Momelotinib under the microscope: Real-World spleen shrinkage in myelofibrosis
NCT ID NCT07249606
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study will observe 93 adults with myelofibrosis who are taking momelotinib as part of their normal care. Researchers will track how well the drug reduces spleen size after 6 months, providing real-world evidence of its effectiveness.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- momelotinib
- What this could lead to
- If successful, this study could confirm that momelotinib effectively reduces spleen size in everyday clinical practice, supporting its use for myelofibrosis.
- What could go wrong
- This is an observational study, not a controlled trial, so results may be less reliable. It is also small (93 people) and not yet recruiting, so findings may not apply broadly.
