European Committee Issued Positive Opinions to Extend Indication for PREVENAR to Include Pneumonia and Otitis Media

    MADISON, NJ, March 1 /CNW/ - Wyeth Pharmaceuticals, a division of Wyeth
(NYSE:   WYE), has received two positive opinions recommending approval for an
extension of the indication for PREVENARTM (Pneumococcal Saccharide Conjugated
Vaccine, Adsorbed) to the European market by the Committee for Medicinal
Products for Human Use (CHMP). The opinions recommend extending the
indications of PREVENAR to include active immunization against pneumonia and
acute otitis media (middle ear infection) caused by vaccine serotypes.
PREVENAR is currently approved for active immunization of children from 2
months to 5 years of age against sepsis, meningitis, bacteraemic pneumonia and
bacteraemia caused by Streptococcus pneumoniae serotypes 4, 6B, 9V, 14, 18C,
19F and 23F. Pneumococcal disease is a significant concern to children's
health, estimated to result in more than one million deaths each year in young
children around the world.
    "S. pneumoniae is the leading cause of bacterial pneumonia in humans
beyond the first few weeks of life and is a major cause of death and illness
worldwide," says Peter Paradiso, Vice President, Scientific Affairs, Wyeth
Vaccines. "It also is an important cause of acute otitis media, which if left
untreated, may lead to more serious diseases such as mastoiditis and
meningitis. We welcome the CHMP's recommendation for both new indications in
the EU which, if approved, will underscore the value of PREVENAR in helping to
protect infants and young children from common pediatric illnesses caused by
S. pneumoniae."
    PREVENAR is the first and only conjugate vaccine shown to be effective in
reducing the incidence of pneumococcal disease (PD) in infants and toddlers.
The CHMP recommendations of PREVENAR will now be forwarded to the European
Commission (EC) for final approval, which is anticipated in the second quarter
of 2007.
    Many health authorities have recognized the importance of protecting
infants and young children against pneumococcal disease. PREVENAR is a part of
the routine national childhood immunization schedule in 16 countries
worldwide, including Belgium, France, Germany, Greece, Italy, Netherlands and
the United Kingdom (UK).

    About Pneumonia

    Pneumococcal pneumonia is an infection of the lungs caused by the
bacterium Streptococcus pneumoniae. There are many causes of pneumonia,
including bacteria, viruses and other pathogens. When S. pneumoniae invades
the lungs, the body's immune system responds, generating an inflammatory
response. White blood cells, fluid and cellular debris then fill the air
spaces of the lower respiratory tract causing physical symptoms such as
coughing, fever and shortness of breath.
    In prelicensure clinical trials, PREVENAR was found to be 97.4 percent
(95% CI: 82.7-99.9) efficacious in preventing serotype-specific invasive
pneumococcal infections in infants who were fully vaccinated and 89.1 percent
(95% CI: 73.7-95.85) efficacious for all cases of invasive pneumococcal
disease regardless of serogroup. Importantly, in this clinical study, PREVENAR
was effective in reducing the incidence of radiographically-confirmed
pneumonia in children younger than two years of age by 23.4 percent (95% CI:

    About Otitis Media

    Acute otitis media (AOM) is a common childhood disease with important
ramifications to the overall health of infants and young children. The peak
incidence of AOM occurs at 6 to 18 months of age, but it can also occur in
older children. Complications of AOM include persistent middle ear effusion,
chronic otitis media, transient hearing loss, or speech delays.
    PREVENAR has been shown to have an impact on AOM; in a clinical study,
PREVENAR reduced vaccine serotype cases of AOM by 57 percent (95% CI: 44-67),
cases of culture-confirmed pneumococcal AOM by 34 percent (95% CI: 21-45) and
all cases of AOM by 6 percent (95% CI: -4-16).
    In the United States, a study found that following the introduction of
PREVENAR, otitis media outpatient visit rates declined by 20 percent in
children aged less than two years, representing 246 fewer otitis media visits
per 1,000 children in the United States.

    About Pneumococcal Disease

    Pneumococcal disease describes a group of illnesses caused by the
bacterium Streptococcus pneumoniae, also known as pneumococcus. This bacterial
pathogen, which affects both children and adults, is a major cause of death
and illness worldwide. In fact, according to the World Health Organization
(WHO), pneumococcal disease is the number one vaccine-preventable cause of
death in children younger than 5 years of age worldwide.

    Important Safety Information about PREVENAR

    In clinical trials (n = 18,168), the most frequently reported adverse
events included injection site reactions, fever (greater than or equal to 38
degrees C/100.4 degrees F), irritability, drowsiness, restless sleep,
decreased appetite, vomiting, diarrhea and rash.
    Risks are associated with all vaccines, including PREVENAR.
Hypersensitivity to any vaccine component, including diphtheria toxoid, is a
contraindication to its use. PREVENAR does not provide 100 percent protection
against vaccine serotypes or protect against nonvaccine serotypes.
