Public
and professional opinion about the pharmaceutical industry is
polarised. Some believe that drug companies are saints and, by
developing extraordinarily effective new medicines, they either save
lives or substantially improve people's quality of life. Others see the
industry as sinners, interested only in making profits for themselves
and their shareholders, and unconcerned with the welfare of patients. As
the title of Ben Goldacre's book indicates, he sides with the
“sinners”.
Goldacre's book is concerned
with describing many of the bad things that the pharmaceutical industry
has done over the past 20 years or so. In particular, Goldacre
criticises the industry's consistent, and continuing, failure to publish
the results of all its clinical research. He rightly includes not only
the failure to publish many clinical trials but also the findings from
early phase 1 studies in volunteers.
Such
criticisms, of course, are not new. Iain Chalmers, for example, has
written extensively about the failures of both industrial and academic
investigators to publish the results of clinical trials, leading, as a
result, to “publication bias”. The industry, in response to adverse
publicity in both the professional and lay media, have (albeit only in
part) responded. The International Federation of Pharmaceutical
Manufacturers and Associations (IFPMA) has thus, since 2009, required
member companies to disclose the results of clinical trials of products
that have been approved for marketing in at least one country. The fact
that pharmaceutical companies have made some attempt to “put their house
in order”, only because of external criticism, adds to the weight of
Goldacre's complaints. The IFPMA's position, however, still (at least
potentially) leaves unpublished those studies of products that either
fail to show benefit or are unsafe.
Goldacre
is equally critical of the industry's many and varied promotional
practices. In an overly long chapter on marketing, he gives special
attention to the multifarious approaches taken to “direct to consumer”
advertising in the USA. Anyone who has had the misfortune to watch
American television will have seen the pervasive drug adverts that
interrupt prime time shows. These adverts are presumably effective in
enhancing sales, although I find them just plain boring. In the USA,
almost the only developed country to allow direct to consumer
advertising, the phenomenon of “celebrity endorsement” has recently
emerged. More generally, Goldacre claims that the industry spends twice
as much on marketing as on research and development (R&D). Although
this may be true in the USA, it is not so in the UK. Under the
provisions of the Pharmaceutical Price Regulatory Scheme, companies can
only spend up to about 6% of their sales to the National Health Service
(NHS) on marketing, but up to 30% on R&D.
But
Goldacre's anger is directed not only at bad pharma. He also criticises
bad academia, bad drug regulators, bad patient advocacy groups, bad
journal editors, and bad doctors more generally. He even has a
(relatively modest) go at the UK's National Institute for Health and
Clinical Excellence (NICE).
Goldacre
accuses academics of not only failing to publish the results of their
own trials, but of conniving with pharmaceutical companies in the
selective reporting of the results of studies with which they have been
involved. There is no doubt that this has happened in the past, but the
extent to which it continues is unclear. Goldacre does though quote
evidence indicating that, in 2005, nearly two-thirds of 122 US medical
schools allowed clinical trial agreements with pharmaceutical companies
to be “confidential”; and about a half allowed sponsors to draft the
final report. The International Committee of Medical Journal Editors
insisted, in 2001, that the lead author of any study must confirm full
access to the data. He rightly accuses doctors, generally, to have
enjoyed—at least in the past—too much food and drink from drug companies
in return for a little gentle postgraduate education.
Drug
regulatory authorities, especially in the EU and the USA, are
criticised for their excessive secrecy, and for their continuing failure
to allow full disclosure of data on both the efficacy and safety of the
products they regulate. Goldacre is correct that UK regulatory
authorities have, in the past, been too reluctant to release data,
particularly information provided “in confidence” (at least partly for
alleged legal reasons). It is a pity though that he doesn't mention the
fact that in the UK the Medicines and Healthcare products Regulatory
Agency (MHRA) have made spontaneous reports of adverse reactions
available online for many years.
Goldacre
has some harsh words about patient advocacy organisations. He accepts
that they have an important role in bringing patients together,
disseminating information, and helping to lobby on behalf of the people
they represent. But when they obtain grants from drug companies to fund
their activities, the relationship can become complicated. As Goldacre
describes, patient advocacy groups have criticised NICE for the
decisions it has made about drugs of particular importance for their
members. It is right that they should do so, and I do not complain about
their activities in this context. What I do resent, and Goldacre
discusses this too, is the failure of these organisations to criticise
companies for the price they seek to charge from the UK's NHS. And I
particularly deplore the use of public relations firms, paid for by drug
companies, for lobbying actively on behalf of patient advocacy groups.
Nor
do the editors of journals escape Goldacre's ire. The pressure on
editors to publish articles about research sponsored by drug companies
is not so much about the advertising revenue (though that is
substantial) but about the reprint orders that are placed once a
particular article is published. A single published article of a study
sponsored by a drug company can bring in a reprint order of 100 000
copies (at perhaps US$2—5 a copy). Richard Smith (former editor of the BMJ), as well as The Lancet's own Richard Horton, deserve great credit for being honest about this issue in public.
There is much to praise in Bad Pharma,
but some readers might find the book too long and impenetrable. It is a
cross between scholarship, with numerous references to relevant
publications, and polemic. Few of the examples of drug companies'
malpractice in Big Pharma are new. Indeed, some attempts have
been made both by the industry, and by regulatory authorities, to
improve matters—although Goldacre has little confidence in these.
Goldacre
maintains that the literature on the effectiveness of modern drugs is
fatally flawed, because of the failures of drug companies to publish the
results of all the trials they have sponsored. As a consequence he
believes that many—perhaps most—of the products in regular use may lack a
rigorous evidence base. This is his explanation for the first sentence
of his book: “Medicine is broken”. Goldacre contends that only when drug
companies and regulatory authorities publish the full results of all
their past studies can the literature be cleansed of error. Apart from
the difficulties of even retrieving the final reports of studies
undertaken during the 1970s, 1980s, and 1990s, it is a reductio ad absurdum
to believe that the drugs originally licensed in that period, and still
in widespread use, are no better than placebo. Does anyone really
suspect that ibuprofen, statins, or angiotensin-converting-enzyme
inhibitors—to name just a few drugs introduced over the past 30
years—are no better than placebo?
In his
desire to paint drug companies and regulatory authorities in the worst
possible light, Goldacre omits salient facts from his discussion. There
is thus a long account of the reluctance of Roche to disclose the
results of some of the trials with its antiviral agent oseltamivir
(Tamiflu). But Goldacre does not mention that GlaxoSmithKline has
recently provided individual patient data on all its trials with their
own antiviral agent zanamivir (Relenza) to the Cochrane Collboration.
Goldacre also castigates the European Medicines Agency (EMA) for its
lack of transparency. In particular, he notes that neither its register
of clinical trials (EudraCT), nor its database of spontaneous reports of
suspected adverse reactions, are publicly available. Both, however, are
now publicly available online: EudraCT since 2011 and spontaneous
reports since June this year.
Whilst
Goldacre offers his own remedies, and some are sensible, he does not
seem to appreciate the extent of the culture change that is necessary.
This is not confined to expecting—as a default position—that the
entirety of the clinical data about a particular pharmaceutical product
is placed in the public domain. It is about expecting drug regulatory
authorities to be transparent about the reasons for reaching particular
decisions. This should involve, for a start, the advisory committees of
the EMA meeting in public. The US Food and Drug Administration does this
so why not the EMA and, come to that, the MHRA?
The
only organisation with the knowledge and skills to develop new
medicines is the pharmaceutical industry. We need to imbue an
environment that encourages the industry to develop new medicines.
Society, globally, desperately needs new medicines that provide the same
benefits for patients with malignant and neurodegenerative diseases as
the industry has so effectively done in the past for those with
cardiorespiratory disorders. The environment, therefore, needs to ensure
that the industry's creativity is appropriately rewarded. At the same
time, the industry's unacceptable practices that Goldacre describes in Bad Pharma
must be confined to history. It is this balance, between the beautiful
and the ugly, that Goldacre fails to achieve. As it stands Bad Pharma
is a book intended to shock the reader rather than propose eternal
verities. We need to find ways to enhance the industry's saintliness and
expiate its sins.
