Rituximab and Cladribine in Treating Patients With Newly Diagnosed Non-Hodgkin's Lymphoma

• Status: Completed
• Trial end date: 2009-11-01
• Target enrollment: 0
• Participant gender: All

Summary

RATIONALE: Monoclonal antibodies such as rituximab can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Drugs used in chemotherapy such as cladribine work in different ways to stop cancer cells from dividing so they stop growing or die. Combining rituximab with cladribine may kill more cancer cells.

PURPOSE: This phase II trial is studying how well giving rituximab together with cladribine works in treating patients with newly-diagnosed mantle cell lymphoma.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Alliance for Clinical Trials in Oncology
• Collaborator: National Cancer Institute (NCI)
• Treatments: Cladribine; Rituximab

Criteria

DISEASE CHARACTERISTICS:

• Histologically confirmed mantle cell lymphoma*

• Measurable or assessable disease defined as at least one of the following:

• Lymph node or tumor mass that is 2.0 cm or more in at least one dimension by CT scan, MRI, or plain radiograph imaging OR greater than 1.5 cm in at least one dimension by physical exam

• Splenic enlargement, if the spleen is palpable, at least 3 cm below the left costal margin

• Diffuse infiltration of an organ such as the stomach, bone marrow, peripheral blood, liver, lungs, or bowel by lymphoma without a discrete mass would constitute assessable, but not measurable, disease

• No known CNS involvement NOTE: *If tumor tissue is unavailable for biopsy, blood or bone marrow specimens may be used to establish patient eligibility provided fusion signals indicate the presence of t(11;14)(q13;q32) by fluorescence in situ hybridization using CCND1/IGH AND mantle cell lymphoma involvement is determined by morphology
