1. Business and Principal Activities | 1. Business and Principal Activities Description of Business RenovoRx, Inc. (the “Company”) 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 therapies for the local treatment of solid tumors and conducting a Phase III pancreatic cancer clinical trial for its lead product candidate RenovoGem™. The Company’s therapy platform, RenovoRx Trans-Arterial Micro-Perfusion, or RenovoTAMP® utilizes approved chemotherapeutics with validated mechanisms of action and well-established safety and side effect profiles, with the goal of increasing their efficacy, improving their safety, and widening their therapeutic window. Initial Public Offering On August 25, 2021, the Company’s Registration Statement on Form S-1 (File No. 333-258071) relating to its initial public offering (“IPO”) was declared effective and its shares of common stock began trading on the Nasdaq Capital Market on August 26, 2021. In connection with the IPO, the Company issued and sold an aggregate of 1,850,000 units at a price of $9.00 per unit. Each unit consisted of (a) one share of common stock and (b) one warrant to purchase one share of common stock at an exercise price equal to $10.80 per share, which is exercisable for a period of five years after the issuance date. The underwriters exercised their over-allotment option to purchase 277,500 common stock warrants on August 30, 2021. In connection with the IPO, the underwriters were issued a five-year warrant, exercisable on or after February 25, 2022, to purchase up to 198,875 shares of the Company’s common stock at an exercise price of $10.80. The Company received aggregate gross proceeds of $16.7 million from the IPO, paid underwriting discounts and commissions of $1.3 million and incurred other expenses of $0.8 million, resulting in net offering proceeds of $14.6 million. Immediately prior to the closing of the IPO, all shares of convertible preferred stock then outstanding were converted into 3,535,469 shares of common stock after giving effect to the reverse stock split. In addition, all of the outstanding 2020 and 2021 Convertible Notes, representing principal and accrued but unpaid interest of $5.3 million, converted at a 20% and 12.5% discount to the IPO price, respectively, into an aggregate of 708,820 units. Each unit consisted of (a) one share of common stock and (b) one five-year warrant to purchase one share of common stock at an exercise price equal to $10.80 per share. Reverse Stock Split On August 5, 2021, the Company effected a 1-for-5 reverse stock split of its issued and outstanding preferred stock and common stock. The number of authorized shares and the par values of the common stock and convertible preferred stock were not adjusted as a result of the reverse stock split. Adjustments corresponding to the reverse stock split were made to the ratio at which the Company’s convertible preferred stock converted into the Company’s common stock. Accordingly, all share and per share amounts related to the common stock, stock options, warrants and restricted stock awards for all periods presented in the accompanying financial statements and notes thereto have been retroactively adjusted. Liquidity and Capital Resources From the Company’s inception through December 31, 2022, it has raised an aggregate of $35.0 million from private placements of convertible preferred stock, convertible debt securities, the issuance of securities in the IPO, and the exercise of warrants and common stock options. As of December 31, 2022, the Company had cash, cash equivalents and short-term marketable securities of $6.4 million. The Company has incurred significant losses and negative cash flows from operations since its inception. For the year ended December 31, 2022, the Company reported a net loss of $9.9 million and an accumulated deficit of $31.2 million and does not expect to generate positive cash flows from operations in the foreseeable future. The Company expects to incur significant and increasing losses until regulatory approval is granted for its first product candidate, RenovoGem™. Regulatory approval is not guaranteed and may never be obtained. The Company believes it will be able to raise additional 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. The Company has filed an omnibus shelf registration statement on Form S-3 that provides for the aggregate offerings of up to $50.0 million of the Company’s securities subject to various limitations, including limited sales in any twelve-month period while the Company is subject to the “baby-shelf” rules. The Company has also filed a registration statement on Form S-1 to register the cash exercise of the Company’s outstanding IPO, underwriter and private warrants. Cash exercise of the outstanding warrants is only expected to occur when the trading price of the Company’s common stock is in excess of the $10.80 per share exercise price of the outstanding warrants. 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 the effects of the ongoing novel coronavirus (“COVID-19”) pandemic, cash requirements for the upcoming year, funding capacity, net working capital, total stockholders’ equity and future access to capital. Based upon this review and the Company’s current financial condition, the Company has concluded that substantial doubt exists as to the Company’s ability to continue as a going concern.
