Earlier
this year, the medical establishment was rocked when pharmaceuticals giant
GlaxoSmithKline reached a record-breaking $3bn settlement with US authorities
for illegally promoting drugs to treat conditions they weren't designed to fix.
So it didn't look good when, just a few months later, a GlaxoSmithKline sales
representative was found guilty of doing the same thing, with a different drug.
This time, the rep was pushing doctors to prescribe a blood disorder drug to
treat a bone marrow condition.
Unfortunately,
these were not isolated events. While some new reforms are being forced on big
pharma, shockingly poor regulation – especially in the US – means that
questionable and unethical practices still pervade an industry that is meant to
keep us healthy. Here are just a few of the dangerous trends at play in the
pharmaceutical drug business.
Lots of marketing, less research
Big pharma
justifies the exorbitant prices it charges for medicine with the argument that
the prices sustain expensive and innovative research and development operations
– even as the rate of R&D breakthroughs has plummeted and companies have
slashed their R&D workforces.
But in the
US the industry is thought to spend almost twice as much on marketing as it
does on R&D. Academics estimated that the industry spent $57.5 billion
promoting their drugs in 2004, mainly by pushing them to doctors, or about
$61,000 per physician. That's a full 24.4% of US sales revenue, as opposed to
just 13.4% spent on R&D.
Pharmaceutical
companies often lavish doctors with free conferences, meals and drug samples –
all of which are designed to make a doctor more likely to prescribe their
product. And studies show this money works. On top of that, companies actually
buy prescription records from pharmacies so they can individually track
doctor's prescription records – and use this to tailor their marketing and
promotion to the doctor.
As cynical as
these profit-driven moves are, there is some hope. Beginning next year
pharmaceutical companies will be required to disclose all payments above $10 to
physicians – part of the reforms included in President Barack Obama's signature
Affordable Care Act. Although there's a world of difference between requiring
these payments to be disclosed and outlawing them, it's an important first
step.
Bury the data
To get
their drugs approved by regulators, and to persuade doctors to prescribe them,
big pharmaceutical companies rely heavily on clinical trials. This creates
serious problems for consumers.
To begin
with, published trials funded by pharmaceutical companies are more likely to be
favourable to the sponsor than other studies. This usually isn't because they
are rigging the results – it's because they only publish the trials that suit
them.
Dr Ben
Goldacre describes how it works with a personal recollection in his recent
book, Bad Pharma: How Drug Companies Mislead Doctors and Harm Patients:
Seven
trials had been conducted comparing reboxetine against a placebo. Only one ...
had a neat, positive result, and that one was published in an academic journal,
for doctors and researchers to read. But six more trials were conducted, in
almost 10 times as many patients. All of them showed that reboxetine was no
better than a dummy sugar pill. None of these trials was published ...
With
between two-thirds and three-quarters of trials published in major medical
journals funded by the industry, this is a major problem.
And it gets
worse. Many drug companies conduct their testing in developing countries where
regulations are poor – and sometimes the people they experiment on die in the
process. A BBC investigation revealed last month that drug companies have
tested experimental drugs on thousands of poor Indians without their knowledge
or consent. Over the last four years, over 2,000 people have died in the
process – generally without any compensation for their families.
Activists
and lawyers in India are investigating the abuses, buoyed by the press
attention. Hopefully that will help fuel the push for more transparent clinical
trials. GlaxoSmithKline, fingered in the BBC report, has said it will open up
much of its clinical trial data to other researchers. It's too early to tell
whether they'll live up to the commitment, but as this is the first major
pharmaceutical company to move this move it's an encouraging sign.
Finding new users
Learning
new ways to market old drugs is one of the industry's favourite tricks. Take
the case of powerful antipsychotic drugs designed to treat schizophrenia and
bipolar disorder that are now routinely prescribed to treat mild mood
disorders, insomnia and emotional discomfort. Two antipsychotic drugs are now
the fifth and sixth best-selling prescription drugs in the US: 3.1 million
Americans regularly use an antipsychotic medication.
A UK
government review found that 1,800 people died needlessly in nursing homes due
to the overuse of antipsychotics on dementia patients. As usual, this
over-prescription didn't just happen. In the US, Johnson & Johnson
reportedly reached a $2.2bn settlement with the government after it was caught
paying tens of millions in kickbacks to medical professionals to increase sales
of its drugs in nursing homes, including over $100m in antipsychotic drugs.
Quick
growth in the use of drugs to treat new conditions generally involves
"off-label" use – using a drug to treat a condition federal
regulators have not approved it for. Companies are not allowed to market their
drugs for these purposes – but they don't always follow the rules. Earlier this
year, in the largest settlement ever for the industry, GlaxoSmithKline agreed
to pay a $3bn fine for marketing its antidepressants for use as a weight loss
aid and to treat sexual dysfunction. But the company cashed in tens of billions
selling these drugs – making the fine little more than an additional business
cost.
Towards a healthy industry
There are
countless aspects of the drug development and marketing business that need to
be investigated and reformed. For a start, we urgently need more unbiased
clinical trials, stronger consumer protections, more costly punishment for
malfeasance, and greater access to affordable medicines in developing countries
– still a long way off.
All too
often, the industry remains one of the key blockers of reform, and it's not
hard to understand why. For them, the current system works very well: in 2011,
the 10 largest US drug companies took more than $43bn in profits.
In the face
of these giant challenges, there are small but real signs of hope. The
Affordable Care Act fought for and passed in the US, and the decision by
GlaxoSmithKline – under pressure – to publish more of their trial data
demonstrate that things can change. But much more is needed. The industry built
to keep us healthy is still sick – but at least we know what ails it.
