Primary Outcome Measures:
  • The time to first relapse event in the Double-blind Phase [ Time Frame: Approximately 6 months ] [ Designated as safety issue: No ]
    Time to relapse is defined as the time between randomization to treatment in the Double-Blind Phase and the first documentation of a relapse.


Secondary Outcome Measures:
  • The change in score from baseline to endpoint in Positive and Negative Syndrome Scale (PANSS) (total and subscales) in the Double-blind Phase [ Time Frame: Baseline and approximately 6 months ] [ Designated as safety issue: No ]
    PANSS provides a total score (sum of the scores of all 30 items) and scores for 3 subscales, the positive subscale (7 items), the negative subscale (7 items), and the general psychopathology subscale (16 items). Each item is rated 1 (absent) to 7 (extreme).

  • The change from baseline to endpoint in Clinical Global Impression Severity (CGI-S) scale in the Double-blind Phase [ Time Frame: Baseline and approximately 6 months ] [ Designated as safety issue: No ]
    The CGI-S rating scale is used to rate the severity of a patient's overall clinical condition on a 7-point scale ranging from 1 (not ill) to 7 (extremely severe).

  • The change from baseline to endpoint in Personal and Social Performance (PSP) scale in the Double-blind Phase [ Time Frame: Baseline and approximately 6 months ] [ Designated as safety issue: No ]
    The PSP scale measures personal and social functioning in the domains of: a) socially useful activities, b) personal and social relationships, c) self-care, and d)disturbing and aggressive behavior.

Arms Assigned Interventions
Experimental: Paliperidone palmitate 3-month (PP3M) Drug: PP3M 175 mg eq.
Type= exact number, unit= mg eq., number= 175, form= injection, route= intramuscular use. One injection every three months up to the patient has a relapse event or meet discontinuation criteria.
Drug: PP3M 263 mg eq.
Type= exact number, unit= mg eq., number= 263, form= injection, route= intramuscular use. One injection every three months up to the patient has a relapse event or meet discontinuation criteria.
Drug: PP3M 350 mg eq.
Type= exact number, unit= mg eq., number= 350, form= injection, route= intramuscular use. One injection every three months up to the patient has a relapse event or meet discontinuation criteria.
Drug: PP3M 525 mg eq.
Type= exact number, unit= mg eq., number= 525, form= injection, route= intramuscular use. One injection every three months up to the patient has a relapse event or meet discontinuation criteria.
Placebo Comparator: Placebo Drug: Placebo (20% Intralipid emulsion)
Form= injection, route= intramuscular use. One injection every three months up to the patient has a relapse event or meet discontinuation criteria.

Detailed Description:

This is a randomized (the study drug is assigned by chance), double blind (neither physician nor patient knows the treatment that the patient receives), parallel group (each group of patients will be treated at the same time), placebo-controlled (an inactive substance is compared with a drug to test whether the drug has a real effect in a clinical trial) multicenter study. The study consists of 4 phases: a Screening Phase (up to 3 weeks); a 17-week flexible dose open-label Transition Phase (open-label phase means that all people know the identity of the intervention); a 12-week fixed dose open-label Maintenance Phase; and a randomized, double-blind, fixed dose, placebo-controlled relapse prevention phase (referred to as the Double-blind Phase). Patients who meet specific stabilization criteria will enter the Double-blind Phase at Week 29. Patients will be randomly assigned, in a 1:1 ratio, to receive either a fixed dose of PP3M or placebo. The Double-blind Phase will be of variable duration; patients will remain in the study until they experience a relapse event or meet discontinuation criteria.

Criteria

Inclusion Criteria:

  • Patients with schizophrenia for more than 1 year
  • A total score in the Positive and Negative Syndrome Scale (PANSS) < 120
  • Signed informed consent
  • Women must not be pregnant, breastfeeding, and if capable of pregnancy must practice an effective method of birth control
  • Men must agree to use a double-barrier method of birth control
  • Be medically stable on the basis of clinical laboratory tests, physical examination, medical history, vital signs, and electrocardiogram (ECG) Exclusion Criteria:
  • A diagnosis other than schizophrenia, e.g., dissociative disorder, bipolar disorder, major depressive disorder, schizoaffective disorder, schizophreniform disorder, autistic disorder, primary substance-induced psychotic disorder, dementia-related psychosis
  • Relevant history or current presence of any significant or unstable medical condition(s) determined to be clinically significant by the Investigator (ie, obesity, diabetes, heart disease etc)
