Study of Subcutaneous Continuous Administration of Levodopa/Carbidopa Solution (ND0612) in Healthy Volunteers

A Phase I, Single Dose, Single-centre, Randomized, Double-blind, Placebo-controlled Dose Escalation Study Evaluating Safety, Tolerability and Levodopa Plasma Concentration Following Administration of Subcutaneous Continuously-delivered Levodopa/Carbidopa Solution (ND0612) in Healthy Volunteers

It will be a single dose, single-center, randomized, double-blind, placebo-controlled dose escalation study of SC continuously-delivered LD/CD solution (ND-0612) for 24 hours in healthy volunteers.

Objectives are to determine:

1. the maximal tolerated dose of SC ND-0612
2. the steady state plasma concentration of LD and CD following SC ND-0612 administration.

Each treatment group will include 6 healthy volunteers. Dosing will be done in a sequential manner.
