What is being measured
The primary outcome is the main question the study is designed to answer.
Proportion of Participants with Spleen Volume Reduction ≥35% (SVR35) at Week 24
Measured by Magnetic Resonance Imaging (MRI) or Computed Tomography (CT) Scan by Investigator assessment.
Measured: At Week 24
Secondary outcomes (2)
Absolute Mean Change in Total Symptom Score (Abs-TSS) from baseline to Week 24
Measured by the Myelofibrosis Symptom Assessment Form (MFSAF) V4.0.
Measured: At Baseline and Week 24
Incidence and severity of TEAEs, including TRAEs and SAEs
Measured by the NCI CTCAE Grading Scale, v. 5, as assessed and graded by the Investigator
Measured: From Baseline to EoS (approximately 48 months)

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Selinexor 60 mg, Selinexor 40 mg and Ruxolitinib in people with Myelofibrosis and Moderate Thrombocytopenia, run by Karyopharm Therapeutics Inc at 70 sites in 19 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 12 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 12 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 70 sites in Italy, France, Spain, United States, Bulgaria and 14 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Karyopharm Medical Information ((888) 209-9326, clinicaltrials@karyopharm.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Proportion of Participants with Spleen Volume Reduction ≥35% (SVR35) at Week 24 (time frame: At Week 24). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Feb 2026.
