Ataxia-telangiectasia: Treating Mitochondrial Dysfunction With Nicotinamide Riboside

Summary

Study design: Single arm open-label clinical trial in ataxia-telangiectasia to test the effects of nicotinamide riboside on ataxia scales, immune function, and neurofilament light chain. Study population: 6-10 patients with Ataxia-Telangiectasia. Dose: Nicotinamide riboside 25 mg/kg/day in 3 equal divided doses. Primary endpoint: Scales for assessment and rating of ataxia (SARA), and International Cooperative Ataxia Rating Scale (ICARS). Improvement of at least ½ standard deviation in key clinical scales which includes either; a) significant improvement in total combined scores from the SARA and ICARS scales, and /or b) significant improvements any aspects of the SARA and ICARS scales individually, especially pertaining to; Postural and gait improvements, Improved syllable speed and articulation, Improved fine motor skills. Secondary endpoints: Serum analysis of neurofilament light chain (Nfl), Type 1 Interferon (INFs) epigenetic signature
