Summary

This study tested whether a gene therapy called VM202 could safely reduce pain in people with diabetic peripheral neuropathy. Over 500 adults with type 1 or type 2 diabetes received either VM202 injections or a placebo in their legs. The main goal was to see if the treatment lowered average daily pain scores over 90 days, while also monitoring for side effects.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Engensis (VM202) gene therapy

What this could lead to

If successful, this gene therapy could provide a new way to reduce chronic nerve pain in people with diabetes, potentially offering longer-lasting relief than current medications.

What could go wrong

This is a Phase 3 trial, but results may not show a clear benefit over placebo. Gene therapies can have unexpected side effects, and the pain relief might be modest or temporary.
