(Nasdaq: CVTX) announcement that its Board of Directors has rejected Astellas’ proposal to acquire CV Therapeutics for $16 per share in cash. The Astellas proposal represents a premium of 41% to CV Therapeutics’ closing price on January 26, 2009, the last day of trading before the proposal was made public, and a 69% premium to CV Therapeutics’ 60-day average closing price prior to the public disclosure of the offer.
