About
This phase II trial tests the safety, best dose, and effectiveness of epcoritamab when given with etoposide, cyclophosphamide, vincristine, doxorubicin, prednisone and rituximab (EPOCH-R) for the treatment of patients with aggressive B-cell non-Hodgkin lymphoma. Epcoritamab is a bispecific antibody that can bind to two different antigens at the same time. Epcoritamab binds to CD3, a T-cell surface antigen, and CD20 (a tumor-associated antigen that is expressed on B-cells during most stages of B-cell development and is often overexpressed in B-cell cancers) and may interfere with the ability of cancer cells to grow and spread. Etoposide is in a class of medications known as podophyllotoxin derivatives. It blocks a certain enzyme needed for cell division and DNA repair and may kill cancer cells. Cyclophosphamide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill cancer cells. It may also lower the body's immune response. Vincristine is in a class of medications called vinca alkaloids. It works by stopping cancer cells from growing and dividing and may kill them. Doxorubicin is in a class of medications called anthracyclines. Doxorubicin damages the cell's DNA and may kill cancer cells. It also blocks a certain enzyme needed for cell division and DNA repair. Prednisone is in a class of medications called corticosteroids. It is used to reduce inflammation and lower the body's immune response to help lessen the side effects of chemotherapy drugs. Rituximab is a monoclonal antibody. It binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. The EPOCH-R is administrated as the standard of care treatment. This may help the immune system kill cancer cells. Giving epcoritamab with EPOCH-R may be safe, tolerable, and effective in treating patients with aggressive B-cell non-Hodgkin lymphoma.
Full description
OUTLINE:
Patients receive rituximab intravenously (IV) on day 1, prednisone orally (PO) twice daily (BID) on days 1-5, etoposide IV and doxorubicin on days 1-4 and cyclophosphamide IV on day 5 of each cycle. Patients also receive epcoritamab subcutaneously (SC) on days 8 and 15 of cycle 1, days 1, 8 and 15 of cycles 2-4 and day 1 of cycles 5-6. Cycles repeat every 21 days for 6 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo multigated acquisition (MUGA) scan or echocardiography during screening and receive fludeoxyglucose and undergo positron emission tomography (PET) scan, computed tomography (CT) scan, bone marrow biopsy and aspirate (if needed), and blood sample collection throughout the study.
After completion of study treatment, patients are followed up periodically for up to 5 years.

Inclusion criteria
-
Untreated aggressive large-B cell lymphoma (non-Hodgkin lymphoma) with adverse features that may predict sub-optimal response to R-CHOP and in the opinion of the investigator would be treated with dose adjusted (DA)-EPOCH-R as standard of care. Subjects must be planned to receive full course (6 cycles) chemoimmunotherapy as per clinical standard of care. 1 prior cycle of chemoimmunotherapy may be allowed. Composite lymphomas are not excluded provided that the subject has not received 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
- Primary mediastinal B-cell lymphoma
- T-cell/histiocyte-rich large-B-cell lymphoma
- Epstein Barr virus (EBV) + DLBCL, NOS

- Creatinine clearance should be calculated per institutional standard
-
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) OR direct bilirubin ≤ ULN for subjects with total bilirubin levels > 1.5 ULN

International Normalized Ratio (INR) ≤ 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 prothrombin Time (PT) ≤ 1.5 X ULN unless subject is receiving anticoagulant therapy
-
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 study treatment. 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
-
For women of childbearing potential, a negative serum pregnancy test result during screening period. Women who are considered not to be of childbearing potential are not required to have a pregnancy test
-
For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use a condom, and agreement to refrain from donating sperm, as defined below: With female partners of childbearing potential or pregnant female partners, men must remain abstinent or use a condom during the treatment period and for at least 6 months after the last treatment. 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

Prior therapy for large B-cell lymphoma except for patients who require lymphoma symptom control during screening may receive steroids and/or 1 cycle of chemoimmunotherapy in the following manner:
- Up to 30 mg/day of prednisone or equivalent may be used for lymphoma symptom control during screening, including prior to finalization of staging (not included as part of pre-phase treatment). If glucocorticoid treatment is urgently required at higher doses for lymphoma symptom control prior to the start of study treatment, tumor assessments must be completed prior to initiation of > 30-100 mg/day of prednisone or equivalent. Prednisone > 30-100 mg/day or equivalent may be given for a maximum of 7 days as a pre-phase treatment. If patients exceed the allowed dosing of corticosteroids, patients may still be eligible for the study provided that baseline imaging is performed (or repeated) after completion of the course of higher dose of steroids. Allowed corticosteroid dosing resets from the point of imaging forward and patients who do not exceed the allowed corticosteroid dosing from the point of imaging until initiation of study treatment may enroll. A maximum of 1 cycle of chemoimmunotherapy is allowed if needed for urgent disease stabilization if patient had staging PET/CT and LVEF evaluation prior to chemoimmunotherapy; in this situation patients will receive therapy on study starting with C1D8 epcoritamab provided the next cycle of EPOCH-R chemotherapy will not be delayed by > 7 days
