UDCA - Ursodeoxycholic acid

Hello all 

last fall there was a news story I noticed on this site about  'Ursodeoxycholic acid' (UDCA), it's a liver drug thats been in use for a couple of decades. It has been identified as a potential treatment for slowing the progression of Parkinson's. They mentioned clinical trials may begin in 2014. I'm curious to know if anyone has a more current update on any news since last September. Haven't been able to find anything current on the web.
