Study 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.Check my eligibility
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.See study design
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
Outcome measures can provide a clearer picture of what you can expect from a treatment.Primary outcome measures
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 outcome measures
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.

Answered by AI
Would I be a suitable candidate for participating in this research program?
"This trial seeks 20 individuals aged between 18 and 65, with a diagnosis of involutional psychosis. In order to be eligible for the study, participants must provide informed consent, receive psychiatric treatment as either an inpatient or outpatient, score at least 15 on the PHQ-9 scale during screening and baseline assessments; have experienced failure in two prior antidepressant treatments (including pharmacotherapy over 8 weeks or 6 administrations of ECT/TMS); and pass an assessment test related to ketamine's effects."
Answered by AI
Is this clinical trial open to individuals senior in age?
"This medical experiment is open to candidates aged 18 or above and below 65."
Answered by AI
Is recruitment for the clinical trial still ongoing?
"At the moment, this medical trial is not recruiting. First posted on March 1st 2019 and last updated September 12th 2022, it has since been suspended. For those looking for other studies that are actively accepting patients, 1393 trials related to psychosis and involutional therapies are currently enrolling participants."
