metastatic disease not treatable with curative intent.\n  * Has experienced disease progression on or after at least 1 prior endocrine-based therapy in the metastatic setting and received either, 1 line of an approved protocol-specified combination endocrine-based therapy, or 2 or more lines of protocol-specified endocrine-based therapy in the metastatic setting\n* Cohort B:\n\n  * Has histologically confirmed high-grade epithelial (including high-grade serous or predominantly serous, high-grade endometrioid, malignant mixed Müllerian tumors \\[carcinosarcoma\\], or clear cell)

include but are not limited to the following:\n\n* Cohort A:\n\n  * Breast cancer amenable to treatment with curative intent.\n  * Has advanced\u002Fmetastatic, symptomatic visceral spread at risk of rapidly evolving into life-threatening complications, such as lymphangitic lung metastases, radiographic evidence of intratumoral cavitation or invasion\u002Finfiltration of a major blood vessel, bone marrow replacement, carcinomatous meningitis, significant symptomatic liver metastases, symptomatic pericardial effusion, symptomatic peritoneal carcinomatosis, or the need to achieve rapid symptom control.\n* Cohort B:\n\n  * Has nonepithelial cancers (germ cell tumors and sex cord-stromal tumors), borderline tumors (low malignant potential), mucinous, seromucinous that is predominantly mucinous, malignant Brenner's tumor, low-grade serous, low-grade endometrioid, and undifferentiated carcinoma.\n  * Has platinum-resistant ovarian cancer (defined as disease that has progressed per radiographic imaging within 180 days after the last dose of first-line \\[1L\\] platinum-based therapy) or platinum-refractory ovarian cancer (defined as disease that has progressed per radiographic imaging while receiving or within 28 days of the last dose of 1L platinum based therapy).\n  * Is a candidate for curative-intent surgery or curative-intent radiotherapy for ovarian cancer.\n* Cohort
