When did De Lange Syndrome trials start? (7)

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 2/3
  • Not applicable
  • Observational

Top of scale: 2

2010: 1 trials (Observational 1) 2016: 1 trials (Observational 1) 2018: 1 trials (Observational 1) 2023: 1 trials (Not applicable 1) 2024: 2 trials (Observational 1, Phase 2/3 1) 2025: 1 trials (Not applicable 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.

No forecast is made for this condition: it averages 0.8 trial starts a year over the five years to September, under the 5 a year the method needs.

Recruitment duration, a model prediction: 1 trial still running at the 2026-10-09 snapshot, fewer than the 5 needed for a median. Source: ClinicalTrials.gov / AACT (CTTI), public domain.
