Karyopharm:Phase 2 Selinexor monotherapy with JAK inhibitor-naive myelofibrosis and thrombocytopenia - Clinical Trial

What is the Purpose of this Study?

We are doing this study to find the most effective, safe dose of an experimental drug called selinexor (the study drug) for people with myelofibrosis (MF).

What is the Condition Being Studied?

Myelofibrosis (MF) and Moderate Thrombocytopenia

Who Can Participate in the Study?

Adults ages 18+ who:

  • Are diagnosed with myelofibrosis
  • Have measurable splenomegaly during the screening period that is defined as a volume of at least 450 cubic centimeters according to MRI or CT scan

What is Involved?

If you decide to participate in this study, you will have a screening visit to see if you are eligibile to join. If you meet the criteria, you will be get a random assignment (like a coin flip) to 1 of 2 groups:

  • One group will get a 40 mg dose of the study drug
  • The other group will get a 60 mg dose of the study drug

The study drug is a tablet that you take by mouth once per week.

Other optional co-therapies (ruxolitinib or pacritinib or momelotinib) may be added to your study drug regimen if you meet certain lab and imaging criteria. All of these drugs are approved treatments for MF.

The following tests and procedures will be performed throughout the study:

  • Physical exams
  • Blood draws
  • Bone marrow biopsies
  • Imaging (CT or MRI)

You will continue taking the study drug regimen for as long as you and your study doctor believe that you are getting a benefit. Participation in the study can last for up to 3 years.
