Abstract

Advances in therapies for breast Cancer with cerebral metastases has been slow, despite this being a common diagnosis, due to limited drug delivery by the blood brain barrier. Improvements in drug delivery for brain metastasis to target the metastases and bypass the blood brain barrier are necessary. In our study, we delivered an inhibitor of Chemokine Receptor 4 by convection enhanced delivery in a hyperosmotic solution to prevent brain metastasis in a mouse model of metastatic breast Cancer. We found the inhibitor limited metastatic disease and more interestingly, the hyperosmotic solution targeted tumor tissue allowing for a higher accumulation of the therapy into tumor tissue. This finding has the potential to improve delivery of chemotherapeutic agents to brain metastases.
