(Nasdaq: KPTI), a commercial-stage pharmaceutical company pioneering novel cancer therapies, today reported financial results for the fourth quarter and full year ended December 31, 2023. In addition, Karyopharm highlighted select corporate milestones and provided an overview of its key clinical development programs. "We made significant progress in 2023 across our clinical pipeline and continued to build on our foundation in the highly competitive multiple myeloma space. The encouraging clinical results that we presented last year reinforce the potential of our three ongoing pivotal Phase 3 trials in addressing critical unmet needs of cancer patients," said Richard Paulson, President and Chief Executive Officer of Karyopharm. "Our drive for innovation and progress will continue into 2024, by focusing our resources to advance our Phase 3 trials. We are enthusiastic about the upcoming top-line read-outs from these trials and what they could mean for patients and selinexor's growth potential." Fourth Quarter 2023 and Recent Highlights Research and Development (R&D) Highlights Long-term exploratory analysis of the pre-specified subgroup of patients with advanced or recurrent TP53 wild-type endometrial cancer (EC) from the Phase 3 SIENDO trial (NCT03555422) was presented at the International Gynecological Cancer Society Annual Global Meeting in Seoul, South Korea, with updated progression-free survival (PFS). As of the September 1, 2023 data cut-off date, median PFS was 27.4 months in the selinexor treatment arm (n=77) as compared to 5.2 months (n=36) in the placebo arm. Immature overall survival data showed an encouraging signal and corroborated the PFS results. Oral presentation at the 65th American Society of Hematology 2023 Annual Meeting of the updated results from the Phase 1 trial (XPORT-MF-034) evaluating selinexor in combination with ruxolitinib in patients with treatment-naïve myelofibrosis (MF) showed encouraging long-term durability. 79% of intent-to-treat (ITT) patients (11 out of 14) treated with 60mg selinexor achieved ≥35% reduction in spleen volume (SVR35) at week 24, and continued to remain in radiographic response as of the August 1, 2023 data cut-off date. In addition, 58% of the ITT patients (7 out of 12) who achieved symptom improvement of ≥ 50% (TSS50) at week 24 also remained in response as of the data cut-off. In general, early cytokine reduction at week 4 was associated with spleen volume reduction at week 24, was sustained until the end of treatment, and is a potential sign of disease modification. Clinical trial collaboration agreement executed with Bristol Myers Squibb (BMS) to evaluate selinexor in combination with BMS' proprietary investigational cereblon E3 ligase modulator (CELMoD™) agent mezigdomide in patients with relapsed/refractory multiple myeloma (MM) progressing after T-cell immunotherapies, potentially adding to the growing body of evidence that selinexor has the potential to show meaningful benefit in combination with MM therapies with differing mechanisms of action; the study of selinexor/mezigdomide enables further evaluation of selinexor's role in maintaining an optimal T-cell environment. XPOVIO Commercial Performance Achieved U.S. net product revenue for the year ended December 31, 2023 of $112 million, compared to $120 million for the year ended December 31, 2022. U.S. net product revenue for the fourth quarter of 2023 was $25 million, compared to $31 million for the fourth quarter of 2022. Although demand for XPOVIO continued its growth in the community setting in 2023, it was adversely impacted in the academic setting due to increased competition in the later-lines. Continued progress in shifting selinexor use into earlier lines of therapy, with patient mix approaching 70% in the second to fourth lines in 2023 versus 55% in 20221. XPOVIO net product revenue was adversely impacted year-over-year by increased utilization of the KaryForward Patient Assistance Program (PAP), due to MM foundation closures2, contributing to ~10% of total demand in 2023 as compared to ~5% in 2022, leading to an estimated impact of ~$6 million. Additionally, increased competition and higher gross-to-net, driven by increased 340B discounts and Medicaid rebates during the year, adversely impacted XPOVIO net product revenue in 2023. Intellectual Property The U.S. Patent and Trademark Office issued patents directed toward the polymorphic form of selinexor present in XPOVIO, pharmaceutical compositions comprising the polymorphic form and methods of treatment using the polymorphic form and the pharmaceutical compositions. The newly issued patents will expire in August 2035. Anticipated Catalysts and Operational Objectives in 2024 and 2025 Present updated exploratory subgroup analysis results in patients with TP53 wild-type EC from the Phase 3 SIENDO trial in 2024. Complete enrollment in pivotal XPORT-EC-042 Phase 3 trial in TP53 wild-type EC in 2H 2024 and report top-line results in 1H 2025. Report updated results from the Phase 1 trial of selinexor in combination with ruxolitinib in patients with treatment-naïve MF in 2024. Report preliminary results from the Phase 2 trial evaluating the efficacy and safety of selinexor monotherapy in subjects with JAK inhibitor-naïve MF and moderate thrombocytopenia in 2H 2024. Report top-line results from pivotal Phase 3 trial of selinexor in combination with ruxolitinib in treatment-naïve MF in 2H 2025. Publish and present efficacy and safety data on selinexor 40mg in combination with pomalidomide and dexamethasone from ongoing STOMP/028 Phase 2 trials in patients with MM in 2024. Report additional data on selinexor's impact on T-cell fitness and potential combinability with multiple agents pre- or post-T-cell therapy in patients with MM in 2024. Complete enrollment in pivotal Phase 3 trial evaluating an oral combination of 40mg selinexor, pomalidomide and dexamethasone in patients with previously treated MM in 2H 2024 and report top-line results in 1H 2025. Maintain the Company's commercial foundation in the competitive MM marketplace, driving increased XPOVIO revenues. Continue global launches and reimbursement approvals for selinexor by partners in ex-U.S. territories. 2024 Financial Outlook Based on its current operating plans, Karyopharm expects the following for full year 2024: Total revenue to be in the range of $140 million to $160 million. Total revenue consists of U.S. XPOVIO net product revenue and license, royalty and milestone revenue earned from partners. U.S. XPOVIO net product revenue to be in the range of $100 million to $120 million. R&D and SG&A expenses to be in the range of $260 million to $280 million, which includes approximately $20 million to $25 million of estimated non-cash stock-based compensation expense. The Company expects that its existing cash, cash equivalents and investments, and the revenue it expects to generate from XPOVIO net product sales, as well as revenue generated from its license agreements, will be sufficient to fund its planned operations into late 2025. Full Year and Fourth Quarter 2023 Financial Results Total revenue: Total revenue for the fourth quarter of 2023 was $33.7 million, compared to $33.6 million for the fourth quarter of 2022.

Cost of sales: Cost of sales for the fourth quarter of 2023 was $1.5 million, compared to $1.9 million for the fourth quarter of 2022. Cost of sales for the year ended December 31, 2023 was $4.9 million, compared to $5.2 million for the year ended December 31, 2022.

R&D expenses for the year ended December 31, 2023 were $138.8 million, compared to $148.7 million for the year ended December 31, 2022. The decrease in R&D expenses in 2023 compared to 2022 was primarily due to a decrease in personnel costs and stock-based compensation attributable to a reduction in headcount and contractors, including severance-related expenses incurred in 2022. These decreases were partially offset by an increase in clinical trial and related costs primarily due to the advancement of the Company's three pivotal Phase 3 trials and the timing of purchases of comparator drug used in the Company's clinical trials.

The decrease in SG&A expenses in 2023 compared to 2022 was primarily due to a decrease in stock-based compensation because of severance-related expenses incurred in 2022. Interest expense: Interest expense for the fourth quarter of 2023 was $6.2 million, compared to $5.9 million for the fourth quarter of 2022. Interest expense for the year ended December 31, 2023 was $23.8 million, compared to $25.0 million for the year ended December 31, 2022.
