Long COVID clinical trials in Chicago

The SARS-CoV-2 virus causes COVID-19, which ranges from mild initial symptoms to severe multi-organ dysfunction. While some patients recover to their baseline states, others develop a long COVID, or post-acute sequelae of SARS-CoV-2 (PASC) consisting of symptoms persisting \>2-6 months post-infection. PASC symptoms include post-exertional malaise, fatigue, and heart palpitations as well as incident GI disorders, cognitive dysfunction, and arthritis. Based on prevalence/incidence studies, it is estimated that more than 30 million people in the US have ever developed PASC with 10-11% of patients or 11 million people continuing to feel symptoms to the present day10. SARS-CoV-2 vaccines are only \~32% effective against infection at 4 months post-vaccination11, only 15% effective against the development of PASC12, and only 20% of American adults have received an updated booster as of December 202313. It is therefore imperative that the scientific community make progress in identifying underlying causes of PASC to develop effective treatments. This study will identify microbial metabolites associated with PASC-mediated gut dysbiosis and establish a tractable in vitro model to test T cell-gut epithelium dynamics to develop novel bio-therapeutics for multiple post-viral conditions. This case-control study will collect biospecimens (matched stool \& blood) samples from 400 people with and without long COVID (200 participants/group) to understand how COVID-induced dysbiosis impacts symptom severity, immune suppression, and gut barrier dysfunction both ex vivo and in vitro.

Long COVID is a condition where debilitating symptoms can persist for months after a COVID-19 infection. This study aims to evaluate the effects of NE3107 on several neurological symptoms reported in people with Long COVID including difficulty concentrating or remembering things ("brain fog") and fatigue. Researchers will compare NE3107 to a placebo (a look-alike substance that contains no drug) to see if NE3107 works to treat neurocognitive and fatigue symptoms of long COVID. Participants will: * Take NE3107 or a placebo twice daily for 84 days * Visit the clinic 5 times for checkups and tests and have a follow up phone call

Growing evidence indicates that many people who have chronic post-acute sequelae of SARS-CoV-2 infection (PASC) will experience ongoing neurological and musculoskeletal impairment that can affect gait and balance. Identifying the factors contributing to these impairments and how they influence functional mobility is the first step towards creating effective evaluation and treatment protocols. In this study the investigators will examine cognition, vision, proprioception, muscle strength, gait and balance in persons with and without PASC to understand how PASC may impact functional mobility through a cognitive-sensorimotor lens. Gait and balance will be studied in environments that stress cognitive and sensory abilities. Study outcomes will be critical for the development of evidence-based Veteran Health Administration diagnostic and standard-of-care protocols to address gait and balance dysfunction in Veterans with PASC for restoring their functional mobility and independence.

The overarching goal of this study is to determine if baricitinib, as compared to placebo, will improve neurocognitive function, along with measures of physical function, quality of life, post-exertional malaise, effect of breathlessness on daily activities, post-COVID-19 symptom burden, and biomarkers of inflammation and viral measures, in participants with Long COVID.
