What this trial studies

This clinical trial investigates the use of ketamine, an NMDA antagonist, to rapidly reduce suicidal ideation in youth aged 14-30 who have recently attempted suicide. The study will enroll 62 participants who will be randomly assigned to receive either ketamine or a placebo saline infusion while admitted to inpatient psychiatric care. The treatment aims to assess the safety and efficacy of ketamine in this high-risk population, with the potential to enhance the effectiveness of collaborative psychotherapy for long-term anti-suicidal effects. Participants will receive up to six infusions over two weeks, with careful monitoring for safety and response.

Why it matters

Potential benefit: If successful, this treatment could provide a rapid and effective intervention for reducing suicidal thoughts in at-risk youth.

How similar studies have gone: Previous studies in adults have shown promising results for ketamine in reducing suicidal ideation, suggesting potential for success in this novel application for youth.
