Outcome Measures

Primary Outcomes (1)

  • Efficacy on autism spectrum social core symptom assessed by social reciprocity score on the Autism Diagnostic Observation Schedule module 4

    Changes in social reciprocity score (range: 0-14, Higher value represent a worth outcome) on Autism Diagnostic Observation Schedule module 4 between baseline and endpoint of each administration period

    At baseline, which was before and on the same day as the first administration, and at endpoint, which was started approximately 15 min after the last drug administration

Secondary Outcomes (9)

  • Efficacy on autism spectrum core symptom assessed by communication score on the Autism Diagnostic Observation Schedule module 4

    At baseline, which was before and on the same day as the first administration, and at endpoint, which was started approximately 15 min after the last drug administration

  • Efficacy on autism spectrum core symptom assessed by repetitive and restricted behavior score on the Autism Diagnostic Observation Schedule module 4

    At baseline, which was before and on the same day as the first administration, and at endpoint, which was started approximately 15 min after the last drug administration

  • Efficacy on autism spectrum core symptom assessed by revised algorithm score of social affect on the Autism Diagnostic Observation Schedule module 4

    At baseline, which was before and on the same day as the first administration, and at endpoint, which was started approximately 15 min after the last drug administration

  • Efficacy on autism spectrum core symptom assessed by revised algorithm of repetitive and restricted behavior score on the Autism Diagnostic Observation Schedule module 4

    At baseline, which was before and on the same day as the first administration, and at endpoint, which was started approximately 15 min after the last drug administration

  • Efficacy assessed by Clinical Global Impression-Improvement

    At baseline, which was before and on the same day as the first administration, and at endpoint, which was assessed within 100 min after the last drug administration

  • +4 more secondary outcomes
