Med Journals: Where Seldom Is Heard A Discouraging Word

by GoozNews ~ 12 Dec 2008 11:35am

Fellow bloggers (Alison Bass, Howard Brody, Brandon Keim, and Andrew Hyde) have discussed a new study on publication bias published November 25 in PLoS Medicine. Publication bias is the tendency for some types of clinical trial results to be published more frequently or more quickly than others.

Recently, Erick Turner and colleagues studied publication bias in trials of antidepressants submitted to the FDA and found that 31 percent were not published, with studies having a positive result much more likely to be published. (Merrill Goozner of the Center for Science in the Public Interest -- and proprietor of this blog site -- published a similar analysis in February 2004 on the eve of the FDA advisory committee that discussed the issue of SSRI use and suicidality in children.) According to the published literature, it appeared that 94 percent of the antidepressant trials were positive, but only 51 percent of the trials submitted to the FDA were positive.

The anonymous blogger on Clinical Psychology and Psychiatry Blog discussed that study here. Publication bias can lead doctors to prescribe treatments that are less effective or less safe than indicated in the medical literature. Frequently, these treatments are also newer and more expensive than established treatments, driving up costs.

In the new study, Lisa Bero and colleagues examined all efficacy trials of New Molecular Entities (NMEs) submitted to the FDA from 2001 to 2002 (NMEs are drugs containing new active ingredients not previously approved by the FDA). They found that 22 percent of the trials were still not published five years after FDA approval of the drug. Trials with favorable outcomes were 4.7 times more likely to be published, and some publications selectively omitted outcomes that had been submitted to the FDA or added other outcomes, in each case presenting the drug in a more positive light. The statistical significance of some outcomes changed, in each case in a way that favored the drug.

In an accompanying editorial, An-Wen Chan states that "[i]t is clear that the trial literature is biased," and calls for public access to full clinical trial protocols and regulatory agency submissions.

Then there are Contract Research Organizations that are thriving presently due to pharma outsourcing their clinical trials to them, yet remain involved in the process:

The Human Injury of Lost Objectivity

If I were to rate the corruptive tactics performed by big pharmaceutical companies during my intimate experience with them , the frequent and intentional strategy of implementing fabricated and unreliable results of clinical trials performed by others possibly tops the list of corruptive tactics by the pharmaceutical industry that sponsors such trials. By this atrophy of the scientific method absent of authenticity that has been known to occur, harm and damage is possibly done to the health of the public. Most would agree that the science of research should be sound and as sterile and aseptic as possible- completely free of interference. However, it appears, money and increased profits can be a catalyst for reckless disregard for human health that is largely unregulated. This is particularly a factor on post-marketing studies of various pharmaceutical companies because others seem to be deliberately conducting nothing less than seeding trials- with about a 50 percent tax credit for these trial sponsors.
Decades ago, clinical trials were conducted at academic settings that focused on the acquisition of knowledge and the completely objective discoveries of drugs and devices to benefit mankind. Then, in 1980, the Bayh-Dole Act, Public Law 96-517,was created, which allowed for such places with their researchers to profit off of their discoveries that were performed for pharmaceutical companies and others in the past. Furthermore, such academic institutions were coerced to license patented inventions to those pharmaceutical companies that will then commercialize these discoveries paid for in large part by the taxpayers who funded this research.
This resulted in the creation of for-profit research trial sites called Contract Research Organizations that are often composed of primarily community patient care clinics absent of any research training compared with the former researcher that existed decades ago. Because of this structure, investigators of these pharmaceutical sponsored trials are likely void by sponsor design of necessary research experience or quality regarding their research purpose and ability to ensure authenticity if not ethics. This, of course, happens with intent by the sponsor who can control the trial protocol much more at these locations. These quite numerous CROS are in fact for- profit, with some CROs making billions of dollars a year, and this market continues to grow.
The trials conducted at such places again are sponsored by pharmaceutical companies that control and manipulate all aspects of the trial being conducted involving their particular drug chosen to be studied. . Etiology for their deception regarding this manipulation is because the pharmaceutical company that sponsors such a trial is basically creating a marketing tool for this drug of theirs to be studied in this manner. This coercion is done by various methods of deception in subtle and tacit methods. As a result, research in this protocol of the sponsor ensures favorable results of the sponsor’s medication after the trial is complete. Their activities are again believed to be absent of true or applied regulation to any degree, and therefore have the autonomy to create whatever they want to benefit what may be a collusive relationship between the site and the sponsor; as such sites are largely unregulated.
Guest authorship has been known to be aggressively recruited by sponsors and usually the sponsors seek investigators to be recruited for this function in addition to being the lead investigator of their fabricated clinical trial. The trial manuscript and protocol design is prepared by those employed by the drug company sponsor upon specific direction of this sponsor. The medical program coordinator of a particular sponsored trial is an actual employee of the sponsoring drug company and also acts as the publisher, manuscript version reviewe,r and trial director who works with their drug company’s hired CRO editors whose objectives are to benefit the sponsor, it has been reported. Typical and ultimate cost of the final manuscript of the trial to the sponsor created by the hired CRO exceeds 1000 dollars per page, some have said. Merck engages in this behavior, which shocked many, as they were always viewed as an ethical pharmaceutical company that always placed patients over profits. Apparently, this is no longer the case.
Further disturbing is that once the creation of the trials is completed, the research paper is often composed with specific directions by the sponsor to writers known as ghostwriters. These people are not identified and acknowledged by the sponsor, and may not be trained in clinical research overall, as they are simply freelance writers, as one does not need research training or certification in order to perform this function. Rarely do trial ghostwriters question their instructions about their assignment, which is clearly deceptive and undocumented by the sponsor. Also, these hired mystery writers are known to make about 100 grand a year. This activity removes accountability and authenticity of the possibly fabricated clinical trial even further. The corruptive act is finally completed by the sponsor hiring an author to have their name be placed on the trial, while this hired author likely had absolutely no involvement with the trial, or even reviewing the trial is not asked by the hired author.
To have the trial published, the sponsor has been known to pay an obscure journal, and the sponsor bribes the journal in a few ways, such as the sponsor purchasing from a selected journal thousands of reprints of their study from the journal, for example. Again, how often this process is performed is unknown, yet frequent enough to create hundreds of such false writers mentioned earlier and progressively growing research sites to receive the support the pharmaceutical industry. So benefits of meds studied in such a malicious way potentially can harm patients and their treatment options along with clear safety risks. The purchased reprints bought by the sponsor of the study are distributed to the sponsor’s sales force to share the content with prescribers, with the sales force completely unaware about this manipulation. As a bonus, the sponsor may agree to pay this journal to advertise their products to be placed in this journal as well.
Such misconduct discussed so far impedes research and the scientific method with frightening ethical and harmful concerns, as stated previously. If so, our health care treatment options with meds are now undetermined in large part due to such corruptive situations, as well as the absence of objectivity that has been intentionally eliminated with trials produced in this way. Trust in the scientific method in this type of activity illustrated in this article is absent and replaced with what could be harmful to others.
More now than ever, meds are removed from the market or are given black box warnings due to the damaging effects of drugs approved by the FDA.
Transparency and disclosure needs to happen with the pharmaceutical industry for reasons such as this as well as many others, in order to correct what we have historically relied upon for conclusive proof, which is the scientific method. More importantly, research should not be conducted in a way that the sponsor cannot in any way interfere in such ways described in this article, which would require independent clinical trial sites with no involvement of the drug maker. And clearly, regulation has to be enforced not selectively, but in a complete fashion regarding such matters. Public awareness would be a catalyst for this to occur, after initially experiencing a state of total disbelief that such operations actually are conducted by such people, of course. We can no longer be dependent on others for our optimal health. Knowledge is power, and is also possibly a lifesaver.

Author’s note: What has been written was based upon information and belief.

In other fields of endeavor, we have mechanisms that might be worth considering. For instance, in accepting equipment for use in workplaces, ANSI accepts standards, voting on them through a public process, often consequent on other relatively transparent consensus processes through organizations such as the for-real non-profit National Fire Protection Association. The Department of Labor certifies a very limited number of Nationally Certified Testing Laboratories (NRTLs), the best known of which is UL. Manufacturers submit a product to a NRTL for evaluation for conformance with the applicable standards, and if a product is Listed as conforming,the NRTL regularly follows up on its manufacture, in an organized if imperfect way.
In Canada, I believe, the Canadian Standards Association (which also is a U.S. NRTL, incidentally) performs all these functions.
How useful would it be to pattern a drug-testing program on this?

As Pharmalot reminded us recently, less than 20 percent of registered clinical trials of cancer drugs are eventually published in medical journals, according to a review published online by the The Oncologist medical journal. And a subsequent search of the National Library of Medicine's PubMed database showed that just 17.6 percent of the trials were eventually published in peer-reviewed medical journals.

When an oncologist recommends a treatment the reason behind the recommendation may be complex. It can be a result of the doctor's training and experience in combination with the investments made by the hospital or the doctors own research interests or financial relationships with various outside entities. Patients must be their own best advocate and get at the heart as to why a specific treatment regimen is being suggested.

An increasing number of drug studies are developed through collaborations between academic medical centers and drug companies. It is important to understand the influence that industry involvement may have on the nature and direction of cancer research. Studies backed by pharmaceutical companies were significantly more likely to report positive results.

More must be spent on analyzing drug data, and the need for larger and more detailed studies to figure out why there is an association between pharmaceutical involvement and positive results.
