Stopped: Determined priority was to recruit directly to the pivotal Phase III double-blind, placebo-controlled, randomised study (NCT07221292).
This is a multinational, multicenter, open-label, rater-blinded prospective Phase II study which will assess the safety and efficacy of N-Acetyl-L-Leucine (IB1001) for the treatment of Ataxia-Telangiectasia (A-T). There are two phases to this study: the Parent Study, and the Extension Phase. The Parent Study evaluates the safety and efficacy of N-Acetyl-L-Leucine (IB1001) for the symptomatic treatment of A-T. The Extension Phase evaluates the long-term safety and efficacy of IB1001 for the neuroprotective, disease-modifying treatment of A-T.

Clinical Impression of Change in Severity (CI-CS) [Fields et al. 2021]
Timeframe: CI-CS comparing Baseline (Day 1) with IB1001 versus the end of 6-weeks treatment with IB1001 (Approximately Day 42) MINUS the CI-CS comparing the end of 6-weeks treatment with IB1001 (Approximately Day 42) versus the end of 6-weeks post-treatment washout
