Treatment Resistant Depression

About this study

Depression is a common condition, with serious negative effects on the health and quality of life of those affected. While there are currently various medications which attempt to treat depression, they often take a long time to begin to work and do not work at all for many people. There is therefore a need for new treatments which work quickly and effectively. One such medication is called ketamine. Studies have shown that ketamine can treat symptoms of depression quickly. This quick action sets ketamine apart from many antidepressants that take weeks to show noticeable effects. One way that it may do this is by creating a transient sense or feeling of being separated from reality, such as seeing or hearing things that are not really there. Another way to create these same feelings is with virtual reality (VR), where a person can feel as though they are entering a 3-dimensional virtual computer-generated world by wearing a special headset or goggles with a computer inside. In this study, all participants will receive standard ketamine treatments for depression. Half of the participants will also use a VR headset while receiving the ketamine treatments to see if ketamine and VR acting together provide a better treatment for symptoms of depression than ketamine alone. This is a small pilot trial. The main purpose of this trial is to learn if it is possible to run a larger clinical trial comparing "ketamine and VR" with "ketamine alone", for adults with treatment-resistant depression. The researchers will study this by seeing how many participants take part in the study within 1-2 years, and how many complete the study treatments and tests. The researchers will also compare the two study groups to see if "ketamine and VR" provide a better treatment for symptoms of depression than "ketamine alone".

Interventions

Drug: Ketamine — Standard-of-care ketamine treatment in the outpatient setting: 0.5 mg/kg IV infused over 45 minutes (with monitoring up to 90 minutes) per session, with 2 sessions per week for 2 weeks (total 4 treatments).
Device: Oculus VR headset — Immersion in 45 minutes of virtual environments using the Oculus VR headset during each ketamine infusion.

Primary outcomes

Feasibility - Number of Participants who Complete at least 90% of Study Follow-ups (From enrolment until the end of follow-ups at 3 months)
Feasibility - Time Required to Complete Enrolment (At the time of enrolment)
