Details and patient eligibility

About

The primary objective of this study is to determine the overall response rate of KW-0761 for the treatment of patients with relapsed or refractory PTCL. KW-0761 targets CCR4. CCR4 is the receptor for macrophage derived chemokines MDC/CCL22 and TARC/CCL17. Chemokines are considered to play a role both in the recruitment of immune and inflammatory cells for anti-tumor response and in the selective homing of neoplastic B and T cells.

Full description

PTCL is a rare and heterogeneous disease that remains difficult to diagnose and treat. In the majority of PTCL subtypes, patients are of older age (>60 years) and present with advanced stage disease.With the exception of the ALCL-ALK-positive subtype that responds well to CHOP combined chemotherapy, most PTCL subtypes become refractory even to aggressive chemotherapy regimens or relapse. Overall survival of PTCL patients is poor compared with that of aggressive B-cell lymphomas.Thus, novel and effective therapies are needed.KW-0761(mogamulizumab) is a defucosylated, humanized, IgG1 mAb with enhanced antibody dependent cellular cytotoxicity (ADCC)that binds to CCR4, a molecule that is suggested to be significantly involved in patients with PTCL.
