The goal of this clinical trial is to evaluate whether sacituzumab govitecan (TROP2 antibody-drug conjugate) in combination with anlotinib (multi-target tyrosine kinase inhibitor) can improve treatment efficacy and safety in patients with driver gene-negative locally advanced or metastatic non-squamous non-small cell lung cancer (nsq-NSCLC) after failure of first-line immunotherapy combined with platinum-based chemotherapy. The main questions it aims to answer are: Can the combination of sacituzumab govitecan and anlotinib improve progression-free survival (PFS) compared to historical second-line chemotherapy outcomes? What is the objective response rate (ORR) and safety profile of this combination therapy in this patient population? Can baseline multi-omics biomarkers (metabolomics, proteomics, and ctDNA genomics) predict response or resistance to sacituzumab govitecan? If there is a comparison group: This is an exploratory single-arm study, and outcomes will be compared with historical controls of second-line chemotherapy in similar patient populations. Participants will: Receive sacituzumab govitecan combined with anlotinib according to the study treatment schedule Undergo routine imaging evaluations to assess tumor response Provide peripheral blood samples before treatment for metabolomic, proteomic, and ctDNA genomic analyses Be monitored regularly for treatment response and adverse events

Objective Response Rate (ORR) Assessed by Investigator per RECIST v1.1
Timeframe: Up to 2 years (Assessed every 6 weeks for the first 48 weeks, then every 12 weeks thereafter until disease progression or death).
