How much does a box of molotinib/mometinib cost in 2025?

Momelotinib is an oral small molecule drug under development, mainly used to treat myelofibrosis (MF). Myelofibrosis is a myeloproliferative neoplasm in which patients often face problems such as anemia, splenomegaly, and systemic symptoms that seriously affect the patient's quality of life. The mechanism of action of molotinib is mainly by inhibiting two tyrosine kinases, JAK1 and JAK2, thereby regulating signaling pathways related to cell proliferation, inflammatory response and hematopoietic function.

In clinical studies, molotinib has shown good efficacy, especially in reducing splenomegaly and improvingMF-related symptoms. Its unique feature is that it not only inhibits the JAK signaling pathway, but also affects other signaling pathways. For example, by inhibiting ACVR1 (bone morphogenetic protein receptor activin A receptor), it promotes the regulation of hepcidin expression in the liver, thereby improving the utilization efficiency of iron during erythropoiesis. This gives molotinib a potential advantage in addressing anemia, a common and difficult problem.

In addition, early clinical trials have shown that patients using molotinib have also achieved certain results in reducing the need for blood transfusions. This undoubtedly provides new treatment options for MF patients who want to improve their quality of life. Currently, molotinib is undergoing further clinical studies to evaluate its long-term safety and effectiveness.

The original drug of molotinib is not currently on the market in China, so medical insurance cannot cover this drug. However, overseas, there are American versions of original drugs available in various specifications. However, the price is high. Each box may cost about 200,000 yuan, and is also affected by exchange rate fluctuations. Fortunately, the first generic drug of molotinib has been successfully developed and sold. Its ingredients are close to the original drug, such as the 100mg*30 tablets of Lucius Pharmaceuticals in Laos, and the price is more reasonable, only 2,000 yuan per box (The price may fluctuate due to the exchange rate).
