205 of the 306 trials are tagged with Dystonia itself; the rest are tagged with a narrower condition beneath it.
When did Dystonia trials start? (28)
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. 1 trial is registered to start in 2027 or later, and not listed here.

Top of scale: 18
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 |
|---|---|
| 2026 (partial year) | 9 |
| 2025 | 13 |
| 2024 | 18 |
| 2023 | 17 |
| 2022 | 8 |
| 2021 | 18 |
| 2020 | 9 |
| 2019 | 18 |
| 2018 | 11 |
| 2017 | 16 |
Showing 10 of 28 earlier years.
Forecast of the full-year count, planned starts included, not rows of this table: about 11 trials starting in 2026 and about 13 in 2027, the average of the 24 months through September, counted as registered and carried forward. The rows of this table count trials registered so far with a start date in the year, planned starts included; the forecast looks ahead to the count for the whole year, so it is not the same measure. In backtests on conditions of this size, forecasts made part-way through the year were typically off by about 28 percent and ran about 20 percent low against the count later registered; forecasts made before the year began were off by about 39 percent and ran about 37 percent low against the count later registered. These figures rest on a few years of history (target years from 2018 to 2025, varying by figure), place each condition as it is mapped today rather than as it was then, and score against a count for the newest year that was still being revised. Only condition series were scored.
Prediction, not a registry value: median of 36 months from start to primary completion across 22 trials still running at the 2026-10-09 snapshot; registered median of 28 months across 170 trials with a primary completion typed Actual. Source: ClinicalTrials.gov / AACT (CTTI), public domain.

Which lead sponsors run the most Dystonia trials? (5)
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.

| National Institute of Neurological Disorders and Stroke (NINDS) | 35 |
| Ipsen | 11 |
| Allergan | 9 |
| Fondation Ophtalmologique Adolphe de Rothschild | 5 |
| Institut National de la Santé Et de la Recherche Médicale, France | 4 |
