Clinical Research of ROBO1 Specific CAR-NK Cells on Patients With Solid Tumors

Study Overview
=================
Brief Summary
-----------------
Immunotherapy has become the major breakthrough and the most promising treatment, with the host of development of tumor biology, molecular biology and immunology. We have developed anti-ROBO1 CAR-NK cells that can target tumor cells highly expressing ROBO1. The purpose of this study is to evaluate the safety and effectiveness of cell therapy using ROBO1 CAR-NK cells to treat solid tumors.
