Official Title

A Multicenter, Open-label Study to Evaluate the Safety of PROCHYMAL® (Remestemcel-L) Intravenous Infusion in Subjects Who Have Received Previous Remestemcel-L Induction Treatment for Treatment-refractory Moderate-to-severe Crohn's Disease


Subjects will receive infusions of PROCHYMAL on Day 42, Day 84, and Day 126 after initial infusion of PROCHYMAL in Protocol 603. Each infusion will contain 200 million cells. As subjects will be required to be in Protocol 603 during the entire duration of their participation in Protocol 611, all concomitant medication and safety information will be monitored by Protocol 603 and the combination of data from the two protocols
