Research activity over time

Registration of new studies slowed: 2 newly registered studies in 2017–2021 against 8 in 2012–2016. The first study in this registry query was posted in 2011; the registry now holds 12 in total, of which 3 are recruiting. Counting is by first-posted date, so the series reflects when research was registered — not enrolment, completion or results.

What to verify before interpreting a study or offer

1. The exact product, cell source, processing, dose and delivery route.
2. The indication, study phase, comparator, endpoints, status and eligibility criteria.
3. Whether the proposed use is authorised, part of a registered trial or otherwise investigational.
4. Provider and manufacturing authorisations, release testing, traceability and adverse-event reporting.
5. How the proposal compares with current standard care, reviewed by an independent physician.
