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).
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.

Change From Baseline in Abnormal Involuntary Movement Scale (AIMS) Total Score at 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.
Time frame: Baseline and Day 14
Barnes Akathisia Rating Scale (BARS) Score
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.
Time frame: Day 14
Change From Baseline in Simpson Angus Rating Scale (SAS) Score
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.
Time frame: Baseline and Day 14
Maximum Concentration (Cmax)
The Cmax is peak plasma concentration, determined by visual inspection of the data.
Time frame: 0 hour (Predose) and 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12 hour post administration of JNJ-37822681 on Day 1 and Day 14
Concentration at Predose(Cpredose)
Cpredose is predose plasma concentration (intermittent days and predose Day 14).

Time frame: 0 hour (Predose) and 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12 hour post administration of JNJ-37822681 on Day 1 and Day 14
Average Concentration (Cavg)
The Cavg is average plasma concentration at steady state and it will be calculated as AUC (τ)/τ (where time τ is the dosing interval).
Time frame: 0 hour (Predose) and 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12 hour post administration of JNJ-37822681 on Day 1 and Day 14
Time to Reach Maximum Concentration(tmax)
The Tmax is time to reach the peak plasma concentration and will be determined by visual inspection of the data.
Time frame: 0 hour (Predose) and 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12 hour post administration of JNJ-37822681 on Day 1 and Day 14
Area Under the Plasma Concentration-Time Curve From 0 to 12 or 24 Hours Post Dosing (AUC 0-12h/24h)
The AUC 0-12h/24h is area under the plasma concentration-time curve from 0 to 12 or from 0 to 24 hours post dosing on Day 1 and Day 14 and will be calculated by trapezoidal summation.
Time frame: 0 hour (Predose) and 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12 hour post administration of JNJ-37822681 on Day 1 and Day 14
Area Under the Plasma Concentration-Time Curve From 0 to Tau Hours Post Dosing (AUC[0-tau])
The AUC(0-tau) is area under the plasma concentration-time curve from 0 to τ hours post dosing at steady state and it will be calculated by trapezoidal summation (where time τ is the dosing interval).
Time frame: 0 hour (Predose) and 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12 hour post administration of JNJ-37822681 on Day 1 and Day 14
Positive and Negative Syndromes Scale (PANSS) Total Score
The PANSS is a 30-item scale designed to assess various symptoms of schizophrenia including delusions, grandiosity, blunted affect, poor attention, and poor impulse control. The 30 symptoms are rated on a 7-point scale that ranges from 1 (absent) to 7 (extreme psychopathology). The PANSS total score consists of the sum of all 30 PANSS items and ranges from 30 to 210. Higher scores indicate worsening.
Time frame: Baseline up to 14 days after last study dose
Change From Baseline in Clinical Global Impression-Severity (CGI-S) Scale Score at Day 10 and 14
The CGI-S rating scale is a 7-point global assessment that measures the clinician's impression of the severity of illness exhibited by a participant. A rating of 1 is equivalent to "Normal, not at all ill" and a rating of 7 is equivalent to "Among the most extremely ill participants". Higher scores indicate worsening.
Time frame: Baseline, Day 10 and 14
