简要总结
The objective of this study is to determine if citocoline is effective for balance abnormalities and to stabilize cognitive decline in patients with fragile X-associated tremor ataxia syndrome. The study will test 1000mg twice daily of citocoline for 12 months in an open label pilot study, with study visits at baseline, 3, 6, and 12 months.
详细描述
The purpose of this study was to determine if citicoline was safe for the treatment of tremor and balance abnormalities and to stabilize cognitive decline in patients with fragile X-associated tremor ataxia syndrome. Ten participants with diagnosed FXTAS were administered 1000 mg of citicoline once daily for 12 months. Outcome measures and neurological examination were performed at baseline, 3 months, 6 months, and 12 months. The primary outcome was safety. Secondary outcomes included change in FXTAS Rating Scale score, a battery of neuropsychological tests, an instrumented Timed up and go test, computerized dynamic posturography, 9-hole pegboard test, and balance confidence and psychiatric symptom questionnaires.

结局指标
主要结局
FXTAS Rating Scale Score
时间窗: 12 months
The FXTAS Rating Scale (FXTAS-RS), which was designed to measure the severity of motor signs in FXTAS patients, was administered to each participant. The FXTAS-RS was designed to measure the severity of motor signs of FXTAS, tremor, ataxia, and parkinsonism. The scale was developed from a combination of three separate measures: the Clinical Rating Scale for Tremor (CRST), the International Cooperative Ataxia Rating Scale (ICARS), and the Unified Parkinson's Disease Rating Scale (UPDRS). The resultant scale has 44 items and a possible total score of 0-226. A higher score indicates worse symptoms. For this study, improvement was defined as a 20% improvement on the FXTAS-RS.
