Ninth Circuit Affirms Exclusion of Expert and Resulting Summary Judgment in In re: Incretin-Based Therapies MDL

Early last year, the In re: Incretin-Based Therapies MDL court held that the plaintiffs’ warnings claims were preempted, excluded plaintiffs’ general causation experts, and granted summary judgment to all defendants on dual preemption and causation grounds. In re: Incretin-Based Therapies Prods. Liab. Litig., 524 F. Supp. 3d 1007 (S.D. Cal. 2021). For context, that was the second time the defendants won summary judgment; the Ninth Circuit had reversed an earlier preemption victory in an opinion that predated the Supreme Court’s decision in Albrecht. In re Incretin-Based Therapies Prods. Liab. Litig., 721 F. App’x. 580 (9th Cir. 2017). Now, however, the Ninth Circuit has affirmed summary judgment as to one defendant (Novo Nordisk A/S (“Novo”)). In re: Incretin-Based Therapies Prod. Liab. Litig., 2022 WL 898595 (9th Cir. Mar. 28, 2022).
