Polatuzumab Vedotin and Chemotherapy for Aggressive Large B-cell Lymphoma

This study is looking at the side effects of polatuzumab vedotin when given with combination chemotherapy, with or without glofitamab, for people with aggressive large B-cell lymphoma that hasn't been treated before. This type of lymphoma grows and spreads quickly. Polatuzumab vedotin is a treatment that targets specific cancer cells (CD79B positive) and delivers a medicine to kill them. Glofitamab is another treatment that may stop cancer cells from growing and spreading. The study aims to see how safe these treatments are. You may be eligible if you are 18 or older and have untreated aggressive B-cell large-B cell lymphoma with certain features. The study plans to enroll 56 participants, but its current status is unclear.

Study design
This is an interventional study with two arms. Participants receive different combinations of treatments.
What's involved
Participants will receive treatments intravenously (IV) and orally (PO) over cycles of 21 days for up to 6 cycles. They will also have various scans, biopsies, and blood tests throughout the study.
Compensation
Not stated in the trial record.
Follow-up
Adverse events will be measured for up to 30 days after the last dose of polatuzumab or first administration of alternate therapy.

Eligibility criteria

Inclusion

Untreated aggressive B-cell large-B cell lymphoma (non-Hodgkin lymphoma) with adverse features that may predict sub-optimal response to rituximab-cyclophosphamide, doxorubicin (hydroxydaunorubicin), vincristine (Oncovin), prednisone (R-CHOP) and in the opinion of the investigator would be treated with DA-EPOCH-R as standard of care. 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. Eligible histologies based on 2016 World Health Organization (WHO) classification include:
High grade B-cell lymphoma with MYC and BCL2 and/or BCL6 translocations
High grade B-cell lymphoma, not otherwise specified (NOS)
Diffuse large B-cell lymphoma (DLBCL) NOS

Serum total bilirubin =\< 1.5 X upper limit of normal (ULN) (Patients with documented Gilbert disease may be enrolled if total bilirubin =\< 3.0 x ULN)
Direct bilirubin =\< ULN for subjects with total bilirubin levels \> 1.5 ULN
Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase \[SGOT\]) and alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase \[SGPT\]) =\< 2.5 X ULN OR =\< 5 X ULN for subjects with liver involvement
International Normalized Ratio (INR) or Prothrombin Time (PT) =\< 1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or partial thromboplastin time (PTT) is within therapeutic range of intended use of anticoagulants
Activated partial thromboplastin time (aPTT) =\< 1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants, or subject is shown to have an antiphospholipid antibody on workup
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
