Top Cities for Myelofibrosis Clinical Trials
Myelofibrosis clinical trials are recruiting across 80 cities. Here are the cities with the most active studies:
About Myelofibrosis
Myelofibrosis is a serious bone marrow disorder that disrupts normal blood cell production, leading to extensive scarring in the bone marrow. It can cause severe anemia, weakness, and an enlarged spleen. Treatment includes JAK inhibitors, blood transfusions, and stem cell transplant.
Clinical trials are advancing new treatments for myelofibrosis. Currently, 14 studies are recruiting a combined 2,882 participants across the United States. Research is being conducted by 10 organizations including Kartos Therapeutics, Inc., Swedish Orphan Biovitrum, Karyopharm Therapeutics Inc and 7 others.
2026 Myelofibrosis Research Landscape
As of March 2026, the myelofibrosis clinical trial landscape includes 14 actively recruiting studies across 80 cities in the United States. These studies are collectively seeking 2,882 participants, with an average enrollment target of 206 per study.
Research is being led by 10 different organizations, including Kartos Therapeutics, Inc., Swedish Orphan Biovitrum, Karyopharm Therapeutics Inc, Geron Corporation, Sumitomo Pharma America, Inc., and 5 others.

Study of Navtemadlin add-on to Ruxolitinib in JAK Inhibitor-Naïve Patients With Myelofibrosis Who Have a Suboptimal Response to Ruxolitinib
This clinical trial is evaluating whether addition of navtemadlin to ruxolitinib treatment will provide more clinical benefit than ruxolitinib alone for patients with Myelofibrosis who have a suboptimal response to ruxolitinib treatment alone. Subjects will start by receiving ruxolitinib alone in the run-in period. Those who demostrate a suboptimal response from ruxolitinib alone will then be ran...
