Summary

A single subanesthetic dose infusion of the N-methyl-D-aspartate (NMDA) receptor antagonist ketamine has rapid and robust antidepressant effects in patients with treatment-refractory major depressive disorder (TRD). A family history of an alcohol use disorder (Family History Positive, FHP) is one of the strongest identified predictors of an improved antidepressant response to ketamine. Like ketamine, alcohol is a functional NMDA receptor antagonist. FHP is associated with differential response to both alcohol, e.g. decreased body sway and plasma cortisol, and ketamine, e.g. blunted psychotomimetic side effects. One of the primary mechanistic hypotheses for ketamine's antidepressant action is the acute intrasynaptic release of glutamate from major output neurons, e.g. cortical pyramidal cells. Preliminary clinical studies have demonstrated this acute glutamate "surge" in response to subanesthetic dose ketamine. Based on these findings, the investigators hypothesize that ketamine's enhanced antidepressant efficacy in FHP TRD subjects is, at least in part, attributable to increased glutamate release relative to TRD subjects without a family history of alcohol use disorder (Family History Negative, FHN). The investigators also hypothesize that alcohol similarly augments glutamate release in this bio- logically-enriched subgroup, which may be a more objective biomarker than family history status. To test these hypotheses, the investigators have designed a now two-site, open-label study of 21-65 year old medically and neurologically healthy, currently moderately-to-severely depressed TRD patients. In total, the investigators plan to recruit 25 FHP and 25 FHN TRD subjects. All subjects must not have a lifetime substance use disorder (except nicotine or caffeine), no lifetime history of an alcohol use disorder and socially drink. The experimental portion consists of two phases. The preliminary first phase is a medication taper (if needed) and psychotropic medication-free period. The experimental second phase comprises two pharmacokinetically-defined basal-bolus alcohol and one subanesthetic dose (0.5mg/kg x 40 minute) ketamine infusions. The first alcohol infusion will establish the pharmacokinetic profile for a subsequent alcohol infusion occurring during 7T-magnetic resonance imaging (MRI), both resting-state functional MRI (rs-fMRI) and magnetic resonance spectroscopy (MRS) to detect glutamate in the ventromedial prefrontal cortex/ventral anterior cingulate cortex (vmPFC/vACC). The ketamine infusion will also occur during 7T-MRI. The primary outcome measure is group mean change in Montgomery-sberg Depression Rating Scale (MADRS) score from pre-ketamine infusion (baseline) to one week post-infusion, where the investigators observed ketamine's greatest antidepressant effect in FHP TRD. Additional outcome measures are vmPFC/vACC glutamate change in response to ketamine and alcohol challenge based on family history status. In summary, this study will provide key mechanistic information on ketamine's improved antidepressant efficacy in a biologically-enriched subgroup. This will contribute to the systematic development of more efficacious, personalized treatments for major depression in an effort to reduce its enormous public health burden.

Description

Objective

Glutamate-based medications including the glutamate modulator ketamine result in rapid, robust and sustained (typically up to one week) antidepressant effects in randomized controlled trials in treatment-refractory unipolar and bipolar depression. Previous work by the investigators' group has demonstrated that a family history of alcohol dependence predicts a more robust antidepressant response to ketamine in both treatment-resistant unipolar and bipolar depression.

Recently-detoxified alcoholics and affected first-degree relatives display blunted psychotomimetic, cognitive and other neuropsychiatric effects when administered a subanesthetic dose of ketamine. A family history of alcoholism also predicts differential response to intravenous alcohol. Based on the prior post hoc results, the investigators seek to prospectively demonstrate that a family history of an alcohol use disorder predicts a more robust antidepressant response to ketamine. The research team will also explore potential biomarkers of ketamine's antidepressant effects in treatment-refractory depressed patients at greater risk of developing an alcohol use disorder, using physiological and neurochemical responses to alcohol.

Study Population:

21-65 year old TRD without psychotic features patients in a current major depressive episode of at least moderate severity will be recruited and enrolled in this study. All subjects must not have a lifetime substance use disorder (except nicotine or caffeine), no lifetime history of an alcohol use disorder and socially drink. All subjects must be psychotropic medication-free for at least two weeks prior to the first alcohol infusion. The targeted number of completers is 50 depressed subjects (60 signing consent to account for attrition): 25 FHP subjects [as defined by either one first degree relative or two second-degree relatives with an alcohol user disorder on the Family Interview for Genetics Studies (FIGS) and Family Tree Questionnaire (FTQ)] and 25 FHN negative subjects.

Design

This study is a now two-site, open-label protocol in psychotropic medication-free depressed subjects. This protocol consists of two phases. Phase I consists of a medication taper (if needed) and at least two week drug-free period. Phase II has three subphases: Subphase IIA (alcohol clamp infusion #1 with neurophysiological assessments), Subphase IIB (alcohol clamp infusion #2 during 7T-MRI) and Subphase IIC (subanesthetic/antidepressant dose ketamine infusion during 7T-MRI).

Outcome Measures:

The primary hypothesis/outcome measure will be mean change in MADRS total score from the pre-ketamine infusion (baseline) to 7 days post-infusion between the FHP and FHN groups. Other exploratory measures include neurophysiological responses to intravenous alcohol, glutamate) alterations during intravenous alcohol infusion and ketamine infusions, and rs-fMRI as a function of family history status.
