The generic drug industry suffered a disappointment when the 1st Circuit recently held federal law did not preempt state tort law in design defect cases. The 2011 U.S. Supreme Court decision in PLIVA, Inc. v. Mensing held that state law tort claims based on defective warning labels are preempted because generic drug manufacturers must use labels that are the “same” as the brand-name drugs’ labels. Since PLIVA v. Mensing was decided, generic companies have argued this reasoning should extend preemption to design defect claims because generic companies must use the same design, just as they must use the same labels. Several district courts had endorsed this reasoning in other circuits. The 1st Circuit held in Bartlett v. Mutual Pharmaceutical Co., Inc., however, that PLIVA did not extend to design-defect claims against Mutual Pharmaceutical Company. On July 31, Mutual filed a writ of certiorari with the U.S. Supreme Court, asking for summary reversal of Bartlett because the “sameness” rationale supporting preemption in Mensing should also apply to the design of the drug product.
Mutual argues in its writ that the sameness mandate of the Hatch-Waxman Act of 1984 precludes drug manufacturers “from unilaterally altering either the label or design of their generic drug products”; that there is no rationale to distinguish failure-to-warn and design-defect claims, and thus both types of claims are preempted under Mensing. The principle underlying the Mensing opinion—that Congress intended the Hatch-Waxman Act to give the public greater access to less expensive generic drugs—should apply equally to design-defect claims. Mutual points out that the brand-name drug company is obligated to conduct “extensive and costly clinical trials” as part of its New Drug Application (NDA), but Hatch-Waxman created a process by which generic companies need only submit an Abbreviated New Drug Application (ANDA) “that simply demonstrates the product’s chemical and biological equivalence to a previously approved drug product.” The Supreme Court in Mensing relied on these differences, stating: “It is beyond dispute that the federal statutes and regulations that apply to brand-name drug manufacturers are meaningfully different than those that apply to generic drug manufacturers. Indeed, it is the special, and different, regulation of generic drugs that allowed the generic drug market to expand, bringing more drugs more quickly and cheaply to the public.”
