How the field has grown

New-trial starts peaked in 2021 (33 registered); 2025 saw 12. The right-hand chart shows median Phase 3 enrollment by start year — the number in parentheses is that year's Phase 3 trial count (24 in total), so single-trial years (and years with no Phase 3 starts) are obvious. Both are by trial start date; the current year is partial.
