Criterion for Admission into Study Period IV [23] The patients that are enrolled in the study are those that suffer syndromic and/ or symptomatic relapse (YMRS ? 15 and/ or HAMD ? 15) from the treatment arm that discontinued treatment with olanzapine. 6.A.5.

| Main Objective: The main objective of this study is to compare the efficacy in the prevention of relapse to manic, depressive, or mixed episodes in two groups of bipolar I patients who responded to open-label treatment with olanzapine in mono or co-therapy and who are in symptomatic and syndromic remission at the time of entering the study. The first group will receive olanzapine for a period of 3 months following inclusion into the study; the second group will receive olanzapine for 12 months. Relapses will be evaluated in terms of the total YMRS (Young Mania Rating Scale) and HAMD-21 (the 21-item Hamilton Depression Rating Scale) scores.;Secondary Objective: ·To compare the efficacy of maintaining olanzapine for 3 months versus maintaining it for 12 months in the improvement of symptomatology in patients who had achieved remission. To compare the efficacy of long-term treatments by means of longitudinal assessment using the general subscale of the CGI BP M To evaluate the safety of maintenance treatment with olanzapine and other coadjuvant medication in both groups of follow up. To determine the impact on resource utilization the two treatment groups have To assess the differences between groups with respect to improvement in functioning and quality of life. To understand the degree of impact the illness provokes in relatives or caregivers throughout the study. The self-report scale of family burden (Escala de Carga Familiar ? ECF) will be used for this purpose;Primary end point(s): The main efficacy measures to be used in this study are the YMRS and HAMD 21 scales. Special attention will be given to the inclusion of the criterion of hospital admission within the framework of psychopathological relapse. The Young Mania Scale is used to assess severity of manic symptoms and consists of 11 items. Items 5, 6, 8, and 9 are rated on a scale of 0 to 8, with 8 being the score that indicates the greatest symptom severity possible. The remaining items are rated | — |
Secondary
| Measure | Time frame |
|---|---|
| Timepoint(s) of evaluation of this end point: 2 years;Secondary end point(s): The Total BPRS is a routinely used scale. Its use is aimed at evaluating psychopathology. It contains 18 items that are given a score of 1 to 7 according to severity. However, in the analysis, the scale will be rated from 0 to 6. The total score will vary between 0 and 108. The BPRS positive subscale is made up of items 2, 3, 6, and 23 from the global scale and it has a range of 0 to 24. It is useful for measuring positive psychotic symptoms. The CGI BP S Scale measures the severity of the mental disorder adjusted for bipolar disorder. It assesses manic and depressive symptoms, as well as the disorder in general at the time of evaluation. Scores fall within a range of 1 to 7, with 7 being the score that indicates the greatest degree of severity. The CGI BP M scale enables a longitudinal assessment of the disease to be performed. It is especially useful for evaluating the efficacy of long-term treatments. It is comprised of three subscales: mania, depression, and general. The first two refer to the patient?s acute situation and examine how the patient has been since his/ her last evaluation. The general subscale refers to the longitudinal status of the patient since starting the study medication. The first time this subscale is administered, prior to admission into the study, the time period under consideration will be the year before evolution if the time of introduction of the new treatment is unknown. This scale differs from the CGI BP S in that the correlation between the three subscales may not necessarily be congruent, so that a patient who has a low score on the mania and/ or depression subscale may have a high global score if he/ she presents a rapid cycling course of the illness during the previous year. | — |
