An Adaptive Clinical Platform Trial to Evaluate the Safety and Efficacy of COM701 as Monotherapy or Combination Therapy as Maintenance Therapy in Participants With Relapsed Platinum Sensitive Ovarian Cancer (PSOC)

What this Trial Is About

Researchers are evaluating the experimental antibody COM701 to see if it can delay the progression of relapsed platinum sensitive ovarian cancer, fallopian tube cancer, or primary peritoneal cancer. The trial aims to find out if COM701, given as maintenance treatment, can slow disease progression, delay the need for new anti-cancer treatments, and to understand its safety profile in participants who have had prior platinum-containing therapies. This trial is a randomized, double-blind, placebo-controlled study where participants have a 67% chance to receive COM701 and a 33% chance to receive a placebo. The treatment is given through intravenous infusion once every three weeks. The study includes multiple sub-studies, with initial focus on COM701 alone and later evaluation of COM701 combined with other anti-cancer drugs as maintenance therapy. Participants will visit the clinic every three weeks for treatment infusion and undergo various health checks including physical exams, vital signs, ECG, blood and urine tests, and pregnancy tests if applicable. Disease response is monitored through tumor imaging by CT or MRI scans and analysis of tumor tissue samples. The main outcome is progression-free survival over up to two years, with safety monitored during and up to 90 days after treatment. The study duration and follow-up depend on individual participant progress.
