Could a hormone be the hidden cause of diabetic nerve pain?

NCT ID NCT03481283

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

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.

Participants

About 40 people

The number the study aims to enrol. It can still change while the study runs.

Started

Feb 2018

Expected to finish

Jan 2029

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

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.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Subject has been diagnosed with Type-2 Diabetes. * Subject shows mild-to-severe peripheral neuropathy, as determined by Nerve Conduction Velocity (NCV) tests. Exclusion Criteria: * Subject has not been diagnosed with Type-2 Diabetes. * Subject shows average, or above average performance on Nerve Conduction Velocity (NCV) tests.
