Study to Assess the Safety, Tolerability and Pharmacokinetics of AZD2066 in Young and Elderly Healthy Subjects


The purpose of this study is to investigate the safety and tolerability of AZD2066 using multiple escalating dose panels. There will be separate panels for young healthy volunteers and elderly healthy volunteers. Each panel will contain 10 volunteers who will randomly receive AZD2066 or placebo. One panel will be run at a time with a fixed dose given. After the completion of each panel, a Safety Review Committee will decide if the study can proceed to the next dose panel.

Full Title of Study: “A Phase I, Single-centre, Randomised, Double-blind, Parallel Group, Placebo-controlled Study to Assess the Safety, Tolerability and Pharmacokinetics of AZD2066 in Young and Elderly Healthy Subjects After Oral Multiple Ascending Doses”

Clinical Trial Outcome Measures

Primary Measures

  • Safety and tolerability of AZD2066 by assessment of vital signs, laboratory variables and ECG
    • Time Frame: Assessments taken at visit 1 (enrolment), defined time points pre dose and post dose during visit 2 (residential period): days -1 through to day 15 and follow up visit 3

Secondary Measures

  • Safety and tolerability of AZD2066 by assessment of adverse events
    • Time Frame: Non serious adverse events will be collected from the start of Visit 2 until the end of the study. Serious adverse events will be collected from signing of consent until end of study.
  • Investigate PK profile (including dose proportionality, degree of accumulation and time dependancy) of AZD2066 (and possible relevant metabolites).
    • Time Frame: PK sampling taken at defined timepoints during residential period and follow-up.
  • Investigate CNS effects of AZD2066
    • Time Frame: Psychometric test battery performed at defined timepoints during the residential period. Test on day -1 for training purposes.
