Summary

A case-control study was conducted to evaluate the efficacy and mechanism of action of antibody-drug conjugates (ADCs) in lung cancer, utilizing patient-derived organoid (PDO)-immune co-cultures. Focusing on HER2-positive and TROP2-positive non-small cell lung cancer (NSCLC) cases, ADC candidates were screened for in vitro activity based on organoid-immune interaction models.

Key assessments included:

Tumor killing efficiency, assessed by dose-response relationships; Drug internalization (cellular uptake), as a measure of penetration into cancer cells; Antibody-dependent cellular cytotoxicity (ADCC) and bystander effect, with negative control targets employed to delineate specificity; Single-cell RNA sequencing, to profile transcriptional alterations at single-cell resolution.

Data demonstrated distinct ADC responses correlating with target expression and immune microenvironment features. The integrated approach provided cell-based evidence of ADC potency and revealed mechanistic insights-including immune-mediated cytotoxicity pathways and intracellular trafficking-supporting the rational design of clinical trials. These findings established a foundation for precision immunotherapy strategies and offered a mechanistic rationale for patient selection in HER2/TROP2-positive lung cancer.

Conditions

  • HER2 Positive OR TROP2 Positive Non-Small Cell Lung Cancer

Interventions

DRUG

Antibody-drug conjugate (ADC) combination therapy

In a co-culture system of tumor patient-derived organoids (PDOs) and autologous immune cells, at least ten drug combinations comprising antibody-drug conjugates (ADCs) plus tyrosine kinase inhibitors (TKIs) or immune checkpoint blockers (ICBs) were employed to screen for ADCs with sensitivity against the tumor PDOs. The ADCs selected for evaluation included: Trastuzumab deruxtecan for injection (intravenous) Trastuzumab emtansine for injection (intravenous) Sacituzumab govitecan for injection (intravenous)
