Insights

FDA approval of Brekiya gives Amneal a unique position in the large migraine market with potential for significant revenue impact.

The FDA approval of Brekiya represents a significant milestone for Amneal Pharmaceuticals and a potentially valuable addition to their specialty portfolio. This first-in-class DHE autoinjector addresses several unmet needs in the substantial migraine market affecting 39 million Americans and cluster headache market affecting up to 1 million Americans.

The product's unique positioning is its key advantage. As the first and only DHE autoinjector, Brekiya allows patients to self-administer the same medication used in hospitals without visiting emergency rooms. The market opportunity is substantial since headaches account for 3% of all ER visits in the US, representing the fourth most common reason for emergency department visits.

From a competitive standpoint, Brekiya offers several differentiating features: it doesn't require refrigeration, assembly, or priming, making it user-friendly. It's particularly valuable for patients who respond inadequately to oral therapies, experience nausea/vomiting during attacks, have gastroparesis, or delay dosing.

Importantly, this approval addresses the underserved cluster headache population where treatment options have been limited. The scheduled commercial availability in the second half of 2025 gives Amneal time to prepare their market launch strategy.

Amneal has historically focused on generics, so this specialty product represents continued execution of their strategy to expand into higher-margin branded products. This approval should help diversify their revenue streams while potentially improving their overall margin profile.

  • Brekiya® becomes the first and only DHE autoinjector that allows patients to self-administer the same medication used in hospitals in a ready-to-use form
  • Product will be available for appropriate patients in the second half of 2025

BRIDGEWATER, N.J., May 15, 2025 (GLOBE NEWSWIRE) -- Amneal Pharmaceuticals, Inc. (Nasdaq: AMRX) (“Amneal” or the “Company”) today announced that the U.S. Food and Drug Administration (FDA) has approved Brekiya® (dihydroergotamine mesylate) injection, the first and only dihydroergotamine (DHE) autoinjector for the acute treatment of migraine with or without aura and the acute treatment of cluster headaches in adults.1,2

Brekiya autoinjector provides patients with the potential for sustained* pain relief in a convenient, self-administered form.1,3,4 It contains the same medication (DHE) used in hospitals, now in a ready-to-use device.1,5 Brekiya autoinjector does not require refrigeration, assembly, or priming of the device.1 Patients can deliver one dose subcutaneously into the middle of the thigh.1 This may be beneficial for patients who respond inadequately to oral therapies due to lack of efficacy, experience nausea or vomiting during attacks, have gastroparesis, or delay dosing until too late into the attack.1,5,6
        
“We are thrilled to offer the first and only ready-to-use autoinjector for patients suffering from acute migraine and cluster headaches. Physicians are familiar with DHE, which is an effective and well-established therapy that provides sustained relief for headaches. Our single-dose autoinjector represents an innovative therapeutic option for patients that allows for quick self-administration of the medication during these painful attacks without visiting the emergency room,” said Joe Renda, Senior Vice President, Chief Commercial Officer – Specialty.

DHE is commonly administered in emergency rooms, urgent care facilities, and headache clinics intravenously. DHE can be used at any point during a migraine attack, and may protect patients from headache recurrence.1,3,4 Approximately 39 million Americans are living with migraine7, and up to one million with cluster headache.8 Also, headache is the fourth most common reason for emergency department visits, and accounts for 3% of all emergency room visits in the United States.9 There are limited treatment options available for cluster headache, and Brekiya autoinjector represents a new treatment option for this underserved population.2
