Exploring new treatments for migraine patients who don't respond to current therapies

Unraveling the Spectrum of Migraine Resistant to Treatments: Searching for Novel Biological PHEnotypes and theRApeutic Approaches (SPHERA Project)

IRCCS National Neurological Institute "C. Mondino" Foundation · NCT06562400

This study is testing new treatment options for migraine patients who haven't found relief with current therapies to see if they can help reduce their migraine days.

What this trial studies

This observational study aims to investigate novel therapeutic approaches for migraine patients who have not responded to monoclonal antibodies targeting the calcitonin gene-related peptide pathway. The focus is on understanding the dysfunction of the endocannabinoid system in these non-responders and evaluating the clinical, biochemical, and neurofunctional impacts of potential treatments like palmitoyl ethanolamide and a ketogenic diet. Patients will be identified based on their treatment history and the number of migraine days they experience. The study seeks to uncover new pathways for improving migraine management.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 to 75 with a diagnosis of chronic or episodic migraine who have not responded to at least three classes of migraine preventative treatments.

Not a fit: Patients with major psychiatric or neurological conditions, other primary headache disorders, or those who are pregnant or lactating may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective treatment options for patients suffering from chronic and episodic migraines who currently have limited relief.

How similar studies have performed: While the approach of targeting the endocannabinoid system in migraine treatment is relatively novel, previous studies have shown promise in normalizing dysfunctions within this system.

Eligibility criteria

* patients naive to CGRP targeting treatments

Exclusion Criteria:

* history of major psychiatric or other neurological conditions
* diagnosis of other primary or secondary headache disorders (only sporadic tension-type headache is allowed if the patients can clearly differentiate between the 2 types of headaches)
