Summary

This trial is testing whether olaparib alone or with bevacizumab is better than standard treatment for patients with advanced colorectal cancer who haven't gotten worse after initial therapy. Olaparib helps kill cancer cells by stopping them from repairing themselves, while bevacizumab cuts off the tumor's blood supply. The study aims to see if these new combinations can keep the cancer from progressing longer than current treatments.

Eligible Conditions

Trial Design

3Treatment groups
Experimental Treatment
Active Control
Group I: Olaparib + bevacizumabExperimental Treatment2 Interventions
Participants will receive olaparib (300 mg twice daily \[BID\] oral) + Bevacizumab (5 mg/kg intravenous \[IV\] once every 2 weeks \[Q2W\]) until progressive disease or end of study.
Group II: OlaparibExperimental Treatment1 Intervention
Participants will receive olaparib (300 mg BID) oral, until progressive disease or end of study.
Group III: Bevacizumab + chemotherapyActive Control4 Interventions
Participants will receive investigator's choice of either bevacizumab (7.5 mg/kg IV once every three weeks (Q3W)) + capecitabine (1000 mg/m\^2 BID for 14 days, then 7 days off, Q3W) or bevacizumab (5 mg/kg IV Q2W) + 5-FU (2400 mg/m2 IV over 46 to 48 hours Q2W; bolus 5-FU (400 mg/m2) can be added prior to infusional 5-FU, per local standards and at the investigator's discretion). Leucovorin or levoleucovorin 400 mg/m\^2 (leucovorin) or 200 mg/m\^2 (levoleucovorin) Q2W IV infusion may be added per investigator's discretion. Treatment will continue until progressive disease or end of study.
