About KPTI
Karyopharm Therapeutics Inc. is a commercial-stage pharmaceutical company. The Company is engaged in the discovery, development and commercialization of drugs directed against nuclear export for the treatment of cancer. It is developing and commercializing novel, small molecule XPO1 inhibitor compounds that inhibit the nuclear export protein exportin 1 (XPO1). Its lead asset, XPOVIO (selinexor), is marketed in combination with bortezomib and dexamethasone for the treatment of adult patients with multiple myeloma who have received at least one prior therapy. XPOVIO is also marketed for treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL). The Company is engaged in evaluating selinexor in certain hematological and solid tumor malignancies, including myelofibrosis, endometrial cancer and multiple myeloma. The Company’s product candidate, eltanexor, is an oral SINE compound like selinexor, that selectively blocks the nuclear export protein XPO1.

Combination Therapy Shows Significant Spleen Volume Reduction in Myelofibrosis
- Clinical Trial Results: The SENTRY trial demonstrated that the combination of selinexor and ruxolitinib achieved a spleen volume reduction rate (SVR35) of 49.8% at week 24, significantly higher than the control group's 28%, indicating substantial clinical efficacy in myelofibrosis patients.
- Survival Signal: Although the data is immature, preliminary analysis suggests that the selinexor combination therapy reduces the risk of death by over 50% (HR 0.43) compared to ruxolitinib alone, providing potential survival benefits for patients, which is clinically significant.
- Symptom Improvement: The combination therapy showed a comparable improvement in Absolute Total Symptom Score (Abs-TSS) to ruxolitinib alone, although the difference was not statistically significant, indicating the combination's potential in symptom management.
- Safety and Tolerability: The combination demonstrated a manageable safety and tolerability profile consistent with the known characteristics of selinexor and ruxolitinib individually, with no new safety signals observed, enhancing its clinical applicability.
