Can a targeted drug outperform standard care for rare blood cancers?
NCT ID NCT02577926
First seen Aug 13, 2026 · Last updated Aug 14, 2026 · Updated 1 time
Summary
This trial compares the drug ruxolitinib against the best available standard treatments for people with high-risk polycythemia vera (PV) or essential thrombocythemia (ET), two rare blood cancers that cause overproduction of blood cells and can lead to clots, bleeding, and severe symptoms. Participants receive either ruxolitinib or a standard therapy chosen by their doctor, such as hydroxyurea or interferon. The main goal is to see if ruxolitinib leads to a higher rate of complete clinicohematologic response, meaning better control of blood counts and symptoms, while also monitoring side effects.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Ruxolitinib, a JAK1/2 inhibitor, compared to best available therapy (e.g., hydroxyurea, anagrelide, interferon).
- What this could lead to
- If successful, ruxolitinib could become a more effective treatment option for high-risk PV and ET, potentially improving symptom control and reducing complications.
- What could go wrong
- This is a phase 2 trial, so results are preliminary. Ruxolitinib may not prove superior to existing therapies, and it carries risks like infection and blood count changes.
