Phase IIA Study of the HDAC Inhibitor ITF2357 in Patients With JAK-2 V617F Positive Chronic Myeloproliferative Diseases
A Phase IIA Study of the Histone-deacetylase Inhibitor ITF2357 in Patients With JAK-2 V617F Positive Chronic Myeloproliferative Diseases
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).

Number of Patients With Objective Responses (Complete, Major, Moderate or Minor Responses), in Terms of Best Overall Response
Časové okno: Every single week from week 1 to week 24 of treatment
|
Patients with Objective Response were defined as those patients achieving a complete, major, moderate or minor (only for Myelofibrosis patients) response during the experimental treatment course. The "best response" is reported hereunder by intensity of response. |
Every single week from week 1 to week 24 of treatment

Change in JAK2 Mutated Allele Burden
Časové okno: At screening, at week 12, at week 24, at the end of treatment (EOT) visit
|
This outcome was assessed by quantitative real time Polymerase Chain Reaction (RT PCR). At each time point, the number of patients is the following: Screening: N=29 Week 12: N=20 Week 24: N=18 EOT: N=24. End of treatment corresponds to the last visit performed before treatment discontinuation. |
At screening, at week 12, at week 24, at the end of treatment (EOT) visit

Number of Subject Experiencing an Adverse Event
Časové okno: At weekly visits (Days 8, 15, 22, 36, 43, 50, 64, 71, 78, 99, 127, 155); At monthly visits (Days 29, 57, 85 113, 141,169); at end of treatment visit

An adverse event (AE) is any untoward occurrence in a patient or clinical investigation subject administered with a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An AE can therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. The adverse events must to be followed to the end of study (28 days after the last study drug intake). A serious AE (SAE) is defined as an untoward (unfavourable) medical occurrence that at any dose results in death, or is life-threatening or requires inpatient hospitalisation or prolongation of existing hospitalisation, or results in persistent or significant disability/incapacity or is a congenital anomaly/birth defect. |
At weekly visits (Days 8, 15, 22, 36, 43, 50, 64, 71, 78, 99, 127, 155); At monthly visits (Days 29, 57, 85 113, 141,169); at end of treatment visit
