Description

Inclusion Criteria:

  2. Female patients must test negative on a serum pregnancy test at the time of enrollment and agree to use medically accepted contraception throughout the study.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
To assess the superiority of olanzapine plus carbamazepine versus placebo plus carbamazepine in improving overall manic symptomatology in patients with mania associated with bipolar I disorder.
Improvement is measured by a reduction in the total score of the Young Mania Rating Scale (YMRS) from baseline to endpoint during the 6-week, double-blind treatment phase.

Secondary Outcome Measures

Outcome Measure
To compare the efficacy and safety of up to 6 weeks of double-blind, concomitant use of olanzapine plus carbamazepine to the concomitant use of placebo plus carbamazepine
Using the following assessments:
rate of response and time to response over 6 weeks of the double-blind treatment phase, with response defined as a reduction of 50% or more in the YMRS total score from baseline to endpoint.
rate of remission and time to remission of mania over 6 weeks of the double-blind treatment phase, with remission defined as a score less than or equal to 12 on the YMRS total score at endpoint
reductions from baseline to the endpoint of the 6-week, double-blind treatment phase on the Montgomery-Asberg Depression Rating Scale (MADRS) total score
reductions from baseline to the endpoint of the 6-week, double-blind treatment phase on the Clinical Global Impressions-Bipolar Version Severity of Illness Scale (CGI-BP)score
rate of switch to depression and time to switch to depression, with switch to depression defined as a baseline MADRS total score less than or equal to 12 followed by
either a post baseline MADRS total score greater than or equal to 16 over the 6 weeks of the double-blind treatment phase OR, hospitalization due to deterioration in clinical
symptoms of depression
longitudinal effects from baseline across visits of the double-blind treatment phase by comparing changes in YMRS total scores
changes in vital signs and weight, laboratory analytes, and electrocardiograms (ECGs), and the incidence and severity of TEAEs and extrapyramidal symptoms (EPS)
using the Barnes Akathisia Scale, Simpson-Angus Scale and the AIMS.
the effect of carbamazepine on the plasma concentration of olanzapine via comparison to historic oral steady-state olanzapine concentrations
the effect of olanzapine on the plasma concentrations of carbamazepine via a descriptive comparison of the two treatment groups
Additional secondary objectives are to assess the maintenance of treatment effect and safety of up to 20 weeks of open-label olanzapine-plus-carbamazepine treatment
using the following measures:
YMRS total score change from the baseline (Visit 7) to the endpoint of the open-label treatment phase.
rate of relapse to mania during the open-label treatment phase. Relapse to mania (patients who relapse to a bipolar I mania or mixed episode) is defined by the following:
patient reaches remission of mania (as defined by a YMRS score less than or equal to 12) by the endpoint of the double-blind treatment phase
patient obtains a YMRS score greater than or equal to 15 at any time during the open label treatment phase AND/OR becomes hospitalized due to deterioration in clinical symptoms of mania
rate of switch to depression during open-label treatment phase, with switch to depression defined as a baseline MADRS total score less than or equal to 12 followed by
either a postbaseline MADRS total score greater than or equal to 16 over the 20 weeks of the open-label treatment phase hospitalization due to deterioration in clinical symptoms of depression
changes in vital signs and weight, laboratory analytes, and ECGs, and the incidence and severity of TEAEs and EPS using the Barnes Akathisia Scale, Simpson-Angus Scale, and the Abnormal Involuntary Movement Scale (AIMS)
