Which countries run stem-cell trials for Diabetes (Type 1 & 2)?

Country distribution

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 Diabetes (Type 1 & 2)

Islet and immune-reset work concentrates in a handful of academic centres in North America, Europe and East Asia with encapsulation or transplant programmes. A clinic elsewhere offering intravenous MSCs for type 2 diabetes is not adjacent to that research in any technical sense.

Where recruitment is actually open

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.

• NCT05791201 — A Safety, Tolerability, and Efficacy Study of VX-264 in Participants With Type 1 Diabetes (Canada, Germany, Italy, Netherlands, Switzerland, United Kingdom)

Why trial geography is not a shortlist

Trial locations follow regulation, funding and sponsor headquarters, not clinical quality. Countries with clear conditional pathways for advanced therapies and large public research budgets register more studies. A country appearing here also says nothing about whether commercial clinics there operate under the same oversight as the registered trials.

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), 2021 (2), 2022 (3), 2023 (1), 2024 (1), 2025 (2). Activity for this condition spans 2003 to 2025, which shows whether interest is growing, flat or past its peak.

Frequently asked

Which countries run stem-cell trials for Diabetes (Type 1 & 2)?

Sites are registered in 23 countries; the largest is United States (~30% 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.
