Shares of Vertex Pharmaceuticals Inc. skyrocketed following the release of a phase 3 clinical trial that showed a combination of two cystic fibrosis drugs it developed helped people with the deadly disease breathe more easily, raising hopes the treatment could be on the market by late next year. CEO Jeffrey Leiden said the encouraging study results mean the company is likely to file for approval of the treatment in the United States and Europe by the end of the year, and will seek priority review by regulators.
