ARIEL4: A Study of Rucaparib Versus Chemotherapy BRCA Mutant Ovarian, Fallopian Tube, or Primary Peritoneal Cancer Patients

About the Study

ARIEL4 is a treatment study for women with relapsed, high-grade epithelial ovarian, fallopian tube, or primary peritoneal cancer who have a BRCA1 or BRCA2 mutation. ARIEL4 is designed to evaluate rucaparib against standard of care chemotherapy in women who have had at least two prior chemotherapy regimens. Visit the ARIEL4 Study page for more information. 

Type of Study

ARIEL4 is a randomized, 2-arm, open-label cross-over study. 

  • This is a randomized study, which means that participants will be placed into one of the two treatment groups by chance. Neither patients nor the research doctor will choose the group participants are placed in. This is a 2:1 randomized study. This means that patients will have a slightly greater chance of being placed in the treatment group than the standard treatment group.
  • The study has 2 arms. This means that patients in the study are placed in one of two different groups. One group will received the PARP inhibitor rucaparib and the other group will receive one of several standard chemotherapy treatment options chosen by their oncologist.
  • The study is open-label. All participating patients will know which group they have been assigned to.
  • The study allows crossover. this means that patients who progress on the standard treatment arm will be given the opportunity to crossover into the rucaparib arm if they choose. 

What the Study Entails

  • Patients chosen to be on the rucaparib arm will receive oral rucaparib twice daily.
  • Patients chosen to be on the chemotherapy arm will receive one of several standard of care chemotherapy options as chosen by their doctor. 

Patient who qualify for the ARIEL4 trial and enroll, receive the following as part of the study: standard-of-care and study related clinical exams, blood tests, imaging scans of your cancer, lab test results including BRCA and the other biomarker tests, the study medication (rucaparib or chemotherapy) and other assessments. Patients who were treated with chemotherapy on the main study and then experience a worsening of their ovarian cancer may be eligible to receive rucaparib after they discontinue chemotherapy.
