Study of Camrelizumab in Combination With Apatinib Mesylate Plus Albumin-bound Paclitaxel and Cisplatin as the First Line Treatment of Recurrent or Metastatic, UnresectableHead and Neck Squamous Cell Carcinoma

This is a prospective, open-labelled study to evaluate the efficacy and safety of Camrelizumab in Combination With Apatinib mesylate Plus Albumin-bound paclitaxel and cisplatin as the First Line Treatment of Metastatic or Recurrent, UnresectableHead and Neck Squamous Cell Carcinoma.
