A Randomized, Double-Blind, Placebo-Controlled, Phase 3 Study to Evaluate the Efficacy and Safety of Once a Day, TAK-375SL as an Adjunctive Therapy to Treatment-as-Usual in the Maintenance Treatment of Bipolar I Disorder in Adult Patients

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.

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.
