This study examines Olaparib combined with either Cediranib or Ceralasertib (AZD6738) in patients with advanced or metastatic germline BRCA-mutated breast cancer. Women over 18 with HER2-negative, BRCA germline-positive breast cancer who have previously been treated with a PARP inhibitor can take part. It is being conducted in Phase 2 and is currently recruiting participants.
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.

Estrogen receptor positive (ER+) patients must have progressed on a prior endocrine therapy or are considered inappropriate for any FDA approved endocrine therapies for ER+ breast cancer.
3. Eligible patients must agree to a mandatory fresh biopsy (excluding bone) at screening. In addition, if available, an archival tissue sample will also be collected at screening.
