The overall purpose of the study is to evaluate the biodistribution and target lesion uptake of 89Zr-KN035 in patients with PD-L1 positive advanced solid tumors by using PET imaging. Safety will be observed after 89Zr-KN035 injection, and radiation dosimetry of 89Zr-KN035 will be calculated.
This is a single arm study by using 89Zr-labeled KN035 (89Zr-KN035) PET imaging to evaluate the biodistribution and target lesion uptake of 89Zr-KN035 in patients with PD-L1 positive advanced solid tumors.
