Study Endpoints

Primary Endpoints

Change From Baseline in Monthly Migraine Days During the Last 4 Weeks of the 12-week Treatment Period
baseline (4 weeks period prior to start of study drug), week 9 to 12

A migraine day was defined as any calendar day in which the subject experienced a qualified migraine headache (onset, continuation, or recurrence of the migraine headache). A qualified migraine headache was defined as a migraine with or without aura, lasting for ≥4 continuous hours, and meeting at least one of the following criteria: 1. ≥2 of the following pain features: * Unilateral * Throbbing * Moderate to severe * Exacerbated with exercise/physical activity 2. ≥1 of the following associated symptoms: * Nausea and/or vomiting * Photophobia and phonophobia

Change From Baseline in Monthly Migraine Days at the Last Month (Month 3) of the Double-blind Treatment Period (DBTP)
Baseline up to Month 3

A migraine day was defined as any calendar day in which the subject experienced a qualified migraine headache defined as a migraine with or without aura, lasting for ≥ 30 minutes, and meeting at least one of the following criteria: 1. ≥ 2 of the following pain features: unilateral, throbbing, moderate to severe or exacerbated with exercise/physical activity 2. ≥ 1 of the following associated symptoms: nausea and/or vomiting, photophobia and phonophobia

Frequently asked questions about Erenumab

What is erenumab used for?

Erenumab is used for the preventive treatment of migraine, including episodic migraine and chronic migraine, in adults. It is a monoclonal antibody developed for the neurology therapeutic area and has been studied in Phase 3 clinical trials in adult patients with these headache disorders.

What does erenumab target?

Erenumab targets CALCRL, acting as an antagonist at this receptor. By blocking this target, erenumab is designed to interfere with the signaling pathway involved in migraine. This mechanism underlies its development as a preventive therapy for episodic and chronic migraine in adults.

Who makes erenumab?

Erenumab is developed by Novartis AG, which trades under the ticker NVS. Novartis has sponsored the Phase 3 clinical development program for erenumab in adult migraine patients, including trials conducted across multiple countries in Asia, Latin America, and the Middle East.

What phase is erenumab in?

Erenumab is in Phase 3 clinical development. Its Phase 3 trials in adult episodic migraine and chronic migraine have been completed. The program includes randomized, double-blind, placebo-controlled studies, and the drug remains an investigational therapy in clinical development for migraine prevention.

What clinical trials is erenumab in?

Erenumab has been studied in Phase 3 trials including NCT03333109, which evaluated AMG 334 in adult episodic migraine patients with 900 participants, and NCT03867201, which studied erenumab in adult chronic migraine patients with 557 participants. Both trials are completed and enrolled adults aged 18 years and older.

Is erenumab the same as AMG 334?

Yes, erenumab is also known as AMG 334. The Phase 3 episodic migraine trial NCT03333109 is titled as a study of AMG 334, which is the same monoclonal antibody as erenumab. Both names refer to the same investigational therapy developed by Novartis for migraine prevention.
