Karyopharm Reports Q2 2026 Financial Results and Highlights Progress Toward Myelofibrosis sNDA Submission

13 Aug 2026 · 13 Aug, 5:12 pm

Summary

Karyopharm Therapeutics reported second quarter 2026 total revenue of $33.4 million, down from $37.9 million in the prior year, primarily due to a decrease in license and other revenue. However, U.S. XPOVIO net product revenue saw a slight increase to $30.8 million from $29.7 million year-over-year. The company is on track to submit its sNDA for selinexor in myelofibrosis in August and reaffirmed its full-year 2026 total revenue guidance. Despite a wider net loss of $67.0 million in Q2 2026 compared to $37.3 million in Q2 2025, management highlighted progress in its myelofibrosis program and constructive engagement with the FDA.

Management Comments

Richard Paulson

Our planned submission under the Accelerated Approval pathway represents the beginning of an important new chapter for Karyopharm and an important milestone for the myelofibrosis community. If approved, selinexor plus ruxolitinib would become the first approved combination therapy for patients with myelofibrosis, introducing a novel therapeutic mechanism for the treatment of this disease within the multi-billion-dollar U.S. marketplace. Our planned submission follows productive engagements with the FDA and reflects the speed, focus, urgency and extraordinary commitment of our teams. We look forward to continuing to work closely with the FDA. Together with the continued scientific engagement we are seeing across the myelofibrosis community, we believe the strength and consistency of the SENTRY data reinforce the potential of selinexor to fundamentally change the treatment of patients with myelofibrosis.
