Status Recruiting

Clinical Trial Summary

This is a randomised, double-blind, placebo-controlled, multicentre study to evaluate the efficacy, safety, and tolerability of givinostat in non-ambulant male paediatric (aged 9 to <18 years) patients with DMD. 138 patients will be randomised 2:1 to givinostat or placebo and will be treated for 18 months. - Planned screening duration: approximately 4 weeks (±14 days) - Planned treatment duration: 18 months (approximately 72 weeks) - Planned follow-up duration: 4 weeks (±7 days) (for patients not participating in the long-term safety study) - Total duration of study participation: up to 83 weeks (ie, 20-21 months)

Clinical Trial Description

Duchenne muscular dystrophy is a rare, progressive, debilitating and life-threatening condition for which there is a critical need for novel therapies that are effective and well-tolerated in all DMD patients. Steroids are generally recognised as the standard of care in the general DMD population; however, they are not suitable for all patients. Givinostat, a HDAC inhibitor, was developed for the treatment of DMD based on: (i) the role that increased HDAC activity is thought to exert in contributing to DMD pathogenesis; and (ii) givinostat's ability to counter the pathophysiological and degenerative mechanisms causing muscle insufficiency in boys with DMD. This study will evaluate the efficacy, safety, and tolerability of givinostat in non-ambulant patients to further corroborate data from the completed phase 3 pivotal study of givinostat in ambulant patients with DMD (ie, Study DSC/14/2357/48, NCT02851797). Primary Objective of the study is to demonstrate the efficacy of givinostat in reducing muscle decline in non-ambulant DMD patients, as measured by Performance of the Upper Limb (PUL) 2.0. Secondary Objectives of the study are to evaluate the safety and tolerability of givinostat in non-ambulant DMD patients, and to further explore the efficacy of givinostat in non-ambulant DMD patients. A total of 138 patients are planned for enrolment. Patients will be randomised 2:1 to givinostat or placebo and will be treated for 18 months. The study will be comprised of: - A screening period, during which eligibility will be confirmed within 4 weeks (±14 days) - A baseline visit, during which randomisation will be performed - A double-blind treatment period, during which patients will receive either givinostat or placebo for 18 months (approximately 72 weeks) - An end of study visit, occurring at Week 72 (±7 days) at the end of the treatment period. At the end of study visit, all the patients (regardless of treatment arm) will be offered enrolment in the long-term safety study DSC/14/2357/51 (NCT03373968) during which they will receive givinostat. - A follow-up visit, for those patients not consenting to participation in the long-term safety study, that will occur 4 weeks after the end of study visit (ie, Week 76 ±7 days). ;
