Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

Study population: All patients seen in the local headache clinic are screened for eligibility to participate the study. Clinical routine is not influenced by participation in this observational study, importantly choice of prophylactic treatment solely depends on the physician's and patient's decision based on national guidelines.

  • episodic migraine according to ICHD (international classification of headache disorders)-3 criteria
  • headache documented over at least 3 months through a headache calender
  • scheduled for prophylactic therapy of their migraine
  • not more than 3 years younger or older than matched control
  • gender similar to matched control
  • menstrual cycle equal to matched control (if female)

Who cannot join

  • history of chronic migraine
  • current medication-overuse headache
  • neurological or psychiatric diagnosis other than headaches
  • chronic intake of central nervous system active drugs (antidepressants, antipsychotics etc.)
  • contraindications for magnetic resonance imaging
  • contraindications for transcranial magnetic stimulation

About this study

Official title: Neurophysiological Characterization of Treatment Response Following the Initiation of Prophylactic Therapy in Episodic Migraine

This study aims to improve the pathophysiological understanding of migraine in in a longitudinal observational study investigating changes of established neurophysiological and imaging parameters in line with changes of the clinical phenotype.

The study's focus is the investigation of mechanisms that are directly related to the cyclic character of migraine and its core structures. In this context, the primary endpoint is a change in the nociceptive blink reflex, an established brain stem reflex to study the trigemino-spinal system, associated with changes in migraine frequency and severity. In order to reliably detect changes in the trigeminal pain system, investigations are performed in patients before starting a prophylactic therapy and 3 months afterwards. Several secondary endpoints are used to evaluate changes of multimodal sensory and cortical information processing. Cerebral imaging will include examinations of structural and network effects of altered migraine disease activity.

What participants receive

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

  • antibodies against calcitonin-gene related peptide or its receptorDrug

    the study is observational and does not interfere with clinical routine. In lin with this notion, the intervention is chosen by the treating physician in a shared decision making process involving the patient

What is being measured

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

  1. nociceptive blink reflex habituation

    habituation of the area under of the curve of the R2 blink reflex component on the side primarily affected by migraine headaches

    Measured: baseline and after 3 months

Secondary outcomes (7)
  1. nociceptive blink reflex area

    area under of the curve of the R2 blink reflex component on the side primarily affected by migraine headaches

    Measured: baseline and after 3 months

  2. somatosensory evoked potentials (SSEP)

    habituation of the N20 SSEP component following bilateral median nerve stimulation

    Measured: baseline and after 3 months

  3. pattern-reversal visual evoked potentials (VEP)

    habituation of the P100 VEP component following bilateral optic nerve stimulation

    Measured: baseline and after 3 months

  4. migraine headache frequency

    days with migraine headaches during the last month

    Measured: baseline and after 3 months

  5. headache impact test (HIT-6)

    impact of migraine severity on daily routine

    Measured: baseline and after 3 months

  6. migraine disability assessment (MIDAS)

    impact of migraine frequency on daily routine

    Measured: baseline and after 3 months

  7. Patient-Reported Outcomes Measurement Information System Profile 29 (PROMIS-29)

    multi domain patient reported quality of life

    Measured: baseline and after 3 months

Questions about this trial

What is this clinical trial studying?

An observational study of Migraine, run by University Medicine Greifswald at 1 site in Germany.

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 8 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 27 May 2021. 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 Germany. 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?

nociceptive blink reflex habituation (time frame: baseline and after 3 months). 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 NCT04019496, 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 27 May 2021.
