Subarachnoid haemorrhage

I have an interest in the blood-brain barrier and the effect of extracellular haemoglobin on the brain. Together with Diederik Bulters, neurovascular surgeon, we are designing early phase clinical studies of intraventricular haptoglobin as a novel treatment for subarachnoid haemorrhage, on the basis of strong signals of efficacy in preclinical models. I have joined this research database since I strongly believe that collaboration between investigators working with intrathecal drug administration will benefit clinical development of this drug delivery route.
