FDA drug-approval catalyst change stream for US-listed biotechs: every state change of every catalyst we track — each PDUFA date as it is set, extended and resolved — with the real outcome (approval, or CRL/rejection), the SEC filing quote and its EDGAR source. A superset of the upcoming calendar, as a since-cursor delta feed. Date accuracy AND our coverage of the FDA universe are both published free and unflattered at GET /v1/accuracy — audit before you pay. Priced flat per request.
