ABC-CT Pre-School Feasibility Study
Autism Biomarkers Consortium for Clinical Trials (ABC-CT) Pre-School Feasibility Study
Study Overview
Status
Conditions
Detailed Description
The ABC-CT Pre-School Feasibility Study will collect data in a cohort of participants to determine feasibility of the measures used in the ABC-CT Phase 1 study and ABC-CT Confirmation study in 3-5 year old participants. We will be able to examine distributional and psychometric properties of the measures in this group and obtain preliminary estimates of group differences and associations with clinical measures. In addition, we aim to determine the viability of EEG and ET measures as potential biomarkers in 3-5-year-old children with ASD. Viability will be evaluated in terms of (a) valid data acquisition, including adequate levels of participant compliance, (b) reliability of data collection across sites, (c) construct validity in relation to social function, and (d) distributional/psychometric properties.
Primary Objectives:
- To evaluate the feasibility of collecting EEG and ET assessments used in the Phase 1 and Confirmation studies in 3-5 year old.
- To determine the viability of adapted EEG and ET measures as potential biomarkers in 3-5-year-old children with ASD and TD. To further evaluate the psychometric properties of the ET and EEG biomarkers in the 3-5 year old population.
Secondary Objectives:
- To collect blood samples from all ASD subjects and their biological parents for future genomic analyses and to share raw, processed, and analyzed data via the National Database for Autism Research (NDAR) and National Institute of Health / National Institute of Mental Health (NIH/NIMH) Data Repositories to create a community resource accessible for use by all qualified investigators.
- To compare estimates of key distributional parameters across the original, confirmation and feasibility samples to determine whether the markers profiles are sufficiently compatible to use in studies combining pre-school and school-aged children.
The Preschool Feasibility sample will be evenly divided (25 ASD, 25 TD), aged 3-5, with IQ ranging from 60-150, recruited from 5 clinical implementation sites in the US.
Endpoints:
To collect and analyze a new cohort of participants to evaluate the feasibility of ET and EEG acquisition in 3-5 year olds. We will also evaluate ET and EEG measures for potential utility as biomarkers in clinical trials. Primary endpoints include evaluation of (1) Acquisition, (2) Construct Validity, (3) Discriminant Validity.
Primary Biomarker Outcome Variables.
- N170 Latency to Upright Human Faces: The N170 Latency to Upright Human Faces (N170 latency) is a scalp recorded EEG event-related potential (ERP) component elicited by perception of the upright human face. Recorded over the posterior-temporal right hemisphere, the latency (or speed) of the peak of the N170 ERP component occurs at approximately 200 msec in children aged 3 to 5 years of age.
- Oculomotor Index of Gaze to Human Faces (OMI): Onscreen gaze position data, reflected in percentage of foveation (angling of the eyes to focus on a particular object) to human faces (Face%) relative to total valid foveation time across three assays.

Eye-tracking (ET) Static Social Scenes Task
Time Frame: Baseline
|
ET Paradigms will be administered in counterbalanced blocks, one on each day of each screening or study visits.
Both blocks will include all the tasks but in different orders.
The length of individual paradigms ranges from 1 to 8.5 mins.
Color images depicting 12 different female faces with direct gaze and the same faces with averted gaze will be presented.
Twelve different exemplars from each of five categories (alarm clocks, mobile phones, birds, cars, and shoes) will be used as distracters.
Twelve different slides will each contain six images (one face and five distracters, one from each category) placed at an equal distance from the center of the screen.
Each slide contains a different set of six images, each image being shown only once in the experiment.
This measure examines scanning patterns towards arrays of objects, synthetic stimuli, and faces as well as towards more complex naturalistic (static) scenes.
This task examines complex scene processing and attentional selection.

The length of individual paradigms ranges from 1 to 8.5 mins. Pupillary Light Reflex (PLR) Task is measured following a stimuli that consist of a central fixation point on a black background that flashes white for 133 milliseconds. The constriction of the pupil in response to a bright flash indexes function of the parasympathetic nervous system. |

VEPs reflect excitatory (glutamatergic) and inhibitory (GABAergic) activity and may index subgroups of ASD with low-level visual impairments.
VEPs also serve as a control for assessment of higher-order activity in social visual paradigms.
Subjects will be presented with black and white checkerboards that reverse phase at a defined interval.
The order of the VEP and Biomotion paradigms will be counterbalanced.

(CSI-4) is a behavior rating scale for evaluating the symptoms of DSM-IV and DSM-5 emotional and behavioral disorders among children between 5 and 12 years old who are attending elementary school (kindergarten thru 6th grade).
There are both parent- and teacher-completed versions.
The CSI-4: Parent Checklist contains 97 items for over a dozen emotional and behavioral disorders, and the CSI-4: Teacher Checklist contains 77 items.
The CSI-4 can be scored to derive symptom count cutoff scores (diagnostic model) or symptom severity scores (T scores based on a dimensional model).
Scoring is quick and easy with user-friendly score sheets.
