Summary: The goal of this clinical trial is to compare the efficacy and safety of givinostat to hydroxyurea in Jak2V617F-positive high risk polycythemia vera patients.
Eligibility:

Inclusion Criteria:

- Patients must have been diagnosed with PV according to the 2016 WHO criteria within 3 years before randomization

- Patients must have JAK2V617F-positive disease

- Patients with PV must meet the definition of HR for thrombosis (i.e., HR) at screening as follows:

- 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

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
