Study summary

Open-Label Extension to the double-blind effectiveness and safety study R076477-SCH-305 to evaluate long-term safety and tolerability in patients with schizophrenia.

Read the detailed description

The primary objective of the open-label extension trial was the long-term assessment of safety and tolerability of flexibly-dosed ER OROS paliperidone (3 to 15 mg/day) in patients with a diagnosis of schizophrenia. Other measures assessed in the extension study included: change in the total Positive and Negative Syndrome Scale (PANSS) score; change in PANSS subscale (positive and negative) scores; overall functioning, as measured by the Clinical Global Impression Scale-Severity (CGI-S); personal and social functioning, as measured by the Personal and Social Performance Scale (PSP); and quality of life parameters, as measured by the Schizophrenia Quality of Life Scale, Revision 4 (SQLS-R4). Paliperidone ER OROS® tablet formulation (3 to 15 mg/day) to be taken orally for 52 weeks

What researchers measure

Primary outcomes

  1. Flexibly-dosed ER OROS paliperidone 3 mg to 15 mg/day was safe and well tolerated in patients with schizophrenia. The safety profile was generally consistent with that observed in subjects after short-term use in the double-blind studies

Secondary outcomes

  1. Findings showed stability of symptoms or further improvements in the severity of symptoms associated with schizophrenia (PANSS), personal and social functioning (PSP), global severity of illness (CGI-S), and patient-rated symptoms and well-being (SQLS)
