Drug Delivery to the Brain

Margareta Hammarlund-Udenaes (PhD) is a Professor in Pharmacokinetics and Pharmacodynamics (PKPD) at Uppsala University and the Head of the Translational PKPD Group. Her research is focused at studying pharmacokinetic aspects of BBB transport of drugs in relation to CNS effects, which has led to the development of new concepts and methods within the BBB transport area, focusing on unbound drug relationships. Dr. Hammarlund-Udenaes is an Associate Editor of Pharmaceutical Research and a member of the Editorial Advisory Board of Journal of Pharmaceutical Sciences and Fluids and Barriers of the CNS. She became an American Association of Pharmaceutical Scientists' Fellow in 2005. She is a frequent lecturer at conferences and in drug industry. Her company gives courses and advice in PKPD and BBB transport issues. She co-founded and has co-chaired several of the International Symposia on Microdialysis, and she is the Chair of the 'Barriers of the CNS' Gordon Conference in 2014. Elizabeth C.M. de Lange (PhD) is Head of the Target Site Equilibration Group at the Division of Pharmacology of the Leiden Academic Center for Drug Research (LACDR). Her research program focuses on the development of generally applicable predictive PKPD models on CNS drugs using advanced in vivo animal models and mathematical modeling techniques, with a number of recent successes. She is an Editorial Board member of the journal Fluids and Barriers of the CNS, and an Editorial Advisory Board member of the Journal of Pharmaceutical Sciences and of Pharmaceutical Research. She has been the cofounder and (co-)Chair at the 1st, 2nd and 5th International Symposia on Microdialysis, and has been the Chair of the 9th International Conference on Cerebral Vascular Biology (2011). Among many other functions within the American Association of Pharmaceutical Scientists, she is the 2014 Chair of the Annual Meeting Programming Committee. With her company "In Focus" (www.infocus-ecmdelange.nl) she provides courses, training and advice on microdialysis, pharmacokinetics, BBB transport, intra-brain distribution and PKPD relationships. Robert G. Thorne (PhD) is a Denali Fellow at Denali Therapeutics and an Adjunct Associate Professor in the Department of Pharmaceutics at the University of Minnesota. His research as a laboratory head has focused primarily on CNS barrier sites and diffusive and convective transport within the extracellular and perivascular spaces of the central nervous system. A consistent theme in his work has been to leverage knowledge of physiology, CNS structure, and the blood-brain and blood-cerebrospinal fluid barriers along with a variety of experimental methods in order to identify how best to deliver antibodies, oligonucleotides, and gene therapy vectors to the brain following administration to the circulation or via the various different central routes (e.g. intrathecal, intranasal and intraparenchymal). Prior to joining Denali, he worked full time for over 10 years as a member of the faculty at two academic institutions, first with the Department of Physiology and Neuroscience at New York University School of Medicine and next with the Division of Pharmaceutical Sciences at the University of Wisconsin-Madison. Now at Denali, his focus has broadened to encompass all potential strategies for large molecule delivery to the brain, including brain endothelial cell receptor-targeted approaches for crossing the blood-brain barrier after systemic administration. He was elected in 2017 to serve as the Vice President (President-elect) of the International Brain Barriers Society, a global organization responsible for leadership and directing worldwide initiatives related to the CNS barriers and drug delivery fields. Dr. Thorne previously chaired the 2016 'Barriers of the CNS' Gordon Research Conference and co-chaired the 2019 AAPS-IBBS Workshop on 'Novel Approaches Targeting Brain Barriers for Effective Delivery of Therapeutics.'
