- Age ≥ 60 years, and/or
- Prior thrombosis.
- Patients must be in need of treatment at screening, defined by the presence of at least one of the following:
- HCT ≥ 45% or HCT < 45% with at least 1 phlebotomy performed in the 3 months before screening, or
- WBC count > 10 × 109/L, or
- PLT count > 400 × 109/L.
- Patients must have normalized HCT (i.e., HCT < 45%) at randomization Extended Treatment
- Inclusion Criteria
- Patients must have completed the Week 48 visit of the DSC/08/2357/32 core treatment phase and:
1. if the patient received givinostat, a complete hematological response (CHR) at Week 48 shall be achieved

- Exclusion Criteria
- Patients pre-treated with HU with a documented history of resistance or intolerance to HU defined by the original ELN criteria
- Patients with a QTcF value of > 450 msec for males and > 460 msec for females at the Screening visit (as the mean of 3 consecutive readings 5 minutes apart in the event a first ECG demonstrates a prolonged QTcF interval); congenital or acquired history of QTc prolongation or ventricular arrhythmias, at the Screening visit
- Splanchnic thrombosis and/or thrombosis of the cerebral venous sinuses and/or splenectomy in the medical history
- Patients with clinically significant cardiovascular disease
- Patients with myocardial infarction, stroke or unstable angina within the 6 months prior to screening.
- Patients with inadequate liver or renal function at screening
- Uncontrolled hypertriglyceridemia at screening, i.e., triglycerides ˃ 1.5 × ULN
- Previous treatment with a JAK2 or HDAC inhibitor or 32-phosphorus (radioactive isotope) therapy.
- Patients being treated concurrently with any investigational agent or prior participation in an interventional clinical study within the 30 days prior to screening or within 5 half-lives of the investigational product, whichever is longer.
- Pregnant or nursing women Extended treatment phase
- Exclusion criteria
- For patients randomized to givinostat in the core treatment phase
