Olaparib Treatment in BRCA Mutated Ovarian Cancer Patients After Complete or Partial Response to Platinum Chemotherapy

• Status: Active, not recruiting
• Trial end date: 2022-02-25
• Target enrollment: 0
• Participant gender: Female

Summary

A Phase III, randomised, double-blind, placebo-controlled, multi-centre study to assess the efficacy of olaparib maintenance monotherapy in relapsed high grade serous ovarian cancer (HGSOC) patients (including patients with primary peritoneal and / or fallopian tube cancer) or high grade endometrioid cancer with BRCA mutations (documented mutation in BRCA1 or BRCA2 that is predicted to be deleterious or suspected deleterious (known or predicted to be detrimental/lead to loss of function)) who have responded following platinum based chemotherapy.

• Phase: Phase 3
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: AstraZeneca
• Collaborators: European Network of Gynaecological Oncological Trial Groups (ENGOT); European Network of Gynaecological Oncology Trial Groups (ENGOT); Merck Sharp & Dohme Corp.; Myriad Genetic Laboratories, Inc.
• Treatments: Olaparib

Criteria

Inclusion Criteria:

• Patients must be ≥ 18 years of age.

• Female patients with histologically diagnosed relapsed high grade serous ovarian cancer (including primary peritoneal and / or fallopian tube cancer) or high grade endometrioid cancer.

• Documented mutation in BRCA1 or BRCA2 that is predicted to be deleterious or suspected deleterious (known or predicted to be detrimental/lead to loss of function).

• Patients who have received at least 2 previous lines of platinum containing therapy prior to randomisation

For the penultimate chemotherapy course prior to enrolment on the study:

• Patient defined as platinum sensitive after this treatment; defined as disease progression greater than 6 months after completion of their last dose of platinum chemotherapy

For the last chemotherapy course immediately prior to randomisation on the study:

• Patients must be, in the opinion of the investigator, in response (partial or complete radiological response), or may have no evidence of disease (if optimal cytoreductive surgery was conducted prior to chemotherapy), and no evidence of a rising CA-125, following completion of this chemotherapy course

• Patient must have received a platinum based chemotherapy regimen (e.g. carboplatin or cisplatin) and have received at least 4 cycles of treatment

• Patients must be randomized within 8 weeks of their last dose of chemotherapy

• Maintenance treatment is allowed at the end of the penultimate platinum regimen, including bevacizumab

Exclusion Criteria:

• Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site).

• BRCA 1 and/or BRCA2 mutations that are considered to be non detrimental (e.g., "Variants of uncertain clinical significance" or "Variant of unknown significance" or "Variant, favor polymorphism" or "benign polymorphism" etc.)

• Patients who have had drainage of their ascites during the final 2 cycles of their last chemotherapy regimen prior to enrolment on the study.
