CGRP is thought to play a central role in migraine pathogenesis6

Elevated levels of calcitonin gene-related peptide (CGRP) can lead to a cascade of vasodilation and pain associated with migraine attacks, as observed in preclinical studies of CGRP6

  • CGRP, released from the trigeminal ganglia, is elevated during migraine6
  • An infusion of CGRP can induce migraine attacks in susceptible individuals, and CGRP is involved in the transmission of pain7,8
  • Perivascular release of CGRP has been shown to induce vasodilation and plasma protein leakage from tissues6

Indications and Important Safety Information

Emgality is a calcitonin gene-related peptide (CGRP) antagonist indicated in adults for the:

  • Preventive treatment of migraine
  • Treatment of episodic cluster headache

Important Safety Information

Emgality is contraindicated in patients with serious hypersensitivity to galcanezumab-gnlm or to any of the excipients.

Hypersensitivity Reactions
Hypersensitivity reactions, including anaphylaxis, angioedema, dyspnea, urticaria, and rash, have been reported with Emgality. If a serious or severe hypersensitivity reaction occurs, discontinue administration of Emgality and initiate appropriate therapy. Hypersensitivity reactions can occur days after administration and may be prolonged.

The most common adverse reactions (incidence ≥2% and at least 2% greater than placebo) in Emgality clinical studies were injection site reactions.

Please see Full Prescribing Information, including Patient Information, for Emgality. See Instructions for Use included with the device.
