Time frame
At baseline, Weeks 3, 6, 9, 12, 16 and 20, then Q4W until PD, on Day 28 and 2 months post-PD, then every 8 weeks until second progression/death (whichever comes first). Assessed until China cohort second analysis DCO (maximum of approximately 29 months).
What was measured
The EORTC QLQ-C30 v3 was included for assessing HRQoL. It assesses HRQoL/health status through 9 multi-item scales: 5 functional scales (physical, role, cognitive, emotional, and social), 3 symptom scales (fatigue, pain, and nausea and vomiting), and a global health and QoL scale. 6 single-item symptom measures are also included: dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties. Scores from 0 to 100 were derived for each of the 15 domains, with higher scores representing greater functioning, greater HRQoL, or greater level of symptoms. Time to deterioration (calculated using the Kaplan-Meier technique) was defined as time from randomization until the date of first clinically meaningful deterioration (a decrease in score from baseline of ≥10) that is confirmed at a subsequent visit or death (by any cause) in the absence of a clinically meaningful deterioration.
Analysis population: The China FAS included all randomized patients in the China cohort. For QLQ-C30 function scales and global health status/HRQoL, only patients with baseline scores ≥10 (and with data available) were included in the analysis. For QLQ-C30 symptom scales/items, only patients with baseline scores ≤90 (and with data available) were included in the analysis.
Groups in this outcome
China Cohort: D + T + EP
During Chemotherapy:
Patients received durvalumab (D) 1500 mg in combination with tremelimumab (T) 75 mg IV infusion Q3W for 4 doses/cycles (Weeks 0, 3, 6 and 9). For chemotherapy (EP), patients received etoposide (80-100 mg/m\^2) with either carboplatin (area under the curve 5-6) or cisplatin (75-80 mg/m\^2) IV infusion Q3W for 4 doses/cycles (Weeks 0, 3, 6 and 9).
Post-Chemotherapy:
Patients then continued to receive durvalumab 1500 mg IV infusion Q4W from Week 12 until PD, unless there was unacceptable toxicity, withdrawal of consent, or another discontinuation criterion was met. Patients also received an additional dose of tremelimumab 75 mg IV infusion post-chemotherapy (in combination with durvalumab) at Week 16 if they completed all 4 doses of durvalumab + tremelimumab during chemotherapy.

China Cohort: EP
For chemotherapy (EP), patients received etoposide (80-100 mg/m\^2) with either carboplatin (area under the curve 5-6) or cisplatin (75-80 mg/m\^2) IV infusion Q3W for 4 doses/cycles (Weeks 0, 3, 6 and 9). An additional 2 doses of EP (at Weeks 12 and 15) could be given at the investigators' discretion if clinically indicated.

description
The EORTC QLQ-C30 v3 was included for assessing HRQoL. It assesses HRQoL/health status through 9 multi-item scales: 5 functional scales (physical, role, cognitive, emotional, and social), 3 symptom scales (fatigue, pain, and nausea and vomiting), and a global health and QoL scale. 6 single-item symptom measures are also included: dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties. Scores from 0 to 100 were derived for each of the 15 domains, with higher scores representing greater functioning, greater HRQoL, or greater level of symptoms. Time to deterioration (calculated using the Kaplan-Meier technique) was defined as time from randomization until the date of first clinically meaningful deterioration (a decrease in score from baseline of ≥10) that is confirmed at a subsequent visit or death (by any cause) in the absence of a clinically meaningful deterioration.

During Chemotherapy:
Patients received durvalumab (D) 1500 mg in combination with tremelimumab (T) 75 mg IV infusion Q3W for 4 doses/cycles (Weeks 0, 3, 6 and 9). For chemotherapy (EP), patients received etoposide (80-100 mg/m\^2) with either carboplatin (area under the curve 5-6) or cisplatin (75-80 mg/m\^2) IV infusion Q3W for 4 doses/cycles (Weeks 0, 3, 6 and 9).
Post-Chemotherapy:
Patients then continued to receive durvalumab 1500 mg IV infusion Q4W from Week 12 until PD, unless there was unacceptable toxicity, withdrawal of consent, or another discontinuation criterion was met. Patients also received an additional dose of tremelimumab 75 mg IV infusion post-chemotherapy (in combination with durvalumab) at Week 16 if they completed all 4 doses of durvalumab + tremelimumab during chemotherapy.
