Efficacy and Safety of Ramelteon Sublingual as Adjunctive Therapy for Maintenance Treatment of Bipolar I Disorder

Phase 3

Terminated

• Conditions: Bipolar Disorder
• Interventions: Drug: Placebo; Drug: Ramelteon SL

• Registration Number: NCT01467713
• Lead Sponsor: Takeda

Brief Summary

The purpose of this study is to determine the efficacy and safety of ramelteon, once nightly before bedtime (QHS), sublingual (SL), in the maintenance treatment of Bipolar I Disorder in adult patients.

Detailed Description

TAK-375SL (ramelteon sublingual formulation) is being developed by Takeda Pharmaceutical Company Limited as an adjunctive treatment in the maintenance therapy of bipolar I disorder.

Participants will be seen twice a month for the first two months and then once every month up to the end of the 9-month treatment period. Participants who complete the 9-month treatment period will have a follow-up visit approximately seven days after the last visit. A safety followup phone call will be made 30 days after completion of the 9-month treatment period.

Based on the recommendation of the Independent Data Monitoring Committee which determined that the study data had met pre-determined criteria for futility, Takeda has made a decision to terminate the study. No safety concerns were identified by the Independent Data Monitoring Committee

Secondary Outcome Measures

Name	Time	Method
Time From Randomization to Relapse Due to Depression	Randomization to Month 12 double-blind treatment period	Relapse due to depression determined by any of the following criteria during the 12-month double-blind treatment period: PI judgment, MADRS ≥16, psychiatry hospitalization, ECT or any psychotropic medication change prescribed for the treatment of depressive episodes.
Time From Randomization to Relapse Due to Depression From PI Judgement and/or MADRS ≥16	Randomization to Month 12 double-blind treatment period	The time from randomization to relapse event during the 12 month double-blind treatment period due to depression, determined by the PI judgement and/or a MADRS score ≥16. MADRS is a 10-item clinician rated scale to measure overall severity of depressive symptoms (i.e., apparent sadness, reported sadness, inner tension, etc.) rated on a 7-point Likert scale from 0 (normal) to 6 (most abnormal) with a total score range from 0 to 60. Higher scores indicate greater severity of symptoms.
Time From Randomization to Study Withdrawal for Any Reason	Randomization to Month 12 double-blind treatment period	The time from randomization to study withdrawal during the 12 month double-blind treatment period. Withdrawal includes pretreatment event/adverse event; liver function test abnormalities; major protocol deviation; lost to follow-up; voluntary withdrawal; study termination; pregnancy; lack of efficacy; participant has a depressive, mania/hypomania or mixed episode; is hospitalized for psychiatric reasons; receives electroconvulsive therapy for bipolar disorder; receives any psychotropic medication change prescribed for the treatment of depression, mania/hypomania or mixed episodes; or any other reason.
Quality of Life, Enjoyment and Satisfaction Questionnaire Short Form (Q-LES-Q-SF) Total Score	Baseline and Months 1, 2, 3, 4, 5, 6, 7, 8, 10 and 12	Q-LES-Q-SF is a self-administered 16-item questionnaire to assess the degree of enjoyment and satisfaction experienced by patients in various areas of daily functioning. It includes 30 items across five subscales (daily activities, clothing, diet/food habits, relationship, psychological well-being and distress), scored on a 6-point Likert scale with subscale and total score ranging from 0 (none) to 5 (all the time). For reporting purposes, the scores are reversed and higher scores reflect improved quality of life and positive changes relative to baseline indicate improved quality of life.

YMRS is a 11 item scale with four items scale to assess manic symptoms, rated on a scale from 0 (symptom not present) to 8 (symptom extremely severe), with 7 items rated on a scale from 0 (symptom not present) to 4 (symptom extremely severe) with higher scores reflecting greater levels of mania. The YMRS total score is calculated as the sum of the 11 individual item scores and ranges from 0-60.

Time From Randomization to Relapse Due to Mixed Episode	Randomization to Month 12 double-blind treatment period	Relapse due to Mixed episode is determined by PI judgement and/or MADRS score ≥16 and YMRS total score ≥16. MADRS is a 10-item scale that measures overall severity of depressive symptoms rated on a 7-point Likert scale from 0 (normal) to 6 (most abnormal) with a total score range from 0 to 60. YMRS is a four item scale to assess manic symptoms, rated on a scale from 0 (symptom not present) to 8 (symptom extremely severe), with 7 items rated on a scale from 0 (symptom not present) to 4 (symptom extremely severe).
