Condition or disease | Intervention/treatment | Phase |
---|---|---|
Carcinoma, Non-Small-Cell Lung | Drug: Durvalumab + SoC chemotherapy Other: Placebo + SoC chemotherapy | Phase 3 |
Patients who have no evidence of disease recurrence confirmed by CT and/or MRI and are confirmed to meet all eligibility criteria will be randomized 1:1 to durvalumab + Standard of care (SoC) chemotherapy or placebo + Standard of care (SoC) chemotherapy arm.
The primary objective of this study is to assess the efficacy of durvalumab +SoC chemotherapy compared to placebo+ SoC chemotherapy in terms of DFS measured in MRD+ patients.

- Disease free survival (DFS) in MRD+ analysis set (using Investigator assessments according to RECIST 1.1) [ Time Frame: approximately 4 years ]To assess the efficacy of durvalumab + SoC chemotherapy compared to placebo + SoC chemotherapy as measured by DFS in MRD+ patients
- DFS in FAS (using Investigator assessments according to RECIST 1.1) [ Time Frame: Approximately 4 years ]To assess the efficacy of durvalumab + SoC chemotherapy compared to placebo + SoC chemotherapy as measured by DFS in all patients
- DFS (using BICR assessments according to RECIST 1.1) in MRD+ analysis set and in FAS [ Time Frame: Approximately 4 years ]To assess the efficacy of durvalumab + SoC chemotherapy compared to placebo + SoC chemotherapy as measured by DFS in MRD+ patients and in all patients
- OS in MRD+ analysis set and in FAS [ Time Frame: Approximately 6 years ]To assess the efficacy of durvalumab + SoC chemotherapy compared to placebo + SoC chemotherapy as measured by OS in MRD+ patients and in all patients
- Change from baseline in EORTC QLQ-LC13 score [ Time Frame: Approximately 4 years ]To assess patient-reported symptoms, functioning, and HRQoL in MRD+ patients treated with durvalumab + SoC chemotherapy compared to placebo + SoC chemotherapy
- Time to deterioration in EORTC QLQ-LC13 score [ Time Frame: Approximately 4 years ]To assess patient-reported symptoms, functioning, and HRQoL in MRD+ patients treated with durvalumab + SoC chemotherapy compared to placebo + SoC chemotherapy
- Change from baseline in EORTC QLQ-C30 score [ Time Frame: Approximately 4 years ]To assess patient-reported symptoms, functioning and HRQoL in MRD+ patients treated with durvalumab + SoC chemotherapy compared to placebo + SoC chemotherapy
- Time to deterioration in EORTC QLQ-C30 score [ Time Frame: Approximately 4 years ]To assess patient-reported symptoms, functioning, and HRQoL in MRD+ patients treated with durvalumab + SoC chemotherapy compared to placebo + SoC chemotherapy
