Arm | Intervention/treatment |
---|---|
Active Comparator: electroconvulsive therapy (ECT)
Treatments will be given 3 times a week up to a total of 9 treatments over 3 - 5 weeks. Initial ECT treatment is Right Unilateral (RUL) ultra-brief pulse at 6X seizure threshold. Seizure threshold and dose can be increased per investigator and patient discretion.
|
Procedure: electroconvulsive therapy (ECT)
ECT is a procedure done under general anesthesia where small electric currents are passed through the brain, intentionally triggering a brief seizure. Patients who have not responded to antidepressant medications may be candidates for ECT. ECT is FDA approved for treatment resistant depression. |
Active Comparator: ketamine infusion
Treatments will be given 2 times a week up to a total of 6 treatment over 3 - 5 weeks. Initial standard dose will be 0.5 mg/kg infusion over 40 min. The dose can be modified if clinically warranted per investigator and patient discretion.
|
Drug: Ketamine
Ketamine is a medication that is used as a short acting anesthetic in pediatric and adult medicine. Subanesthetic (low) doses will be given to patients via infusion in order to assess whether it helps with depression symptoms in patients who have not responded to antidepressant therapy. Ketamine is not FDA approved for this indication and its effectiveness in treatment resistant depression has not been proven. Prior studies have indicated that subanesthetic doses of ketamine may be helpful for treatment resistant depression. |
- Patient reported response to treatment [ Time Frame: Acute Study Phase (Baseline Visit to End of Treatment Visit) - approximately 3-5 weeks ]Response is defined as at least a 50% improvement in Baseline QIDS-SR-16 score at End of Treatment Visit. The End of Treatment Visit will occur 3-5 weeks after the Baseline Visit.
- Clinician reported response to treatment [ Time Frame: Acute Study Phase (Baseline Visit to End of Treatment Visit) - approximately 3-5 weeks ]Number of patients with an improvement in their Baseline MADRS score at the End of Treatment Visit. The End of Treatment Visit will occur 3-5 weeks after the Baseline Visit.
