Rucaparib vs Placebo Maintenance Therapy in Metastatic and Recurrent Endometrial Cancer

A Phase II, Randomized, Double-Blind Study of the Use of Rucaparib vs. Placebo Maintenance Therapy in Metastatic and Recurrent Endometrial Cancer

This study seeks to determine the effectiveness of Rucaparib as maintenance therapy for metastatic and recurrent endometrial cancer, after 1-2 prior lines of therapy.

This is a phase II clinical trial, that administers a maintenance treatment after first line chemotherapy is complete. It is designed to have a 1:1 randomization technique. Half the participants who enter the study will receive the active ingredient, Rucaparib, while the other half will receive a placebo. Treatment will be until progression with follow up until death.
