Last week
I posted a review of Ben Goldacre's new book,
Bad Pharma: How Drug Companies Mislead Doctors and Harm Patients (reviewed in
The Economist). This weekend
The Guardian (UK) posted an interview with Goldacre about his new book, and many of the questions comes from readers.
Ben
Goldacre's first book, Bad Science, shredded the claims of homeopaths
and fake doctors. For his second he has his sights trained on the
pharmaceutical industry. Here he answers your questions.

The blindingly obvious inference of the extract from your book published in the Guardian– as of so many others you once commendably wrote in your Bad Science column
– is that this is an industry totally unsuited to being run on
profit-maximising lines by conventional shareholder companies. Given
that, and the tremendous level of subsidy the industry already receives
from governments around the world, why not spell out the vital necessity
of locating it within publicly owned/non-profit organisations where
there need be no obstacle to full transparency?

I am a realist
about this. I don't want a central-command state economy. In general,
drug companies are reasonably good at developing new treatments and
there's also a lot of good in the industry. The point of my book is that
it's possible for good people in badly designed systems to perpetrate
acts of great evil completely unthinkingly. I don't think any of the
people I write about would punch an old lady in the face, but they would
inflict the same level of harm when they are abstracted away from the
outcomes of their actions.
This is made easier, I think, because in general, most drugs
do work better than nothing: it's just that we may be misled into
using, for example, an expensive new drug where an older, cheaper one is
more effective.
Overall, the problem is we don't have a competent
regulatory framework that prevents things from going horribly wrong. If
companies are allowed to hide the results of clinical trials then they
will, and that will distort clinical practice. Doctors and patients will be misled and make sub-optimal decisions about what treatment is best for them.
Similarly,
if you can get on to the market by making a me-too copycat drug that
represents little or no therapeutic advance and is even less effective
than the drugs that it copies, then you will. And you can get such a
drug to the market because regulators approve new treatments even when
they've only been shown only to be better than placebo…
The Observer: Rather than the best current treatment available?
Exactly.
When that happens, then there's less drive to innovate new medicines.
So a lot of people think they know how you test a new drug, they think
it's a placebo-controlled randomised trial, and that's kind of true.
However, for most situations we already have some kind of treatment, so
we're not interested in whether your treatment is better than nothing;
we're interested in whether it's better than what we're already using.
But you can get on to the market without ever comparing your drug
against the best currently available treatment, and then you can
bamboozle doctors and patients into using it by distorting the clinical
evidence with all the tricks I describe, and then by giving a biased
picture of that distorted evidence to doctors and patients through your
marketing activity. All of that means, crucially, you can turn a profit
by producing drugs that aren't very innovative.
So at the moment
our regulatory frameworks do not represent a good set of incentives for
innovation. When people say, "Oh my God, it's dreadful all these
companies have had to pull out of developing new drugs for Alzheimer's",
on the one hand Alzheimer's is a very difficult problem, on the other
hand we haven't created a regulatory framework that sufficiently
incentivises people to take serious risks, and research entirely new
treatments.
I have been in healthcare marketing
communications for more than 30 years (flogging drugs to doctors) and
can confirm that much of the sharp practice you describe is caused by
the pressure exerted on researchers by marketing departments. When a new
drug entity makes it through Phase I, the pharmaceutical company's
marketers carry out market research studies to find out what doctors
expect and desire from such a product. The results of these studies are
used to develop "guidance" for researchers designing Phase II and III
trials. One issue is the speed with which some doctors ("innovators" in
marketing speak) adopt new medicines. There is a drug surveillance
system in this country that requires doctors to report all adverse
events occurring in patients taking new drugs. So if doctors were a
little less enthusiastic and prescribed new products to no more than a
couple of patients at first, most problems would come to light before
large numbers were affected.

I
agree, the world would be a better place if doctors were less
enthusiastic about adopting very new drugs. When I was taught how to
prescribe by my clinical pharmacology professors, as an undergraduate in
medicine, we were told: don't prescribe new drugs unless they are
spectacularly superior to what you already have; let other doctors take
the chance. And that's what I teach students myself. Regard the whole of
the rest of humanity as unpaid stunt doubles. Because, when you
prescribe a new drug, often you are prescribing something that has only
been tested in a few thousand people for a very short period of time,
perhaps only six months, and that's not long enough to know whether
there are any medium- or long-term side-effects. It's also too few
recipients of the drug to find out about rarer side-effects. On top of
that, when drugs come to market they've only often been shown to be
effective on short-term outcomes, and on surrogate outcomes, weak
outcomes, theoretical outcomes. So a new drug might have shown to affect
a blood test result, which we hope is theoretically associated with a
real-world outcome, but not tested against real-world outcomes such as
pain, suffering and death. On top of that, while doctors and patients
sometimes fetishise the new, the evidence is that overall, new drugs are
often no better than the older ones they replace.
If there is
time for shared decision making, when we're prescribing a new drug, then
I think first doctors could maybe say to their patients: "The drug I'm
prescribing has only been tested in a few thousand people for less than
six months, and it's only been shown to improve blood tests, not the
real outcomes in your disease. If you prefer, we also have a tablet that
has been around for 10 years, has been taken by millions of people, and
that we know has a positive impact on real-world long-term outcomes –
which would you prefer?" Because I think these are reasonable issues to
factor in, when you're making a treatment decision.
Obs: And the point about marketing departments influencing trials?
This
is a really interesting area and it's a good illustration of how there
is good and bad in current marketing practices. I think it's really good
that somebody out there listens to what doctors and patients want and
need, in order to try to address those needs. There's a scandalously
brief and interesting history of research on this question in academia.
It was only very recently that people went out and formally asked
patients: "What's the most important outcome to you?" The classic study
was one in a rheumatology outpatients' clinic – they said: "What kind of
trials do you think need to be done?" And the patients said: "We don't
think you need any more trials comparing one pill against another, we
want trials to tell us if physiotherapy improves outcomes, because doing
physio is a massive drag and requires a lot of effort from us." The
other thing they said, to everybody's complete astonishment, was: "We
don't think that pain is the most important symptom, it's actually
stiffness." And that amazed everyone. So good quality, systematic, mixed
methods, qualitative and quantitative research, to find out this sort
of stuff is really great and important.
Obs: Are pharma marketing departments doing that?
Well,
they're probably doing some and a mix of other stuff. The real problems
come when you look at the interplay between market research and the
whole process of publication planning, which is something that many
doctors and academics are completely unaware of. Certainly, I think, the
public have very little knowledge of it. We all like to imagine that
the academic literature is composed of worthy papers by independent
academics exploring things on the basis of interest. We don't, for the
most part, realise that there is often a hidden hand guiding this
process. So when a new drug is being brought to market, especially one
that addresses a problem that hasn't been addressed before, you will
often get an elaborate sequence of covertly planned marketing activity
in the academic literature, without any declaration that this is what's
happening.
For example, companies will set about paying for and
planning, and in some cases ghostwriting, papers saying that the disease
their new drug treats is an underdiagnosed problem, it's much more
prevalent than we thought. You might also start to produce lots of
literature about how current interventions aren't very good, downplay
your own side effects, promote off-label uses of your drug, and so on.
That's all before you get anywhere stage-managing the literature about
the actual benefits of your treatments.
So the interplay between
marketing departments and research departments, I think, is inevitable.
It's a mixture of good and bad, but the thing that's most striking is
how ignorant most people are about these things, and how huffy and upset
drug companies get when you start to talk about it. If people really
think it's OK to have commercial medical writers writing papers instead
of academics, then they should put their names clearly and proudly at
the top of the papers. If people really think it's OK to stage-manage
the whole programme of academic journal articles behind the scenes up to
the launch of your drug, they should just mention that in the papers at
the bottom: "This is part of the programme leading up to the launching
of drug X. The idea for this paper came from the marketing department at
Y." If they think all this activity is OK, then that's fine: they
should be happy to declare that publicly, and we can decide for
ourselves.
In your book you appear to be describing
situations where companies knowingly suppress information that shows the
products they are selling are ineffective or worse. My doctorate is in
engineering and if we had done that we would have been liable to a
prosecution for fraud. This is quite irrespective of the regulations
pertaining to a specific industry, though we were required to report any
significant deviation to the regulator as soon as we were aware of it.
So, quite simply, why are these pharmaceutical companies not being
prosecuted?
~ Joseph Cullen, via email
Well,
it's a huge cultural blind spot. No one, with the exception of the
Faculty of Pharmaceutical Medicine, which is a very small organisation,
not one of the medical and academic bodies have stood up and said:
"Selectively withholding unflattering trial data is research misconduct,
and the ultimate end product is a biased picture of the effectiveness
of your intervention."
If I deleted half the data points in one
study to make my treatment look better than it really is, everybody
would say that was research misconduct. But for some reason when I
delete half of the trials from my clinical trials programme and only
publish half of them, that is not regarded as research misconduct.
It's
a cultural blind spot that comes about, I think, because the
misconduct arises from a slightly diffused network of failure. So in
some cases there will be obsessive, evil people at the centre, with full
panoramic knowledge of everything that's happening, stage managing it.
In other cases, you'll have individuals in organisations, maybe quite
junior, they've got a trial with a negative result, nobody's
enthusiastic about putting it out there, and to that one researcher,
not publishing a paper intuitively doesn't feel the same as deleting
some data points in a study, even if the end product is the same, in
terms of the impact on doctors' and patients' knowledge of the risks and
benefits.
That's why I think it's really disappointing that
nobody, not the Royal Colleges, the Academy of Medical Sciences, the
British Pharmacology Society, the British Medical Association, none of
these organisations have stood up and said: selective non-publication of
unflattering trial data is research misconduct, and if you do it you
will be booted out. And I think they really urgently should.
I
have to say, for a lot of the things I cover in the book, I honestly
believe this stuff has been protected from public scrutiny for many
years by a wall of tedium, or if you like, by a wall of modest
scientific complexity. It's behind closed doors but not locked doors,
it's all hiding in plain sight. I think it's very likely that this will
turn out to be like MPs' expenses or phone hacking journalists. The
people involved in these small communities have all convinced one
another that what they do is completely normal and fine. But it's not. I
think that when the public come to see what has been going on, they
might be appalled.
I work for an institutional
shareholder of many large pharmaceutical companies. Do you think there
are any pharmaceutical companies that stand out in terms of transparency
of trial results? And at the other end of the scale, are there any
companies that consistently fail to publish negative trials?
~ Laura Foll, analyst, Henderson Global Investors
No.
I have no reason to believe that any one is any better than the other.
If you have bad regulations, incoherently enforced, then everybody does
what they have to do, to succeed in the marketplace.
Considering we have to discuss and explain population-based risk to the
individual we are treating, and the way we discuss risk biases the
response, how do you discuss risk in simple terms, for example, in
primary prevention?
~ Tariq Hussain, GP
This
is an amazingly interesting area, and I think it is the next horizon in
medicine. If you put me in charge of the medical research budget I
would cancel all primary research, I would cancel all new trials, for
just one year, and I would spend the money exclusively on making sure
that we make the best possible use of the clinical evidence that we
already have. This means first devising better ways of communicating
risk to patients, and engaging in a process of shared decision-making
wherever appropriate. Second, I would put the money into a better
information architecture for evidence-based medicine. I would put the
money into researching and implementing better systems to get the right
information to the right doctor at the right time, to collate and then
to disseminate the information that we have.
Obs: We had
quite a few questions from readers who, faced with difficult decisions
about changing drugs or trying a new drug, were reading trials and
studies themselves…
That's a real mistake, actually. As I
say in the book, I don't think it's a good idea for individuals to try
to pick and choose their drugs, or stop their drugs. I think it's a very
dangerous business. I don't say that because I want to protect any
special status in the medical profession, I just think it takes a really
long time to acquire the skills and knowledge to do that. People often
say: "What do I do for me? For my treatment decision right here and
now?" And the best advice I can ever give is to find a good doctor and
talk to them about it, and anybody who tells you that they can give good
advice about your medical problems in a newspaper article, or on the
internet, or in some silly magazine, should be regarded with infinite
suspicion, no matter how big a bouffant or how deep a perma-tan they
have – I'm not thinking of anyone in particular, I don't really know
that scene. I don't do readers' health advice and I think these things
are best discussed with your doctor.
Patients often resort to saying: "Doctor, if it were you, what would you do?" Or "If it were your child…?"
I
think that's a reasonable question to ask. Often decision making is a
complicated business, weighing lots of risks and benefits against one
another, often it can't be operationalised. But I think the important
thing is that doctors have all of the information that they need in
order to make informed decisions. First, because it's not hidden from
them, and second because it is competently disseminated to them, and
patients should have the choice to engage with that, but there's nothing
compulsory about it. I think data on how good your local school is
should be available to you, but equally I recognise that the
overwhelming majority of parents never look at it, and that's normal. I
wouldn't judge them. I just think the information needs to be available.
