Selpercatinib: A Review in Advanced RET Fusion-Positive NSCLC.

Abstract

Selpercatinib (Retevmo®/Retsevmo®) is an orally-administered, selective inhibitor of rearranged during transfection (RET) kinase approved for the treatment of advanced RET fusion-positive non-small cell lung cancer (NSCLC). In a pivotal phase 1/2 clinical trial in this population, selpercatinib treatment was associated with robust and durable responses, including intracranial responses, in patients previously treated with platinum-based chemotherapy, as well as in treatment-naïve patients. Selpercatinib had a manageable tolerability profile and an acceptable safety profile; adverse events could generally be managed with dose reductions and only a small proportion of patients discontinued selpercatinib due to treatment-related adverse events. The most common treatment-related adverse events that were grade 3-4 in severity were hypertension, elevated alanine aminotransferase and elevated aspartate aminotransferase. Thus, currently available evidence suggests that selpercatinib is a promising new RET-targeted therapy option for patients with advanced RET fusion-positive NSCLC.
