A Phase 2 interventional study of OLAPARIB in Relapsed Ovarian Cancer, BRCA Mutation, Platinum Sensitivity, sponsored by AstraZeneca. Completed at 47 sites in 2 countries. Open to female participants aged 18 Years to 130 Years. Per ClinicalTrials.gov, last updated 2022-04-13.
Sponsored by AstraZeneca · Phase 2, Interventional, and Treatment
This is a non-randomized, open-label study to assess olaparib tablets as a treatment for subjects with different homologous recombination deficiency (HRD) tumor status and with platinum-sensitive, relapsed, high-grade serous or high-grade endometrioid ovarian cancer. Subjects should have received at least 1 prior line of platinum-based chemotherapy.
This is a Phase II, open-label, non-randomized, multi-center study assessing the efficacy and safety of olaparib tablets 300 mg (two 150 mg tablets) given orally twice daily (bid) in subjects with platinum-sensitive or partially platinum-sensitive, relapsed, high-grade serous or high-grade endometrioid epithelial ovarian, fallopian tube, or primary peritoneal cancer, who have received at least 1 prior line of platinum-based chemotherapy.
The study will assess the effectiveness of olaparib tablets as measured by the objective response rate (ORR) as determined by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1, in subjects with germline BRCA mutations (gBRCAm), somatic BRCA mutations (sBRCAm), or potential aberrations in homologous recombination deficiency (HRD) as determined by myChoice® HRD, as well as in subjects without identifiable HRD. This study will utilize Myriad BRACAnalysis CDx® for germline BRCA analysis and a tumor test (myChoice® HRD) for tumor BRCA analysis and HRD status. Four cohorts will be identified based upon the genetic testing described above:

Collected over Adverse events (AEs), serious AEs, AEs of special interest (AESIs), and AEs leading to discontinuation were collected from signature of informed consent for study participation. Treatment emerging AEs were reported from date of first dose of study treatment and continued throughout the active treatment period and the follow-up period 30 days after the last dose of olaparib. After the primary analysis data cut-off till study completion, only deaths, SAEs, AESIs and DAEs were collected/reported.. Non-serious events are listed at a 0% frequency threshold.
