Truth in clinical research trials involving pharmaceutical
sponsorship
Large clinical trials are expensive to mount. Funding comes mainly
from pharmaceutical companies seeking information on drug efficacy
and adverse events. Patients should be informed of the financial and
publication agreements reached between those conducting the
trials. This is unlikely to have a significant effect on trial
participation and will provide patients with information relevant
to informed consent. A small proportion of monies raised from drug
trials could be set aside to fund both a trial register site and further
studies on adverse drug reactions.

In recent years, economic rationalism has forced public
institutions to look for non-governmental sources of income and
links with industry.1
Our dermatology department needed equipment for which funds were not
available from the hospital budget, but would be available from
payment for participating in a drug trial. The trial sponsors wished
to compare their product with the current "best" cream and a placebo in
a randomised controlled trial. Participation would be voluntary,
the risk of harm minimal, privacy would be protected and patients
would be "suitably informed".
An administrative and financial agreement was arranged between our
department and the professional contract research organisation
responsible for the study. Details of this trial are shown in the Box.
There was some pressure for quick approval, as doctors working from
their private rooms had an impressive head start and were already
entering patients in the trial. Our institutional ethics committee
sought a number of changes to the trial protocol, but it was eventually
approved. We had no sooner entered patients into the trial than it was
closed: the required number of patients had been supplied by private
practitioners. Was this a case of a public institution being too slow
in responding to the demands of industry?
Perhaps, but there were other, more important issues, particularly
those relating to restrictions of intellectual property, the
opportunities for publication bias and informed consent of patients
in clinical trials.

The rights to the information gathered by the drug trial were legally
under the control of the contract research organisation. It is likely
that many patients enter drug trials believing that the resulting
knowledge will be available for the common good. Would the public
readily enter similar trials if they knew the intellectual property
was controlled by the sponsors and may not be available for the public
record? Commercial sensitivity, the complexity of running
multicentre trials and timing of publication demand some
flexibility, but an insistence on public record of all trial results
should be non-negotiable.

My concerns about publication bias are shared by others,2,3 and are as
follows:
- If the findings remain the property of the sponsor, then how
much evidence is never reported?
- How truthful is medical evidence that relies on publications
selected by an industry which needs to sell new drugs or variations on
existing drugs ("me-too" drugs)? "Me-too" drugs require clinical
trials showing some advantage, and these trials may be designed with
marketing strategies as the driving hypothesis. Trials that show no
difference or no effect, or even adverse effects, are less likely to be
published, while positive results are likely to be published and
promoted. Pharmaceutical companies have to make a profit or they
fail.4 There is evidence for
selective publication of drug trial information,5 and even
manipulation of information6 and opinion.7,8
- Publication bias may result in unsafe or more expensive therapies
being used. Health resources are limited and inefficient use results
in rationing elsewhere. We need all available information to be on the
public record to inform us in clinical decision-making.

Recent judgments in the Australian justice system suggest that
informed consent should involve disclosing all issues that might be
significant to the patient making the decision.9
Patients may enter drug trials as part of an ongoing doctor-patient
relationship, and this may make them feel more secure in the rigours
and supervision imposed by trial conditions.10 Patients' trust in
doctors is based on the belief that it is their health that remains the
central focus. Full disclosure of financial interests might disturb
this trust, particularly in trials conducted in private clinics with
financial payment made directly to the medical investigator. In
public institutions money gained from trials is not usually paid
directly to doctors. Generally, most of it is spent on acquiring
necessary equipment or to support further research — something
likely to be supported by the public. Disclosing trial financial
details to patients will create additional difficulties, but truth
is more important than false trust.
The Royal Australasian College of Physicians' Ethical
guidelines in the relationship between physicians and the
pharmaceutical industry11 and the National Health
and Medical Research Council's National statement on ethical
conduct in research involving humans12 state that there should be
disclosure to research participants of relevant aspects of the
budget. More recently, financial disclosure in clinical trials has
come under scrutiny in the media.13,14 If we don't ensure such
disclosure, then either the political or judicial system might
impose it on us.

We have progressed a long way in the ethical review of research.
However, ethics committees also have increasing workloads and
diminishing budgets. They are not necessarily equipped to
obsessively interrogate and supervise all submitted
projects.15,16
I propose that trial submission forms to ethics committees have two or
three further questions confirming a commitment to publish trial
results17 and to disclose financial
details. This would flag this requirement to both researchers and the
industry. Some ethics committees may already have these
requirements. The resulting transparency would increase public
trust in clinical trials, which, in turn, might make patients more
likely to volunteer, ensuring wide and valid representation of
different trial subjects.

In entering drug trials the public are risking more than the
pharmaceutical industries and the investigators. We all agree that
clinical trials are necessary and that, in the right setting, they
provide information on new and effective therapies. However, there
are other rewards that could be offered to the public.
Ready public availability of information on the risks of
pharmaceutical products would be an appropriate reward. It is
estimated that 80 000 Australians are admitted yearly to Australian
hospitals with adverse reactions to pharmaceutical
products.18 A proportion of drug trial
monies could be dedicated to the study and education of adverse drug
reactions. Another proportion of drug trial monies could be
dedicated to funding a trial register site17 to provide abstracts of
all clinical trials and their results.
Finally, we need to examine how and by whom clinical trials are
conducted as they are taken from academic medical centres into other
sites.3,19 Public institutions are
the most protective environment for the public for pharmaceutical
and biotechnology trials, provided they have transparent and
available guidelines on their interactions with the pharmaceutical
industry.20-23
