When did Paralysis trials start? (34)

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. 5 trials are registered to start in 2027 or later, and not listed here.

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.

2024 106

Forecast of the full-year count, planned starts included, not rows of this table: about 120 trials starting in 2026 and about 110 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 13 percent and ran about 12 percent low against the count later registered; forecasts made before the year began were off by about 19 percent and ran about 17 percent low against the count later registered, and had about the same error as repeating last year's count. 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 135 trials still running at the 2026-10-09 snapshot; registered median of 20 months across 819 trials with a primary completion typed Actual. Source: ClinicalTrials.gov / AACT (CTTI), public domain.

Which lead sponsors run the most Paralysis 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.
