About this study

Retrospective case-control study to assess the diagnostic accuracy in autism spectrum disorder (ASD) of a new smartphone-based platform designed to conduct neurometric evaluations by measuring facial and behavioural reflexes.

Read the detailed description

This is a retrospective multi-centre case-control study to measure sensorimotor anomalies linked to autism spectrum disorder (ASD) to assess the diagnostic accuracy of smartphone-based neurobehavioral evaluations. The primary objective of the study is to evaluate diagnostic accuracy of the smartphone-based assessments compared to a formal clinical diagnosis using machine learning algorithms.

Neurobehavioral testing will be performed using BlinkLab, a smartphone-based platform. The tests include general measurement of spontaneous and stimulus-evoked postural, head, facial, and vocal responses along with specific neurometric tests, including the acoustically evoked eyelid startle reflex (ASR), and tests that involve the modulation of the ASR, including prepulse inhibition (PPI) and habituation (HAB). Children required to participate in two consecutive 15-minute tests. During the experiment, the children will watch an audio-normalized movie while the trials containing the auditory stimuli will be delivered via headphones. For each trial, computer vision algorithms will be used to track and record the position of the participant's facial landmarks over time. The study will compare responses in children with ASD who received a formal DSM-5 based diagnosis prior to study inclusion and neurotypical children that had no formal psychiatric diagnoses.

What is being measured

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

  1. Device Sensitivity

    Measure of the proportion of children truly having ASD who are correctly identified by the device as Positive for ASD relative to a formal DSM-5 diagnosis

    Measured: at baseline

  2. Device Specificity

    Measure of the proportion of children truly not having ASD (who had no prior psychiatric diagnosis) who are correctly identified by the device as Negative for ASD

    Measured: at baseline

Secondary outcomes (11)
  1. Screen Avoidance

    The percentage of trials wherein the child was avoiding the smartphone's screen and camera

    Measured: at baseline

  2. Anteroposterior Postural Stability

    The child's anteroposterior postural stability

    Measured: at baseline

  3. Head Rotations

    The percentage of trials wherein the child was rotating their head

    Measured: at baseline

  4. Headphone Touches

    The percentage of trials wherein the child was touching the headphone

    Measured: at baseline

  5. Mouth Opening

    The size and timing of the child's mouth openings and closings

    Measured: at baseline

  6. Vocalizations

    The percentage of trials wherein the child was vocalizing and the corresponding time of occurrence

    Measured: at baseline

  7. Acoustic Startle Response (ASR)

    Difference in the amplitude of the eyelid ASR between the ASD and neurotypical children

    Measured: at baseline

  8. Long-term habituation (long-term HAB)

    Levels of habituation of the ASR over the course of the 15-minute test

    Measured: at baseline

  9. Prepulse inhibition (PPI)

    Reduction in the amplitude of the eyelid startle response due to prepulse stimuli

    Measured: at baseline

  10. Short-term habituation (short-term HAB)

    Habituation in the mean amplitude of eyelid startle responses over the course of the six startle pulses

    Measured: at baseline

  11. Anticipatory eye blinks (AEB)

    The anticipatory eye blinks (AEB) in predefined observation windows (OW) containing an omitted pulse. AEB were responses that were not triggered by the startle stimulus itself but rather by the expectation of an upcoming startle stimulus

    Measured: at baseline

Questions about this trial

What is this clinical trial studying?

A study testing Blinklab diagnostic device in people with Autism Spectrum Disorder, run by Blinklab Limited at 1 site in Morocco.

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 4 inclusion and 3 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: status not confirmed, as of the sponsor's last update on 12 Jul 2024. 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 Morocco. 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?

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

Contact Henk-Jan Boele, MD (+31611132247, henkjan@blinklab.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Device Sensitivity (time frame: at baseline). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06497218, which also lists 1 linked publication.

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 12 Jul 2024.
