Summary: This study will evaluate the efficacy of tiragolumab plus atezolizumab and carboplatin and etoposide (CE) compared with placebo plus atezolizumab and CE in participants with chemotherapy-naive extensive-stage small cell lung cancer (ES-SCLC). Eligible participants will be randomized in a 1:1 ratio to receive one of the following treatment regimens during induction phase:- - Arm A: Tiragolumab plus atezolizumab and CE - Arm B: Placebo plus atezolizumab and CE Following the induction phase, participants will continue maintenance therapy with either atezolizumab plus tiragolumab (Arm A) or atezolizumab plus placebo (Arm B).

Inclusion Criteria:

- Active hepatitis B or hepatitis C

- Severe infection at the time of randomization

- Treatment with any other investigational agent within 28 days prior to initiation of study treatment

- Prior treatment with CD137 agonists or immune checkpoint blockade therapies, anti-CTLA-4, anti-TIGIT, anti-PD-1, and anti-PD-L1 therapeutic antibodies

- Treatment with systemic immunostimulatory agents within 4 weeks or 5 drug elimination half-lives prior to randomization
