About this study

Official title: Transcutaneous Auricular Vagus Nerve Stimulation (taVNS) for the Treatment of Anxiety Comorbid With Autism Spectrum Disorder (ASD)

Investigators will recruit up to 10 patients with Anxiety comorbid with Autism Spectrum Disorder (ASD) from the outpatient clinics at MUSC. This pilot trial will be an open-label investigation of the safety and feasibility of transcutaneous auricular vagus nerve stimulation (taVNS) as a nonpharmacological wearable intervention used to manage anxiety and other neuropsychiatric symptoms at home, with patients/caretakers self-administering treatments. Each subject will undergo an initial in-person screening and be consented prior to participating in the study. This will be followed by an in-person training session with the subject (and caretaker if applicable), where they will learn how to self-administer taVNS and ask any pertinent questions. Participants will self-administer taVNS at home twice daily for 4 weeks. These treatments will not interfere with other aspects of their mental health care. Our investigators, over the prior 8 years, have demonstrated that taVNS is safe and feasible in the outpatient setting. Furthermore, investigators have recently demonstrated that taVNS is well tolerated and safely self-administered at home with remote monitoring. The investigators hypothesize that taVNS will be safe and feasible to administer at home in this new population. Results from this study may lead to further exploration of taVNS in this unique population.

Read the detailed description

This is a research study to find out if anxiety in patients with autism spectrum disorder are affected by a form of ear stimulation called transcutaneous auricular vagus nerve stimulation, or taVNS. Participants will learn how to self-administer ear stimulation treatments at home before starting the study. Over the course of a month, participants will self-administer ear stimulation treatments twice a day for a month. Each treatment will last up to 60 minutes (1 hour) and there will be a break of at least 30 minutes in between treatments. The study team will ask participants to complete a group of questionnaires at the beginning and end of the study. There will also be a smaller number of questionnaires completed electronically on a weekly basis. The questionnaires will ask questions about mental health symptoms that subjects may or may not be experiencing, including questions about mood, anxiety, and sleep.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

    Patients will receive non invasive vagus nerve stimulation via electrodes attached to the ear.

Study groups in NCT06258590
Study groupRoleWhat they receive
tVNSExperimentalAll patients will receive at-home Transcutaneous auricular vagus nerve stimulation (taVNS) and assess the impact on multiple behavioral outcomes associated with ASD and anxiety. This is an open-label trial.
Receives: Device: Transcutaneous auricular vagus nerve stimulation

What is being measured

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

  1. Number of participants experiencing adverse outcomes as measured by questionnaire

    Assessing adverse outcomes via qualitative questionnaire asking participants about experiences during stimulation and any consequences after stimualtion

    Measured: 4 weeks during trial with 30 day follow-up to assess adverse effects

Secondary outcomes (2)
  1. Anxiety rating for participants using generalized anxiety disorder -child scale

    Assessing the impact of stimulation on GAD-child scale, where lower numbers (0=none, 4=extreme) show improved anxiety

    Measured: Testing occurs prior to testing, at two weeks, and following the 4 week trial, along wioth a 30-day post trial follow-up

  2. Empagthic abilities as measured by the Toronto Empathy Questionnaire

    Assessing the participants change in the ability to identify the emotions of others using the TEQ, while a score of less than 45 indicating below average empathy levels, and a max score of 64

    Measured: Testing occurs prior to testing, at two weeks, and following the 4 week trial, along wioth a 30-day post trial follow-up

Questions about this trial

What is this clinical trial studying?

A study testing Transcutaneous auricular vagus nerve stimulation in people with Autism Spectrum Disorder and Anxiety, run by Medical University of South Carolina at 1 site in United States.

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 6 inclusion and 13 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 30 Mar 2026. 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 United States. 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?

Number of participants experiencing adverse outcomes as measured by questionnaire (time frame: 4 weeks during trial with 30 day follow-up to assess adverse effects). 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 30 Mar 2026.
