Trials per phase
9 of the 9 trials are tagged with Multiple Chemical Sensitivity itself; the rest are tagged with a narrower condition beneath it.
When did Multiple Chemical Sensitivity trials start? (7)
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 2
- Not applicable
- Observational
Top of scale: 3
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 |
|---|---|
| 2025 | 1 |
| 2024 | 1 |
| 2021 | 1 |
| 2013 | 1 |
| 2011 | 1 |

No forecast is made for this condition: it averages 0.6 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.

Status as registered on ClinicalTrials.gov. Each trial is counted once.
Which lead sponsors run the most Multiple Chemical Sensitivity trials? (1)
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 |
|---|---|
| Institut National de la Santé Et de la Recherche Médicale, France | 2 |
Which serious adverse events do Multiple Chemical Sensitivity trials report? (1)
Shown in this order: most subjects affected first. Subjects affected summed across trials, a cross-trial signal, not a rate.
| Adverse event | Subjects affected | Trials |
|---|---|---|
| Elevated CRP Levels | 1 | 1 |
