Study of N-acetyl-L-leucine for CACNA1A Disorders
This study is testing N-acetyl-L-leucine (a modified amino acid) in people aged 4 and older with a genetically confirmed CACNA1A disorder, which includes conditions like Spinocerebellar Ataxia Type 6, Episodic Ataxia Type 2, and Familial Hemiplegic Migraine-1. The goal is to see if N-acetyl-L-leucine is safe and effective compared to a placebo (an inactive substance). Researchers will measure changes in ataxia (problems with coordination and balance) using a special scale over 24 weeks. This study is currently unclear regarding its recruitment status, but plans to enroll 60 participants.
- Study design
- This is a randomized, double-blind, placebo-controlled study where participants will receive N-acetyl-L-leucine and a placebo at different times. It is a multinational, cross-over Phase III study.
- What's involved
- You will participate in a baseline period of about 2 weeks, followed by two 12-week treatment periods where you will receive either N-acetyl-L-leucine or placebo. You will be assessed twice during each study period.
- Compensation
- Not stated in the trial record.
- Follow-up
- After the main study, participants may be offered the chance to join an Extension Phase to continue receiving N-acetyl-L-leucine.

What this trial measures
- Scale for the Assessment and Rating of AtaxiaEnd of Period I (week 12) vs. End of Period 2 (week 24)
The Scale for Assessment and Rating of Ataxia has 8 items that are related to gait, stance, sitting, speech, finger-chase test, nose-finger test, fast alternating movements, and heel-shin test. The range is 0-40 points, with a lower score representing neurological improvement and a higher score representing neurological worsening.
