Efficacy, Safety, and Tolerability of Eslicarbazepine Acetate in the Recurrence Prevention of Bipolar I Disorder

26 de febrero de 2014 actualizado por: Bial - Portela C S.A.

Extension Study to Investigate the Efficacy, Safety, and Tolerability of Eslicarbazepine Acetate (BIA 2-093) in the Recurrence Prevention of Bipolar I Disorder

This was an extension study consisting of 2 parts. In Part I, all participants received open-label treatment with BIA 2-093 900 mg once daily for 2 weeks. Part II followed a double-blind, parallel-group design in which participants were randomly assigned to treatment with BIA 2-093 300 mg, 900 mg, or 1800 mg once daily. Patients stable in remission continued double-blind therapy until approximately 6 months after the last patient entered Part II.

Descripción general del estudio

Descripción detallada

The occurrence of a new manic/depressive episode was considered a treatment failure, and the patient was discontinued from the study. At the end of Part II, 6 months after last patient enrolled and after no longer than approximately 15 months, if patients were still in remission and the investigational product was well-tolerated, patients had the option to enter long-term open-label treatment at the same dosage as used in Part II until a new episode occurred, until marketing was authorized, or until clinical development of BIA 2-093 in the recurrence prevention indication was discontinued. If patients did not enter long-term treatment, an established recurrence prevention medication was prescribed, and BIA 2-093 was tapered off (patients assigned to 1800 mg had the daily dose decreased to 900 mg for 6 days; those assigned to 900 mg or 300 mg received placebo for 6 days).

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Proportion of Patients Who Showed no Worsening According to the Clinical Global Impression - Bipolar Version (CGI-BP) Scale (Intent-to-Treat Population)
Periodo de tiempo: 6 months
The CGI-BP scale is a modification of the CGI scale, which provides a means of assessing severity and treatment-related improvement in manic and depressive domains reflecting clinically relevant degrees of change. The concept of improvement refers to the clinical distance between the individual's current condition and that prior to the start of treatment. The scale for 'severity of illness' measures mania, depression and overall illness on a 7 point scale from 1 ('normal, not ill') to 7 ('very severely ill'). The scale for 'change from preceding phase' and 'change from worst phase' measures mania, depression, and overall illness on an 8-point scale from 1 (very much improved) to 8 ('not applicable'). If the patient, in 'change from preceding phase', at any visit during the double-blind, has a score of 5, 6, or 7 in any of 3 categories (mania, depression, or overall bipolar illness), then the illness will be considered to have worsened.
