JAK Inhibitors Key in Myelofibrosis,Anemia Treatment
Updated June 29,2025
Managing anemia in patients with myelofibrosis can be guided by findings from a post hoc analysis of the phase 3b JUMP trial,according to Dr. Pankit Vachhani of the University of Alabama at Birmingham. The analysis, presented at the European Hematology Association 2025 Congress earlier this month, explores the role of various treatments in this area.
Vachhani highlighted the multiple options now available, including four Janus kinase (JAK) inhibitors. Momelotinib, as a notable example, is approved for myelofibrosis patients with anemia, though the label does not precisely define anemia. Ruxolitinib, another JAK inhibitor, has demonstrated long-term data, including overall survival benefits.It is the most commonly used and studied JAK inhibitor, assessed across a range of hemoglobin levels, even in transfusion-dependent patients during the COMFORT studies.
The JUMP data analysis indicates that while anemia is detrimental, a ruxolitinib plus erythropoietin-stimulating agent (ESA) approach can definitely help maintain high doses of ruxolitinib, which are necessary for positive clinical outcomes. This combination allows for maintaining hemoglobin levels within 1 g/dL of baseline.
Vachhani emphasized the importance of personalizing treatment for each patient, considering comorbidities, insurance approvals, and logistical factors.He noted that a 101-patient data set supports the combination of ruxolitinib and ESA as a viable strategy to counter both myelofibrosis and anemia.
“I guess, for any individual patient, though, my suggestion, as always, will be to personalize the treatment approach. Look at their comorbidities, look at what the insurance approves, look at the logistics of doing this, but know that, there [are] data now…that supports this combination as one of the ways that we can counter myelofibrosis and anemia together,” Vachhani said.
What’s next
Future research should focus on newer treatments targeting iron homeostasis through hepcidin pathways and erythropoiesis to improve anemia outcomes further. Researchers aim to correlate improvements in hemoglobin levels with tangible survival benefits. Additional drug combinations should also be tested to surpass the capabilities of current drugs and regimens. The development of more selective JAK inhibitors may help prevent anemia-related complications in the first place, according to Vachhani.
