da MPS II usando a terapia de reposição enzimática.
Com
base nos resultados de testes realizados com pacientes de
MPS II, em 24/Julho/2006 o FDA - US Food and Drug Administration
- aprovou o uso nos Estados Unidos do ELAPRASE™
(idursulfase) produzido pelo laboratório Shire. O produto
deve ser lançado nos Estados Unidos nos próximos 30 dias.
Na Europa a solicitação de autorização foi feita em Dezembro
de 2005.
O
ELAPRASE™ (idursulfase) é o primeiro medicamento aprovado
para o tratamento por reposição enzimática de pessoas afetadas
pela Síndrome de Hunter (MPS-II). O produto é administrado
em infusões semanais.
Os
testes de Fase II/III conduzidos por 1 ano demonstraram que
foram obtidos importantes benefícios clínicos para os pacientes.
O tratamento foi bem tolerado pelos pacientes e as reações
mais comuns foram febre, dor de cabeça e dores nas articulações.

Shire’s
ELAPRASE™ (idursulfase) Approved by the Food and Drug Administration
(FDA) for Hunter Syndrome
Basingstoke,
UK and Philadelphia, US / July 24, 2006
Shire plc (LSE: SHP, NASDAQ: SHPGY, TSX: SHQ) today announced
that the FDA has granted marketing approval for ELAPRASE,
a human enzyme replacement therapy for the treatment of Hunter
syndrome, also known as Mucopolysaccharidosis II (MPS II).
Hunter
syndrome is a rare, lifethreatening genetic condition that
results from the absence or insufficient levels of the lysosomal
enzyme iduronate-2-sulfatase. Without this enzyme, cellular
waste products accumulate in tissues and organs, which then
begin to malfunction.
ELAPRASE
is the first and only treatment approved for people suffering
from Hunter syndrome. The product, which is given as weekly
infusions, replaces the missing enzyme that Hunter syndrome
patients fail to produce in sufficient quantities.
Shire
expects to launch ELAPRASE in the United States within the
next 30 days. “The FDA approval of ELAPRASE marks a significant
milestone in Shire’s effort to provide meaningful treatments
for patients suffering from genetic diseases,” said Matthew
Emmens, chief executive officer of Shire. “A hallmark of the
ELAPRASE program is the commitment demonstrated by patients
and families, investigators and Shire employees involved in
the development effort. We look forward to making ELAPRASE
available to patients in the coming weeks.”
“Regulatory
approval of ELAPRASE will enable physicians to move needy
patients beyond palliative care and make Hunter syndrome a
treatable disease,” said Joseph Muenzer, MD., Ph.D, of the
University of North Carolina at Chapel Hill. “Until today,
there were no options for addressing the underlying cause
of this devastating disease.”
Shire
submitted a Marketing Authorization Application (MAA) for
ELAPRASE to the European Medicines Agency (EMEA) on December
1, 2005. Based on average evaluation times, Shire anticipates
completion of the EMEA review by year end. In European countries
that have mechanisms for pre-approval access, Shire has also
submitted applications.
Clinical
Trial Results
A
53-week, randomized, double-blind, placebo-controlled Phase
II/III trial demonstrated that ELAPRASE provides clinically
important benefits to Hunter syndrome patients. The primary
efficacy endpoint of the trial was a composite analysis of
changes from baseline in two clinical measures: a 6-minute
walk test and percent predicted forced vital capacity. Shire
is pleased to report that this endpoint achieved statistical
significance compared to placebo.
After
one year of treatment, patients receiving weekly infusions
of ELAPRASE experienced a mean increase in the distance walked
in six minutes of 35 meters compared to patients receiving
placebo.
Safety
Data
Treatment
with ELAPRASE was generally well-tolerated by patients in
the Phase II/III trial. Adverse reactions were commonly reported
in association with infusions, and were generally mild to
moderate.
The
ELAPRASE label includes a boxed warning with information on
the potential for hypersensitivity reactions. The boxed warning
states that “Anaphylactoid reactions, which may be life threatening,
have been observed in some patients during ELAPRASE infusions.
Therefore, appropriate medical support should be readily available
when ELAPRASE is administered. Patients with compromised respiratory
function or acute respiratory disease may be at risk of serious
acute exacerbation of their respiratory compromise due to
infusion reactions, and require additional monitoring.”
In
all phases of clinical study for ELAPRASE, 11 patients experienced
significant hypersensitivity reactions during 19 of 8,274
infusions (0.2%) and no patients discontinued treatment permanently
as a result of a hypersensitivity reaction. The most common
adverse events observed in >30% of patients during the
Phase II/III trial were pyrexia, headache and arthralgia.
Fifty-one
percent (32 of 63) of patients in the weekly ELAPRASE treatment
arm in the pivotal clinical study (53-week placebo-controlled
study with an open-label extension) developed anti-idursulfase
IgG antibodies.
About
ELAPRASE
ELAPRASE
is a purified form of the lysosomal enzyme iduronate-2-sulfatase
and is produced by recombinant DNA technology in a human cell
line.
In
conjunction with the market approval of ELAPRASE, Shire Human
Genetic Therapies (the Shire business unit focused on genetic
diseases) has introduced a new product support center called
OnePathSM for the U.S market. OnePathSM is a single source
of product support for healthcare providers, patients and
their families, where personalized, comprehensive information
about ELAPRASE is available from a case manager. Case managers
can provide information about coding, reimbursement and insurance
verification, authorization letters, product access and treatment
center locations. OnePathSM also offers education about Hunter
syndrome and can refer patients to additional support services,
if needed.
Shire
Human Genetic Therapies is actively tracking health data among
individuals affected by Hunter syndrome as part of the company’s
long-term outcome survey, called the Hunter Outcome Survey
(HOS). HOS is designed to support the gathering, analysis,
reporting and sharing of data from around the world about
Hunter syndrome. Shire believes that the inclusion of all
people affected by Hunter syndrome and the analysis and dissemination
of this information will allow for further understanding of
Hunter syndrome and disease education on a global scale.

OnePath SM at 1 (866) 888-0660.
About
Hunter Syndrome
Hunter
syndrome (MPS II) is a serious genetic disorder mainly affecting
males that interferes with the body’s ability to break down
and recycle waste substances called mucopolysaccharides, also
known as glycosaminoglycans or GAG. Hunter syndrome is one
of several related lysosomal storage diseases.
In
Hunter syndrome, cumulative buildup of GAG in cells throughout
the body interferes with the way certain tissues and organs
function, leading to severe clinical complications and early
mortality. Physical manifestations for some people with Hunter
syndrome may include distinct facial features, a large head
and an enlarged abdomen. People with Hunter syndrome may also
experience hearing loss, thickening of the heart valves leading
to a decline in cardiac function, obstructive airway disease,
sleep apnea, and enlargement of the liver and spleen. In some
cases, central nervous system involvement leads to progressive
neurologic decline.
Shire
estimates that there are approximately 2,000 patients worldwide
afflicted with Hunter syndrome in areas where reimbursement
may be possible. Shires estimates that the U.S. accounts for
approximately 25% of the global market for Hunter syndrome.

company that focuses on meeting the needs of the specialist
physician. Shire focuses its business on attention deficit
and hyperactivity disorder, gastrointestinal, renal diseases
and human genetic therapies. The structure is sufficiently
flexible to allow Shire to target new therapeutic areas to
the extent opportunities arise through acquisitions. Shire
believes that a carefully selected portfolio of products with
a strategically aligned and relatively small-scale sales force
will deliver strong results.
Shire’s
focused strategy is to develop and market products for specialty
physicians. Shire’s inlicensing, merger and acquisition efforts
