What was measured
OS was defined as the time from the date of randomization until death due to any cause. Any patient not known to have died at the time of analysis was censored based on the last recorded date on which the patient was known to be alive. Median OS was calculated using the Kaplan-Meier technique. This secondary outcome measure presents OS for the analysis of D + T + EP vs D + EP at the China cohort second analysis DCO (02 November 2020). The alternative treatment comparisons were performed as primary outcome measures.
Analysis population: The China FAS included all randomized patients in the China cohort.
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: D + EP
During Chemotherapy: Patients received durvalumab (D) 1500 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.

- The HR and CIs were calculated using a stratified Cox proportional hazards model, adjusting for planned platinum therapy in Cycle 1 (carboplatin or cisplatin), and ties handled by Efron approach.
- group Description
- D + T + EP vs D + EP. HR \<1 favors D + T + EP to be associated with a longer OS than D + EP. The study was not designed or powered to show statistical significance for efficacy endpoints in the China cohort, so all statistical analyses for the China cohort were considered exploratory.
