Phase 2/3
A Clinical Trial of Bomedemstat in Participants With Polycythemia Vera (MK-3543-025).
NCT07722611 · tracked via the Priya Life Science USA tracker
Condition(s) studied
Polycythemia Vera
Investigational drug(s) / intervention(s)
Bomedemstat: Oral Capsule
Ruxolitinib: Oral Tablet
Ropeginterferon alfa-2b: Subcutaneous Solution
Study summary
Researchers are looking for new ways to treat polycythemia vera (PV). People with PV may receive treatment to lower the number of red blood cells in the blood, but the usual treatments may not work for everyone. Researchers want to learn if a trial medicine called bomedemstat, also called MK-3543, can treat PV. In this study, researchers will compare bomedemstat to 2 usual treatments for PV.
The goal of this study is to learn if more participants who take bomedemstat reach healthy blood cell counts and avoid major health problems from PV, compared to those who receive a usual treatment.

Primary outcome measure(s)
- Clinicohematologic Response (CHR) Rate — Up to approximately Week 52
CHR Rate is defined as all of the following: (i) a confirmed hematologic remission sustained for at least 12 consecutive weeks by Week 40 through Week 52, (ii) and absence of any of the following as assessed by the adjudication committee Week 52: thrombotic event; major hemorrhagic events; disease progression to myelofibrosis (MF) or myelodysplastic syndrome (MDS)/acute myeloid leukemia (AML). CHR will begin on the date of the first confirmed assessment achieving CHR criteria and will end on the earliest date of the following: 1) day of the first confirmed assessment not achieving CHR criteria, 2) date of first major hemorrhagic event or thrombotic event as assessed by the adjudication committee, or 3) disease progression as assessed by the adjudication committee. The CHR rate will be presented.
