HTLV-1 Infection

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.

This phase 2b, open-label, randomized controlled trial evaluates the efficacy and safety of dolutegravir (DTG) alone versus dolutegravir combined with tenofovir disoproxil fumarate (TDF) in individuals with HTLV-1 infection and associated clinical manifestations. The primary objective is to compare changes in HTLV-1 proviral load at 24 and 48 weeks. Secondary outcomes include clinical, functional, immunological, and quality-of-life measures.
