New England Journal of Medicine Publishes Positive Phase 3 Data for Emgality® (galcanezumab-gnlm) in Episodic Cluster Headache
"Cluster headache is one of the most severe primary headache disorders, with excruciatingly painful recurrent headache attacks and remarkably limited treatment options," said
The study enrolled 106 patients who were randomized 1:1 to receive either 300 mg Emgality (via three 100 mg subcutaneous monthly injections) or placebo. Prior to enrollment, patients averaged 17.8 weekly cluster headache attacks in the Emgality arm (n=49) and 17.3 attacks in the placebo arm (n=57).1 Results showed that patients taking Emgality had an average reduction of 8.7 weekly cluster headache attacks across Weeks 1 to 3 compared to a 5.2 average reduction in attacks for placebo (p=0.036). Additionally, 71.4% of patients treated with Emgality had their weekly cluster headache attack frequency reduced by 50% or more at Week 3, the key secondary endpoint, compared to 52.6% of placebo-treated patients (p=0.046).1
"People with episodic cluster headache describe attacks as the most excruciating pain they have ever known. Despite the severity of this disease, there has been limited innovation to help treat cluster headache," said Gudarz Davar, M.D., vice president,
Overall, the safety profile observed in patients with episodic cluster headache treated with Emgality 300 mg monthly is consistent with the safety profile in patients with migraine treated with Emgality 120 mg monthly.1 Two Emgality-treated patients discontinued double-blind treatment during the episodic cluster headache study because of adverse events.1
Cluster headache is a disabling primary headache disorder.3 People with episodic cluster headache represent 85 to 90 percent of cluster headache prevalence, with approximately 250,000 adults living with this disease in the U.S.3,4 Cluster headache, although severely crippling, is challenging to diagnose because of limited awareness and, for some, may take five years or more to diagnose on average.5
Emgality is a monoclonal antibody that selectively binds to calcitonin gene-related peptide (CGRP) and was approved by the
Indications and Usage for Emgality (galcanezumab-gnlm) Injection
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.
Warnings and Precautions
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.

About the Phase 3 Study of Emgality in Cluster Headache
The Phase 3 study was a randomized, double-blind, placebo-controlled trial conducted at 35 sites in
In the study, 106 adult patients (18 to 65 years old) with episodic cluster headache, as determined by the ICHD-3-beta diagnostic criteria, were enrolled and randomly assigned to receive Emgality 300 mg (n=49) subcutaneously or placebo (n=57) subcutaneously once monthly for two months. Patients were allowed to use certain specified acute/abortive cluster headache treatments, including triptans, oxygen, acetaminophen, and NSAIDs during the study. The study's primary endpoint was the mean change from baseline in weekly cluster headache attack frequency across Weeks 1 to 3. The key secondary endpoint was the proportion of participants achieving a reduction from baseline of 50% or more in weekly cluster headache attack frequency at Week 3.1
About Cluster Headache
Cluster headache is a disabling primary headache disorder characterized by severe pain with recurrent 'attacks' of intense headaches which occur in cyclical patterns on one side of the head, frequently associated with pain behind or around one eye, restlessness and agitation.3 During a cluster period, attacks can last 15 to 180 minutes and occur from once every other day to eight times a day for more than half of the time during a cluster period.3 Episodic cluster headache is the most common form of the disease, affecting 85 to 90 percent of people with the disorder.3,4 In episodic cluster headache, attacks occur in series lasting for weeks or months (so-called cluster periods) separated by remission periods of at least three months.3

This press release contains forward-looking statements (as that term is defined in the Private Securities Litigation Reform Act of 1995) about Emgality (galcanezumab-gnlm) as a preventive treatment for patients with migraine and as a treatment for patients with episodic cluster headache and lasmiditan as a potential acute treatment for patients with migraine, and reflects Lilly's current belief. However, as with any pharmaceutical product, there are substantial risks and uncertainties in the process of development and commercialization. Among other things, there can be no guarantee that Emgality will receive additional regulatory approvals or be commercially successful. For further discussion of these and other risks and uncertainties, see Lilly's most recent Form 10-K and Form 10-Q filings with the
