Knight v. Boehringer Ingelheim Pharmaceuticals, Inc., No. 19-1636 (4th Cir. 2021)Annotate this Case
After Boehringer developed a drug called Pradaxa to help reduce the risk of stroke, the FDA approved the drug and its label. Betty Knight suffered complications from taking the drug and eventually died. Betty's children filed suit against Boehringer asserting a variety of state-law claims alleging Boehringer failed to adequately warn about the risks associated with taking Pradaxa. Boehringer argued that federal law preempted the claims, the district court agreed with plaintiffs, and then the jury returned a mixed verdict. Boehringer appealed, claiming that plaintiffs' fraud claim based on the physician label was preempted.
The Fourth Circuit reversed the district court's order denying Boehringer's post-trial motion for judgment as a matter of law. The court held that there is no bright-line, one-size-fits-all line marking the moment when an analysis reveals new information. A careful review of the record is needed to determine whether a conclusion has been reached. Applying careful review here, the court concluded that Boehringer did not have "newly acquired information" regarding an optimal Pradaxa blood concentration level which would have warranted a unilateral change to the physician label. Therefore, the state-law fraud claim is preempted.
