Genelux Corporation is a clinical-stage biopharmaceutical company focused on pioneering advanced oncolytic viral immunotherapies for patients confronting aggressive and/or hard-to-treat solid tumor malignancies. Its leading experimental drug, Olvi-Vec, is a proprietary, engineered vaccinia virus strain being developed to address ovarian cancer and non-small cell lung cancer. The company is also advancing V2ACT Immunotherapy for pancreatic cancer, alongside V-VET1 for the treatment of both hematologic and solid cancers.

Genelux Announces Publication of a Deep and Durable Response in a Platinum-relapsed Small Cell Lung Cancer Patient Following Systemically Delivered Olvi-Vec-Primed Immunochemotherapy
Genelux published a peer-reviewed case report in Frontiers in Oncology showing a platinum-relapsed small cell lung cancer patient achieved 16.7 months progression-free survival after a single intravenous course of Olvi-Vec followed by platinum/etoposide rechallenge, exceeding the 14.3-month PFS from her first-line platinum therapy.
The patient's target lesions shrank 84.6%, and tumor reduction at four cycles of rechallenge was deeper than during first-line treatment (-78.9% vs -67.8%), supporting the hypothesis that Olvi-Vec remodels the tumor microenvironment and re-sensitizes tumors to platinum chemotherapy.
The case comes from the Phase 1b dose-escalation portion of the OLVI-VEC-202-SCLC trial (NCT07136285), co-sponsored with and conducted in China by licensing partner Newsoara HYK Biopharmaceuticals; enrollment is ongoing, with dose-finding updates from this trial and the Phase 2 VIRO-25 NSCLC trial expected in 2026.
Management cautions the single-patient result does not establish safety or efficacy; Genelux's pivotal asset test remains the Phase 3 OnPrime/GOG-3076 ovarian cancer trial underway in the U.S.
