There is a clinical trials.gov record (with phase II data) at
http://clinicaltrials.gov/ct2/result...&Search=Search

Also a list of other clinical trials for other conditions. It was also being studied as a treatment for Huntington’s.

The Parkinson Pipeline Project treatment database was following the progress of GM1 Ganglioside for a number of years. See:

The latest news was that as of June, 2006, the treatment phase of the study was closed to recruitment. Then 6 years to analyze and publish the data? I agree the delays were likely due to a lack of a commercial sponsor. But this was one of the rare successful phase II trials. You’d think there would be some interest in developing it further?
