About this trial

This research study is studying DB-3Q as a possible treatment for medically refractory Crohn's disease. The purpose of this study is to research and evaluate safety and effectiveness of the administration of bone marrow mesenchymal stem cell (bmMSC) derived extracellular vesicles product, DB-3Q, the study drug for Crohn's disease.
