NEWTON, Mass., Nov. 07, 2016 (GLOBE NEWSWIRE) -- Karyopharm Therapeutics Inc. (Nasdaq:KPTI), a clinical-stage pharmaceutical company, today reported financial results for the third quarter 2016 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 KPT-8602, its second-generation SINE™ compound.
"During the third quarter, we communicated our planned development and regulatory approval path for oral selinexor as a treatment for patients with multiple myeloma (MM)," said Michael G. Kauffman, MD, PhD, Chief Executive Officer of Karyopharm. "We believe this plan, based on the positive selinexor-dexamethasone efficacy emerging from STORM and the selinexor-Velcade® (bortezomib)-dexamethasone combination data from STOMP, provides a path to FDA and EMA filings. At the upcoming American Society of Hematology (ASH) 2016 Annual Meeting, we will be highlighting twenty-one abstracts, including key presentations featuring maturing data from both STORM and STOMP, new clinical data in acute myeloid leukemia (AML), including selinexor in combination with chemotherapies in patients with newly diagnosed and relapsed/refractory AML, and preliminary data from a Phase 1 study of KPT-8602 in patients with relapsed/refractory MM."
Dr. Kauffman continued, "Looking ahead to the remainder of 2016, we are focused on executing the STORM trial expansion which will add approximately 120 additional patients with penta-refractory disease. We expect to report top-line data from this expanded cohort in early 2018, and, assuming a positive outcome, we intend to use this data to support accelerated approval for selinexor in MM. The trial design for the planned Phase 3 BOSTON study evaluating selinexor in combination with bortezomib and dexamethasone in patients with MM previously treated with one to three regimens moves selinexor into much earlier lines of therapy and is currently being finalized to include feedback from the FDA. We remain on track to commence this pivotal study in early 2017."

Third Quarter 2016 and Recent Highlights:
Selinexor in Multiple Myeloma
- Reporting updated STORM data at ASH 2016. Karyopharm is scheduled to present updated clinical data from the ongoing Phase 2b STORM study at the upcoming ASH 2016 annual meeting in early December. In an oral presentation titled, "Selinexor and Low Dose Dexamethasone in Patients with Lenalidomide, Pomalidomide, Bortezomib, Carfilzomib and Anti-CD38 Ab Refractory MM STORM Study," Dan T. Vogl, MD, MSCE, Assistant Professor of Medicine, Perelman School of Medicine, University of Pennsylvania, will present data demonstrating that selinexor in combination with low-dose dexamethasone achieved an overall response rate (ORR) of 21% across all evaluable patients in the study. The ORRs were 21% in patients with quad-refractory disease and 20% in patients with penta-refractory disease, all based on Independent Review Committee (IRC) adjudication. The side effect profile for selinexor was consistent with previous trials, with low rates of Grade ≥3 non-hematologic toxicity, Grade ≥4 infections (1.3%) and sepsis (1.3%). Patients with quad-refractory disease have documentation that they have previously received two PIs (bortezomib (Velcade) and carfilzomib (Kyprolis®)) and two IMiDs (lenalidomide (Revlimid®) and pomalidomide (Pomalyst®)), and their disease is refractory to at least one PI, at least one IMiD, alkylating agents and glucocorticoids, and has progressed following their most recent therapy. Patients with penta-refractory myeloma have quad-refractory disease that is also refractory to an anti-CD38 monoclonal antibody, such as daratumumab (Darzalex™) or isatuximab.
- Expanding STORM Study to Include 120 Additional Patients with Penta-refractory MM. The Company believes that there are currently no available therapies with known activity in patients with penta-refractory myeloma, and that this represents a growing unmet medical need. Therefore, Karyopharm has expanded the STORM study to include approximately 120 additional patients with penta-refractory MM and expects to report top-line data from the expanded cohort in early 2018. Assuming a positive outcome, Karyopharm intends to use the data from the expanded STORM study to support accelerated approval for selinexor in MM.
- Reporting Updated STOMP data at ASH 2016. Karyopharm is also scheduled to present updated clinical data from the ongoing Phase 1b STOMP study at ASH 2016. In an oral presentation titled, "Selinexor in Combination with Bortezomib and Dexamethasone Demonstrates Significant Activity in Patients with Refractory MM Including Proteasome-Inhibitor Refractory Patients," Nizar Bahlis, MD, Assistant Professor of Hematology, Southern Alberta Cancer Research Institute, will present data demonstrating that selinexor in combination with Velcade (bortezomib) and dexamethasone (SVd) achieved an ORR of 77% across all evaluable patients in the study. All 10 patients with non-refractory disease responded (5 patients with a very good partial response (VGPR) and 5 patients with a partial response (PR)) for an ORR of 100%. Twelve of the 22 patients in the SVd combination arm had MM previously refractory to a proteasome inhibitor, typically bortezomib or carfilzomib. Seven of these 12 patients responded (1 complete response and 6 PRs) for an ORR of 58%. Only one patient (4.5%) had progressive disease, suggesting that this regimen induces rapid and potent myeloma control, even amongst patients with MM that is refractory to one or more proteasome inhibitors. Side effects were generally less than those observed with the individual drugs, and only one case of neuropathy (Grade 1, 4.5%) was reported. Similar high levels of activity are observed with the combination of selinexor and carfilzomib with dexamethasone, including in patients with MM that is refractory to one or more proteasome inhibitors; results from the Phase 1/2 study of this combination will also be reported at ASH. Together, these data indicate that treatment with selinexor in combination with proteasome inhibitors leads to high levels of anti-MM activity, including in patients with proteasome-inhibitor refractory disease.
- Initiating Pivotal Phase 3 BOSTON Study in Early 2017. Based on the robust data from the SVd arm of the STOMP study, Karyopharm plans to initiate a pivotal randomized Phase 3 study, known as the BOSTON (Bortezomib, Selinexor and dexamethasone) study, which will evaluate SVd compared to bortezomib and low-dose dexamethasone (Vd) in patients with MM who have had one to three prior lines of therapy. Karyopharm has identified the combination dose of selinexor (100mg weekly), bortezomib (1.3 mg/m2 weekly given sub-cutaneously for 4 of 5 weeks) and dexamethasone (40mg weekly) to be used in the BOSTON study and expects that the study will enroll approximately 360 patients. Based on feedback from the FDA, the protocol is currently being finalized and the Company remains on track to commence the BOSTON study in early 2017.
- Karyopharm to Host Dinner Reception and Webcast at ASH 2016 Focusing on Multiple Myeloma. On Monday, December 5, 2016, Karyopharm will host an investor and analyst dinner reception, which will feature a moderated panel discussion with recognized thought leaders in the treatment of MM, updated selinexor data in MM, and a live Q&A session. The event will take place during the ASH 2016 annual meeting and interested parties can access a live webcast of the event beginning December 5, 2016 at 8:15 p.m. PT by going to the "Investors" section of the company's website at http://investors.karyopharm.com/events.cfm.
Selinexor in Acute Myeloid Leukemia (AML)
- Reporting Clinical Data from Phase 2 SAIL Study at ASH 2016. Updated clinical data from the Phase 2 SAIL study evaluating selinexor in combination with Ara-C and idarubicin in heavily pretreated patients with relapsed or refractory AML will be highlighted in an oral presentation by Walter Fiedler, MD, University Medical Center Hamburg. The SAIL data demonstrate that the selinexor, Ara-C and idarubicin combination achieved compelling response rates and has the potential to be an effective AML treatment option and serve as a bridge to stem cell transplantation in this patient population.
- Other Selinexor Combination Studies Selected for Oral and Poster Presentations at ASH 2016. Three additional abstracts were selected for presentation at ASH, including one oral presentation highlighting data from a clinical trial evaluating the combination of selinexor with high-dose cytarabine and mitoxantrone in patients with AML (Amy Wang, University of Chicago) and two poster presentations (Bhavana Bhatnagar, Ohio State University and Kendra Sweet, Moffitt Cancer Center). These presentations highlight early-stage clinical data demonstrating the feasibility and tolerability of selinexor in combination with other standard of care agents in patients with AML, including in elderly patients, as well as early signs of clinical activity, including response rates that are superior to published data using standard chemotherapy regimens.
Selinexor in Solid Tumors
- Reported Updated SIGN data at ESMO 2016. Updated clinical data from the Phase 2 SIGN study evaluating selinexor for the treatment of gynecological cancers were presented at the European Society of Medical Oncology (ESMO) 2016 annual meeting. In this study, single-agent selinexor demonstrated robust clinical benefit and favorable tolerability in patients with heavily pretreated gynecologic cancers, including a 49% disease control rate (DCR = PR plus stable disease for ≥3 months) in ovarian cancer and 45% in endometrial cancer. Selinexor-associated adverse events were found to be manageable with supportive care and dose modifications as demonstrated by the number of patients who have remained on study after achieving disease control, with some continuing treatment for longer than 12 months.
- Reporting Phase 1 KPT-8602 Clinical Data at ASH 2016. Clinical data from a Phase 1/2 study evaluating KPT-8602, Karyopharm's second-generation SINE™ compound, will be presented at ASH 2016 by Frank Cornell, MD, Vanderbilt Ingram Cancer Center. These data demonstrate that oral KPT-8602 is well tolerated in heavily pretreated patients with relapsed or refractory MM and shows early signs of encouraging efficacy.
