BOSTON ( TheStreet) -- An early Christmas present for biotech investors: The first (overstuffed) FDA drug approval calendar of 2011.

For easy reference, I've organized this regulatory calendar in chronological order based on the drug approval decision date. I've also included information on pending FDA advisory panels. At the end of the calendar is a list of companies with potential regulatory milestones in 2011 based on expected but not yet completed drug approval filings.

In all, this calendar contains drug approval and regulatory milestone information on 34 drug and biotech stocks for 2011.
