A Randomized Phase III Trial of Consolidation with Autologous Hematopoietic Cell Transplantation Followed by Maintenance Rituximab vs. Maintenance Rituximab Alone for Patients with Mantle Cell Lymphoma in Minimal Residual Disease-Negative First Complete Remission
This randomized phase III trial studies rituximab after stem cell transplant and to see how well it works compared with rituximab alone in treating patients with in minimal residual disease-negative mantle cell lymphoma in first complete remission. Monoclonal antibodies, such as rituximab, may interfere with the ability of cancer cells to grow and spread. Giving chemotherapy before a stem cell transplant helps kill any cancer cells that are in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow. After treatment, stem cells are collected from the patient's blood and stored. More chemotherapy is then given to prepare the bone marrow for the stem cell transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy. Giving rituximab with or without stem cell transplant may work better in treating patients with mantle cell lymphoma.
The objective of this study is too compare overall survival in MCL patients in MRD-negative first complete remission (CR) who undergo auto-HCT followed by maintenance rituximab vs. maintenance rituximab alone (without auto-HCT).
Experimental: Auto-HCT + Rituximab
Patients receive standard of care preparative chemotherapy and undergo auto-HCT. Beginning 60-120 days after transplant, patients receive rituximab IV once every 8 weeks for up to 12 courses in the absence of disease progression or unacceptable toxicity.
Patients receive standard of care induction chemotherapy. Beginning 40-120 days after completion of chemotherapy, patients receive rituximab as in Group I.
Baptist MD Anderson Cancer Center
- Patients must have histologically confirmed mantle cell lymphoma, with documented cluster of differentiation (CD19) or CD20 expression and cyclin D1 (BCL1) by immunohistochemical stains and/or t(11;14) by cytogenetics or fluorescence in situ hybridization (FISH); the diagnosis must be confirmed by formal hematopathology review at the enrolling center, including assessment of Ki-67 proliferation index (=< 30% versus > 30% versus ?indeterminate? Ki-67 index)
- Patients should be deemed to be potentially eligible and willing candidates for auto-HCT by the enrolling physician
- Patient may be receiving or have completed induction therapy within 60 days prior to preregistration to step 0; no more than 300 days may have passed between the first day of induction therapy and preregistration to step 0
- Patient does not have any documented history of central nervous system (CNS) involvement by mantle cell lymphoma; this includes no evidence of parenchymal brain, spinal cord, or cerebrospinal fluid involvement; radiculopathy symptoms from nerve root compression by lymphoma do not constitute CNS involvement
- Patient must have archived formalin-fixed paraffin-embedded (FFPE) tumor tissue specimen from the original diagnostic biopsy available for submission to Adaptive Biotechnologies for ClonoSEQ ID molecular marker identification of unique clonal immunoglobulin deoxyribonucleic acid (DNA) sequence
- Patients must have completed induction therapy within 120 days prior to preregistration to step 0, AND no more than 300 days may have elapsed from the first dose of induction chemotherapy (cycle 1 [C1] day 1 [D1]) given, until the last day of induction chemotherapy administered; for those assigned to Arms A, C, or D, the date of transplant (?day 0?) must not be greater than 365 days after the first dose of induction chemotherapy (C1D1) given
- Patients must have achieved a radiologic complete or partial remission as defined by the Lugano criteria
- Patients must meet institutional eligibility requirements for stem cell transplant, including cardiac, renal, liver, and pulmonary requirements
- Patients have an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2
- Patient must be disease-free >= 3 years of prior malignancies with the exception of adequately treated non-melanoma skin cancer, adequately treated in situ carcinoma, low grade prostate carcinoma (Gleason grade =< 6) managed with observation that has been stable for at least 6 months
- Women must not be pregnant or breast-feeding
- Women of childbearing potential and sexually active males must be strongly advised to use an accepted and effective method of contraception or to abstain from sexual intercourse for the duration of their participation in the study
- Other eligibility criteria may apply
