Glaxo faces storm
over Seroxat

CLINICAL
auditors from Britain's medicines control agency are
expected to descend on Glaxo-SmithKline this week amid
concerns that the pharmaceuticals group may have
suppressed a series of negative studies on its key
antidepressant drug Seroxat, known as Paxil in the US.
In a highly
unusual move, a team from the Good Clinical Practice
unit of the Medicines and Healthcare Products Regulatory
Agency (MHRA) will demand access to all of GSK's files
and studies on Seroxat.
The decision
to take this dramatic step was taken following the
delivery to the MHRA of nine studies of Seroxat that
confirm the antidepressant can lead to suicidal
tendencies and other medical damage when administered to
people under the age of 18.
There has been extensive media
coverage of the potential harmful effects on young
people of Seroxat, one of GSK's leading compounds. But
until now the company has declined to acknowledge any
serious problems.
This week,
however, it will be asked by the MHRA to contact general
practitioners, letting them know of the potential
dangers to people under 18.
Sources at
GSK confirmed that an amendment to the instructions
carried with Seroxat was under discussion with the
authorities and an announcement would be made shortly.
There was no knowledge of the impending clinical audit.
Disclosure of
the regulatory concerns about Seroxat, which contributes
£1.5bn-£2bn of annual turnover to GSK, is likely to lead
to nervous selling on the stock market when it opens for
business today. Glaxo shares have recovered to 1258p
this year after falling below £10 in 2002.
Concerns that
clinical practices may have slipped at Britain's
flagship pharmaceuticals group will put additional
pressure on the company's chief executive Jean-Pierre
Garnier, who is already under fire over his possible
£22m severance package.
A senior
source at the MHRA told the Daily Mail that the decision
to conduct an audit at GSK was 'very, very unusual'.
'Normally we have a good relationship with these guys
and work closely together,' the source said.
If it were
found that critical studies had not been available to
regulators then GSK could eventually face criminal
charges under the Medicines Act.
Previous Good
Clinical Practice audits have been carried out at
second-line pharmaceutical groups where research
practices are sometimes less rigorous.
Members of
the Committee on the Safety of Medicines, the licensing
arm of the MHRA, were disturbed when they saw the
parallel Seroxat and placebo studies recently submitted
by GSK. They revealed a predilection to suicide,
aggressive behaviour and other psychosis in Seroxat
users under 18, which were not present in the placebo
studies.
The belief is
that a deep volume of research work showing
'contraindications in children' could not have been
carried out overnight and the appropriate regulatory
authorities should have been alerted much earlier - so
appropriate amendments could be made.
The big worry
for GSK now is that the disclosure of the disquiet at
the MHRA and its offshoots could attract the attention
of the Food & Drugs Administration in the US, which
works closely with the British regulators.
That could
seriously damage GSK's reputation in the US, where it
does much of its business and where Garnier has his
headquarters.
A spokesman
for GSK said: 'We can confirm we are in discussion with
the MHRA regarding proposed updates of the product
characteristics of Seroxat. However, it is not
appropriate to discuss this dialogue further until the
outcome of this review.
'Seroxat is
an important medication for treatment of anxiety and
depression, and has been for more than 10 years. It has
benefited the lives of millions of people suffering with
these serious conditions.'
A decision on
the safety of Seroxat/Paxil, and other widely prescribed
anti-depressants like Eli Lilly & Co's Prozac, will be
announced tomorrow, according to the UK Medicines
Control Agency. 'We will be making an announcement about
Seroxat tomorrow but we're not saying anything in
advance,' spokeswoman Alison Langley said.
Glaxo refused
to comment on whether a clinical audit was being carried
out, but confirmed it is in talks with the MHRA. 'We can
confirm we are in discussion with the MHRA regarding
proposed updates of the product characteristics of
Seroxat,' Glaxo's Martin Sutton said.
SEROXAT is
one of the biggest selling antidepressants in the world.
It treats depression, panic, obsessive compulsive
disorder, post-traumatic stress disorder, social anxiety
disorder and general anxiety disorder. Last year 400,000
people were prescribed the treatment, also known as the
'anti-shyness pill', in Britain alone.
