About

This is a single-center, single-arm, phase 2 study to evaluate the efficacy and safety of camrelizumab in combination with cetuximab and chemotherapy as first-line for patients with relapsed/metastastic head and neck squamous cell carcinoma

Full description

Patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC) not amenable to curative-intent therapies have poor survival.

At present, the standard treatment is cetuximab and chemotherapy plus PD-1 inhibitor Regimen.

This study is a phase II, prospective, single arm，single-center study, which requires a total of 40 R/M HNSCC patients. Patients will receive no more than 6 cycles of albumin paclitaxel and cisplatin, repeated every 3 weeks. PD-1 inhibitor will be administered until progression every 3 weeks. Cetuximab will be administered 400 mg/m2 at first dose, following by 250 mg/m2 after first dose until progression, repeated every 3 weeks.

Enrollment: 40 estimated patients

Sex: All

Ages: 18 to 70 years old

Volunteers: No Healthy Volunteers
