- Incidence of dose limiting toxicities (DLTs) [ Time Frame: Subjects will be assessed for DLTs through the end of the first cycle (Days 1-29) ]The Maximum tolerated dose (MTD) or maximum administered dose (MAD) will be determined in patients treated with OMP-313M32 in combination with nivolumab
- Incidence of treatment emergent adverse events [ Time Frame: up to approximately 2 years ]Percentage of patients with adverse events
- Pharmacokinetic Outcome Measures (AUC) - Phase 1a [ Time Frame: 1st dose and 4th dose: pre-dose, post-infusion, and 1, 3, 7 and 10 days. All other doses: pre-dose, 15 minutes and 7 days post-infusion. PK sample will be taken at treatment termination and every 4 wks for 12 wks. ]Area under the plasma concentration versus time curve (AUC) will be evaluated
- Pharmacokinetic Outcome Measures (AUC) - Phase 1b [ Time Frame: 1st dose and 4th dose: pre-dose and 15 minutes post-infusion. All other doses: pre-dose. PK sample will be taken at treatment termination and every 4 wks for 12 wks. ]Area under the plasma concentration versus time curve (AUC) will be evaluated
- Pharmacokinetic Outcome Measures (T1/2) - Phase 1a [ Time Frame: 1st dose and 4th dose: pre-dose, post-infusion, and 1, 3, 7 and 10 days. All other doses: pre-dose, 15 minutes and 7 days post-infusion. PK sample will be taken at treatment termination and every 4 wks for 12 wks. ]The half life (T1/2) of OMP-313M32 will be assessed
- Pharmacokinetic Outcome Measures (T1/2) - Phase 1b [ Time Frame: 1st dose and 4th dose: pre-dose and 15 minutes post-infusion. All other doses, pre-dose.PK sample will be taken at treatment termination and every 4 wks for 12 wks. ]The half life (T1/2) of OMP-313M32 will be assessed
- Immunogenicity of OMP-313M32 [ Time Frame: up to approximately 2 years ]Percentage of patients with anti-OMP-313M32 antibodies assessed
- Objective Response [ Time Frame: up to approximately 2 years ]Measured by Response Evaluation Criteria in Solid Tumors (RECIST 1.1)
- Progression-free survival [ Time Frame: approximately 2 years ]Measured by Response Evaluation Criteria in Solid Tumors (RECIST 1.1)

Exclusion Criteria:
- Anti-cancer therapy, including chemotherapy, hormonal therapy, or radiotherapy, within 3 weeks or 5 half lives, whichever is shorter, prior to initiation of study treatment
