NEWTON, Mass., Aug. 08, 2017 (GLOBE NEWSWIRE) -- Karyopharm Therapeutics Inc. (Nasdaq:KPTI), a clinical-stage pharmaceutical company, today reported financial results for the second quarter 2017 and commented on recent accomplishments and clinical development plans for its lead, novel, oral Selective Inhibitor of Nuclear Export (SINE™) compound selinexor (KPT-330), and other pipeline assets verdinexor (KPT-335), and KPT-9274, its oral, dual inhibitor of p21-activated kinase 4 (PAK4) and nicotinamide phosphoribosyltransferase (NAMPT).

"Our second quarter achievements marked significant progress across several of our development programs, and especially for selinexor," said Michael G. Kauffman, MD, PhD, Chief Executive Officer of Karyopharm.  "At the 2017 European Hematology Association (EHA) Annual Meeting, we reported updated data from the Phase 2b SADAL study investigating selinexor in patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL).  The overall response rate (ORR) increased to 33.3% for the overall trial population with similar response rates in patients with double- or triple-hit DLBCL, indicating clear activity in this population which usually has a particularly poor prognosis.  As we move to the second half of the year, our focus remains on execution of key later-stage trials in our lead indications of multiple myeloma (MM), DLBCL and liposarcoma.  In myeloma, the pivotal Phase 3 BOSTON study is now underway.  The Phase 2b STORM study, for possible accelerated approval, continues to enroll well with top-line data expected by April 2018.  In liposarcoma, the Phase 2 portion of the blinded, randomized Phase 2/3 SEAL study recently completed enrollment and we look forward to reporting the hazard ratio for progression-free survival (PFS) and providing an update regarding the planned development path in this indication during September or October 2017."

Second Quarter 2017 and Recent Events, Highlights and Milestones:

Selinexor in Multiple Myeloma

Selinexor in Diffuse Large B-Cell Lymphoma

Selinexor in Other Hematologic Malignancies

Published Phase 1 Data Demonstrating Selinexor's Activity in Patients with Relapsed/Refractory Non-Hodgkin's Lymphoma (NHL) in the Journal BloodA paper describing results from the first in human Phase 1 clinical study assessing safety and preliminary activity of selinexor in patients with relapsed or refractory NHL was recently published in the journal Blood.  In the paper, authored by John Kuruvilla, et al., titled "Selective inhibition of nuclear export with selinexor in patients with non-Hodgkin's lymphoma," Karyopharm collaborators reported that selinexor was generally well tolerated.  Of the 70 evaluable patients, 22 (31%) achieved an objective response (OR), including 4 CRs and 18 PRs, which were observed across a spectrum of NHL subtypes, including DLBCL, Richter's transformation, mantle cell lymphoma, follicular lymphoma and chronic lymphocytic leukemia. All four CRs were in patients with DLBCL, and two of the four patients are believed to have remained relapse-free as of the publication date, greater than 3 years since initiation of single agent selinexor therapy.  Tumor biopsies showed decreases in cell signaling pathways, reduced proliferation, nuclear localization of XPO1 cargos and increased apoptosis after treatment. The most common grade 3-4 drug-related AEs were thrombocytopenia (47%), neutropenia (32%), anemia (27%), leukopenia (16%), fatigue (11%) and hyponatremia (10%). A maximum tolerated dose was not defined, but the highest allowable dose was ~120 mg twice weekly.  Based on both tolerability and antitumor activity, the recommended Phase 2 dose of selinexor in NHL is 35 mg/m2 (~60 mg) twice weekly.

Second Quarter 2017 Financial Results

Cash, cash equivalents and investments as of June 30, 2017, including restricted cash, totaled $181.2 million, compared to $175.5 million as of December 31, 2016.

For the quarter ended June 30, 2017, research and development expense was $23.1 million compared to $24.6 million for the quarter ended June 30, 2016.  For the quarter ended June 30, 2017, general and administrative expense was $6.6 million compared to $6.0 million for the quarter ended June 30, 2016.

Karyopharm reported a net loss of $29.4 million, or $0.64 per share, for the quarter ended June 30, 2017, compared to a net loss of $30.2 million, or $0.84 per share, for the quarter ended June 30, 2016.  Net loss includes stock-based compensation expense of $5.1 million and $6.4 million for the quarters ended June 30, 2017 and June 30, 2016, respectively.

Financial Outlook

Karyopharm expects its operating cash burn, including research and development and general and administrative expenses, for the year ending December 31, 2017 to be in the range of $90-95 million.  Based on current operating plans, Karyopharm expects that its existing cash and cash equivalents will be sufficient to fund its research and development programs and operations into 2019, including the continued clinical development of selinexor in the Company's lead indications with a focus on filing for accelerated approvals for both MM and DLBCL during 2018, and preparing a commercial infrastructure for the potential launch of selinexor in North America and Western Europe.
