BOSTON (

TheStreet

Sanofi-Aventis

(SNY) - Get Report

launched a $69-a-share hostile tender offer for

Next week, the scheduling of the muay thai bout between Sanofi's Chris Viehbacher and Genzyme's Henri Termeer. My money is on Viehbacher.

@adamfeuerstein's tweet of the week:

Somaxon Pharmaceuticals

( SOMX)

$SOMX -- 4 weeks since the Silenor launch... Guess how many scripts have been written? C'mon, guess...

The answer is... 99 Silenor scripts! Not 99 dozen scripts.

Just 99 scripts

in four weeks. Ouch. $SOMX making $VNDA's Fanapt look like a rocket.
