Summary

This study is a open, multi-center phase II clinical study to explore the efficacy, safety and pharmacokinetic/pharmacodynamic characteristics of SI-B001+SI-B003 combined with platinum-based chemotherapy as first-line treatment in patients with recurrent or metastatic head and neck squamous cell carcinoma.
