- Significant Efficacy: Karyopharm's SENTRY trial demonstrated that the combination of 60 mg selinexor with ruxolitinib significantly increased the proportion of patients achieving a spleen volume reduction of 35% or more, indicating important clinical relevance in treating myelofibrosis.
- Survival Signal: The combination therapy showed a greater than 50% reduction in the risk of death at 24 weeks, suggesting its potential to improve overall survival rates for patients, which may provide new directions for future treatments.
- Good Safety Profile: No new safety signals were identified in the combination treatment group, and the adverse event rates were consistent with the known safety profiles of selinexor and ruxolitinib used individually, indicating good tolerability.
- Next Steps: Karyopharm plans to meet with the FDA to discuss the totality of the data and its supplemental new drug application, with expectations to submit relevant data in the second half of 2026 to further advance the clinical application of selinexor.
