Summary

This trial will help determine if the levels of GABA and glutamate in the brain are associated with remission from depression after ketamine treatment.

Who is the study for?
This trial is for adults aged 18-65 with major depressive disorder or bipolar depression, who have not responded to at least two previous treatments. They must score ≥15 on the PHQ-9 depression scale and be able to understand the study's requirements. Exclusions include a BMI >40, certain medication use, recent ketamine treatment for depression, specific medical conditions like GERD or brain injury, and any active substance abuse.
What is being tested?
The study tests if changes in ACC GABA and glutamate levels in the brain after taking ketamine are linked to remission of depression symptoms. It also looks at whether these changes correlate with metabolite levels in the body. Participants will receive ketamine infusions and undergo MRS imaging.
What are the potential side effects?
Ketamine can cause side effects such as disorientation, dizziness, nausea, increased blood pressure and heart rate shortly after infusion. Long-term side effects may include cognitive issues or bladder problems but are less common.

Study Objectives

Study objectives can provide a clearer picture of what you can expect from a treatment.
Primary study objectives
To evaluate a correlation between percent change in ACC GABA and Glutamate/Glx levels (baseline to peak) with a change in MADRS (baseline to 24 hours).
To evaluate percent change in the anterior cingulate cortex (ACC) GABA and Glutamate (baseline to peak) during a 40-minute IV ketamine infusion and remission (MADRS ≤9) at 24 hour
Secondary study objectives
To compare the percent change in peripheral GABA/Glutamate levels between remitters and non-remitters
To evaluate the correlation between percent change in peripheral GABA and glutamate levels with a change in MADRS scores.

Awards & Highlights

All Individual Drugs Already Approved
Therapies where all constituent drugs have already been approved are likely to have better-understood side effect profiles.
No Placebo-Only Group
All patients enrolled in this study will receive some form of active treatment.
