What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores how ketamine, combined with therapy, can assist people with treatment-resistant depression (TRD). TRD is a challenging form of depression that does not improve with standard treatments and is associated with higher suicide rates. The study examines whether ketamine can enhance brain flexibility and openness, potentially improving mental health and reducing suicide risk. People with TRD who have tried at least two antidepressants without success in the past two years may be suitable candidates for this trial. Participants will undergo brain scans, attend therapy sessions, and receive doses of ketamine. As a Phase 2 trial, this research focuses on measuring the treatment's effectiveness in an initial, smaller group, offering participants a chance to potentially benefit from an innovative approach.

Will I have to stop taking my current medications?

You may need to stop taking certain medications that could interact with ketamine, such as stimulants and some antidepressants. Your current medications will be reviewed for potential interactions before you can join the trial.

Is there any evidence suggesting that ketamine-assisted psychotherapy is likely to be safe for humans?

Research has shown that ketamine is generally safe and well-tolerated for people with treatment-resistant depression (TRD). In studies involving many patients, ketamine proved both safe and effective. However, like any treatment, side effects can occur.

Some individuals may experience a dissociative state, feeling disconnected from reality. This can include vivid dreams or a sensation of time slowing down. These effects typically do not last long and cease after treatment ends.

The treatment under consideration combines ketamine with therapy, which has been shown to reduce depressive symptoms more effectively than ketamine alone. Notably, the FDA has approved a form of ketamine, called esketamine, for treating TRD, supporting its safety.

For any concerns, consult the study team or your doctor. They can help determine if this treatment is suitable for you. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for depression?

Ketamine-Assisted Psychotherapy is unique because it targets treatment-resistant depression through a novel mechanism of action. Unlike standard treatments such as SSRIs or cognitive behavioral therapy, which can take weeks to show results, ketamine acts rapidly, potentially offering relief within hours. Researchers are excited about this treatment because ketamine is believed to modulate glutamate, a neurotransmitter in the brain, offering a new pathway for alleviating depressive symptoms for those who haven't responded to traditional therapies.

What evidence suggests that ketamine-assisted psychotherapy might be an effective treatment for treatment-resistant depression?

Research has shown that ketamine-assisted therapy, which participants in this trial will receive, can significantly benefit individuals with treatment-resistant depression. Studies have found that ketamine can reduce depression symptoms by about 49% in these patients. It acts quickly, offering fast relief, which is crucial for those with severe depression. This therapy also promotes brain adaptation and change in areas related to depression, potentially enhancing emotional processing. Furthermore, when combined with talk therapy, ketamine's positive effects can last longer, improving mental health and reducing anxiety and depression symptoms. ^{1 3 6 7 8}

Are You a Good Fit for This Trial?

This trial is for individuals with treatment-resistant depression, which means their depression hasn't improved after trying other treatments. Participants will need to visit the facility multiple times and undergo MRI brain scans, psychotherapy sessions, ketamine doses, and complete online surveys.

What Are the Treatments Tested in This Trial?

Interventions

• Ketamine-Assisted Psychotherapy

Trial Overview

The study tests if ketamine can improve brain plasticity in the frontolimbic region (linked to depression) and increase psychological flexibility. It combines ketamine injections with psychotherapy to see if this approach effectively treats TRD over a two-month period.
