Therapeutic Study to Evaluate the Safety and Efficacy of DW-MSC in COVID-19 Patients

연구 개요

This is a phase 1 clinical trial to verify the safety and efficacy of DW-MSC in COVID-19 patients. A total of 9 subjects are randomly allocated. Subjects who meet the final inclusion and exclusion criteria are randomized to the test groups (low-dose group and high-dose group) or control group (placebo group) in a ratio of 1:1:1. Subjects assigned to the test groups were administered intravenously once with 5 x 10\^7cells of DW-MSC for the low-dose group or 1 x 10\^8cells for the high-dose group after registration. Subjects assigned to the control group were administered with placebo in the same manner as the test drug (DW-MSC). At this time, all of the existing standard co-treatment are allowed. DW-MSC is adjunct therapy to standard therapy. This clinical trial is a double-blind trial, in which a randomized method will be used. To maintain the double-blindness of the study, statistician who do not participate in this study independently generate randomization code. Subjects will be randomized to the test groups (low-dose group and high-dose group) or the control group (placebo group) in a 1:1:1 ratio. After the completion of the trial, the randomization code will be disclosed after unlocking the database and unblinding procedures. Follow Up period: observed for 28 days after a single administration
