Jan 27 (Reuters) - Sage Therapeutics SAGE.O said on
Monday that its board has unanimously rejected the takeover
offer it received from Biogen BIIB.O .
The company said Biogen's offer to buy all outstanding
shares of Sage that it does not already own for $7.22 apiece,
"significantly undervalues Sage and believes it is not in the
best interest of shareholders."
Biogen has a 10.2% stake in Sage Therapeutics.
Sage said it has initiated a process to explore
strategic alternatives, but has not set a timetable for the
review process.
