Summary

This is an outpatient, multicenter, prospective, pivotal, double-blind, within-subject comparison trial of the Marcus Autism Center Investigational Device (MAC-ID) diagnostic procedure relative to the gold-standard (reference standard), current best practice expert clinician diagnosis (ECD) of Autism Spectrum Disorder (ASD) in children 16-30 months of age. Consecutive pediatric patients from the intended population (i.e. children 16-30 months of age) recruited from pediatric referrals and general advertisements will be the subjects of this trial. All subjects will undergo the MAC-ID diagnostic procedure (test). All subjects will also undergo the current best practice clinical diagnostic procedure, using standardized ASD diagnostic instruments and standardized developmental assessments, to produce the ECD of each child's ASD status (reference/gold standard). The study consists of a screening phase and diagnostic evaluation phase to assess the validity (sensitivity and specificity), safety, and effectiveness of the MAC-ID when used to diagnose ASD. Subjects will be enrolled in the trial for a period of 1 day. The trial will be completed in approximately 12 months. The overall study objective is to assess the safety and effectiveness of the MAC-ID to accurately diagnose ASD (primary analysis), as well as to accurately assess severity of ASD (secondary analysis) in very young pediatric subjects. The primary endpoints of this study are the diagnostic result from the MAC-ID and the diagnostic results from the ECD evaluation, both of which are either positive or negative for ASD. Each subject will undergo the Social Developmental Testing Device procedure and an examination by a clinical expert in the field of ASD diagnosis; all study center site personnel (including the expert clinicians responsible for the ECD evaluation) will be blinded to MAC-ID results.

Interventions

Type	Name	Description
DEVICE	Marcus Autism Center Investigational Device	This trial will ascertain whether the binary results of autism or not-autism as determined by the Marcus Autism Center Investigational Device match expert clinical diagnostic opinion. The investigational device is designed to measure visual attention to social information in the environment relative to normative, age-specific benchmarks; these measurements assess presence (primary efficacy outcome) and severity (secondary outcomes) of autism spectrum disorder in 16- to 30-month-old children.
