About

This is a non-randomized phase 1, open-labeled clinical study, 1-arm, single center, to observe efficacy and safety of chemotherapy plus PD-L1 antibody Toripalimab every 21 days for 2 cycles as induction regimen in locoregionally-advanced laryngo-hypopharyngeal squamous cell cancer patients.

Full description

Locoregionally advanced laryngo-hypopharyngeal squamous cell cancer patients have the demand of laryngo-preservation. Induction chemotherapy (FP) combined with Toripalimab (a humanized IgG4 monoclonal antibody against PD-1) will be given. This regimen will be given every 21 days for 2 cycles. Radiological examinations and PET(FDG/FAPI) examinations pre/post-treatment will be administrated for response evaluation.

Enrollment: 20 estimated patients

Sex: All

Ages: 18+ years old
