EPOCH-R Chemotherapy Plus Bortezomib to Treat Mantle Cell Lymphoma

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 minutes on day 5 immediately after the chemotherapy infusion is completed. Patients are taught how to self inject granulocyte colony stimulating factor (G-CSF), a drug that helps boost white cell counts after chemotherapy. They inject the drug under the skin (like an insulin shot) for 10 days of each cycle beginning day 6. Patients also take an antibiotic to help prevent infection during chemotherapy.
* Part 3: Bortezomib alone: After completing EPOCH-R-B therapy, patients are randomly assigned to receive or not to receive bortezomib alone. The drug is given in 2 doses over 5 days, with a break of 16 days before the next dose. These 3-week cycles continue for up to 18 months or until the disease comes back or worsens. Patients who are assigned to the group that does not receive bortezomib will be offered the drug if their disease relapses.

During therapy, patients have tests performed on their bone marrow, tumor tissue, blood or other fluids to look at different genes and proteins that may be involved in the development of their lymphoma or the reaction of the immune system. A tissue biopsy is done before treatment begins and a day after treatment starts. Disease progress is followed with computed tomography (CT) scans and blood tests. When treatment is completed, patients whose cancer has disappeared are scheduled for periodic follow-up examinations and tests. Those whose disease remains or recurs may be offered participation in another protocol if an appropriate one is available or are returned to the care of their local physician.
