ClinConnect Summary

This clinical trial is comparing two types of ketamine treatments, called Spravato® and racemic ketamine, to see which one works better for people with treatment-resistant depression (TRD). TRD is when someone has not found relief from their depression despite trying at least two different antidepressant medications. The study will look at how effective these treatments are, how well patients accept them, their safety, and how they affect overall quality of life and costs.

To participate, individuals must be at least 18 years old and have a current episode of depression that hasn't improved with previous treatments. Participants will be randomly assigned to receive either Spravato® or racemic ketamine. They will fill out questionnaires to help researchers understand how the treatments impact their mood, any side effects, and their daily functioning. This study is currently looking for volunteers, and it’s important for potential participants to discuss their eligibility with their healthcare provider.
