Trials over time, by phase
- Observational
Top of scale: 1
Trials registered with a start date in each year, 1990 onward, stacked by phase (complete years only; the current partial year is in the table's notes). The table below lists the same counts, most recent years first.
| Year | Trials started |
|---|---|
| 2011 | 1 |
| 2004 | 1 |
| 2003 | 1 |
No forecast is made for this condition: it averages 0.0 trial starts a year over the five years to September, under the 5 a year the method needs.
Recruitment duration, a model prediction: none of the 3 trials evaluated at the 2026-10-09 snapshot is predicted and still running. Source: ClinicalTrials.gov / AACT (CTTI), public domain.
