About

This study is to evaluate the tolerance of albumin paclitaxel combined with apatinib and Camrelizumab in the second-line treatment of advanced gastric cancer to determine the maximum tolerable dose (MTD) of the combination.

Full description

This is a Single arm, open, phase I / II clinical trial. The study was divided into tolerance observation stage (dose exploration stage) and efficacy expansion stage (dose expansion stage).

This study is to evaluate the tolerance of albumin-paclitaxel combined with apatinib and Camrelizumab in the second-line treatment of advanced gastric cancer to determine the maximum tolerable dose (MTD) of the combination.

The secondary objective was to evaluate the safety and efficacy of albumin- paclitaxel in combination with apatinib and Camrelizumab in the second-line treatment of advanced gastric cancer.
