AGX-201 is a histamine receptor modulator that acts as an antagonist at H1 receptors and an agonist at H3 receptors. This dual mechanism of action offer a unique approach to mitigate migraine symptoms by reducing the release of proinflammatory neuropeptides from trigeminal nerve endings. Subcutaneous AGX-201 is currently tested in a phase II trial (NCT02021474) enrolling subjects with migraine requiring prophylactic treatment.
