Summary of clinical efficacy and patient feedback of momelotinib

Momelotinib is an oral small molecule JAK1/JAK2 tyrosine kinase inhibitor, mainly used for the treatment of patients with moderate to severe myelofibrosis (MF). By inhibiting the JAK signaling pathway, the drug reduces bone marrow and peripheral inflammatory responses while regulating blood production, thereby improving patients' symptoms, reducing spleen volume, and increasing hemoglobin levels. Clinical data shows that molotinib can significantly relieve systemic symptoms related to myelofibrosis, including fatigue, night sweats, weight loss, bone pain, etc., and improve patients' quality of life. This provides an important treatment option for patients with limited efficacy of traditional treatment options or for patients with anemia complications.

In terms of efficacy, multiple clinical studies have shown that most patients receiving molotinib can achieve a reduction in spleen volume of at least 35% (SVR35) within 12 to 24 weeks. At the same time, the hemoglobin levels of some patients have been significantly improved, especially those with original anemia, showing the unique advantages of this drug in improving anemia. The myelofibrosis symptom score (TSS) also showed a good improvement effect, and the patients' fatigue, night sweats, abdominal discomfort and bone pain were all relieved. Compared with traditional JAK2 inhibitors, molotinib is more prominent in relieving anemia and improving hematological indicators, which is an important reason why it has attracted much attention in clinical application.

Feedback from patients shows that the oral administration method of molotinib is more convenient, and most patients can better comply with the doctor's instructions to complete the course of treatment. During the first few weeks of use, patients typically experience improved energy, less fatigue, and relief from night sweats, as well as relief from spleen-related symptoms such as abdominal discomfort and fullness. Nonetheless, some patients may experience mild to moderate side effects in the early stages, including diarrhea, nausea, headache, and mild hematological abnormalities such as thrombocytopenia or neutropenia. In most cases, these adverse reactions can be alleviated through dose adjustment, symptomatic treatment, or short-term discontinuation of the drug. Patients generally tolerate these side effects without affecting long-term efficacy.

In clinical practice, the use of molotinib needs to be combined with an individualized plan, including dose adjustment and efficacy evaluation based on hematological indicators, spleen volume changes and symptom scores. Patients should regularly monitor blood routine, liver and kidney function, and symptom changes during medication to ensure drug safety. Long-term follow-up data show that molotinib can maintain the stability of platelet and hemoglobin levels while continuously relieving myelofibrosis symptoms. In the overall clinical evaluation, molotinib has a significant effect in improving the quality of life, relieving symptoms, reducing spleen volume and increasing hemoglobin levels in patients with myelofibrosis. It is a targeted oral drug with important clinical value in the treatment of myelofibrosis, providing an effective and well-tolerated treatment option for moderate to severe patients.
