Efficacy and Safety of Olaparib (MK-7339) With or Without Bevacizumab Compared to Bevacizumab With a Fluoropyrimidine in Unresectable or Metastatic Colorectal Cancer (CRC) (MK-7339-003/LYNK-003)

Summary

This is an efficacy and safety study of olaparib alone or in combination with bevacizumab being compared to bevacizumab with a fluoropyrimidine in participants with unresectable or metastatic colorectal cancer who have not progressed following first-line induction. The primary hypotheses are: Olaparib + Bevacizumab is superior to a fluoropyrimidine + Bevacizumab with respect to progression-free survival (PFS) using Response Evaluation Criteria In Solid Tumors version 1.1 (RECIST 1.1) as assessed by blinded independent central review (BICR); Olaparib is superior to a fluoropyrimidine + Bevacizumab with respect to PFS using RECIST 1.1 as assessed by BICR. As of amendment 5 study enrollment is being discontinued and study participants randomized to one of the two experimental arms (olaparib plus bevacizumab or olaparib monotherapy) must discontinue study intervention. Participants who are still on study treatment will no longer have tumor response assessments by BICR.
