Amgen To Highlight Extensive Long-Term Safety And Efficacy Data Of Aimovig® (erenumab-aooe) Across The Spectrum Of Migraine At AAN Annual Meeting
Migraine is a highly debilitating disease that has a profound and limiting impact on peoples' lives, including time spent with family and friends, or at work.2,3 Aimovig, co-commercialized in the U.S. by

Data in Chronic Migraine
An exploratory analysis of one-year OLE data from the pivotal study evaluating the efficacy and safety of Aimovig in chronic migraine prevention assessed the conversion rate from chronic to episodic migraine.4 The results at 52 weeks showed more than two-thirds of patients with chronic migraine on Aimovig converted to episodic migraine by the last dose received. Patients converting to episodic migraine showed a reduction of 11 monthly migraine days (MMD) at week 52, from a baseline of 17 MMD. Both doses had high conversion rates, with the Aimovig 140 mg dose numerically higher (76 percent) compared to Aimovig 70 mg (69 percent).
"Millions of people with chronic migraine spend at least half of each month living with the debilitating symptoms of this disease," said
Further data from the study evaluating the long-term efficacy and safety results of Aimovig in patients with chronic migraine during open-label treatment are being presented at AAN.
Data in Episodic Migraine
One-year results of the Phase 3 STRIVE study (including 24-week double-blind phase and 28-week active treatment phase [ATP]) showed Aimovig provided sustained efficacy in the prevention of episodic migraine and a safety profile comparable to that observed in prior studies.5
At week 52, patients receiving Aimovig 70 mg or 140 mg from week 24 onward had an average of 4.2 and 4.6 fewer MMD, respectively, compared to study baseline (8.3 MMD). They also continued to experience improvements during the ATP (1.1 and 1.8 fewer MMD, respectively). In addition, an analysis of responder rates from baseline showed more than six out of 10 patients on either dose of Aimovig had 50 percent fewer MMD; around four out of 10 had 75 percent fewer MMD; and one in five were migraine-free at week 52.
Additional data from STRIVE and the OLE phase of the LIBERTY study in patients taking Aimovig with episodic migraine who had failed prior preventive treatments are being presented at AAN.
About the Open-Label Extension Study in Chronic Migraine
The OLE of the pivotal parent study (NCT02066415) was a 52-week, multicenter study (OLE, NCT02174861) evaluating the long-term efficacy and safety of Aimovig in chronic migraine prevention in patients taking Aimovig 70 mg and 140 mg. Patients initially enrolled received 70 mg of Aimovig monthly. The protocol was amended for patients to receive 140 mg of Aimovig. Patients who had completed the week-28 visit at the time of the amendment continued to receive Aimovig 70 mg, and patients who had enrolled but had not completed the week-28 visit at the time of the amendment increased from 70 mg to 140 mg of Aimovig at the next visit such that these patients would have the opportunity to receive at least six months of Aimovig 140 mg during the 52-week study. All patients who enrolled after the amendment received Aimovig 140 mg throughout the study.
Proportions of episodic migraine converters/nonconverters based on observed data were summarized throughout the OLE (overall population) and by last dose received (70 mg or 140 mg). Efficacy data were collected at weeks 1–12, 21–24, 37–40, and 49–52; endpoints included change from parent study baseline in monthly migraine days (MMD) and proportion of patients with ≥50 percent reduction from parent study baseline in MMD.
STRIVE (Study to Evaluate the Efficacy and Safety of Erenumab in Migraine Prevention, NCT02456740) is a global Phase 3, multicenter, randomized 24-week, double-blind, placebo-controlled study evaluating the safety and efficacy of Aimovig in episodic migraine (characterized in this study as ≥4 to <15 migraine days per month and <15 headache days per month on average across the three months before screening) prevention. In the study, 955 patients were randomized to receive once-monthly subcutaneous placebo, or Aimovig (70 mg or 140 mg) in a 1:1:1 ratio. Patients experienced between four and 14 migraine days each month, with an average of 8.3 migraine days per month at baseline. The primary endpoint was change in mean monthly migraine days from baseline over the last three months of the double-blind treatment phase of the study (months 4, 5 and 6). Secondary study endpoints assessed included reduction of at least 50 percent from baseline in mean MMD, change from baseline in mean monthly acute migraine-specific medication days, and changes from baseline in both mean impact on everyday activities domain and mean physical impairment domain scores on the Migraine Physical Function Impact Diary (MPFID).
At week-24 (ATP baseline), 845 patients were re-randomized (1:1) to Aimovig 70 mg or 140 mg for the subsequent 28-week dose-blinded ATP. Assessments included MMD; monthly acute migraine-specific medication days (MSMD); proportion of patients achieving a ≥50 percent, ≥75 percent, and 100 percent reduction in MMD (responder rates: RR); and safety.
About Aimovig® (erenumab-aooe)
Aimovig is the only
Aimovig® (erenumab-aooe) is indicated for the preventive treatment of migraine in adults.
IMPORTANT SAFETY INFORMATION
Contraindication: Aimovig® is contraindicated in patients with serious hypersensitivity to erenumab-aooe or to any of the excipients. Reactions have included anaphylaxis and angioedema.
Hypersensitivity Reactions: Hypersensitivity reactions, including rash, angioedema, and anaphylaxis, have been reported with Aimovig® in post marketing experience. Most reactions were not serious and occurred within hours of administration, although some occurred more than one week after administration. If a serious or severe reaction occurs, discontinue Aimovig® and initiate appropriate therapy.
Adverse Reactions: The most common adverse reactions in clinical studies (≥ 3% of Aimovig®-treated patients and more often than placebo) were injection site reactions and constipation.

People with frequent migraine may lose more than half their life to migraine. They endure debilitating pain, physical impairment, and live in constant dread of the next attack – all of which is compounded by a widespread misperception of the disease.3 The 2017 Global Burden of Disease Study ranks migraine among the top 10 causes of years lived with disability worldwide.6 Migraine is associated with personal and societal burdens of pain, disability, and financial cost, and it remains under-recognized and under-treated.3
In August 2015, Amgen entered into a global collaboration with Novartis to develop and commercialize pioneering treatments in the field of migraine and Alzheimer's disease. The collaboration focuses on investigational Amgen drugs in the migraine field, including Aimovig (approved by the FDA in May 2018 for the preventive treatment of migraine in adults). In April 2017, the collaboration was expanded to include co-commercialization of Aimovig in the U.S. For the migraine programs, Amgen retains exclusive commercialization rights in the U.S. (other than for Aimovig as described above) and Japan, and Novartis has exclusive commercialization rights in Europe, Canada and rest of world. Also, the companies are collaborating in the development and commercialization of a beta-secretase 1 (BACE) inhibitor program in Alzheimer's disease. The oral therapy CNP520 (currently in Phase 3 for Alzheimer's disease) is the lead molecule and further compounds from both companies' pre-clinical BACE inhibitor programs may be considered as follow-on molecules. At the center of the Amgen and Novartis neuroscience collaboration is the shared mission to fight migraine and the stereotypes and misperceptions surrounding this debilitating disease.
