> BiopharmaWatch is a biotech investing intelligence platform providing real-time FDA & PDUFA calendars, clinical-trial data, probability-of-approval scores, insider trading, hedge-fund holdings, M&A target scores, and market-moving catalysts for 2,000+ biotech and pharmaceutical stocks. Data is aggregated from primary regulatory sources and updated daily.

BiopharmaWatch helps biotech investors track drug-approval dates, regulatory events, clinical readouts, and company fundamentals. A free tier covers core data; full datasets and proprietary scores are available to subscribers.

## Data sources & methodology

Aggregated and structured from primary sources, updated daily:
- PDUFA dates and FDA decisions - company press releases and SEC filings (8-K); the FDA does not publish pending PDUFA dates
- Clinical trials - ClinicalTrials.gov (NCT records)
- Insider transactions & institutional holdings - SEC EDGAR (Form 4, 13F)
- Financials & prices - company 10-K/10-Q filings and market data

Proprietary models: **Probability of Approval (PoA)** - Bayesian, base-rate-adjusted estimate per drug/indication; **M&A Target Scores** - acquisition-likelihood across the biotech universe; **risk-adjusted NPV (rNPV)** per pipeline asset.
