A Clinical Trial to Evaluate the Safety and Efficacy of COM701 in Relapsed Platinum Sensitive Ovarian Cancer

Recruiting now · Phase 1/Phase 2 · Has a placebo group

Conditions studied: Ovarian Cancer, Ovarian Cancer Recurrent

In brief

The goal of this clinical trial is to learn if the experimental antibody COM701 delays the progression of ovarian cancer in participants with Relapsed Platinum Sensitive Ovarian Cancer. It will also learn about the safety of COM701. The main questions the trial aims to answer are: * Does COM701, when used as a maintenance treatment, stop or slow the progression of ovarian cancer? * Does COM701 delay the time to needing a new anti-cancer treatment? * What side effects do participants have when taking COM701? Participants will: * Visit the clinic once every 3 weeks during which the study treatment will be administered intravenously * Undergo various tests and procedures to monitor general health throughout the trial including physical examinations, vital sign measurements (heart rate, blood pressure, breathing, and body temperature), weight measurements, electrocardiography (ECG), blood and urine tests and pregnancy tests if relevant. * Undergo various tests and procedures to assess disease response throughout the trial including tumor imaging by CT scans or MRI to assess the tumor, its location, and size, and the testing of a sample of tumor tissue (from a prior biopsy or a fresh biopsy if feasible, to evaluate tumor response to treatment and to measure levels of tumor markers,

You may not qualify if…

Has had 4 or more lines of cytotoxic chemotherapy in total
Is being treated with immunosuppressive doses of systemic medications, such as steroids within 2 weeks before study drug administration
Has had prior treatment with PD-1, PD-L1, anti-PVRIG, TIGIT or any other check point inhibitors
Presence of radiographic or biopsy proven liver metastases at the beginning or completion of current line of platinum-based chemotherapy.
