About this study

Official title: A Multidisciplinary Translational Approach to Investigate the Mechanisms, Predictors, and Prevention of Persistent Post-Traumatic Headache - Human Studies Protocol: Individual Projects Excluding Clinical Trial

This is a United States Department of Defense funded Focused Program study that aims to identify mechanisms and predictors for persistent of post-traumatic headache attributed to mild traumatic brain injury, and identify methods of preventing post-traumatic headache persistence

Read the detailed description

The human studies component of this Focused Program include clinical phenotyping, neurophysiology, molecular and genetic biomarker discovery, and brain imaging. This data will be utilized to characterize post-traumatic headache and build univariate and multivariate predictive models for post-traumatic headache persistence and for the response to post-traumatic headache treatment. Some participants might be eligible to participate in the clinical trial portion of this study.The clinical trial is a double-blind, randomized, placebo-controlled investigation of erenumab for the treatment of post-traumatic headache. Participants will be randomized when PTH has been present for 35-56 days. The clinical trial component of this Focused Program is described in more detail in a separate clinicaltrials.gov record.

Follow-up questionnaires, headache diary data, pain threshold results, and brain imaging data will be collected longitudinally during the trial to assess for changes over time and associations of such changes with post-traumatic headache treatment outcomes.

Study groupRoleWhat they receive
Post-Traumatic HeadacheIndividuals who have post-traumatic headache attributed to mild traumatic brain injury according to ICHD-3 diagnostic criteria
Healthy ControlHealthy controls will have no history of traumatic brain injury and no history of migraine or other headaches

What is being measured

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

  1. Longitudinal Assessment of PTH Phenotype

    descriptive analysis of post-traumatic headache characteristics such as headache frequency and severity, and characteristics of associated conditions such as symptoms of sensory hypersensitivities, anxiety, depression, insomnia, autonomic dysfunction, and cognitive function

    Measured: baseline with longitudinal follow-up at weeks four and sixteen

  2. Longitudinal Assessment of Cutaneous Pain Thresholds

    heat pain thresholds on the skin determined by quantitative sensory testing

    Measured: baseline with longitudinal follow-up at weeks four and sixteen

  3. Longitudinal Assessment of Visual Pain Thresholds from Bright Light Exposure

    visual pain thresholds to different light intensities

    Measured: baseline with longitudinal follow-up at weeks four and sixteen

  4. Longitudinal Assessment of Brain MRI

    structural brain imaging to include measures such as cortical thickness, regional volumes, brain curvature, white matter tract integrity, and functional brain imaging measures such as resting state functional connectivity and pain-induced brain activation

    Measured: baseline with longitudinal follow-up at weeks four and sixteen

  5. Longitudinal Assessment of Blood Based Biomarkers

    blood-based biomarkers, including DNA and targeted serum proteins, associated with acute and persistent post-traumatic headache and response to therapy

    Measured: baseline with longitudinal follow-up at weeks four and sixteen

  6. Longitudinal Assessment of Post-traumatic Headache Biomarkers

    clinical characteristics, pain thresholds, and brain imaging features as described above that are associated with acute post-traumatic headache and persistent post-traumatic headache; that predict the persistent of post-traumatic headache; and that predict and measure treatment response

    Measured: baseline with longitudinal follow-up at weeks four and sixteen

Questions about this trial

What is this clinical trial studying?

An observational study of Post-Traumatic Headache, run by Mayo Clinic at 5 sites 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 7 inclusion and 61 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 12 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites 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?

Longitudinal Assessment of PTH Phenotype (time frame: baseline with longitudinal follow-up at weeks four and sixteen). The study lists 6 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 12 Sep 2025.
