When did Legionnaires' Disease trials start? (6)
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
- Observational
Top of scale: 1
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 |

No forecast is made for this condition: it averages 0.2 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 6 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 Legionnaires' Disease trials? (2)
Shown in this order: most trials first. Lead sponsors the registry classes as industry, NIH, US federal, other government or network.
