Last December, Brown University’s Dr. David Egilman and colleagues published a scholarly paper that identified serious flaws in a study of a hip prosthesis, and accused the medical device maker DePuy — a wholly owned subsidiary of J&J — of “grave fraudulence.”
“J&J/DePuy violated the study protocol and manipulated data; consented participants in violation of standards protecting human subjects; and did not secure Institutional Review Board approval for all study sites,” they wrote about a clinical trial of the companies’ Pinnacle metal-on-metal hip replacement system, which was taken off the market in 2013 after many patients had to have the artificial hips removed.
The study, they argued based on an analysis of internal company documents, was nothing more than a “seeding study,” designed to market the device to doctors rather than present a test of its safety or efficacy.
The study formed the basis of several papers published starting in 2007 and seemed to show that the system worked well for five years, with a low rate of serious complications. According to Egilman and colleagues, “J&J/DePuy subsequently utilized the 99.9% survivorship at five years — which the Worldwide Vice President of Clinical Research admitted did ‘not accurately reflect the data that was at the [surgeon investigator] sites’ — in marketing materials to claim that their hip implant had a nearly perfect success rate.”
Now, J&J is demanding that the article be retracted. In a six-page letter to Taylor & Francis, which publishes the journal where the paper appeared, J&J biostatistician Jim Lesko wrote that it “contains numerous factual errors that undermine its conclusions. Moreover, the authors have omitted and failed to disclose substantial conflicts of interest.”
The Pinnacle hip study wasn’t a seeding study, he said, because “the sponsor implemented sound scientific research practices” and it “had a clearly defined scientific objective.” Whatever marketing the company was able to use the study for, “these marketing benefits did not impact the scientific integrity of the study,” he wrote.
Lesko wrote in the April 18 letter — obtained by STAT — that if the journal, Accountability in Research, refused to retract the paper, he wants the letter considered for publication. “Because the topics discussed in the AIR Article and in this response are all part of ongoing litigation involving the Pinnacle MOM device, I have consulted with DePuy’s attorneys in preparing this response,” he noted.
The mention of litigation gives a hint of the bigger picture here: Some 10,000 recipients of the Pinnacle hip have sued J&J, which in turn has been ordered to pay hundreds of millions of dollars to plaintiffs who claimed the device caused metal poisoning or tissue damage. (The company is appealing the judgements, and denies the product was defective.) Egilman and his co-authors have served as expert witnesses for some of those plaintiffs.
For their part, Egilman and his colleagues — in a 32-page letter rebutting J&J’s claims — wrote that they “provided the final draft of our paper to J&J/DePuy for comments and correction one month before publication” but received no response. They also noted that the paper disclosed their involvement in the litigation. The authors said they would welcome publication of Lesko’s letter alongside their own.
“Needless to say this is a baseless request and merely an effort to bully the medical and scientific community to acquiesce to corporate crime never mind irresponsible and unethical conduct,” Egilman wrote in an email to Taylor & Francis.
Battling pharma is nothing new for Egilman. In 2007, he agreed to pay Eli Lilly$100,000 for leaking confidential documents about the company’s antipsychotic drug Zyprexa. Egilman was a consultant for the Department of Justice in a related case in which Lilly would eventually plead guilty to off-label marketing and settle for $1.4 billion. He has written critically of Merck’s failures to disclose troubling data about Vioxx, and testified in litigation against J&J over use of talc in their powders.
It’s worth noting that retractions are hardly the only way to respond to potential issues in the literature. A detailed letter pointing out alleged errors — which J&J has done here — but without a call for retraction is less likely to make authors and journals defensive. Of course, you can also go to the media to exert pressure on a journal, something that J&J did not do in this case. Public attention tends to have an effect.
As of now, the Accountability in Research paper has not been retracted, and after a discussion with the journal, J&J said it was not interested in publishing Lesko’s letter. However, the company continues to seek retraction of the paper, spokeswoman Mindy Tinsley told STAT, and a spokesperson for Taylor & Francis said it is looking into the matter.
Science often plays out like a game of ping pong, as researchers advance hypotheses only to have them rebutted — and then return with a rebuttal of their own. But if readers are going to subject themselves to whiplash, it’s better if the game being played is in the service of knowledge, not lawyers.
