A Prospective Trial Evaluating the Efficacy and Tumor Immune Microenvironment Remodeling Induced by SFI Plus PD-1 Inhibitors and PBC in Resectable NSCLC

This prospective, single-center clinical trial will enroll 30 treatment-naïve patients with locally advanced, resectable stage II-IIIA non-small cell lung cancer (NSCLC) to receive neoadjuvant Shenqi Fuzheng Injection (SFI) in combination with a PD-1 inhibitor and platinum-based chemotherapy. The primary endpoint is the pathological complete response (pCR) rate, while secondary endpoints include the major pathological response (MPR) rate and event-free survival (EFS). Furthermore, single-cell and spatial transcriptomics will be employed to dynamically track alterations in the immune regulatory network within the tumor microenvironment (TME) pre- and post-SFI administration. This approach aims to elucidate how SFI remodels the TME immune landscape and to uncover its potential advantages in improving clinical outcomes. Additionally, we will investigate the synergistic effects of SFI combined with PD-1 blockade and platinum-based chemotherapy, with the ultimate goal of advancing the integration of traditional Chinese medicine into the therapeutic paradigm for resectable NSCLC.
