Outcomes

Primary Outcomes

Percentage of Participants Achieving Overall Response (OR) At Day 28

OR was defined as graft-versus-host disease (GvHD) complete response (CR) + partial response (PR), defined as: - GvHD CR was complete resolution of all signs and symptoms of acute GvHD in all organs without intervening salvage and GvHD PR was improvement of 1 stage in 1 or more organs involved in GvHD without progression in other organs.

Time frame: Day 28

Secondary Outcomes

Percentage of Participants Achieving Gastrointestinal (GI) Response at Day 28

GI response was defined as complete response (CR) + partial response (PR), defined as: - GI CR was able to eat; not requiring parenteral nutrition, and passing primarily formed stools - GI PR was decrease in need for parenteral nutrition to less than or equal to (\<=) 50% of required calories; and reduction of stool volume by greater than or equal to (\>=) 50%, without ileus.

Time frame: Day 28

Percentage of Participants Achieving Overall Response at Day 56

Overall response was defined as graft-versus-host disease (GvHD) complete response (CR) + partial response (PR), defined as: - GvHD CR was complete resolution of all signs and symptoms of acute GvHD in all organs without intervening salvage - GvHD PR was improvement of 1 stage in 1 or more organs involved in GvHD without progression in other organs.

Time frame: Day 56

Acute Graft-versus-host Disease (GvHD) Grading at Days 28, 56 and 180

Grading of GvHD was performed by the investigator according to the modified International Bone Marrow Transplant Registry (IBMTR) grading system which classifies the degree of involvement of each organ system by stage on a scale of 0 to 4. The degree of skin involvement was staged depending upon degree and severity of the lesions: Stage 1: Maculopapular rash over less than (\<) 25% of body area, Stage 2: Maculopapular rash over 25 to 50% of body area, Stage 3: Generalized erythroderma, Stage 4: Generalized erythroderma with bullous formation. Degree of GI involvement was staged based on severity of diarrhoea: Stage 1: 500 to 1000 mL/day,Stage 2: 1000 to 1500 mL/day, Stage 3: 1500 to 2000 mL/day, Stage 4: greater than (\>) 2000 mL/day OR pain OR ileus. Degree of liver involvement was staged based upon serum total bilirubin level as follows: Stage 1: 2 to 3 mg/dL, Stage 2: 3 to 6 mg/dL, Stage 3: 6 to 15 mg/dL, Stage 4: \>15 mg/dL.
