Clinical Trial Summary

This is a randomized placebo controlled study in children diagnosed with autism spectrum disorder (ASD), to Investigate the Efficacy and Safety of Slenyto® to alleviate Sleep Disturbances in these children. . The main objective is to compare treatment effect of Slenyto® 2 mg or 5 mg to that of placebo on sleep duration (total sleep time [TST]) as assessed by the Sleep and Nap Diary after 3 weeks of double blind treatment.

Description:

This is a randomized placebo controlled study in children diagnosed with autism spectrum disorder (ASD). Children will have a documented history of this disorder, as confirmed or consistent with the International Classification of Diseases (ICD 10) or Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (Text Revision; DSM 5) criteria, having DSM-5 criteria based sleep disturbances at screening. The children will undergo 4 weeks of basic sleep hygiene and behavioral intervention, which will serve as a wash out period from any hypnotics and prohibited medications; Children with a documented history of sleep hygiene and behavioral intervention who are taking a prohibited medication will not require additional training and will undergo a 2-week wash out period before Visit 1. Children who are still found to be eligible for the study after the 4 week, basic sleep hygiene and behavioral intervention wash out period, will continue in a 2 week single blind (SB) placebo run in period. . After the 2 week SB placebo run in period (Visit 2; Week 2), children who are still found eligible for study participation will be randomized in a 1:1 ratio to receive either Slenyto® (1 or 5 mg prolonged release melatonin tablets) or placebo for 3 weeks double-blind treatment period. The starting dose will be 2X1mg Slenyto® or matching placebo. During these 3 weeks parents will complete the electronic sleep and nap diary every morning. After one week of double-blind treatment, on the last day of Week 3 ±3 days (Visit 3), sleep variables will be assessed to determine if dose modification (increase to 1X5 mg Slenyto® or matching placebo) is required. Children will then continue on 2 or 5 mg of Slenyto® or matching placebo to the end of the double blind period (End-of Study Visit 4; Week 5). Study duration will be either 5, 7, or 9 weeks, including the optional 2-weeks medication wash out and 4 weeks sleep hygiene and behavioral intervention periods (overlapping). The main objective is to compare treatment effect of Slenyto® 2 mg or 5 mg to that of placebo on sleep duration (total sleep time [TST]) as assessed by the Sleep and Nap Diary after 3 weeks of double blind treatment. The key secondary endpoints are SL and LSE. Safety will also be assessed by Adverse events, vital signs and physical examination.

Eligibility

Inclusion Criteria:

• children 2 to 17.5 years of age at Visit 2 who comply with taking the study drug
• Written informed consent provided by a legal guardian and assent (if needed)
• A documented history of ASD according to or consistent with the ICD 10 or DSM 5 criteria, as confirmed by case note review showing that diagnosis was reached through assessment by a community pediatrician or pediatric neurologist or other health care professionals experienced in the diagnosis who took into account early developmental history and school records.
• Current sleep problems consistent with DSM-5 criteria including: a minimum of 3 months of impaired sleep defined as =6 hours of continuous sleep AND = 0.5-hour sleep latency from light off in 3 out of 5 nights based on parent reports and subject medical history. (The maintenance and latency problems do not necessarily have to be in the same 3 nights of the week.)
• May be on a stable dose of non excluded medication for 3 months, including anti epileptics, anti depressants (selective serotonin reuptake inhibitor [SSRIs]), and ß blockers. (Only morning administration of ß blockers is allowed since ß blockers at night have the potential to reduce endogenous
• The sleep disturbance is not due to the direct physiological effects of any concomitant medications such as SSRIs, ß blockers etc.

Exclusion Criteria:

• Have had treatment with any form of melatonin within 2 weeks prior to Visit
• Have a known allergy to melatonin or lactose
• Have a known moderate to severe sleep apnea
• Have an untreated medical/ineffectively treated/psychological condition that may be the etiology of sleep disturbances
• Are taking or have been taking prohibited medication within 2 weeks prior to Visit 1
• Are females of child bearing potential that are not using contraceptives and/or breastfeeding and that are sexually active (Abstinence is an acceptable method of contraception.)
• Pregnant females
• Are currently participating in a clinical trial or have participated in a clinical trial involving medicinal product within the last 3 months prior to the study
• Participated in Study NEU_CH_7911
• Children with known renal or hepatic insufficiency
