This open-label, interventional trial (n=100) will investigate the effects of ketamine infusion therapy on Australian veterans with treatment-resistant depression (TRD) and post-traumatic stress disorder (PTSD). Participants will receive six initial intravenous ketamine infusions over two weeks (35–70mg/70kg per session), followed by up to six maintenance infusions every three to six weeks based on individual response.
The study, conducted by Zed3 Medical Group and the University of Queensland, aims to establish an evidence base for ketamine as a treatment for veterans with TRD and PTSD. It will assess changes in depression and PTSD symptoms, as well as suicidality and recovery, using standard psychological scales. Infusions will be administered in a hospital setting under the supervision of anaesthetists, with ongoing monitoring by nurses. Recruitment is expected to begin in February 2025 across multiple Australian states.
