Study of Intravenous Administration of Allogeneic Adipose Stem Cells for COVID-19

This study is designed rapidly assess safety and preliminary efficacy in hospitalized patients with COVID-19 respiratory distress to provide clinical guidance for possible wider use in treating patients in this pandemic environment. This data will be used for FDA IND filings and pursuit of a BLA.

Purpose of Study

This study is single arm, non-randomized Phase 1 study of the safety and preliminary efficacy of PSC-04, an adipose-derived allogeneic mesenchymal stem cell. The outcome data will be compared to contemporaneous non-enrolled patients at the same clinical site(s) as the enrolled patients.

Study Objectives:

Primary: To evaluate the safety of intravenous infusion of allogeneic adipose stem cells in patients with COVID-19 disease and respiratory distress.

Secondary: To evaluate a set of secondary safety and efficacy outcome variables to give guidance in assessing the risk/benefit ratio in patients with COVID-19 respiratory distress.
