Presentations Include Eleven Preclinical Abstracts Describing Key Scientific Findings across the Company’s Oncology Programs
Overview of Key Selinexor Myeloma Data Also Featured at the 16 th International Myeloma Workshop
NEWTON, Mass., March 01, 2017 (GLOBE NEWSWIRE) -- Karyopharm Therapeutics Inc. (Nasdaq: KPTI ), a clinical-stage pharmaceutical company, today announced that 12 abstracts describing the Company's product candidates in development for hematological and solid tumor malignancies have been selected for presentation at the 2017 Annual Meeting of the American Association for Cancer Research (AACR) taking place April 1-5, 2017 in Washington, DC. The abstracts, which represent both company- and investigator-sponsored studies, describe data related to Karyopharm’s lead product candidate, selinexor (KPT-330), an oral Selective Inhibitor of Nuclear Export / SINE™ compound, as well as two of its promising Phase 1 oncology programs, KPT-8602, a second-generation oral SINE compound, and KPT-9274, a first-in-class oral dual inhibitor of PAK4 and NAMPT.
“The ongoing randomized Phase 2b SADAL study, which was initiated based on encouraging Phase 1 data in patients with diffuse large B-cell lymphoma (DLBCL), was designed to evaluate the overall response rate of single-agent oral selinexor in patients with relapsed or refractory DLBCL,” said Sharon Shacham, PhD, MBA, President and Chief Scientific Officer of Karyopharm. “We look forward to presenting interim results from this important trial at AACR this year.”
Karyopharm is also presenting an overview of selinexor myeloma data at the 16 th International Myeloma Workshop (IMW) held March 1-4, 2017 in New Delhi, India. In an oral presentation, titled “Oral Selinexor Shows Single Agent Activity Enhanced with PI or IMiD Combinations in Refractory Multiple Myeloma,” (Abstract #234) Sagar Lonial, MD, FACP, Professor and Chair, Hematology and Medical Oncology, Emory University, provided an overview of clinical data demonstrating selinexor’s activity in combination with proteasome inhibitors (PIs) and immunomodulatory drugs (IMiDs) for the treatment of relapsed or refractory multiple myeloma. The 2017 IMW is a prestigious biannual event where myeloma experts from around the world gather to discuss basic, preclinical and clinical aspects in the biology and treatment of multiple myeloma.

About Selinexor
Selinexor (KPT-330) is a first-in-class, oral Selective Inhibitor of Nuclear Export / SINE™ compound. Selinexor functions by binding with and inhibiting the nuclear export protein XPO1 (also called CRM1), leading to the accumulation of tumor suppressor proteins in the cell nucleus. This reinitiates and amplifies their tumor suppressor function and is believed to lead to the selective induction of apoptosis in cancer cells, while largely sparing normal cells. To date, over 1,900 patients have been treated with selinexor and it is currently being evaluated in several mid- and later-phase clinical trials across multiple cancer indications, including in multiple myeloma in combination with low-dose dexamethasone (STORM) and backbone therapies (STOMP), and in diffuse large B-cell lymphoma (SADAL), and liposarcoma (SEAL), among others. Karyopharm plans to initiate a pivotal randomized Phase 3 study of selinexor in combination with bortezomib (Velcade ® ) and low-dose dexamethasone (BOSTON) in patients with multiple myeloma in early 2017. Additional Phase 1, Phase 2 and Phase 3 studies are ongoing or currently planned, including multiple studies in combination with one or more approved therapies in a variety of tumor types to further inform the Company's clinical development priorities for selinexor. The latest clinical trial information for selinexor is available at www.clinicaltrials.gov .
