Treatment (DA-EPOCH, rituximab, JZP458)EXPERIMENTALPatients receive etoposide IV, doxorubicin IV and vincristine IV over 96 hours on days 1-4, cyclophosphamide IV over 1 hour on day 5, prednisone PO BID on days 1-5 of each cycle. In addition, CD20 positive patients receive rituximab IV on day 1 or 5 of each cycle. Patients also receive JZP458 IM every 2-3 days on days 7-21 for up to 7 doses. Cycles repeat every 21 days for up to 8 cycles in the absence of disease progression or unacceptable toxicity. Starting on day 6, 7, or 8, patients also receive pegfilgrastim SC once or filgrastim SC QD until ANC \> 2000/uL past nadir. Patients also undergo blood sample collection and bone marrow collection throughout the study. Additionally, patients with extramedullary disease may undergo CT or PET/CT throughout the study.
