Medivation board rejects Sanofi's $9.3 billion takeover offer

(Reuters) - Medivation Inc said on Friday its board rejected an unsolicited $9.3 billion (6.35 billion pounds) takeover proposal from Sanofi SA , saying the offer undervalued the company and its pipeline of oncology drugs. The French drugmaker went public with its $52.50 per share cash offer on Thursday. Medivation's shares were trading at $56.41 before market open on Friday. "Our Board strongly believes that Medivation's business plan will deliver value to our stockholders that is far superior to Sanofi's offer and unanimously rejects your proposal," Medivation said in statement.
