Evaluating the Preliminary Efficacy and Safety of JS207 in NSCLC After Progression Following Platinum-based Chemotherapy and Immunotherapy

A Phase II Study of JS207 (PD-1/VEGF Dual Antibody) in Combination With or Without JS004 or Docetaxel in Advanced Non-small Cell Lung Cancer With Disease Progression During or After the Treatment of Platinum-based Chemotherapy and Immunotherapy

This is a multiple-arm, open phase II clinical trial evaluating the safety, tolerability,and preliminary efficacy of JS207 in NSCLC after progression following Platinum-based chemotherapy and immunotherapy.

Inclusion Criteria:

1. Histologically or cytologically confirmed locally advanced (stage IIIB/IIIC) NSCLC that is not amenable to radical surgery or radical radiochemotherapy, or Metastatic or recurrent NSCLC.
2. Subjects with unresectable locally advanced or metastatic or recurrent NSCLC who have failed first-line treatment with PD-1/PD-L1 inhibitors combined with platinum-based doublet chemotherapy (excluding docetaxel); or who have failed sequential first- and second-line treatment with PD-1/PD-L1 inhibitors followed by platinum-based doublet chemotherapy (excluding docetaxel).
3. Subjects must have at least one measurable lesion according to RECIST v1.1.

Exclusion Criteria:

1. Histopathologically or cytopathologically confirmed to have combined neuroendocrine component.
2. Sensitivity mutation of EGFR or ALK fusion.
3. Tumor encircles important blood vessels or has obvious necrosis and air space, and the investigator considers that it may cause hemorrhage risk.
