A Randomized Phase II/III Study of the Combination of Cediranib and Olaparib Compared to Cediranib or Olaparib Alone, or Standard of Care Chemotherapy in Women With Recurrent Platinum-Resistant or -Refractory Ovarian, Fallopian Tube, or Primary Peritoneal Cancer (COCOS)

In Brief

A Phase 3 clinical trial evaluating Cediranib, Cediranib Maleate, and 8 other interventions for Fallopian Tube Clear Cell Adenocarcinoma and 14 related conditions. Active but no longer recruiting, targeting 582 participants across 398 sites in 5 countries.

Detailed Summary

This randomized phase II/III trial studies how well cediranib maleate and olaparib work when given together or separately, and compares them to standard chemotherapy in treating patients with ovarian, fallopian tube, or primary peritoneal cancer that has returned (recurrent) after receiving chemotherapy with drugs that contain platinum (platinum-resistant) or continued to grow while being treated with platinum-based chemotherapy drugs (platinum-refractory). Cediranib maleate and olaparib may stop the growth of tumor cells by blocking enzymes needed for cell growth. Chemotherapy drugs work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving cediranib maleate and olaparib together may cause more damage to cancer cells when compared to either drug alone or standard chemotherapy.
