MRG-001 is a fixed-dose combination (FDC) drug, administered as a single subcutaneous (SC) injection. Preclinical studies have demonstrated a synergistic effect of these 2 APIs in mobilizing and recruiting stem cells/immunoregulatory cells and promoting tissue regeneration in a wide variety of studies.~MRG-001 is likely to target multiple aspects of the COVID-19. MRG-001 exhibits immunoregulatory and regenerative properties in preclinical studies with a wide variety of diseases. Repairing damaged tissues in the lung and other organs, restoring the anti-virus immune system and modulating the inflammation are obvious therapeutic targets for COVID-19.~Part A has been completed in May 01, 2021.~Part B has been initiated in January 2022.
This study consists of two parts.~Part A (Phase I):~A Phase I Double-blind Randomized Placebo-controlled Study in Healthy Subjects to Assess the Safety, Pharmacokinetics, Pharmacodynamics of MRG-001~Part B (Phase 2):~A Phase IIa, Adaptive, Double-Blind, Randomized, Placebo-controlled, Multi-center Study in Hospitalized Patients Infected with Severe and Critical SARS-CoV-2 to Assess the Safety, Pharmacokinetics, Pharmacodynamics and Efficacy of MRG-001
