Study Endpoints

Primary Endpoints

Overall Survival Rate Through Day 180
From Baseline Day 1 in the Study MSB-GVHD001 up to Day 180 in Study MSB-GVHD002 (180 days)

The overall survival rate is defined as the percentage of participants alive at the given time point. OS is defined as the time to death from the start of drug therapy.

Overall Response Rate (ORR) at Day 28 Post Initiation of Therapy
Day 28

ORR was defined as the percentage of participants who had achieved overall response. Overall response was defined as complete response (CR) plus partial response (PR) as per aGVHD response criteria. CR was defined as resolution of aGVHD in all involved organs. PR was defined as organ improvement of at least 1 stage without worsening of any other organ.

Protocol 260 - Response by Day 28, also called Overall Response (OR). OR includes complete response (CR) and partial response (PR)
28 Days
Protocol 261-The incidence rate of different adverse events among participants treated with either dose of Prochymal® in the preceding study (Protocol No. 260).

ArmTypeDescription
Safety populationEXPERIMENTALAll participants who were enrolled and had received at least 1 dose of remestemcel-L in Study MSB-GVHD001.
Remestemcel-L 2×10^6 MSCs/kgEXPERIMENTALParticipants were treated with intravenous (IV) remestemcel-L at a dose of 2×10\^6 mesenchymal stromal cells (MSCs)/kilogram (kg) actual body weight at Screening, twice per week, for each of 4 consecutive weeks (initial therapy) given at least 3 days apart and no more than 5 days apart for any infusion. Eligible participants received an additional once per week infusion, for each of 4 consecutive weeks (continued therapy) of remestemcel-L and twice per week infusions, for each of 4 consecutive weeks (aGVHD flare therapy) of remestemcel-L at the same initial therapy dose of 2×10\^6 MSCs/kg actual body weight at Screening.
Prochymal® - 2 Million cells/kgACTIVE_COMPARATORParticipants will receive Prochymal® consisting of 2 million hMSCs/kg actual body weight, intravenously (IV) on Days 1 and 4 along with daily standard of care which includes methylprednisolone 2 milligrams (mg)/kg IV or prednisone 2.5 mg/kg orally. Participants will also continue cyclosporine, tacrolimus, and/or mycophenolate mofetil (MMF) at full therapeutic doses.
Prochymal® - 8 Million cells/kgACTIVE_COMPARATORParticipants will receive Prochymal® consisting of 8 million hMSCs/kg actual body weight IV on Days 1 and 4 along with daily standard of care which includes methylprednisolone 2 mg/kg IV or prednisone 2.5 mg/kg orally. Participants will also continue cyclosporine, tacrolimus, and/or mycophenolate mofetil (MMF) at full therapeutic doses.
