EPOCH-R Chemotherapy Plus Bortezomib to Treat Mantle Cell Lymphoma

Study Summary

This study will evaluate the effectiveness of etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin-rituximab (EPOCH-R) chemotherapy plus bortezomib for treating mantle cell lymphoma, a cancer of white blood cells called lymphocytes. EPOCH-R consists of the drugs prednisone, etoposide, doxorubicin and vincristine, with the addition of a new drug called rituximab. In a recent study of patients with newly diagnosed mantle cell lymphoma, 92 percent had a complete remission of their disease after treatment with EPOCH-R. This study will test whether adding bortezomib as "maintenance therapy" once chemotherapy is finished will lengthen the time before the disease relapses and improve the overall cure rate. Patients 18 years of age and older with mantle cell lymphoma may be eligible for this study. Candidates are screened with a medical history and physical examination, blood and urine tests, electrocardiogram, multi-gated acquisition scan (MUGA) or echocardiogram, imaging studies and biopsy to determine the extent of disease, and possible colonoscopy. Participants undergo treatment in three parts, as follows: * Part 1: Bortezomib alone: Patients receive 4 doses of bortezomib over 3 weeks. The drug is injected into a vein over about 30 seconds. * Part 2: EPOCH-R chemotherapy plus bortezomib: This phase of treatment begins 3 to 4 weeks after completing Part 1. Treatment is given on an outpatient basis in six 3-week cycles, with all drugs administered over the first 5 days of each cycle. Patients take prednisone by mouth on days 1 to 5 and etoposide, doxorubicin, and vincristine as a 96-hour infusion through a vein over days 1 to 5. The infused drugs are delivered through a lightweight, portable infusion pump. Rituximab is given by vein over several hours on day 1 immediately before the chemotherapy infusion begins. Bortezomib is given by vein over 30 seconds on day 1 before the rituximab and again on day 4. Cyclophosphamide is given by vein over about 15 minu

Primary Outcome

Time interval from start of treatment to documented evidence of disease progression. Progression is defined by at least one of the following: ≥50% increase in the sum of the products of at least two lymph nodes, appearance of new lymph nodes, ≥50% increase in the size of the liver and/or spleen as determined by measurement below the respective costal margin, appearance of new palpable hepatomegaly or splenomegaly that was not previously present, and ≥50% increase in the absolute number of circul
