A Safety and Efficacy Study of Hymecromone Tablets for the Treatment of Patients With COVID-19.
Study Details
Study Description
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.

Outcome Measures
Primary Outcome Measures
- The proportion of subjects who developed disease progression. [Within 28 days after initial treatment.]
To compare the proportion of subjects in the experimental group and the control group who developed disease progression within 28 days after initial treatment.
Secondary Outcome Measures
- The incidence of adverse events and serious adverse events. [The whole test process.]
To compare the incidence of adverse events and serious adverse events related to the study treatment in the experimental group and the control group.
- The time gap of COVID-19 virus clearance. [From the beginning of the research to the negative report of COVID-19 nucleic acid.]
To compare the time of virus clearance by COVID-19 virus tests in the experimental group and the control group.
- The clinical recovery time of the COVID-19 virus infection-related symptoms. [From the beginning of the research to the disappearance of clinical symptoms.]
To compare the clinical recovery time of the COVID-19 virus infection-related symptoms in the experimental group with the control group.
- The change of the serum hyaluronic acid. [Between baseline and the end of study observation.]
To compare the serum hyaluronic acid level between baseline and the end of study observation of all subjects in the experimental group and the control group.
