Official title

Nicotinamide Riboside in Diabetic Polyneuropathy

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

At the current time there is no effective disease modifying therapy for diabetic neuropathy (DN). The proposed study design employs a quantifiable early measure of DN, intraepidermal nerve fiber density (IENFD), allowing for accurate assessment of actual nerve fiber density. Preclinical data supports the use of Niagen® (3-(Aminocarbonyl)-1-β-D-ribofuranosyl-pyridinium chloride - NR) as a potential therapy for diabetic neuropathy. Phase I data indicates safety in humans. This study seeks to investigate the use of Niagen® (NR) as a potential treatment for diabetic neuropathy in subjects with type 2 diabetes mellitus or impaired glucose tolerance over a 6 month period. The endpoint measures in addition to the IENFD with determine changes in clinical and electrophysiological outcomes, quality of life and biochemical measures.
