DUBLIN, July 9, 2019 /PRNewswire/ -- Allergan plc (NYSE: AGN) announced today that the company will present 29 abstracts at the 61^st American Headache Society (AHS) Meeting, including one late-breaking podium presentation, five oral podium presentations and 23 poster presentations. The presentations will continue to highlight Allergan’s ongoing innovation in the treatment and understanding of migraine disease, bringing forth new data and insights across its expanding migraine franchise.

With an expected FDA decision in Q4 2019, Allergan continues to highlight data from its pivotal trials for ubrogepant, an investigational oral CGRP receptor antagonist for the acute treatment of migraine. Allergan will present a total of 14 ubrogepant focused abstracts, including ubrogepant in patients ineffectively treated with triptans, the effectiveness and safety of a second optional dose in achieving pain freedom at 2 hours, the safety of ubrogepant in patients with moderate to high cardiovascular risk, and the onset of pain relief.

BOTOX^® (onabotulinumtoxinA) remains a mainstay in the preventive treatment space and is a first-line treatment for Chronic Migraine. BOTOX^® will be featured in several presentations focused on safety, efficacy, and healthcare resource utilization with data evaluating impact on headache severity, headache-related impact, and quality of life in responder and nonresponder subgroups, and reductions in healthcare resource utilization. In addition, preclinical data from a mechanism of action study will be presented. This study evaluated a potential Chronic Migraine treatment approach that combines BOTOX^® and atogepant, the company’s second investigational, orally-administered CGRP receptor antagonist. Atogepant is currently in Phase III clinical trials for the prevention of migraine and will be highlighted in four abstracts at this year’s meeting.

“The strength of our data at AHS reinforces Allergan’s heritage and innovation in the migraine treatment space,” said David Nicholson, Chief Research and Development Officer, Allergan. “With a wealth of presentations highlighting BOTOX^®, ubrogepant and atogepant, Allergan is proud to showcase our ongoing commitment to the scientific advancement of our migraine franchise – Allergan MIND™ – and to the migraine community at large.” As part of Allergan’s ongoing commitment to innovating and inspiring change in the migraine community, the company has established a migraine franchise, Allergan MIND™ (Migraine: Innovation, Navigation, Discovery), to drive progress and unify its efforts as a worldwide leader in migraine.

Indication

BOTOX^® is a prescription medicine that is injected into muscles and used:

• To prevent headaches in adults with Chronic Migraine who have 15 or more days each month with headache lasting 4 or more hours each day in people 18 years or older

It is not known whether BOTOX^® is safe or effective to prevent headaches in patients with migraine who have 14 or fewer headache days each month (episodic migraine).

IMPORTANT SAFETY INFORMATION

BOTOX^® may cause serious side effects that can be life threatening. Get medical help right away if you have any of these problems any time (hours to weeks) after injection of BOTOX^®:

• Problems swallowing, speaking, or breathing, due to weakening of associated muscles, can be severe and result in loss of life. You are at highest risk if these problems are pre-existing before injection. Swallowing problems may last for several months.
• Spread of toxin effects. The effect of botulinum toxin may affect areas away from the injection site and cause serious symptoms including: loss of strength and all-over muscle weakness, double vision, blurred vision and drooping eyelids, hoarseness or change or loss of voice, trouble saying words clearly, loss of bladder control, trouble breathing, trouble swallowing.

There has not been a confirmed serious case of spread of toxin effect away from the injection site when BOTOX^® has been used at the recommended dose to treat chronic migraine.

BOTOX^® may cause loss of strength or general muscle weakness, vision problems, or dizziness within hours to weeks of taking BOTOX^®. If this happens, do not drive a car, operate machinery, or do other dangerous activities.

Do not receive BOTOX^® if you: are allergic to any of its ingredients (see Medication Guide for ingredients); had an allergic reaction to any other botulinum toxin product such as Myobloc^® (rimabotulinumtoxinB), Dysport^® (abobotulinumtoxinA), or Xeomin^® (incobotulinumtoxinA); have a skin infection at the planned injection site.

The dose of BOTOX^® is not the same as, or comparable to, another botulinum toxin product.

Serious and/or immediate allergic reactions have been reported, including itching, rash, red itchy welts, wheezing, asthma symptoms, or dizziness or feeling faint. Get medical help right away if you experience symptoms; further injection of BOTOX^® should be discontinued.

Tell your doctor about all your muscle or nerve conditions such as ALS or Lou Gehrig’s disease, myasthenia gravis, or Lambert-Eaton syndrome, as you may be at increased risk of serious side effects including difficulty swallowing and difficulty breathing from typical doses of BOTOX^®.

Tell your doctor about all your medical conditions, including if you: have or have had bleeding problems; have plans to have surgery; had surgery on your face; weakness of forehead muscles; trouble raising your eyebrows; drooping eyelids; any other abnormal facial change; are pregnant or plan to become pregnant (it is not known if BOTOX^® can harm your unborn baby); are breastfeeding or plan to (it is not known if BOTOX^® passes into breast milk).

Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Using BOTOX^® with certain medicines may cause serious side effects. Do not start any new medicines until you have told your doctor that you received BOTOX^® in the past.

Tell your doctor if you received any other botulinum toxin product in the last 4 months; have received injections of botulinum toxin such as Myobloc^®, Dysport^®, or Xeomin^® in the past (tell your doctor exactly which product you received); have recently received an antibiotic injection; take muscle relaxants; take allergy or cold medicines; take sleep medicine; take aspirin-like products or blood thinners.

Other side effects of BOTOX^® include: dry mouth, discomfort or pain at injection site, tiredness, headache, neck pain, eye problems: double vision, blurred vision, decreased eyesight, drooping eyelids, swelling of eyelids, and dry eyes; drooping eyebrows.

About Ubrogepant
Ubrogepant is an orally-administered CGRP receptor antagonist in development for the acute treatment of migraine. CGRP and its receptors are expressed in regions of the nervous system associated with migraine pathophysiology. CGRP receptor antagonism is a novel mechanism of action for the acute treatment of migraine that differs from the mechanisms of currently available triptans (serotonin 1B/1D agonists), opioids and ergots.

About Atogepant
Atogepant is an orally-administered CGRP receptor antagonist in development for the prevention of migraine. CGRP and its receptors are expressed in regions of the nervous system associated with migraine pathophysiology. It is chemically distinct from ubrogepant, our investigational orally-administered CGRP receptor antagonist for the acute treatment of migraine, and has demonstrated in preclinical studies to have a higher potency and longer half-life, making it potentially suitable for preventive treatment.

About Migraine Disease
Migraine is a chronic disease with episodic attacks defined by neurological symptoms such as headache pain, sensitivity to light and sound, and nausea; these symptoms are often incapacitating. Migraine is highly prevalent, affecting approximately 1 in 7 individuals, and is associated with significant disability leading to high personal, family, societal, and economic burden. Despite its prevalence and the availability of treatments, migraine is an underdiagnosed and undertreated disease. There is a need for new treatments for migraine with improved benefit-risk profiles to fulfill this unmet need.

Allergan, a leader in the migraine space, markets BOTOX® (onabotulinumtoxinA) the first FDA-approved, preventive treatment for adult Chronic Migraine patients since it was approved in 2010. Allergan is also advancing its migraine program with two investigational small molecule oral calcitonin gene-related peptide (CGRP) receptor antagonists, which are being developed for the acute treatment and prevention of migraine. The U.S. FDA has accepted the company’s New Drug Application (NDA) for ubrogepant for the acute treatment of migraine in adults, and a PDUFA date is expected in the fourth quarter of 2019. Ubrogepant is expected to be the first oral CGRP receptor antagonist to market. In addition, atogepant is currently in Phase 3 development for the prevention of migraine.
