PRIMARY OBJECTIVE:~I. To determine the safest and most tolerable dose and schedule of lenalidomide to combine with etoposide, prednisone, vincristine sulfate (Oncovin), cyclophosphamide, and doxorubicin hydrochloride (hydroxydaunorubicin hydrochloride) (EPOCH) chemotherapy in adult T-cell leukemia-lymphoma (ATL/ATLL).~SECONDARY OBJECTIVES:~I. To observe and record anti-tumor activity. II. To determine if lenalidomide and EPOCH activity results in significant improvement in remission rates and duration of remissions as compared to historical controls.~III. To determine if lenalidomide and EPOCH activity correlates with T-cell receptor (TCR) pathway gene mutational spectrum.~IV. To determine effects of lenalidomide and EPOCH on human T-cell leukemia virus type 1 (HTLV-1) proviral deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) loads.~V. To determine effects of lenalidomide and EPOCH on HTLV-1 clonality.~OUTLINE: This is a dose-escalation study of lenalidomide.~INDUCTION THERAPY: Patients receive lenalidomide orally (PO) once daily (QD) on days 1-14 of 21 day cycles or days 1-21 or 1-28 of 28 day cycles. Patients also receive doxorubicin hydrochloride intravenously (IV) continuously on days 1-4, vincristine sulfate IV continuously on days 1-4, etoposide IV continuously on days 1-4, prednisone PO on days 1-5, and cyclophosphamide IV over 1-4 hours on day 5. Treatment repeats every 21 or 28 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity.~MAINTENANCE THERAPY: Patients with complete response (CR), partial response (PR), or stable disease (SD) may receive up to 2 additional cycles of lenalidomide, doxorubicin hydrochloride, vincristine sulfate, etoposide, prednisone, and cyclophosphamide at the discretion of the investigator and/or up to an additional 2 years of lenalidomide in the absence of disease progression or unacceptable toxicity.~After completion of study treatment, patients are followed up for 2 years.
This phase I trial studies the side effects and best dose of lenalidomide when given together with usual combination chemotherapy (etoposide, prednisone, vincristine sulfate [Oncovin], cyclophosphamide, and doxorubicin hydrochloride [hydroxydaunorubicin hydrochloride], or EPOCH) in treating adult T-cell leukemia-lymphoma. Lenalidomide may help shrink or slow the growth of adult T-cell leukemia-lymphoma. Drugs used in chemotherapy, such as etoposide, vincristine, cyclophosphamide, and doxorubicin, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Anti-inflammatory drugs such as prednisone lower the body's immune response and are used with other drugs in the treatment of some types of cancer. Giving lenalidomide and the usual combination chemotherapy may work better in treating adult T-cell leukemia-lymphoma compared to the usual combination chemotherapy alone.
