Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 54
Healthy volunteers: no

Brief summary:
To determine whether treatment with ustekinumab will alter the ratio of T Regulatory Cell (Treg)/total cluster of differentiation 4 (CD4)+ cells in peripheral blood at day 30 post-hematopoietic cell transplantation (HCT).

Detailed description:
This is a comparative study to assess the biologic and clinical activity of the agent ustekinumab when given in concert with our established regimen of SIR/TAC. Patients will be randomly assigned between the standard regimen of tacrolimus/sirolimus (TAC/SIR + placebo) vs. the investigational regimen of tacrolimus/sirolimus/ustekinumab (TAC/SIR/U) in a 1:1 scheme.

Arms:
arm 1: Ustekinumab, Tacrolimus and Sirolimus. Ustekinumab: 45 mg for adults who weight 100 kg or less; 90 mg for adults who weight greater than 100 kg. Tacrolimus: Level determined according to Blood and Marrow Transplant (BMT) Program standard operating procedures. Sirolimus: The dose for both loading and ongoing administration to be dictated by the standard operating procedures of the BMT program. arm 2: Placebo, Tacrolimus, and Sirolimus. Placebo: Identical volume to that of ustekinumab. Tacrolimus: Level determined according to Blood and Marrow Transplant (BMT) Program standard operating procedures. Sirolimus: The dose for both loading and ongoing administration to be dictated by the standard operating procedures of the BMT program.

Interventions: intervention 1: Ustekinumab intervention 2: Placebo intervention 3: Tacrolimus (TAC) intervention 4: Sirolimus
Intervention descriptions: intervention 1: One subcutaneous injection administered on day -1 and repeated on day +20 after transplant intervention 2: Subcutaneous injection of sterile saline (identical volume to that of ustekinumab) administered via the identical route and schedule as ustekinumab. intervention 3: Administered starting day -3 according to Blood and Marrow Transplant (BMT) Program standard operating procedures. TAC levels to be monitored and maintained at a target range of 3-7 given concurrent administration with sirolimus. Specific dose adjustments within this therapeutic range to be determined by the treating physician. intervention 4: Administered initially as an oral loading dose on day -1. Thereafter, SIR to be administered as an oral regimen daily. The dose for both loading and ongoing administration to be dictated by the standard operating procedures of the BMT program. SIR levels to be monitored according to standard procedures. Dose adjustments to be made according to drug levels, with target range of 5-14ng/mL (therapeutic range by Abbott Architect instrument at Moffitt).
