If total IQ score is unconclusive due to heterogenicity of sub-scores, participant should have at minimum both sub-scores for verbal comprehension and perceptual reasoning ≥
- •Social Responsiveness Scale Second Edition (SRS-2) total T-score ≥ 66 at screening and baseline.
- •All ongoing medications or interventions (except those listed as prohibited in “previous and concomitant medications/therapy” section) for ASD related symptoms must have been stable for at least 4 weeks prior to screening, and the participant/caregiver must be willing to maintain a stable regimen throughout the study.
- •Participants’ language, hearing and vision must be compatible with the study assessments as judged by the investigator.
- •Participants must have the ability to swallow the investigational medicinal product (IMP).
排除标准
- •Known hypersensitivity to the investigational medicinal product including active substance and excipients.
- •Participants with clinically relevant abnormal laboratory values suggesting an unknown disease and requiring further clinical investigation per investigator judgement.

- •Participants taking part in another interventional study and/or the use of any investigational therapy within the 30 days prior to screening.

- •Participant with a history of suicidal behavior or suicidal ideation in the past 12 months, or a positive answer to questions 4 or 5 on the Columbia-Suicide-Severity Rating Scale (C-SSRS) at screening and/or baseline, and/or is a significant risk for suicidal behavior per investigator judgement.
- •Participants with cardiac disorders including clinically significant deviation from normal on 12-lead ECG that results as per investigator judgement in an active medical problem, or with a QTcF > 450ms at screening, where they are co-medicated or not with QT-prolonging medicinal products or medicinal products known to increase the risk of repolarization disorders.
