Not Applicable

• Conditions: COVID-19
• Interventions: Other: Placebo; Drug: Hymecromone tablets

• Registration Number: NCT05386420
• Lead Sponsor: Shanghai Zhongshan Hospital

Brief Summary

The coronavirus (SARS-CoV-2) is a new strain of coronavirus found in human in 2019, which causes epidemic worldwide. A study found that the increase in hyaluronic acid levels is closely related to the clinical symptoms of COVID-19, including pulmonary ground glass lesions, lymphocytopenia, immune response and cytokine storms, systemic vascular diseases, thrombotic coagulation disorders, which suggests that hyaluronic acid could be an important target for COVID-19 treatment and could improve the clinical symptoms of COVID-19 patients.

The results from a recent clinical trial recruited 144 patients with COVID-19 show that the inhibitor of hyaluronic acid synthesis, hymecromone, can significantly improve clinical symptoms, such as lung lesions and lymphocytopenia in COVID-19 patients. Therefore, hymecromone has the potential to become one of the options of COVID-19 treatment.

This study is a single-center, randomized, parallel controlled, double-blind clinical trial designed to evaluate the efficacy and safety of Hymecromone tablets in subjects aged 18-90 years (with boundary values) with a confirmed mild or moderate form of COVID-19 infection. The aim of this study is to optimize the program of the combination of hymecromone in the treatment of COVID-19 to improve the therapeutic effect.
