- Samples were collected post-dose on Day 1 (Week 0), and pre-dose on Weeks 3 and 12. Assessed at the China cohort second analysis DCO (02 November 2020).
What was measured
To evaluate PK, blood samples were collected at pre-specified timepoints and peak and trough serum concentrations of durvalumab were determined. Peak concentration on Week 0 is the post-infusion concentration of Week 0 (collected within 10 minutes of the end of infusion). Trough concentrations on Weeks 3 and 12 are the pre-infusion concentrations of Weeks 3 and 12, respectively.
Analysis population: The China PK analysis set included all patients in the China cohort who received at least 1 dose of IP, per the protocol for whom any post-dose PK data were available. PK for durvalumab was performed for the D + T + EP and D + EP groups only.
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).

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.
