NEWTON, Mass., May 04, 2017 (GLOBE NEWSWIRE) -- Karyopharm Therapeutics Inc. (Nasdaq:KPTI), a clinical-stage pharmaceutical company, today reported financial results for the first 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).
"It's been a highly active early 2017 for Karyopharm, marked most notably by establishment of a planned approval path for selinexor in relapsed or refractory diffuse large B-cell lymphoma (DLBCL), our second lead indication after multiple myeloma (MM), following the presentation of robust interim data from the Phase 2b SADAL study at the American Association for Cancer Research (AACR) 2017 Annual Meeting," said Michael G. Kauffman, MD, PhD, Chief Executive Officer of Karyopharm. "After the observation of a 28.6% overall response rate (ORR) with over 7 months median duration of response (DOR), we consulted with the U.S. Food and Drug Administration (FDA) and obtained their agreement to amend the SADAL study to focus solely on the 60mg twice weekly treatment cohort, in which we plan to enroll up to 90 more patients. Assuming we continue to see the response rate and durability observed to date, we plan to use the data from the SADAL study to support a request for accelerated approval in DLBCL. Looking ahead, we remain focused on the initiation of the pivotal Phase 3 BOSTON study where we will evaluate selinexor in combination with Velcade® (bortezomib) and dexamethasone in patients with myeloma previously treated with one to three regimens, moving selinexor into much earlier lines of treatment."
Dr. Kauffman continued, "Importantly, during April 2017, we strengthened our balance sheet by raising net proceeds of approximately $52.2 million in equity financings, including approximately $37.8 million in an underwritten public offering and $14.5 million through our at-the-market (ATM) offering program. We plan to use these funds to support the continued clinical development of selinexor in our lead indications, including in multiple myeloma, DLBCL and other oncology indications, with a focus on filing for accelerated approvals for both myeloma and DLBCL during 2018. In addition, we expect this capital will fund our operations into 2019, while we are preparing to establish a commercial infrastructure for the potential launch of selinexor in North America and Western Europe."
First Quarter 2017 and Recent Events, Highlights and Milestones:
Selinexor in Multiple Myeloma (MM)
Selinexor in Diffuse Large B-Cell Lymphoma (DLBCL)
As a result of these findings, and in consultation with the FDA, Karyopharm is amending the SADAL study protocol to become a single-arm study focusing solely on single-agent selinexor dosed at 60mg twice weekly, eliminating the 100mg arm. The study is also being amended to reduce the 14-week treatment-free period to 8 weeks in patients who achieved at least a partial response (PR) on their most recent therapy. Patients whose disease was refractory or did not achieve at least a PR on their prior therapy will continue with the 14-week treatment-free period. The FDA agreed that the modification to a single-arm study was reasonable and that the proposed trial design and indication appear appropriate for accelerated approval, though eligibility for accelerated approval will depend on the complete trial results and available therapies at the time of regulatory action. The Company plans to enroll up to an additional 90 patients to the 60mg single-arm cohort and expects to report top-line results from the SADAL study in mid-2018.

First Quarter 2017 Financial Results
Cash, cash equivalents and investments as of March 31, 2017, including restricted cash, totaled $150.6 million, compared to $175.5 million as of December 31, 2016.
On April 28, 2017, Karyopharm completed an underwritten public offering of 3,902,439 shares of its common stock at a price to the public of $10.25 per share. The net proceeds to Karyopharm from the offering, after deducting the underwriting discounts and commissions and estimated offering expenses, were approximately $37.8 million. In addition, during April 2017, the Company completed the sale of approximately 1.3 million shares under the ATM offering facility for net proceeds of approximately $14.5 million.
For the quarter ended March 31, 2017, research and development expense was $24.1 million compared to $21.8 million for the quarter ended March 31, 2016. For the quarter ended March 31, 2017, general and administrative expense was $6.3 million compared to $5.6 million for the quarter ended March 31, 2016.
Karyopharm reported a net loss of $29.9 million, or $0.71 per share, for the quarter ended March 31, 2017, compared to a net loss of $27.1 million, or $0.75 per share, for the quarter ended March 31, 2016. Net loss includes stock-based compensation expense of $5.9 million and $5.2 million for the quarters ended March 31, 2017 and March 31, 2016, respectively.
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 $85 to 90 million. Based on current operating plans, Karyopharm expects that its existing cash and cash equivalents, along with the $52.2 million of net proceeds raised in April 2017, will be sufficient to fund its research and development programs and operations into 2019, including the continued clinical development of selinexor in our 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.

Karyopharm Therapeutics Inc. (Nasdaq:KPTI) is a clinical-stage pharmaceutical company focused on the discovery and development of novel first-in-class drugs directed against nuclear transport and related targets for the treatment of cancer and other major diseases. Karyopharm's SINE™ compounds function by binding with and inhibiting the nuclear export protein XPO1 (or CRM1). The Company's initial focus is on seeking regulatory approval and commercialization of its lead drug candidate, oral selinexor (KPT-330). 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 multiple myeloma in combination with low-dose dexamethasone (STORM) and backbone therapies (STOMP), 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. In addition to single-agent and combination activity against a variety of human cancers, SINE™ compounds have also shown biological activity in models of neurodegeneration, inflammation, autoimmune disease, certain viruses and wound-healing. Karyopharm, which was founded by Dr. Sharon Shacham, currently has five investigational programs in clinical or preclinical development. For more information, please visit www.karyopharm.com.
