Exclusion: Prior treatment of PV with Transmembrane serine protease 6 (TMPRSS6) inhibitors, including sapablursen, or hepcidin mimetics; Clinically significant thrombosis (eg, myocardial infarction, stroke, deep vein thrombosis or splenic vein thrombosis) within 1 month prior to randomization; Any serious or unstable medical condition or uncontrolled psychiatric condition that would interfere with their ability to comply with study requirements; Participants who require phlebotomy at Hct levels <45%; Meet the criteria for post-PV myelofibrosis as defined by the International Working Group-Myeloproliferative Neoplasms Research and Treatment.
