After plaintiff's son died of Hepatosplenic T-cell lymphoma (HSTCL), an exceedingly rare and aggressive form of cancer, they filed suit alleging negligence and strict liability concerning the manufacture and distribution of drugs used to treat inflammatory bowel disease (IBD). The Ninth Circuit reversed the grant of summary judgment to Teva, holding that the district court erred by excluding plaintiffs' causation experts' testimony. In this case, the district court looked too narrowly at each individual consideration under Daubert v. Merrell Dow Pharm., Inc., 509 U.S. 579, 589 (1993), without taking into account the broader picture of the experts' overall methodology. The district court improperly ignored the experts' experience, reliance on a variety of literature and studies, and review of the son's medical records and history, as well as the fundamental importance of differential diagnosis by experienced doctors treating troubled outpatients. Furthermore, the district court overemphasized the fact that the experts did not develop their opinions based on independent research and the experts did not cite epidemiological studies. The panel reversed the district court's grant of summary judgment to Teva in regard to the duty to warn claim because there was a genuine dispute of material fact as to whether the prescribing physician's conduct would have changed with warnings from Teva and GSK. The panel declined to affirm the district court on four alternative grounds and reversed the district court's denial of plaintiffs' motion for reconsideration. View "Wendell v.
