Safety and Tolerability of Human Placenta-Derived Cells (PDA001) in Treatment-Resistant Crohn’s Disease

Abstract

PDA001 infusions appear safe and well-tolerated in subjects with treatment-resistant Crohn's disease. A response was seen in all subjects in the low-dose group. The high-dose group, with a higher baseline disease activity, had only 2 responders, suggesting a more treatment-resistant population. A phase 2 study in this patient population is ongoing.
