Finding immune markers in blood cell disorders
This research study looks for specific immune system clues in patients with myeloproliferative neoplasms—rare blood disorders where your bone marrow produces too many blood cells. By identifying these markers, researchers hope to better understand and eventually treat these conditions.
Brussels, WoluweAges 18 years+ - NCT06734637Recruiting
Peginterferon for essential thrombocythemia and polycythemia vera
This trial tests a medicine called peginterferon for people with two blood disorders: essential thrombocythemia (too many platelets) and polycythemia vera (too many red blood cells). The goal is to see if peginterferon can help control these conditions and is safe.
Wuhan, HubeiAges 18 years+ - NCT07469891RecruitingPhase 1
Study of a new drug for myelofibrosis and polycythemia vera
This study tests an experimental pill called PRT12396 for people with myeloproliferative neoplasms (MPN). It aims to see if the drug is safe and helps control the disease.
Los Angeles, CaliforniaAges 18 years+ - NCT06976918Recruiting
Myelofibrosis and Anemia Research Study
This study follows people with myelofibrosis and anemia who are starting a new treatment. It aims to learn more about the disease and how treatments work in real life.

Combination treatment for advanced myeloproliferative neoplasms
This study tests whether adding a new drug called iadademstat to the standard treatment ASTX727 helps people with advanced myeloproliferative neoplasms (blood cancers that cause the bone marrow to make too many cells). The goal is to see if the combination is safe and works better than the standard treatment alone.

Common questions
- Are there clinical trials for essential thrombocythemia?
- Yes. Clin2 currently lists 32 recruiting essential thrombocythemia studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a essential thrombocythemia trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a essential thrombocythemia trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
