As
editors of general medical journals, we recognize that the publication
of clinical research findings in respected peer-reviewed journals
is the ultimate basis for most treatment decisions. Public discourse
about this published evidence of efficacy and safety rests on the
assumption that clinical trials data have been gathered and are
presented in an objective and dispassionate manner. This discourse
is vital to the scientific practice of medicine because it shapes
treatment decisions made by physicians and drives public and private
health care policy. We are concerned that the current intellectual
environment in which some clinical research is conceived, study
subjects are recruited, and the data analyzed and reported (or not
reported) may threaten this precious objectivity.
Clinical
trials are powerful tools; like all powerful tools, they must be
used with care. They allow investigators to test biological hypotheses
in living patients, and they have the potential to change the standards
of care. The secondary economic impact of such changes can be substantial.
Well-done trials published in high-profile journals may be used
to market drugs and medical devices, potentially resulting in substantial
financial gain for the sponsor. But powerful tools must be used
carefully. Patients participate in clinical trials largely for altruistic
reasons that is, to advance the standard of care. In the light of
that truth, the use of clinical trials primarily for marketing,
in our view, makes a mockery of clinical investigation and is a
misuse of a powerful tool.
Until
recently, academic, independent clinical investigators were key
players in design, patient recruitment, and data interpretation
in clinical trials. The intellectual and working home of these investigators,
the academic medical center, has been at the hub of this enterprise,
and many institutions have developed complex infrastructures devoted
to the design and conduct of clinical trials.1,
2 The academic enterprise has been a critical
part of the process that led to the introduction of many new treatments
into medical practice and contributed to the quality, intellectual
rigor, and impact of such clinical trials. But, as economic pressures
mount, this may be a thing of the past.
Many
clinical trials are performed to facilitate regulatory approval
of a device or drug rather than to test a specific novel scientific
hypothesis. As trials have become more sophisticated and the margin
of untreated disease harder to reach, there has been a great increase
in the size of the trials and consequently in the costs of developing
new drugs. It is estimated that the average cost of bringing a new
drug to market in the United States is about $500 million.3
The pharmaceutical industry has recognized the need to control costs
and has discovered that private nonacademic research groups-ie,
contract research organizations (CROs)-can
do the job for less money and with fewer hassles than academic investigators.
Over the past few years CROs have received the lion's share of clinical
trial revenues. For example, in 2000 in the United States, CROs
received 60% of the research grants from pharmaceutical companies,
as compared with only 40% for academic trialists.1
As
CROs and academic medical centers compete head to head for the opportunity
to enroll patients in clinical trials, corporate sponsors have been
able to dictate the terms of participation in the trial, terms that
are not always in the best interests of academic investigators,
the study participants, or the advancement of science generally.4
Investigators may have little or no input into trial design, no
access to the raw data, and limited participation in data interpretation.
These terms are draconian for self-respecting scientists, but many
have accepted them because they know that if they do not, the sponsor
will find someone else who will. And, unfortunately, even when an
investigator has had substantial input into trial design and data
interpretation, the results of the finished trial may be buried
rather than published if they are unfavorable to the sponsor's product.
Such issues are not theoretical. There have been a number of recent
public examples of such problems,5,
6 and we suspect that many more go unreported.
As
editors, we strongly oppose contractual agreements that deny investigators
the right to examine the data independently or to submit a manuscript
for publication without first obtaining the consent of the sponsor.
Such arrangements not only erode the fabric of intellectual inquiry
that has fostered so much high-quality clinical research, but also
make medical journals party to potential misrepresentation, since
the published manuscript may not reveal the extent to which the
authors were powerless to control the conduct of a study that bears
their names. Because of our concern, we have recently revised and
strengthened the section on publication ethics in the "Uniform Requirements
for Manuscripts Submitted to Biomedical Journals: Writing and Editing
for Biomedical Publication," a document developed by the International
Committee of Medical Journal Editors (ICMJE) and widely used by
individual journals as the basis for editorial policy. The revised
section follows this editorial. (The entire "Uniform Requirements"
document is currently undergoing revision; the revised version should
be available at the beginning of 2002.) As part of the reporting
requirements, we will routinely require authors to disclose details
of their own and the sponsor's role in the study. Many of us will
ask the responsible author to sign a statement indicating that he
or she accepts full responsibility for the conduct of the trial,
had access to the data, and controlled the decision to publish.
We
believe that a sponsor should have the right to review a manuscript
for a defined period (eg, 30-60 days) before publication to allow
for the filing of additional patent protection, if required. When
the sponsor employs some of the authors, these authors' contributions
and perspective should be reflected in the final paper as are those
of the other authors, but the sponsor must impose no impediment,
direct or indirect, on the publication of the study's full results,
including data perceived to be detrimental to the product. Although
we most commonly associate this behavior with pharmaceutical sponsors,
research sponsored by governmental or other agencies may also fall
victim to this form of censorship, especially if the results of
such studies appear to contradict current policy.
Authorship
means both accountability and independence. A submitted manuscript
is the intellectual property of its authors, not the study sponsor.
We will not review or publish articles based on studies that are
conducted under conditions that allow the sponsor to have sole control
of the data or to withhold publication. We encourage investigators
to use the revised ICMJE requirements on publication ethics to guide
the negotiation of research contracts. Those contracts should give
the researchers a substantial say in trial design, access to the
raw data, responsibility for data analysis and interpretation, and
the right to publish-the
hallmarks of scholarly independence and, ultimately, academic freedom.
By enforcing adherence to these revised requirements, we can as
editors assure our readers that the authors of an article have had
a meaningful and truly independent role in the study that bears
their names. The authors can then stand behind the published results,
and so can we.

Conflict
of Interest
Public
trust in the peer review process and the credibility of published
articles depend in part on how well conflict of interest is handled
during writing, peer review, and editorial decision making. Conflict
of interest exists when an author (or the author's institution),
reviewer, or editor has financial or personal relationships with
other persons or organizations that inappropriately influence (bias)
his or her actions. The potential of such relationships to create
bias varies from negligible to extremely great; the existence of
such relationships does not necessarily represent true conflict
of interest, therefore. (Relationships that do not bias judgment
are sometimes known as dual commitments, competing interests, or
competing loyalties). The potential for conflict of interest can
exist whether or not an individual believes that the relationship
affects his or her scientific judgment. Financial relationships
(such as employment, consultancies, stock ownership, honoraria,
paid expert testimony, patents) are the most easily identifiable
conflicts of interest and the most likely to undermine the credibility
of the journal, the authors, and of science itself. Conflicts can
occur for other reasons, however, such as personal and family relationships,
academic competition, and intellectual passion.
All
participants in the peer review and publication process must disclose
all relationships that could be viewed as presenting a potential
conflict of interest. Disclosure of these relationships is particularly
important in connection with editorials and review articles, because
bias can be more difficult to detect in those publications than
in reports of original research. Editors may use information disclosed
in conflict of interest and financial interest statements as a basis
for editorial decisions. Editors should publish this information
if they believe it will be important to readers in judging the manuscript.
Potential
Conflicts of Interest Related to Individual Authors' Commitments
When
authors submit a manuscript, whether an article or a letter, they
are responsible for disclosing all financial and personal relationships
between themselves and others that might bias their work. To prevent
ambiguity, authors must state explicitly whether potential conflicts
do or do not exist. Authors should do so with the manuscript on
a conflict of interest notification page, providing additional detail,
if necessary, in the accompanying cover letter.
Investigators
should disclose potential conflicts to study participants, and should
state in the manuscript whether they have done so.
Editors
also need to decide when to publish information disclosed by authors
about potential conflicts. If doubt exists, it is best to err on
the side of publication.
Potential
Conflicts of Interest Related to Project Support
Increasingly,
biomedical studies receive funding from commercial firms, private
foundations, and government. The conditions of this funding have
the potential to bias and otherwise discredit the research.
Scientists
have an ethical obligation to submit creditable research results
for publication. As the persons directly responsible for their work,
researchers therefore should not enter into agreements that interfere
with their access to the data or their ability to analyze the data
independently, to prepare manuscripts, and to publish them. Authors
should describe the role of the study sponsor(s), if any, in study
design; in the collection, analysis, and interpretation of data;
in the writing of the report; and in the decision to submit the
report for publication. If the supporting source had no such involvement,
the authors should so state. Biases potentially introduced when
sponsors are directly involved in research are analogous to methodological
biases of other sorts; some journals therefore choose to include
information about the sponsor's involvement in the methods section
of the published paper.
If
a study is funded by an agency with a proprietary or financial interest
in the outcome, editors may ask authors to sign a statement such
as, "I had full access to all of the data in this study and I take
complete responsibility for the integrity of the data and the accuracy
of the data analysis." Editors should be encouraged to review copies
of the protocol and/or contracts associated with project-specific
studies before accepting such studies for publication. Editors may
choose not to consider an article if a sponsor has asserted control
over the authors' right to publish.
Conflicts
of Interest Related to Commitments of Editors, Journal Staff, or Reviewers
Editors
should avoid selecting external peer reviewers with obvious potential
conflicts of interest, for example, those who work in the same department
or institution as any of the authors. Authors often provide editors
with the names of persons they feel should not be asked to review
a manuscript because of potential conflicts of interest, usually
professional. When possible, authors should be asked to explain
or justify their concerns; that information is important to editors
in deciding whether to honor such requests.
Reviewers
must disclose to editors any conflicts of interest that could bias
their opinions of the manuscript, and they should disqualify themselves
from reviewing specific manuscripts if they believe such disqualification
would be appropriate. As in the case of authors, silence on the
part of reviewers concerning potential conflicts may mean either
that such conflicts exist that they have failed to disclose or that
conflicts do not exist. Reviewers must therefore also be asked to
state explicitly whether conflicts do or do not exist. Reviewers
must not use knowledge of the work, before its publication, to further
their own interests.
Editors
who make final decisions about manuscripts must have no personal,
professional, or financial involvement in any of the issues they
might judge. Other members of the editorial staff, if they participate
in editorial decisions, must provide editors with a current description
of their financial interests (as they might relate to editorial
judgments) and disqualify themselves from any decisions where they
have a conflict of interest. Editorial staff must not use the information
gained through working with manuscripts for private gain.
Editors
should avoid submitting to their own journal reports of original
research to which they have contributed as authors. If they do so,
they should recuse themselves from the editorial process and delegate
editorial decisions on those manuscripts to other members of the
editorial staff.
Editors
should publish regular disclosure statements about potential conflicts
of interests related to the commitments of journal staff.
