Brief Summary:
This study will evaluate the combination of a fixed dose pembrolizumab/vibostolimab co-formulation (MK-7684A) with etoposide/platinum chemotherapy followed by MK-7684A compared to the combination of atezolizumab with etoposide/platinum chemotherapy followed by atezolizumab in the first-line treatment of Extensive-Stage Small Cell Lung Cancer (ES-SCLC). The primary hypothesis is, with respect to overall survival, MK-7684A in combination with the background therapy of etoposide/platinum followed by MK-7684A, is superior to atezolizumab in combination with the background therapy of etoposide/platinum followed by atezolizumab.

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.

Primary Outcome Measures :
- Overall Survival (OS) [ Time Frame: Up to approximately 37 months ]Overall Survival (OS) is the time from randomization to the date of death due to any cause.
Secondary Outcome Measures :
- Progression-Free Survival (PFS) [ Time Frame: Up to approximately 26 months ]Progression-Free Survival (PFS) is the time from randomization to the first documented disease progression (PD) or death due to any cause, whichever occurs first.
- Objective Response Rate (ORR) [ Time Frame: Up to approximately 37 months ]Objective Response Rate (ORR) is the percentage of participants who have a Complete Response (CR) (disappearance of all target lesions) or a Partial Response (PR) (at least a 30% decrease in the sum of diameters of target lesions).
- Duration of Response (DOR) [ Time Frame: Up to approximately 37 months ]Duration of Response (DOR) is the time from first documented evidence of CR (disappearance of all target lesions) or PR (at least a 30% decrease in the sum of diameters of target lesions), until progressive disease (PD) or death.
- Percentage of Participants Who Experienced an Adverse Event (AE) [ Time Frame: Up to approximately 60 months ]An AE is any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure, that occurs during the course of the study.
- Percentage of Participants Who Discontinued Study Treatment Due to an AE [ Time Frame: Up to approximately 60 months ]An AE is any unfavorable and unintended sign including an abnormal laboratory finding, symptom or disease associated with the use of a medical treatment or procedure, regardless of whether it is considered related to the medical treatment or procedure, that occurs during the course of the study.
- Change from Baseline in the Global Health Status/Quality of Life (Items 29 and 30) Combined Score on the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) [ Time Frame: Baseline and up to approximately 37 months ]The EORTC-QLQ-C30 is a 30-item questionnaire developed to assess the quality of life (QoL) of individuals with cancer.
