If orphan drugs and rare diseases were a theme of 2013's biotech bull market, then today's $700 million deal between Alnylam (ALNY 0.51%) and Sanofi (SNY 0.63%) is a sign it isn't slowing down anytime soon.

In this video, Motley Fool health-care analyst David Williamson discusses the specifics of the deals, what Sanofi is gaining, why the market loves Alnylam, and why 2015, with half a dozen proof-of-concept trials reporting, will be a big year for the stock.
