Inclusion Criteria: 1. Histologically or cytologically confirmed advanced (incurable, recurrent, unresectable, or metastatic) solid tumors. 1. For dose escalation cohort patients: patients must have a tumor type as defined in the protocol. Patients will have progression on or after or intolerance to most recent systemic therapy. Patients must have received approved standard therapy that is available to the patient that is known to confer clinical benefit, unless this therapy is contraindicated, intolerable to the patient, or is declined by the patient. The reason for treatment decline must be clearly documented in the medical record. 2. For backfill cohorts: patients must have a tumor type as defined in the protocol. If patients decline an available standard therapeutic regimen known to confer benefit to enroll on this study, the discussion must be clearly documented in the medical record. 2. Measurable disease per RECIST v1.1. Additionally, patients with breast or ovarian cancer with non-measurable, evaluable disease are eligible. 3. ECOG performance status 0-1. 4. Life expectancy of at least 3 months. 5. Willing to provide a pretreatment tumor sample (either an archival sample or a sample obtained by pretreatment biopsy). 6. All toxicity resulting from prior cancer therapies must have resolved to NCI CTCAE v5.0 ≤ Grade 1 or pre-therapy baseline with the exception of alopecia or ≤ Grade 2 neuropathy. 7. Adequate hematological, renal, and hepatic function. 8. Other protocol-defined inclusion criteria apply. Exclusion Criteria: 1. Receiving systemic corticosteroids at prednisone-equivalent dose of \> 10 mg/day within 4 weeks prior to signing consent. Chronic systemic corticosteroid therapy for physiologic replacement (≤ 10 mg/day of prednisone equivalents) and the use of non-systemic corticosteroids (e.g., inhaled, topical, intra-nasal, intra-articular, or ophthalmic) are permitted 2. History of Grade 4 allergic or anaphylactic reaction to prior monoclonal antibody therapy or allergic reaction to any excipients within the investigational product 3. History of toxicity requiring permanent discontinuation of prior cancer immunotherapy 4. Have an active autoimmune disease that has required systemic treatment in past 2 years (replacement therapy is not considered a form of systemic treatment) 5. History of organ or stem cell transplant or need for immunosuppressive treatment 6. Have proteinuria \> 2 + (within 7 days prior to initiation of study treatment). 7. Received any chemotherapy, immunotherapy or investigational anticancer therapy within 3 weeks or 5 half-lives (whichever is shorter; minimum of 2 weeks) prior to first dose of study drug 8. Definitive radiotherapy within 6 weeks and palliative radiation within 2 weeks prior to the first dose of study drug. If previously irradiated, lesions must have demonstrated clear-cut progression prior to being eligible for evaluation as target lesions 9. Other protocol and subprotocol-defined exclusion criteria apply
