Part B: 1. Cohort 1B: Histologically-diagnosed locally advanced (unresectable) or metastatic ccRCC that has progressed following all available standard therapy (e.g., anti-PD(L)-1, anti-vascular endothelial growth factor [VEGF] kinase inhibitors), or if no further standard therapy exists. 2. Cohort 2B: Histologically-diagnosed locally advanced (unresectable) or metastatic, platinum-resistant epithelial ovarian, fallopian tube or primary peritoneal carcinoma (i.e., disease recurrence within 6 months of completion of platinum-based therapy) that has progressed following all available standard therapy, or if no further standard therapy exists. 3.

Life expectancy = 12 weeks 5. Part A: Patients without RECIST measurable disease (e.g., evaluable disease only) will be eligible for enrollment in Part A, regardless of tumor type; Part B: Patients enrolled in Part B must have measurable disease by per RECIST 1.1 and have = 1 site of measurable disease that has not been previously irradiated. Key Exclusion Criteria: 1. Females who are pregnant (positive serum pregnancy test within 7 days prior to study drug administration) or breastfeeding. 2. Immune Related Medical History: 1. Active autoimmune disease that has required systemic disease-modifying or immunosuppressive treatment within the last 2 years 2. Receipt of systemic immunosuppressive therapy (e.g. steroids) within 4 weeks prior to the start of study drug administration 3. History of idiopathic pulmonary fibrosis, interstitial lung disease, organizing pneumonia, non-infectious pneumonia that required steroids, or evidence of active, non-infectious pneumonitis 4. History of Grade = 3 immune-mediated toxicity 3. Prior allogeneic or autologous bone marrow transplant, or other solid organ transplant. 4. History of a positive test for: 1. Hepatitis C virus (HCV) infection, except for those who have completed curative therapy for HCV and have undetectable HCV RNA 2. Hepatitis B virus (HBV) infection, except for those who are receiving treatment with HBV-active nucleos(t)ide antiviral therapy at the time of study entry and have undetectable HBV DNA 3. Human Immunodeficiency Virus (HIV) infection, except those who meet the following criteria: CD4+ T cells = 350 cells/µL, no history of Acquired Immunodeficiency Syndrome (AIDS)-defining opportunistic infections, HIV RNA < 50 copies/mL, and on a stable antiretroviral regimen for at least 3 months. 5. Prior radiation therapy with an inadequate washout between the last dose and the start of study drug, defined as follows: 1) at least 2 weeks for palliative radiation to the extremities for osseous bone metastases is required; 2) at least 4 weeks for radiation to the chest, brain, or visceral organs is required; and 3) at least 6 weeks for large-field radiation is required. 6. Prior anticancer therapy, including chemotherapy, targeted therapy, biological therapy or immune-checkpoint inhibitors within 4 weeks or 5 drug half-lives (whichever is shorter) 7. History of another malignancy in the previous 2 years, unless cured by surgery alone and continuously disease free. 8. Recent history of cardiovascular disease 9. Uncontrolled or symptomatic CNS (central nervous system) metastases and/or carcinomatous meningitis |
