Trial ID # NCT01650376
Phase 1b
Drug Class DNA Damage Repair Pathway Inhibitors: PARP
Drug Name Olaparib

Therapy Setting


Study Design

Open-Label, Non-randomized


ORR, PFS, OS, RP2D, evaluated per RECIST


RP2D: 150 mg olaparib (tablet) BID, metronomic carboPt AUC2 and paclitaxel 60 mg/m2

ORR: 54% (13CR, 16PR, n=54)

Exploratory analysis, BRCA status:
BRCA MUT (n=23) vs BRCA WT (n=24):
PFS: 12.1 vs 4.8 months (p=0.0001)
OS: 24.1 vs 10.4 months (p=0.02)

Clinically Significant Adverse Events

Serious AE:
Grade 3-4 AE: 78%


Olaparib can be safely administered with metronomic carboplatin and paclitaxel in recurrent ovarian cancer, but BRCA MUT patients experience most benefit
