Brief Summary:
This is a single-center Phase I study to determine the maximum tolerated dose and safety of Neihulizumab for the treatment of Minnesota standard-risk aGVHD. Patients undergoing allogeneic transplant with either a myeloablative or non-myeloablative conditioning regimen, and recipients of all donor sources will be enrolled to this trial.

Condition or disease Intervention/treatment Phase
Graft-versus-host Disease Biological: Neihulizumab, 3 mg/kg Drug: Neihulizumab, 6 mg/kg Drug: Neihulizumab, 9 mg/kg Drug: Neihulizumab Phase 1

Detailed Description:

Eligible patients will receive Neihulizumab weekly, for up to four doses. Responding patients, and patients with stable disease should receive all four weekly doses. Patients with skin only disease that clinically progresses by one stage (e.g, from stage 2 to stage 3), but remains less than stage 4, will receive a minimum two doses of Neihulizumab. At 72 hours after the second dose, non-responding patients will be withdrawn from the study. Responding patients should remain on study and receive four total doses. Patients with lower GI GVHD that progresses by at least one stage at 4 or more days after first dose will be withdrawn from the study. All patients receiving at least 1 dose of Neihulizumab will be evaluated for dose-limiting toxicities (DLTs) and adverse events.

Dose-escalation will be conducted according to a 3+3 design. The initial dose of Neihulizumab will be 6 mg/kg weekly (Dose level 1), and the highest dose administered will be 9 mg/kg weekly (Dose level 2). The DLT observation period will be 28 days. Patients will be entered sequentially to each dose level. For each dose level, if none of the first 3 patients at that level experiences a DLT, new patients may be entered at the next higher dose level. If 1 of 3 patients experiences a DLT, up to 3 more patients are to be treated at that same dose level. If none of the additional 3 patients at that dose level experiences a DLT, new patients may be entered at the next higher dose level. However, if 1 or more of the additional 3 patients experience a DLT, then no further patients are to be started at that dose level and the preceding dose is the maximum-tolerated dose (MTD). If 2 of 3 of the initially dosed patients experience a DLT on the first dose level, Neihulizumab will be administered at a lower dose, 3mg/kg weekly (Dose level -1). Finally, if 0 of 3 patients experience DLT at the highest dose level, an additional 3 patients will be enrolled to ensure that 6 patients are treated at the MTD. The MTD will be defined as the highest dose level at which no more than 1 of 6 treated patients, experiences a DLT.

Upon determination of MTD, an expansion cohort of 4-7 patients will be enrolled so that a total of 10 patients are enrolled at the potential Phase II dose. This will be done to preliminarily assess efficacy.

Primary Outcome Measures :
  1. Maximum-tolerated dose. [ Time Frame: Up to 28 days ]
    The maximum-tolerated dose will be defined as the highest dose level at which no more than one of six treated patients, experiences a dose-limiting toxicity.


Secondary Outcome Measures :
  1. Treatment response: Complete response [ Time Frame: Day 28 ]
    This outcome measures the number of patients with complete response. A complete response is GVHD that fully resolves at all sites. This will be determined by assessment of aGVHD response. Acute GVHD will be assessed by Mount Sinai Acute GVHD International Consortium (MAGIC) algorithm.

  2. Treatment response: Partial response [ Time Frame: Day 28 ]
    This outcome measures the number of patients with partial response. A partial response is GVHD that improves by at least one stage at one site, without worsening at any other site. This will be determined by assessment of aGVHD response. Acute GVHD will be assessed by Acute GVHD will be assessed by Mount Sinai Acute GVHD International Consortium (MAGIC) algorithm.

  3. Use of High Dose Steroids [ Time Frame: Day 28 ]
    The number of subjects requiring high-dose steroids (1mg/kg or greater daily) by Day 28.

  4. Non-relapse mortality. [ Time Frame: 6 months ]
    The number of subjects who expire without relapse.
