Are momelotinib and molotinib the same medicine?

momelotinib and molotinib are actually the same drug. "momelotinib" is its common English name, and "molotinib" is its Chinese translation. The two are completely consistent in terms of clinical, pharmacological and action mechanisms, but the name expression is different, which is commonly used in different contexts: "momelotinib" is used in English materials or international registrations, while in Chinese literature, drug descriptions or media reports, it is mostly called "molotinib".

Molotinib is a JAK1, JAK2 and ACVR1 inhibitor, primarily used to treat patients with myelofibrosis (Myelofibrosis). The disease is a rare myeloproliferative neoplasm that often presents with severe anemia, splenomegaly, and systemic symptoms. Molotinib relieves symptoms and improves hematology by inhibiting the abnormal activation of the JAK-STAT pathway. At the same time, its ability to alleviate anemia is a major clinical advantage, which is different from other JAK inhibitors such as ruxolitinib (Ruxolitinib).

momelotinib has been approved for marketing by the US FDA in 2023 and has become the first JAK inhibitor with a clear alleviation effect on anemia. This also gives molotinib a unique position in the treatment of myelofibrosis, especially for patients with moderate to severe anemia. At present, the drug has been launched in many regions around the world, but it has not been officially approved for use in mainland China. Patients usually need to obtain it through overseas medical channels if they need it.

In short, momelotinib and momelotinib are the same drug, just different expressions of the English and Chinese names. Knowing this can avoid confusion when researching information or purchasing medications. No matter which name is used, patients should use such targeted drugs under the guidance of doctors and comprehensively evaluate whether they are suitable for molotinib treatment based on their own condition, drug availability and price.
