What this Trial Is About

The COVID-19 pandemic has swept across the globe, affecting millions of individuals with varying degrees of severity. While many individuals recover from the acute phase of the infection, a significant proportion continue to experience persistent and debilitating symptoms long after the initial SARS-CoV-2 infection. This condition, known as Long COVID (LC) or sometimes referred to as Post-COVID Condition (PCC) or post-acute sequelae of COVID-19, has emerged as a complex multisystemic condition and challenging health issue, affecting approximately 10% of COVID-19 patients. Various symptoms characterize LC, including fatigue, sleep disturbances, cognitive impairment, and mood disturbances. Some of the symptoms are shared with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) - a condition marked by debilitating fatigue and a host of other symptoms without precise biomarkers or objective tests for diagnosis. Effective LC treatments remain elusive and LC patients continue to grapple with persistent symptoms that significantly impact their quality of life. Given the lack of effective treatments, it is imperative to explore novel therapeutic approaches that may alleviate the suffering of this patient population.
