EMBRACA: This phase III trial is comparing the safety of an oral drug (talazoparib), with standard treatment, in patients with locally advanced or metastatic breast cancerA Phase 3, Open-Label, Randomized, Parallel, Two-Arm, Multi Center Study of Talazoparib (BMN 673) versus Physician's Choice in Germline BRCA Mutation Patients with Locally Advanced and/or Metastatic Breast Cancer, Who Have Received Prior Chemotherapy Regimens for Metastatic Disease

Exclusion

• First-line locally advanced and/or metastatic breast cancer with no prior adjuvant chemotherapy unless the Investigator determines that one of the 4 cytotoxic chemotherapy agents in the control arm would otherwise be offered to the subject
• Prior treatment with a PARP inhibitor (not including iniparib)
• Not a candidate for treatment with at least 1 of the treatments of protocol-specific physician's choice (ie, capecitabine, eribulin, gemcitabine, vinorelbine)
• Subjects who had objective disease progression while receiving platinum chemotherapy administered for locally advanced or metastatic disease; subjects who received low-dose platinum therapy administered in combination with radiation therapy are not excluded
• Subjects who have received platinum in the adjuvant or neoadjuvant setting are eligible; however, subjects may not have relapsed within 6 months of the last dose of prior platinum therapy
• Cytotoxic chemotherapy within 14 days before randomization
• Radiation or anti-hormonal therapy or other targeted anticancer therapy within 14 days before randomization
• HER2 positive breast cancer
• Active inflammatory breast cancer

• CNS metastases

  • Exception: Adequately treated brain metastases documented by baseline CT or MRI scan that has not progressed since previous scans and that does not require corticosteroids (except prednisone ≤ 5 mg/day or equivalent) for management of CNS symptoms. A repeat CT or MRI following the identification of CNS metastases (obtained at least 2 weeks after definitive therapy) must document adequately treated brain metastases.
  • Subjects with leptomeningeal carcinomatosis are not permitted

• Prior malignancy except for any of the following:

  • Prior BRCA-associated cancer as long as there is no current evidence of the cancer
  • Carcinoma in situ or non-melanoma skin cancer
  • A cancer diagnosed and definitively treated ≥ 5 years before randomization with no subsequent evidence of recurrence
• Known to be human immunodeficiency virus positive
• Known active hepatitis C virus, or known active hepatitis B virus
• Known hypersensitivity to any of the components of talazoparib
