The blood-brain barrier blocks over 98% of small-molecule oncology drugs. Non-invasive low-intensity focused ultrasound paired with circulating microbubbles opens localized endothelial junctions for 6 hours, delivering a 5.4-fold increase in antibody concentrations inside tumors.
Overcomes the central physical barrier preventing systemic monoclonal antibodies from treating glioblastoma.
Regulatory frameworks and infrastructure readiness remain critical.
By 2030, MRI-guided FUS permeabilization will be routine clinical protocol preceding central nervous system chemotherapy.
