On May 20, 2019, the Supreme Court of the United States issued a rare unanimous decision in Merck Sharp & Dohme Corp. v. Albrecht, et al., holding that judges, not juries, must decide whether state law failure-to-warn claims against brand-name drug manufacturers are preempted by the FDA’s labeling regulations. In so holding, the Court further clarified the preemption standard set forth in an earlier decision, Wyeth v. Levine, concluding that such claims are preempted where a drug manufacturer can show “that it fully informed the FDA of the justifications for the warning required by state law and that the FDA, in turn, informed the drug manufacturer that the FDA would not approve changing the drug’s label to include that warning.”
