Description of intervention(s) / exposure
Treatment: Other - Pembrolizumab/Vibostolimab Co-Formulation
Treatment: Drugs - Saline placebo
Treatment: Drugs - Etoposide
Treatment: Drugs - Cisplatin
Treatment: Other - Atezolizumab
Treatment: Drugs - Carboplatin

Experimental: Pembrolizumab/Vibostolimab - Participants will receive 4 cycles (each cycle is 3 weeks) of a fixed-dose coformulation of 200 mg pembrolizumab and 200 mg vibostolimab (MK-7684A) every 3 weeks (Q3W), in combination with 100 mg/m\^2 etoposide, and platinum (Area Under the Curve (AUC) 5 mg/mL/min carboplatin or 75 mg/m\^2 cisplatin) chemotherapy Q3W for a total of approximately 12 weeks. This will be followed by additional cycles of MK-7684A Q3W until any of the conditions for discontinuation are met. To maintain the blinding, saline placebo will be administered on cycle 1 day 1 and then Q3W as needed beyond cycle 1.

Active comparator: Atezolizumab - Participants will receive 4 cycles (each cycle is 3 weeks) of 1200 mg atezolizumab Q3W, in combination with 100 mg/m\^2 etoposide and platinum (AUC 5 mg/mL/min carboplatin or 75 mg/m\^2 cisplatin) chemotherapy Q3W for a total of approximately 12 weeks. This will be followed by additional cycles of atezolizumab Q3W until any of the conditions for discontinuation are met. To maintain the blinding, saline placebo will be administered on cycle 1 day 1 and then Q3W as needed beyond cycle 1.


Treatment: Other: Pembrolizumab/Vibostolimab Co-Formulation
Pembrolizumab 200 mg plus vibostolimab 200 mg fixed dose coformulation administered via IV infusion Q3W on Day 1 of each cycle until discontinuation criteria are met.

Treatment: Drugs: Saline placebo
Saline solution administered via IV infusion on Cycle 1 (and Q3W as needed beyond Cycle 1)

Treatment: Drugs: Etoposide
Etoposide 100 mg/m\^2 administered via IV infusion Q3W on Days 1 2, 3 of each cycle for up to 4 cycles

Treatment: Drugs: Cisplatin
Cisplatin 75 mg/m\^2 administered via IV infusion Q3W on Day 1 of each cycle for up to 4 cycles.

Treatment: Other: Atezolizumab
Atezolizumab 1200 mg administered via IV infusion Q3W on Day 1 of each cycle until discontinuation criteria are met.

Treatment: Drugs: Carboplatin
Carboplatin AUC 5 mg/mL/min administered via IV infusion Q3W on Day 1 of each cycle for up to 4 cycles.
