FDA Approves BOTOX(R) (onabotulinumtoxinA) for Pediatric Patients with Upper Limb Spasticity

BOTOX® is the First Neurotoxin Treatment Approved to Treat Pediatric Patients, 2 to 17 Years of Age, with Upper Limb Spasticity

Approval Marks 10th BOTOX® Therapeutic Indication in its 30th Anniversary Year


DUBLIN, June 21, 2019 -- (Healthcare Sales & Marketing Network) -- Allergan plc (NYSE: AGN) today announced that the U.S. Food and Drug Administration (FDA) approved the company's supplemental biologics application (sBLA) for BOTOX® for the treatment of pediatric patients (2 to 17 years of age) with upper limb spasticity. BOTOX® was granted a six-month Priority Review by the FDA, which is typically granted to therapies that if approved, could offer significant improvements in safety and effectiveness when compared to current standard of care. The FDA is also reviewing an additional sBLA for the use of BOTOX® to treat pediatric patients with lower limb spasticity, with a decision expected in the fourth quarter of this year.

Damage to the brain and spine can result in spasticity, which is often observed as muscle tightness and stiffness in the upper and lower limbs. Upper limb spasticity can interfere with movement at the joints of the upper limb and its severity can range from mild to severe muscle stiffness. Common causes of spasticity in children include cerebral palsy, traumatic brain injury, multiple sclerosis, spinal cord injury, and stroke, which is a group of disorders affecting one's ability to move and maintain balance and posture.

"Watching a child suffering with any degree of upper limb spasticity is very difficult," said David Nicholson, Chief Research and Development Officer, Allergan. "This FDA approval is special to all of us at Allergan because we can now provide children and their caregivers an advancement in pediatric care with BOTOX®. This milestone underscores our constant focus on innovation and builds on our 30-years of research and development efforts with BOTOX® since FDA approval of blepharospasm and strabismus in 1989. We also look forward to the FDA's decision on pediatric lower limb spasticity and continuing to serve our patients globally."

The FDA approval is based on data from two Phase 3 studies evaluating the safety and efficacy of BOTOX® in over 200 pediatric patients with upper limb spasticity. These trials included a 12-week, double-blind study and a one-year open-label extension study.

The approved recommended dose per treatment session is 3 Units per kilogram to 6 Units per kilogram divided among affected muscles of the upper limb. The total dose in pediatric patients should not exceed 8 Units per kilogram body weight or 300 Units, whichever is lower, in a 3-month interval. Treatment with BOTOX® is not meant to replace existing physical therapy or other rehabilitation that may have been prescribed.

"Pediatric upper limb spasticity is a significant concern and can negatively impact a child's development and quality of life," said Mark Gormley, Jr. M.D., Pediatric Rehabilitation Medicine Specialist, Gillette Children's Specialty Healthcare-St. Paul. "Because spasticity is particularly debilitating to growing children, it requires ongoing care. BOTOX® has a well-established safety and efficacy profile and I believe it will be an important treatment option in helping successfully manage upper limb spasticity in children and adolescents."

Allergan is committed to providing resources and services, such as the BOTOX® Savings Program, to help ensure BOTOX® is accessible and affordable to patients. Over the past 30 years, more than 100 million vials of BOTOX® and BOTOX® Cosmetic (onabotulinumtoxinA) have been distributed worldwide. With more than 3,700 articles on BOTOX® and BOTOX® Cosmetic published in scientific and medical journals, BOTOX® neurotoxin is one of the most widely researched medicines in the world.

BOTOX® (onabotulinumtoxinA) Important Information

Indications

BOTOX® is a prescription medicine that is injected into muscles and used:
  • to treat increased muscle stiffness in children 2 to 17 years of age with upper limb spasticity
  • to treat certain types of eye muscle problems (strabismus) or abnormal spasm of the eyelids (blepharospasm) in people 12 years and older
Treatment with BOTOX® in children 2 to 17 years of age with upper limb spasticity is not meant to replace existing physical therapy or other rehabilitation that may have been prescribed.

It is not known whether BOTOX® is safe or effective for other types of muscle spasms.

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 the 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, and 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 blepharospasm or strabismus.

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 the ingredients in BOTOX® (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®.

Cornea problems have been reported. Cornea (surface of the eye) problems have been reported in some people receiving BOTOX® for their blepharospasm, especially in people with certain nerve disorders. BOTOX® may cause the eyelids to blink less, which could lead to the surface of the eye being exposed to air more than is usual. Tell your doctor if you experience any problems with your eyes while receiving BOTOX®. Your doctor may treat your eyes with drops, ointments, contact lenses, or with an eye patch.

Bleeding behind the eye has been reported. Bleeding behind the eyeball has been reported in some people receiving BOTOX® for their strabismus. Tell your doctor if you notice any new visual problems while receiving BOTOX®.

Bronchitis and upper respiratory tract infections (common colds) have been reported. In pediatric patients treated with BOTOX® for upper limb spasticity, upper respiratory tract infections were reported more frequently.

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 other medicines may cause serious side effects. Do not start any new medicines until you have told your doctor that you have 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 by injection; take muscle relaxants; take an allergy or cold medicine; take a sleep medicine; take aspirin-like products or blood thinners.

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

For more information refer to the Medication Guide or talk with your doctor. You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch or call 1-800-FDA-1088.
