Summary
Primary Objective:
To evaluate efficacy and safety of ITF2357 in the treatment of patients with JAK2V617F positive myeloproliferative diseases [Polycythemia Vera (PV), Essential Thrombocytosis (ET), Myelofibrosis (MF)]. Efficacy was evaluated by ad hoc haematological and clinical criteria for PV and ET, and by internationally established response criteria (EUMNET criteria) for MF. Safety was evaluated by number of subjects experiencing an Adverse Event (AE), type, frequency, severity, timing and relatedness of AEs, including changes in vital signs and clinical laboratory results.
Secondary Objective:
To evaluate the JAK2 mutated allele burden by quantitative Real-Time Polymerase Chain Reaction (qRTPCR).
Eligibility Criteria
Inclusion Criteria
- Signed Informed Consent Form
- Male or female, age ≥ 18 years
- Confirmed diagnosis of PV/ET/MF according to the revised World Health Organisation criteria
- JAK-2 V617F positivity
- In need of cytoreductive therapy when hydroxyurea is not indicated (e.g. young patients) or when refractoriness to the drug is documented
Exclusion Criteria
- Active bacterial or fungal infection requiring antimicrobial treatment on Day 1
- Patients of childbearing potential without a negative pregnancy test prior to initiation of the study drug
- Pregnancy or lactation
- A marked baseline prolongation of QT/QTc interval (e.g. repeated demonstration of a QTc interval > 450 ms, according to Bazett's correction formula - see appendix G for the formula)
- The use of concomitant medications that prolong the QT/QTc interval (see appendix F for full list)
- Concomitant acute coronary syndromes; uncontrolled hypertension
- New York Heart Association (NYHA) Grade II or greater congestive heart failure
- History of any cardiac arrhythmia requiring medication (irrespective of its severity)
- A history of additional risk factors for Torsade de Pointes (e.g., heart failure, hypokalemia, family history of Long QT Syndrome)
- Active Epstein Barr Virus (EBV) infection (i.e. positive serology IgM)
- Known HIV infection
- Active hepatitis B and/or C infection
- History of other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates use of an investigational drug or that might affect interpretation of the results of the study or render the subject at high risk from treatment complications
