In contrast, an asymptomatic or minimally symptomatic patient with mild or nonspecific leptomeningeal enhancement (MRI) would not be considered to have LMD. In that patient, CSF sampling is not required to formally exclude LMD, but can be performed at the investigator's discretion based on level of clinical suspicion. 3.

Platelet count ≥ 100 × 10^9/L; excluding measurements obtained within 3 days after transfusion of platelets. 3. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 3 × upper limit of normal (ULN). If liver function abnormalities are due to underlying liver metastases, AST and ALT ≤ 5 x ULN. 4. Total serum bilirubin ≤ 1.5 × ULN or ≤ 3 × ULN in the case of Gilbert's disease. 5. Serum creatinine ≤ 1.5 x ULN or creatinine clearance (CrCl) ≥ 60 mL/min. 4. Female subjects of childbearing potential must have a negative serum beta human chorionic gonadotropin test. 5. Male subjects and female subjects of childbearing potential must agree to use an effective method of contraception per institutional standard prior to the first dose and for 90 days after the last dose of ZN-c3. Individuals must meet the additional criteria in order to be eligible to participate in Phase 1: 1. Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2. 2. Measurable or evaluable disease per RECIST version 1.1. Individuals must meet these additional criteria in order to be eligible to participate in Phase 2 Single Agent part of the study: 1. ECOG performance status ≤ 1. 2. Measurable disease per RECIST version 1.1. Individuals must meet these additional criteria in order to be eligible to participate in Phase 2 combination with a PARP inhibitor: 1. ECOG performance status ≤ 1. 2. Measurable disease per RECIST version 1.1. Individuals must meet these additional criteria in order to be eligible to participate in Phase 2 combination with a PD-1 inhibitor: 1. ECOG performance status ≤ 1. 2. Measurable disease per RECIST version 1.1. Key 1. Any of the following treatment interventions within the specified time frame prior to Cycle 1 Day 1: 1. Major surgery within 28 days. 2. Radiation therapy within 21 days. 3. Any prior systemic therapy regardless of the stop date, but the subject must have recovered to eligibility levels from prior toxicity. 4. Autologous or allogeneic stem cell transplant within 3 months. 5. Current use of an investigational agent that is not expected to be cleared by the first dosing of study drug or that has demonstrated to have prolonged side effects. Subjects should have recovered from the side effects to a Grade 0 or 1 (except alopecia). 2. A serious illness or medical condition(s) including, but not limited to, the following: 1. Brain metastases that require immediate treatment or are clinically or radiologically unstable. 2. Leptomeningeal disease that requires or is anticipated to require immediate treatment. 3. Myocardial impairment of any cause resulting in heart failure by New York Heart Association Criteria Class III or IV. 4. Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or study drug administration, or may interfere with the interpretation of study results, and in the judgment of the Investigator would make the subject inappropriate for entry into this study. 5. Significant gastrointestinal abnormalities 6. Active or uncontrolled infection. 3. Unresolved toxicity of Grade > 1 attributed to any prior therapies (excluding Grade 2 neuropathy, alopecia or skin pigmentation). 4. Prior therapy with ZN-c3 or known hypersensitivity to any drugs similar to ZN-c3 in class. 5. Subjects with active (uncontrolled, metastatic) second malignancies or requiring therapy.
