Blood draw study aims to unravel clot mystery in rare blood cancers
NCT ID NCT06480591
First seen Jun 24, 2026 · Last updated Jul 14, 2026 · Updated 3 times
Summary
This study is collecting blood samples from 35 adults with a type of blood cancer called myeloproliferative neoplasm (MPN) who have a specific genetic mutation (CALR). Researchers want to understand why patients with a different mutation (JAK2) have a higher risk of dangerous blood clots. By measuring certain immune markers in the blood, they hope to find clues about the difference in clot risk.
