Key Inclusion Criteria:

• Age ≥ 18 years
• Relapsed/metastatic solid tumors treated with prior adequate standard of care therapy for tumor type and stage of disease or where in the opinion of the Investigator, a clinical trial is the best option for the next treatment based on response and/or tolerability to prior therapy.

• Eastern Cooperative Oncology Group (ECOG) Performance Status: 0-1
• Life expectancy ≥ 12 weeks
• Adequate organ and marrow function as defined in the protocol

For Sub-Study 1 Part A:

• Histologically or cytologically confirmed metastatic or locally advanced/recurrent breast cancer, ovarian cancer, CCA or endometrial cancer

For Sub-Study 1 Part B:

• Histologically or cytologically confirmed metastatic or locally advanced and recurrent disease for the respective cohort:

  1. Cohort B1 (Cholangiocarcinoma): at least one prior systemic line of therapy for metastatic/relapsed disease.
  2. Cohort B2 (Serous Ovarian Cancer): at least one prior systemic line of therapy for metastatic/relapsed disease.

  3. Cohort B3 (Triple Negative Breast Cancer): no more than one prior systemic line of therapy for metastatic/relapsed disease.
