When did Paramyxoviridae Infections trials start? (32)
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.

Top of scale: 40
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) | 21 |
| 2025 | 31 |
| 2024 | 40 |
| 2023 | 39 |
| 2022 | 27 |

| 2018 | 19 |

Showing 10 of 32 earlier years.
Forecast of the full-year count, planned starts included, not rows of this table: about 28 trials starting in 2026 and about 31 in 2027, the average of the 24 months through September, counted as registered and carried forward, with about 0.7 times the starts already registered for the rest of 2026 added. 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 15 percent and ran about 1 percent high against the count later registered; forecasts made before the year began were off by about 26 percent and ran about 20 percent low against the count later registered. The part-way figures are from forecasts that used a multiple fitted only on earlier years. 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 28 months from start to primary completion across 31 trials still running at the 2026-10-09 snapshot; registered median of 12 months across 333 trials with a primary completion typed Actual. Source: ClinicalTrials.gov / AACT (CTTI), public domain.

Which lead sponsors run the most Paramyxoviridae Infections trials? (12)
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.
