Long-term Study Evaluating the Effect of Givinostat in Patients With Chronic Myeloproliferative Neoplasms

This is a multicenter, open label, long-term study testing the long-term safety, tolerability and efficacy of givinostat in patients with Polycythemia Vera, Essential Thrombocythemia, primary Myelofibrosis, Post-Polycythemia Vera Myelofibrosis, Post-Essential Thrombocythemia Myelofibrosis following core protocols in chronic myeloproliferative neoplasms and/or patient-named compassionate use program (if regulated/allowed by the local regulations, e.g. for Italy D.M. 8/5/2003 "Uso terapeutico di medicinale sottoposto a sperimentazione clinica" published on G.U. n. 173 of 28 July 2003, and the following amendments). Patients will continue at their last tolerable dose and treatment schedule of givinostat monotherapy. If patients previously received givinostat in combination with other drugs during a core protocol or a compassionate use program (if regulated/allowed by the local regulations, e.g. for Italy D.M. 8/5/2003 "Uso terapeutico di medicinale sottoposto a sperimentazione clinica" published on G.U. n. 173 of 28 July 2003, and the following amendments), they will be treated at the last tolerable dose of the combination. Assessment of safety and efficacy will be performed at each quarterly visit and each visit will also include laboratory tests and ECG examination. During the visits the clinical benefit will be assessed by Investigator according to the revised European LeukemiaNet response criteria (for PV and ET) and EUMNET response criteria (for MF). The dose of Givinostat will be modified for protocol specified toxicities. The treatment may continue up to Marketing Authorization of givinostat, currently planned in the next 5 years (note: only for Germany, this long-term study is initially limited up to 2 years of treatment). Patients may discontinue study treatment at any time and remain on study therapy as long as they derive clinical benefit. Safety will be monitored at each visit throughout the entire duration of the study. In case the approved label will not cover the whole study population, givinostat will be provided by the Sponsor to those patients not fulfilling the criteria for the approved label of the drug that are still deriving benefit from givinostat at the time of its commercial availability.
