Programmed cell death-1 (PD-1) is a regulatory receptor usually expressed on malignant tumor cells.
It helps tumor cells achieve immune escape by down-regulating the activation of T cells and B cells
.
At present, the use of drugs such as nivolumab and pembrolizumab for PD-1 suppression immunotherapy has been recognized as a major progress in cancer treatment

Mogamulizumab is an anti-CCR4 monoclonal antibody targeting effector regulatory T cells (eTreg)
.
This study aims to clarify the safety, anti-tumor activity and pharmacodynamics of Mogamulizumab combined with the checkpoint inhibitor nivolumab in locally advanced or metastatic solid tumors

This is a multicenter, dose-exploratory (phase I) and dose-expandable (phase II) study, recruiting patients with locally advanced or metastatic solid tumors
.
The phase I trial dose is: Mogamulizumab 1mg/kg·week in the first course of treatment, then changed to 1 mg/kg·2 weeks, plus nivolumab 240 mg/2 weeks
Time to remission (TTR), duration of remission (DOR), progression-free survival (PFS) and overall survival (OS)
Time to remission (TTR), duration of remission (DOR), progression-free survival (PFS) and overall survival (OS)A total of 114 patients received Mogamulizumab (1 mg/kg) + nivolumab (240 mg) treatment, 4 of whom were in phase I and 110 were in phase II.
All were included in the safety and efficacy analysis
.
Mogamulizumab combined with nivolumab showed acceptable safety and tolerability
The objective response rate reached 10.
Mogamulizumab combined with nivolumab did not improve the therapeutic effect of locally advanced or metastatic solid tumors
