Schizophrenia Clinical Trial
Official title:
A Phase 3, Short-Term, Multicenter, Placebo-Controlled, Randomized Withdrawal Study of LY2140023 Monohydrate in Patients With DSM-IV-TR Schizophrenia
The purpose of this study is to determine whether or not people with schizophrenia who take LY2140023 become physically dependent on it, and experience a series of symptoms such as craving to have the drug when they stop using it. This trial consists of two phases: An open-label phase consisting of up to 4 weeks and a double-blind phase consisting of up to 3 weeks.
This was a short-term, multicenter, placebo-controlled, randomized withdrawal study comparing LY2140023 with placebo in the treatment of outpatients with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR [APA 2000]) schizophrenia. Patients were male or female outpatients, 18 to 65 years of age (inclusive) at study entry, with a diagnosis of schizophrenia as defined in the DSM-IV-TR The primary objective of this study was to assess whether LY2140023, when administered in an acute-treatment trial with flexible doses (40 mg or 80 mg) BID, was associated with physical dependence, as measured by the occurrence of withdrawal symptoms during a randomized withdrawal phase in patients diagnosed with schizophrenia. Assessment was to be based on a comparison of randomized LY2140023-treated patients with those on placebo, as measured by the maximum of the 3-day moving average of the patient's total score on the Discontinuation Symptom Checklist-Modified Rickels (DSCMR). ;
