If approved, niraparib in combination with abiraterone acetate (AA), will be the first dual action tablet (DAT) available in the European Union for first-line treatment of adult patients with metastatic castration-resistant prostate cancer (mCRPC) with BRCA1/2 mutations, when given with prednisone (P) or prednisolone.[i] The positive CHMP opinion is based on results from the Phase 3 MAGNITUDE study where the addition of niraparib to AA plus P significantly improved radiographic progression-free survival (rPFS) compared to standard of care in untreated mCRPC patients with BRCA1/2 mutations.[ii]
