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.
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.
Inclusion Criteria:
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
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)
Patient must have archived formalin-fixed paraffin-embedded (FFPE) tumor tissue specimen from the original diagnostic 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
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
INCLUSION CRITERIA FOR TREATMENT ASSIGNMENT (STEP 1): Institution has received results from Adaptive Biotechnologies as defined by one of the following criteria:
INCLUSION CRITERIA FOR TREATMENT ASSIGNMENT (STEP 1): Patients must have completed induction therapy within 150 days prior to registration to step 1, 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
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
INCLUSION CRITERIA FOR TREATMENT ASSIGNMENT (STEP 1): (HIV) positive patients are not excluded, but to enroll, must meet all of the below criteria:
INCLUSION CRITERIA FOR TREATMENT ASSIGNMENT (STEP 1): Patient must not be pregnant or breast-feeding due to the potential for congenital abnormalities and of harm to nursing infants due to the treatment regimens used
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).
Your pathology report is the document that shows this.
Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
The number of CD4 cells, a type of white blood cell, in a given amount of blood. It is used to follow how well the immune system is doing in HIV.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
