The single-arm, phase 2 PACIFIC-6 trial (NCT03693300) found that durvalumab after sequential chemoradiotherapy (sCRT) had comparable safety profile to concurrent chemoradiotherapy reported by the PACIFIC trial (NCT02125461) and revealed encouraging efficacy for stage III, unresectable NSCLC. 1 Garassino M.C.
