A federal appeals court set aside a lower-court verdict against Sanofi and Regeneron Pharmaceuticals in their dispute with Amgen involving patents on Amgen’s cholesterol drug Repatha and lifted an injunction against the marketing of their rival drug Praluent.

The U.S. Court of Appeals for the Federal Circuit ordered a new trial in the case.
