Today’s case — In re Tepezza Mkt’g, Sales Pracs., & Prod. Liab. Litig., MDL No. 3079, 2025 WL 81338 (N.D. Ill. Nov. Jan. 10, 2025) – doesn’t really break new ground on the substantive law, in fact it is a split decision. But it comes from an unusual procedural posture worth pointing out.
The Tepezza MDL was created in June 2023 and shortly thereafter the court ruled on a pending motion to dismiss in a single case. The court denied the motion as to plaintiff’s pre-market design defect claims. We were not particularly fond of the ruling and said so here. It appears that since that time, the court decided to create a group of “bellwether discovery” cases. The idea is that motions to dismiss get teed up and ruled on in the 12 “bellwether discovery” cases to establish the scope of discovery. We can’t help but be intrigued with any process which has as a component setting boundaries on discovery. Realistically, particularized rulings on plaintiffs’ claims could lead to less discovery. For instance, certain time periods could be deemed out of bounds. Or, if design defect claims are dismissed, that might limit the amount of research and development discovery that is warranted. Furthermore, tethering the discovery to the claims of 12 actual plaintiffs, regardless of the rulings on the motions, could also be potentially helpful to defendants. Often, discovery against the manufacturer in an MDL tosses open the doors to the company at large because plaintiffs claim they are taking discovery for all plaintiffs, for all purposes, for all claims, for all times. Putting discovery in context, including the context of 12 individual plaintiffs, almost always inures to the benefit of the defense. For our readers who spend a significant time slogging it out with plaintiffs on discovery disputes, we’ll keep our eyes on whether this discovery bellwether generates any useful precedent or tips going forward.
Now to turn to the substance. Plaintiffs in the Tepezza MDL allege “hearing loss and/or tinnitus” from the use of an FDA-approved prescription biologic for thyroid eye disease. Defendants challenged the bellwether plaintiffs’ failure to warn, design defect, and fraudulent misrepresentation. They won one, lost one, and split one.
On failure to warn, defendant argued that the claims were preempted because plaintiffs failed to adequately plead that defendant could have used the CBE process to change its label before September 2022—after plaintiffs had stopped their treatment. First, we should point out that while Tepezza is a biologic, the CBE regulation is substantively identical to that for prescription drugs. So, to avoid preemption, a plaintiff “must plead that the manufacturer had newly acquired information that showed a causal association between the drug and an effect that warranted a new or stronger warning, precaution, or adverse reaction in the label.” In re Tepezza, at *4. In that situation, the manufacturer does not need FDA approval to change its label; therefore, no preemption. Here, plaintiffs cited to a clinical study that came out in September 2020 that showed a sufficient increase in the incidence rate to arguably satisfy the CBE requirements. Id. at *5. Defendant argued that the study could not form the basis for a CBE label change because it was not a “clinical trial,” but the court found “criticism of the quality of [the study] . goes to the sufficiency of the evidence proving the allegations, not the sufficiency of the allegations. Since all of the bellwether plaintiffs used Tepezza after September 2020, their failure to warn claims were not preempted at the pleadings stage.
On design defect, plaintiffs failed to meet the TwIqbal pleading standard. In fact, plaintiff only made boilerplate allegations offering no facts and giving the court no basis from which to infer what aspect of the product makes it defective. Plaintiffs tried to argue that under at least Florida and New York law, they didn’t need to allege a design defect before discovery because they do not have the technical information required to do so. However, plaintiffs relied on cases in which the complaints contained many more factual details than they allege here. Plaintiffs don’t have to prove a specific defect in their complaint, but they have “to do more than assert the conclusion that Tepezza is defective.” Id. at *7. Plaintiffs’ allegations about dosage were not supported by the evidence they pointed to in the complaint. Moreover, simply alleging that dose is too high does not satisfy the need to allege an alternative design. Id. at *9. With design defect dismissed, plaintiffs asked for permission to amend their complaints—long after the MDL deadline to do so. They claimed that they had new evidence that defendant was conducting a clinical trial on a new delivery method. Not only was the study announced months before the pleadings deadline, but it was also not scheduled to be completed until 2026 and had no safety or efficacy results as of yet. The ”mere initiation of a study” does not “plausibly suggest” a defect in the current delivery method or indicate that the method being studied will turn out to be safer or more efficacious. Plaintiff did not offer good grounds for their motion to amend, and it was denied.
That left only plaintiffs’ fraudulent misrepresentation claim which was essentially the same as their failure to warn claim. Plaintiffs’ fraud claim was based on two allegations—that defendant overstated the efficacy of the biologic and defendant misstated the incidence rate. Applying Rule 9’s heightened pleading requirement for fraud, the court found both allegations were lacking. The first was simply not supported by any factual allegations (“plaintiffs’ allegations regarding efficacy are highly generalized”). Id. at *10. As to the second, plaintiffs had conflicting allegations, including statements that the incidence rate on the label was accurate. “So, Plaintiffs’ assertion of falsity is not well pled.” Id. at *11. While the fraud itself was not sufficiently pleaded, the court found plaintiffs’ fraud damages need not be pleaded with particularity. And defendants raised one more issue—that because the fraud claim is based on the FDA-approved label, it is actually a preempted fraud-on-the-FDA claim. Here the court concluded it had insufficient information on which to base a decision. Because the fraud claim is substantively the same as the failure to warn claim, a ruling on Buckman preemption would not change the scope of discovery, and therefore the court deferred the issue. So, on fraudulent misrepresentation the final ruling is defendant’s motion to dismiss is granted in part (fraud allegations), denied in part (damages); and continued in part. Except as to the Pennsylvania plaintiff because Pennsylvania does not recognize fraud claims based on a failure to warn theory. Her claim was dismissed with prejudice.
Like we said, a 50/50 split decision on the claims—but a possible case to watch for discovery.
