High-Dose Y-90-Ibritumomab Tiuxetan Added to Reduced-Intensity Allogeneic Stem Cell Transplant Regimen for Relapsed or Refractory Aggressive B-Cell Lymphoma

Research Study Description

This phase II trial studies the side effects and how well high-dose yttrium-90 (Y-90)-ibritumomab tiuxetan (anti-cluster of differentiation [CD]20) followed by fludarabine phosphate, low-dose total body irradiation (TBI), and donor peripheral blood stem cell transplant (PBSCT) work in treating patients with aggressive B-cell lymphoma that has returned after a period of improvement (relapsed) or has not responded to previous treatment (refractory). Radiolabeled monoclonal antibodies, such as Y-90-ibritumomab tiuxetan, can find cancer cells and carry cancer-killing substances to them with less effect on normal cells. Giving chemotherapy, such as fludarabine phosphate, and TBI before a donor PBSCT helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. However, high-dose radiolabeled antibodies also destroy healthy blood cells in the patient's body. When healthy stem cells from a donor are infused into the patient (stem cell transplant), they may help the patient's body replace these blood cells. Giving high-dose Y-90-ibritumomab tiuxetan followed by fludarabine phosphate, TBI, and donor PBSCT may be an effective treatment for patients with B-cell lymphoma.

Eligibility Criteria (must meet the following to participate in this study)

Ages Eligible for Study: 18 Years and older

Genders Eligible for Study: Both

- Patients must have a histologically confirmed diagnosis of aggressive B-cell lymphoma (diffuse large B-cell lymphoma [DLBCL], Burkitt lymphoma [BL], etc.) expressing the CD20 antigen and have failed at least one prior standard systemic therapy

- Patients must have relapsed after high-dose therapy and autologous transplantation or be ineligible for high-dose therapy and autologous transplantation; patients that have failed autologous transplantation are those with persistent disease > 30 days after transplant; those ineligible for autologous transplant include those with chemoresistant disease (i.e., patients who have not achieved a partial response or better with their most recent chemotherapy regimen), are expected to have a poor outcome from autologous transplant (e.g., DLBCL relapsing within one year of rituximab, cyclophosphamide, doxorubicin hydrochloride, vincristine sulfate, prednisone [R-CHOP]-like chemotherapy, double hit lymphoma, v-myc myelocytomatosis viral oncogene homolog (avian) positive [MYC+] lymphoma, persistent positron emission tomography [PET] positivity after chemotherapy), are unable to collect sufficient or tumor-free autologous stem cells per Seattle Cancer Care Alliance (SCCA) standard practice, are unable to tolerate the high-dose autologous conditioning regimens, or who refuse a high-dose autologous transplant regimen

- Creatinine (Cr) < 2.0

- Bilirubin < 1.5 mg/dL with the exception of patients thought to have Gilbert's syndrome, who may have a total bilirubin above 1.5 mg/dL

- Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) < 3 x upper limit of normal (ULN)

- Patients must have an expected survival without treatment of > 60 days and must be free of major infection including human immunodeficiency virus (HIV)

- Patients must have an HLA-identical related or HLA-matched unrelated donor

Other eligibility criteria may apply.

Exclusions (conditions that would prevent participation in this study)

- Systemic anti-lymphoma therapy given within 30 days prior to therapeutic 90Y-ibritumomab tiuxetan dose

- Inability to understand or give an informed consent

- Active central nervous system lymphoma

- Pregnancy

- Fertile men or women unwilling to use contraceptive techniques during and for 12 months following treatment

- Southwest Oncology Group (SWOG)/Eastern Cooperative Oncology Group (ECOG) performance score >= 2

- High-dose chemotherapy or external beam radiation therapy to lung, liver, or kidneys > 20 Gy within the previous 100 days prior to therapeutic 90Y-ibritumomab tiuxetan dose

- Medical condition that would contraindicate allogeneic transplantation as per standard practice guidelines (e.g., impaired cardiopulmonary function, hepatitis, etc)

- Altered biodistribution (determined following trace-labeled 111In-ibritumomab tiuxetan dose)

Other exclusion criteria may apply.
