A Study of HX008 Plus LP002 for the Treatment of Patients With Advanced Melanoma
February 12, 2021 updated by: Taizhou HoudeAoke Biomedical Co., Ltd.
A Phase I Study of Tolerance and Pharmacokinetics of HX008 (a Humanized Monoclonal Antibody Targeting PD-1) Plus LP002 (a Humanized Monoclonal Antibody Targeting PD-L1) in Patients With Locally Advanced or Metastatic Melanoma Who Have Experienced Progressed Disease in Previous Anti-PD-1 or PD-L1 Therapy.
The subsequent treatment choices for the patients with advanced melanoma, who have failed the immune checkpoint inhibitor therapy of single agent.
Evidences showed that PD-1 and PD-L1 signalling pathways are not redundant.
Blocking both of them could produce synergistic effect.
HX008 and LP002 are humanized monoclonal antibodies targeting PD-1 on T cells and PD-L1 on tumor cells respectively.
In this study, participants with locally advanced or metastatic melanoma who have failed previous anti-PD-1 or PD-L1 will be administrated with HX008 plus LP002.
The safety and preliminary efficacy will be evaluated.
