What This Study Found

Three CGRP-targeting monoclonal antibodies are FDA-approved for migraine prevention, reducing attack frequency through a targeted mechanism not available with older drugs.

Key Numbers

39M Americans; 1 in 7 ages 15-49; 3x more in women; 3 FDA-approved mAbs

How They Did This

Review of clinical trial data and FDA-approved indications for erenumab, fremanezumab, and galcanezumab.

Why This Research Matters

Migraine affects 1 in 7 people ages 15-49 and is 3 times more common in women. These first-in-class targeted preventive medications fill a critical gap for patients who couldn't tolerate existing treatments.

The Bigger Picture

CGRP antibodies represent a paradigm shift — the first medications designed specifically for migraine prevention based on understanding of migraine neurobiology.

What This Study Doesn't Tell Us

Brief review without detailed comparative efficacy data. Long-term safety beyond trial durations is still being monitored.

Questions This Raises

  • ?How do the three CGRP antibodies compare in efficacy and side effects?
  • ?What is the optimal duration of treatment?
  • ?Can CGRP antibodies be combined with other preventives?

Frequently Asked Questions

How do CGRP antibodies prevent migraines?

These antibodies block CGRP, a neuropeptide central to migraine. Erenumab blocks the CGRP receptor, while fremanezumab and galcanezumab bind CGRP itself, preventing it from activating the receptor.

Who should consider CGRP antibodies?

They are indicated for adults with episodic or chronic migraine, particularly those who haven't responded to or couldn't tolerate existing preventive medications.
