| Measure | Time frame |
|---|---|
| Main Objective: To assess the efficacy of durvalumab + dCRT compared with placebo + dCRT in all randomized patients and in patients with PD-L1 High tumors in terms of PFS using BICR assessments according to RECIST 1.1;Secondary Objective: - To assess the efficacy of durvalumab + dCRT compared to placebo + dCRT in all randomized patients and in patients with PD-L1 High tumors in terms of OS, APF24, ORR, DoR, DCR, TTP, PFS2, and OS36 - To assess patient-reported symptoms, functioning, and HRQoL in patients treated with durvalumab + dCRT compared to placebo + dCRT using patient reported outcome measures - To assess the PK of durvalumab when in combination with dCRT in all randomized patients and in patients with PD-L1 High tumors - To investigate the immunogenicity of durvalumab and durvalumab in combination with dCRT in all randomized patients and in patients with PD-L1 High tumors;Primary end point(s): PFS using BICR assessments according to RECIST 1.1 all randomized patients and in patients with PD-L1 High tumors;Timepoint(s) of evaluation of this end point: up to 56 months | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - OS, OS36, PFS2 - APF24,ORR, DoR, DCR and TTP per RECIST 1.1 as assessed by BICR - Time to deterioration and change from baseline in symptoms, functioning, and HRQoL as measured by EORTC QLQ-C30 and QLQ-OES18 - Concentration of durvalumab in blood - ADA (confirmatory results: positive or negative; titers - Presence of ADA for durvalumab (confirmatory results: positive or negative; titers) in all randomized patients and in patients with PD-L1 High tumors;Timepoint(s) of evaluation of this end point: Until end of study | — |
