Durvalumab: A Review in Extensive-Stage SCLC.

Abstract

Durvalumab (IMFINZI®), a fully human monoclonal antibody against programmed cell death-ligand 1 (PD-L1), is approved for use in combination with etoposide and either carboplatin or cisplatin for the first-line treatment of patients with extensive-stage small cell lung cancer (ES-SCLC). In the pivotal phase III CASPIAN trial in previously untreated adults with ES-SCLC, the addition of durvalumab to chemotherapy for up to 4 cycles followed by maintenance durvalumab was associated with a significantly longer overall survival and a favourable hazard ratio for progression-free survival compared with chemotherapy alone for up to 6 cycles. A higher proportion of patients in the durvalumab plus chemotherapy group had an objective response compared with the chemotherapy alone group. The efficacy of durvalumab was also sustained with longer follow-up. Durvalumab in combination with etoposide and either carboplatin or cisplatin had a manageable tolerability profile in patients with ES-SCLC. Given the available evidence, durvalumab in combination with etoposide and either carboplatin or cisplatin represents a valuable treatment option for the first-line treatment of patients with ES-SCLC, and is an accepted standard of care option in this setting.Supplementary InformationThe online version contains supplementary material available at 10.1007/s11523-021-00843-0.
