A Single and Multiple Ascending Dose Study to Evaluate the Safety and Pharmacokinetics of PU-AD in Healthy Subjects

Each subject in all cohorts will be administered an oral solution of PU AD or placebo under fasting conditions. Each cohort will contain subjects randomized to active treatment or placebo, evaluating safety and tolerance.
