Australia10 participantsStarted 2024-05-01
Plain-language 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

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
