NEWTON, Mass., Feb. 13, 2020 (GLOBE NEWSWIRE) -- Karyopharm Therapeutics Inc. (Nasdaq:KPTI), an oncology-focused pharmaceutical company, today reported financial results for the fourth quarter and full year ended December 31, 2019. In addition, Karyopharm highlighted select corporate milestones, including details regarding the ongoing U.S. commercial launch of XPOVIO® (selinexor), and provided an overview of its key clinical development programs.

“2019 was a year of significant progress for Karyopharm as we successfully transitioned into an integrated commercial organization following the accelerated approval of oral XPOVIO, the first and only nuclear export inhibitor approved in the U.S., indicated for patients with heavily pretreated multiple myeloma. Our XPOVIO commercial launch efforts have yielded a strong positive reception from prescribing physicians and patients, with approximately 1,400 prescriptions filled in 2019,” said Michael G. Kauffman, MD, PhD, Chief Executive Officer of Karyopharm. “Our pipeline efforts also continued to advance with the top-line Phase 3 BOSTON study results expected before the end of April, which if positive, could support future regulatory submissions and dramatically increase the eligible multiple myeloma patient population for XPOVIO. And importantly, we ended the year with the submission of our supplemental New Drug Application (sNDA) in the U.S. based on our SADAL study for selinexor requesting accelerated approval for patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL), a disease with significant patient unmet need.”

Fourth Quarter 2019 Highlights and Recent Progress

XPOVIO (selinexor) in Multiple Myeloma

  • XPOVIO U.S. Commercial Launch Continues Momentum. Oral XPOVIO became commercially available to patients in the U.S on July 9, 2019 and generated net product sales of $17.7 million in the fourth quarter and $30.5 million for the full year 2019. As of December 31, 2019, approximately 1,400 XPOVIO prescriptions have been filled, driven by strong demand from both academic and community-based oncologists. XPOVIO has been prescribed by more than 550 unique physicians and healthcare accounts. Net product sales increased by approximately 38% in the fourth quarter of 2019 as compared to the third quarter of 2019 with prescription demand (defined as prescriptions shipped from Karyopharm’s distribution partners to individual patients and prescribing healthcare accounts) increasing by approximately 65% in the fourth quarter as compared to the third quarter of 2019.   

    Increased fourth quarter net revenues were primarily driven by a combination of new patient starts and prescription refills. Broad insurance coverage for XPOVIO has been a key contributor to its commercial success with XPOVIO being added to numerous national commercial and Medicare formularies and coverage policies. Based on prescription fulfillment data through the specialty pharmacy channel, Karyopharm estimates that approximately 55% of XPOVIO prescriptions have been dispensed to patients with Medicare coverage, 40% to patients with commercial insurance, and the remaining patients having either Medicaid or another form of prescription coverage.

  • 22 Abstracts Presented at the American Society of Hematology (ASH) 2019 Annual Meeting. Multiple data presentations highlighting selinexor at the ASH 2019 Annual Meeting held December 7-10, 2019, continue to reinforce the potential clinical utility of selinexor as a new therapeutic option for patients with relapsed or refractory multiple myeloma. This included one oral presentation which provided updated data from the Phase 1b/2 STOMP study evaluating the all oral regimen of selinexor in combination with Pomalyst® (pomalidomide) and low-dose dexamethasone (dex) (SPd) in patients with relapsed or refractory multiple myeloma. Patients with Pomalyst-naïve and Revlimid® (lenalidomide)-relapsed or -refractory myeloma achieved a 56% overall response rate (ORR) and a 12.2-month progression free survival (PFS) on the SPd regimen. A separate poster presentation detailed results for the Kyprolis® (carfilzomib) arm of the Phase 1b/2 STOMP study which showed a 71% ORR and a 21% complete response rate (CR) in patients with heavily pretreated Kyprolis-naïve multiple myeloma. New data from patients treated with selinexor-based regimens after their myeloma had progressed following experimental CAR-T (chimeric antigen receptor modified T cell)  therapy was also highlighted in a poster and demonstrated promising early responses from six of seven patients, reinforcing the potential therapeutic activity of selinexor in patients with advanced refractory disease.

  • Decision from European Medicines Agency (EMA) for Marketing Authorization Application (MAA) Now Expected in Mid-2020.  In January 2019, Karyopharm submitted an MAA to the EMA requesting conditional approval for selinexor, in combination with dexamethasone, as a new treatment for patients with heavily pretreated multiple myeloma based on the results of the Phase 2b STORM study. In January 2020, Karyopharm was granted a three-month extension from the EMA’s Committee for Medicinal Products for Human Use to provide additional time to respond to the outstanding questions related to the MAA. The Company now expects a decision on the selinexor MAA in mid-2020.

  • Pivotal Phase 3 BOSTON Study Remains On Track. Top-line data are expected before the end of April 2020 contingent upon the occurrence of PFS events, the primary endpoint of the study. The BOSTON study is evaluating 100mg of selinexor dosed once weekly in combination with the proteasome inhibitor Velcade® (bortezomib) (once weekly) and low dose dexamethasone (SVd), compared to standard twice weekly Velcade and low dose dexamethasone (Vd) in patients with multiple myeloma who have had one to three prior lines of therapy. Data from the BOSTON study, if positive, are expected to be used to support regulatory submissions to the U.S. Food and Drug Administration (FDA) and EMA requesting the use of selinexor in combination with Velcade and dexamethasone in patients with multiple myeloma who have received at least one prior therapy.

Selinexor in Diffuse Large B-Cell Lymphoma (DLBCL)

  • sNDA Submitted in December 2019. Following the positive results from the Phase 2b SADAL study that were first presented at the ASH 2018 Annual Meeting and then updated in June 2019 at the 2019 International Conference on Malignant Lymphoma, Karyopharm submitted a sNDA to the FDA in December 2019 requesting accelerated approval for selinexor as a treatment for patients with relapsed or refractory DLBCL after at least two prior multi-agent therapies and who are ineligible for stem cell transplantation including CAR-T therapy. The Company also expects to submit an MAA to the EMA in 2020 requesting conditional approval for selinexor in the same indication. In addition to orphan drug designation, selinexor was granted fast track designation for this indication by the FDA in 2018.

Selinexor in Solid Tumors

  • Ongoing Phase 3 Portion of the Phase 2/3 SEAL Study in Liposarcoma.  Karyopharm previously reported positive results from the Phase 2 portion of the randomized, blinded Phase 2/3 SEAL study evaluating single-agent selinexor versus placebo in patients with previously treated, advanced unresectable dedifferentiated liposarcoma.  Enrollment is currently ongoing in the Phase 3 portion of the SEAL study.  Top-line data from the Phase 3 portion of the SEAL study are anticipated in 2020. Assuming a positive outcome on the primary endpoint of PFS, the Company intends to use the data from the SEAL study to support NDA and MAA submissions requesting approval for selinexor for patients with advanced unresectable dedifferentiated liposarcoma.

Other Pipeline Updates

  • Five New Clinical Trials Expected to Start in 2020 to Investigate Karyopharm Drug Candidates Across Both Hematologic Malignancies and Solid Tumors:
     
    • DLBCL:  XPORT-DLBCL-030 is a Phase 2/3 trial expected to serve as a confirmatory study for the accelerated approval requested in DLBCL based on the SADAL study. This trial will study selinexor or a matching placebo given with the standard combination immunochemotherapy R-GDP (rituximab, gemcitabine, dexamethasone, cisplatin) to patients with at least one prior therapy and ineligible for high dose chemotherapy and stem cell transplantation (or CAR-T).  The primary endpoint of the study is PFS.
       
    • DLBCL: XPORT-DLBCL-025 is a multi-arm Phase 1/2 trial of selinexor in combination with commonly used and approved agents for the treatment of DLBCL.  This study will inform the clinical development of selinexor with a variety of additional agents for the treatment of DLBCL.
       
    • Colorectal Cancer and Lung Cancer: XPORT-STP-027 is a Phase 1/2 trial designed to study selinexor in combination with pembrolizumab in colorectal cancer and separately in combination with docetaxel in non-small cell lung cancer.
       
    • Glioblastoma (GBM): XPORT-GBM-029 is a Phase 1/2 trial designed to study selinexor in combination with active anti-cancer agents in both newly diagnosed and patients with recurrent disease.
       
    • Myelodysplastic Syndromes (MDS): Based on positive data from an ongoing Phase 1 / 2 trial of single-agent eltanexor presented at ASH 2019, we plan to evaluate the combination of eltanexor with cedazuridine-decitabine (ASTX727) in patients with newly diagnosed MDS. 
       
  • Encouraging Pre-Clinical Data Highlighting Potential Role of KPT-9274 Published in Nature CancerIn January 2020, results from a study conducted by researchers at the University of California, Los Angeles (UCLA) Jonsson Comprehensive Cancer Center were published in Nature Cancer. Researchers concluded that  inhibiting the kinase PAK4 improves the effectiveness of PD-1 blockade immunotherapy in melanoma cells. KPT-9274, Karyopharm’s investigational dual PAK4 and NAMPT inhibitor, was given in an animal model of melanoma in combination with anti-PD-1 immunotherapy, effectively slowing the growth of melanomas more than either drug alone. Finding novel molecular targets that could improve and overcome resistance to PD-1 blockade therapy remains a key priority in current cancer research and the results from this study support future clinical development of KPT-9274 in combination with anti-PD-1 therapy.

Corporate and Financial Updates

  • Executed Licensing Agreement with Neopharm Group to Commercialize XPOVIO in Israel.  In February 2020, Karyopharm and Promedico, a fully-owned Neopharm LTD company, entered into an exclusive distribution agreement for the commercialization of XPOVIO in Israel and the Palestinian Authority. Karyopharm will receive certain prespecified payments and is eligible to receive additional payments if prespecified regulatory and commercial milestones are achieved by Promedico. Karyopharm is also eligible to receive double-digit royalties on future net sales in the territory. Promedico is responsible for all regulatory filings and obligations required for registering XPOVIO. Karyopharm has retained exclusive production rights and will supply finished product for commercial use in the territory.

Full Year and Fourth Quarter 2019 Financial Results

Net product revenue: Net product revenue for the fourth quarter of 2019 was $17.7 million and $30.5 million for the year ended December 31, 2019. Karyopharm did not have net product revenue during the year ended December 31, 2018.

License and other revenue: License and other revenue for the fourth quarter of 2019 was $0.4 million, compared to $0.2 million for the fourth quarter of 2018. License and other revenue for the year ended 2019 was $10.4 million, compared to $30.3 million for the year ended 2018.

Cost of sales: Karyopharm began U.S. sales of XPOVIO in the third quarter of 2019. Cost of sales were $1.4 million for the fourth quarter of 2019, and $2.4 million for the year ended December 31, 2019. Cost of sales reflects the costs of XPOVIO units sold and third-party royalties on net product revenue.

Research and development expenses: Research and development expense for the fourth quarter of 2019 was $31.6 million, compared to $38.9 million for the fourth quarter of 2018. Research and development expense for the year ended 2019 was $122.3 million, compared to $161.4 million for the year ended 2018.

Selling, general and administrative expenses: For the fourth quarter 2019, selling, general and administrative expense was $28.4 million, compared to $18.8 million for the fourth quarter 2018. For the year ended December 31, 2019, selling, general and administrative expense was $105.4 million, compared to $48.8 million for the year ended December 31, 2018. The increase in selling, general and administrative expenses compared to the prior year was due primarily to the hiring of the Karyopharm commercial team and related activities to support the U.S. commercial launch of XPOVIO.

Interest expense: Interest expense for the fourth quarter and for the year ended December 31, 2019 was $6.5 million and $15.6 million, respectively, compared to $2.5 million for both the fourth quarter 2018 and the year ended December 31, 2018. The increase in interest expense is attributable to the imputed interest on the deferred royalty obligation Karyopharm has with HealthCare Royalty Partners (HCR).

Net loss: Karyopharm reported a net loss of $48.6 million, or $0.76 per share, for the fourth quarter 2019, compared to a net loss of $58.2 million, or $0.96 per share, for the fourth quarter 2018. Net loss includes non-cash stock-based compensation expense of $3.6 million and $3.9 million for the 2019 and 2018 quarters, respectively. Karyopharm reported a net loss of $199.6 million, or $3.22 per share, for the year ended 2019, compared to a net loss of $178.4 million, or $3.14 per share, for the year ended 2018. Net loss includes non-cash stock-based compensation expense of $15.3 million and $17.3 million for the years ended 2019 and 2018, respectively.

Cash position: Cash, cash equivalents, restricted cash and investments as of December 31, 2019 totaled $265.8 million, compared to $330.9 million as of December 31, 2018.

2020 Financial Outlook

Based on its current operating plans, Karyopharm expects its non-GAAP R&D and SG&A expenses, which excludes stock-based compensation expense, for the full year 2020 to be in the range of $240 million to $260 million.

The Company expects that its existing cash, cash equivalents and investments, and the revenue it expects to generate from XPOVIO product sales, will be sufficient to fund its planned operations into the middle of 2021.

Non-GAAP Financial Information

Karyopharm uses a non-GAAP financial measure, non-GAAP operating expense, to provide operating expense guidance. Non-GAAP operating expense excludes stock-based compensation expense. Karyopharm believes this non-GAAP financial measure is useful to investors because it provides greater transparency regarding Karyopharm’s operating performance as it excludes non-cash stock compensation expense. Karyopharm has not reconciled the full year 2020 outlook for non-GAAP operating expenses to full year 2020 outlook for GAAP operating expenses because Karyopharm cannot reliably predict without unreasonable efforts the timing or amount of the factors that substantially contribute to the projection of stock compensation expense, which is excluded from the full year 2020 outlook for non-GAAP operating expenses. This non-GAAP financial measure should not be considered a substitute or an alternative to GAAP total operating expense and should not be considered a measure of Karyopharm’s liquidity. Instead, non-GAAP operating expense should only be used to supplement an understanding of Karyopharm’s operating results as reported under GAAP.
