FDA Approves Broadened Indication for XEOMIN® (incobotulinumtoxinA) as First-Line Treatment for Blepharospasm (Involuntary Blinking) in Adult Patients

Merz Americas announced today that the U.S. Food and Drug Administration (FDA) has approved the supplemental Biologics License Application (sBLA) for XEOMIN®(incobotulinumtoxinA), broadening its indication to be a first-line treatment of blepharospasm (involuntary blinking) in adult patients.

“Merz is proud to offer a first-line treatment option for blepharospasm, a devastating condition that has no cure and affects up to 50,000 patients in the U.S.,”1 said Kevin O’Brien, Vice President and U.S. Head of Neurosciences, Merz. “This milestone, along with the July 2018 approval of XEOMIN for the treatment of chronic sialorrhea (drooling) in adults, reinforces our commitment to providing comprehensive care for patients living with movement disorders.”

Blepharospasm causes muscles around the eyes to contract involuntarily. Patients suffering from blepharospasm can experience symptoms including excessive blinking, light sensitivity, dry eyes, eye irritation and watering eyes, and symptoms may worsen over time.1,2

The approval is based on a Phase 3, randomized, double-blind, placebo-controlled, multi-center trial in a total of 61 treatment-naïve patients who had a diagnosis of blepharospasm with a baseline Jankovic Rating Scale (JRS) Severity subscore ≥2.  JRS is the most commonly used clinical scale to measure severity and frequency of blepharospasm.Patients were defined as treatment-naïve if at least 12 months had passed since their last toxin treatment.

The primary efficacy endpoint was the change from baseline in JRS Severity subscore determined at week 6 after the XEOMIN injection. The 50 unit treatment group demonstrated statistically significant improvement compared to placebo, with a difference of -1.2 (p=0.0004). The safety findings were similar to previous studies and in line with the known safety profile of XEOMIN.

XEOMIN was first approved by the FDA in 2010 for the treatment of blepharospasm (previously treated with onabotulinumtoxinA) and cervical dystonia in adult patients and later in 2015 for upper limb spasticity in adult patients. Most recently, XEOMIN was approved by the FDA in July 2018 to treat chronic sialorrhea (excessive drooling) in adult patients.

Warnings

XEOMIN may cause serious side effects that can be life threatening.  Call your doctor or get medical help right away if you have any of these problems anytime (hours to weeks) after treatment with XEOMIN:

  • Problems with swallowing, speaking, or breathing can happen within hours to weeks after an injection of XEOMIN if the muscles that you use to breathe and swallow become weak. Death can happen as a complication if you have severe problems with swallowing or breathing after treatment with XEOMIN.
    • People with certain breathing problems may need to use muscles in their neck to help them breathe and may be at greater risk for serious breathing problems with XEOMIN.
    • Swallowing problems may last for several months, and during that time you may need a feeding tube to receive food and water. If swallowing problems are severe, food or liquids may go into your lungs. People who already have swallowing or breathing problems before receiving XEOMIN have the highest risk of getting these problems.
  • Spread of toxin effects.In some cases, the effect of botulinum toxin may affect areas of the body away from the injection site and cause symptoms of a serious condition called botulism. The symptoms of botulism include: loss of strength and muscle weakness all over the body, 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.

These symptoms can happen hours to weeks after you receive an injection of XEOMIN. These problems could make it unsafe for you to drive a car or do other dangerous activities.

Do not take XEOMIN if you: are allergic to XEOMIN or any of the ingredients in XEOMIN (see the end of this Guide for a list of ingredients in XEOMIN), had an allergic reaction to any other botulinum toxin product such as rimabotulinumtoxinB (MYBLOC®), onabotulinumtoxinA (BOTOX®, BOTOX® COSMETIC), or abobotulinumtoxinA (DYSPORT®) or have a skin infection at the planned injection site.

Especially tell your doctor if you:

  • have received any other botulinum toxin product in the last four months
  • have received injections of botulinum toxin such as rimabotulinumtoxinB (MYOBLOC®), onabotulinumtoxinA (BOTOX®, BOTOX®COSMETIC) and abobotulinumtoxinA (DYSPORT®) in the past.
