Koselugo
Koselugo was approved for the following therapeutic use:
Koselugo is indicated for the treatment of paediatric patients aged 2 years and above, with neurofibromatosis type 1 (NF1) who have symptomatic, inoperable plexiform neurofibromas (PN).
Selumetinib is an orally available, inhibitor of mitogen activated protein kinase kinases 1 and 2 (MEK1/2) that is not competitive with respect to adenosine triphosphate (ATP). MEK1/2 proteins are critical components of the reticular activating system (RAS)-regulated rapidly accelerated fibrosarcoma (RAF)-mitogen activated protein kinase (MEK)-extracellular signal regulated kinases (ERK) pathway, which is often activated in different types of cancers. Selumetinib blocks MEK activity and inhibits growth of RAF-MEK-ERK pathway activated cell lines. Therefore, MEK inhibition can block the proliferation and survival of tumour cells in which the RAF-MEK-ERK pathway is activated.
The decision was based on nonclinical (pharmacology and toxicology), clinical (pharmacology, safety and efficacy) and risk management plan information submitted by the sponsor. The benefit-risk profile of Koselugo was considered favourable for the therapeutic use approved.
