Investigating the effects of anti-CGRP medications on bone health in migraine patients

Potential Osteocatabolic Effect Caused by Anti-CGRP MAbs in Migraine Patients Treated with Anti-CGRP MAbs - an Observational Pilot Project with Prospectively Collected Health Related Data

Observational Ente Ospedaliero Cantonale, Bellinzona · NCT06035458

This study is testing whether anti-CGRP medications used for migraines affect bone health in people who take them compared to those who don’t.

What this trial studies

This observational pilot project aims to explore the potential osteocatabolic effects of anti-CGRP monoclonal antibodies (mAbs) in patients suffering from migraines. The study will collect health-related data over a period of 6, 12, and 24 months to assess changes in bone density, structure, and metabolic turnover among participants. It will include both a treatment group receiving anti-CGRP mAbs and a control group not receiving these medications, allowing for a comparative analysis of outcomes. The research is significant as it addresses a previously unexplored area regarding the long-term effects of migraine treatments on bone health.

Who should consider this trial

Good fit: Ideal candidates include males and females aged 18 to 50 who are planning to start treatment with anti-CGRP mAbs and have a history of ineffective prior migraine preventive therapies.

Not a fit: Patients who are not planning to start anti-CGRP mAbs or those who have never been treated with these medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management strategies for migraine patients, particularly concerning their bone health.

How similar studies have performed: While this specific investigation is novel, other studies have shown the efficacy of anti-CGRP mAbs in treating migraines, but their effects on bone health remain largely untested.
