Summary

Objectives: Primary objective: to establish the histological effects of Givinostat versus placebo administered over 12 months. Secondary Objectives: * To establish the macroscopic muscle effects of Givinostat versus placebo administered over 12 months assessed by Magnetic Resonance Imaging (MRI)/Magnetic Resonance Spectroscopy (MRS). * To determine the other histological effects of Givinostat versus placebo administered over 12 months. * To establish the efficacy of Givinostat versus placebo administered chronically over 12 months in slowing disease progression. * To assess the safety and tolerability of Givinostat versus placebo administered chronically. * To evaluate the pharmacokinetic (PK) profile of Givinostat administered chronically in the target population. * To evaluate the impact of Givinostat versus placebo administered chronically on quality of life and activities of daily living.

Detailed description

This was a phase 2, randomised, double-blind, placebo-controlled study. Eligible patients were randomized in a 2:1 ratio to receive Givinostat or placebo for 12 months. Randomization was stratified by concomitant steroid use at baseline (yes or no). The study comprised twelve (12) visits: screening (V1, V2), randomization (V3), treatment (V4-V10), end of study (V11) and follow-up (V12). Visits during treatment took place every 12 weeks, except for the first 2 months, when they occurred every 2 weeks to allow closer monitoring of safety. Givinostat (ITF2357) oral suspension (10 mg/mL) was initially administered as 2 daily doses of 40-70 mg according to body weight after a meal (high dose). With amendment 2 of the protocol, a lower starting dose was implemented to address cases of thrombocytopenia reported following the treatment of the first 21 patients and corresponded to the reduced dose of the original protocol (i.e., 26.7-46.7 mg b.i.d according to body weight, i.e., low dose). 51 patients were to be enrolled to provide a sample size of 48 patients with evaluable baseline biopsies. Seventy patients provided written informed consent, 51 (72.86%) completed screening successfully and were randomized; 34 patients (66.67%) to the Givinostat group and 17 (33.33%) to the placebo group.
