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


About the study

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.

Who can take part

You may be eligible to participate in the study if you meet the following criteria:


  1. 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);
  2. Patients must be able to provide informed consent and be willing to sign an informed consent form;
  3. Adult patients (age ≥ 18 years) of both genders with established diagnosis of chronic myeloproliferative neoplasms according to the revised WHO criteria;
  4. Patients must have an Eastern Cooperative Oncology Group performance status < 3 at baseline;
  5. Acceptable organ function within 7 days of initiating study drug;
  6. Use of an effective means of contraception for women of childbearing potential and men with partners of childbearing potential;
  7. Willingness and capability to comply with the requirements of the study.


  1. Pregnancy or nursing (lactating) women, where pregnancy is defined as the state of a female after conception, confirmed by a positive human Chorionic Gonadotropin (hCG) laboratory test (i.e. > 5 mIU/mL) and until the termination of gestation;
  2. A clinically significant corrected QT interval prolongation at baseline;
  3. Use of concomitant medications known to prolong the corrected QT interval;
  4. Clinically significant cardiovascular disease including:
  5. Uncontrolled hypertension, myocardial infarction, unstable angina at screening;
  6. New York Heart Association Grade II or greater congestive heart failure;
  7. History of any cardiac arrhythmia requiring medication (irrespective of its severity);
  8. A history of additional risk factors for Torsade de Point;
  9. Active virus infection including human HIV, HBV and HCV;
  10. Platelets count < 100 x109/L within 14 days before enrolment (i.e. the receipt of the Patient ID);
  11. Absolute neutrophil count < 1.2 x109/L within 14 days before enrolment (i.e. the receipt of the Patient ID);
  12. Total serum bilirubin > 1.5 1.5 x ULN except in case of Gilbert's disease or pattern consistent with Gilbert's disease;
  13. Serum Aspartate aminotransferase/Alanine aminotransferase (AST/ALT) > 3 times the upper normal limit;
  14. Serum Cystatin C > 2 x ULN for two subsequent evaluations (i.e. if the value of serum Cystatin C is >2 x ULN, the test will be repeated once, and if the value is again > 2 x ULN, this becomes an exclusioncriterion);
  15. Uncontrolled hypertriglyceridemia at baseline, i.e. triglycerides ˃ 1.5 x ULN in fasting state.
  16. History and/or presence of other diseases, metabolic dysfunctions, physical examination findings, or clinical laboratory findings 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 patient at high risk from treatment complications or significantly alter the absorption of the study drug;
  17. Any investigational drug other than givinostat within 28 days before enrolment. Notably, the use of such medications within 28 days or 6 half-lives
  18. whichever is longer
  19. prior to the first dose of study drugs (i.e. Day 1) and during the study through all the study conduct (including any safety follow-up [FU] visit) is prohibited;
  20. Use of concomitant medications known to inhibit Pgp;
  21. Patients with known hypersensitivity to the components of potential study therapy.
