Brief Title  ICMJE Safety and Efficacy of an Anti-Psychotic in Patients With Schizophrenia
Official Title  ICMJE A Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Efficacy and Safety of 50 and 100 Mg-eq of Paliperidone Palmitate in Patients With Schizophrenia
Brief Summary The purpose of this study is to determine the efficacy (how well the drug works), safety, and side effects of paliperidone palmitate injection compared to placebo in the treatment of the symptoms of schizophrenia in adults. The placebo used in this study was a nutritional substance known as 20% Intralipid emulsion given to patients requiring intravenous feedings.
Detailed Description Paliperidone palmitate is an aqueous suspension that releases paliperidone gradually over a period of about 1 month and is under development to provide a sustained and stable level of paliperidone. This is a randomized (patients will be assigned to different treatment groups based solely on chance), double-blind (neither the patient nor the physician will know if placebo or drug is being given and at what dose), placebo-controlled, multicenter study in patients with schizophrenia. The study consists of a screening period (maximum 5 days, including a 3-day washout of psychotropic medications other than antidepressants, if applicable); a 7-day, open-label, oral run-in period; and a 64-day double-blind treatment period. The total duration of the study is approximately 11 weeks. Efficacy will be evaluated during the study using the Positive and Negative Symptom Scale for Schizophrenia (PANSS) and the Clinical Global Impression - Severity (CGI-S) scale. Safety will be evaluated by monitoring adverse events and changes in clinical laboratory results, including prolactin levels; physical examination results; tardive dyskinesia will be rated using the Abnormal Involuntary Movement Scale (AIMS), akathisia will be rated according to the Barnes Akathisia Rating Scale (BARS), extrapyramidal symptoms will be evaluated using the Simpson-Angus Rating Scale (SAS); electrocardiogram (ECG); vital sign measurements; and concomitant therapy. ER OROS paliperidone (6 or 12 mg) or IR paliperidone (2 or 4 mg) oral dosage administered daily for 7 days (Day -7 to -1), followed by i.m. injections of paliperidone palmitate (either 50 mg eq. or 100 mg eq.), or placebo on Days 1, 8, and 36 of the study.
