Summary

This trial is studying the combination of fish oil and salsalate to see if it is an effective treatment for diabetic peripheral neuropathy (DPN). DPN is a common complication of diabetes that can lead to severe pain, sensory deficits, foot ulcers, and amputations. There is no currently no effective treatment for DPN.

Who is the study for?
Adults over 18 with type 2 diabetes and diabetic peripheral neuropathy can join this trial. They should have an HbA1c level below 9.5% and be willing to use contraception if necessary. People with other types of neuropathy, severe kidney issues, recent transplants, or certain medical conditions that could interfere with the study cannot participate.
What is being tested?
The trial is testing whether taking fish oil capsules (rich in omega-3 fatty acids) alone or combined with salsalate tablets can help people with diabetic nerve pain by changing their blood lipid profile and increasing anti-inflammatory metabolites.
What are the potential side effects?
Possible side effects include minor risks associated with fish oil such as a fishy aftertaste, nausea, and loose stools. Salsalate may cause stomach upset, ringing in the ears, or allergic reactions for those sensitive to it.
