Hope on the Horizon: Emerging Therapies for SCLC
Durvalumab improves overall survival in limited-stage small cell lung cancer following chemoradiotherapy.
Small cell lung cancer (SCLC) is an aggressive malignancy characterized by rapid tumor cell proliferation, early metastasis and poor prognosis. Despite its initial responsiveness to chemotherapy and radiotherapy, recurrence is nearly inevitable, with limited therapeutic advancements over the past decades. Recent breakthroughs have begun to reshape the treatment landscape in SCLC. This review highlights significant clinical trial outcomes and emerging therapeutic strategies for both limited-stage (LS) and extensive-stage (ES) SCLC. The ADRIATIC trial demonstrated a survival benefit of consolidative durvalumab following chemoradiotherapy in LS disease. For ES-SCLC, the CASPIAN and IMpower133 trials proved the efficacy of the PD‑L1 inhibitors durvalumab and atezolizumab when combined with chemotherapy. Nonetheless, the survival benefit remains modest, prompting exploration of novel therapeutic agents. Promising antibody‑drug conjugates, such as ifinatamab deruxtecan (targeting B7‑H3) and sacituzumab govitecan (targeting Trop‑2), along with bispecific T‑cell engagers, such as tarlatamab (targeting DLL3), have demonstrated encouraging efficacy. Moreover, biomarker‑driven approaches, including SLFN11 expression, are under evaluation to guide maintenance therapy. Combination regimens incorporating vascular endothelial growth factor (VEGF) inhibitors such as anlotinib are also gaining attention. These advances suggest a potential shift toward more personalized and effective treatment paradigms, offering new hope for patients with SCLC.
