Overview

Luvometinib + cytarabine is an investigational combination regimen being evaluated for the treatment of Langerhans cell histiocytosis (LCH). Luvometinib (FCN-159) is a potent and selective small-molecule inhibitor of MEK1 and MEK2, which are key kinases in the MAPK/ERK signaling pathway. This pathway is frequently dysregulated in histiocytic neoplasms, often due to mutations such as BRAF V600E. Cytarabine is a pyrimidine nucleoside analog that acts as an antimetabolite, interfering with DNA synthesis by inhibiting DNA polymerase and incorporating into DNA strands. The combination is currently being studied in a response-adapted Phase 2 clinical trial sponsored by Shanghai Ninth People's Hospital. In this study, patients receive luvometinib induction, and cytarabine is added for those who do not achieve a complete metabolic response, aiming to improve objective response rates in patients with LCH requiring systemic therapy.
