About
This phase I trial studies the side effects of polatuzumab vedotin when given with combination chemotherapy with or without glofitamab 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. Glofitamab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). 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 combination chemotherapy with or without glofitamab may help treat patients with aggressive large B-cell lymphoma.
Full description
OUTLINE: Patients are assigned to 1 of 2 arms.
ARM A (CLOSED TO ACCRUAL 05/23/2024): 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. Patients undergo multigated acquisition (MUGA) scan or echocardiography during screening and fludeoxyglucose (FDG) positron emission tomography (PET), computed tomography (CT) scan, bone marrow biopsy and aspiration and blood sample collection throughout the study.
ARM B: Patients receive rituximab IV on day 1, polatuzumab vedotin IV on day 1, prednisone PO BID on days 1-5, etoposide IV on days 1-4, doxorubicin IV on days 1-4, and cyclophosphamide IV on day 5. Starting with cycle 2, patients also receive glofitamab, over 4 hours, on day 1 and 8 of cycle 2 and day 1 of subsequent cycles. Treatment repeats every 21 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo MUGA scan or echocardiography during screening and FDG PET, CT scan, bone marrow biopsy and aspiration and blood sample collection throughout the study.
After the completion of study treatment, patients are followed periodically for up to 5 years.

Subjects must be planned to receive full course (6 cycles) chemoimmunotherapy as per clinical standard of care. Composite lymphomas are not excluded provided that the subject has not receive prior systemic therapy for the indolent component and would receive DA-EPOCH-R as the standard of care regimen for the aggressive component.

For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive methods that result in a failure rate of =< 1% per year during the treatment period and for at least 12 months after the last dose of EPCH-R, 9 months after the last dose of polatuzumab, 2 months after the last dose of glofitamab (Arm B participants), or 3 months after the last dose of tocilizumab (if applicable), whichever is longer. Women must refrain from donating eggs during this same period. A woman is considered to be of childbearing potential if she is post-menarcheal, has not reached a postmenopausal state (=<12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus). The definition of childbearing potential may be adapted for alignment with local guidelines or requirements. Examples of contraceptive methods with a failure rate of =<1% per year include bilateral tubal ligation, male sterilization, hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices. The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or post-ovulation methods) and withdrawal are not acceptable methods of contraception

Men must refrain from donating sperm during this same period. The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of preventing drug exposure. Male patients considering preservation of fertility should bank sperm before study treatment
