Condition/Disease
Untreated Extensive-Stage Small Cell Lung Cancer
Objectives
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).

Primary Outcome Measures :
Investigator-Assessed Progression Free Survival (PFS) in the Primary Population [ Time Frame: From randomization to the first occurrence of disease progression or death from any cause, whichever occurs first (up to 50 months) ]
Overall Survival (OS) in the Primary Population [ Time Frame: From randomization to death from any cause (up to 50 months) ]
Secondary Outcome Measures :
PFS in the Intent-To-Treat (ITT) Population [ Time Frame: From randomization to the first occurrence of disease progression or death from any cause, whichever occurs first (up to 50 months) ]
OS in the ITT Population [ Time Frame: From randomization to death from any cause (up to 50 months) ]
Investigator-Assessed Confirmed Objective Response Rate (ORR) in the Primary Population [ Time Frame: From randomization up to 50 months ]
Investigator-Assessed Confirmed ORR in the ITT Population [ Time Frame: From randomization up to 50 months ]
Investigator-Assessed Duration of Response (DOR) in the Primary Population [ Time Frame: From the first occurrence of a documented confirmed objective response to disease progression or death from any cause, whichever occurs first ( up to 50 months) ]
Investigator-Assessed DOR in the ITT Population [ Time Frame: From the first occurrence of a documented confirmed objective response to disease progression or death from any cause, whichever occurs first ( up to 50 months) ]
Investigator-Assessed PFS Rates at 6 Months and 12 Months in the Primary Population [ Time Frame: 6 months, 12 months ]
Investigator-Assessed PFS Rates at 6 Months and 12 Months in the ITT Population [ Time Frame: 6 months, 12 months ]
Overall Survival Rates at 12 Months and 24 Months in the Primary Population [ Time Frame: 12 months, 24 months ]
Overall Survival Rates at 12 Months and 24 Months in the ITT Population [ Time Frame: 12 months, 24 months ]
Time to Confirmed Deterioration (TTCD) Assessed Using European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core (QLQ-C30) Score in the Primary Population [ Time Frame: From randomization until the first confirmed clinically meaningful deterioration up to 50 months ]
TTCD using EORTC QLQ-C30 is an initial 10-point decrease in global health status (GHS)/quality of life (QoL) and functioning from baseline that must be held for at least two consecutive assessments or an initial clinically meaningful decrease above baseline followed by death. EORTC QLQ-C30: a self-reported measure, consisting of 30 questions that assess 5 aspects of participants functioning (physical, emotional, role, cognitive and social), 3 symptom scales (fatigue, nausea and vomiting and pain), GHS and QoL, and 6 single items (dyspnea, insomnia, appetite loss, constipation, diarrhea and financial difficulties) with a recall period of the previous week. Functioning items are scored on a 4-point scale: 1=Not at all to 4=Very much, with higher score indicating worse outcome. Symptom items (GHS and QoL) are scored on a 7-point scale: 1=Very poor to 7=Excellent. Scores will be linearly transformed with a minimum score of 0 and maximum score of 100. Higher score indicates better outcome.
