Merck initiates Phase 3 trial, Shorespan-007, evaluating bomedemstat, an LSD1 inhibitor, for treating essential thrombocythemia (ET) patients not previously treated with cytoreductive therapy. The trial aims to compare bomedemstat with standard care chemotherapy, hydroxyurea, with a focus on durable clinicohematologic response rate and patient-reported outcomes. Bomedemstat holds FDA Orphan Drug and Fast Track Designations for ET and myelofibrosis.
