March and June are the key months. March = ESTABLISH-2 results, but I believe options may expire before results posted. By June I'm looking for a European partner, NDA filing and initiation of pneumonia and bacteremia trials. Exciting 2013 for Trius. You can always throw Trius into the buyout conversation too.
Personally, I'm looking to sell some covered calls in March/April or June at the 7.50 or 10 strikes if I can get a nice premium. I think 10 strike makes you money and 7.50 strike may cut your short if everything goes as expected.
