Description of intervention(s) / exposure
Treatment: Drugs - RO7502175
Treatment: Drugs - Atezolizumab

Experimental: Phase Ia: Dose Escalation - Participants in successive cohorts will receive escalating doses of RO7502175, as an intravenous (IV) infusion on Day 1 of each 21-day cycle until disease progression or unacceptable toxicity.

Experimental: Phase Ia: Expansion - Participants with select solid tumors will receive a recommended dose of RO7502175, determined in Phase Ia Dose Escalation phase as an IV infusion on Day 1 of each 21-day cycle until disease progression or unacceptable toxicity.

Experimental: Phase Ib: Dose Escalation - Participants in successive cohorts will receive escalating doses of RO7502175, 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.

Experimental: Phase Ib: Expansion - Participants with select solid tumors will receive a recommended dose of RO7502175, determined in Phase Ib 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.

Summary
Brief summary
This is a first-in-human study to evaluate the safety, tolerability, pharmacokinetics (PK),
and anti-tumor activity of RO7502175 when administered as a single agent and in combination
with atezolizumab in adult participants with locally advanced or metastatic solid tumors,
including non-small-cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC),
melanoma, triple-negative breast cancer (TNBC), esophageal cancer, gastric cancer, cervical
cancer, urothelial carcinoma (UC), clear cell renal cell carcinoma (RCC) and hepatocellular
carcinoma (HCC). Participants will be enrolled in 2 stages: dose escalation and dose
expansion.
