Platinum-sensitive Recurrent BRCA Wild Type Ovarian Cancer | Drug: Olaparib-Pembrolizumab-Bevacizumab | Phase 2 |
'This is a Phase II, open-label, non-randomized, multi-center study assessing the efficacy and safety of Olaparib maintenance with Bevacizumab and Pembrolizumab in subjects with platinum-sensitive who have received prior of platinum-based chemotherapy. The study will assess the effectiveness of progression-free survival(6 months PFS rate) as determined by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. The subject will be treated to until disease progression as below:
- Maintenance : Olaparib 300mg (twice daily [BID])
- Pembrolizumab 200mg every 3 weeks (Q3W) from 2nd infusion for up to 35 infusions
- Bevacizumab 15mg/kg or 7.5mg/kg every 3 weeks (Q3W)
Study Type : | Interventional (Clinical Trial) |
