The Knowledge Remedy Proposal

November 14th, 2020

Alexandra D. Lahav is the Ellen Ash Peters Professor of Law at the University of Connecticut School of Law. This year’s symposium issue of the Texas Law Review has published Professor Lahav’s article, “The Knowledge Remedy,” which calls for the imposition of a duty to conduct studies by defendants, to provide evidence relevant to plaintiffs’ product liability claims. Alexandra D. Lahav, “The Knowledge Remedy,” 98 Texas L. Rev. 1361 (2020) [cited as Lahav].

Professor Lahav’s advocated reform is based upon the premises that (1) the requisite studies needed for causal assessment “are too costly for plaintiffs to fund,” (2) are not done by manufacturers, or (3) are not done in good faith, and (4) are not conducted or adequately funded by government. Lahav believes that plaintiffs are injured by exposure to chemicals but they cannot establish causation in court because the defendant “hid its head in the sand,” or worse, “engaged in misconduct to prevent or hide research into its products.”[1] Lahav thus argues that when defendants have been found to have engaged in misconduct, courts should order them to fund studies into risks posed by their products.

Lahav’s claims are either empty or non-factual. The suggestion that plaintiffs are injured by products but cannot “prove” causation begs the question how she knows that these people were injured by the products at issue. In law professors’ language, Lahav has committed the fallacy of petitio principia.

Lahav’s poor-mouthing on behalf of claimants is factually unsupported in this article. Lahav tells us that:

“studies are too expensive for individuals or even groups to fund.”

This is assertion is never backed up with any data or evidence about the expense involved. Case-control studies for rare outcomes suffer from potential threats to their validity, but they can be assembled relatively quickly and inexpensively. Perhaps a more dramatic refutation of Lahav’s assertions come from the cohort studies done in administrative databases, such as the national healthcare databases of Denmark or Sweden, or the Veterans’ Administration database in the United States. These studies involve querying existing databases for the exposures and outcomes of interest, with appropriate controls; such studies are frequently of as high quality and validity as can be had in observational analytical epidemiology.

There are, of course, examples of corporate defendants’ misconduct in sponsoring or conducting studies. There is also evidence of misconduct in plaintiffs’ sponsorship of studies,[2] and outright fraud.[3] And certainly there is evidence of misconduct or misdirection in governmentally funded and sponsored research, sometimes done in cahoots with plaintiffs’ counsel.[4]

Perhaps more important for the intended audience of the Texas Law Review, Lahav’s assertion is demonstrably false. Plaintiffs, plaintiffs’ counsel, and plaintiffs’ advocacy groups have funded studies, often surreptitiously, in many litigations, including those involving claims of harm from Bair Hugger, asbestos, silicone gel breast implants, welding fume, Zofran, isotretinoin, and others. Lahav’s repetition of the claim does not make it true.[5] Plaintiffs and their proxies, including scientific advocates, can and do conduct studies, very much with a view toward supporting litigation claims. Mass tort litigation is a big business, often run by lawyer oligarchs of the plaintiffs’ bar. Ignorantia facti is not an excuse for someone who argues for a radical re-ordering of an already fragile litigation system.

Lahav also complains that studies take so long that the statute of limitations will run on the injury claims before the scientific studies can be completed. There is a germ of truth in this complaint, but the issue could be resolved with minor procedural modifications. Plaintiffs could be allowed a procedure to propound a simple interrogatory to manufacturing firms to ask whether they believe that causality exists between their product and a specific kind of harm, or whether a claimant should reasonably know that such causality exists to warrant pursuing a legal claim. If the manufacturers answer in the negative, then the firms would not be able to assert a limitations defense for any injury that arose on or before the date of its answer. Perhaps the court could allow the matter to stay on its docket and require that the defendant answer the question annually. Plaintiffs and their proxies would be able to sponsor studies necessary to support their claims, and putative defendants would be on notice that such studies are underway.

Without any serious consideration of the extant regulations, Lahav even extends her claims of inadequate testing and lax regulation to pharmaceutical products, which are subject to extensive requirements of showing safety and efficacy, both before and after approval for marketing. Lahav’s advocacy ignores that an individual epidemiologic study rarely “demonstrates” causation, and many such studies are required before the scientific community can accept the causal hypothesis as “disproven.” Lahav’s knowledge remedy is mostly an ignorance ruse.

Hacking at the “A” Cell

November 10th, 2020

At the heart of epidemiologic studies and clinical trials is the contingency table. The term, contingency table, was introduced by Karl Pearson in the early 20th century as a way to explore the independence, vel non, in a multivariate model. The simplest version of the table is the “2 by 2” table that is at the heart of case-control and other studies:

  Cases (with outcome of interest) Controls (without outcome of interest)  
Exposure of Interest Present                A                  B A + B

Marginal total of all exposed

Exposure of Interest Absent                C                  D C + D

Marginal total of all non-exposed

  A + C

Marginal total of cases

B + D

Marginal total of controls

A + B + C + D

Total observed in study


A measure of association between the exposure of interest and the outcome of interest can be shown in the odds ratio (OR), which can be assessed for random error on the assumption of no association.

OR = (A/C)/(B/D) = A*D/B*C

The measurement of the OR turns on faithfully applying the same method of counting cases regardless of exposure status. When investigators expand the “A” cell by loosening their criteria for exposure, we say that they have engaged in “hacking the A cell.”

Something akin to hacking the A cell occurred in the large epidemiologic study, known as  “Yale Hemorrhagic Stroke Project (HSP),” which was the center piece of the plaintiffs’ case in In re Phenylpropanolamine Products Liability Litigation. Although the HSP was sponsored by manufacturers, it was conducted independently without any manufacturer oversight beyond the protocol. The FDA reviewed the HSP results, and ultimately the HSP was published in the New England Journal of Medicine.[1]

The HSP was challenged in a Rule 702 hearing in the Multi-District Litigation (MDL). The MDL judge, Judge Rothstein, conducted hearings and entertained extensive briefings on the reliability of plaintiffs’ expert witnesses’ opinions, which were based largely upon the HSP. The hearings, however, could not go beyond doubts raised by the published paper, and Judge Rothstein permitted plaintiffs’ expert witnesses’ proffered testimony based upon the study, finding that:

“The prestigious NEJM published the HSP results, further substantiating that the research bears the indicia of good science.”[2]

The HSP study was subjected to much greater analysis in litigation.  After the MDL concluded its abridged gatekeeping process, the defense successfully sought the underlying data to the HSP. These data unraveled the HSP paper by showing that the study investigators had deviated from the protocol in a way to increase the number of exposed cases (A cell), with the obvious result of increasing the OR reported by the study.

Both sides of the PPA litigation accused the other side of “hacking at the A cell,” but juries seemed to understand that the hacking had started before the paper was published. A notable string of defense verdicts ensued. After one of the early defense verdicts, plaintiffs’ counsel challenged the defendant’s reliance upon underlying data that went behind the peer-reviewed publication.  The trial court rejected the request for a new trial, and spoke to the significance of challenging the superficial significance of peer review of the key study relied upon by plaintiffs in the PPA litigation:

“I mean, you could almost say that there was some unethical activity with that Yale Study.  It’s real close.  I mean, I — I am very, very concerned at the integrity of those researchers. Yale gets — Yale gets a big black eye on this.”[3]

Today we can see the equivalent of “A” cell hacking in a rather sleazy attempt by the Banana Republicans to steal a presidential election they lost. Cry-baby conservatives are seeking recounts where they lost, but not where they won. They are challenging individual ballots on the basis of outcome. They are raising speculative questions about the electoral processes of entire states, even where the states in question have handed them notable wins down ballot.

Data Games – A Techno Thriller

April 22nd, 2020

Data Games – A Techno Thriller

Sherlock Holmes, Hercule Poirot, Miss Marple, Father Brown, Harry Bosch, Nancy Drew, Joe and Frank Hardy, Sam Spade, Columbo, Lennie Briscoe, Inspector Clouseau, and Dominic Da Vinci:

Move over; there is a new super sleuth in town.

Meet Professor Ken Wheeler.

Ken is a statistician, and so by profession, he is a data detective. In his day job, he teaches at a northeastern university, where his biggest challenges are managing the expectations of students and administrators, while trying to impart statistical learning. At home, Ken rarely manages to meet the expectations of his wife and son. But as some statisticians are wont to do, Ken sometimes takes on consulting gigs that require him to use his statistical skills to help litigants sort out the role of chance in cases that run from discrimination claims to rare health effects. In this contentious, sharp-elbowed environment, Ken excels. And truth be told, Ken actually finds great satisfaction in identifying the egregious errors and distortions of adversary statisticians

Wheeler’s sleuthing usually involves ascertaining random error or uncovering a lurking variable, but in Herberg I. Weisberg’s just-published novel, Data Games: A Techno Thriller, Wheeler is drawn into a high-stakes conspiracy of intrigue, violence, and fraud that goes way beyond the run-of-the-mine p-hacking and data dredging.

An urgent call from a scientific consulting firm puts Ken Wheeler in the midst of imminent disaster for a pharmaceutical manufacturer, whose immunotherapy anti-cancer wonder drug, Verbana, is under attack. A group of apparently legitimate scientists have obtained the dataset from Verbana’s pivotal clinical trial, and they appear on the verge of blowing Verbana out of the formulary with a devastating analysis that will show that the drug causes early dementia. Wheeler’s mission is to debunk the debunking analysis when it comes.

For those readers who are engaged in the litigation defense of products liability claims against medications, the scenario is familiar enough. The scientific group studying Verbana’s alleged side effect seems on the up-and-up, but they appear to engaged in a cherry-picking exercise, guided by a dubious theory of biological plausibility, known as the “Kreutzfeld hypothesis.”

It is not often that mystery novels turn on surrogate outcomes, biomarkers, genomic medicine, and predictive analytics, but Data Games is no ordinary mystery. And Wheeler is no ordinary detective. To be sure, the middle-aged Wheeler drives a middle-aged BMW, not a Bond car, and certainly not a Bonferroni. And Wheeler’s toolkit may not include a Glock, but he can handle the lasso, the jacknife, and the logit, and serve them up with SAS. Wheeler sees patterns where others see only chaos.

Unlike the typical Hollywood rubbish about stereotyped evil pharmaceutical companies, the hero of Data Games finds that there are sinister forces behind what looks like an honest attempt to uncover safety problems with Verbana. These sinister forces will use anything to achieve their illicit ends, including superficially honest academics with white hats. The attack on Verbana gets the FDA’s attention and an urgent hearing in White Oak, where Wheeler shines.

The author of Data Games, Herbert I. Weisberg, is himself a statistician, and a veteran of some of the dramatic data games he writes about in this novel. Weisberg is perhaps better known for his “homework” books, such asWillful Ignorance: The Mismeasure of Uncertainty (2014), and Bias and Causation: Models and Judgment for Valid Comparisons (2010). If, however, you ever find yourself in a pandemic lockdown, Weisberg’s Data Games: A Techno Thriller is a perfect way to escape. For under $3, you will be entertained, and you might even learn something about probability and statistics.

April Fool – Zambelli-Weiner Must Disclose

April 2nd, 2020

Back in the summer of 2019, Judge Saylor, the MDL judge presiding over the Zofran birth defect cases, ordered epidemiologist, Dr. Zambelli-Weiner to produce documents relating to an epidemiologic study of Zofran,[1] as well as her claimed confidential consulting relationship with plaintiffs’ counsel.[2]

This previous round of motion practice and discovery established that Zambelli-Weiner was a paid consultant in advance of litigation, that her Zofran study was funded by plaintiffs’ counsel, and that she presented at a Las Vegas conference, for plaintiffs’ counsel only, on [sic] how to make mass torts perfect. Furthermore, she had made false statements to the court about her activities.[3]

Zambelli-Weiner ultimately responded to the discovery requests but she and plaintiffs’ counsel withheld several documents as confidential, pursuant to the MDL’s procedure for protective orders. Yesterday, April 1, 2020, Judge Saylor entered granted GlaxoSmithKline’s motion to de-designate four documents that plaintiffs claimed to be confidential.[4]

Zambelli-Weiner sought to resist GSK’s motion to compel disclosure of the documents on a claim that GSK was seeking the documents to advance its own litigation strategy. Judge Saylor acknowledged that Zambelli-Weiner’s psycho-analysis might be correct, but that GSK’s motive was not the critical issue. According to Judge Saylor, the proper inquiry was whether the claim of confidentiality was proper in the first place, and whether removing the cloak of secrecy was appropriate under the facts and circumstances of the case. Indeed, the court found “persuasive public-interest reasons” to support disclosure, including providing the FDA and the EMA a complete, unvarnished view of Zambelli-Weiner’s research.[5] Of course, the plaintiffs’ counsel, in close concert with Zambelli-Weiner, had created GSK’s need for the documents.

This discovery battle has no doubt been fought because plaintiffs and their testifying expert witnesses rely heavily upon the Zambelli-Weiner study to support their claim that Zofran causes birth defects. The present issue is whether four of the documents produced by Dr. Zambelli-Weiner pursuant to subpoena should continue to enjoy confidential status under the court’s protective order. GSK argued that the documents were never properly designated as confidential, and alternatively, the court should de-designate the documents because, among other things, the documents would disclose information important to medical researchers and regulators.

Judge Saylor’s Order considered GSK’s objections to plaintiffs’ and Zambelli-Weiner’s withholding four documents:

(1) Zambelli-Weiner’s Zofran study protocol;

(2) Undisclosed, hidden analyses that compared birth defects rates for children born to mothers who used Zofran with the rates seen with the use of other anti-emetic medications;

(3) An earlier draft Zambelli-Weiner’s Zofran study, which she had prepared to submit to the New England Journal of Medicine; and

(4) Zambelli-Weiner’s advocacy document, a “Causation Briefing Document,” which she prepared for plaintiffs’ lawyers.

Judge Saylor noted that none of the withheld documents would typically be viewed as confidential. None contained “sensitive personal, financial, or medical information.”[6]  The court dismissed Zambelli-Weiner’s contention that the documents all contained “business and proprietary information,” as conclusory and meritless. Neither she nor plaintiffs’ counsel explained how the requested documents implicated proprietary information when Zambelli-Weiner’s only business at issue is to assist in making lawsuits. The court observed that she is not “engaged in the business of conducting research to develop a pharmaceutical drug or other proprietary medical product or device,” and is related solely to her paid consultancy to plaintiffs’ lawyers. Neither she nor the plaintiffs’ lawyers showed how public disclosure would hurt her proprietary or business interests. Of course, if Zambelli-Weiner had been dishonest in carrying out the Zofran study, as reflected in study deviations from its protocol, her professional credibility and her business of conducting such studies might well suffer. Zambelli-Weiner, however, was not prepared to affirm the antecedent of that hypothetical. In any event, the court found that whatever right Zambelli-Weiner might have enjoyed to avoid discovery evaporated with her previous dishonest representations to the MDL court.[7]

The Zofran Study Protocol

GSK sought production of the Zofran study protocol, which in theory contained the research plan for the Zofran study and the analyses the researchers intended to conduct. Zambelli-Weiner attempted to resist production on the specious theory that she had not published the protocol, but the court found this “non-publication” irrelevant to the claim of confidentiality. Most professional organizations, such as the International Society of Pharmacoepidemiology (“ISPE”), which ultimately published Zambelli-Weiner’s study, encourage the publication and sharing of study protocols.[8] Disclosure of protocols helps ensure the integrity of studies by allowing readers to assess whether the researchers have adhered to their study plan, or have engaged in ad hoc data dredging in search for a desired result.[9]

The Secret, Undisclosed Analyses

Perhaps even more egregious than withholding the study protocol was the refusal to disclose unpublished analyses comparing the rate of birth defects among children born to mothers who used Zofran with the birth defect rates of children with in utero exposure to other anti-emetic medications.  In ruling that Zambelli-Weiner must produce the unpublished analyses, the court expressed its skepticism over whether these analyses could ever have been confidential. Under ISPE guidelines, researchers must report findings that significantly affect public health, and the relative safety of Zofran is essential to its evaluation by regulators and prescribing physicians.

Not only was Zambelli-Weiner’s failure to include these analyses in her published article ethically problematic, but she apparently hid these analyses from the Pharmacovigilance Risk Assessment Committee (PRAC) of the European Medicines Agency, which specifically inquired of Zambelli-Weiner whether she had performed such analyses. As a result, the PRAC recommended a label change based upon Zambelli-Weiner’s failure to disclosure material information. Furthermore, the plaintiffs’ counsel represented they intended to oppose GSK’s citizen petition to the FDA, based upon the Zambelli-Weiner study. The apparently fraudulent non-disclosure of relevant analyses could not have been more fraught for public health significance. The MDL court found that the public health need trumped any (doubtful) claim to confidentiality.[10] Against the obvious public interest, Zambelli-Weiner offered no “compelling countervailing interest” in keeping her secret analyses confidential.

There were other aspects to the data-dredging rationale not discussed in the court’s order. Without seeing the secret analyses of other anti-emetics, readers were deprive of an important opportunity to assess actual and potential confounding in her study. Perhaps even more important, the statistical tools that Zambelli-Weiner used, including any measurements of p-values and confidence intervals, and any declarations of “statistical significance,” were rendered meaningless by her secret, undisclosed, multiple testing. As noted by the American Statistical Association (ASA) in its 2016 position statement, “4. Proper inference requires full reporting and transparency.”

The ASA explains that the proper inference from a p-value can be completely undermined by “multiple analyses” of study data, with selective reporting of sample statistics that have attractively low p-values, or cherry picking of suggestive study findings. The ASA points out that common practices of selective reporting compromises valid interpretation. Hence the correlative recommendation:

“Researchers should disclose the number of hypotheses explored during the study, all data collection decisions, all statistical analyses conducted and all p-values computed. Valid scientific conclusions based on p-values and related statistics cannot be drawn without at least knowing how many and which analyses were conducted, and how those analyses (including p-values) were selected for reporting.”[11]

The Draft Manuscript for the New England Journal of Medicine

The MDL court wasted little time and ink in dispatching Zambelli-Weiner’s claim of confidentiality for her draft New England Journal of Medicine manuscript. The court found that she failed to explain how any differences in content between this manuscript and the published version constituted “proprietary business information,” or how disclosure would cause her any actual prejudice.

Zambelli-Weiner’s Litigation Road Map

In a world where social justice warriors complain about organizations such as Exponent, for its litigation support of defense efforts, the revelation that Zambelli-Weiner was helping to quarterback the plaintiffs’ offense deserves greater recognition. Zambelli-Weiner’s litigation road map was clearly created to help Grant & Eisenhofer, P.A., the plaintiffs’ lawyers,, create a causation strategy (to which she would add her Zofran study). Such a document from a consulting expert witness is typically the sort of document that enjoys confidentiality and protection from litigation discovery. The MDL court, however, looked beyond Zambelli-Weiner’s role as a “consulting witness” to her involvement in designing and conducting research. The broader extent of her involvement in producing studies and communicating with regulators made her litigation “strategery” “almost certainly relevant to scientists and regulatory authorities” charged with evaluating her study.”[12]

Despite Zambelli-Weiner’s protestations that she had made a disclosure of conflict of interest, the MDL court found her disclosure anemic and the public interest in knowing the full extent of her involvement in advising plaintiffs’ counsel, long before the study was conducted, great.[13]

The legal media has been uncommonly quiet about the rulings on April Zambelli-Weiner, in the Zofran litigation. From the Union of Concerned Scientists, and other industry scolds such as David Egilman, David Michaels, and Carl Cranor – crickets. Meanwhile, while the appeal over the admissibility of her testimony is pending before the Pennsylvania Supreme Court,[14] Zambelli-Weiner continues to create an unenviable record in Zofran, Accutane,[15] Mirena,[16] and other litigations.
