Summary

The purpose of this study is to determine which patients with ovarian, fallopian tube, and primary peritoneal cancer will best respond to treatment with rucaparib.

Detailed description

Rucaparib is an orally available, small molecule inhibitor of poly-adenosine diphosphate \[ADP\] ribose polymerase (PARP) being developed for treatment of ovarian cancer associated with homologous recombination (HR) DNA repair deficiency (HRD). The safety and efficacy of rucaparib has been evaluated in several Phase 1 and Phase 2 studies. An oral formulation is the focus of current development efforts. Rucaparib is currently being investigated as monotherapy in patients with cancer associated with breast cancer susceptibility gene 1 (BRCA1) or BRCA2 mutations. Clinical data with PARP inhibitors indicate there is an ovarian cancer patient population beyond just those with germline BRCA (gBRCA) mutations that may benefit from treatment with a PARP inhibitor. This study will define a molecular signature of HRD in ovarian cancer that correlates with response to rucaparib and enables selection of appropriate ovarian cancer patients for treatment with rucaparib. The HRD signature will be based on an association between the extent of genomic scarring (a downstream consequence of HRD) in a patient's tumor and observed clinical benefit from rucaparib treatment. Genomic scarring can be assessed by quantifying the extent of loss of heterozygosity across the tumor genome (tumor genomic LOH). One of the main advantages of detecting tumor genomic LOH is that it can identify HRD tumors regardless of the underlying mechanisms, which include both known (i.e., BRCA mutations) and unknown genetic and other mechanisms. Once determined, this signature will be prospectively applied to ARIEL2 PART 2 and ARIEL3. This Phase 2 study (ARIEL2) will also compare archival versus recently collected tumor tissue in order to validate the use of archival tumor tissue for assessment of HRD status in ARIEL3. This study will include 2 parts: PART 1 (completed enrollment): Evaluation of HRD status and rucaparib efficacy in patients who received ≥1 prior platinum-based regimen and had platinum-sensitive disease PART 2 (completed enrollment): Evaluation of HRD status and rucaparib efficacy in patients who received at least 3 prior chemotherapy regimens
