FDA Calendar

PDUFA dates and FDA Panel Review dates are very important catalysts because they are ‘make or break events’ for biotech stocks.

The goal date set by the FDA for announcing its decision on a company’s New Drug Application/ Biologics License Application/sBLA/sNDA after reviewing the applications is known as the PDUFA date.

Usually, the stocks experience a run-up going into the scheduled FDA Approval decision/FDA Panel review events. So, having prior knowledge of the key dates goes a long way toward maximizing profit or minimizing loss while investing in the volatile biotech stocks.

Listed below are large cap, mid cap and small cap stocks with pending regulatory catalysts.
