简要总结
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.
详细描述
This is a multicenter, open label, long-term study testing the long-term safety, tolerability and efficacy of givinostat in patients with PV, ET, primary MF, Post-PV MF, Post-ET MF following core protocols in cMPN (i.e. Study DSC/07/2357/28, Study DSC/08/2357/38, Study DSC/12/2357/45 and/or all further core protocols in cMPN), 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).
Eligible patients will have tolerated previous givinostat treatment and achieved a clinical benefit at the end of the core protocols; alternatively, eligible patients are participating in 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). In addition, patients must have tolerated previous givinostat treatment and achieved a clinical benefit at the end of core protocols or compassionate use program with givinostat, assessed by the Investigator according to the revised clinico-haematological ELN response criteria (for PV and ET) and EUMNET response criteria (for MF).
After providing informed written consent before undertaking any protocol-related procedure, an unique patient identification code (patient ID) will be assigned to each patient, will identify the patient throughout his/her participation in the study and can never be reused in case of premature drop-out.
Patients will continue at their last tolerable dose and treatment schedule of givinostat monotherapy. If patients previously received givinostat in combination with other drugs (e.g. hydroxyurea) during a core protocol or a compassionate use program , they will be treated at the last tolerable dose of the combination. In general, the dose of study drug may not be increased during this study. However, since the Maximum Tolerated Dose (MTD) of givinostat as chronic treatment has been recently identified and proven tolerable in Polycythenia Vera patients (i.e. 100 mg b.i.d.), selected patients may be eligible for escalation of their givinostat dose up to this level upon consultation with and written permission by Italfarmaco S.p.A. or its designee.
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 clinico-haematological ELN response criteria (for PV and ET) and EUMNET response criteria (for MF). Patients will be considered for continued treatment on the basis of their clinical response:

入选标准
- •Patients must have completed givinostat treatment on at least one core study in chronic myeloproliferative neoplasms, or patients must be participating in a compassionate use program with givinostat AND Patients must have tolerated previous givinostat treatment and achieved a clinical benefit at the end of core protocols or compassionate use program with givinostat, assessed by the Investigator according to the revised clinico-haematological ELN response criteria (for PV and ET) and EUMNET response criteria (for MF);
- •Patients must be able to provide informed consent and be willing to sign an informed consent form;
- •Adult patients (age ≥ 18 years) of both genders with established diagnosis of chronic myeloproliferative neoplasms according to the revised WHO criteria;
- •Patients must have an Eastern Cooperative Oncology Group performance status < 3 at baseline;

研究组 & 干预措施
givinostat
Patients will continue at their last tolerable dose and treatment schedule of givinostat monotherapy. Givinostat is a histone-deacetylases inhibitor. 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.
If patients previously received givinostat in combination with other drugs during a core protocol or a compassionate use program, they will be treated at their last tolerable dose of this combination.

结局指标
主要结局
Long-term safety and efficacy
时间窗: 3 months
To obtain information on the long-term safety and tolerability of givinostat in patients with chronic myeloproliferative neoplasms following core protocols or compassionate use program: * Number of patients experiencing adverse events; * Type, incidence, and severity of treatment-related adverse events. To determine the long term efficacy of givinostat in patients with chronic myeloproliferative neoplasms following core protocols or compassionate use program: * For Polycythemia Vera and Essential Thrombocythemia, Complete response and partial response rate according to the revised clinico-haematological European LeukemiaNet response criteria; * For Myelofibrosis, complete response, major response, moderate response and minor response rate according to European Myelofibrosis Network response criteria. Note that these assessment will be repeated periodically (each 3 months) during the study. In fact, the treatment will continue up to Marketing Authorisation of givinostat.
