Clinical Trial Summary

To determine if an high intensity ketamine with ECT rescue (HIKER) approach for treatment resistant depression will: 1) reduce patient suffering by hastening disease remission, 2) have fewer side effects, 3) reduce the need for ECT, and 4) be preferred by most patients. Half of participants will be randomized to the HIKER arm and receive high intensity ketamine treatment for eight consecutive days, and the other half will be assigned to the ECT with ketamine anesthesia (EAST) arm and receive 8 ECT treatments (2-3 treatment/week)

Description:

Major depressive disorder (MDD) is a common psychiatric illness that will affect at least 15% of the population. The burden of MDD is staggering, considered by the World Health Organization to be the leading cause of disability in developed countries for people aged 15-44. Oral antidepressant therapy for MDD is notoriously ineffective. At least 3 weeks of treatment is usually required to achieve response rates that rarely exceed 40% (only 10% better than placebo); furthermore, treatment can be complicated by serious side effects serious (e.g. falls, weight gain) including increased suicidality. Up to 15% of patients will eventually be diagnosed as having treatment-resistant depressions (TRD), defined as the failure to respond to at least two antidepressants from different pharmacologic classes after adequate treatment duration at therapeutic dosages. The gold standard therapy for TRD is electroconvulsive therapy (ECT) with general anaesthesia (GA), which produces rapid antidepressant effects after only a few sessions. Propofol is the traditional anaesthetic agent used in GA for ECT, although recently this research group showed that ECT with ketamine as the primary anaesthetic produced faster depression remission compared to ECT with propofol. Despite its efficacy, ECT is associated with considerable problems. More than 10% of patients will experience amnesia and confusion, which can persist for weeks. These cognitive side effects limit the frequency of ECT treatments to two or three times per week. There is also a risk of rare but devastating cardiorespiratory adverse events, at least part of which can be attributed to the need to induce chemical paralysis (for safety) and administer opioids (for pain control) during ECT with GA. Lastly, ECT requires specialized psychiatric expertise, dedicated resources, specially trained nurses, and an anaesthesiologist - requirements that are both costly and not readily available in many settings. In contrast to ECT, daily short-acting anaesthesia, including ketamine, is well tolerated. A recent study found that only three treatments of intravenous ketamine produced a greater early improvement in depression scores compared to ECT under non-ketamine-based GA. This suggests a possibility of achieving early disease remission in TRD with ketamine-only infusions while avoiding the safety risks and treatment delays associated with ECT under GA. The efficacy, feasibility, and improved side-effect profile of frequent successive ketamine treatments suggest it may be the preferred treatment for TRD compared to ECT with ketamine-based GA. There may, however, be a small subgroup of TRD patients who do not respond to ketamine alone and require ECT, although with a daily treatment regimen, ketamine non-responders could be quickly identified and given a standard course of ECT. The researchers propose that a treatment protocol of daily High Intensity Ketamine with ECT Rescue (HIKER) will be superior to ECT Therapy with ketamine anesthesia standard therapy (EAST) in facilitating early disease remission, while at the same time yielding similar overall remission rates by allowing ketamine non-responders to be quickly identified and given ECT.
