Description of intervention(s) / exposure
Treatment: Drugs - GDC-1971
Treatment: Drugs - Atezolizumab
Treatment: Drugs - Omeprazole

Experimental: Dose-finding Stage: GDC-1971 - Participants will receive GDC-1971 tablet or capsule at assigned dose, orally once daily (QD) on Days 1-21 of each cycle, along with atezolizumab 1200 milligrams (mg) intravenous (IV) infusion once every 3 weeks (Q3W), until unacceptable toxicity or loss of clinical benefit. A subset of participants will participate in evaluations regarding tablet versus (vs) capsule formulations.

Experimental: Expansion Stage: GDC-1971 - Participants will receive GDC-1971 orally at the assigned dose QD on Days 1-21 of each cycle and atezolizumab 1200 mg IV on Day 1 of each cycle until unacceptable toxicity or loss of clinical benefit. A subset of participants will participate in evaluations regarding tablet vs capsule formulation, the effect of food and acid-reducing agents on GDC-1971.


Treatment: Drugs: GDC-1971
Capsule or tablet administered orally.

Treatment: Drugs: Atezolizumab
Administered as IV infusion.

Treatment: Drugs: Omeprazole
Administered orally as tablet or capsule in the acid-reducing agent assessment.

Summary
Brief summary
The purpose of this study is to evaluate the safety, pharmacokinetics (PK), and activity of
GDC-1971 when administered in combination with atezolizumab in participants with locally
advanced or metastatic solid tumors.

The study will have 2 stages- dose finding stage and expansion stage. In expansion stage
participants with non-small cell lung cancer programmed death ligand -1 high (NSCLC PD L-1
high), NSCLC PD L-1 low, head and neck squamous cell carcinoma (HNSCC) PD L-1 positive, BRAF
wild type (BRAF WT) melanoma and any locally advanced or metastatic solid tumors will be
enrolled.
