Could a hormone be the hidden cause of diabetic nerve pain?
NCT ID NCT03481283
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is investigating whether the hormone amylin, which is elevated in type 2 diabetes, is linked to peripheral neuropathy (nerve damage). Researchers will collect blood and skin samples from 40 adults with type 2 diabetes and mild-to-severe neuropathy. They will measure amylin levels in red blood cells and blood vessel walls, then compare them to nerve function and pain sensitivity. The goal is to see if higher amylin levels are associated with worse nerve symptoms.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If a link is found, this could point toward new ways to detect or treat diabetic nerve damage.
- What could go wrong
- This is a small, early observational study. It only looks for a correlation, not a cause, and may not lead to any treatment.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Forty patients, age 18 years or older, with previously diagnosed DMII and referred to the Kentucky Neuroscience Institute Neuromuscular Laboratory for nerve conduction velocity studies (NCVs) will be asked to participate in the study. Because this is a pilot study, every effort will be made to select a broad distribution of male and female patients, regardless of ethnicity, who are mildly to severely symptomatic based on NCVs.
