The purpose of this study is to establish the efficacy and safety of Circadin in children with neurodevelopmental disorders and to determine the dose, this randomized, placebo-controlled study is planned to evaluate the efficacy of a double-blind, 13 week treatment period with Circadin 2/5mg in improving maintenance of sleep, sleep latency and additional parameters in children with neurodevelopmental disabilities. The efficacy and safety of Circadin 2/5 mg will continue to be assessed during an open-label extension period of 13 weeks.

Primary Outcome Measures:
  • The total sleep time will be measured for the Circadin 2/5 mg and placebo by a Sleep and nap diary questionnaire after the 13 week, double-blind treatment period. [ Time Frame: up to 1.5 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Sleep latency will be measured for the Circadin 2/5 mg and placebo by a Sleep and Nap Diary after 13 weeks of double-blind treatment. [ Time Frame: up to 1.5 years ] [ Designated as safety issue: No ]

  • The duration of wake after sleep onset period will be measured for the Circadin 2/5 mg and placebo by a Sleep and Nap Diary after 13 weeks of double-blind treatment. [ Time Frame: up to 1.5 years ] [ Designated as safety issue: No ]

  • The number of awakenings during the night will be measured for the Circadin 2/5 mg and placebo by a Sleep and Nap Diary after 13 weeks of double-blind treatment. [ Time Frame: up to 1.5 years ] [ Designated as safety issue: No ]

  • The duration of the longest sleep period will be measured for the Circadin 2/5 mg and placebo by a Sleep and Nap Diary after 13 weeks of double-blind treatment. [ Time Frame: up to 1.5 Years ] [ Designated as safety issue: No ]

  • The children's social functioning at home, in school, and community settings will be measured for the Circadin 2/5 mg and placebo by the Children Global Assessment Scale (CGAS) Questionnaire after 13 weeks of double-blind treatment. [ Time Frame: up to 1.5 years ] [ Designated as safety issue: No ]

  • The children's behavior at home, in school, and community will be measured for the Circadin 2/5 mg and placebo by the Strength of Difficulties Questionnaire (SDQ) Questionnaire filled out by the parents after 13 weeks of double-blind treatment. [ Time Frame: up to 1.5 years ] [ Designated as safety issue: No ]

  • The number of dropouts between Circadin 2/5 mg to that of placebo will be compared during the 13 weeks of double-blind treatment. [ Time Frame: up to 1.5 years ] [ Designated as safety issue: No ]
  • Sleep parameters (rest/activity cycles) will be measured for the Circadin 2/5 mg and placebo as measured by actigraphy after 13 weeks of double-blind treatment. [ Time Frame: up to 1.5 years ] [ Designated as safety issue: No ]
    The Actigraph will be worn on the wrist at night and collect the Sleep parameters

  • Safety and tolerability throughout the study will be measured for the Circadin 2/5 mg and placebo throughout the study using AE eliciting method Treatment Emergent Signs and Symptoms (TESS) [ Time Frame: up to 2.5 years ] [ Designated as safety issue: Yes ]

  • The following Vital Signs will be measured: blood pressure, pulse, breathing and body temperature. They will be compared between the Circadin and placebo groups. [ Time Frame: up to 2.5 years ] [ Designated as safety issue: Yes ]

  3. Must have a documented history of ASD according to ICD-10 or DSM-5 or neurodevelopmental disabilities caused by neurogenetic diseases (Smith-Magenis syndrome [SMS], Angelman syndrome, Bourneville's disease [tuberous sclerosis]) as confirmed by case note review showing that diagnosis was reached through assessment by a community paediatrician or paediatric neurologist, who took into account early developmental history and school records.
  4. Must have current sleep problems including: A minimum of 3 months of impaired sleep defined as <6 hours of continuous sleep with more than 0.5 hour sleep latency from light off in 3 out of 5 nights.
