Phase IIA Study of the HDAC Inhibitor ITF2357 in Patients With JAK-2 V617F Positive Chronic Myeloproliferative Diseases

2 dicembre 2019 aggiornato da: Italfarmaco

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).

Descrizione dettagliata

This is a non-randomized, open-label, Phase IIA pilot study testing efficacy and safety of ITF2357 in a population of patients with JAK2V617F positive myeloproliferative diseases. All recruited patients received an initial dose of 50 mg b.i.d. of ITF2357 that was subsequently escalated to 50 mg t.i.d. in case of lack of significant toxicity. Treatment lasted up to a maximum of 24 cumulative weeks of drug administration. The study was carried out in Italy. Enrolled patients were subjects of both genders, with an established diagnosis of polycythemia vera (PV), essential thrombocythemia (ET) and myelofibrosis (MF) according to the revised WHO criteria.

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Number of Patients With Objective Responses (Complete, Major, Moderate or Minor Responses), in Terms of Best Overall Response
Lasso di tempo: 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

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Change in JAK2 Mutated Allele Burden
Lasso di tempo: 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
Lasso di tempo: 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
