Brief summary

Aims The primary aim of this study is to investigate the efficacy of adjunctive mangosteen pericarp 1000mg/day for the treatment of bipolar depression using a 24 Week randomised, placebo controlled trial. The primary outcome measure will be the change in severity of mood symptoms, measured using the Montgomery Asberg Depression Rating Scale (MADRS). Secondary outcomes include global psychopathology, substance use, functioning, quality of life, and safety and tolerability data. A follow-up interview will be conducted 4 weeks posttreatment to determine any outcomes following cessation of the trial agent. Method We plan to recruit a total of 150 participants aged 18+years with moderate to severe bipolar depression (having a DSM5 diagnosis of bipolar I or II or bipolar disorder not elsewhere classified (NEC), determined using the Structured Clinical Interview for DSM Disorders 5 (SCID5), currently be in a major depressive episode on SCID5, and meeting criteria of a Montgomery Asberg Depression Rating Scale (MADRS) score of greater than or equal to 20. Participants will attend a screening visit to ascertain suitability and once randomized they will receive a month’s supply of either 1000mg/day of mangosteen or matched placebo to be taken in addition to their treatment as usual. Participants take two capsules per day. Participants will visit the study site at weeks 4, 8, 12, 16, 20 24 and 28 (4 weeks posttreatment discontinuation) where a battery of validated outcome measures will be administered by trained research staff. Participants will be asked to discuss their symptoms, side effects and any issues the participant would like to raise regarding the trial. Participants will be notified of which arm of the study they took part in and a summary of results at the completion of the study.

Interventions

1000mg/day of oral (2 capsules, once a day) of adjunctive Garcinia Mangostana Linn. (mangosteen) pericarp will be trialled against placebo for 24 weeks to determine the efficacy of mangosteen pericarp for the treatment of bipolar depression. Adherence will be monitored by participants returning all bottles of investigational product, including any unused capsules.
