From October 2010 to February 2011, biotech Clinical Data's stock doubled, mostly thanks to FDA approval of its novel antidepressant. But also pushing the stock up -- and making it likely to perhaps double again -- is speculation that a Big Pharma will buy Clinical Data.

ZIOPHARM has enticed several major institutional investors to put their money in it. And it has an all-star group of cancer scientists joining its committee to design Phase 3 clinical trials for its chief product, Zymafos, a cancer treatment.
