SHIRE PLC: Elvanse(R): Positive European Outcome

Positive response from European regulatory procedure supports
approval of Elvanse®(lisdexamfetamine dimesylate) for ADHD 
NYON, Switzerland - 18 December 2012 - 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 
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 
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 
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) 
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 
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
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 
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
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)
