Safety of bronchial artery infusion immunotherapy: from comparative analysis in beagle canines to clinical validation.

ABSTRACT:

Background

Despite advancements in systemic chemotherapy and immune checkpoint inhibitors (ICIs), advanced non-small cell lung cancer (NSCLC) continues to exhibit poor prognosis, underscoring an urgent need for safer and more effective therapeutic strategies. This study investigates the safety profile and biological effects of bronchial arterial infusion (BAI)-administered anti-PD-1 monoclonal antibody (aPD-1 mAb) using a preclinical beagle model and a clinical cohort of advanced NSCLC patients.

Methods

In preclinical evaluations, male beagles (n = 3/group) were randomized to receive 5 mg/kg aPD-1 mAb via BAI or intravenous routes (Venous group). Safety assessments included longitudinal imaging, biochemical analyses, and histopathological evaluation. Clinically, patients wit
