Specific Health ConditionDepression
The aim of this study is to determine if a course of ketamine is an effective therapy for depression. The study will also determine if repeated ketamine doses: 1) are safe, tolerable and feasible in outpatient settings; 2) provide sustained antidepressant benefits; 3) improve anxiety, suicidal ideation and health related quality of life; 4) are a cost effective treatment. 200 participants will be recruited across 6 sites in Australia (Black Dog Institute, Sydney; Royal Prince Alfred Hospital, Sydney; Monash Alfred Psychiatry Research Centre, Melbourne; South Eastern Private Hospital, Noble Park; Royal Adelaide Hospital, Adelaide; Gold Coast University Hospital, Gold Coast) and 1 in New Zealand (Dunedin, Otago). The study is a randomised controlled trial. Participants will be randomised to receive repeated doses of ketamine or a comparator treatment. For all participants, a follow-up assessment after finishing the randomised controlled phase will assess eligibility for an open label extension phase. All participants will be followed up after exiting the trial to assess treatment effects.
