Novartis Pharma AG has entered into an option and collaboration agreement with BioArctic AB to develop an antibody treatment for a neurodegenerative disorder that takes advantage of the Swedish company’s technology for helping drugs cross the blood-brain barrier. The target for the prospective treatment has not been disclosed. But the transporter technology is public and is being used by BioArctic in multiple projects. It is based on the transferrin receptor, a protein responsible for the delivery of iron to cells. This can also enable antibody drugs to cross the barrier.
