Biotech stocks with key binary events/catalysts - FDA Approval/PDUFA dates, Advisory Committee and Phase 2 & 3 trial data releases dates are noted. Phase 1 catalysts for small-cap companies only are listed.

Refer to the FDA Calendar Glossary for a list of terms used in the FDA Decision Calendar and the Biotech Historical Catalyst Calendar for completed biotech stock catalysts.

NOTE: LARGE CAP CATALYSTS - generally only Phase 3 catalysts noted in company presentations and/or earnings releases are shown. Only NASDAQ and NYSE stocks are covered. Stocks listed on PINK/OTC exchanges are not covered.

The dates shown are provided by companies. A regulatory event, for example a PDUFA date or Advisory Committee Meeting, will be issued with an exact date by the FDA. However, most clinical release dates (i.e. Phase 1/2/3) are provided in a range format by companies (e.g, mid-2021 or 4Q 2021). Exact dates for clinical data releases are only rarely issued.
