VIO-01 is the next-generation DNA decoy generated from Valerio Therapeutics’ proprietary PlatON platform. An optimized product with modifications for increased half-life, plasma stability and tumor targeting, VIO-01 is a potent pan-DDR trapper capable of abrogating multiple DNA damage pathways including homologous recombination and non-homologous end joining. The pan trapping nature of VIO-01 allows for treatment of a wide range of potential solid tumor indications rather than restrictions to BRCA1/2 mutations or HRD positivity as with other DNA damage inhibitors.
The Clinical Review Committee (CRC) is composed of Valerio Therapeutics Medical and Safety teams as well as Principal Investigators convened to review all available and relevant safety information from the first cohort of 3 patients. No clinically significant adverse events or serious adverse events were reported and no MTD was declared, allowing the Clinical Review Committee to unanimously agree to escalate to the second dose cohort.
The VIO-01-101 Phase 1b portion of the trial aims to determine to recommended phase 2 dose and/or pharmacologically active dose in patients with selected solid tumors including, HRD+ Ovarian cancer, BRCA1/2 mutant Breast Cancer, HRR mutated prostate cancer, and solid tumors with HRR mutations. The dose escalation to clinically relevant exposures and safety expansion is expected to continue through 2024.
Dr. Shefali Agarwal, Chairwoman of the Board of Directors and CEO, stated:
"The result of this meeting represents one of the key milestones in the development of VIO-01 and the PlatON platform. This is an import step on our way to becoming a leader in the development of innovative drugs with unique mechanisms of action. We are pleased with the encouraging tolerability seen in this first cohort of patients and look forward to bringing this drug-candidate another step closer to patients. Most importantly, we’d like to thank our dedicated investigators and patients for their willingness to participate in this trial and are excited for our continued future work together."
