BOSTON ( TheStreet) -- I've put together an updated calendar of meaningful clinical trials with results expected through the end of the current year. The biotech and drug companies included here are listed in alphabetical order. Unlike U.S. Food and Drug Administration drug approvals, which are more precisely timed, the release dates for data from clinical trials is a bit fuzzier, so the timelines here are culled from company guidance when possible. Successful biotech traders and investors understand the importance of staying one step ahead of stock-moving catalysts in the biotech sector. Use this clinical trial list as a companion to my recently published FDA drug approval calendar. This list was compiled using company reports and the BioMedTracker service from Sagient Research, a subscription-based tool for keeping track of biotech and drug catalysts. Read on for the list.
