The lead Phase I safety phase will further confirm the safety profile of UMSC01 in 5 COVID-19 patients each at two dose regimens and placebo.~To start the Phase IIa study, data analysis will be performed as soon as the 21-day treatment period has been completed in the three groups. With considerations of the pandemic status and clinical practice, only one of the two active treatment groups will be selected to complete the Phase IIa study, which will recruit 60 patients.
This study is to explore the safety and efficacy of using UCMSC01 in patients with COVID-19 infection via IV stem cell administration. The novelty of the current UMSC01 treatment is the single IV infusion of UMSC01 to the worldwide emergency outbreaks of COVID-19. We hypothesize that sufficient UMSC01 retention in lung may modulate the systemic inflammatory responses.
