ORLANDO, Fla., Nov. 19, 2010 /PRNewswire/ -- Schizophrenia is a chronic and disabling brain disorder that affects 1 percent of the U.S. population and results in substantial medical and societal costs, in particular from use of health-care resources. It also can have devastating health-related and social effects on people with the disease, their families and caregivers.
A pre-specified analysis from a longer-term clinical study presented at the U.S. Psychiatric and Mental Health Congress today suggests that psychiatric hospitalization rates decreased for adults with schizophrenia who were treated with INVEGA® SUSTENNA® (paliperidone palmitate), a long-acting atypical antipsychotic for acute and maintenance treatment of schizophrenia in adults.
"This study suggests that INVEGA SUSTENNA may have potential to reduce psychiatric hospitalization rates," said Chris M. Kozma, PhD, independent researcher and adjunct professor, University of South Carolina, Columbia, and consultant for Ortho-McNeil Janssen Scientific Affairs, L.L.C., the sponsor of the study. "While the results will need further investigation to confirm these observations, a treatment that can potentially lead to reduced hospitalizations for schizophrenia may offer economic benefits to health-care systems that pay for schizophrenia-related inpatient care."
Study MethodsData for the analysis were from two phases of the clinical trial: a double-blind, randomized, relapse-prevention maintenance phase that compared INVEGA SUSTENNA to placebo and a one-year open-label extension of the study, during which all patients were treated with INVEGA SUSTENNA.
The change in schizophrenia-related hospitalization rates between the two phases of the study was evaluated for the group of patients treated with INVEGA SUSTENNA and for the group that received placebo. Data were obtained from an investigator-completed resource-use questionnaire. Overall change in hospitalization ra
