When did Cardiac Complexes, Premature trials start? (20)
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 1/2
- Phase 2
- Phase 3
- Phase 4
- Not applicable
- Observational
Top of scale: 12
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) | 5 |
| 2025 | 10 |
| 2024 | 12 |
| 2023 | 8 |

Showing 10 of 20 earlier years.
Forecast of the full-year count, planned starts included, not rows of this table: about 7 trials starting in 2026 and about 8 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 30 months from start to primary completion across 12 trials still running at the 2026-10-09 snapshot; registered median of 19 months across 55 trials with a primary completion typed Actual. Source: ClinicalTrials.gov / AACT (CTTI), public domain.
