Condition (MeSH)
Toxoplasmosis
ClinicalTrials.gov lists 39 trials for Toxoplasmosis or a narrower condition beneath it. National Institute of Allergy and Infectious Diseases (NIAID) has the most among industry and government lead sponsors, with 7.
Search trials, drugs, companies and investigators, and follow each one to the others. Individual plan, $249/seat/mo. Card required.
Trials per phase
27 of the 39 trials are tagged with Toxoplasmosis itself; the rest are tagged with a narrower condition beneath it.
When did Toxoplasmosis trials start? (16)
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

- Phase 4
- Not applicable
- Observational
Top of scale: 4
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.

No forecast is made for this condition: it averages 2.0 trial starts a year over the five years to September, under the 5 a year the method needs.
Recruitment duration, a model prediction: 1 trial still running at the 2026-10-09 snapshot, fewer than the 5 needed for a median. Source: ClinicalTrials.gov / AACT (CTTI), public domain.

Which lead sponsors run the most Toxoplasmosis 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.
| Sponsor | Trials |

| National Institute of Allergy and Infectious Diseases (NIAID) | 7 |
| Glaxo Wellcome | 1 |
| GlaxoSmithKline | 1 |
| National Institutes of Health Clinical Center (CC) | 1 |
| Pfizer | 1 |
