Free v. Ethicon, Inc. et al Doc. 124 IN THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF WEST VIRGINIA CHARLESTON DIVISION IN RE: ETHICON INC. PELVIC REPAIR SYSTEMS PRODUCT LIABILITY LITIGATION MDL No. 2327 ______________________________________________________________________________ THIS DOCUMENT RELATES TO: Cases Identified in the Exhibit Attached Hereto MEMORANDUM OPINION AND ORDER (Daubert Motion re: Salil Khandwala, M.D.) Pending before the court is the Motion to Exclude or Limit the Opinions and Testimony of Dr. Salil Khandwala, M.D. [ECF No. 2003] filed by the plaintiffs. The Motion is now ripe for consideration because briefing is complete. I. Background This case resides in one of seven MDLs assigned to me by the Judicial Panel on Multidistrict Litigation concerning the use of transvaginal surgical mesh to treat pelvic organ prolapse (“POP”) and stress urinary incontinence (“SUI”). In the seven MDLs, there are more than 75,000 cases currently pending, approximately 30,000 of which are in this MDL, which involves defendants Johnson & Johnson and Ethicon, Inc. (collectively “Ethicon”), among others. In this MDL, the court’s tasks include “resolv[ing] pretrial issues in a timely and expeditious manner” and “resolv[ing] important evidentiary disputes.” Barbara J. Rothstein & Catherine R. Borden, Fed. Judicial Ctr., Managing Multidistrict Dockets.Justia.com Litigation in Products Liability Cases 3 (2011). To handle motions to exclude or to limit expert testimony pursuant to Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993), the court developed a specific procedure. In Pretrial Order (“PTO”) No. 217, the court instructed the parties to file only one Daubert motion per challenged expert, to file each motion in the main MDL—as opposed to the individual member cases—and to identify which cases would be affected by the motion. PTO No. 217, at 4.1 II. Preliminary Matters Before plunging into the heart of the Motion, a few preliminary matters need to be addressed. I am compelled to comment on the parties’ misuse of my previous Daubert rulings on several of the experts offered in this case. See generally Sanchez v. Bos. Sci. Corp., No. 2:12-cv-05762, 2014 WL 4851989 (S.D. W. Va. Sept. 29, 2014); Tyree v. Bos. Sci. Corp., 54 F. Supp. 3d 501 (S.D. W. Va. 2014); Eghnayem v. Bos. Sci. Corp., 57 F. Supp. 3d 658 (S.D. W. Va. 2014). The parties have, for the most part, structured their Daubert arguments as a response to these prior rulings, rather than an autonomous challenge to or defense of expert testimony based on its reliability and relevance. In other words, the parties have comparatively examined expert testimony and have largely overlooked Daubert’s core considerations for assessing expert 1 The plaintiffs identified the Wave 1 cases affected by this Motion in their attached Exhibit A [ECF No. 2003-1], which the court has attached to this Memorandum Opinion and Order. At the time of transfer or remand, the parties will be required to designate relevant pleadings from MDL 2327, including the motion, supporting memorandum, response, reply, and exhibits referenced herein. 2 testimony. Although I recognize the tendency of my prior evidentiary determinations to influence subsequent motions practice, counsels’ expectations that I align with these previous rulings when faced with a different record are misplaced, especially when an expert has issued new reports and given additional deposition testimony. Mindful of my role as gatekeeper for the admission of expert testimony, as well as my duty to “respect[ ] the individuality” of each MDL case, see In re Phenylpropanolamine Prods. Liab. Litig., 460 F.3d 1217, 1231 (9th Cir. 2006), I refuse to credit Daubert arguments that simply react to the court’s rulings in Sanchez and its progeny. Indeed, I feel bound by these earlier cases only to the extent that the expert testimony and Daubert objections presented to the court then are identical to those presented now. Otherwise, I assess the parties’ Daubert arguments anew. That is, in light of the particular expert testimony and objections currently before me, I assess “whether the reasoning or methodology underlying the testimony is scientifically valid” and “whether that reasoning or methodology properly can be applied to the facts in issue.” Daubert, 509 U.S. at 592–93. Any departure from Sanchez, Eghnayem, or Tyree does not constitute a “reversal” of these decisions and is instead the expected result of the parties’ submission of updated expert reports and new objections to the expert testimony contained therein. Finally, I have attempted to resolve all possible disputes before transfer or remand, including those related to the admissibility of expert testimony pursuant to Daubert. Nevertheless, in some instances I face Daubert challenges where my interest in accuracy counsels reserving ruling until the reliability of the expert 3 testimony may be evaluated at trial. At trial, the expert testimony will be tested by precise questions asked and answered. The alternative of live Daubert hearings is impossible before transfer or remand because of the numerosity of such motions in these seven related MDLs. As these MDLs have grown and the expert testimony has multiplied, I have become convinced that the critical gatekeeping function permitting or denying expert testimony on decisive issues in these cases is best made with a live expert on the witness stand subject to vigorous examination. In the course of examining a multitude of these very similar cases involving the same fields of expertise, I have faced irreconcilably divergent expert testimony offered by witnesses with impeccable credentials, suggesting, to me, an unreasonable risk of unreliability. The danger—and to my jaded eye, the near certainty—of the admission of “junk science” looms large in this mass litigation. The parties regularly present out-of-context statements, after-the-fact rationalizations of expert testimony, and incomplete deposition transcripts. This, combined with the above-described practice of recycling expert testimony, objections, and the court’s prior rulings, creates the perfect storm of obfuscation. Where further clarity is necessary, I believe it can only be achieved through live witness testimony— not briefing—and I will therefore reserve ruling until the expert testimony can be evaluated firsthand. III. Legal Standard By now, the parties should be intimately familiar with Rule 702 of the Federal Rules of Evidence and Daubert, so the court will not linger for long on these 4 standards. Expert testimony is admissible if the expert is qualified and if his or her expert testimony is reliable and relevant. Fed. R. Evid. 702; see also Daubert, 509 U.S. at 597. An expert may be qualified to offer expert testimony based on his or her “knowledge, skill, experience, training, or education.” Fed. R. Evid. 702. Reliability may turn on the consideration of several factors: (1) whether a theory or technique can be or has been tested; (2) whether it has been subjected to peer review and publication; (3) whether a technique has a high known or potential rate of error and whether there are standards controlling its operation; and (4) whether the theory or technique enjoys general acceptance within a relevant scientific community. Cooper v. Smith & Nephew, Inc., 259 F.3d 194, 199 (4th Cir. 2001) (citing Daubert, 509 U.S. at 592–94). But these factors are neither necessary to nor determinative of reliability in all cases; the inquiry is flexible and puts “principles and methodology” above conclusions and outcomes. Daubert, 509 U.S. at 595; see also Kumho Tire Co. v. Carmichael, 525 U.S. 137, 141, 150 (1999). Finally, and simply, relevance turns on whether the expert testimony relates to any issues in the case. See, e.g., Daubert, 509 U.S. at 591–92 (discussing relevance and helpfulness). At bottom, the court has broad discretion to determine whether expert testimony should be admitted or excluded. Cooper, 259 F.3d at 200. IV. Discussion Dr. Salil Khandwala is board-certified in obstetrics, gynecology, and female pelvic medicine and reconstructive surgery. 5 a. Safety and Efficacy The plaintiffs challenge the reliability of Dr. Khandwala’s expert testimony by criticizing the studies he chose to compare, opining he should have adjusted his criteria, noting his failure to account for varying definitions of “success,” claiming he focuses on objective outcomes over subjective outcomes, and pointing out his failure to publish his own study. At bottom, the plaintiffs have not sufficiently supported their arguments or credibly called into question the reliability of this expert testimony. The plaintiffs are free to raise their concerns on cross-examination, but their Motion is DENIED on this point. b. Mesh Properties The plaintiffs also seek exclusion of Dr. Khandwala’s testimony on biomaterials, biocompatibility, and foreign body response because he has “conceded” that he is not a biomaterials expert. Such concessions are not dispositive, particularly when taken out of context. Dr. Khandwala is a board-certified urogynecologist with a subspecialty in female pelvic medicine and reconstructive surgery. He has used polypropylene mesh in more than 1,000 SUI procedures and over 800 POP procedures. This extensive clinical experience qualifies Dr. Khandwala to opine on mesh’s reaction to and effect on the human body from a clinical perspective. The plaintiffs’ Motion is DENIED on this matter. The plaintiffs also challenge the reliability of Dr. Khandwala’s opinions on degradation and contraction. Ethicon acknowledges that Dr. Khandwala’s expert report contains no degradation opinion and represents that he will not offer 6 degradation opinions at trial. The plaintiffs’ Motion as to degradation is DENIED as moot. As to contraction, Dr. Khandwala’s opinion is supported by “extensive clinical experience and his analysis of the scientific literature.” Resp. 9 [ECF No. 2175]. In the abstract, these are reliable bases on which to form an expert opinion. See Kumho, 526 U.S. at 156 (“[N]o one denies that an expert might draw a conclusion from a set of observations based on extensive and specialized experience.”). However, the court is unable to judge the reliability of Dr. Khandwala’s observations without more information about his methodology. See Fed. R. Evid. 702 advisory committee’s note to 2000 amendment (“If the witness is relying solely or primarily on experience, then the witness must explain how that experience leads to the conclusion reached, why that experience is a sufficient basis for the opinion, and how that experience is reliably applied to the facts.”). I am without sufficient information at this time to draw the fine line between reliable and unreliable expert testimony based primarily on a doctor’s clinical experience not observing something. Accordingly, I RESERVE ruling until further testimony may be offered and evaluated firsthand at trial. The plaintiffs also seek to exclude Dr. Khandwala’s testimony on mesh porosity and stiffness, though on what grounds is unclear. To the extent they are challenging Dr. Khandwala’s qualifications, the Motion is DENIED for the reasons discussed above on biomaterials. To the extent they are challenging reliability, I RESERVE ruling for the reasons laid out above related to mesh contracture. c. Warnings 7 Ethicon states that Dr. Khandwala will not testify at trial regarding the adequacy of the relevant Instructions for Use. Accordingly, the plaintiffs’ Motion is DENIED as moot as to this matter. V. Recurring Issues Many of the Daubert motions filed in this MDL raise the same or similar objections. One particular issue has been a staple in this litigation, so I find it best to discuss it in connection with every expert. A number of the Daubert motions seek to exclude FDA testimony and other regulatory or industry standards testimony. To the extent this Motion raises these issues it is GRANTED in part and RESERVED in part as described below. I have repeatedly excluded evidence regarding the FDA’s section 510(k) clearance process in these MDLs, and will continue to do so in these cases, a position that has been affirmed by the Fourth Circuit. In re C. R. Bard, Inc., 81 F.3d 913, 921–23 (4th Cir. 2016) (upholding the determination that the probative value of evidence related to section 510(k) was substantially outweighed by its possible prejudicial impact under Rule 403). Because the section 510(k) clearance process does not speak directly to safety and efficacy, it is of negligible probative value. See In re C. R. Bard, 81 F.3d at 920 (“[T]he clear weight of persuasive and controlling authority favors a finding that the 510(k) procedure is of little or no evidentiary value.”). Delving into complex and lengthy testimony about regulatory compliance could inflate the perceived importance of compliance and lead jurors “to erroneously 8 conclude that regulatory compliance proved safety.” Id. at 922. Accordingly, expert testimony related to the section 510(k) process, including subsequent enforcement actions and discussion of the information Ethicon did or did not submit in its section 510(k) application, is EXCLUDED. For the same reasons, opinions about Ethicon’s compliance with or violation of the FDA’s labeling and adverse event reporting regulations are EXCLUDED. In addition to representing inappropriate legal conclusions, such testimony is not helpful to the jury in determining the facts at issue in these cases and runs the risk of misleading the jury and confusing the issues. Insofar as this Motion challenges the FDA-related testimony discussed here, the Motion is GRANTED. A number of experts also seek to opine on Ethicon’s compliance with design control and risk management standards. Some of this testimony involves the FDA’s quality systems regulations, and some—likely in an attempt to sidestep my anticipated prohibition on FDA testimony—involve foreign regulations and international standards. I find all of this proposed testimony of dubious relevance. Although these standards relate to how a manufacturer should structure and document risk assessment, the standards do not appear to mandate any particular design feature or prescribe the actual balance that must be struck in weighing a product’s risk and utility. Nor is it clear that the European and other international standards discussed had any bearing on the U.S. medical device industry when the device in question was being designed. Nevertheless, because the nuances of products liability law vary by state, I will 9 refrain from issuing a blanket exclusion on design process and control standards testimony, whether rooted in the FDA or otherwise. Each standard must be assessed for its applicability to the safety questions at issue in this litigation, consistent with state law. I am without sufficient information to make these findings at this time. Accordingly, I RESERVE ruling on such matters until a hearing, where the trial judge will have additional context to carefully evaluate the relevance and potential prejudicial impact of specific testimony. Similarly, I doubt the relevance of testimony on the adequacy of Ethicon’s clinical testing and research, physician outreach, or particular product development procedures and assessments otherwise not encompassed by the above discussion. Again, such matters seem to say very little about the state of the product itself (i.e., whether or not it was defective) when it went on the market. But because the scope of relevant testimony may vary according to differences in state products liability law, I RESERVE ruling on such matters until they may be evaluated in proper context at a hearing before the trial court before or at trial. Additional—and more broad—matters also warrant mention. While some of these concerns may not apply to this particular expert, these concerns are raised so frequently that they are worth discussing here. First, many of the motions seek to exclude state-of-mind and legal-conclusion expert testimony. Throughout these MDLs, the court has prohibited the parties from using experts to usurp the jury’s fact-finding function by allowing testimony of this type, and I do the same here. E.g., In re C. R. Bard, Inc., 948 F. Supp. 2d 589, 611 10 (S.D. W. Va. 2013); see also, e.g., United States v. McIver, 470 F.3d 550, 562 (4th Cir. 2006) (“[O]pinion testimony that states a legal standard or draws a legal conclusion by applying law to the facts is generally inadmissible.”); In re Rezulin Prods. Liab. Litig., 309 F. Supp. 2d 531, 546 (S.D.N.Y. 2004) (“Inferences about the intent and motive of parties or others lie outside the bounds of expert testimony.”). Additionally, an expert may not offer expert testimony using “legal terms of art,” such as “defective,” “unreasonably dangerous,” or “proximate cause.” See Perez v. Townsend Eng’g Co., 562 F. Supp. 2d 647, 652 (M.D. Pa. 2008). Second, and on a related note, many of the motions seek to prohibit an expert from parroting facts found in corporate documents and the like. I caution the parties against introducing corporate evidence through expert witnesses. Although an expert may testify about his or her review of internal corporate documents solely for the purpose of explaining the basis for his or her expert opinions—assuming the expert opinions are otherwise admissible—he or she may not offer testimony that is solely a conduit for corporate information. Third, many of the motions also ask the court to require an expert to offer testimony consistent with that expert’s deposition or report or the like. The court will not force an expert to testify one way or another. To the extent an expert offers inconsistent testimony, the matter is more appropriately handled via crossexamination or impeachment as appropriate and as provided by the Federal Rules of Evidence. Fourth, in these Daubert motions, the parties have addressed tertiary 11 evidentiary matters like whether certain statements should be excluded as hearsay. The court will not exclude an expert simply because a statement he or she discussed may constitute hearsay. Cf. Daubert, 509 U.S. at 595. Hearsay objections are more appropriately raised at trial. Finally, in some of the Daubert motions, without identifying the specific expert testimony to be excluded, the parties ask the court to prevent experts from offering testimony the expert is not qualified to offer. I will not make speculative or advisory rulings. I decline to exclude testimony where the party seeking exclusion does not provide specific content or context. VI. Conclusion The court DENIES in part, GRANTS in part, and RESERVES in part the Motion to Exclude or Limit the Opinions and Testimony of Dr. Salil Khandwala, M.D. [ECF No. 2003]. The court DIRECTS the Clerk to file a copy of this Memorandum Opinion and Order in 2:12-md-2327 and in the Ethicon Wave 1 cases identified in the Exhibit attached hereto.
