  • Josbert M. Metselaar, Pharm D, MIRA Institute, Department of Targeted Therapeutics, University of Twente, Enschede, The Netherlands. Josbert M. Metselaar (Rotterdam, July 6th 1971) obtained an MSc degree in Pharmaceutical Sciences in 1995 and a Pharm D (Doctor of Pharmacy) degree in 1998, both at Utrecht University. During his study, he completed a research internship in pharmacology and PK/PD modeling at the Department of Pharmaceutics, University of Florida, USA. In 1999, he started his PhD at the Department of Pharmaceutics and the Department of Immunology Veterinary Medicine in Utrecht within the scope of a large academic research collaboration funded by the Japanese pharmaceutical company Yamanouchi (nowadays Astellas). He studied novel targeted formulations of anti-inflammatory compounds in autoimmune diseases. After completing his PhD in 2003 and a postdoctoral fellowship in the same field of research in 2005, he decided to focus on translating his academic accomplishments into novel clinical and industrial investigational products. To this end, he founded his own university spin off company Enceladus Pharmaceuticals, with which he raised significant funding over the years.

He is also a professor of immunology and biology at the University of Miskolc and founder and CEO of an immune toxicology contract research biotech company, SeroScience Ltd., Hungary. During his 40-year professional career, he has held various junior, senior scientific and (guest) professor positions in Hungary and abroad, mainly in the United States, where he lived for 21 years. His research on various themes in hematology, membrane biology and immunology has resulted in over 120 papers and many book chapters, patents and a book titled The Complement System: Novel Roles in Health and Disease (Kluwer, 2004). Three fields stand out where he has been most active: artificial blood, liposomes and the complement system. His original works from the late 1990s led to the “CARPA” concept, i.e. that complement activation underlies numerous (nano)drug-induced hypersensitivity (infusion) reactions.

Complement activation-related pseudoallergy (CARPA) is a hypersensitivity reaction occurring upon intravenous administration of numerous liposomal therapeutics, other nonbiological complex drugs and biologicals. It has a complex molecular and cellular mechanism that involves the production, actions and interactions of numerous vasoactive mediators in blood, including thromboxane A2 (TXA2). This short review focuses on the latter eicosanoid: its role in CARPA, effects underlying some of the symptoms and experimental evidence for its rate-limiting role in pulmonary hypertension in pigs. Animal experiments and recent clinical observations suggest that the cyclooxygenase blocker indomethacin may represent an effective new approach to prevent liposome-induced CARPA, lending clinical relevance to better understand the involvement of TXA2 and other eicosanoids in this adverse immune effect.
