Primary Outcome Measures
NameTimeMethod
Percent of participants with complete or partial response to acute Graft-versus-Host Disease (GVHD) treatment28 days post-randomization

Acute GVHD will be graded and assessed for response based on Harris criteria (stage 0, 1, 2, 3, 4) for skin, liver, upper gastrointestinal (GI) tract, and lower GI tract. Complete response (CR) is defined as a score of 0 for the GVHD staging in all evaluable organs.

Partial response (PR) is defined as improvement in one or more organs involved with GVHD symptoms without progression in others.

Secondary Outcome Measures
NameTimeMethod
Percent of participants with overall survival and progression-free survivalup to 12 months post-randomization

An event for overall survival is death from any cause, while an event for progression-free survival is death from any cause or relapse/progression of the primary disease.

Percent of participants with GVHD-free survivalDay 56 post-randomization

Patients alive, free of active acute or chronic GVHD, and without other systemic agents or escalation of steroids added for treatment of GVHD will be considered successes for this endpoint.

Duration of response (DOR)up to 12 months post-randomization

DOR is defined as time from the Day 28 response (CR or PR) to any of the following events: relapse/progression of acute GVHD, new systemic salvage therapy for acute GVHD, re-escalation of steroids to greater or equal to 2.5 mg/kg prednisone or equivalent, or death from any cause.

Percent of participants with non-relapse mortality (NRM)up to 12 months post-randomization

An event of NRM is death without prior evidence of relapse/progression of the primary disease, where relapse/progression is treated as a competing risk.

Percent of participants with Grade 2 to 3 systemic infectionsup to 30 days after the last dose of study drug

The incidence of Grade 2 to 3 systemic infections. Grade 2 to 3 systemic infections will be defined according to BMT CTN Manual of Procedures.

Percent of participants with chronic GVHDup to 12 months post-randomization

Chronic GVHD is defined per National Institutes of Health (NIH) Consensus Criteria. Diagnosis of chronic GVHD of any severity (mild, moderate, or severe) is considered an event for this endpoint.

Percent of participants with responseAt Day 7, 14, 21, 28, 56, and 86 post-randomization

The proportion of patients with CR, PR (including subset with VGPR), and treatment failure (TF). The designation of TF will consist of patients with no response (NR), mixed response (MR), progression or initiation of additional systemic (second-line) GVHD therapies or escalation of steroids. Death from any cause will also be considered a TF.

Percent of participants with Grade 3 to 5 treatment-emergent adverse events (TEAEs)up to 30 days after the last dose of study drug

The incidence of Grade 3 to 5 TEAEs (per Common Terminology Criteria for Adverse Events \[CTCAE\] Version 5.0)

Percent of participants with disease relapseup to 12 months post-randomization

The cumulative incidence of relapse/progression of the primary disease, with death prior to relapse/progression treated as a competing risk.
