Condition progressive supranuclear palsy
Treatment alpha-lipoic acid and l-acetyl carnitine
Phase phase 1
Sponsor Weill Medical College of Cornell University
Start date December 2011
End date December 2013
Trial size 15 participants
Trial identifier NCT01537549, IRB1006011088


Studies have shown that alpha-lipoic acid and L-acetyl carnitine may have some neuroprotective activities and it is hoped that they could be helpful for people with neurodegenerative illnesses such as progressive supranuclear palsy (PSP).

The purpose of this study is to find out whether the nutritional supplement alpha-lipoic acid/L-acetyl carnitine is safe and well-tolerated in individuals with PSP when given daily, and whether it affects their well-being, brain scan measurements and blood tests that measure the energy metabolism in cells.
