A Two-part Single and Multiple Dose Study to Assess the Safety , Pharmacokinetics and Effects of AZD3293 in Healthy Japanese Young and Elderly Volunteers

This is a Phase I, randomised, double-blind, placebo-controlled, single centre study to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of AZD3293 following single and multiple ascending dose administration to healthy subjects. This study consists of two parts, ie, single dose part with young healthy subjects (Part 1) and single and multiple dose part with elderly healthy subjects (Part 2). The study design allows a gradual escalation of dosage levels between sequential cohorts with safety monitoring to ensure the safety of the healthy subjects.
