Experimental: Selinexor, all patients
Single Arm Study, all patients will get selinexor
Selinexor will be administered orally at a dose of 80 mg once weekly until IWG-MR disease progression, intolerable toxicity, or no clinical benefit per treating physician's discretion whichever occurs first.
- Change in spleen volume [ Time Frame: Up to 6 months ]
To assess the efficacy of selinexor on spleen volume reduction in subjects with myelofibrosis (PMF, PET-MF, or PPV-MF) refractory or intolerant to ruxolitinib and/or any other experimental JAK1/2 inhibitors.
Change and percentage change in spleen volume from baseline to EOT as measured by MRI or CT (in applicable patients).
- Adverse Events that Occur [ Time Frame: Up to 6 months ]
To assess the safety/tolerability and further characterize the safety profile of selinexor in PMF, PET-MF, or PPV-MF patients refractory or intolerant to ruxolitinib and/or any other experimental JAK1/2 inhibitors.
Secondary Endpoints: rate of adverse events (AEs) and serious adverse events (SAEs).
- Change in symptoms score [ Time Frame: Up to 6 months ]
Proportion of patients with ≥ 50% reduction of total symptoms score as measured by the MPN-Symptoms Assessment Form (MPN-SAF) from baseline after 6 cycles of treatment.
The score will be reported as one mean score of all of the questions in the questionnaire. The higher the score, the worse the symptom.
- Overall response [ Time Frame: Up to 6 months ]Overall response rate according to the 2013 IWG-MRT consensus criteria for treatment response in primary and secondary MF (post-PV and post-ET).
- Overall Survival [ Time Frame: Up to 24 months ]Overall survival at 24 months from the initiation of study therapy.
