Which countries run stem-cell trials for Multiple Sclerosis?

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 Multiple Sclerosis

Transplant work concentrates in accredited haematology units in Europe, North America and a few other centres, with published registry outcomes. Commercial mesenchymal offers cluster in tourism markets and do not carry that accreditation or reporting.

Where recruitment is actually open

What travelling for a trial actually involves

Distance changes the risk calculus. Registered studies are designed around continuity of care, so a site will normally decline participants it cannot monitor — which is exactly the safeguard a commercial clinic does not apply.

Multi-country studies, named

Registered studies with sites in more than one country — the clearest evidence of collaboration rather than a single-centre series.

• NCT06665165 — AMX0114 in Adult Participants With Amyotrophic Lateral Sclerosis (Canada, United States)
• NCT05003388 — Safety of Cultured Allogeneic Adult Umbilical Cord Derived Mesenchymal Stem Cell Intravenous Infusion for MS (Antigua and Barbuda, Greece)

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 (4), 2021 (8), 2022 (1), 2023 (5), 2025 (5), 2026 (4). Activity for this condition spans 1997 to 2026, which shows whether interest is growing, flat or past its peak.

Frequently asked

Which countries run stem-cell trials for Multiple Sclerosis?

Sites are registered in 31 countries; the largest is United States (~46% of country mentions, 2026-08-29).

Does a country with many trials mean better treatment there?

It does not follow. A country can host many trials and still have an unregulated commercial sector selling something quite different to visitors.

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.
