SCCA Lymphoma Clinical Trials
This phase II trial studies the side effects and how well giving high-dose yttrium-90 (Y-90)-ibritumomab tiuxetan (anti-CD20) followed by fludarabine phosphate, low-dose total body irradiation (TBI), and donor peripheral blood stem cell transplant (PBSCT) works in treating patients with relapsed or refractory aggressive B-cell lymphoma. 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.
- 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 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
- Patients must have evidence of persistent lymphoma by physical examination, radiographic studies, blood or bone marrow evaluation, flow cytometry, or polymerase chain reaction (PCR)
- Creatinine (Cr) < 2.0
- Bilirubin < 1.5mg/dL with the exception of patients thought to have Gilbert's syndrome, who may have a total bilirubin above 1.5mg/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
- Systemic anti-lymphoma therapy given within 30 days prior to therapeutic 90Y-ibritumomab tiuxetan dose
- Inability to understand or give an informed consent
- Central nervous system lymphoma
- 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 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 In-ibritumomab tiuxetan dose)
