In a research note partially titled "Something's Better Than Nothing," JPMorgan analyst Chris Schott says Friday night's FDA approval for nerve block is a "clear positive" for Pacira Pharmaceuticals. He notes that the Street broadly expected a Complete Response Letter for Exparel in this indication. While the approval does not include a broad nerve block label, it does allow Pacira to target 1M shoulder blocks performed annually, Schott tells investors. However, the Exparel label update also included several failed nerve block studies that should limit off label use of the drug, the analyst adds. He keeps a Neutral rating on Pacira.
