Positive Response from European Regulatory Procedure Supports
Approval of Elvanse® (lisdexamfetamine dimesylate) for ADHD
NYON, Switzerland, December 18, 2012 /PRNewswire/ --
Shire plc (LSE: SHP, NASDAQ: SHPG) today announces a positive
outcome from the European Decentralised Procedure (DCP) for
Elvanse® (to be known as Tyvense® in
Ireland). Elvanse is indicated as
part of a comprehensive treatment programme for attention
deficit/hyperactivity disorder (ADHD) in children aged 6 years of
age and over when response to previous methylphenidate treatment is
considered clinically
inadequate.[1]
The UK Medicines and Healthcare products Regulatory Agency
(MHRA) acted as the Reference Member State on behalf of seven other
European countries participating in the procedure (Denmark, Finland, Germany, Ireland, Norway, Spain
and Sweden). Product labelling has
been agreed by these countries, which will now issue their national
Marketing Authorisations (approvals); this typically takes a
further one to three months. In some countries, negotiations with
national pricing and reimbursement authorities will now be required
before the medicine is made available to patients, and the timing
for this process varies between countries.
Elvanse was accepted for review by the MHRA in January 2012, with the application based on two
European Phase 3 studies in children and adolescents with ADHD and
further supported by clinical data from the USA.[2],[3]
Elvanse is a long-acting, once daily medication for the control
of the symptoms of
ADHD.[2],[3]
Elvanse is the first of a new class of dopamine modulators approved
in Europe that uses pro-drug
technology to release the active drug in the body. It is currently
available in the USA and
Canada under the trade name
Vyvanse®, for the treatment of ADHD in children,
adolescents and adults, and in Brazil under the trade name
Venvanse®, for the treatment of ADHD in children aged 6
to 12 years. It is currently the most prescribed branded ADHD
medicine in the USA. The efficacy
and safety of Elvanse has been studied in many clinical trials and
Elvanse has been prescribed to treat more than 4 million patients
in the USA, Brazil and Canada.[4]
"We are delighted that the national approvals of Elvanse
in Europe are now imminent," said Angus Russell,
CEO, Shire. "ADHD is one of the most common psychiatric
disorders affecting children and adolescents. As all ADHD
patients are different and will vary in their responses to the
available treatments, we believe introducing Elvanse will provide
physicians with a broader range of options to help patients with
ADHD manage their individual needs effectively. We will
now work closely with the pricing and reimbursement authorities in
the respective countries to ensure that Elvanse is made available
to patients as soon as possible."
About Elvanse
Elvanse (lisdexamfetamine dimesylate) has not yet received
national marketing authorisation in each respective EU country
involved in the DCP, and national licenses are expected to be
issued one to three months after DCP closure. It is already
available in the USA and
Canada (brand name Vyvanse) and in
Brazil (brand name Venvanse),
where it has been used to treat over 4 million
patients.[4] Elvanse's efficacy
and tolerability have been studied in clinical trials both in the
USA and Europe.[2],[3],[5]-[11]
Elvanse is a single daily dose prodrug medication for the
treatment of ADHD. A prodrug is a substance that is ingested in an
inactive form and then activated within the
body.[12]
The inactive prodrug is absorbed from the gut into the
bloodstream where it is gradually converted to the active part of
the medicine, d-amfetamine
(d-AMF).[12] The active part
of Elvanse is thought to work by increasing the levels of
neurotransmitters (chemicals that are stored in nerve cells in the
brain and nervous system, which transmit messages between the nerve
cells) responsible for activity, attention and
concentration.[13]
Elvanse was developed with the goal of providing a long duration
of effect to help patients achieve control of their ADHD symptoms
throughout the day.[14]
Indication[1]
Elvanse is indicated as part of a comprehensive treatment
programme for attention deficit/hyperactivity disorder (ADHD) in
children aged 6 years and over when response to previous
methylphenidate treatment is considered clinically inadequate.
Treatment must be under the supervision of a specialist in
childhood and/or adolescent behavioural disorders. Diagnosis should
be made according to DSM-IV criteria or the guidelines in ICD-10
and should be based on a complete history and evaluation of the
patient. Diagnosis cannot be made solely on the presence of one or
more symptom.
The specific aetiology of this syndrome is unknown, and there is
no single diagnostic test. Adequate diagnosis requires the use of
medical and specialised psychological, educational, and social
resources.
A comprehensive treatment programme typically includes
psychological, educational and social measures as well as
pharmacotherapy and is aimed at stabilising children with a
behavioural syndrome characterised by symptoms which may include
chronic history of short attention span, distractibility, emotional
lability, impulsivity, moderate to severe hyperactivity, minor
neurological signs and abnormal EEG. Learning may or may not be
impaired.
Elvanse is not indicated in all children with ADHD and the
decision to use the drug must be based on a very thorough
assessment of the severity and chronicity of the child's symptoms
in relation to the child's age and potential for abuse, misuse or
diversion.
Appropriate educational placement is essential, and psychosocial
intervention is generally necessary. The use of Elvanse should
always be used in this way according to the licensed
indication.
About Elvanse Clinical Trials
The safety and efficacy of Elvanse was studied in two European
Phase 3 studies:
Study 325:[2]A randomised, double
blind, multicentre, parallel-group, placebo- and active-controlled,
dose-optimisation, safety and efficacy study in 336 children and
adolescents aged 6 to 17 years. Results of this study have been
accepted for publication in European Neuropsychopharmacology
and were also presented on October
21st 2011 at the American Academy of Child and
Adolescent Psychiatry (AACAP) congress in Toronto.
Study 326:[3]A Phase 3, double
blind, placebo-controlled, randomized withdrawal, multicentre,
extension, safety and efficacy study of lisdexamfetamine dimesylate
in 276 children and adolescents aged 6-17 with
attention-deficit/hyperactivity disorder. Results from this study
were presented on October
13th 2012 at the European College of
Neuropsychopharmacology (ECNP) congress in Vienna.
Misuse and
abuse[1]
Stimulants including Elvanse have a
potential for abuse, misuse, dependence, or diversion for
non-therapeutic uses that physicians should consider when
prescribing this product. Stimulants should be prescribed
cautiously to patients with a history of substance abuse or
dependence.

About ADHD
Attention Deficit Hyperactivity Disorder (ADHD) is one of the
most common psychiatric disorders in children and
adolescents[16],[17],[18]
and is recognised by the World Health Organization
(WHO).[19]
Globally, ADHD affects around 5% of children and
adolescents.[20] Based on this
prevalence rate, one can estimate that 5 million young people in
the EU are suffering from ADHD.
What causes ADHD?
While the exact origin of ADHD is not known, it is thought that
the disorder may be caused by an imbalance of neurotransmitters (or
chemicals in the brain).[21]
ADHD is thought to result from complex interactions between
genetic and environmental
factors,[22] with studies
estimating that genetic factors explain 60 to 75% of the aetiology
of
ADHD.[22],[23]
Environmental factors which may increase the risk of developing
ADHD include low birth weight/prematurity, maternal smoking during
pregnancy, and severe early psychosocial adversity (e.g. children
who have survived deprived institutional
care).[22]
