It's true, we're not quite finished with 2008 just yet, but I've certainly started to plan for next year. For me, that begins with compiling a calendar of meaningful clinical trials and data-related events expected to take place in the new year.

So I've put together a list, in alphabetical order, of biotech and drug companies with important (stock-moving) clinical trials expected to have data available in the first six months of 2009. I use a list like this for planning and research purposes, so I'm prepared in advance for when these data are released. Thanks to BioMedTracker, a service of Sagient Research, for assisting with the research for this list.

A prepared biotech investor is a richer biotech investor. Perhaps I should have that printed on T-shirts
