About this study

Official title: Early Identification of Autism Spectrum Disorder: Towards an Integrated Biomarker Approach

This project deals with essential challenges in the context of Autism Spectrum Disorder, benefiting from a longitudinal design in infancy and a cutting-edge electroencephalogram/eye-tracking integrated approach. The investigators will focus on multisensory audiovisual integration to identify early markers of autism in infants at-risk for autism. The investigators will characterize early derailments from the typical developmental trajectories to identify critical "time windows" and better describe the heterogeneity of autism.

Read the detailed description

Autism Spectrum Disorder is a heterogeneous condition characterized by atypical social communication and repetitive patterns of behavior, with recent Italian prevalence estimates of one in 77. The heterogeneity of autism is expressed in individual variation not only in the severity of core symptoms but also in cognitive, language, and behavioral skills, which show different developmental trajectories. Moreover, there is a strong interest in identifying reliable behavioral and brain-based predictors, which may constitute useful tools for early detection of at-risk cases. In particular, autistic individuals perform poorly during conditions that require integration across multiple sensory modalities such as audiovisual sensory integration, and process differently social and non-social stimuli compared to neurotypical counterparts.

However, the study of potential interaction between sensory and social processing in the first years of life is still scarce. No study examined early social and sensory markers in infant siblings of autistic children using integrated experimental techniques.

The study includes siblings of autistic children and neurotypical toddlers recruited at 18 months and a follow-up evaluation is collected at 24 months. At both time-points, all children are assessed with an experimental protocol, including behavioral and neurophysiological measures.

The integrated electroencephalogram -eyetracking task focuses on sensory processing in social (face saying "wow" in infant-directed speech) and non-social (spinning top toy) conditions. Presented videos are presented both in synchronous and asynchronous modalities (1000 ms delay audio presentation). Electroencephalographic signal is recorded by High-Density 128-channel system and pupil dilations are recorded using a Tobii ProSpectrum 300 Hertz system. In addition, complete information about clinical measures is collected for all children at 18 and 24 months.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cognitive outcome of standardized tests

    standardized scores (i.e., Intelligence quotient scores) of Griffiths scales will be measured and will be correlated with electroencephalographic and eyetracking parameters

    Measured: age 36 months

  2. Socio-communicative outcome of standardized tests

    standardized scores (Calibrated severity scores) of Autism Diagnostic Observation Schedule - 2 edition (Social Affect, Restricted/Repetitive behaviors) will be measured and will be correlated with electroencephalographic and eyetracking parameters

    Measured: age 36 months

  3. Sensory outcome of standardized tests

    standardized scores (i.e., z-scores) of sensory profile-2 (sensory seeking, avoiding, sensitivity, registration) will be measured and will be correlated with electroencephalographic and eyetracking parameters

    Measured: age 36 months

  4. Change of electroencephalografic theta power and looking behavior during development

    Electroencephalographic theta power, looking behavior (time of fixation in different areas of interest, pupillometry parameters) to synchronous/asynchronous audio-visual stimuli will be measured longitudinally.

    Measured: at 6, 12, 18 and 24 months

Questions about this trial

What is this clinical trial studying?

An observational study of Autism Spectrum Disorder and Infant Development, run by IRCCS Eugenio Medea at 1 site in Italy.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cognitive outcome of standardized tests (time frame: age 36 months). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Mar 2025.
