Fig. 2: Median overall survival for patients with unresectable stage III NSCLC who responded to prior chemoradiotherapy, receiving durvalumab or placebo in the PACIFIC clinical trial.

Shown are Kaplan–Meier curves for median OS, defined according to the RECIST v1.1, and assessed by blinded-independent central review. Tick marks indicate censored observations, and vertical dotted lines indicate the times of landmark OS analyses. The intention-to-treat population included all patients who underwent randomisation. Data cut-off for median OS was March 22, 2018, and median follow-up was 25.2 months. Adapted from Antonia et al.34 Reprinted with permission from Massachusetts Medical Society.
