NEWTON, Mass., March 14, 2016 (GLOBE NEWSWIRE) -- Karyopharm Therapeutics Inc. (Nasdaq:KPTI), a clinical-stage pharmaceutical company, today reported financial results for the fourth quarter and full year 2015 and commented on recent accomplishments and clinical development plans for its pipeline of several SINE-based therapeutics including selinexor, its lead product candidate.
"During 2015, we continued to expand our leadership position in the development of oral SINE-based oncology and non-oncology therapies with clinical advancement of selinexor across a number of hematologic and solid tumor indications and the presentation of encouraging data on our earlier-stage pipeline programs," said Michael G. Kauffman, MD, PhD, Chief Executive Officer of Karyopharm. "Our broad and aggressive oncology clinical development program continues in 2016 with both company- and investigator-sponsored trials underway or planned to evaluate selinexor both as a single-agent and in combination with other existing and emerging oncology therapies. In addition, we made important progress with our non-oncology focused SINE compounds in a number of disease areas in which XPO1 is critically involved. We look forward to several potentially value-creating data readouts over the next 18 months."

Clinical Development Plans:
- Selinexor in hematologic malignancies. Karyopharm is actively enrolling patients in several later phase clinical studies evaluating single-agent selinexor in hematologic malignancies, including patients with relapsed/refractory multiple myeloma (MM) (STORM study), older patients with relapsed/refractory acute myeloid leukemia (AML) (SOPRA study) and patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL) (SADAL study). Karyopharm expects data from the first 80 patients in the STORM study to be available in mid-2016, at which point, it will evaluate whether to expand the study. Karyopharm also expects to provide an interim analysis update from the SOPRA study in late-2016 with top-line data expected in mid-2017. Based on discussions with the U.S. Food and Drug Administration (FDA), Karyopharm amended the protocol for the ongoing SADAL study to remove dexamethasone from the regimen and to evaluate selinexor as a single-agent in this patient population. The study will continue to compare 60 mg and 100mg twice weekly doses of selinexor with 100 patients per arm and at least 50% of patients with GCB-type DLBCL. Based on these amendments, the company expects to report top-line data from this study in early 2017.
- Single-agent selinexor in solid tumors. Karyopharm is currently conducting company-sponsored trials of single-agent selinexor in three solid tumor indications including advanced unresectable dedifferentiated liposarcoma (SEAL study), heavily pretreated patients with gynecologic malignancies (SIGN study) and recurrent glioblastoma multiforme (KING study). Karyopharm is planning to present updated data from the SIGN and KING studies at an appropriate medical meeting in mid-2016. The Phase 2/3 SEAL study, evaluating single-agent oral selinexor versus placebo, was initiated earlier this year based on promising clinical data presented at the American Society of Clinical Oncology (ASCO) 2015 Annual Meeting in which durable stable disease and improvement in progression free survival compared to previous chemotherapies were observed. Top-line data from the Phase 2 portion of this study are expected in mid-2017.
- Selinexor combinations. A number of investigator-sponsored and company-sponsored trials evaluating selinexor in combination with either chemotherapy or targeted agents in hematologic and solid tumor indications are currently ongoing or planned. In mid-2016, Karyopharm plans to initiate a Phase 2/3 study (SCORE study) evaluating the combination of selinexor, carfilzomib and dexamethasone in patients with refractory MM who were previously treated with a proteasome inhibitor and an immunomodulatory agent. In addition, Karyopharm expects to report top line data from the Phase 1 portion of a Phase 1b/2 study (STOMP study) evaluating selinexor in combination with commonly used treatments, including bortezomib, pomalidomide, or lenalidomide, for relapsed/refractory MM in late-2016.
- KPT-8602, second generation SINE compound. In January 2016, Karyopharm initiated a Phase 1/2 study of oral KPT-8602, a novel, second generation, SINE compound, in patients with relapsed/refractory MM. Data from preclinical studies presented at the 2015 American Society of Hematology (ASH) Annual Meeting demonstrated single-agent anti-MM activity of KPT-8602 along with the potential for higher and/or more frequent dosing compared with selinexor. Top-line safety and tolerability data from this Phase 1/2 study are expected in late 2016.
- KPT-9274, oral dual inhibitor of PAK4 and NAMPT. In mid-2016, Karyopharm plans to initiate clinical development in patients with heavily pretreated solid tumors or lymphoma for its oral dual inhibitor of PAK4 and NAMPT, KPT-9274.
- Verdinexor (KPT-335). In May 2015, Karyopharm began clinical testing of verdinexor in a randomized, double-blind, placebo-controlled, dose-escalating Phase 1 clinical trial in healthy human volunteers in Australia. Verdinexor was found to be generally safe and well tolerated. Karyopharm is preparing to advance verdinexor for certain viral indications with an initial focus on influenza. Preclinical data provide strong support for other potential indications for verdinexor, including human immunodeficiency virus (HIV).
- KPT-350. KPT-350 is an investigational new drug application-ready oral compound with a preclinical data package supporting potential efficacy in a number of neurological, autoimmune and inflammatory conditions. We plan to partner with a collaborator to undertake the clinical development and potential commercialization of KPT-350 in one or more mutually agreed indications.
Scientific Presentations and Publications:
- Positive clinical data demonstrating the activity and tolerability of selinexor across multiple hematologic malignancies including MM and AML were presented at the 2015 American Society of Hematology (ASH) Annual Meeting held in December 2015 in Orlando, Florida.
- Updated data from an ongoing investigator-sponsored trial of selinexor in combination with carfilzomib and dexamethasone in refractory MM were presented by Andrzej Jakubowiak, MD, PhD, from The University of Chicago. The data demonstrated encouraging efficacy of selinexor in combination with carfilzomib and dexamethasone in heavily pretreated patients with highly refractory MM, including patients whose disease is refractory to previous carfilzomib-based combinations, suggesting the potential of this combination to overcome carfilzomib resistance. Based on these data, Karyopharm expects to initiate a Phase 2/3 clinical study (SCORE study) in mid-2016.
- Karyopharm researchers and collaborators also presented preclinical data demonstrating the potential of selinexor to synergize with proteasome inhibitors to overcome drug resistance in MM.
- Karyopharm presented data demonstrating the activity and tolerability of selinexor in combination with standard of care agents in the AML setting, including data from a Phase 2 trial investigating the efficacy and tolerability of selinexor in combination with arabinoside cytosine (Ara-C) and idarubicin in "fit" patients with relapsed and/or refractory AML. Karyopharm also presented data from a Phase 1 study determining the safety and efficacy of selinexor in combination with fludarabine and cytarabine in pediatric patients with relapsed and/or refractory acute leukemia.
- Karyopharm researchers presented data establishing 60mg as the most appropriate selinexor dose for both efficacy and tolerability across many hematologic and solid cancers. These data support the selinexor first-in-human Phase 1 clinical trial solid tumor data published in Journal of Clinical Oncology in March 2016, which recommended a dose of 60mg given twice a week as the Phase 2 dose. This recommendation was based on superior patient tolerability, longer duration of therapy, and no demonstrable improvement in radiologic response or disease stabilization compared with higher doses.
