Study Arms (1)

Mogamulizumab + DA-EPOCH or CHOEP

EXPERIMENTAL

All subjects are scheduled to receive six cycles of DA-EPOCH + Mogamulizumab Cycle 1: Mogamulizumab on days 1,8,15, of a 21-day cycle with DA-EPOCH on day 1. Cycles 2 to 6: Mogamulizumab on day 1 with DA-EPOCH or CHOEP Mogamulizumab will be administered modified to a 21-day cycle in combination with chemotherapy. Subjects will receive 1.0 mg/kg of mogamulizumab as an IV infusion over at least 1 hour on Days 1, 8, 15 of the first cycle and Day 1 for the subsequent cycles. This is based on prior studies with mogamulizumab in combination of chemotherapy.(15) This dosing regimen will ensure the first 4 doses are given weekly at a dose of 1 mg/kg. Subsequent dosing on a 21-day schedule to coincide with the frequency of administration of DA-EPOCH or CHOEP to allow for simpler co-administration of the study drugs. In addition, this study proposes to leverage the immunomodulatory role of mogamulizumab, the dosing for this has not been previously established or explored.

Drug: MogamulizumabDrug: DA-EPOCH ProtocolDrug: CHOEP protocol

Interventions

Mogamulizumab is a defucosylated, humanized, monoclonal antibody (Mab) with enhanced antibody dependent cellular cytotoxicity that binds to CCR4. The lack of fucose results in the antibody eliciting more potent ADCC than conventionally produced antibodies. Mogamulizumab is devoid of complement dependent cytotoxicity. CC Chemokine receptor 4 is over expressed on the surfaces of cells comprising several T-cell malignancies such as peripheral T-cell lymphoma (PTCL) and CTCL and is a potential target for anti-neoplastic therapy in these disorders.

Also known as: Poteligeo
Mogamulizumab + DA-EPOCH or CHOEP

EPOCH is an intensive chemotherapy regimen intended for treatment of aggressive non-Hodgkin's lymphoma.

Also known as: dose-adjusted etoposide, doxorubicin, and cyclophosphamide with vincristine and prednisone
Mogamulizumab + DA-EPOCH or CHOEP

CHOEP is an intensive chemotherapy intended for treatment of aggressive t-cell lymphoma.

Also known as: dose-adjusted Cyclophosphamide, Hydroxydaunorubicin, Oncovin, Etoposide, Prednisone
