NEWTON, Mass. – Karyopharm Therapeutics Inc. (Nasdaq: KPTI) announced today that its Phase 3 SENTRY trial results have been selected for a late-breaking oral presentation at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting, scheduled for May 29 to June 2 in Chicago.

Significance of Late-Breaking Selection

The selection for a late-breaking presentation represents a significant achievement, as ASCO reserves these slots for studies with practice-changing potential or unexpected breakthrough results. This designation suggests the SENTRY trial may have met its primary endpoints or demonstrated clinically meaningful outcomes for myelofibrosis patients.

About the SENTRY Trial

The Phase 3 SENTRY trial is a randomized, double-blind, placebo-controlled study evaluating Karyopharm’s investigational therapy in myelofibrosis patients. Myelofibrosis is a rare bone marrow cancer that disrupts normal blood cell production, affecting approximately 1 in 500,000 people annually.

Market Impact and Implications

Karyopharm, a commercial-stage pharmaceutical company specializing in novel cancer therapies, has been developing treatments that target nuclear export mechanisms. The company’s lead compound, selinexor, is already approved for multiple myeloma and diffuse large B-cell lymphoma.

The myelofibrosis treatment landscape remains challenging, with current therapies primarily focused on symptom management rather than disease modification. A successful SENTRY trial could represent a significant advancement for patients facing this difficult-to-treat malignancy.

What’s Next

The presentation at ASCO 2026 will provide the first public disclosure of detailed trial results. Healthcare professionals, investors, and patient advocacy groups will closely monitor the data for potential regulatory filing implications and treatment paradigm shifts in myelofibrosis care.
