Exploratory Study of NK510 Combined With PD-1 Blockade in the Treatment of Relapsed and Refractory Advanced NSCLC

NK510-06

This study will evaluate the safety and efficacy of NK510 in the treatment of relapsed and refractory advanced NSCLC.NK510 will be administered in combination with PD-1 blockade. Patients are required to undergo a biopsy for confirmation of tumor PD-L1 expression,and EGFR,ROS1,ALK gene must be negative. The safety and efficacy of this treatment will be evaluated.

Allowing selected subjects to inhale or topically use corticosteroids in the absence of active autoimmune diseases; * The virological examination of hepatitis B or hepatitis C during screening meets any of the following criteria: 1. HBsAg positive and peripheral blood HBV-DNA titer detection≥1×10\^3 copies/mL or upper limit of normal value; 2. HCV antibody positive; * Subjects who are known to be allergic or intolerant to PD-1 monoclonal antibody. * Meet any of the following standards: 1. Hematological:Neutrophil count \<1.5×10\^9/L; Platelet count \< 75×10\^9/L; Hemoglobin \< 9 g/dL; 2.
