Data from Merz Aesthetics’ Post-Market Clinical Study of Xeomin® (incobotulinumtoxinA) vs. Botox® (onabotulinumtoxinA) for Glabellar Facial Lines Published in Dermatologic Surgery

, a division of Merz North America (U.S. affiliate of the
global Merz Pharma Group), today announced that the medical journal “Dermatologic
“ (Wolters Kluwer) has published data from its post-market,
prospective parallel group clinical trial evaluating the efficacy of Xeomin®
in the treatment of moderate to severe glabellar facial lines, when
compared to Botox® Cosmetic (onabotulinumtoxinA). The article
titled “A
Randomized, Double-Blind Trial to Investigate the Equivalence of
IncobotulinumtoxinA and OnabotulinumtoxinA for Glabellar Frown Lines“

is now available in the November 2015 issue of the journal.

Dermatologic Surgery’s publication of this new clinical data
demonstrating the efficacy of Xeomin® (incobotulinumtoxinA)
will prove critical in encouraging physicians to consider Xeomin®
(incobotulinumtoxinA) for their patients as an effective treatment for
glabellar lines,“ said Jim Hartman, Vice President and U.S. Head – Merz
Aesthetics Injectables. “Merz remains committed to delivering a better
total experience in aesthetics, and we are proud to offer patients and
physicians a full palette of treatment options across the aesthetic
device, injectables and skincare categories.”

Clinical trial results show that this parallel group study met its
primary efficacy endpoint of clinical equivalence, defined as ≥ 1-point
improvement from baseline on the Facial Wrinkle Scale (FWS) at maximum
frown, 1 month after a single treatment. Similar efficacy and
tolerability profiles were demonstrated between the two treatment groups
at all timepoints (1, 2, 3 and 4 months post-treatment). The most common
adverse events seen in both treatment groups were headache, infection
and facial asymmetry.

“As the first large, randomized, multicenter direct comparator study to
date using the FDA recommended dose of 20 units, this trial represents
the definitive U.S. comparison study of Xeomin®
(incobotulinumtoxinA) versus Botox® (onabotulinumtoxinA) for
the treatment of glabellar facial lines. These study results further
confirm the literature demonstrating similar efficacy and safety
profiles for both products,“ stated Dr.
Michael Kane, MD
, co-principal investigator of the study. A
board-certified plastic surgeon in private practice in Manhattan, NY,
Dr. Kane frequently lectures on topics relating to aesthetic plastic
surgery and has published hundreds of papers throughout his career.

Botulinum toxin type A is a well-established treatment for glabellar
frown lines. In 2011, Xeomin® (incobotulinumtoxinA) was
approved by the FDA for improvement in the appearance of
moderate-to-severe glabellar frown lines with a recommended dosage of 20
units (U). Head-to-head comparison studies conducted worldwide have
demonstrated that treatment with Xeomin®
(incobotulinumtoxinA) and Botox® (onabotulinumtoxinA) result
in comparable safety and efficacy for both cosmetic use and therapeutic
uses, including blepharospasm and cervical dystonia.1

between the eyebrows (glabellar lines) in adults for a short period of
time (temporary).


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 week) after
treatment with XEOMIN

  • Problems with swallowing, speaking, or breathing. These
    problems can happen hours to weeks after an injection of XEOMIN
    if the muscles that you use to breathe and swallow become weak after
    the injection. 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. These patients may be at greater risk
    for serious breathing problems with XEOMIN®.
  • Swallowing problems may last for several months. People who cannot
    swallow well 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 problems could make it unsafe for you to drive a car or do other
dangerous activities.
