About this study

Official title: A Randomized, Single-Center, Double-Blind, Parallel, Sham-Controlled Study of Gammacore Sapphire (Non-Invasive Vagus Nerve Stimulator) for the Acute and Preventive Treatment of Post-Traumatic Headache (GAP-PTH)

The purpose of this single-center, prospective, randomized, double-blind, sham controlled, parallel-group study is to collect clinical data related to the safety and efficacy of vagus nerve stimulation for the acute and preventive treatment of Post Traumatic Headache.

Read the detailed description

The study will enroll 60 subjects over a period of 14 weeks each. Subjects will use either a sham or active device to treat acute Post Traumatic Headache. Investigators will collect clinical data related to the use of the device.

Being tested
gammaCore Sapphire, sham gammaCore Sapphire

What is being measured

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

  1. Relief of Post Traumatic Headache

    Decrease in pain between active and sham treatment groups between the baseline assessment and 60 minutes post-treatment on a subset of questions from the Sport Concussion Assessment Tool, 5th edition (SCAT5) Graded Symptom Checklist

    Measured: Over 14 weeks

Secondary outcomes (1)
  1. Decrease in Pain

    • Decrease in pain (based on the 7-point NRS) at 30 and 120 minutes after initial treatment, for all treated attacks in the nVNS and sham treatment groups

    Measured: Over 14 weeks

Questions about this trial

What is this clinical trial studying?

A study testing gammaCore Sapphire in people with Post-Traumatic Headache, run by University of Texas Southwestern Medical Center 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 4 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The record says: withdrawn, as of the sponsor's last update on 10 Mar 2020. 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. Some participants in this study may receive a placebo. 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 was withdrawn before enrolling participants, so there are no results.

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?

Relief of Post Traumatic Headache (time frame: Over 14 weeks). 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 NCT04071743, which also lists 26 linked publications.

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 10 Mar 2020.
