Sponsor delivery record (1)
Enrollment hit target: the share of this sponsor's lead-sponsored trials whose actual enrollment reached the planned enrollment. On time: the share whose actual primary completion date was no later than the planned date. Each share counts only trials where we observed an estimated figure before the actual one, and n is that number of trials. Below 5 trials the count is shown as a fraction, not a percentage.
| Enrollment | Timeline |
|---|---|
| 1 of 3 hit target (n=3) | 33% on time (n=6) |
