| Last year I panic-sold my biotech positions after missing two PDUFA dates in the same week. Both drugs got rejected. I was using a free tracker that hadn't been updated in months. So I looked at what's available: → BioPharmCatalyst: $30-50/month
→ Free alternatives: clunky UIs from 2010, outdated data, broken filters
→ Finviz/Yahoo: no catalyst-specific tracking I built CatalystAlert to fix this. What it tracks:
→ 985 biotech companies, 1714 drugs in pipeline
→ PDUFA dates, Phase 1/2/3 readouts, AdCom meetings
→ Data pulled daily from ClinicalTrials.gov, SEC EDGAR, FDA Stack: Next.js, Python data pipeline, daily automated scraping. No account required, no paywall, no "unlock premium to see this date." The core stays free. I'm prototyping V2 with ML-based approval probability predictions (trained on historical FDA decisions + trial endpoints) – that might have a paid tier eventually, but the calendar never will. Feedback I'd love:
1. Data sources I'm missing?
2. Filters or views that would save you time?
3. Anything broken or confusing? Thanks for checking it out. |
