Karyopharm to Ring the Nasdaq Stock Market Closing Bell

NEWTON, Mass., Nov. 02, 2016 (GLOBE NEWSWIRE) -- Karyopharm Therapeutics Inc. (Nasdaq:KPTI), a clinical-stage pharmaceutical company, today announced that company executives, including founder Sharon Shacham PhD, MBA, President and Chief Scientific Officer and cofounder Michael G. Kauffman MD, PhD, Chief Executive Officer, will ring the Nasdaq Closing Bell at 4:00 p.m. ET on Friday, November 4, 2016 at the Nasdaq MarketSite in New York City to commemorate the eighth anniversary of the Company's founding.

"We are honored to participate in the Nasdaq Closing Bell ceremony in celebration of Karyopharm's anniversary," said Dr. Kauffman.  "Eight years ago, Sharon founded Karyopharm with the discovery of novel small molecules inhibiting the nuclear export protein XPO1 as a novel anti-cancer strategy.  Since that time, the Karyopharm team has significantly advanced a pipeline of SINE compounds, including selinexor, our lead product candidate, which is being evaluated in multiple mid- and later-phase clinical indications in over 1,800 patients across several high unmet need cancer indications.  Looking ahead, we are in preparations to expand our ongoing Phase 2b clinical trial in heavily pretreated, penta-refractory multiple myeloma, and to initiate a pivotal Phase 3 clinical trial evaluating selinexor in patients with early relapsed myeloma, with the goal of obtaining regulatory approval and providing a much-needed oral treatment option for patients suffering with this incurable disease."

Karyopharm's SINE™ compounds function by binding with and inhibiting the nuclear export protein XPO1 (or CRM1).
