研究概览
简要总结
The purpose of this study is to evaluate safety, tolerability and pharmacokinetics (explores what the body does to the drug) of JNJ-37822681 in participants with stable schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self).
详细描述
This is a double-blind (neither physician nor participant knows the treatment that the participant receives), multi-center (conducted in more than one center), randomized (treatment group assigned by chance), and multiple-dose titration study of JNJ-37822681 in participants with stable schizophrenia. The total study duration will be approximately of 8 weeks per participant, consists of 4 parts: Screening (that is, 21 days before study commences on Day 1); Double-blind treatment (14 days); Follow-up (7 to 14 days after last dose administration). Participants will be randomly assigned to treatment with ascending dose levels of JNJ-37822681 once daily and twice daily. Efficacy will primarily be evaluated by Positive and Negative Syndrome Scale and Clinical Global Impression-Severity scale. Safety will be Barnes Akathisia Rating Scale, Abnormal Involuntary Movement Scale and Simpson Angus Rating Scale. Participants' safety will be monitored throughout the study.

JNJ-37822681 10 milligram
JNJ-37822681 oral capsule will be administered at a starting dose of 10 milligram (mg) twice daily for the first 3 days and thereafter dose will be titrated from Day 3 to Day 10 up to 80 mg per day and will be continued at same dose up to Day 14.
干预措施: JNJ-37822681 (Drug)
JNJ-37822681 20 milligram and placebo

结局指标
主要结局
Change From Baseline in Abnormal Involuntary Movement Scale (AIMS) Total Score at Day 14
时间窗: Baseline and Day 14
The AIMS rates the severity of involuntary movements from 0 (none) to 4 (severe), including facial and oral movements, extremity movements, trunk movements, global and judgments, and 2 additional items concerning dental status (yes/no). A total score (ranging from 0 to 28) will be calculated as the sum of items 1 to 7.
Barnes Akathisia Rating Scale (BARS) Score
时间窗: Day 14
The BARS includes an objective rating, 2 subjective ratings of symptoms of akathisia (awareness of restlessness and reported distress related to restlessness: range 0 to 3), and a global clinical rating of akathisia, ranging from 0 (absent) to 5 (severe). The global rating score, that is scored separately, is the most relevant measure of severity of akathisia. Higher scores denote worsening akathisia.
Change From Baseline in Simpson Angus Rating Scale (SAS) Score
时间窗: Baseline and Day 14
The SAS rates 10 items from 0 (normal) to 4 (extreme), including gait, arm dropping, shoulder shaking, elbow rigidity, wrist rigidity, leg pendulousness, head rotation, Glabellar tap, tremor and salivation. The SAS global score is the average score (total sum of items score divided by the number of items) and ranges between 0 and 4, where the higher score denotes more severe condition of extra pyramidal symptoms.
