When did Urticaria Pigmentosa trials start? (5)
Shown in this order: most recent first, 1990 onwards. 2026 is partial: trials registered with a 2026 start date so far, not a full year.
Trials over time, by phase
- Phase 2
- Not applicable
- Observational
Top of scale: 2
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.
