Summary

The study is being conducted to to explore the reasonable dosage and evaluate the efficacy, safety and tolerability of HLX43 (Anti-PD-L1 ADC) in Patients with Recurrent or Metastatic Head and Neck Squamous Cell Carcinoma (HNSCC)

Conditions

  • Carcinoma of Head and/or Neck

Interventions

DRUG

HLX43 DOSE 1

Dose 1; HLX43 is an anti-PD-L1 monoclonal antibody conjugated with a novel high potency DNA topoisomerase I (topo I) inhibitor, with a drug-antibody-ratio (DAR) of 8.

DRUG

HLX43 DOSE 2

Dose 2; HLX43 is an anti-PD-L1 monoclonal antibody conjugated with a novel high potency DNA topoisomerase I (topo I) inhibitor, with a drug-antibody-ratio (DAR) of 8.

DRUG

HLX43 DOSE 3

Dose 3; HLX43 is an anti-PD-L1 monoclonal antibody conjugated with a novel high potency DNA topoisomerase I (topo I) inhibitor, with a drug-antibody-ratio (DAR) of 8.

DRUG

HLX43 DOSE 2 + HLX10

HLX43 is an anti-PD-L1 monoclonal antibody conjugated with a novel high potency DNA topoisomerase I (topo I) inhibitor, with a drug-antibody-ratio (DAR) of 8. HLX10 is a humanized anti-PD-1 monoclonal antibody that functions as an immune checkpoint inhibitor

DRUG

HLX43 DOSE 3 + HLX10

HLX43 is an anti-PD-L1 monoclonal antibody conjugated with a novel high potency DNA topoisomerase I (topo I) inhibitor, with a drug-antibody-ratio (DAR) of 8. HLX10 is a humanized anti-PD-1 monoclonal antibody that functions as an immune checkpoint inhibitor.

DRUG

HLX43 DOSE 2 + HLX10 + HLX07

HLX43 is an anti-PD-L1 monoclonal antibody conjugated with a novel high potency DNA topoisomerase I (topo I) inhibitor, with a drug-antibody-ratio (DAR) of 8. HLX10 is a humanized anti-PD-1 monoclonal antibody that functions as an immune checkpoint inhibitor. HLX07 is a recombinant humanized anti-EGFR monoclonal antibody.

DRUG

HLX43 DOSE 3 + HLX10 + HLX07
