Trial ID # | NCT02855944; ARIEL4 |
Phase | III |
Drug Class | DNA Damage Repair Pathway Inhibitors: PARP |
Drug Name | Rucaparib |
Alternate Drug Names | AG-014699, PF 01367338, CO-338, Rubraca |
Drugs in Trial | Carboplatin, Cisplatin, Paclitaxel, Rucaparib, Gemcitabine |
Eligible Participant | Recurrent BRCA MUT ovarian cancer |
Patients Enrolled | 349; median 2 prior therapies; 21% Pt-S. 28% Part-Pt-S, 51% Pt-R; 6.6% w/ BRCA reversion mutation |
Therapy Setting | Recurrence |
Study Design | Open-Label, Randomized |
Endpoints | ORR, DoR, PFS, OS, evaluated per RECIST |
Biomarkers | BRCA status |
Efficacy | Ruc (n=205) vs Treatment of Physician's Choice (TPC) (n=105) (Monotherapy platinum (cisplatin or carboplatin) or platinum-based doublet chemotherapy (carboplatin/paclitaxel, carboplatin/gemcitabine, or cisplatin/gemcitabine or single agent paclitaxel): ORR: 40.3 vs 32.3%, p=0.13 Exploratory analysis: w/ BRCA reversion mutation, Pt-status |
Clinically Significant Adverse Events | Ruc vs TPC: |
Conclusion | Recurrent BRCA MUT patients, including those who are platinum sensitive or platinum resistant, receive benefit with rucaparib treatment when compared to chemotherapy; the presence of a BRCA reversion mutation predicts for primary resistance to rucaparib |
