Clinical Trial Summary

Post-acute sequelae of SARS-CoV2 (PASC), colloquially known as "long-COVID," is thought to affect between 10-30% of all COVID-19 survivors. Patients with PASC also report worsening behavioral health symptoms over time that include new-onset depression, anxiety, and even suicidal behavior. The purpose of this randomized, double-blind, controlled trial is to test the efficacy of a glutamate modulator among PASC patients suffering from new-onset or worsening of depressive symptoms.


Clinical Trial Description

While PASC symptoms have been identified in nearly every organ system, the most common symptoms include fatigue, cognitive and attention deficits (known as 'brain fog'), shortness of breath, and post-exertional malaise. New-onset depression, anxiety, and even suicidal behavior have also been reported. Symptoms of PASC can exhibit daily variation; additionally PASC frequently demonstrates a relapsing and remitting course. This is mitigated by cognitive and emotional stress, physical exertion, diet, and alcohol consumption; therefore, measuring treatment response and the course of illness over time can be challenging. While there are many ongoing trials evaluating a variety of treatments for PASC, no clear treatment has emerged; additionally, there are no published data on psychotropic medications alleviating the inflammatory response and psychiatric symptoms in PASC. Alterations in the transmission between neurons of a neurotransmitter called glutamate are an important target of pharmacotherapy for PASC. Glutamate modulators have demonstrated promise in improving depressive symptoms and suicidality and can improve cognitive functioning among patients with these symptoms. The study team has recently developed a novel design that integrates a clinical trial involving serial infusions. The current trial will evaluate the effect of a sub-anesthetic infusion on individuals with PASC and depressive symptoms who complete a randomized, double-blind, placebo-controlled pilot study conducted over 5 weeks using a cross-over and counterbalanced design. ;
