Brief summary

PFS based on BIRC assessment using RECIST 1.1 criteria

Detailed description

OS, Safety: Incidence, type and severity of adverse events per CTCAE v4.03 criteria including changes in laboratory values, vital signs, hepatic, renal and cardiac assessments. Tolerability: dose interruptions, reductions, dose intensity and duration of exposure for all drug components., Time to definitive deterioration of the ECOG performance status from baseline, Overall Response Rate (ORR) with confirmed response, Clinical Benefit Rate (CBR) with confirmed response, Duration Of Response (DOR) with confirmed response and Time To Response (TTR) (based on BIRC assessment using RECIST 1.1 criteria), Summary of statistics of PK parameters (including but not limited to AUCtau, AUClast, Cmax, Tmax) of alpelisib and olaparib (full PK subset only), Summary of statistics of plasma alpelisib and olaparib concentrations by time point., Change from baseline in Function Assessment of Cancer Therapy-Ovarian Trial Outcome Index (FACT-O)
