Company Update (NASDAQ:KPTI): Karyopharm Therapeutics Inc Presents Preliminary STOMP Phase 1b Clinical Data at 2016 EHA Annual Meeting

Karyopharm Therapeutics Inc (NASDAQ:KPTI), a clinical-stage pharmaceutical company, today announced a poster presentation highlighting updated clinical data from the Company’s ongoing Phase 1b study of selinexor (KPT-330), a first-in-class, oral Selective Inhibitor of Nuclear Export / SINE™ compound that inhibits exportin 1 (XPO1), and dexamethasone in combination with standard of care agents in heavily pretreated patients with relapsed/refractory multiple myeloma (MM) (the STOMP study), including patients with proteasome inhibitor and immunomodulatory agent (IMiD) refractory MM.  The Company also presented two e-posters featuring preclinical data for its second-generation SINE™ compound, KPT-8602.  These data sets were presented at the 21st Congress of theEuropean Hematology Association (EHA) held June 9-12, 2016 in Copenhagen, Denmark.

“We are highly encouraged by the promising, durable activity and safety we continue to observe in the STOMP trial,” said Sharon Shacham, PhD, MBA, President and Chief Scientific Officer of Karyopharm. “Selinexor and dexamethasone in combination with backbone therapies, such as bortezomib and pomalidomide, has the potential to provide a new treatment option for multiple myeloma, even in heavily pretreated patients whose disease has progressed on these standard agents.  We look forward to reporting additional top-line data from the Phase 1b portion of this study in late 2016, with the accompanying goal of determining the recommended Phase 2 doses for several of these combinations.”

In the poster, titled “A Phase 1b/2 Study of Selinexor in Combination with Backbone Therapies for Treatment of Relapsed/Refractory Multiple Myeloma,” Dr. Nizar Bahlis of the Southern Alberta Cancer Research Institute and colleagues, for the first time described clinical data from the ongoing Phase 1b/2 STOMP study of selinexor and dexamethasone in combination with bortezomib (Velcade®), pomalidomide (Pomalyst®), or lenalidomide (Revlimid®) in heavily pretreated relapsed/refractory MM patients.  High response rates were reported for the selinexor + dexamethasone + bortezomib (SdB) and selinexor + dexamethasone + pomalidomide (SdP) arms; data are early for the ongoing selinexor + dexamethasone + lenalidomide (SdL) arm.

Dr. Bahlis commented, “We are particularly impressed with the high level of durable activity of selinexor in combination with bortezomib, particularly in patients whose disease is refractory to proteasome inhibitors.  In addition, the preliminary results show that selinexor can combine with pomalidomide with good tolerability and strong responses.  Together, these data indicate that selinexor can be added to standard treatments for patients with myeloma with high rates of anti-tumor activity, consistent with preclinical results showing that selinexor can reverse resistance to other therapies.” (Original Source)
