Summary:

      This is an open-label study to assess the safety, tolerability and efficacy of olaparib in
      combination with carboplatin. There are two parts in this study: Part A, a dose escalation in
      patients with advanced Human Epidermal Growth Factor 2 (HER-2) negative breast cancer and
      Part B, a dose expansion in the neoadjuvant treatment of HER-2 negative breast cancer
      patients with germline Breast Cancer Susceptibility Gene (BRCA)1/2 mutations.

             suspected deleterious

          -  Eligible for neo-adjuvant chemotherapy, but have not yet received neoadjuvant
             chemotherapy for breast cancer (chemo-naive) Exclusion criteria

          -  Exposure to an investigational product within 30 days or 5 half-lives (whichever is
