LEROS is an open-label interventional Phase IV study, designed to further assess the efficacy and safety of Raxone® in the long-term treatment of LHON patients.
Name: Idebenone
Type: DrugRaxone
Description: Proportion of eyes with clinically relevant recovery of visual acuity (VA) from Baseline or in which Baseline VA better than 1.0 logMAR was maintained at Month 12 in patients treated with Raxone® ≤1 year after the onset of symptoms, compared to matching external natural history control group
Measure: Proportion of eyes with clinically relevant recovery of visual acuity from Baseline Time: 12 monthsSingle Group Assignment
There are 3 SNPs
