Brief summary
The purpose of this study is to investigate the safety, tolerability and pharmacokinetics of AZD2066 when given as multiple doses to Japanese healthy male subjects. Four (4) consecutive multiple-ascending panels are planned. Subjects will start with an initial single dose that is followed by a wash-out period of 48 hours to adequately define the single-dose pharmacokinetics. For the third and forth dose panels, the wash-out period will be extended to be 96 hours to evaluate the safety of subjects. Thereafter the subjects will be dosed once daily for 10 days. Ten (10) subjects will be allocated to each dose panel and randomized to receive either AZD2066 or placebo.
Detailed description
The purpose of this study is to investigate the safety, tolerability and pharmacokinetics of AZD2066 when given as multiple doses to Japanese healthy male subjects. Four (4) consecutive multiple-ascending panels are planned. Subjects will start with an initial single dose that is followed by a wash-out period of 48 hours to adequately define the single-dose pharmacokinetics. For the third and forth dose panels, the wash-out period will be extended to be 96 hours to evaluate the safety of subjects. Thereafter the subjects will be dosed once daily for 10 days. Furthermore, the study has been expanded to include two additional panels with increment of dose during the multiple dosing period (12 days) in order to obtain sufficient information on safety and tolerability of multiple dosing of AZD2066 in Japanese subjects at higher levels of exposure. Ten (10) subjects will be allocated to each dose panel and randomized to receive either AZD2066 or placebo.
Interventions
DRUGAZD2066
Oral solution administered orally once per day on day 1, and then day 3 through to day 12 for the first and second dose panels and day 5 through to day 14 for the third and fourth dose panels. For the fifth and sixth panels, oral solution administered once per day on day 1, and then day 5 through to day 16. Specific dose depends on dose panel.
DRUGPlacebo
Oral solution administered orally once per day on day 1, and then day 3 through to day 12 for the first and second dose panels and day 5 through to day 14 for the third and fourth dose panels. For the fifth and sixth panels, oral solution administered once per day on day 1, and then day 5 through to day 16.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Safety and tolerability by assessment of vital signs, laboratory variables and ECG | 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
| Measure | Time frame |
|---|---|
| Investigate pharmacokinetic profile (including dose proportionality, degree of accumulation and time dependancy) of AZD2066 in Japanese healthy male subjects | Blood sampling at defined timepoints during residential period and follow-up |
| Investigate CNS effects of AZD2066 in Japanese healthy male subjects | Psychometric test battery performed at defined timepoints during the residential period. Test on day -1 for training purposes. |
