Covid19 Clinical Trial
Official title:
A Multi-center, Randomized, Parallel Controlled, Double-Blinded Clinical Trial to Evaluate the Effectiveness and Safety of Hydrogen-Oxygen Generator With Nebulizer for Adjuvant Treatment of Novel Coronavirus Disease 2019 (COVID-19)
This is a multi-center, randomized, parallel controlled, double-blinded clinical trial to evaluate the effectiveness and safety of Hydrogen-Oxygen Generator with Nebulizer for adjuvant treatment of COVID-19 patients. The test group is expected to be superior to the control group in the primary endpoint (percentage of subjects achieving clinical recovery at Day 7 of study treatment). Subjects in the test group will receive treatment by using Hydrogen-Oxygen Generator with Nebulizer (manufactured by Shanghai Asclepius Meditec Co., Ltd., flow rate: 3L/min) combined with conventional basic supportive treatment (symptomatic support treatment determined by the investigator based on the condition of the subjects); and subjects in the control group will receive treatment by using Medical Molecular Sieve Oxygen Generator (manufactured by Shanghai Ouliang Medical Devices Co., Ltd., flow rate: 3L/min, provided by the sponsor) combined with conventional basic supportive treatment (same with that in the test group).
Data of the following effectiveness and safety endpoints of subjects in the two groups will be collected and analyzed in this study, including of the primary effectiveness endpoint: percentage of subjects achieving clinical recovery at Day 7 of study treatment; and the secondary effectiveness endpoints: percentage of subjects achieving clinical recovery on Day 2, 3, 5, 10 of study treatment and that before discharge; percentage of subjects whose WHO Clinical Progression Scale score decreased by 1 point or more on Day 2, 3, 5, 7, 10 of study treatment and before discharge; reduction of WHO Clinical Progression Scale score on Day 2, 3, 5, 7, 10 of study treatment and before discharge; changes in COVID-19 symptom scores on Day 2, 3, 5, 7, 10 of study treatment and before discharge; total length of hospital stay; time from randomization to conversion to general COVID-19; time from randomization to conversion to mild COVID-19 disease; percentage of patients with no fever, shortness of breath and chest pain on Day 2, 3, 5, 7, 10 of study treatment and before discharge; Oxygen saturation based on finger blood samples in resting non-oxygen inhalation state; and safety evaluation variables including incidences of AEs, SAEs and device deficiencies. ;
