Ipsen demonstrates leadership position in neurotoxin research with strong presence at TOXINS 2019

PARIS–(BUSINESS WIRE)–Regulatory News:

Ipsen (Euronext: IPN; ADR: IPSEY) today announced that
abobotulinumtoxinA (Dysport®) and its recombinant botulinum
toxins pipeline are the subject of 50 posters at the 2019 TOXINS
International Conference. Results are presented from basic science (in
, in vitro, ex vivo, in silico), to
clinical (Phase I to IV) and patients and caregivers surveys. Data
highlights include further differentiation of Dysport® in the
treatment of spasticity and movement disorders1, results from
the first in-human study of a recombinant neurotoxin (rBoNT-E), real
life data (ULIS-III) as well as a survey with insights from patients and
caregivers on the burden of spasticity (Carenity).

Our data at TOXINS 2019 further differentiate Dysport®
in the treatment of spasticity and other movement disorders, and
demonstrate the headway we are making with our innovative pipeline,
including new recombinant botulinum toxins such as our fast-acting
” said Alexandre Lebeaut, Executive Vice President, R&D
and Chief Scientific Officer, Ipsen
. “We look forward to many
more years of real and significant progress toward our commitment to
improving people’s lives through innovative and effective treatments and
by transforming the treatment paradigm with tailored approaches

With Dysport® (abobotulinumtoxinA), Ipsen offers a single
product to treat a range of therapeutic indications2.
Injected at approved doses, the amount of active neurotoxin in Dysport®
(data3 published in Toxins, in December 2018) may help to
explain the long-lasting symptomatic relief observed in clinical studies
(based on phase 3 trials4,5) within a well-characterized
safety and tolerability profile. With a long duration of response,
Dysport® aims at providing an answer to the unmet need of
patients and their families.

Alexandre Lebeaut added: “We are proud and excited to be
presenting these new data at TOXINS 2019 as we continue to build on more
than 30 years of clinical experience with Dysport
We will continue investing in this unique product through research and
novel programs studies to further explore its potential and address
patients’ unmet needs.”

About TOXINS conference

Held every 2 years, TOXINS is a key event for experts – clinicians and
researchers from academia and industry – in the field of neurotoxins and
especially Botulinum toxins. The international congress will take place
in 16-19 January 2019, in Copenhagen, Denmark. The TOXINS 2019
scientific program will feature presentations on the latest developments
in the basic science and clinical applications of neurotoxins.

About spasticity and cervical dystonia

Spasticity is a condition in which there is an abnormal increase in
muscle tone or stiffness in one or more muscles, which might interfere
with movement. Spasticity is usually caused by damage to nerve pathways
in the brain or spinal cord that control muscle movement, and may occur
in association with cerebral palsy, spinal cord injury, multiple
sclerosis, stroke, and brain or head trauma 8.

With a prevalence of 4.98/100,000 in Europe, cervical dystonia is the
most common adult-onset focal dystonia, a movement disorder
characterized by involuntary and sustained muscle spasms9.
Also known as spasmodic torticollis, cervical dystonia is an idiopathic
chronic condition in which the neck is twisted or deviated.

About Dysport®

Dysport® is an injectable form of a botulinum neurotoxin type
A product, which is a substance derived from Clostridium bacteria
producing BoNT-A that inhibits the effective transmission of nerve
impulses and thereby reduces muscular contractions6. It is
supplied as a lyophilized powder. As of 31 December 2018, Dysport®
had marketing authorization in more than 85 countries and more than 30
years of clinical experience7.

NOTE: Dysport® labels and approved indications may vary from
country to country


Dysport® is approved for the treatment of adult upper and
lower limb spasticity, paediatric lower limb spasticity and cervical
dystonia (referred to spasmodic torticollis in some markets) in many
international markets. Please refer to national labelling for details of
the locally approved prescribing information in each of these

Adverse effects resulting from the distribution of the effects of the
toxin to sites remote from the site of administration have been
reported. Patients treated with therapeutic doses may present with
excessive muscle weakness. The risk of occurrence of such undesirable
effects may be reduced by using the lowest effective dose possible and
by not exceeding the maximum recommended dose. Very rare cases of death,
occasionally in the context of dysphagia, pneumopathy (including but not
limited to dyspnoea, respiratory failure, respiratory arrest) and/or in
patients with significant asthenia have been reported following
treatment with botulinum toxin A or B. Patients with disorders resulting
in defective neuromuscular transmission, difficulty in swallowing or
breathing are more at risk of experiencing these effects. In these
patients, treatment must be administered under the control of a
specialist and only if the benefit of treatment outweighs the risk.
Dysport® should be administered with caution to patients with
pre-existing swallowing or breathing problems as these can worsen
following the distribution of the effect of toxin into the relevant
muscles. Aspiration has occurred in rare cases and is a risk when
treating patients who have a chronic respiratory disorder. Dysport®
should only be used with caution and under close medical supervision in
patients with clinical or sub-clinical evidence of marked defective
neuro-muscular transmission (e.g. myasthenia gravis). Such patients may
have an increased sensitivity to agents such as Dysport®,
which may result in excessive muscle weakness. Caution should be
exercised when treating adult patients, especially the elderly, with
focal spasticity affecting the lower limbs, who may be at increased risk
of fall. In placebo-controlled clinical studies where patients were
treated for lower limb spasticity, 6.3% and 3.7% of patients experienced
a fall in the Dysport® and placebo groups, respectively. The
recommended posology and frequency of administration for Dysport®
must not be exceeded. Patients and their care-givers must be warned of
the necessity to seek immediate medical treatment in case of problems
with swallowing, speech or respiratory problems. For the treatment of
spasticity in children, Dysport® should only be used in
children 2 years of age or over. As with any intramuscular injection,
Dysport® should only be used where strictly necessary in
patients with prolonged bleeding times, or infection/inflammation at the
proposed site(s) of injection. Dysport® should only be used
to treat a single patient, during a single session. Any unused product
remaining should be disposed of in accordance with Special Precautions
for Disposal and Handling. Specific precautions must be taken during the
preparation and administration of the product and the inactivation and
disposal of any unused reconstituted solution. This product contains a
small amount of human albumin. The risk of transmission of viral
infection cannot be excluded with absolute certainty following the use
of human blood or blood products.”

Forward Looking Statement

The forward-looking statements, objectives and targets contained herein
are based on the Group’s management strategy, current views and
assumptions. Such statements involve known and unknown risks and
uncertainties that may cause actual results, performance or events to
differ materially from those anticipated herein. All of the above risks
could affect the Group’s future ability to achieve its financial
targets, which were set assuming reasonable macroeconomic conditions
based on the information available today. Use of the words “believes”,
“anticipates” and “expects” and similar expressions are intended to
identify forward-looking statements, including the Group’s expectations
regarding future events, including regulatory filings and
determinations. Moreover, the targets described in this document were
prepared without taking into account external growth assumptions and
potential future acquisitions, which may alter these parameters. These
objectives are based on data and assumptions regarded as reasonable by
the Group. These targets depend on conditions or facts likely to happen
in the future, and not exclusively on historical data. Actual results
may depart significantly from these targets given the occurrence of
certain risks and uncertainties, notably the fact that a promising
product in early development phase or clinical trial may end up never
being launched on the market or reaching its commercial targets, notably
for regulatory or competition reasons. The Group must face or might face
competition from generic products that might translate into a loss of
market share. Furthermore, the Research and Development process involves
several stages each of which involves the substantial risk that the
Group may fail to achieve its objectives and be forced to abandon its
efforts with regards to a product in which it has invested significant
sums. Therefore, the Group cannot be certain that favorable results
obtained during pre-clinical trials will be confirmed subsequently
during clinical trials, or that the results of clinical trials will be
sufficient to demonstrate the safe and effective nature of the product
concerned. There can be no guarantees a product will receive the
necessary regulatory approvals or that the product will prove to be
commercially successful. If underlying assumptions prove inaccurate or
risks or uncertainties materialize, actual results may differ materially
from those set forth in the forward-looking statements. Other risks and
uncertainties include but are not limited to, general industry
conditions and competition; general economic factors, including interest
rate and currency exchange rate fluctuations; the impact of
pharmaceutical industry regulation and health care legislation; global
trends toward health care cost containment; technological advances, new
products and patents attained by competitors; challenges inherent in new
product development, including obtaining regulatory approval; the
Group’s ability to accurately predict future market conditions;
manufacturing difficulties or delays; financial instability of
international economies and sovereign risk; dependence on the
effectiveness of the Group’s patents and other protections for
innovative products; and the exposure to litigation, including patent
litigation, and/or regulatory actions. The Group also depends on third
parties to develop and market some of its products which could
potentially generate substantial royalties; these partners could behave
in such ways which could cause damage to the Group’s activities and
financial results. The Group cannot be certain that its partners will
fulfil their obligations. It might be unable to obtain any benefit from
those agreements. A default by any of the Group’s partners could
generate lower revenues than expected. Such situations could have a
negative impact on the Group’s business, financial position or
performance. The Group expressly disclaims any obligation or undertaking
to update or revise any forward looking statements, targets or estimates
contained in this press release to reflect any change in events,
conditions, assumptions or circumstances on which any such statements
are based, unless so required by applicable law. The Group’s business is
subject to the risk factors outlined in its registration documents filed
with the French Autorité des Marchés Financiers. The risks and
uncertainties set out are not exhaustive and the reader is advised to
refer to the Group’s 2017 Registration Document available on its website
