Ongoing Clinical Trials for Myelofibrosis

This article provides detailed information about 30 ongoing clinical trials for myelofibrosis, a rare bone marrow disorder. These trials are testing various medications and treatment combinations across multiple countries in Europe, offering new hope for patients who have not responded well to current therapies or are seeking alternative treatment options.

Clinical trial locations

Continued Treatment Study for Patients with Myelofibrosis, Post-Lung Transplant BOS, or Chronic Graft-Versus-Host Disease Using Itacitinib

This study provides continued access to itacitinib for patients who have previously participated in trials involving this medication and are benefiting from treatment. The trial includes patients with myelofibrosis, post-lung transplant bronchiolitis obliterans syndrome, or chronic graft-versus-host disease.

Summary

This overview highlights 30 ongoing clinical trials for myelofibrosis across multiple European countries. Several notable patterns emerge from the data. Italy, Germany, France, and Spain feature prominently as trial locations, with Italy hosting at least 10 trials. Poland, Belgium, and Romania also have significant trial activity.

Many trials focus on patients who have not responded adequately to JAK inhibitor therapy, particularly ruxolitinib, which is a current standard treatment. Several studies investigate combination therapies, such as navtemadlin with ruxolitinib, selinexor with ruxolitinib, and navitoclax with ruxolitinib. There is also interest in developing treatments for patients with severe thrombocytopenia and anemia associated with myelofibrosis.

The trials employ various approaches, including telomerase inhibitors, kinase inhibitors, and targeted therapies. Several extension studies provide continued access to investigational medications for patients benefiting from previous trials. The research aims to improve outcomes for patients with intermediate-2 or high-risk myelofibrosis, particularly those with limited treatment options.
