Predicting response to anti-CGRP therapies

Salivary CGRP may predict response to anti-CGRP therapies, and patients with episodic migraine, less frequent migraine and a good response to triptans are more likely to be super-responders to CGRP mAbs.1.2 These were the conclusions from two studies investigating opportunities for precision medicine for migraine that were presented at the conference. In a further reported …
