NCT ID NCT05714072

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This early-phase trial is testing whether adding abemaciclib to the standard drug ruxolitinib is safe and effective for people with myelofibrosis, a type of bone marrow cancer. The study will enroll 18 adults who have been on ruxolitinib for at least 12 weeks. Researchers will monitor for side effects and measure how well the combination controls the disease.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

ruxolitinib and abemaciclib

What this could lead to

If it works, this could offer a new treatment option for people with myelofibrosis who are already on ruxolitinib.

What could go wrong

This is a very early phase 1 trial with only 18 participants, so safety and effectiveness are not yet proven. The drug combo may cause side effects or not work better than existing treatments.
