Description of intervention(s) / exposure
Treatment: Drugs - RO7566802
Treatment: Drugs - Atezolizumab

Experimental: Dose Escalation Cohort - Participants in successive cohorts will receive escalating doses of RO7566802, as an intravenous (IV) infusion on Day 1 of each 21-day cycle followed by RO7566802 in combination with a fixed dose of atezolizumab, as an IV infusion on Day 1 of each 21-day cycle until disease progression or unacceptable toxicity.

Experimental: Dose Expansion Cohort - Participants with select solid tumors will receive a recommended dose of RO7566802, determined in Dose Escalation phase, as an IV infusion in combination with a fixed dose of atezolizumab, as an IV infusion on Day 1 of each 21-day cycle until disease progression or unacceptable toxicity.
