Clinical Trial Summary

The primary aim is to collect data to determine the correct effect size on the primary outcome to aid in the design of a larger study: The primary outcome is to determine if lipoic acid and omega-3 fatty acids can improve cognitive function in people with multiple sclerosis that have cognitive dysfunction.


Clinical Trial Description

The study is designed as a randomized, double-blind, placebo-controlled pilot trial. The primary aim of the study is to determine if lipoic acid and omega-3 fatty acids can improve cognitive function over 12-weeks in people with multiple sclerosis that have a baseline score of at least two standard deviations below normative values on any one of four cognitive tests that include, Paced Auditory Serial Addition Task (PASAT), Stroop Color-Word Test, California Verbal Learning Test-II (CVLT-II), and Controlled Oral Word Association Test (COWAT).

The secondary aim is to determine treatment effects on markers of endothelial inflammation, insulin dysregulation, and mitochondrial dysfunction that may be related to cognitive dysfunction by measuring s-ICAM-1 levels, homeostasis model of insulin resistance (HOMA-IR), and MRI phosphorus imaging in a subset of study participants. The study will also measure safety by adverse event reports and laboratory measures; plasma fatty acid levels; serum lipoic acid levels. ;
