About
This phase II trial studies how well ofatumumab in combination with cyclophosphamide, doxorubicin hydrochloride, vincristine sulfate, and dexamethasone alternating with ofatumumab in combination with cytarabine and methotrexate works in treating patients with newly diagnosed mantle cell lymphoma (MCL). Monoclonal antibodies, such as ofatumumab, may interfere with the ability of cancer cells to grow and spread. Drugs used in chemotherapy, such as cyclophosphamide, doxorubicin hydrochloride, vincristine sulfate, dexamethasone, cytarabine, and methotrexate, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ofatumumab together with alternating regimens of combination chemotherapy may kill more cancer cells.
Full description
PRIMARY OBJECTIVES:
I. To determine the overall response rate (ORR), and in particular, the complete remission rate (CRR) in previously untreated MCL treated with ofatumumab in combination with aggressive chemo-immunotherapy.
SECONDARY OBJECTIVES:
I. To determine the high sensitivity flow cytometry (HSFCM) complete remission rate (HSFCM-CRR) in previously untreated MCL treated with ofatumumab in combination with aggressive chemo-immunotherapy +/- high dose chemotherapy and autologous stem cell transplant (HDC-ASCT).
II. To determine the time-to-progression (TTP), progression-free survival (PFS) and overall survival (OS) of patients with previously untreated MCL treated with ofatumumab and aggressive chemoimmunotherapy +/- HDC-ASCT.
III. To determine the toxicity profiles of ofatumumab in combination with high dose cytarabine chemoimmunotherapy +/- HDC-ASCT.
IV. To correlate minimal residual disease (MRD) at different time intervals with TTP, PFS, and OS.
V. To correlate surface cluster of differentiation (CD)20 levels, Ki67, and additional cytogenetic abnormalities in pretreatment tumor biopsies with respect to ORR, CRR, TTP, PFS, or OS.
VI. To determine the relationship between proliferation signature and clinical outcome using quantitative real-time reverse-transcriptase polymerase chain reaction (RT-PCR).
VII. To determine changes in surface CD20 levels, Ki67, or gain of additional cytogenetic abnormalities in relapsed/refractory tumor specimens.
VIII. To correlate serum component (C)3, C4, and hemolytic complement (CH)50 levels measured at baseline and at the end of first ofatumumab infusion with ORR, CRR, median response rate (MRR), TTP, PFS and OS.
IX. Evaluate the ability of the induction and consolidation therapy to get 70% of patients to autologous stem cell transplantation.
X. Evaluate the tolerability and CD34+ cell yield following therapy with patient and hyper-fractionated cyclophosphamide, doxorubicin hydrochloride, vincristine sulfate, and dexamethasone (HyperCVAD)/high-dose cytarabine and methotrexate (HD-MA).
XI. To compare differences in response rate in patients with MCL treated with ofatumumab + HyperCVAD/HD-MA according Cheson and Modified Cheson Criteria.
OUTLINE:
COURSES 1, 3, and 5 (O-HyperCVAD): Patients receive ofatumumab intravenously (IV) on day 1, cyclophosphamide IV over 2 hours every 12 hours for 6 doses on days 3-5, doxorubicin hydrochloride IV continuously over 72 hours on days 6-8, vincristine sulfate IV on days 6 and 13, and dexamethasone IV or orally (PO) on days 3-6 and 13-16.
COURSES 2, 4, and 6 (O-HD-MA): Patients receive ofatumumab IV on day 1, methotrexate IV continuously over 24 hours on day 3, and cytarabine IV over 2 hours every 12 hours on days 4-5.
Treatment repeats every 21 days for 6* courses in the absence of disease progression or unacceptable toxicity.
Eligible patients then undergo standard high dose chemotherapy and autologous stem cell transplant (HDC-ASCT). Patients achieving a high sensitivity flow cytometry complete remission (HSFCM-CR) after 2 courses may proceed to HDC-ASCT after completing 4 courses of treatment.
After completion of study treatment, patients are followed up every 4 months for 2 years, every 6 months for 3 years, and then as clinically instructed.

Inclusion criteria
Histologically documented mantle cell lymphoma with co-expression of CD20 and CD5 and lack of CD23 expression by immunophenotyping and at least one of the following confirmatory tests: 1) positive immunostaining for cyclin D1; 2) the presence of t(11;14) on cytogenetic analysis; OR 3) molecular evidence of B-cell leukemia/lymphoma 1 (bcl-1)/immunoglobulin heavy locus (IgH) rearrangement
Extent of disease: stage I - IV; patients with nodular histology mantle cell lymphoma must have Ann Arbor stage III or IV disease to be eligible
Measurable or assessable disease is required; measurable tumor size (at least one node measuring 2.25 cm^2 in bidimensional measurement)
No active central nervous system (CNS) disease defined as symptomatic meningeal lymphoma or known CNS parenchymal lymphoma; a lumbar puncture demonstrating mantle cell lymphoma at the time of registration to this study is not an exclusion for study enrollment
Patients must be previously untreated
No prior radiation therapy for mantle cell lymphoma
>= 2 weeks since major surgery
No known hypersensitivity to murine products
No medical condition requiring chronic use of high dose systemic corticosteroids (i.e., doses of prednisone higher than 10 mg/day or equivalent)
No human immunodeficiency virus (HIV) infection; patients with a history of intravenous drug abuse or any behavior associated with an increased risk of HIV infection should be tested for exposure to the HIV virus; patients who test positive or who are known to be infected are not eligible; an HIV test is not required for entry on this protocol, but is required if the patient is perceived to be at risk
Non-pregnant and non-nursing; women and men of reproductive potential should agree to use an effective means of birth control
Patients who test positive for hepatitis C antibody (Ab) are eligible provided all of the following criteria are met: 1) total bilirubin =< 2 x upper limit of normal; 2) AND aspartate aminotransferase (AST) =< 3 x upper limit of normal; AND 3) liver biopsy (pathology) demonstrates =< grade 2 fibrosis and no cirrhosis
Specific guidelines will be followed regarding inclusion of MCL based on hepatitis B serological testing as follows:
Hepatitis B surface antigen (HBsAg) negative, hepatitis B core antibody (HBcAb) negative, hepatitis B surface antibody (HBsAb) positive MCL patients are eligible
Patients who test positive for HBsAg are ineligible (regardless of other hepatitis B serologies)
For MCL patients with HBsAg negative, but HBcAb positive (regardless of HBsAb status), should have hepatitis B virus (HBV) deoxyribonucleic acid (DNA) testing done and protocol eligibility determined as follows:
Patients must not have a history of cardiac disease, defined as New York Heart Association class II or greater or clinical evidence of congestive heart failure (CHF)
No known hypersensitivity to ofatumumab, humanized antibodies or chemotherapy agents throughout the protocol
Left ventricular ejection fraction (LVEF) by multi gated acquisition scan (MUGA) or echocardiogram (ECHO) >= 45%
Neutrophils > 1000/uL
