A Phase 1/2 Study of VIO-01 in Participants With Recurrent Solid Tumors

The goal of this phase 1/2 clinical trial is to investigate the safety of an investigational drug called VIO-01 when taken by people who have different types of solid tumor cancers. There are two parts to this trial, part 1 and part 2. Part 1 of the trial aims to answer these questions: * The safety and tolerability of VIO-01 when it is given alone or in combination with other anti-cancer therapies. * The highest dose that people can take without having unacceptable side effects * How well your body tolerates the drug alone or in combination, how they are absorbed, and the effects they have on your disease. Part 2 of the trial will further test VIO-01's effect in participants with advanced HRRm or HRD+ solid tumors and HRRm/HRD+ recurrent ovarian cancer. Participants will follow a schedule of visits to the study site to have assessments done related to their health condition and to receive the trial treatment.

This is a phase 1/2 open-label, multicenter, basket study to determine the safety, anti-tumor activity, tolerability, and PK/PD of VIO-01 alone or in combination with other anti-cancer therapies in select participants with advanced HRRm or HRD+ solid tumors (i.e. BRCA1/2 mutated breast cancer, HRR mutated prostate cancer) or HRRm/HRD+/HRP (phase 1 only) recurrent ovarian cancer.
