Dose-Intense Yttrium-90 Ibritumomab Tiuxetan (Zevalin)-Containing Non-Myeloablative Conditioning for Allogeneic Stem Cell Transplantation in B-cell Malignancies
In Brief
A Phase 2 clinical trial evaluating Rituximab, 111In Ibritumomab, and 10 other interventions for Leukemia and Lymphoma. Completed, enrolled 20 participants across 1 site.
Detailed Summary
The goal of this clinical research study is to learn if adding Zevalin (ibritumomab tiuxetan) to low-intensity chemotherapy (the combination of rituximab, bendamustine, and fludarabine), followed by an allogeneic stem cell transplant, can help to control lymphoma. The safety of this combination will also be studied. Two (2) forms of ibritumomab tiuxetan will be used in this study. 90Y-ibritumomab tiuxetan is designed to attach to lymphoma cells and destroy the cells using a radioactive particle that is attached to it. 111In-ibritumomab tiuxetan is like 90Y- ibritumomab tiuxetan, but the radioactive particle that is attached to it does not kill lymphoma cells. The radioactive particle makes the drug able to be seen inside your body. It is being used in this study to predict how fast the study drug will travel in the body and how long the drug stays in the body. Rituximab is designed to attach to lymphoma cells, which may cause them to die. Bendamustine is designed to damage and destroy the DNA (genetic material) of cancer cells. Fludarabine is designed to make cancer cells less able to repair damaged DNA. This may increase the likelihood of the cells dying.

Timeline
Interventions
250 mg/m2 by vein preceding 111In Ibritumomab and (90Y) ibritumomab tiuxetan administration, respectively on Days -22 and -14.
(5.0 mCi +/- 10% of 111In) by vein immediately following the infusion of rituximab on Day -22.
Day -22, -21 to -16: Planar scintigraphy whole-body imaging started on Day -22 post 111In Ibritumomab infusion prior to voiding, and repeated 3-6 hours later (including Single Photon Emission-Computed Tomography/Computed Tomography (SPECT/CT) scan of the abdomen). Whole-body planar scintigraphy imaging will be repeated between 22-26 hours, then between 70-74 hours, and later between 142-146 hours post 111In Ibritumomab injection.
Calculated to deliver not below 10 Gy to normal organs (liver, lungs, kidneys) by vein post rituximab on Day -14.
30 mg/m2 intravenously on Days -5, -4, and -3.
130 mg/m2 intravenously on D-5, -4 and -3.
1 mg/kg (based on actual body weight) on Days -2 and -1 will be administrated to patients receiving a cord blood (CB) and a matched unrelated donor (MUD).
Starting dose of 0.015 mg/kg (ideal body weight) as a 24 hour continuous infusion daily adjusted to achieve a therapeutic level of 5-15 ng/ml. Tacrolimus is changed to oral dosing when tolerated and can be tapered off after day +90 if no Graft versus Host Disease (GVHD) is present. For patients receiving cord blood (CB) graft, the Graft versus Host Disease (GvHD) prophylaxis will be with Tacrolimus. Tacrolimus will start on D-2 administrated at starting dose 0.03 mg/kg or 0.015 mg/kg (ideal body weight) by vein starting on D -2 and will be tapered around Day +180 if no GvHD is present.
5 mg/m2 by vein on Day +1, +3 and +6. Patients receiving an unrelated graft will also be given methotrexate on Day +11 after the transplant.
15 mg/kg (actual body weight with a maximum dose of 1 gram twice daily) by vein or by mouth administered from Days -3 to +45 and then tapered to end by day 100 if there is no Graft versus Host Disease (GVHD).
5 mcg/kg/day subcutaneously beginning Day +7 for patients receiving related and matched unrelated donor (MUD) grafts and on Day 0 for patients receiving a cord blood (CB). G-CSF will continue until the absolute neutrophil count (ANC) is \> 500 \* 10/L for 3 consecutive days.
