Final yr, the federal court docket determination to exclude plaintiffs’ normal causation professional within the In re: Onglyza and Kombiglyze XR Merchandise Legal responsibility Litigation, MDL 2809 (E.D. Ken.),took a spot in our high ten better of 2022 (unique put up on that call right here).  And not using a normal causation professional, it’s not shocking that abstract judgement adopted shortly after.   In re Onglyza and Kombiglyze Prods Liab. Litigation, 2022 WL 3050665 (E.D. Ky. Aug. 2, 2022) (mentioned right here).  What we’ve not mentioned is the parallel litigation pending in state court docket in California.  Till immediately.

13 circumstances had been coordinated in California and the California choose additional coordinated with the MDL choose, together with conducting a joint Rule 702/Sargon listening to.  After which, the California court docket reached the identical conclusion because the federal court docket – plaintiffs’ normal causation professional’s opinion was excluded as a result of it did “not include a dependable methodology for weighing the proof however a shifting results-based methodology that fails to logically and constantly weigh all of the related proof.”  Onglyza Merchandise Circumstances, — Cal.Rptr.3d –, 2023 WL 3001055 (Cal. App. Apr. 19, 2023).  Once more, the subsequent step was abstract judgment based mostly on a scarcity of professional proof on normal causation.  Now, the California trial court docket determination, each as to exclusion and abstract judgment, has been affirmed by the appellate court docket.

The medication at situation are in school used to deal with diabetes.  Plaintiffs allege that the drug causes coronary heart failure and associated cardiac circumstances.  On the request of the FDA, producers carried out a cardiovascular outcomes research, a randomized managed trial (“RCT”) with a number of cardiac endpoints.  The results of the trial was that there was no statistically vital distinction between the drug and placebo for any major endpoint (cardiac demise, non-fatal coronary heart assault, non-fatal stroke) or secondary endpoint aside from hospitalization as a consequence of coronary heart failure.  Id. at *1.  Following the cardiac trial, the authors of the research defined that coronary heart failure discovering was “sudden and needs to be thought-about throughout the context of a number of testing that will have resulted in a false constructive outcome.”  Id.  The authors cautioned that the result relating to hospitalization for coronary heart failure warranted additional investigation.  Id.  Additional research was carried out within the type of observational research and meta-analyses, none of which discovered an affiliation between the drug and coronary heart failure.  Id

Plaintiffs proffered two consultants, a heart specialist who opined, based mostly on the findings of the RCT and animal research, that the drug was able to inflicting coronary heart failure; and a biostatistician.  Plaintiffs argued that the trial court docket overstepped in excluding the heart specialist’s opinion as a result of the legislation permits the professional to put extra weight on sure proof, just like the RCT, and fewer weight on different proof, like the whole lot else.  Id. at *5.  It might be one factor to put extra weight on an RCT, it’s one other to conclude that “the discovering from [the RCT] alone confirmed a causal hyperlink between [the drug] and coronary heart failure.”  Id.   This conclusion is especially flawed when the authors of the RCT concluded that the guts failure final result “must be confirmed in different ongoing research.”  A discovering plaintiff’s professional agreed with.

A trial court docket doesn’t abuse its discretion in excluding professional testimony on normal causation when the professional’s opinion relies on a single research that gives no cheap foundation for the opinion provided.

Id. at *6.

Plaintiffs’ subsequent argument was that their professional reliably carried out the Bradford Hill evaluation regardless of the trial court docket’s discovering that the professional misapplied six of the 9 Bradford Hill components.  For instance, one issue is “power of affiliation.”  The relative threat for hospitalization for elevated coronary heart failure was 1.27, however plaintiffs’ professional “couldn’t say whether or not 1.27 was a robust affiliation,” with “robust” being too subjective for him.  Id.  The court docket considered this because the professional “refusing to have interaction with an element of the Bradford Hill evaluation on its phrases.”  Id.  One other issue is consistency – “when the identical discovering is proven in a number of research throughout completely different populations and settings.”  Plaintiffs’ professional, nonetheless, “disregarded inconsistent information from human research and relied on information from preclinical animal research,” to assist this issue.  However, on the listening to, plaintiff’s professional conceded he was not certified to interpret animal information, so as a substitute he switched his place arguing that the RCT alone confirmed consistency as a result of it examined 16,000 sufferers.  However the consistency issue requires an professional to see if completely different research utilizing completely different methodologies reached the identical conclusion.  Plaintiffs’ professional’s cherry-picking of information reveals the “unreliability of his shifting, results-based methodology.”  Id.  On the “analogy” issue, plaintiffs’ professional needed to concede that coronary heart failure research carried out of different medication in the identical class likewise discovered no affiliation.  So, as a substitute, he analogized the drug at situation to medication in a unique class of diabetes drugs the place a hyperlink to coronary heart failure had been discovered.  The trial court docket noticed by way of the ploy:  the one motive to analogize to a unique class of medicine was as a result of it “supported his final conclusion,” the place the information on the drug at situation and its class didn’t.  Id. at *7.    

For all of those causes, and extra, the appellate court docket decided the trial court docket was effectively inside its discretion in excluding plaintiffs’ professional based mostly on its reasoned conclusion that the professional’s opinion was “shifting and unsound.”  Id. at *8.    

Plaintiffs additionally tried to argue that abstract judgment was improper as a result of professional causation proof was not vital.  That flies immediately within the face of settled legislation that “in a private damage motion causation have to be confirmed inside an inexpensive medical likelihood based mostly upon competent professional testimony.”  Id. at *9.  Even when plaintiff had supplied any authority that complicated medical causation, akin to coronary heart failure, might be confirmed by way of non-expert proof, the non-expert proof plaintiffs relied on was inadequate to cross the abstract judgment threshold.  The drug’s up to date label that stated take into account the dangers earlier than utilizing to deal with sufferers at excessive threat for coronary heart failure.  The RCT authors’ assertion that the chance of coronary heart failure must be additional investigated.  FDA statements after the RCT that the drug might trigger or improve the chance of coronary heart failure.  All of those statements are based mostly solely on the outcomes of the RCT – which can’t assist causation for all the identical causes plaintiffs’ professional’s reliance on the RCT alone couldn’t.  [P]laintiffs can’t try to bypass the shortcomings of [the RCT] by pointing to different proof that merely depends on [the RCT’s] discovering.”  Id. at *11.

Lastly, the court docket didn’t abuse its discretion in denying plaintiffs’ request for extra time to designate a brand new professional.  Plaintiff selected to designate one causation professional, that was their strategic determination.  Asking for a do-over would prejudice defendants and tax the court docket’s sources as it could require extra professional discovery and one other Sargon listening to.  Abstract judgment was affirmed.
