Introduction: In the phase II ATLANTIC study, durvalumab provided durable responses with acceptable tolerability in heavily pretreated patients with advanced NSCLC, across three independent patient cohorts defined by EGFR/ALK status and tumour PD-L1 expression. Preliminary overall survival (OS) data were encouraging. We now report final OS and updated safety data. Methods: Patients with advanced NSCLC with disease progression following ≥2 previous systemic regimens received durvalumab 10 mg/kg every 2 weeks. The primary endpoint was objective response rate among patients with increased PD-L1 expression (defined as ≥25 % or ≥90 % of tumour cells [TCs], cohort-dependent). Secondary endpoints included OS and safety. Results: 444 patients received durvalumab: 111 in Cohort 1 (EGFR+/ALK+), 265 in Cohort 2 (EGFR−/ALK−), and 68 in Cohort 3 (EGFR−/ALK−; TC ≥ 90 %). Median (95 % CI) OS was 13.3 months (6.3–24.5) in patients with EGFR+/ALK+ NSCLC with TC ≥ 25 %, 10.9 months (8.6–13.6) in patients with EGFR–/ALK– NSCLC with TC ≥ 25 %, and 13.2 months (5.9–not reached) in patients with EGFR–/ALK– NSCLC with TC ≥ 90 %. Median (95 % CI) OS was slightly shorter in patients with TC < 25 % (9.9 months [4.2–13.3] in patients with EGFR+/ALK+ NSCLC and 9.3 months [5.9–10.8] in those with EGFR–/ALK– NSCLC). Treatment-related adverse events of special interest occurred with similar incidences as reported previously. Conclusions: After additional follow-up, final OS data remain encouraging across all cohorts, further supporting the clinical activity of durvalumab in patients with heavily pretreated advanced NSCLC, including those with EGFR+/ALK+ tumours. There were no new safety signals.

Abstract

Introduction: In the phase II ATLANTIC study, durvalumab provided durable responses with acceptable tolerability in heavily pretreated patients with advanced NSCLC, across three independent patient cohorts defined by EGFR/ALK status and tumour PD-L1 expression. Preliminary overall survival (OS) data were encouraging. We now report final OS and updated safety data. Methods: Patients with advanced NSCLC with disease progression following ≥2 previous systemic regimens received durvalumab 10 mg/kg every 2 weeks. The primary endpoint was objective response rate among patients with increased PD-L1 expression (defined as ≥25 % or ≥90 % of tumour cells [TCs], cohort-dependent). Secondary endpoints included OS and safety. Results: 444 patients received durvalumab: 111 in Cohort 1 (EGFR+/ALK+), 265 in Cohort 2 (EGFR−/ALK−), and 68 in Cohort 3 (EGFR−/ALK−; TC ≥ 90 %). Median (95 % CI) OS was 13.3 months (6.3–24.5) in patients with EGFR+/ALK+ NSCLC with TC ≥ 25 %, 10.9 months (8.6–13.6) in patients with EGFR–/ALK– NSCLC with TC ≥ 25 %, and 13.2 months (5.9–not reached) in patients with EGFR–/ALK– NSCLC with TC ≥ 90 %. Median (95 % CI) OS was slightly shorter in patients with TC < 25 % (9.9 months [4.2–13.3] in patients with EGFR+/ALK+ NSCLC and 9.3 months [5.9–10.8] in those with EGFR–/ALK– NSCLC). Treatment-related adverse events of special interest occurred with similar incidences as reported previously. Conclusions: After additional follow-up, final OS data remain encouraging across all cohorts, further supporting the clinical activity of durvalumab in patients with heavily pretreated advanced NSCLC, including those with EGFR+/ALK+ tumours. There were no new safety signals.
