• Parts A-2 and B-7 Pembrolizumab Combination Cohorts:
• Diagnosis of clinically relevant immunodeficiency

• Life expectancy ≥12 weeks.
• Patients must have measurable disease per RECIST 1.1.
• Part A-1 cohorts:
• Must have exhausted all standard treatment options, including appropriate targeted therapies; or patients for which no standard therapy is considered appropriate
• Patients with advanced, histologically confirmed urothelial (transitional cell) carcinoma that recurred after or has been refractory to prior therapy (fresh tumor biopsy or an archived sample must be submitted); or
• Patients with advanced, histologically confirmed pancreatic, breast, non-small-cell lung cancer (NSCLC), gastric, esophageal, head and neck, or ovarian tumors that recurred after or has been refractory to prior therapy (fresh tumor biopsy or an archived sample testing for Nectin-4 expression).
• Part A-2:
• Must have exhausted all standard treatment options, including appropriate targeted therapies; or patients for which no standard therapy is considered appropriate
• Patients with advanced, histologically confirmed urothelial (transitional cell) carcinoma that have progressed following prior therapy
• Cohort B-1: Histologically documented urothelial carcinoma, previously treated with enfortumab vedotin (EV). Patients with resectable, locally advanced urothelial carcinoma are ineligible. Must have had progression or recurrence of urothelial cancer during or following receipt of most recent therapy.
• Cohort B-2 and B-3: Histologically documented urothelial carcinoma, not previously treated with enfortumab vedotin (EV). Patients with resectable, locally advanced urothelial carcinoma are ineligible. Must have had progression or recurrence of urothelial cancer during or following receipt of most recent therapy.
• Cohort B-4: Patients with histologically confirmed non-mucinous epithelial ovarian, fallopian tube, or primary peritoneal cancer that is Stage III or IV according to the International Federation of Gynecology and Obstetrics (FIGO) or tumor, node and metastasis staging criteria that have progressed following prior therapy.
• Cohort B-5: Patients with triple-negative breast cancer confirmed negative for estrogen receptor (ER) and progesterone receptor (PR) and negative for human epidermal growth factor receptor 2 (HER2) (i.e., triple-negative) that have progressed following prior therapy.
• Cohort B-6: Patients with histologically confirmed non-small cell lung cancer (NSCLC) with no actionable mutations, such as Epidermal Growth Factor Receptor (EGFR) mutation, anaplastic lymphoma kinase (ALK) fusion oncogene, or ROS1 that have progressed following prior therapy.
• Cohort B-7: Locally advanced or metastatic, histologically confirmed urothelial (transitional cell) carcinoma, ineligible for cisplatin, no prior systemic anticancer treatment for advanced urothelial carcinoma.
• Cohort B-8: Locally advanced (unresectable) or metastatic, histologically confirmed breast cancer, either TNBC or hormone receptor (HR) positive and HER-2 negative according to ASCO/CAP guidelines and up to 3 prior lines of therapy for advanced (unresectable) or metastatic disease.
• Cohort B-9: Histologically confirmed advanced/metastatic squamous or non-squamous NSCLC, negative for oncogenic driver mutations (EGFR, KRAS, ALK, BRAF, MET, ERRB2).
• Cohort C renal insufficiency cohort: Patients with histologically documented urothelial carcinoma, ovarian, triple negative breast, or non-small cell lung cancer that have been previously treated with a locally approved therapy.
• Part D supplementary PK: Patients must have histologically confirmed urothelial (transitional cell) carcinoma (patients with squamous differentiation or mixed cell types are eligible); ovarian; triple-negative breast; or non-small cell lung cancer that have been previously treated with a locally approved therapy.
