Conditions

Interventions

DRUG

Atezolizumab

Atezolizumab will be administered to participants by IV infusion at a fixed dose starting on Day 22 of Cycle 1. In subsequent cycles (Cycles 2 and beyond), IV atezolizumab will be given every 2 weeks (Q2W) on Days 8 and 22 of each 28-day cycle.

DRUG

Hu5F9-G4

Two priming doses of 1 mg/kg of Hu5F9-G4 will be administered to participants by continuous IV infusion on Days 1 and 4 of Cycle 1, followed by loading doses of 15 mg/kg IV on Day 8 and 30 mg/kg IV on Day 11. Starting on Day 15 of Cycle 1, Hu5F9-G4 maintenance will be given by IV infusion at a dose of 30 mg/kg once a week (QW) of each 28-day cycle. Dosing for de-escalation, if needed: Hu5F9-G4 will be given as two priming doses of 1 mg/kg IV on Days 1 and 4, followed by loading doses of 10 mg/kg IV on Day 8 and 15 mg/kg on Day 11. Starting on Day 15, maintenance treatment with Hu5F9-G4 will be given by IV infusion at a dose of 15 mg/kg once a week (QW).
