Summary

This trial aims to find out which patients with TRD are most likely to benefit from a single low dose of IV ketamine to reduce symptoms quickly.

Who is the study for?
This trial is for adults with treatment-resistant depression (TRD) who have not responded to at least two different antidepressant medications and one augmentation agent. Participants must be fluent in English, able to understand the study, provide consent, and commit to using birth control if applicable. Exclusions include certain medical conditions like liver disease or recent heart attack, substance abuse issues, use of specific drugs like naltrexone, and previous ketamine therapy.
What is being tested?
The trial tests whether a single low dose of IV ketamine can quickly relieve symptoms of TRD compared to an active placebo (Midazolam). It aims to identify predictors for who will benefit most from this treatment by observing responses at 24 hours and sustained effects up to two weeks after administration.
What are the potential side effects?
Ketamine may cause side effects such as disorientation, dizziness, nausea, increased blood pressure and heart rate shortly after infusion. Long-term safety is unclear; hence the study's focus on short-term response.
