When did Glycogen Storage Disease Type V trials start? (9)
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 1
- Phase 2
- Not applicable
- Observational
Top of scale: 4
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 0.4 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 16 trials evaluated at the 2026-10-09 snapshot is predicted and still running. Source: ClinicalTrials.gov / AACT (CTTI), public domain.

Which lead sponsors run the most Glycogen Storage Disease Type V trials? (3)
Shown in this order: most trials first. Lead sponsors the registry classes as industry, NIH, US federal, other government or network. A hospital or university the registry files as government can appear here. Sponsors it classes as academic or other are shown on the full page, because that class cannot separate an institution from a named investigator.
