Clinical Trial Summary

A phase1/2, open label, dose escalation, safety and early efficacy study of CAStem for the treatment of severe COVID-19 associated with or without ARDS.


Clinical Trial Description

CAStem is an injectable product composed of immunity- and matrix-regulatory cells (IMRCs), also named M cells, differentiated from clinical-grade human embryonic stem cells (hESCs) will be expanded, harvested, and formulated at a concentration of 50 x 10^6 cells/mL. CAStem will be cryopreserved and transported to clinical site using liquid nitrogen vapor shipping vessels (< -150ºC). Prior to injection, CAStem will be thawed to liquefy quickly, and then reconstituted in normal saline.In the present study, the intravenous infusion dose of CAStem will be 3, 5 or 10 million cells/kg. ;
