Clinical Trial Summary

Ketamine has been safely used for induction and maintenance of anesthesia for decades and more recently has been used for chronic pain. Ketamine is a noncompetitive, high-affinity antagonist of the N-methyl-D-aspartate type glutamate receptor, with additional effects on dopamine and μ-opioid receptors. During the last 9 years several uncontrolled reports have been published, showing a rapid and impressive effect of ketamine in TRD patients (Berman, Cappiello et al. 2000; Zarate, Singh et al. 2006; Mathew, Murrough et al. 2010; Aan Het Rot, Zarate et al. 2012; Mathew, Shah et al. 2012; Murrough, Iosifescu et al. 2013). Recently three placebo-controlled trials showed that a single dose of sub-anesthetic, (0.5 mg/kg) slow intravenous (IV) ketamine improves depressive symptoms dramatically. Across studies, a clinically significant antidepressant response was maintained for up to 72 hours in 12 of 25 patients. Nonetheless, all but two patients relapsed <2 weeks post-ketamine (Zarate, Singh et al. 2006; aan Het Rot, Zarate et al. 2012). Rot et al. showed that repeated IV ketamine infusions prolongs the duration of improvement.

The investigators believe that the data presented above allows us to provide ketamine treatment here in the Sheba Medical Center for TRD patients.

Clinical Trial Description

Major depressive disorder (MDD) is one of the leading causes of disability worldwide (Collins, Patel et al. 2011). A substantial proportion of patients do not achieve adequate remission despite multiple antidepressant trials and augmentation strategies (Rush, Trivedi et al. 2006; Weissman, Pilowsky et al. 2006). Treatment-resistant major depression (TRD) is defined as an insufficient response to at least two adequate antidepressant trials (Rush, Trivedi et al. 2006). Many of these patients are referred to previous somatic treatment e.g. electroconvulsive therapy (ECT), rapid Transcranial Magnetic Stimulation (rTMS) and Vagal Nerve Stimulation (VNS), all of which have serious disadvantages and/or limited efficacy.

Ketamine has been safely used for induction and maintenance of anesthesia for decades and more recently has been used for chronic pain.
