Patients Enrolled

565, median 1 prior therapy

Therapy Setting


Study Design

Open-Label, Randomized


ORR, PFS, OS, evaluated per RECIST


Ola+Ced (n=189) vs Ola (n=189) vs Treatment of Physician's Choice (TPC) (CarboPt+Gem (27%)/PLD (48%)/Pac (25%)) (n=187):

ORR: 69.4 vs 52.4 vs 71.3%
PFS: 10.4 vs 8.2 vs 10.3 months, HR: 0.86 (0.66-1.11, p=0.077); HR: 1.20 (0.93-1.54)
OS: 30.5 vs 29.2 vs 31.3 months

Exploratory analysis, gBRCA status:
gBRCA MUT: ORR: 89 vs 90 vs 71%; PFS: 18.0 vs 12.7 vs 10.5 months, HR: 0.55 (0.32-0.94); HR: 0.63 (0.37-1.07)
gBRCA WT: ORR: 64 vs 40 vs 72%; PFS: 8.9 vs 6.6 vs 9.7 months, HR: 0.97 (0.73-1.30); HR: 1.41 (1.07-1.81)

Clinically Significant Adverse Events

Ola+Ced vs Ola vs TPC:
Serious AE:
Grade 3-4 AE: neutropenia (3.8 vs 1.6 vs 31.8%), anemia (5.5 vs.15.0 vs 13.8%), thrombocytopenia (1.6 vs 1.0 vs 15.0%), leukopenia (1.1 vs 1.1 vs 14.4%), fatigue (17.5 vs 7.0 vs 1.8%), diarrhea (13.7 vs 1.0 vs 1.8%), hypertension (31.7 vs 5.3 vs 1.8%)


Cediranib+olaparib has similar activity to standard of care in relapsed platinum sensitive ovarian cancer but does not improve PFS
