What this trial studies

This clinical trial aims to evaluate the effectiveness of a combination of alpha lipoic acid and vitamin B preparations in treating diabetic polyneuropathy in patients with type 2 diabetes mellitus. It is a single-center, randomized, double-blind, placebo-controlled study that will assess improvements in neuropathic symptoms and overall diabetes management over a 12-week period. Participants will be monitored for changes in symptom scores, glucose levels, and other health indicators. The study will take place at the Klinik Rawatan Keluarga and diabetes clinic at Hospital Universiti Sains Malaysia from May 2024 to September 2025.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and over diagnosed with type 2 diabetes mellitus and diabetic polyneuropathy.

Not a fit: Patients with peripheral vascular disease, renal impairment, or those on certain medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve nerve function and quality of life for patients suffering from diabetic polyneuropathy.

How similar studies have performed: Previous studies have shown promising results with similar combinations of alpha lipoic acid and vitamin B for diabetic neuropathy, indicating potential for success.
