             consent.

          -  Participants willing to discontinue all prohibited medications to meet
             protocol-required washouts prior to and during the trial period.

          -  Participants with a Diagnostic & Statistical Manual on Mental Disorders, 5th Edition

             International Neuropsychiatric Interview and a history of at least 1 previous manic
             episode with or without mixed features with manic symptoms of sufficient severity to
             require one of the following interventions: hospitalization or treatment with a mood
             stabilizer, or treatment with an antipsychotic agent. "Require" was defined as an
             intervention that occurred rather than one that was recommended.

          -  Young-mania rating scale (YMRS) score of ≥24 at screening and baseline.

        Exclusion Criteria:

          -  Sexually active male or women of childbearing potential who did not agree to practice
             2 different methods of birth control or remain abstinent during the trial and for 30
             days after the last dose of investigational medicinal product.

          -  Females who were breastfeeding and/or who had a positive pregnancy test result prior
             to receiving trial medication.

             clozapine.

          -  Participants with a history of DSM-5 diagnosis other than bipolar I disorder,
             including schizophrenia, schizoaffective disorder, major depressive disorder,

             cognitive disorders. Also, participants with borderline, paranoid, histrionic,
             schizotypal, schizoid, or antisocial personality disorder. All other current diagnoses
             must have been discussed with the medical monitor.

          -  Participants whose current manic episode had lasted for more than 4 weeks overall, or
             who had required hospitalization >21 days for the current acute episode at the time of
             the screening visit, excluding hospitalization for psychosocial reasons.

          -  Participant with manic symptoms better accounted for by another general medical
             condition or direct physiological effect of substance (for example, medication).

          -  Participants with a positive drug screen for cocaine or other illicit drugs.

          -  Abnormal laboratory test results, vital signs or electrocardiogram findings, unless
             based on investigator's judgment the findings are not medically significant or would
             not impact the safety of the participant or the interpretation of the trial results.

          -  Rapid cyclers with more than 6 episodes in the previous year.

          -  Participants with hypothyroidism or hyperthyroidism (unless condition has been

             participated in more than 2 clinical trials within the past year.

          -  Use of psychotropic medications (other than benzodiazepines) within 7 days of the
             baseline YMRS.
