To Determine Long Term Efficacy and Safety of Asenapine in Schizophrenic Patient Population (A7501012)(COMPLETED)(P05770)
Study Details
Study Description
Brief Summary
Schizophrenia is a brain disease. The condition may be associated with acute psychotic episodes and long-term disability despite remission from the acute symptoms. Current management of schizophrenia focuses on the treatment of acute symptoms as well as long-term treatment aimed at preventing relapse after patients have experienced an improvement in acute symptoms. Patients who discontinue treatment have a high likelihood of experiencing relapse within 1-2 years after an acute episode of schizophrenia. Patients who remain on antipsychotic treatment have lower rates of relapse and have milder courses of exacerbation when relapse occurs.The symptoms of schizophrenia may be due to an imbalance in chemicals in the brain, primarily dopamine and serotonin, which enables brain cells to communicate with each other. Asenapine may help to correct the imbalance in dopamine and serotonin. The purpose of this clinical trial is to evaluate the efficacy of asenapine in preventing relapse/impending relapse (hereafter referred to as 'relapse') in subjects who have been treated with asenapine for symptoms of schizophrenia for 26 weeks. In addition, to determine the safety and tolerability of asenapine for up to 1-year of treatment.

Outcome Measures
Primary Outcome Measures
- Time to Relapse or an Impending Relapse [time of first relapse up to Day 182 (double blind phase)]
A relapse or impending relapse was declared if a subject meets 1 of 3 "symptomatic relapse criteria" which were all based on a combination of the Positive and Negative Syndrome Scale (PANSS) total score or PANSS items, and Clinical Global Impression-Severity (CGI-S); or if in the opinion of the investigator, the subject's symptoms of schizophrenia had deteriorated to such an extent or the risk of violence to self or others or risk of suicide had increased so that certain prespecified measures were necessary.
Secondary Outcome Measures
- Time to Early Discontinuation for Any Reason [time of discontinuation up to Day 182 (double blind phase)]
The number of days to early discontinuation is the number of days from randomization to early discontinuation from the study for adverse event, relapse or impending relapse that was not considered an adverse event, withdrawal of informed consent, or lost to follow-up (without evidence of relapse).

Participant Flow
Recruitment Details | |
---|---|
Pre-assignment Detail | Prior to randomization, there was a 26 week open-label phase where 700 subjects received at least one dose of open-label asenapine (out of 831 initially enrolled). Only subjects who had continued stable presentation of symptoms during this phase were randomized into the double-blind phase. |

Subjects received 26 weeks of open label asenapine treatment (cross titration period up to first 4 weeks, with target dose of 10 mg twice daily by week 1), followed by asenapine 5 or 10 mg sublingual twice daily for 26 weeks in the double blind phase. | Double Blind Placebo Group. Subjects received 26 weeks of open label asenapine treatment (cross titration period up to first 4 weeks, with target dose of 10 mg twice daily by week 1), followed by matching placebo sublingual twice daily for 26 weeks during the double-blind phase. |

Adverse Events
Time Frame | Prior to randomization to the double-blind period, there was a 26 week open-label phase where 700 subjects received at least one dose of open-label asenapine (out of 831 initially enrolled). | |||||
---|---|---|---|---|---|---|
Adverse Event Reporting Description | During the first 4 weeks of the open-label period, subjects could cross titrate. The target dose of asenapine was 10 mg twice daily by week 1. Only subjects who had continued stable presentation of symptoms during open-label phase were randomized into the double-blind phase (into Asenapine or Placebo arm). Remainder of subjects were not randomized. | |||||
