Clinical Trial 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.

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.

After careful consideration and in consultation with the Data Monitoring Committee, Takeda has made the decision to terminate this study. This was a business decision. There were no safety concerns.

Higher scores indicate greater severity of symptoms.	Randomization to 9 months double-blind treatment period	No
Secondary	Time from Randomization to Relapse in Mania/Hypomania	Relapse in mania/hypomania is determined by the primary investigator (PI) judgement and/or a YMRS total score =14. 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.	Randomization to 9 months double-blind treatment period	No
Secondary	Time from Randomization to Relapse in Mixed Episode	Relapse in Mixed episode is determined by PI judgement and/or MADRS score =16 and YMRS total score =14. 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.

Secondary	Quality of Life, Enjoyment and Satisfaction Questionnaire Short Form (Q-LES-Q-SF) total score at Month 1, 2, 3, 4, 5, 6, 7, 8 and Month 9.	Q-LES-Q-SF is a self-administered 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).
