Karyopharm’s Phase 2b SADAL Data Evaluating Selinexor in Diffuse Large B-Cell Lymphoma Selected for Oral Presentation at the 2017 European Hematology Association Annual Meeting

On May 18, 2017 Karyopharm Therapeutics Inc. (Nasdaq:KPTI), a clinical-stage pharmaceutical company, reported that interim clinical data from the ongoing Phase 2b SADAL study evaluating lead product candidate, selinexor (KPT-330), an oral Selective Inhibitor of Nuclear Export / SINE compound, in patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) will be featured in an oral presentation at the 22nd Congress of the European Hematology Association (EHA) (Free EHA Whitepaper) taking place June 22-25, 2017 in Madrid, Spain (Press release, Karyopharm, MAY 18, 2017, View Source [SID1234519226]).

"DLBCL is the most common type of non-Hodgkin lymphoma among adults and there remains a high unmet medical need, particularly in the relapsed and refractory setting for patients who are not eligible for stem cell transplant or who relapse afterward," said Sharon Shacham, PhD, MBA, President and Chief Scientific Officer of Karyopharm. "Previously reported data from the ongoing Phase 2b SADAL study showed that treatment with single-agent oral selinexor resulted in robust response rates with prolonged durability in patients with heavily pretreated DLBCL, including against both GCB and non-GCB (ABC) subtypes. We look forward to sharing some further detail from the SADAL study with the medical community at EHA (Free EHA Whitepaper) and ICML this year."

In addition, Karyopharm’s Phase 2b SADAL data were also selected for a poster presentation at the 14th International Conference on Malignant Lymphoma (ICML) being held June 14-17, 2017 in Lugano, Switzerland.

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 2,000 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 May 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. Additional clinical trial information for selinexor is available at www.clinicaltrials.gov.
