BACKGROUND: Longer-term outcome and safety data of repeated subcutaneous racemic ketamine for treatment-resistant depression (TRD) is lacking, as is knowledge of the impact of prior ketamine treatment on subsequent response. AIMS: To evaluate the effectiveness and safety of a 4-week course of subcutaneous racemic ketamine over 6 months and investigate whether prior ketamine treatment influences...
Ketamine has disputed effects on suicidal ideation scores in depressed populations. This study assessed effectiveness of ketamine in adults with treatment resistant depression, examining a secondary outcome of suicidal ideation. Phase III, double-blind, randomized, active-controlled, multicenter trial. Participants were randomized to twice-weekly subcutaneous racemic ketamine or midazolam for 4...
Ketamine is effective for treatment resistant depression (TRD); but cost-effectiveness evidence remains limited. To evaluate the cost-effectiveness of subcutaneous ketamine for TRD from health sector and societal perspectives. A cost-utility analysis alongside the KADS randomised controlled trial (RCT) involved 174 participants receiving ketamine or midazolam (active control) twice weekly for 4...
Anxiety disorders and treatment-resistant major depressive disorder (TRD) are often comorbid. Studies suggest ketamine has anxiolytic and antidepressant properties. To investigate if subcutaneous racemic ketamine, delivered twice weekly for 4 weeks, reduces anxiety in people with TRD. The Ketamine for Adult Depression Study was a multisite 4-week randomised, double-blind, active...
Background Prior trials suggest that intravenous racemic ketamine is a highly effective for treatment-resistant depression (TRD), but phase 3 trials of racemic ketamine are needed. Aims To assess the acute efficacy and safety of a 4-week course of subcutaneous racemic ketamine in participants with TRD. Trial registration: ACTRN12616001096448 at www.anzctr.org.au. Method This phase 3,...
