- Patients with episodic migraine taking investigational treatment erenumab over six months reported reduced migraine days and acute medication use1
- Fifty per cent of patients taking erenumab 140mg had their migraine days cut by at least half1
- Patients on erenumab reported reduced physical impairment and improved ability to participate in daily activities based on a validated patient-reported outcome tool1
DORVAL, QC, Nov. 30, 2017 /CNW/ - Novartis has announced that The New England Journal of Medicine (NEJM) has published results from the six-month Phase III STRIVE study evaluating the investigational treatment erenumab in the prevention of episodic migraine (defined in the study as 4 to 14 migraine days per month)1. Erenumab is specifically designed to block the calcitonin gene-related peptide (CGRP) receptor, which is known to play an important role in migraine activation1. Erenumab is an investigational treatment that is not currently approved for use in Canada or elsewhere.
"We are pleased to have been able to evaluate this new approach to migraine prevention. Migraine can be a crippling condition for the more than eight per cent of Canadians who suffer from it2," said Dawn Bell, Chief Scientific Officer, Novartis Pharmaceuticals Canada Inc. "The results from this study are important clinical evidence for this investigational therapy and we are pleased to be conducting research in this area."
The STRIVE study enrolled 955 patients, who were randomized to receive either placebo or subcutaneous (injection administered under the skin) erenumab 70mg or 140mg once a month, for six months. Five centers in Canada participated in the study3. Overall, erenumab treatment resulted in statistically significant differences from placebo for all primary and secondary endpoints1 including number of migraine days, acute medication use, as well as reduced physical impairment and greater ability to participate in daily activities, as measured by the novel, validated Migraine Physical Function Impact Diary (MPFID)4.
"The STRIVE study is the first fully completed phase III study of a preventive migraine medication acting on the CGRP pathway. These results represent a step forward for migraine understanding and preventive migraine treatment development," said Dr. Suzanne Christie, neurologist and Director at The Ottawa Headache Centre in Ottawa, Ontario and one of the STRIVE study investigators. "Migraine is more than a headache. For migraine sufferers it is a very serious condition that can substantially impact all aspects of person's daily life. As a treating physician, migraine prevention is a high priority."
STRIVE (NCT02456740) is a global Phase III, multicentre, randomized 24-week, double-blind, placebo-controlled study evaluating the safety and efficacy of erenumab in episodic migraine (4 to 14 migraine days a month) prevention. In the study, 955 patients were randomized to receive once-monthly subcutaneous placebo, or erenumab (70mg or 140mg) 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.
In STRIVE, patients taking erenumab at the higher 140mg dose experienced a significant 3.7-day reduction in monthly migraine days from the baseline of 8.3 days (3.2-day reduction with 70mg, 1.8-day reduction with placebo, both p<0.001). Fifty percent of patients taking erenumab 140mg had their migraine days cut by at least half (43.3% with 70mg; 26.6% with placebo, both p<0.001; odds ratios of 2.8 and 2.1 respectively for 140mg and 70mg). STRIVE endpoints were assessed from baseline to the average of the last three months (months 4, 5, 6)1.
In STRIVE, more than 90 per cent of patients taking erenumab completed the study. Adverse reactions leading to discontinuation of treatment occurred in 2.2 per cent of erenumab-treated patients and in 2.5 per cent of patients receiving placebo1. STRIVE contributes to the body of evidence on erenumab, including four placebo-controlled Phase II and Phase III clinical studies involving more than 2,600 patients, as well as an ongoing open-label extension up to five years in duration.
Migraine is a chronic biological disorder that causes recurrent attacks of head pain that is often associated with nausea and vomiting and can involve sensitivity to light and sound5.
Migraine causes significant disability, seven million workdays are reportedly lost to it annually, which is likely under-reported. Most sufferers develop their first migraine headache in adolescence or early adulthood6. The highest prevalence rates in Canada are among people in their 30s and 40s and women are more than twice as likely as men to report having migraine. People with migraine are much more likely to suffer from depression. It is a disease that impacts many areas of daily living, including education, work, sleep, and driving2.
About Amgen and Novartis Neuroscience Collaboration
In August 2015, Amgen entered into a global collaboration with Novartis to jointly develop and commercialize pioneering treatments in the field of migraine and Alzheimer's disease (AD). The collaboration focuses on investigational Amgen drugs in the migraine field, including erenumab (Biologics License Application submitted to U.S. FDA in May 2017) and AMG 301 (currently in Phase 1 development). In April 2017, the collaboration was expanded to include co-commercialization of erenumab in the U.S. For the migraine program, Amgen retains exclusive rights in Japan, and Novartis has exclusive 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 AD. The oral therapy CNP520 (currently in Phase 3 for AD) is the lead molecule and further compounds from both companies' pre-clinical BACE inhibitor programs may be considered as follow-on molecules.
