Abstract

Background

Rucaparib has demonstrated clinical activity in BRCAmut HGOC in two phase 2 studies. Data from these studies were pooled to examine the clinical activity and safety of rucaparib in BRCAmut pts with HGOC who have received ≥2 prior chemotherapy (chemo) regimens.

Methods

Pts (n = 106) with BRCAmut relapsed, HGOC who received ≥2 prior chemo regimens and were enrolled in Study 10 part 2a (n = 42) or ARIEL2 part 1 or 2 (n = 64) by 1 Oct 2015 were included in the pooled efficacy analysis. The pooled safety dataset (n = 144) included 38 additional pts with

Results

Median age was 59 years; median number of prior chemo regimens was 3. Median duration of treatment was 6.9 months. The investigator-assessed confirmed objective response rate (RECIST v1.1) was 54% in pts with ≥2 prior chemo regimens. The median duration of investigator-assessed confirmed response was 9.2 months (95% confidence interval: 6.6-11.7). Common treatment-emergent adverse events included asthenia/fatigue (78%; grade ≥3: 15%), nausea (76%; grade ≥3: 4%), anemia (51%; grade ≥3: 27%), vomiting (50%; grade ≥3: 6%), and transient increased ALT/AST (47%; grade ≥3: 13%). Five pts died as a result of disease progression.

Conclusions

Rucaparib has clinical activity and an acceptable safety profile in pts with BRCAmut HGOC who received ≥2 prior lines of chemo. The efficacy of rucaparib will be compared to standard chemo in a phase 3 study (ARIEL4).
