E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the efficacy of itolizumab versus placebo as initial therapy for aGVHD in combination with corticosteroids in achieving early disease response.
|
|
E.2.2 | Secondary objectives of the trial |
• To evaluate the durability of response to itolizumab versus placebo as initial therapy for aGVHD in combination with corticosteroids. • To evaluate systemic corticosteroid use in subjects treated with itolizumab versus placebo. • To assess the impact of itolizumab versus placebo on other clinically relevant efficacy measures, including survival outcomes and cGVHD incidence. • To evaluate the safety and tolerability of itolizumab versus placebo as initial therapy for aGVHD in combination with corticosteroids |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Age ≥12 years and >40 kg at informed consent/assent. Subjects <18 years may only enroll if locally permitted. - Has had an initial allogeneic HSCT for any indication using any graft source, donor source, conditioning regimen intensity or prophylaxis. NOTE: 2 allogeneic HSCTs may be allowed if GVHD did not occur after the first HSCT. - Has evidence of myeloid engraftment, defined as an absolute neutrophil count ≥500/mm3 (or ≥0.5 × 10exp9/L) achieved and sustained for 3 laboratory values obtained on different days. Laboratory values prior to Screening may be used. - Has a clinical diagnosis of aGVHD Grades III-IV or Grade II with LGI involvement based on Mount Sinai Acute GVHD International Consortium (MAGIC) grading criteria - at Screening and randomization. Biopsies to confirm aGVHD should be obtained but are not required and should not delay entry into the study. - Began initial systemic corticosteroid treatment with ≥ 1mg/kg/day methylprednisolone or equivalent for aGVHD ≤72 hours prior to the start of study drug dosing AND must receive 2 mg/kg/day methylprednisolone or equivalent on Day 1.

|
E.4 | Principal exclusion criteria |
- Has evidence of morphological relapsed, progressive, persistent, or untreated malignancy, with the exception of nonmelanoma skin cancer and in situ ductal carcinoma of the breast. - Has an unplanned donor lymphocyte infusion for persistent or recurrent malignancy after HSCT. - Has evidence of persistent molecular disease requiring treatment (eg, standard chemotherapy or tyrosine kinase inhibitors) that was not specified prior to HSCT. -Has evidence of cGVHD or overlap syndrome, as defined by 2014 NIH Consensus Criteria. - Is using immunosuppressants other than corticosteroids for the treatment of aGVHD. Continued use of immunosuppressants as GVHD prophylaxis agents is permitted. - Has received any systemic corticosteroids of >0.5 mg/kg/day methylprednisolone or equivalent for any indication other than aGVHD within 7 days before the onset of aGVHD. Systemic corticosteroids administered as premedication before blood product transfusions or IV medications to prevent infusion-related reactions are allowed. - Has a clinically active, uncontrolled bacterial, viral, or fungal infection, despite adequate treatment. No signs of progression of the infection can be present at randomization. Asymptomatic cytomegalovirus (CMV), Epstein–Barr virus (EBV), or human Herpesvirus 6 (HHV-6) viremia based on viral load or a viral load that is declining with treatment does not constitute a clinically active infection.
Other protocol-defined exclusion criteria apply. |
