Overview

A combination therapy consisting of toripalimab (an anti-PD-1 monoclonal antibody), S1 (an oral fluoropyrimidine anticancer agent), and albumin-bound paclitaxel (nab-paclitaxel, a solvent-free formulation of paclitaxel). This regimen combines immunotherapy with chemotherapy to potentially enhance antitumor activity. Toripalimab binds to the PD-1 receptor with high affinity, inducing endocytosis and reducing PD-1 expression on cell membranes. Albumin-bound paclitaxel utilizes albumin as a natural carrier to improve tumor targeting and reduce toxicity compared to conventional paclitaxel. S1 is an oral fluoropyrimidine that combines tegafur with modulators.
