结局指标
主要结局
Rett Syndrome Behavior Questionnaire (RSBQ) Total Score - Change From Baseline to Week 12
时间窗: Baseline and Week 12
The RSBQ is a 45-item caregiver-completed rating scale that includes 45 items, 39 of them grouped into 8 subscales, whose ratings reflect the severity and frequency of symptoms. Items are rated as 0 (not true), 1 (somewhat or sometimes true), or 2 (very true). The 8 subscales are general mood, breathing problems, hand behavior, face movements, body rocking/expressionless face, night-time behaviors, fear/anxiety, and walking/standing. Scores for item 31 are reversed in the calculation of the total score. The total score ranges from 0 to 90 and is calculated as the sum of the item scores. Higher scores mean worse behavior.
Clinical Global Impression-Improvement (CGI-I) Score at Week 12
时间窗: 12 Weeks Treatment Duration
To rate how much the subject's illness has improved or worsened relative to a baseline state, a 7-point scale is used from 1=very much improved, 2=much improved, 3=minimally improved, 4=no change, 5=minimally worse, 6=much worse, 7=very much worse.
