Testing the Use of the Combination of Selumetinib and Olaparib or Selumetinib Alone Targeted Treatment for RAS Pathway Mutant Recurrent or Persistent Ovarian and Endometrial Cancers, A ComboMATCH Treatment Trial

Study Summary

This phase II ComboMATCH treatment trial compares selumetinib plus olaparib to selumetinib alone in women with endometrial or ovarian (fallopian tube and primary peritoneal) cancer that has come back (recurrent) or that remains despite treatment (persistent) and harbors a mutation in the RAS pathway. Selumetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Olaparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep tumor cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. The addition of olaparib to selumetinib could increase the percentage of tumors that shrink as well as lengthen the time that the tumors remain stable (without progression) as compared to selumetinib alone.

Primary Outcome

Disease progression will be defined using Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1 criteria, as determined by the treating physician. The primary analyses will be based on logrank tests stratified by the stratification factors as recorded at randomization. All enrolled patients will be included, regardless of compliance with their assigned study regimen. Patients will be grouped by their randomized treatment for intention-to-treat analyses.
