Summary
KOSELUGO (selumetinib) is an innovative targeted therapy developed by AstraZeneca primarily for treating neurofibromatosis type 1 (NF1)-related plexiform neurofibromas. Recently, its scope has expanded into off-label uses and experimental treatments for other genetic conditions, such as certain mutations affecting the RAS/MAPK pathway. This analysis provides a comprehensive overview of KOSELUGO’s supply chain, including primary and secondary suppliers, manufacturing details, and key procurement considerations.
Introduction to KOSELUGO and Its Market
KOSELUGO, approved by the FDA in August 2021 for NF1-related plexiform neurofibromas in pediatric patients aged 2 and older, is a potent MEK inhibitor designed to interfere with the RAS/MAPK signaling pathway, which is hyperactive in various tumor types and genetic conditions.
-
Market Size & Growth: The global MEK inhibitors market was valued at approximately USD 1.2 billion in 2022 and is projected to reach USD 2.2 billion by 2027 (CAGR 13%), with KOSELUGO expected to contribute significantly post-commercialization.
-
Regulatory Status: Pending approvals or off-label use pathways vary across regions, impacting supply chain dynamics.
