A study looking at rucaparib for ovarian cancer that has come back (ARIEL2)

This study looked at rucaparib for ovarian cancer that had gone away or got smaller after platinum chemotherapy.

It had 2 parts. Part 1 was for people whose cancer had come back 6 months after their last . Part 2 was for people whose cancer had come back and who had 3 to 4 different courses of chemotherapy.

The study was for people who had:

• ovarian cancer

• fallopian tube cancer

• primary peritoneal cancer

Also, they had a serous type cancer that was high grade. High grade means that the cancer is more likely to grow quickly.

These cancers are all treated in the same way. So, when we use the term ovarian cancer in this summary, we are referring to all 3.

There were 2 parts to this study. This summary includes results for part 1. We hope to add results for part 2 when they become available.
