Important Notes:
The effectiveness and safety of DAYBUE were evaluated in the 12-week LAVENDER™ clinical trial of 187 female patients aged 5 to 20 with Rett syndrome. DAYBUE was shown to significantly reduce the severity in signs and symptoms of Rett syndrome as measured by the Rett Syndrome Behaviour Questionnaire (RSBQ) compared to placebo. RSBQ assessed the following signs and symptoms: breathing, hand movements or stereotypies, repetitive behaviors, nighttime behaviors, vocalizations, facial expressions, eye gaze, and mood
Because everyone with Rett syndrome is unique—with a unique set of symptoms—the response to DAYBUE may be different for each individual. Always speak with a healthcare provider to learn what to expect when starting DAYBUE, including side effects
