Eligibility
Inclusion criteria
Inclusion criteria: •Patients 10 – 16 years of age at time of enrolment •Male •Presence of cardiac involvement/dysfunction, defined by abnormal peak systolic strain in LV inferolateral wall •Confirmed diagnosis of DMD (out of frame dystrophin gene deletion or absent/=65 years) no F.1.3.1 Number of subjects for this age range
Exclusion criteria
Exclusion criteria: •Symptomatic cardiomyopathy or heart failure •Asymptomatic but severe cardiac dysfunction as Screening Visit (( evaluation): FS < 20% and/or EF < 40% •Use of ACE inhibitors •Previous history of ventricular arrhythmias (other than isolated ventricular extrasystole); ventricular arrhythmias presented at Screening •Previous (6 months or less) participation in any other therapeutic trial for DMD •Use of coenzymeQ10, idebenone, creatine, glutamine, oxatomide, or any herbal medicines within the last 6 months •History of significant concomitant illness or significant impairment of renal or hepatic function (serum creatinine and GGT greater than 1.5 times upper limit for age and gender) •Known individual hypersensitivity to idebenone
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To determine whether treatment with idebenone improves or slows decline in cardiac function in patients with cardiac dysfunction associated with DMD;Secondary Objective: To determine whether treatment with idebenone improves or slows decline in muscle strength and/or respiratory function in patients with DMD To evaluate the safety and tolerability of idebenone in patients with DMD To determine whether treatment with idebenone changes biochemical markers reflecting cardiac overload or cardiac degeneration ;Primary end point(s): The relative change from Baseline (at Screening) to Week 52 in peak systolic radial strain of left ventricle (LV) inferolateral wall, assessed by Color Doppler Myocardial imaging (CDMI). | — |
