Clinical Trial Summary

This phase I trial studies the side effects of polatuzumab vedotin when given with combination chemotherapy for the treatment of patients with untreated large B-cell lymphoma that grows and spreads quickly and has severe symptoms (aggressive). Polatuzumab vedotin is a monoclonal antibody, polatuzumab, linked to a toxic agent called vedotin. Polatuzumab attaches to CD79B positive cancer cells in a targeted way and delivers vedotin to kill them. Drugs used in combination chemotherapy such as etoposide, 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. Rituximab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. 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 polatuzumab vedotin in addition to etoposide, prednisone, cyclophosphamide, doxorubicin and rituximab may help treat patients with aggressive large B-cell lymphoma.


Clinical Trial Description

OUTLINE: Patients receive rituximab intravenously (IV) on day 1, polatuzumab vedotin IV on day 1, prednisone orally (PO) twice daily (BID) on days 1-5, etoposide IV on days 1-4, doxorubicin IV on days 1-4, and cyclophosphamide IV on day 5. Patients also receive filgrastim subcutaneously (SC) 24-72 hours after the last dose of each treatment cycle. Treatment repeats every 21 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. After the completion of study treatment, patients are followed periodically for up to 5 years. ;
