Trial Outcomes & Findings for Efficacy and Safety of Eslicarbazepine Acetate (BIA 2-093) in Acute Manic Episodes Associated With Bipolar I Disorder (NCT NCT01824602)

NCT ID: NCT01824602

Last Updated: 2014-03-27

Results Overview

The YMRS is used to assess disease severity in patients who have been previously diagnosed with mania and it has proven psychometric properties through 11 item multiple-choice diagnostic questionnaire and the total score is determined from the summation of each 11 individual scores (and can range from 0 - 60) based on the patient's subjective feedback of his clinical condition over the previous 48 hours. A higher score indicates a worse rating for symptoms related to mania. At every visit throughout the study, investigators administered the YMRS. The results of the primary analysis of efficacy were calculated using Analysis of covariance (ANCOVA) with Last Observation Carried Forward (LOCF). Primary variable is presented through ANCOVA results for absolute change in YMRS total score from baseline (V2) to end of treatment (V7). A responder has at least 50% improvement (reduction) in the YMRS total score or has a total score of less than 12 points at the end of treatment period.

Participant Flow

STUDY DATES: From: 28 Feb 2006 To: 13 Nov 2006 Study centers: 25 study centers in Europe, South Africa and South America: 7 centers in Croatia, 6 centers in Spain, 6 centers in Argentina, 1 center in Chile and 5 centers in South Africa.

Patients who met the selection criteria at randomisation visit (V) (V2, Day 1) were randomised to 1 of 4 treatment groups: 600, 1200, or 1800 mg eslicarbazepine acetate, or placebo. Patients started the assigned treatment on Day 1 and were followed for up to 3 weeks.

PRIMARY outcome

Timeframe: baseline and 3-week

Population: The ITT efficacy population of 37 patients consisted of all randomised patients who received at least one dose of investigational product and at least 1 post-baseline YMRS assessment. If a patient discontinues before the end of the 3-week treatment period then the last observation will be carried forward (LOCF).

The YMRS is used to assess disease severity in patients who have been previously diagnosed with mania and it has proven psychometric properties through 11 item multiple-choice diagnostic questionnaire and the total score is determined from the summation of each 11 individual scores (and can range from 0 - 60) based on the patient's subjective feedback of his clinical condition over the previous 48 hours. A higher score indicates a worse rating for symptoms related to mania. At every visit throughout the study, investigators administered the YMRS. The results of the primary analysis of efficacy were calculated using Analysis of covariance (ANCOVA) with Last Observation Carried Forward (LOCF). Primary variable is presented through ANCOVA results for absolute change in YMRS total score from baseline (V2) to end of treatment (V7). A responder has at least 50% improvement (reduction) in the YMRS total score or has a total score of less than 12 points at the end of treatment period.
