Interventions

  • Givinostat — DRUG
    In Part A patients will treated in dose levels at the following daily doses of Givinostat: * 50 mg b.i.d., * 100 mg b.i.d.; * 150 mg b.i.d., * 200 mg b.i.d.; * 150 mg t.i.d.; * 200 mg t.i.d.. Intermediate dose levels and, consequently, additionally dose levels may be used to establish the Maximum Tolerated Dose. In Part B patients will be treated at the Maximum Tolerated Dose established in Part A. The product will be supplied as hard gelatine capsules for oral administration at the strength of 50 mg, 75 mg and/or 100 mg each.

Study Details

This is a two-part, multicenter, open label, non-randomized, phase Ib/II study to assess the safety and tolerability, Maximum Tolerated Dose and preliminary efficacy of Givinostat in patients with JAK2V617F positive Polycythemia Vera. Part A is the dose finding part while Part B is assessing the preliminary efficacy. Patients will be enrolled either in Part A or Part B and transition from one part to the other is not allowed. Eligible patients for this study will have a confirmed diagnosis of Polycythemia Vera according to the revised World Health Organization criteria. Only if the enrolment in Part A is slow (i.e. \< 5 patients enrolled in 3 months), eligibility for this part of the study may be expanded to all patients with chronic myeloproliferative neoplasms. Study therapy will be administered in 28 day cycles (4 weeks of treatment). Disease response will be evaluated according to the European LeukemiaNet criteria after 3 and 6 cycles (i.e. at weeks 12 and 24, respectively) of treatment with Givinostat for both parts of the study. All phlebotomies performed in the first 3 weeks of treatment will not be counted to assess the clinico-haematological response. The study will last up to a maximum of 24 weeks of treatment. However, after completion of the trial, all patients achieving clinical benefit will be allowed to continue treatment with Givinostat (at the same dose and schedule) in a long-term study. Safety will be monitored at each visit throughout the entire duration of the study. Treatment will be administered on an outpatient basis and patients will be followed regularly with physical and laboratory tests, as specified in the protocol; in case of hospitalization, the treatment will be continued or interrupted according to the Investigators' decision.

Arms

  • Experimental: Givinostat
    In Part A patients will treated in dose levels at the following daily doses of Givinostat: * 50 mg b.i.d., * 100 mg b.i.d.; * 150 mg b.i.d., * 200 mg b.i.d.; * 150 mg t.i.d.; * 200 mg t.i.d.. Intermediate dose levels and, consequently, additionally dose levels may be used to establish the Maximum Tolerated Dose. In Part B patients will be treated at the Maximum Tolerated Dose established in Part A. The product will be supplied as hard gelatine capsules for oral administration at the strength of 50 mg, 75 mg and/or 100 mg each.
