Genelux Corporation Reports Third Quarter 2025 Financial Results and Provides General Business Updates

November 05, 2025 16:20 ET | Source: Genelux Corporation -- Lung cancer programs progressing with interim data updates expected in Q4 2025 -- -- Topline data from OnPrime Phase 3 ovarian cancer registrational trial expected in the second half of 2026 -- -- Cash, cash equivalents, short-term investments and restricted cash of $21.0 million as of September 30, 2025 -- WESTLAKE VILLAGE, Calif., Nov. 05, 2025 (GLOBE NEWSWIRE) -- Genelux Corporation (NASDAQ: GNLX), a late clinical-stage immuno-oncology company, today announced financial results for the third quarter of 2025 and provided general business updates. “In the third quarter, we continued to progress Olvi-Vec’s development across multiple solid tumor indications, positioning the program for meaningful clinical milestones and key catalysts in the coming year in indications that, together, represent a multi-billion-dollar market opportunity. Olvi-Vec’s differentiated mechanism of action is designed to directly kill cancer cells, stimulate a tumor-specific immune response, and alter the tumor microenvironment, with the potential to resensitize tumors to frontline platinum-based chemotherapy,” said Thomas Zindrick, President, CEO and Chairman of Genelux. “Enrollment in our Phase 3 ovarian cancer trial remains active across U.S. sites, and we are pleased to see strong engagement from investigators. Given the complexities inherent to running rigorous, randomized studies that can enable streamlined regulatory review, we now expect data in the second half of 2026. We look forward to sharing topline results from the Phase 3 ovarian cancer trial next year, and remain well-positioned to execute on our clinical and regulatory priorities.” “Looking ahead, we are also excited about our lung cancer studies, where Olvi-Vec is being delivered via systemic (intravenous) delivery, a physician-preferred route of administration that could support broader commercial opportunities across other solid tumors. We expect to share additional interim data from our systemic lung cancer programs in the fourth quarter of 2025, where ongoing studies aim to further validate our oncolytic immunotherapy platform. A positive signal in lung cancer could mark a pivotal inflection point for our pipeline and position the Company for the next phase of growth,” concluded Mr. Zindrick. Clinical Program Highlights Olvi-Vec in Platinum-Resistant/Refractory Ovarian Cancer: Genelux continues to advance Olvi-Vec toward potential registration in platinum-resistant/refractory ovarian cancer (PRROC). Intraperitoneal administration of Olvi-Vec offers an attractive approach for high and condensed dosing in PRROC, where patients need options that can deliver anti-tumor activity and effectively reverse platinum resistance: The ongoing OnPrime Phase 3 registrational trial (NCT05281471) of Olvi-Vec in platinum-resistant/refractory ovarian cancer is enrolling patients at sites across the United States, with topline data now anticipated in the second half of 2026.The OnPrime study is a multi-center, randomized open-label phase 3 study evaluating the safety and efficacy of Olvi-Vec followed by platinum-doublet chemotherapy and bevacizumab compared to the active comparator arm with physician's choice of chemotherapy and bevacizumab in women diagnosed with platinum-resistant/refractory ovarian cancer (includes fallopian tube cancer and primary peritoneal cancer). The Independent Data Monitoring Committee has regularly reviewed and recommended continuation of the trial without modifications.Based on a Type D meeting with the U.S. Food and Drug Administration, Genelux believes data from OnPrime could potentially support traditional regulatory approval if a clinically meaningful progression-free survival advantage is demonstrated without a decrement in overall survival. Olvi-Vec in Lung Cancer:Genelux is advancing two ongoing trials of systemically delivered Olvi-Vec in lung cancer. These trials are designed to demonstrate that Olvi-Vec’s oncolytic immunotherapy mechanism can extend beyond intraperitoneal delivery into a systemic setting across multiple solid tumor types and showcase Olvi-Vec’s potential to resensitize tumors to platinum-based chemotherapy: The Phase 2 study (NCT06463665) in recurrent non-small cell lung cancer (NSCLC) is assessing Olvi-Vec in combination with standard-of-care regimens, including platinum-based chemotherapy and an immune checkpoint inhibitor.The Phase 1b/2 study (OLVI-VEC-SCLC-202) in small-cell lung cancer (SCLC) is evaluating Olvi-Vec in combination with platinum and etoposide in patients with platinum-resistant or relapsed disease. We are continuing to enroll in the dose-escalation portion of these open-label lung cancer studies, which will support determination of a systemic dose for future trials. Further to SCLC data shared earlier this year, additional interim data from both trials are expected to be shared in the fourth quarter of 2025 and throughout 2026. Third Quarter 2025 Financial Results Cash, cash equivalents, short-term investments and restricted cash were $21.0 million as of September 30, 2025. The Company expects its existing cash, cash equivalents, short-term investments and restricted cash will provide runway into the third quarter of 2026. Research and development (R&D) expenses were $4.7 million and $4.1 million for the three months ended September 30, 2025 and 2024, respectively, an increase of $0.7 million. The increase was primarily driven by stock compensation and clinical and regulatory expenses relating to increased clinical trial costs associated with our Phase 3 On Prime registration trial. General and administrative (G&A) expenses were $3.5 million and $2.9 million for the three months ended September 30, 2025 and 2024, respectively, an increase of $0.6 million. The increase was primarily driven by stock compensation and salary and benefits, partially offset by a decrease in professional services. Net loss was $8.0 million for the third quarter of 2025 or a net loss per share of $0.21, as compared to a net loss of $6.5 million for the third quarter of 2024, or a net loss per share of $0.19. About Genelux Corporation Genelux is a late clinical-stage biopharmaceutical company focused on developing a pipeline of next-generation oncolytic immunotherapies for patients suffering from aggressive and/or difficult-to-treat solid tumor types. Olvi-Vec currently is being evaluated in two U.S.-based clinical trials: OnPrime/GOG-3076, a multi-center, randomized, open-label Phase 3 registrational trial evaluating the efficacy and safety of Olvi-Vec in combination platinum-doublet + bevacizumab compared with physician's choice of chemotherapy and bevacizumab in patients with platinum-resistant/refractory ovarian cancer; and, VIRO-25, a multi-center, randomized, open-label Phase 2 trial evaluating the efficacy and safety of Olvi-Vec & platinum-doublet + physician's choice of immune checkpoint inhibitor compared to docetaxel in non-small-cell lung cancer. Additionally, Olvi-Vec currently is being evaluated for dose selection in Olvi-Vec-SCLC-202, a China-based, multi-center, open label Phase 1b trial evaluating the efficacy and safety of Olvi-Vec & platinum-doublet in recurrent small-cell lung cancer. The core of Genelux's discovery and development efforts revolves around its proprietary CHOICE™ platform from which the Company has developed an extensive library of isolated and engineered oncolytic vaccinia virus immunotherapeutic product candidates, including Olvi-Vec.
