Vertex Falls as Analyst Cuts Hep C Sales Estimate: Boston Mover

Vertex Pharmaceuticals Inc. fell the most in seven weeks after an analyst with Leerink Swann & Co. cut sales estimates for a hepatitis C pill made by the company that was approved by U.S. regulators last year.

Vertex’s Incivek, among the first new hepatitis C drugs to reach the market in almost a decade, may be eclipsed by new pill-only treatments with fewer side effects and shorter courses of treatment. Incivek is given with interferon, an injected medicine. Merck & Co.’s similar pill, Victrelis, was also approved last year.
