There They Go Again, Again... - Johnson and Johnson Loses Two Civil Cases, Makes $2.5 Billion Settlement Based on Claims it Withheld Safety Data on its Products

There has been some talk by US government officials that any day now they will actually get tough on corporate executives whose organizations are involved in multiply unethical actions (perhaps using the legally valid, but massively neglected responsible corporate officer doctrine, look here).  However, the march of legal settlements by such corporations continue without any hints of negative consequences for the people who might have actually been involved in unethical activity. 

So, we note another week, another multi-billion dollar settlement and another loss of a civil lawsuit by huge drug, device and biotechnology company Johnson and Johnson

The Articular Surface Replacement Metal-on-Metal Hip Prosthesis Settlement

After various rumors, the report of the settlement appeared in a New York Times article on November 19, 2013.  The basics were,

Johnson & Johnson and lawyers for patients injured by a flawed hip implant announced a multibillion-dollar deal on Tuesday to settle thousands of lawsuits, but it was not clear whether the deal would satisfy enough claimants.

Under the agreement, the medical products giant would pay nearly $2.5 billion in compensation to an estimated 8,000 patients who have been forced to have the all-metal artificial hip removed and replaced with another device. 

Separately, the company has agreed to pay all medical costs related to such procedures, expenses that could raise the deal’s cost to Johnson & Johnson to $3 billion, people familiar with the proposal said.

Under the plan, the typical patient payment for pain and suffering caused by the device would be about $250,000 before legal fees. Based on standard agreements, plaintiffs’ lawyers would receive about one-third of the overall payout, or more than $800 million, with those who negotiated the plan emerging as big winners.

The proposed settlement, which was submitted on Tuesday to a federal judge in Toledo, Ohio, must receive the support of 94 percent of eligible claimants to go forward.

An earlier NY Times article on a rumored version of the settlement emphasized that relevant litigation had featured strong allegations that Johnson  and Johnson's DePuy subsidiary hid what it knew about the faults of the device,


The A.S.R. hip was sold by DePuy until mid-2010, when the company recalled it amid sharply rising early failure rates. The device, which had a metal ball and a metal cup, sheds metallic debris as it wears, generating particles that have damaged tissue in some patients or caused crippling injuries. 

DePuy officials have long insisted that they acted appropriately in recalling the device when they did. However, internal company documents disclosed during the trial of a patient lawsuit this year showed that DePuy officials were long aware that the hip had a flawed design and was failing prematurely at a high rate.

Many artificial hips last 15 years or more before they wear out and need to be replaced. But by 2008, data from orthopedic databases outside the United States also showed that the A.S.R. was failing at high rates in patients after just a few years.

Internal DePuy projections estimate that it will fail in 40 percent of those patients in five years, a rate eight times higher than for many other hip devices. 

A later NY Times article about plaintiffs' sometimes negative reactions to the settlement added,

 The DePuy Orthopaedics division of Johnson & Johnson estimated in an internal document in 2011 that the device would fail within five years in 40 percent of patients. Traditional artificial hips, which are made of metal and plastic, typically last 15 years or more before replacement. 

 DePuy officials have insisted that they acted properly in handling the device, including waiting until 2010 to recall it. However, internal company documents show that company officials were warned years before by their own consultants that the device was so problematic they would not use it in their patients. 

In January, 2013, the NY Times had reported in more detail about how DePuy executives concealed evidence about safety issues with the hips,

. Johnson and Johnson executives knew years before they recalled a troubled artificial hip in 2010 that it had a critical design flaw, but the company concealed that information from physicians and patients, according to internal documents disclosed on Friday during a trial related to the device’s failure.

The company had received complaints from doctors about the device, the Articular Surface Replacement, or A.S.R., even as it started marketing a version of it in the United States in 2005. The A.S.R.’s flaw caused it to shed large quantities of metallic debris after implantation, and the model failed an internal test in 2007 in which engineers compared its performance to that of another of the company’s hip implants, the documents show.

Still, executives in Johnson & Johnson’s DePuy Orthopaedics unit kept selling the A.S.R. even as it was being abandoned by surgeons who worked as consultants to the company. DePuy executives discussed ways of fixing the defect, the records suggest, but they apparently never did so.
Plaintiffs’ lawyers introduced the documents on Friday in Los Angeles Superior Court during opening arguments in the first A.S.R.-related lawsuit to go to trial.
In particular, 
In 2007, DePuy engineers tested the A.S.R.’s rate of wear to see if it matched the wear rate of another all-metal hip implant made by the company. It did not.

'The current results for A.S.R. do not meet the set acceptance criteria for this test,' that report stated.

The same year, company officials began discussing ways to fix the problem, like redesigning the cup to eliminate the groove. But at the same time, it was actively marketing the A.S.R. to surgeons in the United States, who were implanting it into tens of thousands of patients.

'We will ultimately need a cup redesign, but the short-term action is manage perceptions,' one top DePuy sales official told a colleague in a 2008 e-mail. A DePuy executive, Andrew Ekdahl, who is now the unit’s president, was also told by a company consultant that the A.S.R. was flawed, according to another document. 

In mid-2008, DePuy apparently abandoned the redesign project, an internal document indicates. A company spokeswoman, Mindy Tinsley, declined to comment on the document. 

In the fall of 2009, the Food and Drug Administration rejected DePuy’s application to sell the resurfacing version of the A.S.R. in the United States, saying it was concerned about, among other things, “high concentration of metal ions” in the blood of patients who received it. 

DePuy executives soon started making financial estimates of when the company should stop selling the A.S.R., based on the time it would take to convert surgeons to another company implant, a document shows.

So the evidence introduced in litigation suggested that top DePuy executives knew the design was faulty, but chose to not disclose the evidence of this, and not to withdraw the product, but rather to "manage perceptions." 

As is typical of most settlements made by big health care corporations in the last 10 years, no one at DePuy or its Johnson and Johnson parent who might have authorized, directed, or implemented the continued sales of the device despite warnings that it might be unsafe would have to suffer any negative consequences.  In particular, apparently Mr Ekdahl will not suffer any such consequences (and was not obviously named in the few news reports of the settlement.)   Mr Ekdahl, now Worldwide President, DePuy Synthes Joint Reconstruction, was quoted in the official Johnson and Johnson news release about the settlement.

The Topamax Verdicts

This case, which was much smaller in terms of the monetary amounts involved, got much less coverage, but Bloomberg did report on November 18, 2013,

Johnson & Johnson's  Janssen Pharmeceuticals unit was ordered by a Philadelphia jury to pay $11 million in a case claiming its anti-seizure drug Topamax caused birth defects, the second such loss in less than a month.

Again, the case involved claims that the company withheld information about the safety of its product,

Janssen failed to adequately warn doctors for Haley Powell, a stay-at-home mother, of the risks of Topamax before she gave birth to a son with a cleft lip, jurors in state court in Philadelphia found today.

'Janssen has long known that this drug causes debilitating birth defects and yet intentionally kept this information from physicians and patients,' Shelley Hutson, an attorney for Powell, said after the verdict was read.

Furthermore,

 Janssen knew as early as 1997 that animal studies showed an increased risk for birth defects, especially oral clefts, Hutson said during closing arguments on Nov. 15.


Hutson accused Janssen of operating in a culture of secrecy and of intentionally concealing safety reports in 2003 and 2005.She rejected arguments by the company that it presented the information on poster boards, in abstracts and at medical conferences. Those actions “do not keep patients safe,” Hutson said.

'As early as 1997 in admission after admission, this company knew and they didn’t tell the doctors,' Hutson said.

A report in Law360 emphasized,

 Plaintiffs in the Pennsylvania suits alleged the company didn't fully, truthfully or accurately disclose Topamax data to the FDA, to them and to their doctors. As a result, Janssen intentionally and fraudulently misled the medical community, the public and herself about the risks to a fetus associated with the use of Topamax during pregnancy, plaintiffs claimed.

 Summary

There they go again....  So Johnson and Johnson has announced two multi-billion dollar settlements in one month (November, 2013, look here for the first).  It also announced a smaller settlement involving the marketing of Topamax, which is now in addition to a 2010 guilty plea for misbranding Topamax in 2010 (look here).  Note that all the November, 2013 legal actions involved allegations, often backed by seemingly convincing evidence produced in litigation (as noted above), of deceptive, unethical practices.  Both cases above included allegations that the company sold products without fully disclosing those products' harms to patients.  Furthermore, all the month's legal actions are now added to a long list of Johnson and Johnson's legal woes, often involving allegations and evidence of other unethical actions, sometimes involving guilty pleas to charges of such actions (see compilation of the record through July, 2013 here.)  (By the way, Synthes, which is now another Johnson and Johnson subsidiary, and is not run by the same individual on whose watch the ASR case occurred, has had its own legal and ethical woes, look here.) 

Yet despite this lengthy and sorry record, no individual manager or executive at Johnson and Johnson, including its many and confusing subsidiaries, seems to have suffered any negative consequences for authorizing, directing, or implementing any unethical activities, whether they risked harming patients, or whether they resulted in a guilty plea by a corporate entity.  Instead, as we have discussed most recently here, the top executives of the company have grown very rich. 

So since the US government seems to continue to recycle its policy of allowing corporate managers and executives impunity regardless of how repetitively harmful their actions might be to patients' and the public's health, I will recycle my comments from earlier in November, 2013,....

The latest settlement in the parade is another marker of the sort of conduct that big health care organizations have exhibited to increase revenue, and to use that revenue as a rationale for making their top insiders very rich.  The particular conduct alleged here could have put patients at risk, partly by deceiving health care professionals.  Yet in their wisdom, top US law enforcement saw fit not to try to hold any individuals accountable for this conduct, and allowed the company to deny any misconduct other than a single misdemeanor by a subsidiary.  This occurred despite the company's history of multiple legal settlements and findings of guilt in various courtrooms.

Yet none of these actions has resulted in any negative consequences for any individual within the company.  No one who authorized, directed, or implemented bad behavior will pay any penalty, even were the bad behavior to have lead to significant personal enrichment.

As we have said ad infinitum, and on the occasion of a previous Johnson and Johnson settlement, many of largest and once proud health care organizations now have recent records of repeated, egregious ethical lapses. Not only have their leaders have nearly all avoided penalties, but they have become extremely rich while their companies have so misbehaved.

These leaders seem to have become like nobility, able to extract money from lesser folk, while remaining entirely unaccountable for bad results of their reigns. We can see from this case that health care organizations' leadership's nobility overlaps with the supposed "royalty" of the leaders of big financial firms, none of whom have gone to jail after the global financial collapse, great recession, and ongoing international financial disaster (look here). The current fashion of punishing behavior within health care organization with fines and agreements to behave better in the future appears to be more law enforcement theatre than serious deterrent.  As Massachusetts Governor Deval Patrick exhorted his fellow Democrats, I exhort state, federal (and international, for that  matter) law enforcement to "grow a backbone" and go after the people who were responsible for and most profited from the ongoing ethical debacle in health care.

As we have said before, true health care reform would make leaders of health care organization accountable for their organizations' bad behavior.

Why Trust Drug Company Executives After One Admits Commercially Sponsored Clinical Research Is All About "Competitive Advantage?"

Mickey, the semi-anonymous blogger on 1BoringOldMan, wrote a righteously angry post in support of transparent clinical research.  As we have noted frequently, clinical trials done on human subjects are often manipulated to increase the likelihood of results favorable to commercial sponsors, or suppressed when even such manipulation does not produce the desired results.

Note that such suppression and manipulation degrade the scientific value of the studies, impede the evidence-based medicine process to rationally apply clinical research evidence to improve the health of patients and the public, and violate the trust of research subjects who volunteer to participate based on the assumption that clinical research is meant to improve patient care and public health, and contribute to science, not just secure commercial advantage.  

A European initiative to combat suppression of clinical research has been opposed by a lawsuit from US pharmaceutical manufacturers AbbeVie, spun off from Abbott Laboratories, and Intermune.  The European Medicines Agency had been willing to to make public unpublished patient level data from commercially sponsored clinical trials.  The lawsuit has shut down the process, and is meant to shut it down permanently, claiming that the clinical data, obtained from volunteer research subjects, includes "trade secrets."

As summarized by Mickey, their motivation seems to be to conceal how pharmaceutical manufacturers and other commercial sponsors of human research use this research for promotional, rather than scientific purposes.

An AbbeVie lawyer asserted that some adverse effects data should be kept confidential, and that "internal tactical decisions on how we are going to run a study, engage with regulators, and confront and solve problems and challenges we have uncovered during clinical trials" should also be kept secret because revealing them could "give other companies a tremendous competitive advantage," never mind whether keeping secrets could undermine science, decrease the study's usefulness to aid clinical and policy decision making, and break the implicit contract between researchers and study subjects.

It is becoming more obvious that many drug company executives, and other leaders of large health organizations, may care more about "competitive advantage" than patients, science or the public good, as Mickey points out.  So much for that advertising puffery  about drug development to improve patient health.  Thus it may be ridiculous to think that these executives they will negotiate to improve transparency of clinical research in good faith when doing so could decrease such advantage, again no matter what the effect on patients, public health, or science.

On this case there is an opportunity to speak out, Dr David Healy has a petition up on Change.org to oppose the AbbeVie and Intermune lawsuit which might get some notice if there are enough signatures.

Pharmaceutical Industry "'Mobilised' an Army of Patient Groups to Lobby Against" Improving Clinical Research Integrity

I had guessed that this sort of thing was going on all the time, but being kept very well hidden.  Now we have some more evidence.

An article in yesterdays Guardian showed how the pharmaceutical industry is using pet patient advocacy groups in a public relations campaign to defeat calls for for measures against suppression and manipulation of clinical research. In summary,

The pharmaceutical industry has 'mobilised' an army of patient groups to lobby against plans to force companies to publish secret documents on drugs trials.

More specifically,


The strategy was drawn up by two large trade groups, the Pharmaceutical Research and Manufacturers of America (PhRMA) and the European Federation of Pharmaceutical Industries and Associations (EFPIA), and outlined in a memo to senior industry figures this month, according to an email seen by the Guardian.  The memo, from Richard Bergström, director general of EFPIA, went to directors and legal counsel at Roche, Merck, Pfizer, GSK, AstraZeneca, Eli Lilly, Novartis and many smaller companies. It was leaked by a drugs company employee.

The email describes a four-pronged campaign that starts with 'mobilising patient groups to express concern about the risk to public health by non-scientific re-use of data'. Translated, that means patient groups go into bat for the industry by raising fears that if full results from drug trials are published, the information might be misinterpreted and cause a health scare.

The lobbying is targeted at Europe where the European Medicines Agency (EMA) wants to publish all of the clinical study reports that companies have filed, and where negotiations around the clinical trials directive could force drug companies to publish all clinical trial results in a public database.

The argument for continuing to allow clinical trials to be suppressed was to be,

The patient groups focus on the concern that if companies release all of their clinical trials data, the information might be misconstrued, or intentionally cherry-picked, and spark damaging health scares around certain drugs or vaccines.

The Guardian story did not disclose which patient groups were cooperating with this effort.

By the way, the other parts of this strategy involved using scientific associations and academics to push the pharmaceutical companies' agenda,

 Two other strands of the campaign include discussions with scientific associations about the risks of data sharing, and work with other businesses that are concerned about the release of trade secrets and confidential data. The final strand calls, in the long term, for a network of academics across Europe that can be called on to correct false interpretations of the data. 
Several of the large multinational drug companies contacted by the Guardian issued the usual non-denial denials

In response to queries from the Guardian, GSK said: 'This is not something we are doing. One of the reasons we're involved in this is we want more companies to move towards greater transparency. I don't think it's for us to be mobilising patient groups to campaign on a negative level.'

A Roche spokesperson said the company consulted patient groups to understand their concerns about clinical trials, but 'to our knowledge Roche has not been involved in any EFPIA's potential activity in mobilising patient groups to express concern about the risk to public health by non-scientific re-use of data'.

A Lilly spokesman said: 'Lilly is committed to working with Europe-based patient advocacy organisations for the benefit of patients in a way that is true to the EFPIA code of practice and Lilly's integrity in business policy.'


Summary

We have long discussed and decried how vested interests, chiefly health care corporations with services and products to sell, have manipulated clinical research to make their wares look better, and suppressed research whose results, even if manipulated, could not be made sufficiently favorable. This has resulted in making drugs and devices look more efficacious and/or less hazardous than they really are.  See this post for our latest discussion, and information on the latest effort to counter suppression and manipulation of clinical research.

It is not surprising that pharmaceutical companies do not want to have to publish every clinical trial they sponsor, or expose their manipulations of these trials.  Instead, the Guardian article suggests that companies and their trade associations, including the US based pharmaceutical trade association, and several large US companies, and well as large companies based elsewhere, are using a third-party public relations strategy.  Wendell Potter's muckraking book on the US commercial health care insurance industry, Deadly Spin, revealed how similar strategies were used by US based health insurance companies to defeat the Clinton administration's attempt at health care reform, and other measures targeted to make the US commercial health care insurance system more equitable and ethical  (see post here).  Third party strategies are fundamentally deceptive.   

The current alleged use of the third party strategies by pharmaceutical companies to support ongoing suppression and manipulation of clinical research is more than just deceptive.  It is corrupt.

Patient advocacy groups are usually believed to represent patients' interests.  For such groups to support a public relations campaign that could allow ongoing harm of patients (by suppressing and manipulating evidence to prevent it from being used to forestall excess use of ineffective, dangerous drugs) is abuse of their entrusted power.  To do it for money, money used to support these groups, or help underwrite generous compensation for their executives, fits the definition of corruption used by Transparency International - abuse of entrusted power for private gain.

Note that the Guardian provided this viewpoint,

Tim Reed, of Health Action International, a group that has previously exposed the pharmaceutical industry's financial links with patient groups, said: 'It's incredibly ironic that this is a transparency initiative and we've now got clear indications that the pharmaceutical industry is ready to use patient organisations to fight their corner.

'It underlines the fact that patient groups who are in the pay of the pharmaceutical industry will go into battle for them. There's a hidden agenda here. The patient groups will say they think it's a great idea to keep clinical trials data secret. Why would they do that? They would do that because they are fronts for the pharmaceutical industry.

'Patient groups get traction because they are assumed to represent the voice of the suffering. But industry uses them to say we're not going to get innovative medicines if the industry is deterred from investing by having to be transparent about their clinical trials,' he added.

We have previously noted isolated examples of evidence that particular US based patient advocacy groups were being supported by commercial firms presumably to aid their marketing.  We have also found examples of conflicts of interest affecting medical societies, and many affecting non-profit hospitals and academic medical institutions, and their staff and faculty.  I begin to wonder if most health care non-profit organizations in the US, and now it appears maybe in UK and in Europe, have been paid off to support marketing and/or public relations interests of health care corporations.

This latest example suggests that health care worldwide has become deeply corrupt, even more corrupt than Transparency International's Global Report on health care corruption in 2006, or the those responding to Transparency International's global corruption survey in 2013, could envision.

I only hope that the pile up of new examples - each seemingly worse than the one before - of health care corruption, will be sufficient to overcome the anechoic effect, and create enough global outrage to give us a chance to clean up our corrupt health care before it destroys our health.

A Call to Restore the Integrity of Clinical Research - but Will Anyone Heed it?

Concerns about suppression and manipulation of clinical research to serve vested interests have finally gotten a little more mainstream.

Background: Suppression and Manipulation of Clinical Research

For a long time, we have decried and discussed examples of manipulation of clinical research done to increase the likelihood that its results would please vested interests, often drug, device or other corporations that sponsored the research and often exerted considerable control over its design, implementation, analysis, and dissemination.  We have also decried and discussed examples of suppression of research whose results offended such vested interest, sometimes done when manipulation did not succeed in producing such pleasing results.


I wrote about suppression of research in my 2003 paper on health care dysfunction,(1)

The integrity of medical research has been violated by the deliberate suppression of its results.

That assertion was based on several important, although understandably largely anechoic cases.

I first wrote about systematic attempts to manipulate clinical research in 2005, based on Richard Smith's PLoS Medicine commentary which listed specific tactics that vested interests could use to make it more likely that research studies would provide them with favorable results.

Although striking cases of manipulation and suppression appeared more frequently starting in the 1990s, in the last few years it has become more apparent that these are widespread problems.

A Call to Restore Integrity

This week, the British Medical Journal published a special article calling for restoration of suppressed or manipulated clinical trials(2), accompanied by an editorial entitled, "restoring the integrity of the clinical trial evidence base."(3)

The article used slightly different terminology than we do, replacing suppression with invisibility, and manipulation with distortion, thus,

Two basic problems of representation are driving growing concerns about relying on published research to reflect the truth. The first is no representation (invisibility), which occurs when a trial remains unpublished years after completion. The second is distorted representation (distortion), which occurs when publications in medical journals present a biased or misleading description of the design, conduct, or results of a trial.

The article boldly asserted

Both go against the fundamental scientific and ethical responsibility that all research on humans be used to advance knowledge and are symptomatic of a general culture of data secrecy. The end result is that the healthcare, biomedical research, and policy communities may, despite best intentions and best practices, end up drawing scientifically invalid conclusions based on only those parts of the evidence base they can see.

The editorial went further, asserting that

This crisis of hidden or misreported information from clinical trials—and the resulting distortion of the clinical evidence base—is widely recognized and commonly decried. It is one of the leading scientific problems of our time, but few solutions have been put forward.

Furthermore, it concluded with a warning about the immorality of continuing on the current course,

The results of clinical trials are a public, not a private, good. The public interest requires that we have a complete view of previously conducted trials and a mechanism to correct the record for inaccurately or unreported trials. If we do not act on this opportunity to refurbish and restore abandoned trials, the medical research community will be failing its moral pact with research participants, patients, and the public. It is time to move from whether to how, and from words to action.

Thus the notion that suppression and manipulation of clinical research is a systemic, severe problem that confounds health professionals and hurts patients is no longer a concern of only a few fringe dissidents, but a matter for discussion in the foremost mainstream medical journals.

Will Anyone Heed the Call?

Furthermore, this dire problem formulation suggests the need for a strong solution, as proposed by the article, and seconded by the editorial.  Using the term "abandoned trials" for " unpublished trials for which sponsors are no longer actively working to publish or published trials that are documented as misreported but for which authors do not correct the record using established means such as a correction or retraction (which is an abandonment of responsibility)," Doshi and colleagues wrote,

We call on institutions that funded and investigators who conducted abandoned trials to publish (in the case of unpublished trials) or formally correct or republish (in the case of misreported trials) their studies within the next year.

Starting in 2005, we have repeatedly called for protection of " researchers' rights to speak truth to power," but then noted that "right now, it is more often power that speaks to truth."  The question is whether without some bigger allies, individual clinical researchers will stand up on their own to restore the integrity of clinical research.

The big reason to worry is that most of these researchers work within a context which strongly favors vested interests, rather than scientific truth, or the rights of research subjects.  The researchers who would be most likely to be able to heed the call by Doshi et al are those within academic medicine. Yet clinical research in the academic medical world now functions within a strong and deep web of individual and institutional conflicts of interests, subjects that we also have written about incessantly.

There is evidence suggesting that the majority of medical faculty,(4) and the majority of their academic departmental leaders(5) have important financial ties to the health care corporations most likely to have reason to want to suppress or manipulate research.  Furthermore, most academic medical institutions have stated their interest in increasing "collaboration" with industry, usually giving the rationale that this will lead to "innovations" that will bring better tests or treatment to patients. (See posts herehere and here for some examples.)  Such collaboration also tends to bring a lot of money to institutional budgets.  Further collaboration with industry is likely favored by academic leaders' own financial ties to the same sorts of corporations discussed above.  Thus it should be no surprise that a study by Mello et al in 2005 suggested that most of the managers of academic medical institutions who control research contracts are willing to give significant control of of research design, implementation, analysis, and dissemination to the sponsors, not the researchers.  (See this post.) (6)


Thus, a researcher who volunteers to restore suppressed or manipulated clinical studies might become suddenly very unpopular with his or her colleagues or supervisors, and perhaps with people who are already paying him or her.

So as long as health care professionals, policy makers, and the public at large are willing to go along with the notion that academic medical institutions' "collaboration" with "industry" is absolutely necessary to foster "innovation" and hence medical progress, it is very unlikely that academic medical researchers will be willing to help restore the integrity of clinical research.  In fact, while we continue on our present course, the integrity of clinical research will probably get even worse.
 
Since questioning the integrity of contemporary clinical research might make those with vested interests who have been willing to suppress or manipulate research very uncomfortable, perhaps it should be no surprise that the paired articles in the British Medical Journal have been relatively anechoic.  For example, while one might think the publication of these simultaneous articles might get at least a little coverage in the "main-stream media," I can find not a single mention of them there.  (So far, only the Chronicle of Higher Education, MedScape the Science Insider blog and The Scientist blog have provided news coverage.)


So I hope the brave people who wrote the article and editorial are also willing to join us in decrying the web of individual and institutional conflicts of interest that have entangled health care professionals and academic medicine.  Individuals and institutions who make medical or health care decisions, or who are involved in medical and health care education and research should reveal all their conflicts of interest, at least in the interests of honesty.  Furthermore, in the interest of patients' and the public's health, clinical research meant to assess medical tests, treatments, and programs should be done completely independently from the corporations that sell them.

A Condemnation of Suppression of Medical Research... by Ben Goldacre in the New York Times

Amazingly, this topic now seems to be in the mainstream.

The Goldacre Version in the New York Times in 2013

In his op-ed, Ben Goldacre introduced it thus:

the entire evidence base for medicine has been undermined by a casual lack of transparency. Sometimes this is through a failure to report concerns raised by doctors and internal analyses, as was the case with Johnson & Johnson. More commonly, it involves the suppression of clinical trial results, especially when they show a drug is no good.

He noted that this problems was supposed to be fixed by the registration of clinical trials, and by changes in editorial policies at medical journals:

many in the industry now claim it has been fixed. But every intervention has been full of loopholes, none has been competently implemented and, lastly, with no routine public audit, flaws have taken years to emerge.

 The Food and Drug Administration Amendments Act of 2007 is the most widely cited fix. It required that new clinical trials conducted in the United States post summaries of their results at clinicaltrials.gov within a year of completion, or face a fine of $10,000 a day.  But in 2012, the British Medical Journal published the first open audit of the process, which found that four out of five trials covered by the legislation had ignored the reporting requirements. Amazingly, no fine has yet been levied. 

An earlier fake fix dates from 2005, when the International Committee of Medical Journal Editors made an announcement: their members would never again publish any clinical trial unless its existence had been declared on a publicly accessible registry before the trial began. The reasoning was simple: if everyone registered their trials at the beginning, we could easily spot which results were withheld; and since everyone wants to publish in prominent academic journals, these editors had the perfect carrot. Once again, everyone assumed the problem had been fixed. 

But four years later we discovered, in a paper from The Journal of the American Medical Association, that the editors had broken their promise: more than half of all trials published in leading journals still weren’t properly registered, and a quarter weren’t registered at all. 

Goldacre's conclusions were:

Withholding data not only misleads doctors and patients; it’s an insult to the patients who have participated in clinical trials, believing that they were helping to improve medical knowledge. 

Medicine routinely overcomes enormous technical challenges, and there is nothing complicated about the changes needed to prevent Johnson & Johnson, or Roche — or anybody — from withholding information.

Hear, hear!

Our Version, Starting in 2003

Note that 10 years ago, in 2003, in my article on American health care dysfunction that could have been only published in Europe, (Poses RM. A cautionary tale: the dysfunction of American health care. Eur J Intern Med 2003 Mar;14(2):123-130.  Link here)  I noted that an important cause of this dysfunction is that:

the scientific basis of medicine is increasingly under attack.

The integrity of medical research has been violated by the deliberate suppression of its results.

At that time, I suggested one solution would be:

Medical schools and universities must re-affirm their support of scholarly work in the spirit of free enquiry,...

Furthermore, in one of our first posts on Health Care Renewal in December, 2004, in the context of the discovery of internal company documents (in this case, from Eli Lilly) that showed that information about the adverse effects of a drug (in this case, increased aggression associated with fluoxetine, that is, Prozac), we wrote,

The increasingly complex story of suppression of SSRI research seems to be part of a growing epidemic of suppression of medical research.
Let's say it again. Withholding data from clinical research is unethical because:
1. it breaks the promise to research subjects that their voluntary participation has scientific or social value, but undisseminated research has no value; (See Emanuel EJ et al. What makes clinical research ethical? JAMA 2000; 283: 2701-2711.)
2. it impedes scientific progress;
3. it prevents patients from receiving the best possible medical care.
But until this unethical behavior starts having negative consequences for its perpetrators, the epidemic of research suppression is likely to continue. 

Note the similarity to what Goldacre published in the Times yesterday.  You heard it here first.

Summary
To date we have published 102 posts with the label "suppression of medical research."  Obviously, Ben Goldacre's NY Times op-ed shows that suppression of research still rarely leads to negative consequences for its perpetrators.  Obviously, by making drugs, devices, and other health care interventions appear safer and more effective than they really are, suppression of medical research has lead to huge revenues for health care corporations, and has made many health care executives exceedingly rich, and many of the health care professionals and academic leaders who have enabled or implemented research suppression somewhat rich.  In the face of such perverse incentives, until we end the impunity of those who suppress medical research (and by the way, those who authorize, direct, or implement all sorts of other unethical, criminal and corrupt behavior we discuss on Health Care Renewal) things will not get better.  I can only hope that having this subject appear in a New York Times op-ed may lead to some real progress.

Oh, the Prices we Pay ... for Questionable Drug Marketing to Enrich Corporate Insiders - the Case of Questcor's H P Acthar Revisited

In 2007, we first discussed the case of the amazing pricing of H P Acthar, a very old drug of questionable usefulness, as an example of the irrationality of health care prices in the US, and of the failure of the organizations that ought to resist outrageous pricing in our mixed, pseudo-market based health care system to do so.  A recent New York Times article has updated this case.

Background

As we wrote in 2007, ACTH (adrenocorticotrophic hormone) is a naturally occurring hormone that stimulates the activity of the adrenal gland, which produces cortisol and other glucocorticoid and mineralocorticoid hormones.   ACTH produced from pigs' adrenals was first marketed as a biologic agent in the 1940s.  It was used for some conditions that appear to benefit from the effects of increasing cortisol production induced by ACTH.

It has been traditionally used to treat infantile spasms, a rare but distressing condition, and exacerbations of multiple sclerosis (MS).  However, since the drug was introduced so long ago, it was never subject to rigorous controlled trials to assess its efficacy and adverse effects for these indications.  Furthermore, since the 1940s, synthetic glucocorticoid hormones have become widely available as generic drugs.  Yet these slightly newer drugs have never been rigorously compared to ACTH for infantile spasms or MS.  The most recent review (edited in 2009) by the Cochrane Collaboration found that steroids and ACTH have some evidence in their favor for the treatment of acute MS, but found no evidence showing that ACTH was superior.  [Filippini G, Brusaferri F, Sibley WA, Citterio A, Ciucci G, Midgard R, Candelise L. Corticosteroids or ACTH for acute exacerbations in multiple sclerosis. Cochrane Database of Systematic Reviews 2000, Issue 4. Art. No.: CD001331. DOI: 10.1002/14651858.CD001331].  Also, the most recent review (edited in 2009) of treatment of infantile spasms concluded, "it is not clear which treatment [including ACTH] is optimal." [Hancock ED, Osborne JP, Edwards SW. Treatment of infantile spasms.  Cochrane Database of Systematic Reviews 2008, Issue 4. Art. No. : CD001770. DOI: 10.1002/14541858.CD001700.pub2.]

The Pricing of H P Acthar

Possibly because some physicians thought ACTH might be useful for some patients with two conditions, infantile spasms and acute exacerbations of MS, ACTH has remained on the market.  It was manufactured by a single company, Aventis, (now part of Sanofi-Aventis), the successor to Rhone-Poulenc-Rorer.  In 2001, Aventis sold the rights to manufacture ACTH, with the trade name H P Acthar, to a new, small biotechnology company, Questcor.  In 2007, Questcor raised the price of ACTH from $1650 per vial to more $23,000 per vial.  That got the attention of the Philadelphia Inquirer, on whose article we based our commentary. We used the price increase as an example of how pricing in health care has become untethered from any sort of clinical reality, and wondered why insurance companies and the US government seemed willing to pay this outrageous price for an old drug with little evidence from clinical research to support its use.  But the issue then seemed, like many others we have discussed , to become anechoic, until the very end of 2012.


Now the  New York Times story has provided an example of how health care corporations can do very well without doing anyone, except corporate insiders, much good.  It included instances of many of the kinds of ethically questionable practices we have discussed over the years on Health Care Renewal.

Deceptive Marketing

Per the NY Times,
Questcor did almost no research or development to bring Acthar to market, merely buying the rights to the drug from its previous owner for $100,000 in 2001. And while the manufacturing of Acthar is complex, it accounts for only about 1 cent of every dollar that Questcor charges for the drug.

Moreover, the tiny 'orphan' market soon became much bigger. Before long, Questcor began marketing the drug fo multiple sclerosis, nephrotic syndrome and rheumatologic conditions, even though there is little evidence that Acthar is more effective for those other conditions than alternatives that are far cheaper. And the company did so without being required to prove that the drug actually works. That is because Acthar was approved for use in 1952, before the Food and Drug Administration required clinical trials to show a drug is effective for a particular disease. Acthar is essentially grandfathered in. 

Today, only about 10 percent of the drug’s sales are for infantile spasms. The new uses, Mr. Bailey has told analysts, represent multibillion-dollar opportunities for Acthar and Questcor, its sole maker. 

The results have been beyond even the company’s wildest dreams. Sales of Acthar, which accounts for essentially all of Questcor’s sales, totaled nearly $350 million in the first nine months this year, up 145 percent from the period a year earlier. In the same period, Questcor’s earnings per share nearly tripled, to $2.12. In the five years after the big Acthar price increase in August 2007, Questcor shares rose from around 60 cents to about $50, in one of the best performances of any stock in any industry. 

So Questcor leadership was clever enough to use loopholes in the law to promote ACTH for particular kinds of patients without any good evidence that it did those patients any good.  Furthermore, Questcor used several questionable tactics 
in this promotion.

Manipulated Research

Apparently Questcor leaders decided they needed some sort of minimal research results to promote their products, so as the Times reported,

Because Acthar was approved for these conditions decades ago, Questcor has not had to do large clinical trials to show that the drug works. It has paid for some small studies, mainly by individual doctors, who then publish a paper that the sales force can present to doctors. 

The study that justified calling on rheumatologists involved five patients with rare conditions, all of them treated by a single doctor. All the patients had much improvement on Acthar after failing to benefit from more standard therapies, the doctor, Todd Levine, said in a Questcor conference call.

Too call the research Questcor sponsored minimalist would be too polite.  A case series of five patients, lacking any control group proves almost nothing.  It proves less when the research is done in an unblinded  fashion by a single doctor who presumably was invested in the outcome being favorable for his sponsor's product.  (I suppose some might quibble with calling this research manipulated, but I contend but doing such crude research when it would be possible to do something much more credible amounts to manipulation.)

Suppression of Research

Moreover, it seems that even such rudimentary studies sometimes failed to produce the wanted results.  In these cases, the Times reported that Questcor simply suppressed them.

Still, it appears that at least a couple of small studies that may have raised questions about the drug have been suspended. 

'From my standpoint it just didn’t work,' said Dr. Sungchun Lee, a Phoenix nephrologist who stopped a small study testing Acthar as a treatment for nephrotic syndrome. 'I think they were O.K. with me stopping because we weren’t getting the results,' he said. 

Another study that was terminated sought to determine whether multiple sclerosis patients who did not have a good response to steroids should be treated with either another round of steroids or with Acthar. The study was halted midway through 'to analyze data,' according to the summary of the trial on the federal clinical trial database. 

Use of Paid Key Opinion Leaders

Despite the lack of good clinical evidence in support ACTH, there are some physicians who defend its use.  One example in the Times article was a physician who is paid by Questcor

But some doctors say Acthar can be effective in cases that are not well treated by steroids. They say that there is emerging evidence that Acthar does more than just stimulate the body to produce its own steroids. 

'It really looks like the ACTH does bring something different to the table that standard steroids don’t,' said Dr Ben W Thrower, director of the multiple sclerosis institute at the Shepherd Center, a hospital in Atlanta. Dr. Thrower, who is a paid speaker for Questcor, said his institute had tried Acthar for about 60 of its 3,000 patients, ones who did not respond to steroid treatment. Acthar made the symptoms subside in about half of them.
Where to begin?  Just because ACTH is different does not mean it is better.  Since MS is a disease whose symptoms wax and wane, patients who fail standard treatment may get better on their own, and without a control group, it is impossible to say whether the ACTH given to such patients was the reason they got better. 

Creation of Institutional Conflicts of Interest for Disease Specific Foundations

Questcor's ACTH also has support from a disease specific foundation, but one that Questcor has also supported financially.

Dr Lawrence Brown, a neurologist at the Children's Hospital of Philadelphia, and the president of the Child Neurology Foundation, says of Questcor: 'They have gone out of their way to help every kid who needs the medicine to get it quickly and efficiently.'

This year, the foundation awarded its first corporate citizenship award to Questcor. Dr. Brown says Questcor’s donations — the amount has not been disclosed to the foundation didn’t influence the award.

Who could be so naive to think that giving an organization funding might influence its actions?  After all, human response to financial incentives is the basis for most current economic thinking.

Insiders Get Rich

Admittedly, these questionable tactics did lead to an increase in "shareholder value,"  As the company's proxy statement boasted in 2011,

While we generated strong financial returns in 2011, we are most proud of our patient focus and investments in Questcor which we believe will generate sustainable value to our shareholders, employees, patients and all of the communities that we serve. We believe that our patient focus and commitment to generating sustainable value to all of our constituencies results in strong value creation for our shareholders.

However, as of today, Qustcor's share price has dropped to $26.74 from a peak of 53.42 in June, 2012, with most of the drop in December, 2012, around the time the Times article came out, according to Google Finance.  So whether share holder value will turn out to have increased in the long run is not clear. 

Meanwhile, some Questcor employees did very well.  The largess started with some drug representatives,

Questcor sales representatives who are lucky enough or skillful enough to have a big prescriber in their territory can reap bonuses of $50,000 a quarter, according to former employees of the company.

More highly placed corporate insiders did even better.

Executives are paid well, too. In 2009, Mr. Bailey, [the CEO]  hired his daughter Kirsten Fereday as director of business analytics and evaluation, a job that paid $275,000 in cash and stock last year. 

 Left out of the Times article, somewhat surprisingly, was what the top executives make.  Information from up to 2011 is publicly available, however, in proxy fillings.

In the company's 2012 proxy statement, we find the following figures for total compensation:
Don M Bailey, President and CEO - $4,546,230, up 192% of his compensation in $1,554,503 in 2009
Michael H Mulroy, Senior Vice President, Chief Financial Officer and General Counsel -  $1,749,891 (his first year)
Stephen L Cartt, Chief Operating Officer -  $2,298,308, up 168% from $855,460 in 2009
David J Medeiros, Executive Vice President and Chief Technical Officer - $1,232,556, up 78% from $692,188 in 2009
David Young Pharm D, Chief Scientific Officer - $1,948,804 up 182% from $1,066,159 in 2009

In addition, by 2011, Mr Bailey, the CEO, had acquired 1.92% of the company's total stock, 3,834,910 shares, today worth $102,545,490.

Finally, per the Times,

one group of shareholders has done pretty well for itself. Over the last two years, as the company’s share price mainly soared, Questcor insiders have sold more than $100 million of stock. 

Summary

 So, in summary, a small biotechnology company drastically increased the price of its only product, a drug which has never been subject to modern clinical trials, and whose efficacy has never been proven.  Its marketing tactics have included manipulation and suppression of research, and payments to physicians and non-profit organizations.  Although its most breathtaking price increases were made in 2007, they attracted little public attention until five years later.   Meanwhile, corporate insiders, from drug representatives to top executives and their relatives, have done very well for themselves.

In the US, there a lot of people who advocate free market based health care for its efficiency and innovation.  For example, see "Yes, Mr President, a Free Market Can Fix Health Care," published by the Cato Institute, in which its Director of Health Policy Studies proclaimed, "The great advantage of a free market is that innovation and more prudent decisionmaking means that fewer patients will fall through the cracks," and then "a free market can and would control costs, expand choice, improve health care quality, and make health coverage more secure." [italics added for emphasis]

Unfortunately, the case of Questcor's ACTH makes it seem that in the current US system, which is supposedly more market based than systems in many other countries, the efficiency and innovation is characteristic of the marketing of corporate health care, not of the health care itself.  Here is a stellar example of how clever, and not always very scrupulous marketing can be used to sell a very old drug with little demonstrated clinical value for a stratospheric price, enriching corporate insiders, perhaps enriching stockholders (although, not so much lately, and we will see how they do in 2013), at the expense of the public who pays taxes and insurance premium.  This case suggests a need for more attention to market failures and less insistence on market fundamentalism.  Of course, it also suggests the continuing need for health care professionals, policy makers, patients and the public to be extremely skeptical about heavily promoted commercial health products.

What If the Institute of Medicine Wrote a Report and Nobody Followed it? - the Case of the Standards for Developing Trustworthy Guidelines


For over 20 years, clinical practice guidelines (CPGs) have been touted to improve health care quality and control costs.  Enormous numbers of guidelines have been developed, but with seemingly little impact on health outcomes.  While some of those leading health care organizations have predictably blamed individual practitioners for obstinately ignoring or challenging guidelines, there is increasing evidence that maybe the guidelines themselves are part of the problem.

 An Example of a Guideline that Apparently was Not Trusted

One example Dr Wally Smith and I have taught in our recurring mini-course on why physicians fail to follow guidelines (and otherwise appear not to practice in accord with others' wishes) is that of the guidelines on management of depression in primary care.  Most existing guidelines urge physicians to screen patients for (presumably mild-to-moderate) depression and treat them aggressively, with emphasis on the use of the newer anti-depressants.  These guidelines, in turn, were based on numerous published randomized clinical trials that showed that these drugs were safe and efficacious.  Yet multiple studies showed that physicians failed to follow these guidelines, and various attempts to improve their adherence did little.  So for years the assumption was that physicians at best experienced practical and system barriers to follow these guidelines, and at worst were ill-informed or irrational. 


However, information that came out gradually during the early part of the 21st century suggested that perhaps the problem was within the guidelines, not the health care professionals.  First, documents produced during New York Attorney General Eliot Spitzer's lawsuit against GlaxoSmithKline about the marketing of one of these drugs (Paxil, paroxetine) suggested that the company had suppressed clinical trial data that reflected poorly on the drug (See Kondro W.  Drug company experts advised staff to withold data about SSRI use in children.  Can Med Assoc J 2004; 170: 783.  Link here.)    These suspicions were later fleshed out  by consideration of documents further disclosed in litigation (e.g., see this post and its links).  Then several studies, most particularly that by Erick Turner and colleagues, showed that numerous trials of new anti-depressants had been suppressed, that is, never published (Turner et al. Selective publication of antidepressant trials and its influence on apparent efficacy. N Engl J Med 2008; 358:252-260.  Link here).  When the results of these trials were added to those that were published, the efficacy of anti-depressants was no longer so clear.  So maybe the guidelines that physicians did not follow were not trustworthy, and should not have been followed in the first place.

Would IOM Standards to Improve Guideline Trustworthiness Help?

So in 2011, the prestigious Institute of Medicine released a report on the development of  better standards to produce more trustworthy guidelines (Clinical Practice Guidelines We Can Trust.  Link here.)  We posted about that report here, but noted that it was receiving little other attention, an example of the anechoic effect. 

A few weeks ago, an article appeared documenting a study meant to assess the the trustworthiness of clinical practice guidelines published soon after the IOM report.  Its title telegraphs the results. ( Kung J, Miller RR, Mackowiak PA. Failure of clinical practice guidelines to meet Institute of Medicine standards: two more decades of little, if any progress.  Arch Intern Med 2012.  Link here.)

Methods and Results

The investigators selected a random sample of 114 individual guidelines available during June, 2011 stratified by 26 clinical topics. The versions of the guidelines used were those archived in the National Guideline Clearinghouse (NGC) maintained by the Agency for Healthcare Research and Quality (AHRQ).


The goal of the study was to "examine adherence to the IOM standards" by guidelines published after the standards were published.  Actually, the study only assessed adherence to 18 of the 25 standards espoused by the IOM (because the remaining seven were "too vague and subjective to be analyzed.")

Furthermore, the criteria used to determine if a specific guideline met each of the three items above were rather lax:


In evaluating each guideline summary, care was taken to be as liberal as possible in considering that a standard was met when the individual guideline summary provided any information pertaining to that particular standard.

Nevertheless, using these lax standards to only evaluate adherence to 18/25 guidelines, the authors found that "the overall median number of IOM standards satisfied (out of 18) was 8 (44.4%) ....  Fewer than half of the guidelines surveyed met more than 50% of the IOM standards."

An examination of the details of the study's methods reveals things are even worse than that.

Analyzing the Study's Methods to Find that Things Are Worse Than They Seem

Review of the study's methods show that they provided a very optimistic view of adherence to the IOM standards.  As noted above, the study did not look for adherence to all of the IOM standards.  Moreover, those they did consider were simplified and made less rigorous.  For example, Standard 2 from the IOM on management of conflict of interest (COI) was:

  STANDARD 2
Management of conflict of interest (COI)

2.1
Prior to selection of the Guideline Development Group (GDG), individuals being considered for membership should declare all interests and activities potentially resulting in COI with development group activity, by written disclosure to those convening the GDG.
- Disclosure should reflect all current and planned commercial (including services from which a clinician derives a substantial proportion of income), non-commercial, intellectual, institutional, and patient/public activities pertinent to the potential scope of the CPG.

2.2
Disclosure of COIs within GDG
- All COI of each GDG member should be reported and discussed by the prospective development group prior to the onset of their work.
- Each panel member should explain how their • COI could influence the CPG development process or specific recommendations.

2.3
Divestment
- Members of the GDG should divest themselves of financial investments they or their family members have in, and not participate in marketing activities or advisory boards of, entities whose interests could be affected by CPG recommendations.

2.4
Exclusions
- Whenever possible GDG members should not have COI.
- In some circumstances, a GDG may not be able to perform its work without members who have COIs, such as relevant clinical specialists who receive a substantial portion of their incomes from services pertinent to the CPG.
- Members with COIs should represent not more than a minority of the GDG.
- The chair or co-chairs should not be a person(s) with COI.
- Funders should have no role in CPG development.

However, the study boiled all this down to three items:
-  COIs stated
-  Chair has COI
-  Co-chairperson has COI

Thus the study did not address standards requiring full and complete disclosure (not just some disclosure) of all COIs; consideration of how the COIs might influence the particular guideline; divestment of specific types of conflicts of interest, that is, financial investments, and cessation of participation in marketing activities or advisor boards; minimization of conflicts of all members of the committee; and barring of participation of funders in guideline development.

Even so, the guidelines assessed did a very poor job upholding even these few liberalized standards regarding conflicts of interest.  Of the guidelines assessed, less than half, 46.8% provided ANY disclosure of conflicts of interest.  Those written by sub-specialty societies were particularly opaque in this regard.  Less than one-third, 29.3%, provided any disclosure.  Thus the majority of guidelines assessed were not at all transparent about conflicts of interest affecting the guideline development process.

Furthermore, of the 46.8% of all the guidelines which made any disclosures of conflicts of interest, 71.4% admitted their chair people HAD a conflict of interest.  Thus, only (0.468 * [1 - .714]) = 13.3% provided assurance that they fulfilled the single requirement (from standard 2.4 above) that the chair person did not have a COI.  For the guidelines written by sub-specialty societies, by a similar calculation, only 12.2% provided an assurance that the chair had no COI.  (The proportions providing assurance that the co-chair people had no COI were even lower.)  Thus the vast majority of guidelines did not clearly follow two straight-forward standards for minimizing the effects of conflict of interest, that the guideline committee chair and co-chair should not have any relevant conflicts. 

Given the miserable results concerning even minimal adherence to some of the IOM report's conflict of interest standards, it is likely that almost no published guidelines from 2011 came close to fulfilling the full set of IOM standards.  Despite the best efforts of the IOM, it appears that guideline developers have not progressed at all towards providing trustworthy guidelines. 

Summary

An editorial (Shaneyfelt T. In guidelines we cannot trust.  Arch Intern Med 2012) accompanying the article by Kung and colleagues summarized its results thus:

The same problems that have plagued guideline development continue to plague guideline development; namely, their variable and opaque development methods, their often conflicted and limited panel composition, and their lack of significant external review by stakeholders throughout the development process.   As a result, the trustworthiness of guidelines is limited.

While guidelines may have seemed to be a promising method to improve health care in the early 1990s, they have failed to live up to that promise.  Shaneyfelt was not optimistic they would improve in the future:

I am not optimistic that much will improve.  No one seems interested in curtailing the out-of-control guideline industry.

On the other hand, in my humble opinion, it is not that on one is interested in better guidelines.  It would clearly be in the best interests of patients and the public, and of health care professionals who care about the quality of their practice and the outcomes of their patients to curtail that industry.  The issue is why patients', the public's, and professional's interests were ignored.

Neither Shaneyfelt nor Kung et al discussed why there has been so little attention to patients' and the public's health, and to health care professionalism in all this.  For a quick answer, we do not have to look far on Health Care Renewal


In fact, the IOM report on guideline development from 2011 was a serious challenge to the powers that be in health care.  In particular, it challenged the cozy relationships that had grown up among the organizations that undertook guideline development and the health care professionals on guideline panels on one hand and organizations that stand to gain were specific guidelines to favor their products, services, and agendas on the other.  The standards mandated transparency and honesty about conflicts of interest affecting guideline committees and the organizations which assembled them, and if upheld would have greatly reduced these relationships.

Now it turns out that the guideline standards have been honored mainly in the breach.  Of course, these standards, while increasing trustworthiness, would have cost a lot of medical societies considerable commercial funding, and would have cost a lot of health care professionals on guideline panels considerable personal wealth.  These standards would probably also have cost a lot of companies whose products and services were addressed by guidelines to lose revenue.  So it is not surprising that the IOM standards were ignored.  Their implementation would have cost too many people who are financially benefiting from the status quo too much money.  And these people, that is, leaders of professional societies dependent on commercial outside funding, health care professionals and academic used to financial support from commercial interests, and health care corporations are good at making sure their interests are not ignored, even if their interests conflict with those of patients, the public, and well-intentioned health care professionals.  

So, the flouting of the well reasoned IOM guideline standards adds one more reason for patients and the general public to distrust modern health care and all those who "deliver" it, even to distrust well-intentioned health care professionals who have not been able to distinguish themselves from their colleagues who are too happy to help commercial interests while taking commercial money.  If health care professionals want to regain the public's trust, they could do worse than publicly declaring their intention to show that their practice in the future will be guided by trustworthy guidelines based on clinical research evidence and knowledge of biomedical science, drawn up by health care professionals independent of commercial interests.

When Clinical Trials are Meant for Marketing, not Science

The development of the randomized controlled clinical trial (RCT) was one of the major scientific advances in clinical medicine.  RCTs provide a major part of the evidence underlying evidence based medicine.  RCTs provide a major source of data used by the US Food and Drug Administration, and similar agencies in other countries, to decide whether to approve drugs or devices to manage particular clinical problems.  Unfortunately, with the rise of the RCT came a rise in attempts to suppress and manipulate clinical trials by those with vested interests, often in selling the products and services the trials can evaluate.

Many of the examples we have discussed were of attempts at manipulation or suppression of clinical trials originally done to provide evidence for product approval, or even ostensibly to advance clinical science.  Yet a relatively new article covering evidence revealed from litigation about the drug gabapentin (Neurontin) originally made by Parke-Davis, first a part of Warner Lambert, now part of Pfizer suggests that many clinical trials may not be done to advance science, or even just to provide data to regulators, but only to market products.

The article is Vedula SS, Goldman PS, Rona IJ, Greene TM, and Dickersin K. Implementation of a publication strategy in the context of reporting biases: a case study based on new documents from the Neurontin litigation.  Trials 2012; 13: 136.  Link here.

Methods Summary

The article described a case study based on documents revealed in 2008 litigation.  The purpose of the study was:

to describe the implementation of a publication strategy for off-label marketing of gabapentin, within the context of reporting biases and spin of Pfizer and Parke-Davis’s clinical trial findings, for four off-label uses: migraine prophylaxis, treatment of bipolar disorders, neuropathic pain, and nociceptive pain. 

The study examined documents revealed through the 2008 litigation.  It concentrated on documents relating to the marketing of Neurontin for four off-label indications, that is, for four potential reasons to use the drug which had not yet been approved by the US FDA.  It focused on documents discussing strategies for marketing for these indications, and then documents about particular company sponsored RCTs done for these indications.

Strategies to Sell Drugs

The documents examined by the investigators showed that Parke-Davis prepared "marketing assessments" for four possible indications for Neurontin.  The assessments discussed two possible strategies.  The "indication strategy" would be to conduct trials for the purposes of providing data to the FDA in the hope that the FDA would then approve the new indication for the drug.  The "marketing strategy" would be, in the words of an internal company memo quoted in the study, to conduct clinical trials and

to disseminate the information as widely as possible through the world’s medical literature

In other words, the publication strategy involved using RCTs first for marketing, rather than scientific or regulatory purposes.

How the Trials were Controlled by Marketers 

The publication strategy involved not simply doing trials and publicizing their results, but controlling the messages conveyed by the trials to make sure they primarily supported marketing.  This was done by having the company's marketing department control the content of the trial reports.

 A Neurontin Publications Subcommittee (NTN PSC) was formed within Pfizer and Parke-Davis to implement a publication plan. Minutes from meetings between the NTN PSC and Medical Action Communications (MAC), a medical writing company, indicate that a list of key messages, guiding the content of published reports related to the trials of gabapentin for off-label indications, was developed based on a branding guide
Thus it appeared to be that marketers, not physicians or scientists were in control of supposedly scholarly research publications appearing in medical journals.

The marketers controlled content by controlling those who wrote it.

 A standard operating procedure related to publication of affiliate-driven manuscripts was identified in internal company documents dated October 16, 2002, and it sheds further light on the publication planning process (see Figure 3). (The term affiliate in this context refers to Pfizer’s foreign affiliates, that is, corporations related to Pfizer by either shareholdings or other means of control, including subsidiary, parent, or sibling corporations). According to the internal company documents, 'affiliate-driven manuscripts' were written for Pfizer and Parke-Davis by MAC and sent to the authors for approval. Each article was coordinated by a manuscript team, consisting of representatives from the medical and marketing divisions of the company. The documents also indicate that all affiliate-driven manuscripts should be forwarded to the NTN PSC for review. One of the objectives of manuscripts being reviewed by the NTN PSC was to ‘ensure that they are in-line with current product messages and areas of interest’
Manipulating the Dissemination (and Analysis) of Research Results

Note that the control of publication by marketers describe above involved ghost-writing of articles by medical education and communications companies (MECCs).  Later the article explained that these ghost writers were "not appropriately acknowledged" in the resulting published articles.

The Vedula et al study article provided examples of "spin" in the writing of again supposedly scholarly research publications used in fact to support marketing, and controlled if not composed by marketers.

 We identified spin in publications related to 8/12 trials included in our analysis.... We classified the following as spin: emphasis in the published report on outcomes that were not specified in the study protocol (Study 879–201) ...; conclusions that did not match study findings described in the internal company research report (Study 945–220) ...; extensive rationale to explain away statistically non-significant (unfavorable to the sponsor) findings (Study 945–209; 945–291; No study number - Gorson) ...; conclusion of treatment effectiveness from an uncontrolled study (Study 945–250) ...; emphasis on statistically significant secondary outcomes despite negative findings for the primary outcome (Study 945–271) ...; and an explicit description of an attempt to spin study findings (as described in internal company emails) (Study 945–306).

Note that while most of these examples of spin involved manipulation of the dissemination of study results, that is, doubtful, biased or fallacious arguments based on apparently unbiased data, they also involved manipulation of the analyses (in italics). 

The article also described manipulation of dissemination involving the timing of publication, including delaying publication of an article despite the wishes of the study's investigators because the results were not statistically significant, and hence not favorable for marketing. 

Summary

Documents revealed by litigation about Neurontin in 2004 provided insights about how pharmaceutical and presumably other kinds of health care corporations may conduct systematic, deceptive stealth marketing campaigns to promote their products and services (look here).  We noted that initial media coverage of documents revealed in the 2008 litigation also suggested the existence of a systematic "publication strategy" to control dissemination of results of particular trials, while suppressing trials whose results could not easily be spun to provide support of marketing objectives (look here).

Now the new paper by Verdula et al fill out our knowledge of this case.  The paper suggests that randomized controlled clinical trials may be done not to advance science, or even convince regulators, but primarily to market their sponsors' products.  Thus some significant proportion of the clinical research literature, the literature that physicians and other health professionals have relied upon to make evidence-based decisions for their patients, may exist mainly for marketing purposes.  Even the most rigorous methods used by clinical epidemiologists to review research are meant to discover problems that arose from human error or the inevitable trade-offs made when research is done in the real world, but not deliberately introduced biases and defects meant to promote vested interests.  Thus it is not clear that even the most "evidence-based" medical decisions are based on real scientific evidence rather than the spinning of marketers.

Thus health care professionals, policy makers, researchers, and the interested public need to be even more skeptical about arguments made to promote innovative treatments and other clinical interventions.  However, it is not clear that even rigorous skepticism can defend the integrity of evidence based medicine from marketing disguised as clinical research.

Going forward, we must consider erecting an impregnable barrier between clinical research and those whose primary interest is to make money by selling health care goods and services.  If we do not do that, we will forever need to worry that we really have no idea what "works in medicine," and whether any particular test, treatment, or program provides benefits that outweigh its harms.
