Iloperidone in Mixed States of Bipolar Disorder

Study Overview
=================
Brief Summary
-----------------
To assess the acute and long-term bimodal efficacy of iloperidone (IL), as an adjunct to ongoing treatment with lithium (Li) or divalproex (DIV) or lamotrigine (LAM) or any combination of the three thereof, in a group of patients with an index episode of a mixed state in BD. To assess background, baseline features, and behavioral components which characterize treatment response/non-response in the acute and long term management of MS

Detailed Description
-----------------
This is a prospective 20-week, open-label study of iloperidone added to ongoing treatment regimen with mood stabilizers (Li or DIV or LAM or any combination of these) in the acute and maintenance treatment of MS- Total number of subjects: 40. Severity of the illness and psychopathological features will be measured by the following rating scales: YMRS, MADRS, CGI-S and GAS, and the BISS . The study will monitor the safety and tolerability of the combination iloperidone plus mood stabilizers. Efficacy Measures: Primary efficacy measures include 1) Mixed effects repeat measure of change from baseline in BISS total score and, secondarily, manic and depression subscale scores. Secondary Efficacy Measures: 1) response defined as 50% reduction in YMRS and MADRS and 2) Time to intervention or discontinuation for any mood episode. Iloperidone will be initiated at 2 mg at hs on day 1 with increase to 4mg at hs on day 2, 8 mg at hs on day 3. All patients will have iloperidone titrated to receive a dosage of at least 12 mg a day. Dosages can be titrated up to 24 mg a day based on tolerability and clinical indication. Dosage of iloperidone can be reduced to 6 mg a day if patients develop side effects necessitating a reduction in the dosage

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Measure of Response by Change From Baseline to End of Study in BISS Depression and Mania Scale Scores | The Bipolar Inventory of Symptoms Scale is a reliable and valid measure which assesses Depression and Mania symptoms of bipolar disorder. There are 42 items; each item is rated on a 0-4 scale. The BISS is a clinician-rated instrument. The Scale is rated as follows: 0 Not at all Slight Mild Moderate Severe Each of the 42 items is rated separately, with a score, based on the most recent 7 day period. For Depression: Items 1-21 items of the assessment are summed up and multiplied by 4 to give a cumulative score out of 84. The higher the score, the more severe the depression. For Mania: Items 22-42 are summed up and multiplied by 4 to give a cumulative score out of 84. The higher the score, the more severe the mania. The mean is calculated from the change in score between baseline and week 20. | Baseline and 20 weeks |
