High-dose pharmaceutical grade biotin (MD1003) in amyotrophic lateral sclerosis: A pilot study.

ABSTRACT: Background:Oligodendrocytes (OGs) provide metabolic support to motor neurons (MNs) and are implicated in the pathophysiology of amyotrophic lateral sclerosis (ALS). MD1003, or high-dose Pharmaceutical grade Biotin (hdPB), may improve disability in progressive multiple sclerosis patients via augmentation of OG or MN energy levels. Here, we assessed the safety and efficacy of MD1003 in ALS patients. Methods:This single centre, randomised, double-blind, placebo-controlled trial included patients aged 25-80 years with probable or definite ALS. Patients were assigned (2:1), using a computer-generated randomisation list, to receive oral MD1003 (300 mg/day) or placebo treatment for 24 weeks. The primary outcome, safety, was analysed in all patients who received at least one dose of study drug. This study, registered with ClinicalTrials.gov, NCT03114215, has been completed. Findings:Between June and December 2016, 30 patients were enrolled (MD1003, n = 20; placebo, n = 10). Baseline characteristics were representative of the ALS population. MD1003 and placebo groups were not well balanced at screening, with the MD1003-treated group having a higher rate of ALSFRS-R decline prior to screening versus placebo (-6·0 IQR [-8·5, -5·0] vs. -5·0 IQR [-5·0, -3·0]) and a predominance of ALS with upper limb onset compared to placebo (35% vs. 10%). MD1003 had a favourable safety profile and was well tolerated. The occurrence of adverse events was similar in both groups (60%). Two deaths occurred in the MD1003 group versus 1 in the placebo group. ALSFRS-R median change from baseline to month 6 was not significantly different between the two groups (p = 0·49); the mean difference between groups was -1·6 (SEM=3·3). Interpretation:MD1003 treatment was safe and well tolerated. It was not possible to establish MD1003 efficacy in this relatively small study. Given the favourable safety profile of MD1003 and an imbalance between treatment groups favouring placebo, additional, larger studies in ALS are warranted. Funding:MedDay Pharmaceuticals.

Project description:BACKGROUND:Chronic visual loss is a disabling feature in patients with multiple sclerosis (MS). It was recently shown that MD1003 (high-dose pharmaceutical-grade biotin or hdPB) may improve disability in patients with progressive MS. OBJECTIVE:The aim of this study was to evaluate whether MD1003 improves vision compared with placebo in MS patients with chronic visual loss. METHODS:The MS-ON was a 6-month, randomized, double-blind, placebo-controlled study with a 6-month open-label extension phase. Adult patients with MS-related chronic visual loss of at least one eye [visual acuity (VA) below 0.5 decimal chart] were randomized 2:1 to oral MD1003 300 mg/day or placebo. The selected eye had to show worsening of VA within the past 3 years following either acute optic neuritis (AON) or slowly progressive optic neuropathy (PON). The primary endpoint was the mean change from baseline to month 6 in VA measured in logarithm of the minimum angle of resolution (logMAR) at 100% contrast of the selected eye. Visually evoked potentials, visual field, retinal nerve fiber layer (RNFL) thickness, and health outcomes were also assessed. RESULTS:Ninety-three patients received MD1003 (n = 65) or placebo (n = 28). The study did not meet its primary endpoint, as the mean change in the primary endpoint was nonsignificantly larger (p = 0.66) with MD1003 (- 0.061 logMAR, + 3.1 letters) than with placebo (- 0.036 logMAR, + 1.8 letters). Pre-planned subgroup analyses showed that 100% contrast VA improved by a mean of + 2.8 letters (- 0.058 logMAR) with MD1003 and worsened by - 1.5 letters (+ 0.029 logMAR) with placebo (p = 0.45) in the subgroup of patients with PON. MD1003-treated patients also had nonsignificant improvement in logMAR at 5% contrast and in RNFL thickness and health outcome scores when compared with placebo-treated patients. There was no superiority of MD1003 vs placebo in patients with AON. The safety profile of MD1003 was similar to that of placebo. CONCLUSIONS:MD1003 did not significantly improve VA compared with placebo in patients with MS experiencing chronic visual loss. An interesting trend favoring MD1003 was observed in the subgroup of patients with PON. Treatment was overall well tolerated. TRIAL REGISTRATION:EudraCT identifier 2013-002112-27.
