The development phases
These are the standard phases of pharmaceutical development: preclinical work precedes testing in humans, phases I to III test the product in progressively larger groups, and phase IV follows it after authorisation. The percentage states how far the programme has declared itself along that path.
- Preclinical0–25%
- Phase I26–50%
- Phase II51–75%
- Phase III76–90%
- Phase IV91–100%
- The five phases indicate each programme's internal development status, from initial research through to market.
