Summary

This 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. Immunotherapy with rituximab, may induce changes in body’s immune system and may interfere with the ability of tumor 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.

Objectives

PRIMARY OBJECTIVE:
I. To compare overall survival in mantle cell lymphoma (MCL) patients in minimal residual disease (MRD)-negative first complete remission (CR) who undergo autologous hematopoietic stem cell transplantation (auto-HCT) followed by maintenance rituximab versus (vs.) maintenance rituximab alone (without auto-HCT).

SECONDARY OBJECTIVES:
I. To compare progression-free survival in MCL patients in MRD-negative CR who undergo auto-HCT followed by maintenance rituximab vs. maintenance rituximab alone.
II. To define the overall survival and progression-free survival at 2 and 5 years of chemosensitive but MRD-positive CR patients who undergo auto-HCT followed by 3 years of maintenance rituximab.
III. To define the overall survival and progression-free survival at 2 and 5 years of chemosensitive but MRD-positive partial response (PR) patients who undergo auto-HCT followed by 3 years of maintenance rituximab.
IV. To define the overall survival and progression-free survival at 2 and 5 years of MRD-negative PR patients who undergo auto-HCT followed by 3 years of maintenance rituximab.
V. To define the overall survival and progression-free survival at 2 and 5 years of MRD-indeterminate patients who undergo auto-HCT followed by 3 years of maintenance rituximab.
VI. To describe the rate of complications (serious infection, hospitalization, need for intravenous immune globulin) in MCL patients undergoing maintenance rituximab following auto-HCT.
VII. To determine the prognostic impact of MRD status at day 100, in MCL patients who were MRD-positive (including MRD-positive CR and MRD-positive PR) prior to auto-HCT.

EXPLORATORY TOBACCO USE OBJECTIVES:
I. To determine the effects of tobacco, operationalized as combustible tobacco (1a), other forms of tobacco (1b), and environmental tobacco exposure (ETS) (1c) on provider-reported cancer-treatment toxicity (adverse events (both clinical and hematologic) and dose modifications).
II. To determine the effects of tobacco on patient-reported physical symptoms and psychological symptoms.
III. To examine quitting behaviors and behavioral counseling/support and cessation medication utilization.
IV. To explore the effect of tobacco use and exposure on treatment duration, relative dose intensity, and therapeutic benefit.

OUTLINE: Patients are randomized to 1 of 2 groups.

GROUP I: Patients receive standard of care preparative chemotherapy and undergo auto-HCT. Beginning 100-140 days after transplant, patients receive rituximab intravenously (IV) or rituximab and hyaluronidase human subcutaneously (SC) or any approved rituximab biosimilar at the approved dose once every 8 weeks for up to 18 cycles in the absence of disease progression or unacceptable toxicity.

GROUP II: Patients receive standard of care induction chemotherapy. Beginning 40-180 days after completion of chemotherapy, patients receive rituximab or rituximab and hyaluronidase human or any approved rituximab biosimilar at the approved dose, as in Group I.

Patients undergo positron emission tomography (PET), computed tomography (CT) or PET/CT throughout the study. Patients may undergo blood sample collection during screening and on study. Patients also may undergo bone marrow biopsy and aspirate during screening.

After completion of study treatment, patients are followed up every 3 and 6 months for 10 years.

Eligibility

1. INCLUSION CRITERIA FOR SCREENING (STEP 0 - PREREGISTRATION)
2. Age >= 18 and =< 70 years
3. Patients must have histologically confirmed mantle cell lymphoma, with cyclin D1 by immunohistochemical stains and/or t(11;14) by cytogenetics or fluorescence in situ hybridization (FISH). If patient has cyclin D1 negative mantle cell lymphoma with classical morphology and an expression profile (including SOX11+) that is otherwise indistinguishable from mantle cell lymphoma, communication with investigator is required for consideration of enrollment. The proliferation rate, using Ki-67 or MIB-1, should also be determined, but is not required until step 1 registration; patients may register to step 0 without a documented Ki-67 index
4. In the opinion of the enrolling physician, patients must be felt to be a candidate for autologous stem cell transplantation
5. Patient may be about to begin, be receiving or have completed induction therapy within 120 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 * For patients who have completed induction therapy and have been restaged, restaging evaluation must show status of partial (PR) or complete response (CR); post-induction patients with evidence of clinical disease progression are not eligible for preregistration * Up to two regimens of therapy (conventional chemotherapy, antibody therapy, or an oral regimen) are allowed as long as a continuous response was ongoing throughout therapy; overall, a partial response needs to have been achieved (using studies at the time of diagnosis as the baseline) ** NOTE: For example, a patient who started treatment with rituximab/bendamustine and was then switched to rituximab(R)-cyclophosphamide, doxorubicin hydrochloride, vincristine sulfate, and prednisone (CHOP) (due to insufficient response or excessive toxicity) would be counted as having received 2 regimens; however, R-CHOP alternating with R-dexamethasone, high-dose cytarabine, and cisplatin (DHAP) as a planned induction regimen would count as one regimen
6. 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
7. 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 * NOTE: If adequate tumor tissue is not available, peripheral blood collected prior to start of treatment with high disease burden (> 5%) is acceptable for molecular marker identification (ID) testing ** Adaptive Biotechnologies will forward results within fourteen (14) days of receipt of any stored (e.g. frozen or FFPE) tumor tissue specimen to the submitting institution and to the ECOG-American College of Radiology Imaging Network (ACRIN) Operations Office * NOTE: Patients for whom the molecular marker is identified will have peripheral blood collected after completion of induction (patient’s disease status is PR or CR) and submitted to Adaptive Biotechnologies for minimal residual disease (MRD) assessment ** Adaptive Biotechnologies will forward results within ten to fourteen (10-14) days of receipt of fresh peripheral blood specimen to the submitting institution and to the ECOG-ACRIN Operations Office
