Registered outcomes2

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryReduction in Respiratory Abnormality in Patients With Rett SyndromeBaseline up to week 24
Measured as the percent change in the number of apnea episodes per hour during awake time, calculated using an ambulatory data acquisition system (BioRadioTM) as part of home monitoring procedure. BioRadioTM record specific respiratory and cardiac parameters.
SecondaryEfficacy of Sarizotan Assessed by the Caregiver-rated Impression of Change24 weeks
Caregiver-rated Impression of Change (CIC): 7-point scale requiring the caregiver to rate how much the patient's illness has improved or worsened relative to the baseline state. 7-point Likert-type scale for which ratings range from 1 = very much improved to 7 = very much worse, with 4 = no change. This caregiver-rated measure considered activities, behavior, mood and functioning. This rating was performed in consultation with the study Investigator but was based largely on the caregivers' evaluation during the reporting period. The single rating of the CIC was to be based on changes in the following domains: • Activities (watching TV, interest in conversations around her, cooperation during toileting, dressing/bathing, etc.), • Communication (verbal or by eye movements, hand movements, or head movements), • Behavior (agitation, refusal to feed, scratching, social avoidance), • Participation in family/outdoor/social events)
