Brief Summary:
The purpose of this research study is to find out if the medication known as ketamine can help the symptoms of depression. This drug is approved by the Food and Drug Administration (FDA) but the investigators will use it for a non-FDA approved reason (depression).
Detailed Description:
The investigators will enroll 100 adults with treatment-resistant unipolar or bipolar major depression (TRD) across 7 clinical sites and provide three IV ketamine infusions (0.5 mg/kg, infused over 100 minutes) and measure their depressive symptom responses. Biomarkers will be developed using blood samples from study subjects, taken prior to (predictive biomarkers) and following ketamine treatment (change biomarkers). The investigators will begin by studying the predictive value of mechanistic target of rapamycin (mTOR) target engagement by ketamine using a white blood cell (WBC) assay for antidepressive response to ketamine (Aim 1); however, samples will be used to develop multiple blood-based biomarkers for ketamine antidepressive effects (Aim 2). The investigators will also examine the effect of combining multiple blood-based biomarkers for predicting antidepressive response to ketamine in adults with TRD (Aim 3).
Baseline WBC markers of impaired cellular energy regulation will be associated with measures of clinical response to ketamine (predictive biomarker). Changes in WBC markers of impaired cellular energy regulation will be associated with clinical response to ketamine (change biomarker).
