The coronavirus (SARS-CoV-2) is a new strain of coronavirus found in human in 2019, whichcauses epidemic worldwide. A study found that the increase in hyaluronic acid levels isclosely related to the clinical symptoms of COVID-19, including pulmonary ground glasslesions, lymphocytopenia, immune response and cytokine storms, systemic vasculardiseases, thrombotic coagulation disorders, which suggests that hyaluronic acid could bean important target for COVID-19 treatment and could improve the clinical symptoms ofCOVID-19 patients.The results from a recent clinical trial recruited 144 patients with COVID-19 show thatthe inhibitor of hyaluronic acid synthesis, hymecromone, can significantly improveclinical symptoms, such as lung lesions and lymphocytopenia in COVID-19 patients.Therefore, hymecromone has the potential to become one of the options of COVID-19treatment.This study is a single-center, randomized, parallel controlled, double-blind clinicaltrial designed to evaluate the efficacy and safety of Hymecromone tablets in subjectsaged 18-90 years (with boundary values) with a confirmed mild or moderate form ofCOVID-19 infection. The aim of this study is to optimize the program of the combinationof hymecromone in the treatment of COVID-19 to improve the therapeutic effect.
