Verification of the Efficacy of NPC-15 for Sleep Disorders of Children With Autism Spectrum Disorders (NPC-15-5)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02757066

Brief Summary:
The purpose of this study is to verify the efficacy of NPC-15 (melatonin 1 mg/d or 4 mg/d) versus placebo to sleep latency with electronic sleep diaries.

Condition or disease Intervention/treatment Phase
Sleep Disorders Autism Spectrum Disorder Drug: NPC-15 Granules Lower Dose Drug: NPC-15 Granules Higher Dose Drug: NPC-15 Placebo Granule Phase 2 Phase 3

Detailed Description:
This study will be a multicenter, double-blind, randomized, placebo-controlled parallel group trial. The trial has five phases; the pre-screening phase, the screening phase, double-blinded treatment phase, open label treatment phase and post-treatment phase. The screening phase comprises a screening visit where subject's initial eligibility will be evaluated. During double-blinded treatment phase, patients who meet all entry criteria for the trial will be randomized into three groups, and they will be assigned NPC-15 1 mg, 4 mg or placebo before going to bed for 2 weeks. During open label treatment phase, all patients will be administered NPC-15 1 mg, 2 mg or 4 mg on the basis of their doctors' judgements.

Primary Outcome Measures :
  1. Sleep latency with electronic sleep diary [ Time Frame: Week 2 ]
    Sleep latency is a common endpoint in sleep disorders. In addition, it has been used in a randomized clinical study of sleep disorders of children with neurodevelopmental disorders.

Secondary Outcome Measures :
  1. Sleep latency measured by actigraphy [ Time Frame: Week 2 ]
    To assess the efficacy of this drug in detail

  2. Abnormal behavior checklist Japanese version [ Time Frame: Week 2, 9 ]
    To assess effects of this drug on neurodevelopment disorders

  3. Adverse events [ Time Frame: 10 weeks ]
    To assess safety of this drug

  4. Electro cardiogram [ Time Frame: 10 weeks ]
    To assess safety of this drug
