Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a Phase 2b open label study of an orally administered LSD1 inhibitor, Bomedemstat (MK-3543, formerly called IMG-7289), in patients with essential thrombocythemia.

This study investigates the following:

* The safety and tolerability of Bomedemstat
* The pharmacodynamic effect of Bomedemstat

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase 2 multi-center, open-label study evaluating the safety, efficacy and pharmacodynamics of Bomedemstat administered orally once daily in patients with essential thrombocythemia (ET). Patients will be dosed with Bomedemstat for 169 consecutive days in the Initial Treatment Period (ITP). Qualifying patients may continue to receive Bomedemstat in the Additional Treatment Period (ATP).

Safety will be evaluated by clinical assessments of safety parameters i.e., safety laboratory testing, adverse event reporting, physical examination and vital sign assessments. Pharmacodynamics will be evaluated by hematology assessment, patient reported symptom burden, change in spleen size by palpation and other measures.

To ensure safety, a Safety Advisory Board will perform periodic reviews of safety parameters and pharmacodynamic markers.
