Introduction

• Maintenance therapy for patients with recurrent ovarian cancer is intended to extend PFS without compromising postprogressionsurvival

• In the phase 3 ARIEL3 study (CO-338-014; NCT01968213), rucaparib maintenance treatment significantly improved PFS vs placebo in all predefined patient cohorts1

oGreatest effects were seen in carcinomas deficient in HRR (eg, a mutation in BRCA or other HRR pathway gene, or high genomic LOH)1

• Here, we analyzed postprogression outcomes to evaluate the durability of the clinical benefit of rucaparib maintenance treatment following disease progression in the subgroup of patients with tumors associated with a mutation in a prespecified, non-BRCA HRR gene

HRR, homologous recombination repair; LOH, loss of heterozygosity; PFS, progression-free survival.1. Coleman et al. Lancet. 2017;390:1949─1961.

Initial Results: PFS and Safety from ARIEL3 in Patients With Carcinomas Associated With aNon-BRCA HRR Gene Mutation

• The safety profile of rucaparib in patients with a carcinoma associated with a non-BRCAHRR gene mutation was consistent with the overall safety populationo In the non-BRCA HRR gene mutation subgroup vs the overall population, incidence of grade ≥3 AEs

and AEs leading to dose reduction and/or treatment interruption of rucaparib were 55.6% vs 59.7% and 66.7% vs 71.8%, respectively

Conclusions

• Although the number of patients in this subgroup was small, rucaparib improved the clinically meaningful postprogression endpoints TFST, CFI, PFS2, and TSST vs placebo in patients with platinum-sensitive, recurrent ovarian cancer harboring a non-BRCAHRR gene mutation

oPrior rucaparib treatment did not adversely impact the possibility for patients in this subgroup to benefit from subsequent therapy

• Mutations in a subset of HRR genes, such as RAD51C/D, may confer greater sensitivity to PARP inhibitor treatment

CFI, time from the last dose of prior chemotherapy to initiation of first subsequent anticancer therapy; HRR, homologous recombination repair; PARP, poly(ADP-ribose) polymerase; PFS2, time from randomization to disease progression on subsequent line of therapy or death; TFST, time from randomization to start of first subsequent therapy; TSST, time from randomization to start of second subsequent therapy.
