Today’s case is a favorable prescription drug preemption decision making a key holding on newly acquired information and adverse event reporting. It is a one-off case involving the prescription drug Korlym which is used to treat Cushing’s Disease. Pietrantoni v. Corcept Therapeutics Inc., 2022 WL 16857262 (D. Mass. Nov. 10, 2022). Plaintiff’s claims break down into three categories—design defect, failure to warn, and failure to monitor. Plaintiff dismissed her design defect claims and the failure to monitor claims are based on fairly unique facts. So, the case boils down to failure to warn which itself had two sub-categories—failure to warn based on product labeling and failure to warn based on failure to report adverse events. One is dismissed and the other is delayed.
Korlym was approved by the FDA in 2012. During the approval process, the FDA conducted a Medical Review of the drug which included information about endometrial thickening and the related complications experienced by users. Id. at *6. Therefore, the warnings that were approved to accompany the drug included the risks of vaginal bleeding and endometrial changes. Id. (full warnings set out in opinion at *7). The label was revised in 2016, but there was no change to these warnings. Plaintiff was prescribed the drug in 2018 and used it for approximately 10 months. She experienced complications that led to an emergency surgical procedure and further complications to future fertility. Id. at *8.
The opinion contains a nice recitation of the history of prescription drug preemption – Wyeth v. Levine, PLIVA, Inc. v. Mensing, Mutual Pharmaceutical Company v. Bartlett, and Merck Sharp & Dohme Corp. v. Albrecht. These four cases makeup the “analytical framework” for prescription drug preemption. Wyeth and Mensing establish that preemption hinges on the availability of the Changes Being Effected (“CBE”) procedure. If a manufacturer can unilaterally change the label without prior FDA approval via the CBE procedure, a warning deficiency claim is not preempted. Albrecht clarified, however, that even where the CBE procedure is available, if the manufacturer can demonstrate by clear evidence that the FDA would not have approved the change, the claim is preempted.
