ZURICH, Dec 21 (Reuters) - Here are some of the main factors that may affect Swiss stocks on Wednesday:
The U.S. Food and Drug Administration (FDA) has extended until March 28 the date for reviewing the application for multiple sclerosis drug Ocrevus. "The extension is the result of the submission of additional data by Roche regarding the commercial manufacturing process of Ocrevus, which required additional time for FDA review. The extension is not related to the efficacy or safety of Ocrevus," Roche said.
Talks between Actelion and Sanofi are making progress, despite investors' fears that the Swiss biotech firm's chief executive and founder might not want to sell, a person with direct knowledge of the situation said on Tuesday.
The source said Actelion had now reached a point where the company needed to sign a deal and it could not call off negotiations with the French drugmaker without triggering an investor rebellion demanding the overthrow of its board.
