Arms of the Study
Arm 1
Arm Type
Experimental
Arm Label
ITF2357
Arm Description
ITF2357 was supplied as hard gelatine capsules for oral administration at the strength of 100 or 50 mg. Patients had to receive ITF2357 100 mg x 2/die at 12-hour intervals, in fed conditions, for three consecutive months.
Outcomes
Primary Outcome Measures
Rate of complete response (CR) or partial response (PR) to ITF2357 in all patients
ITF2357 was given at 100 mg x 2/die for up to three months. A positive response was defined to be a patient experiencing a complete or partial remission.
Complete remission (CR) Absence of lymphadenopathy, hepatomegaly, splenomegaly or constitutional symptoms.
Normal blood count: neutrophils ≥1.5x109/L, platelets >100x109/L, lymphocytes ≤4.0x109/L, Hb >11.0 g/dL (not supported by transfusion), BM biopsy: normal cellularity, lymphocytosis <30%.
Partial remission (PR)
≥50% reduction in blood lymphocytes and ≥50% reduction in lymphadenophaty and/or 50% reduction in hepatomegaly and/or splenomegaly. Neutrophils ≥1.5x109/L or 50% improvement over baseline, platelets >100x109/L or 50% improvement over baseline, Hb >11.0 g/dL or 50% improvement over baseline (not supported by transfusion) It was considered PR
CR with nodular infiltrates at bone marrow biopsy (RPn)
CR with persistent anemia and thrombocytopenia therapy-related
Secondary Outcome Measures
Total rate of responders (complete+partial responders)
ITF2357 was given at 100 mg x 2/die for up to three months
Six months progression free survival.
ITF2357 was given at 100 mg x 2/die for up to three months
Number of subjects experiencing an adverse vents (AE), type, frequency, severity, timing and relatedness of AE
ITF2357 was given at 100 mg x 2/die for up to three months

5. Study Description
Brief Summary
Primary objective:
- To determine overall response-rate, complete response (CR) or partial response (PR)
Secondary objectives:
To assess the safety and tolerability of ITF2357;
to assess total rate of responders (complete + partial responders);
to determine the 6 months progression free survival;
to determine the effects of the drug on haematological parameters.
Detailed Description
This is an open label, un-controlled, phase II, pilot clinical trial testing ITF2357 in a population of CLL patients relapsed after or refractory to conventional chemotherapy or relapsed after autologous bone marrow transplantation.
Patient received ITF 2357 orally at the dose of 100 mg x 2/die for three months with subsequent dose modifications if requested by the patient's conditions.
The study was prematurely discontinued due to recruitment problems. Since February 2008, date of first patient's first visit, until April 2009, date of early study discontinuation, only 3 patients were enrolled. The Sites involved in the study were 6 but only two actively recruited patients.
CLL is the most frequent type of leukemia in the western world and affects mainly elderly individuals, although about one third of patients are less than 60 years of age at diagnosis.
CLL is a heterogeneous disease characterised by a surprisingly diverse clinical course with patients that may have an overall survival time ranging from months to decades.
CLL accounts for approximately 7000 new cases and 4500 deaths per year in the US.
Chemotherapeutic treatment of CLL is largely ineffective and despite new emerging therapies, CLL still remains an incurable disease.
ITF 2357 is a novel and proprietary molecule synthesized by Italfarmaco S.p.A. Research Laboratories, provided with an established and powerful HDAC-inhibitory activity (see below for further details). It is being developed for a range of possible clinical applications both in oncohaematological conditions and in chronic inflammatory diseases. The former application is consistent with the well known antitumor pharmacological properties of HDAC-inhibitors as a family (i.e. cell-cycle arrest, pro-apoptotic and cell-differentiating effects); the latter application (chronic inflammation) is based of the demonstrated anticytokine effect of ITF 2357.
