Study Description(click to expand)

This is a double-blind, exploratory proof of concept, cross-over trial of the D1 antagonist ecopipam for subjects with augmented Restless legs syndrome (RLS). Investigators will recruit 10 subjects taking dopamine agonists for RLS who are currently experiencing augmentation. The goal is to have 8 completers. There is no power analysis as this is an exploratory study and there is no previous data on treatment of augmentation. "Meaningful improvement" is not even established. A safety analysis will be done after 5 subjects have been enrolled. Duration of study and is based mostly on contracted drug availability for this pilot study.
