About this study

Official title: A Multidisciplinary Translational Approach to Investigate the Mechanisms, Predictors, and Prevention of Persistent Post-Traumatic Headache

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.

The objective of the clinical trial component of the Focused Program is to determine whether intervention with erenumab is an effective treatment for PTH attributed to mTBI.

Read the detailed description

The human studies component of this Focused Program includes clinical phenotyping, neurophysiology, molecular and genetic biomarker discovery, brain imaging, and a clinical trial.These 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. These studies are described in more detail within a separate clinicaltrials.gov record.

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. Follow-up questionnaires, headache diary data, pain threshold results, and brain imaging data will be collected longitudinally during the clinical trial to assess for changes over time and associations of such changes with post-traumatic headache treatment outcomes. Due to slow enrollment, the study was later changed to open label since the estimated total enrollment would be inadequate for making comparisons between the placebo and erenumab groups.

What is being measured

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

  1. Change in the Number of Days Experiencing Moderate-to-Severe Headaches

    The number of days where subjects experienced moderate-to-severe headaches. This was measured at baseline, 9, 10, 11 and 12 weeks after administration of first dose of erenumab 140 mg or placebo. The change from baseline to week 12 is reported.

    Measured: Baseline, 9, 10, 11 and 12 Weeks, change from baseline to week 12 reported

Secondary outcomes (4)
  1. Responder Rate

    The number of patients with at least a 50% reduction in days where they experienced a headache. This was measured at baseline, 9, 10, 11 and 12 weeks after administration of first dose of erenumab 140 mg or placebo. The change from baseline to week 12 is reported.

    Measured: Baseline, 9, 10, 11 and 12 Weeks, change from baseline to week 12 reported

  2. Chronic Headache

    The number of patients with a chronic headache, defined as reporting a headache for at least 15 days. This was measured at baseline, 9, 10, 11 and 12 weeks after administration of first dose of erenumab 140 mg or placebo. The change from baseline to week 12 is reported.

    Measured: Baseline, 9, 10, 11 and 12 Weeks, change from baseline to week 12 reported

  3. Change in the Headache Impact Test (HIT-6)

    The Headache Impact Test (HIT-6) measures the impact of headaches on a person's daily life. It assesses the frequency and severity of headaches, their functional limitations and the impact on daily activities such as work, education and social interactions. The HIT-6 test has 6 questions. Each of the six questions receives a score from 6-13. The final HIT-6 score can range from 36 to 78. A higher score indicates more disability due to headache. This was measured at baseline, 9, 10, 11 and 12 weeks after administration of first dose of erenumab 140 mg or placebo. The change from baseline to week 12 is reported.

    Measured: Baseline, 9, 10, 11 and 12 Weeks, change from baseline to week 12 reported

  4. Change in the Number of Days Where Acute Treatment Was Administered to Relieve a Headache

    The change in the number of days where subjects underwent acute treatment to relieve a headache. Treatment days were days in which subjects took analgesic, triptan, or ergotamine containing medication, or they underwent device neuromodulation [e.g. vagal or trigeminal nerve electrical stimulation or single pulse transcranial magnetic stimulation]. This was measured at baseline,9, 10, 11 and 12 weeks after administration of first dose of erenumab 140mg or placebo. The change from baseline to 12 weeks is reported.

    Measured: Baseline, 9, 10, 11 and 12 Weeks, change from baseline to week 12 reported

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Erenumab in people with 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 8 inclusion and 40 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 23 Oct 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. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 23 Oct 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Change in the Number of Days Experiencing Moderate-to-Severe Headaches (time frame: Baseline, 9, 10, 11 and 12 Weeks, change from baseline to week 12 reported). 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 23 Oct 2025.
