Karyopharm Therapeutics (Nasdaq: KPTI) reported Q2 2025 financial results with total revenue of $37.9 million, including U.S. XPOVIO net product revenue of $29.7 million, up 6% year-over-year. The company reaffirmed its full-year 2025 total revenue guidance of $140-155 million while updating U.S. XPOVIO revenue guidance to $110-120 million.

Key developments include the imminent completion of patient screening for the Phase 3 SENTRY trial in myelofibrosis, with top-line results expected in March 2026. However, the company faces financial challenges with $52.0 million in cash as of June 30, 2025, down from $109.1 million at year-end 2024. Karyopharm is actively exploring financing transactions and strategic alternatives to extend its cash runway beyond the October 2025 maturity of its convertible notes.

Karyopharm Therapeutics (Nasdaq: KPTI) ha comunicato i risultati finanziari del secondo trimestre 2025 con ricavi totali di 37,9 milioni di dollari, di cui 29,7 milioni di dollari di ricavi netti negli Stati Uniti da XPOVIO, in aumento del 6% su base annua. L'azienda ha confermato la guidance sui ricavi totali per l'intero 2025 di 140-155 milioni di dollari aggiornando contestualmente la guidance per i ricavi statunitensi di XPOVIO a 110-120 milioni di dollari.

Tra gli sviluppi principali figura il prossimo completamento dello screening dei pazienti per lo studio di fase 3 SENTRY nella mielofibrosi, con risultati principali attesi per marzo 2026. Tuttavia, la società affronta difficoltà finanziarie con 52,0 milioni di dollari in cassa al 30 giugno 2025, in calo rispetto ai 109,1 milioni di fine 2024. Karyopharm sta attivamente valutando operazioni di finanziamento e alternative strategiche per estendere la propria liquidità oltre la scadenza di ottobre 2025 delle obbligazioni convertibili.

Insights

Karyopharm faces cash runway concerns despite modest XPOVIO growth; approaching critical clinical milestones amid urgent financing needs.

Karyopharm's Q2 results reveal a concerning financial position despite modest commercial progress. While U.S. XPOVIO revenue increased 6% year-over-year to $29.7 million, the company's cash position has deteriorated significantly to just $52 million as of June 30, down from $109.1 million at year-end 2024.

The liquidity crisis is evident in management's explicit statement that current funds will only support operations until the $24.5 million convertible notes mature in October 2025. This tight timeline explains why they're actively pursuing financing transactions and strategic alternatives with the help of Centerview Partners.

On the clinical front, the nearing completion of enrollment in the Phase 3 SENTRY myelofibrosis trial represents a critical milestone, with topline results expected in March 2026. However, this timeline creates a problematic gap between the October 2025 debt maturity and potential clinical catalysts that could drive value.

The updated revenue guidance shows reduced confidence in XPOVIO's commercial performance, with U.S. product revenue guidance lowered to $110-120 million while maintaining overall revenue guidance of $140-155 million, suggesting increased reliance on partner revenue.

The company's negative cash flow remains substantial, with quarterly net loss of $37.3 million despite cost-cutting initiatives that reduced R&D expenses by $5.6 million and SG&A by $2.6 million year-over-year. Interest expenses have increased 26% to $11.2 million, further straining finances.

While the myelofibrosis program shows promise, particularly in addressing patients with thrombocytopenia, investors should recognize that Karyopharm faces an existential financing challenge that will likely result in significant dilution or strategic transactions before clinical readouts can potentially drive value.

NEWTON, Mass., Aug. 11, 2025 /PRNewswire/ -- Karyopharm Therapeutics Inc. (Nasdaq: KPTI), a commercial-stage pharmaceutical company pioneering novel cancer therapies, today reported financial results for the second quarter ended June 30, 2025 and highlighted progress on key clinical development programs.

"As we continue to seek potential financing and strategic alternatives to extend our cash runway and enhance liquidity, I am excited to announce that we are in our final weeks of enrolling our Phase 3 SENTRY trial and are on track to report top-line data from this pivotal trial in March 2026," said Richard Paulson, President and Chief Executive Officer of Karyopharm. "Over the past seven years, we have led the development of a growing body of evidence supporting the role of XPO1 inhibition in myelofibrosis and are optimistic about selinexor's potential in this disease. Completing enrollment is a very important step in our journey to potentially redefine the standard-of-care in myelofibrosis and provide a transformational opportunity for patients and our organization, pending positive data."

Second Quarter 2025 Highlights

XPOVIO Commercial Performance

  • U.S. net product revenue was $29.7 million in the second quarter of 2025 compared to $28.0 million in the second quarter of 2024.
  • Demand for XPOVIO was consistent in the second quarter of 2025 compared to the second quarter of 2024, with the community setting continuing to drive approximately 60% of overall net product revenue.
  • Expanded global patient access for selinexor is translating into growth in royalty revenue from Menarini, Antengene and other international partners. Royalty revenue increased 28% to $1.6 million in the second quarter of 2025 compared to the second quarter of 2024.

Research and Development (R&D) Highlights

Myelofibrosis

  • The Phase 3 SENTRY trial (XPORT-MF-034; NCT04562389) is nearing full enrollment and the Company expects new patient screening will be closed this week. SENTRY is targeting 350 patients for enrollment and is evaluating 60 mg once-weekly selinexor in combination with ruxolitinib compared to ruxolitinib plus placebo. The preliminary baseline characteristics for patients enrolled in SENTRY are representative of the intended patient population. In addition, preliminary blinded aggregate safety data from the first 61 patients with a median follow-up of greater than 12 months may suggest improvements in both hematologic and non-hematologic treatment emergent adverse events as compared to the Phase 1 data evaluating selinexor 60 mg weekly in combination with standard of care ruxolitinib in JAKi-naïve myelofibrosis patients, as well as historical ruxolitinib monotherapy data. The Company cautions that the preliminary baseline characteristics and preliminary blinded aggregate safety data may not be reflective of the actual top-line data.
  • Presented data from the XPORT-MF-035 (NCT04562870) Phase 2, randomized, open-label trial of selinexor versus physician's-choice in hard-to-treat patients with heavily pretreated myelofibrosis (N=24) at the European Hematology Association (EHA) 2025 Congress. The data suggest the potential for single-agent clinical activity with selinexor, including spleen volume reduction, symptom improvement, hemoglobin stabilization, and evidence of disease modification. A copy of the poster that was presented at EHA, titled "A Study to Evaluate Single-Agent Selinexor Versus Physician's Choice in Participants With Previously Treated Myelofibrosis" is available under "Publications and Presentations" in the Investor section of the Company's website.
  • The Company continues to enroll JAKi-naïve myelofibrosis patients with moderate thrombocytopenia (defined as having platelet counts between 50,000 and 100,000) in the selinexor 60 mg cohort of the Phase 2 SENTRY-2 trial (XPORT-MF-044; NCT05980806). The Company plans to amend the protocol for SENTRY-2 to also include patients with platelet counts above 100,000, which will expand the number of patients that are eligible to participate in the trial. Approximately 10% to 15% of patients with myelofibrosis have platelet counts between 50,000 and 100,0001. The Company expects to report top-line data from all patients in the 60 mg cohort with at least 24 weeks of follow-up in 2026.

Endometrial Cancer

  • Enrollment continues in the Phase 3 XPORT-EC-042 (NCT05611931) trial evaluating selinexor as a maintenance-only therapy following systemic therapy versus placebo in patients with TP53 wild-type advanced or recurrent endometrial cancer.

Multiple Myeloma

  • Enrollment of approximately 120 patients in the Phase 3 XPORT-MM-031 trial (EMN29; NCT05028348) was completed in the fourth quarter of 2024. The trial is being conducted in collaboration with the European Myeloma Network and is evaluating the all-oral combination of selinexor 40 mg, pomalidomide and dexamethasone (SPd40) in patients with previously treated multiple myeloma who received an anti-CD38 in their immediate prior line of therapy.

Anticipated Catalysts and Operational Objectives

Myelofibrosis

  • The Company expects new patient screening will be closed for the Phase 3 SENTRY trial this week with top-line data expected in March 2026.

Multiple Myeloma

  • Maintain the Company's commercial foundation in the increasingly competitive multiple myeloma marketplace and drive increased XPOVIO revenues.
  • Continue to support global launches by our partners following regulatory and reimbursement approvals for selinexor in ex-U.S. territories.
  • Continue to follow patients that are enrolled in the Phase 3 XPORT-MM-031 (EMN29) trial. The Company expects to report top-line data from this event-driven trial in the first half of 2026.

Endometrial Cancer

  • Continue to enroll patients into the Phase 3 XPORT-EC-042 trial of selinexor as a maintenance monotherapy for patients with TP53 wild-type advanced or recurrent endometrial cancer. The Company expects to report top-line data from this event-driven trial in mid-2026.

2025 Financial Outlook

Based on its current operating plans, Karyopharm expects the following for full year 2025:

  • Total revenue to be in the range of $140 million to $155 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 $110 million to $120 million.
  • R&D and selling, general and administrative (SG&A) expenses to be in the range of $240 million to $250 million.
  • The Company expects its existing liquidity, including the revenue it expects to generate from XPOVIO net product sales and its license agreements, will be sufficient to fund its planned operations to the maturity of its senior convertible notes due October 2025 (Remaining 2025 Notes). Excluding the $24.5 million Remaining 2025 Notes maturity and its $25.0 million minimum liquidity covenant, the Company expects it would have sufficient liquidity to fund planned operations into January 2026. The Company, with the assistance of its advisors, including its financial advisor Centerview Partners, is exploring potential financing and strategic alternatives to enhance liquidity and maximize value.

Second Quarter 2025 Financial Results

Total revenue: Total revenue for the second quarter of 2025 was $37.9 million, compared to $42.8 million for the second quarter of 2024. 

Net product revenue: Net product revenue for the second quarter of 2025 was $29.7 million, compared to $28.0 million for the second quarter of 2024.

License and other revenue: License and other revenue for the second quarter of 2025 was $8.2 million, compared to $14.8 million for the second quarter of 2024. The decrease was primarily attributable to $6.0 million of non-recurring license-related revenue recognized during the second quarter of 2024.

Cost of sales: Cost of sales for the second quarter of 2025 was $1.1 million, compared to $1.5 million for the second quarter of 2024. Cost of sales reflects the costs of XPOVIO units sold and the costs of products sold to our partners.

R&D expenses: R&D expenses for the second quarter of 2025 were $32.8 million, compared to $38.4 million for the second quarter of 2024. The decrease was due to a reduction in personnel costs and stock-based compensation costs primarily due to a reduction in headcount and contractors, coupled with lower clinical trial and related costs due to the reduced scope of our Phase 3 multiple myeloma trial.

SG&A expenses: SG&A expenses for the second quarter of 2025 were $28.5 million, compared to $31.1 million for the second quarter of 2024. The decrease was primarily due to the realization of previously implemented cost reduction initiatives.

Interest income: Interest income for the second quarter of 2025 was $0.6 million, compared to $1.9 million for the second quarter of 2024. The decrease was due to a lower cash and investments balance quarter-over-quarter.

Interest expense: Interest expense for the second quarter of 2025 was $11.2 million, compared to $8.9 million for the second quarter of 2024. The increase was related to a full quarter of interest on the term loan and convertible debt that were issued in the second quarter of 2024.

Gain on Extinguishment of Debt and Other (expense) income: Other expense for the second quarter of 2025 was $2.2 million compared to $14.3 million of other income for the second quarter of 2024. The change is attributable to recurring non-cash fair value remeasurements related to the refinancing transactions that were completed in the second quarter of 2024. The refinancing transactions also resulted in a $44.7 million gain on extinguishment of debt during the second quarter of 2024.

Net (loss) income: Karyopharm reported a net loss of $37.3 million, or $4.32 net loss per basic and diluted share, for the second quarter of 2025, compared to net income of $23.8 million, or $2.26 net income per basic share and $2.97 net loss per diluted share, for the second quarter of 2024. Net (loss) income included non-cash stock-based compensation expense of $3.8 million and $5.4 million for the second quarters of 2025 and 2024, respectively.

Cash position: Cash, cash equivalents, restricted cash and investments as of June 30, 2025 totaled $52.0 million, compared to $109.1 million as of December 31, 2024.
