Eligibility Criteria

Inclusion Criteria

• Adult patients over 18 years
• PALB2 germline heterozygous mutation carrier, wild type BRCA1&2 (breast cancer 1&2) affected with metastatic breast cancer in first metastatic treatment line or beyond
• Histologically or cytologically confirmed breast cancer with evidence of metastatic disease.
• Triple Negative breast cancer; Patients affected with triple negative cancers should have received anthracyclines and taxanes in neo/adjuvant therapy.
• Or patients with Hormonal receptor positive (HR+)/ Human epidermal growth factor receptor 2 negative (HER2-) breast cancer, with treatment failure after a second line of therapy; Estrogen Receptor/ProgesteroneReceptor breast cancer positive patients must have received and progressed on currently recommended therapies in this indication (endocrine therapy, CDK4/6 inhibitors (adjuvant or metastatic)), or have a disease form that the treating physician believes to be inappropriate for recommended therapies in this indication.
• Prior therapy with an anthracycline and a taxane in an adjuvant setting.
• Prior platinum allowed as long as no breast cancer progression occurred on treatment or if given in adjuvant/neoadjuvant setting, at least 12 months elapsed from last dose to study entry.
