Unproven stem-cell treatments: warning signs
Clinics and companies sell stem-cell and immune 'cures' for type 1 diabetes outside proper trials. How to tell real research from a commercial offer.
When you’re desperate for a cure, offers of stem-cell treatment can look like hope. Some clinics and companies sell treatments for type 1 diabetes that have never been shown to work in a proper trial. They are often expensive, sometimes abroad, and not without risk.
None of the experimental treatments in our tracker can be bought. Real experimental treatments are given inside clinical trials, free for participants, with ethics approval and follow-up. The approved products in the tracker, like pumps and sensors, are ordinary prescribed care.
Warning signs
- The same treatment for many unrelated diseases. Type 1 diabetes, Parkinson’s, autism, long COVID, hair loss: real therapies are developed for one disease at a time.
- A “get treatment” button, testimonials and a price, instead of a trial registration with inclusion criteria.
- Treatment outside clinical trials, for example through the US “Right to Try” law, or at a clinic abroad.
- Regulatory terms presented as approval. An FDA “Fast Track”, “Breakthrough” or “RMAT” designation only speeds up the review. It doesn’t show that a treatment works, and it isn’t an approval.
- A trial registration used as a seal of quality. The FDA warns that a listing on ClinicalTrials.gov doesn’t mean a product is approved or even legal.
- No independent results: only the company’s own figures, press releases or patient stories.
The FDA’s advice is blunt: if you are asked to pay for a stem-cell product outside an FDA-overseen trial, you are likely being deceived. In type 1 diabetes, the only approved cell therapy is a donor islet product in the US, Lantidra, for adults with severe, repeated lows.
Questions to ask
The International Society for Stem Cell Research has a patient guide and a list of questions to ask before an unproven treatment. The most important ones:
- Is this part of a registered clinical trial, approved by an ethics committee and a regulator?
- What is the evidence that it works for type 1 diabetes, published in a peer-reviewed journal?
- Who pays? In a real trial, participants don’t pay for the experimental treatment.
- What are the risks, and who takes care of me if something goes wrong?
And ask your diabetes team. They hear about these offers too, and can tell you whether there’s a real trial you could join instead.
