Description of intervention(s) / exposure
Treatment: Drugs - Prochymal®
Other interventions - Placebo
Other interventions - Corticosteroid

Placebo comparator: Placebo - Participants will receive 6 infusions of placebo-matching Prochymal® intravenously (IV) during the first 4 weeks of the study. The first infusion will be administered within 72 hours of the start of systemic corticosteroid therapy. Participants will receive 4 infusions during the first 2 weeks (twice weekly at least 3 days apart), followed by 2 infusions administered once weekly over the subsequent 2 weeks up to Day 28.

Active comparator: Prochymal® 2x10^6 hMSC/kg - Participants will receive 6 infusions of Prochymal® 2x10\^6 human mesenchymal stem cells (hMSC)/kg IV during the first 4 weeks of the study. The first infusion will be administered within 72 hours of the start of systemic corticosteroid therapy. Participants will receive 4 infusions during the first 2 weeks (twice weekly at least 3 days apart), followed by 2 infusions administered once weekly over the subsequent 2 weeks up to Day 28.


Treatment: Drugs: Prochymal®
Prochymal® intravenous infusion.

Other interventions: Placebo
