Novel drug liberates tumour vessels to aid cancer drug delivery

A therapeutic antibody developed by scientists at UCL has been shown to unblock and normalise blood vessels inside cancerous tumours, enabling the more effective delivery of targeted cancer treatments.

The findings in mice, published in the journal MED, are the first to demonstrate that inhibiting the activity of LRG1, a protein produced in many tumorous tissues, liberates disorganised angiogenesis (blood vessel formation) – a leading cause of morbidity in numerous diseases including cancer.
