be required to make under these provisions is not determinable. The Company has never incurred material costs to defend lawsuits or settle claims related to these indemnification provisions. The Company is not currently aware of any indemnification claims. Accordingly, the Company has not recorded any liabilities for these indemnification rights and agreements as of June 30, 2024. Operating Leases The Company leases its headquarters in Los Altos, California under a month-to-month operating lease agreement. 20,000 19,000 41,000 37,000

Income Tax Disclosure [Abstract]
Income Taxes	7. Income Taxes The Company had no income tax expense for the three and six months ended June 30, 2024, and 2023. During the three months ended June 30, 2024, and 2023, the Company had a net operating loss (“NOL”) for each period that generated deferred tax assets for NOL carryforwards. Deferred income tax assets and liabilities are recognized for temporary differences between the financial statements and income tax carrying values using tax rates in effect for the years such differences are expected to reverse. Due to uncertainties surrounding our ability to generate future taxable income and consequently realize such deferred income tax assets, the Company has determined that it is more likely than not that these deferred tax assets will not be realized. Accordingly, the Company has established a full valuation allowance against its deferred tax assets as of June 30, 2024. The Company’s policy is to recognize any interest and penalties related to unrecognized tax benefits as a component of income tax expense. For the three and six months ended June 30, 2024, and 2023, the Company had no

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2024
Accounting Policies [Abstract]
Basis of Presentation and Unaudited Condensed Interim Financial Information	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, 2023, is derived from the Company’s audited financial statements. The results of operations for the three ended June 30, 2024, are not necessarily indicative of the results to be expected for the year ending December 31, 2023, 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 and as amended by Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”). Summary of Significant Accounting Policies There have been no material changes to the significant accounting policies during the six months ended June 30, 2024 from those previously disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 filed with the SEC on April 1, 2024 (the “2023 Annual Report”).
Risks and Uncertainties	Risks and Uncertainties The Company is subject to a number of risks associated with companies at a similar stage, including the risks associated with the development of products that must receive regulatory approval before market launch, dependence on key individuals, competition from larger and more established companies, volatility of the industry, ability to obtain adequate financing to support the Company’s business plan, the ability to attract and retain additional qualified personnel to manage the anticipated growth of the Company and general economic conditions. The Company is subject to a number of risks similar to other clinical-stage biopharmaceutical companies, including, but not limited to, the need to obtain adequate additional funding, possible failure of current or future preclinical studies or clinical trials, its reliance on third parties to conduct its clinical trials, the need to obtain regulatory and marketing approvals and insurance coding for its product candidates, competitors developing new technological innovations, the need to successfully commercialize and gain market acceptance of the Company’s product candidates, protection of its proprietary technology, and the need to secure and maintain adequate manufacturing arrangements with third parties.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, income and expenses as well as the disclosure of contingent assets and liabilities, at the date of the financial statements during the reporting periods. In preparing these financial statements, management has made its best estimates and judgments of certain amounts included in the financial statements. Significant estimates and assumptions made in the accompanying 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	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 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 cease 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	Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In June 2016, the FASB issued ASU 2016-13, “Financial Instruments—Credit Losses (Topic 326)” “ASU 2016-13”) . In August 2020, the FASB issued ASU 2020-06, “Debt – Debt with Conversion and Other Options (Subtopic 470-20)” and “Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40) (ASU 2020-06): Accounting for Convertible Instruments and Contracts in an Entity,” which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. The updated guidance is effective on a prospective basis for annual reporting periods beginning after December 15, 2023 and for interim periods within those periods. The Company early adopted this guidance as of January 1, 2022 and the pronouncement did not have any material impact on the Company’s financial position or results of operations.
