Rucaparib vs Placebo Maintenance Therapy in Metastatic and Recurrent Endometrial Cancer

Participants allocated to the active ingredient arm will receive Rucaparib twice daily, 600mg, to be take by mouth. Patients will take the medication continuously over a 28 day cycle, until disease progression or other indication of discontinuation. Medication should be taken around the same time every day, with 8 or more ounces of water.

Patients will take the medication continuously over a 28 day cycle, until disease progression or other indication of discontinuation. Tablet should be taken around the same time every day, with 8 or more ounces of water.
