Which countries run stem-cell trials for Ulcerative Colitis?
Sampled registrations place sites in 7 countries. United States is the largest single contributor at roughly 33% of country mentions. Snapshot 2026-08-29.
Country distribution
| Country | Studies with a site there |
|---|---|
| United States | 5 |
| China | 4 |
| France | 2 |
| Italy | 1 |
| United Kingdom | 1 |
| Jordan | 1 |
| Spain | 1 |
A study with sites in several countries is counted once per country, taken from the location block of each registry record.
What the map means for Ulcerative Colitis
Registered work follows gastroenterology research centres with endoscopy scoring capability. Commercial offers rarely include endoscopic assessment at all, which means they cannot demonstrate the outcome that defines response in this disease.

What travelling for a trial actually involves
Cross-border participation fails on logistics more often than on eligibility: follow-up schedules, local insurance, visa duration and who pays for complications. A site that cannot answer those in writing is not going to enrol you.
Multi-country studies, named
Registered studies with sites in more than one country — the clearest evidence of collaboration rather than a single-centre series.
No sampled study for this condition lists sites in more than one country, so the research base here is made of single-centre work rather than multinational collaboration.
Why trial geography is not a shortlist
The map is drawn by policy and money. Permissive or well-defined regulatory pathways attract registrations and large research budgets attract more still. None of that transfers to the private clinic advertising in the same city, which may operate under no comparable supervision.
Before treating geography as a shortlist, read the legality overview by country and what "best country" actually means here.
When these studies started
Registrations by start year since 2020: 2020 (2), 2022 (3), 2025 (1), 2026 (1). Activity for this condition spans 2010 to 2026, which shows whether interest is growing, flat or past its peak.
Frequently asked
Which countries run stem-cell trials for Ulcerative Colitis?
Sites are registered in 7 countries; the largest is United States (~33% of country mentions, 2026-08-29).
Does a country with many trials mean better treatment there?
No. Registration volume reflects the research and regulatory environment, not the quality of care a private clinic there will provide.
Are trial sites and commercial clinics the same thing?
Usually not. The hospital running a registered study is often unrelated to clinics marketing treatments to international patients in the same city.
