Ketamine clinical trials, in English

Ketamine and esketamine (Spravato) studies are usually psychiatry protocols with monitoring requirements. They are not the same as recreational use. Suicidality and substance-use exclusions are common — see the official record. Search the same name on ClinicalTrials.gov.

Phase 1: testing Ketamine for Healthy

The core objective of this study is to enhance the translational potential of this electroencephalogram (EEG) biomarker by using ketamine(KET)-induced gamma potentiation as a prognostic marker of 4-week treatment outcome. Previous research focused exclusively on KET-induced gamma band potentiation (GBP) in the context of a single infusion.

Phase 3: testing Racemic ketamine for Depression

This study wants to compare the relative effectiveness, acceptability, and side effects of ketamine delivered through an IV (a drip into the arm) which is not currently FDA approved for use in the treatment of treatment-resistant depression (TRD) and Esketamine (Spravato®), taken as a nasal spray which has received FDA approval for use in the treatment of treatment-resistant depression (TRD) in the treatment of patients with treatment-resistant depression (TRD). The study will look at the following: * How well the treatment helps with symptoms of depression (effectiveness), * How comfortable and willing people are to use the treatment (acceptability), and * How well people can deal with any side effects from the treatment (tolerability).

Phase 2: testing Ketamine (0.5 mg/kg) for Critical Illness

Depressive symptoms are common among patients admitted to the intensive care unit (ICU) and may adversely affect recovery, participation in care, treatment adherence, quality of life, and outcomes after critical illness. Conventional antidepressants have limited utility for rapidly treating depressive symptoms during an ICU admission because of their delayed onset of action and potential drug interactions in medically complex patients.
