In Re: Diet Drugs Prod. Liab. Litig., No. 12-1180 (3d Cir. 2013)Annotate this Case
Between 1994 and 1997 Wyeth’s predecessor sold fenfluramine and dexfenfluramine, prescription weight loss drugs. After the drugs were linked to valvular heart disease and an FDA public health advisory, Wyeth withdrew the drugs from the market in 1997. Thousands of individuals filed suit; the cases were consolidated. In 1999, Wyeth entered into a Settlement Agreement; in 2000, the court certified the class, approved the Agreement, and retained jurisdiction. The Agreement enjoins class members from suing Wyeth for diet drug-related injuries, but allows class members to sue Wyeth if they can demonstrate that they developed PPH (a condition that deprives the lungs of oxygen) at a specified level through the use of the diet drugs. In 2011, Cauthen sued, alleging that she developed PPH. She produced a pulmonary consultation prepared by Fortin, a cardiologist. Because Cauthen’s report showed that lung capacity of less than 60 percent of predicted at rest, Wyeth sought to enjoin the state court lawsuit for failing to satisfy the precondition provided by the Agreement. Dr. Fortin asserted that comparing individual lung capacity with average capacity of persons having a similar demographic profile is not determinative in diagnosing PPH. The district court enjoined the suit. The Third Circuit affirmed.
