Brief Summary

An Open-Label Study in Healthy Male and Female Subjects to Identify the Concentration that Provides Optimal Bioavailability of Levodopa Infused Subcutaneously via a Pump System; and to Compare the Bioavailability of Levodopa/Carbidopa Solution to that of Levodopa/Carbidopa Intestinal Gel (LCIG), Infused via a Naso-Jejunal Tube
