An adverse event (AE) is defined as any study-related event that represents a change (positive or negative) in frequency or severity from a baseline (prestudy) event (if any), regardless of the presence of causal relationship or medical significance. Treatment-emergent adverse events are defined as any adverse event with a start date on or after the first study dose date. AEs are determined by the Investigator to be related or not related to the study drug. A serious AE (SAE) is defined by federal regulation as any AE occurring at any dose that results in any of the following outcomes: death, life-threatening AE, hospitalization or prolongation of existing hospitalization, a persistent or significant disability/incapacity, or a congenital anomaly/birth defect. Although a subject may have had 2 or more adverse experiences the subject is counted only once in a category. The same subject may appear in different categories.
An adverse event (AE) is defined as any study-related event that represents a change (positive or negative) in frequency or severity from a baseline (prestudy) event (if any), regardless of the presence of causal relationship or medical significance. Treatment-emergent adverse events are defined as any adverse event with a start date on or after the first study dose date. Adverse events were coded using MedDRA version 17.0. Preferred terms linked to injection site AEs are reported. Although a participant may have had 2 or more AEs, the subject is counted only once in each preferred term category. The same subject may appear in different preferred term categories.
Participants who were found to have gain \>=7% and \>=10% of their baseline weight at any point during the study (including unscheduled assessments) once treatment began.
The PANSS is a 30-item scale designed to assess various symptoms of schizophrenia including delusions, grandiosity, blunted affect, poor judgement, 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 is the sum of all 30 PANSS items and ranges from 30 to 210, with 30 indicating absence of symptoms of schizophrenia and 210 indicating extreme ratings of all 30 symptoms. Negative change from baseline scores indicate improvements in symptoms. Estimates (least square means and standard errors), 2-sided confidence intervals, and -1-sided P values are based on a repeated-measures linear regression model of the change from baseline score, with fixed effects for visit as a categorical variable, baseline score, treatment and treatment by visit interaction, assuming an unstructured covariance matrix.

A safety and tolerability review of the data from Day 1 to Day 15 was completed for the 3 subjects before the remaining 12 were dosed. |
| RBP-7000 | EXPERIMENTAL | All subjects that meet initial study entry criteria will receive a test dose of 0.25mg of oral risperidone. Subjects who continue to be eligible will return to the clinical unit in one week and receive a single dose of 60mg RBP-7000 after a 2 hour fast. Subjects will remain in the clinical unit for 14 days, then return for 10 additional weeks after discharge. |

| RBP-7000 | DRUG | 120-mg RBP-7000 dose delivered by subcutaneous injection every 28 days for a total of 13 injections (for roll-over participants, the first two injections took place under study RB-US-09-0010). A one-time down-titration to 90 mg RBP-7000 is permitted at the investigator's discretion should the participant have tolerability issues. Participants who received the 90-mg dose of RBP-7000 and exhibited a worsening in psychiatric symptoms could receive a one-time up-titration back to 120 mg RBP-7000 at the discretion of the investigator. RBP-7000 is a combination of the ATRIGEL Delivery System and risperidone. The ATRIGEL Delivery System allows for sustained-release of risperidone in a controlled manner. |
| Placebo | DRUG | Subcutaneous injection of placebo using the ATRIGEL Delivery System on Days 1 and 29 in the lower quadrant of the abdomen rotating right and left on day 1 and 29. |
| Risperidone | DRUG | Oral risperidone 0.25 mg tablets daily for the first two days of the screening period. The two 0.25 mg tablets confirmed whether study participants had any negative reaction to risperidone prior to receiving a long-acting injection of risperidone (RBP-7000). |
