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

Ina-Respond9 enrolled

Overview

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

Patients with Covid-19 have a mortality rate of about 35 \~ 50% and currently, severe patients caused by the Coronavirus show respiratory distress. To date, the incidence rate has been more than 3 million each year; however, as the increase and globalization of the environmental pollution has been expanded, the number of patients is expected to increase due to acute diseases such as the Middle East Respiratory virus, SARS, and coronavirus. Since 2015, Daewoong Pharmaceutical intends to use stem cells for product research on rare and intractable diseases including respiratory distress. Stem cells are also called pluripotent cells or truncal cells that can convert to any organ. It is an embryonic stage undifferentiated cell that has stopped differentiating before forming a specific organ whose differentiation has not been determined and has the ability to differentiate into muscle, bone, and internal conformal body organs. There are three types of stem cells: embryonic stem cells, adult stem cells, and induced pluripotent stem cells. Daewoong Pharmaceutical intends to develop cell therapy products using mesenchymal stem cells (MSC).

Outcomes

Primary Outcomes

Incidence of TEAE* in Treatment group

Incidence of TEAE\* in Treatment group \* TEAE: Treatment-Emergent Adverse Event All adverse reactions will be organized according to System Organ Class (SOC) and Preferred Term (PT) using MedDRA (Medical Dictionary for Regulatory Activities), and the incidence of treatment-emergent adverse events will be summarized for the coded adverse reactions.

Time frame: 28 days

Secondary Outcomes

Survival rate

Survival rate is defined as the rate of subjects surviving until Day 14 and Day 28, and the number and rate of surviving subjects for each administration group is given.

Time frame: until Day 14 and Day 28

Duration of hospitalization

Duration of hospitalization is defined as the number of days in the hospital until Day 28, and descriptive statistics (number of subjects, mean, standard deviation, median, minimum, maximum) are given for each administration group.

Time frame: 28 days

Clinical improvement Ordinal scale

Clinical improvement measured by Ordinal scale change for clinical improvement from baseline to Day 14 and 28
