  Content	Karyopharm Announces Preliminary Unaudited 2024 Revenue and 2025 Objectives PR Newswire Mon, Jan 13, 2025, 5:30 AM 18 min read In This Article: KPTI -6.37% – Opportunity to Define a New Myelofibrosis Treatment Paradigm with Top-Line Data Readout from Phase 3 SENTRY Trial Evaluating Selinexor in Combination with Ruxolitinib in Patients with JAKi-Naïve Myelofibrosis Anticipated in 2H 2025; Company On Track to Complete Enrollment in 1H 2025 – – Recently Announced Key Leadership Changes, including the Appointment of Lori Macomber as Chief Financial Officer and Brendan Strong as SVP of Investor Relations and Corporate Communications – – Preliminary Unaudited Full Year 2024 Total Revenue and U.S. XPOVIO ® (selinexor) Net Product Revenue Expected to be Approximately $145 Million and $113 Million , Respectively – NEWTON, Mass. , Jan. 13, 2025 /PRNewswire/ -- Karyopharm Therapeutics Inc. (Nasdaq: KPTI), a commercial-stage pharmaceutical company pioneering novel cancer therapies, today announced preliminary unaudited fourth quarter and full year 2024 total revenue and U.S. XPOVIO net product revenue estimates and outlined its 2024 achievements and 2025 objectives. "Our top strategic objective for 2025 is to deliver on the transformative opportunity to redefine the standard of care in myelofibrosis, with top-line results from our Phase 3 SENTRY trial on-track for the second half of this year.  Our teams are focused on high-quality clinical trial execution, engaging with investigators and diligently completing enrollment in the first half of this year," said Richard Paulson, President and Chief Executive Officer of Karyopharm. "We are excited by the potential for selinexor to be the first all-oral combination therapy in myelofibrosis and the benefit it may bring to this community. We look forward to reporting our top-line data and are preparing for a rapid launch, leveraging our demonstrated commercialization capabilities." Key Program Highlights in 2024 Selinexor in Multiple Myeloma (MM) Demand for XPOVIO was consistent in 2024 versus 2023, with demand growth in the second half of 2024 in both the community setting, which represents approximately 60% of XPOVIO net product revenue, and the academic setting, offsetting a decline in demand in the first half of the year due to an intensified competitive landscape. XPOVIO net product revenue was impacted year-over-year by higher gross-to-net adjustments in 2024, driven primarily by increased 340B discounts and Medicare rebates. Expanded global patient access for selinexor in 2024 with favorable reimbursement decisions in the United Kingdom , France , Italy , China and South Korea and additional regulatory approvals in UAE, Kuwait , China , Malaysia , Turkey , Thailand , and South Korea in various indications, increasing the number of countries where selinexor is now approved to more than 45 countries. Updated clinical data on selinexor in combination with pomalidomide and dexamethasone (SPd) regimen from the Phase 2 STOMP (NCT02343042) and the Phase 2 XPORT-MM-028 (NCT04414475) trials were published in the Frontiers of Oncology Journal in May 2024. Both trials are evaluating multiple selinexor combinations, including SPd, in patients with relapsed or refractory multiple myeloma. The updated results for SPd 40 mg from these studies showed a median progression free survival of 18.4 months and a manageable safety profile with no new safety signals identified. Completed enrollment of the Phase 3 XPORT-MM-031 trial (EMN29; NCT05028348) of approximately 120 patients, leveraging the data published on selinexor 40 mg, pomalidomide and dexamethasone (SPd40) in 2024. The Phase 3 XPORT-MM-031 trial is being conducted in collaboration with the European Myeloma Network and is evaluating the all-oral combination SPd40 in patients with previously treated multiple myeloma who received an anti-CD38 in their immediate prior line of therapy.  Pending ongoing engagement with regulatory agencies on the updated protocol and statistical plan, the Company intends to provide an update on this trial. Presented preclinical, translational, and real-world evidence data at multiple scientific conferences evaluating the role of XPO1 inhibition and selinexor in T-cell fitness. Story Continues Selinexor in Myelofibrosis (MF) Updated the co-primary endpoint on the Phase 3 SENTRY trial (XPORT-MF-034; NCT04562389) to absolute mean change in total symptom score (Abs-TSS) following alignment with the U.S. Food and Drug Administration (FDA) and proactively increased the total sample size to approximately 350 patients to further increase the statistical powering. Abs-TSS measures the average improvement in symptom scores over 24 weeks relative to the baseline symptom score. Abs-TSS is viewed by many key opinion leaders (KOLs) and patient advocacy organizations as a more accurate assessment of symptom improvement in head-to-head clinical trials, such as SENTRY which is evaluating selinexor in combination with ruxolitinib in patients with JAK inhibitor (JAKi) naïve myelofibrosis versus ruxolitinib alone. Spleen volume reduction ≥35% (SVR35) at week 24 remains the other co-primary endpoint. These two co-primary endpoints will be tested sequentially starting with SVR35 followed by Abs-TSS. Hosted an investor event with leading KOLs in October 2024 to discuss the change in the co-primary endpoint in the Phase 3 SENTRY trial to Abs-TSS and highlight the strength of the data from the Company's Phase 1 trial in myelofibrosis. Data from the Company's Phase 1 trial, evaluating the combination of selinexor 60 mg plus ruxolitinib in JAKi naïve myelofibrosis patients, demonstrated that 79% of patients in the intent to treat population (n=14) achieved SVR35 and an average Abs-TSS improvement of 18.5 points in the efficacy evaluable population (n=9), at week 24 relative to baseline. Acknowledging the small sample size, these data suggest that the combination is favorable compared to historical ruxolitinib monotherapy data which indicates that less than half of patients achieve SVR35 and an Abs-TSS improvement of 11 to 14 points 1 . As of the most recent data cut off, the safety profile remained consistent and no new safety signals were identified. Presented pre-clinical data at the June 2024 European Hematology Association Meeting which support selinexor's potential mechanism of action targeting multiple oncogenic pathways beyond JAK/STAT.  This data builds on the compelling clinical data on selinexor in myelofibrosis. 1 Phase 3 MANIFEST trial. Rampal R, et al. ASH 2023. Oral 628; Phase 3 TRANSFORM-1 trial Pemmaraju N, et al. ASH 2023 abstract 620. Selinexor in Endometrial Cancer (EC) The Company remains engaged with the FDA regarding the evolving treatment landscape in endometrial cancer and any implications this may have with respect to the Company's Phase 3 XPORT-EC-042 trial (NCT05611931). The Company intends to provide an update on its endometrial cancer program in the first quarter of 2025. Other Pipeline Assets KPT-9274 (padnarsertib), a first-in-class, oral small molecule and a dual inhibitor of PAK4 and NAMPT that was discovered at Karyopharm, was granted two Rare Pediatric Disease Designations by the FDA for the treatment of Rhabdomyosarcoma (RMS) and for the treatment of Ewing sarcoma (EWS) in June 2024. The FDA further granted KPT-9274 two Orphan Drug Designations in July 2024 for the treatment of soft tissue sarcoma, which includes RMS, and for the treatment of EWS. RMS and EWS are rare cancers of the bone or soft tissue, primarily diagnosed in pediatric patients, with poor survival outcomes and high unmet need for new therapies. KPT-9274 showed tumor regressions and decreased metastatic properties in pediatric RMS and EWS pre-clinical models. Karyopharm is evaluating out-licensing and/or partnership opportunities for further advancement of this program. In February 2024 , the Company reacquired KPT-350 and other assets, which had been sold to Biogen Inc. in January 2018 under an asset purchase agreement. KPT-350 is a clinical stage SINE compound under evaluation for neurological indications, including amyotrophic lateral sclerosis. Karyopharm intends to evaluate KPT-350 for development through a third-party. Corporate and Financial Highlights for 2024 Based on preliminary unaudited financial information, the Company expects total revenue, which includes license and royalty revenue from partners, to be approximately $30 million for the fourth quarter 2024 and approximately $145 million for the full year 2024, and U.S. XPOVIO net product revenue to be approximately $29 million for the fourth quarter 2024 and approximately $113 million for the full year 2024. Completed significant refinancing transactions and amended royalty agreement with HealthCare Royalty extending the vast majority of the Company's debt maturities into 2028 and 2029. Expect to deliver meaningful reductions in selling, general and administrative expense in 2024 as the Company focused its resources on research and development initiatives and overall cost optimization opportunities. Announced the appointment of Lori Macomber as Executive Vice President, Chief Financial Officer and Treasurer, effective January 3, 2025. Announced the appointment of Brendan Strong as Senior Vice President of Investor Relations and Corporate Communications, effective December 9, 2024 . Cash, cash equivalents, restricted cash and investments as of December 31, 2024 was approximately $109 million. The Company expects that its existing cash, cash equivalents and investments, the revenue it expects to generate from XPOVIO net product sales and its license agreements and ongoing disciplined expense management and cost saving measures, will be sufficient to fund its planned operations into the first quarter of 2026. 2 2 Excluding re-payment of $24.5 million aggregate principal amount of the Company's remaining senior convertible notes due October 2025 (the 2025 Notes) and $25.0 million minimum liquidity covenant under the Company's senior secured term loan due 2028. Taking into account the repayment of the 2025 Notes and the minimum liquidity covenant, Karyopharm expects its cash, cash equivalents and investments will be sufficient to fund its operations into the fourth quarter of 2025. The financial information presented in this press release may be adjusted as a result of the completion of customary annual review and audit procedures.

Corporate Presentation Karyopharm will be posting an updated corporate overview presentation on its website today. The presentation will be accessible under "Events & Presentations" in the Investor section of the Company's website, http://investors.karyopharm.com/events-presentations . About the Phase 3 SENTRY Trial SENTRY (NCT04562389) is a pivotal, Phase 3 clinical trial evaluating a once-weekly dose of 60 mg of selinexor in combination with twice-daily ruxolitinib versus placebo plus ruxolitinib in JAKi naïve patients with platelet counts > 100 x 10 9 /L. Karyopharm intends to enroll approximately 350 JAKi naïve patients with myelofibrosis in this Phase 3 trial; patients are randomized 2:1 to the selinexor arm. The co-primary endpoints will be spleen volume response rate ≥ 35% (SVR35) at week 24 and the absolute mean change in total symptom score (Abs-TSS) over 24 weeks relative to baseline. About the Phase 3 XPORT-EC-042 Study XPORT-EC-042 (NCT05611931) is a global, Phase 3, randomized, double-blind study evaluating selinexor as a maintenance therapy following systemic therapy in patients with TP53 wild-type advanced or recurrent endometrial cancer. The EC-042 study was initiated in November 2022 and is expected to enroll up to 220 patients who will be randomized 1:1 to receive either a 60 mg, once-weekly, administration of oral selinexor or placebo until disease progression. The primary endpoint of the study is progression free survival, as assessed by an investigator, with overall survival as a key secondary endpoint. Further, in connection with the EC-042 Study, Karyopharm entered into a global collaboration with Foundation Medicine, Inc. to develop FoundationOne ® CDx, a tissue-based comprehensive genomic profiling test to identify and enroll patients whose tumors are TP53 wild-type.
