Healthy Volunteer
Conditions
Brief summary
This single-center, randomized, double-blind, two-period crossover study will evaluate the safety, tolerability, pharmacokinetics and pharmacodynamic effects of the combination of multiple doses of RO5285119 with a single dose of risperidone in healthy volunteers. Subjects will be randomized to one of 4 treatment sequences of two periods to receive multiple doses of RO5285119 plus a single dose of risperidone or risperidone placebo or multiple doses of RO5285119 placebo plus a single dose of risperidone or risperidone placebo, with a washout period of approximately 3 weeks between treatment periods. Anticipated time on study is up to 12 weeks (from screening through study completion).

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Pharmacokinetics of single dose risperidone in combination with multiple doses of RO5285119: Maximum plasma concentration (Cmax) | Pre-dose to 24 hours post-dose |
| Pharmacokinetics of single dose risperidone in combination with multiple doses of RO5285119: Area under the concentration-time curve (AUC) | Pre-dose to 24 hours post-dose |
Secondary
| Measure | Time frame |
|---|---|
| Pharmacodynamic assessments for risperidone: Level of sedation | Pre-dose to 24 hours post-dose |
| Safety: Incidence of adverse events | approximately 12 weeks |
| Pharmacokinetics of RO5285119 in combination with single dose risperidone: Area under the concentration-time curve (AUC) | Day1 to Day 18 |
| Pharmacokinetics of RO5285119 in combination with single dose risperidone: Maximum plasma concentration (Cmax) | Day 1 to Day 18 |
| Pharmacodynamic markers for risperidone: Prolactin levels | Pre-dose to 6 hours post-dose |
