Brief Summary: Biological therapies such as MDX-010 work in different ways to stimulate the immune system and stop cancer cells from growing This phase III trial is studying the side effects and best dose of MDX-010 and to see how well it works in treating patients with recurrent or refractory B-cell non-Hodgkins lymphoma
Detailed Description: PRIMARY OBJECTIVES
I To characterize the safety profile of MDX-010 ipilimumab monoclonal antibody and identify a tolerable immunologically active dose level in B cell lymphoma patients
II To evaluate the clinical response rate in B cell lymphoma patients treated with MDX-010
SECONDARY OBJECTIVES
I To evaluate the phenotype and function of memory T cells before and after treatment with MDX-010 by
Quantitation and phenotypic characterization of peripheral blood and tumor infiltrating T-cells including cluster of differentiation CD4CD25 regulatory T cells Measurement of tumor-specific T cells in peripheral blood lymphocytes Measuring proliferation of memory T cells in response to recall antigens tetanus toxoid and keyhole limpet hemocyanin KLH
II Measurement of anti-tumor antibodies in serum pre- and post-therapy III To evaluate the time to progression IV To evaluate the duration of response to treatment with MDX-010
OUTLINE This is a multicenter open-label phase I dose-escalation study followed by a phase II study Patients are grouped according to prior treatment with a vaccine therapy for lymphoma yes vs no
PHASE I Patients receive anti-cytotoxic T-lymphocyte-associated antigen-4 monoclonal antibody MDX-010 IV over 90 minutes on day 1 Treatment repeats every 28 days for a total of 4 courses in the absence of disease progression or unacceptable toxicity
Cohorts of 6 patients from each group receive escalating doses of MDX-010 until the maximum tolerated dose MTD is determined The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity
PHASE II Patients receive MDX-010 as in phase I at the MTD
Patients are followed at 1 and 4 months and then every 6 months for up to 2 years
