Normast3 for Adults With Diabetic Polyneuropathy

Summary

The goal of this clinical trial is to find out if a new supplement called Normast® 3 can help reduce nerve pain and improve nerve function in adults with diabetic polyneuropathy (DPN). DPN is a common complication of diabetes that damages nerves, often causing burning, tingling, or stabbing pain, as well as problems with the autonomic nervous system, which controls things like sweating and heart rate.

The main questions this study aims to answer are:

Does taking Normast® 3 lower daily pain levels after 12 weeks of treatment? Does it improve the function of small nerve fibers and the autonomic nervous system compared with a placebo (a look-alike tablet with no active ingredients)? Study design This is a randomized, double-blind, placebo-controlled clinical trial. This means participants are randomly assigned to receive either Normast® 3 or placebo, and neither participants nor researchers will know who is receiving which treatment until the study ends.

Who can take part About 40 adults aged 18 to 80 who have diabetic polyneuropathy affecting both small and large nerve fibers will be enrolled. Participants must have stable diabetes treatment for at least 3 months and be able to take oral medication. People with other nerve diseases, major psychiatric conditions, or serious health problems will not be able to take part.

What participants will do Take Normast® 3 or placebo tablets twice a day for 12 weeks while continuing their usual treatments Complete pain and symptom questionnaires Have neurological examinations including quantitative sensory testing, heart and blood pressure tests, the dynamic sweat test, and small skin biopsies to look at intraepidermal nerve fibers Return for follow-up visits at 12 weeks (end of treatment) and 24 weeks (long-term follow-up) Safety and follow-up Researchers will check participants' safety through blood and urine tests and by monitoring any side effects. Participants can stop the study at any time.

Where the study takes place This study is being conducted at the Department of Human Neuroscience, Sapienza University of Rome (Italy).

Interventions

DIETARY_SUPPLEMENT

Normast® 3 - a food for special medical purposes (FSMP) containing co-micronized palmitoylethanolamide (PEA) with rutin and hydroxytyrosol. It is designed to support the management of diabetic polyneu

Normast® 3 is a food for special medical purposes (FSMP) containing co-micronized palmitoylethanolamide (PEA) with rutin (5:1) and hydroxytyrosol. Each tablet provides 360 mg PEA/rutin and 15 mg hydroxytyrosol. The product is formulated to target neuroinflammation and vascular dysfunction involved in diabetic polyneuropathy. In this study, participants will take one tablet twice daily (after lunch and after dinner) for 12 weeks, in addition to their standard diabetes care.

DIETARY_SUPPLEMENT

Placebo

Placebo tablets are visually and taste-matched to Normast® 3 but contain no active ingredients. Each tablet is composed of inert excipients (mainly microcrystalline cellulose and other standard tablet components). Participants will take one placebo tablet twice daily (after lunch and after dinner) for 12 weeks, in addition to their standard diabetes care.
