Durvalumab has been proven to enhance T-cell activation in vitro and reduce tumor size in co-engrafted human tumor and immune cell xenograft mouse models. Clinical evidence The safety and efficacy of durvalumab were evaluated in a clinical trial involving 730 LS-SCLC patients. The drug demonstrated superiority over a placebo in achieving higher overall survival (55.9 vs.
