Summary

This first-in-human open-label, multicenter, dose-escalation and expansion study is designed to evaluate the safety, tolerability, and PK of tiragolumab alone or in combination with atezolizumab and/or other anti-cancer therapies in participants with locally advanced, recurrent, or metastatic incurable tumors for whom standard therapy does not exist, has proven to be ineffective or intolerable, or is considered inappropriate, or for whom a clinical trial of an investigational agent is a recognized standard of care.

Conditions

• Advanced/Metastatic Tumors

Interventions

Type	Name	Description
DRUG	Atezolizumab	Atezolizumab will be given as 1200 mg via IV infusion on Day 1 of each 21-day cycle or as 1680 mg via IV infusion on Day 1 of each 28-day cycle.
DRUG	Tiragolumab	Several dose levels will be evaluated for tiragolumab administered as a single agent and in combination with atezolizumab and/or other anti-cancer therapies. Tiragolumab will be given via IV infusion on Day 1 of each cycle (21-day or 28-day depending on study cohort and phase) until disease progression or loss of clinical benefit. Those who discontinue treatment with single-agent tiragolumab may receive combination treatment with tiragolumab and atezolizumab and/or other anti-cancer therapies. Combination treatment may continue until disease progression or loss of clinical benefit.
DRUG	Carboplatin	Carboplatin, AUC of 6 milligram per milliliter per minute (mg/ml/min) for Cohorts A and B and AUC of 5 mg/ml/min for Cohort C, IV infusion will be administered on Day 1 of each 21-day cycle after combination treatment of atezolizumab and tiragolumab IV infusion.
DRUG	Cisplatin	Cisplatin 75 milligram per square meter (mg/m\^2) IV infusion will be administered on day 1 of each 21-day cycle after combination treatment of atezolizumab and tiragolumab.
DRUG	Pemetrexed	Pemetrexed 500 mg/m\^2 IV infusion will be administered on Day 1 of each 21-day cycle after carboplatin or cisplatin IV infusion with combination treatment of atezolizumab and tiragolumab.
DRUG	Paclitaxel	Paclitaxel 200 mg/m\^2 IV infusion will be administered on Day 1 of each 21-day cycle after combination treatment with atezolizumab and tiragolumab.
DRUG	Etoposide	Etoposide 100 mg/m\^2 IV infusion will be administered on Days 1, 2, and 3 of each 21-day cycle with combination treatment of atezolizumab and tiragolumab.
DRUG	Capecitabine	Capecitabine 1250 mg/m\^2 oral dose will be administered twice daily (BID) on Days 1 through 14 of each 21-day cycle. On Day 1 of Cycle 1, the first dose of capecitabine will be administered prior to the atezolizumab and tiragolumab infusion.
DRUG	Bevacizumab	Bevacizumab 15 mg/kg IV infusion will be administered on Day 1 of each 21-day cycle after combination treatment of atezolizumab and tiragolumab.
DRUG	Pembrolizumab	Pembrolizumab 200 mg IV infusion will be administered on Day 1 of each 21-day cycle after treatment with tiragolumab.
