B-Cell Neoplasm clinical trials

Lenalidomide Combined With Modified DA-EPOCH and Rituximab (EPOCH-R2) in Primary Effusion Lymphoma or KSHV-associated Large Cell Lymphoma

Background: Primary effusion lymphoma (PEL) is a rare disease with no standard treatment. Researchers want to see if a drug called lenalidomide along with common chemotherapy drugs may be effective in treating PEL. Objective: To test a new treatment for PEL. Eligibility: People ages 18 and older with PEL. Design: Participants will be screened with blood tests, imaging studies, a physical exam, and other tests. Participants will have tests to evaluate their disease. These may include: Blood tests Scans Lumbar puncture. Fluid around the spinal cord will be removed with a needle. Bone marrow removed with a needle and studied Samples of skin or lymph nodes removed Fluid removed from around organs Lung and eye tests Tubes with cameras taking pictures of airways or digestive tract Participants will take lenalidomide pills for 10 days. They will keep a pill diary. Participants will have a catheter (small tube) placed in the large vein in the arm or chest. Participants will get DA-EPOCH-R as intravenous infusions by catheter over several days. This will be repeated in 21-day cycles. Most participants will have 6 cycles. Participants will get the drug filgrastim by injection under the skin. They will get the drug methotrexate injected into the spinal fluid. During the study, participants will have the following tests done at least once: Medical history Physical exam Blood, urine, and stool tests Lesions photographed and measured Lumbar puncture Participants will have follow-up visits for 5 years. They will repeat the screening tests plus have urine and stool tested. Participants may be contacted later by phone to see how they are doing.
