Immune recognition

The chair is aimed at increasing understanding of the molecular mechanisms of immune recognition and stimulate the translation of research findings into applications, therapies and valorisation. 

Paul Parren’s research focusses on the studying antibody biology at the molecular level and translating these findings to applications in the clinic. These applications encompass (clinically) validated innovated antibody technologies that allow antibody therapeutics to be developed in novel formats, thereby providing novel treatment modalities that aim to increase treatment efficacy, ultimately leading to cures for life-threatening and debilitating diseases.

Academic career

Paul Parren studied Biology at the University of Amsterdam with a B.S. in Chemical Biology in 1984 and a M.Sc. in Experimental Oncology (cum laude) in 1987. He did his graduate work in the department of Autoimmune Diseases at the Central Laboratory of the Netherlands Red Cross Blood Transfusion Service in Amsterdam studying crosstalk between recombinant (human) antibodies and innate effector mechanisms with Prof. Lucien Aarden. On June 12, 1992 he received a PhD from the University of Amsterdam after he defended his thesis entitled: “Recombinant antibodies to CD3”. Next, he was a Postdoc at Baxter Diagnostics in Miami, FL where he studied recombinant T-cell receptors and a Postdoc, Assistant Professor and Associate Professor in the department of Immunology at The Scripps Research Institute in La Jolla, California, where he interrogated the human antibody response in protection against viral infections including HIV-1 and Ebola virus. From 2002-2017, he served in the positions of Vice President, Senior Vice President and Scientific Director at the biotechnology company Genmab in Utrecht, where he headed preclinical R&D. Between 2013-2018, he was an Adjunct Honorary Professor of Translational Cancer Research at the University of Southern Denmark in Odense. In 2015, he became a Professor of Molecular Immunology at the Leiden University Medical Center in Leiden, and on 14 September 2018 he spoke his inaugural lecture entitled: “Our immune system: a source of inspiration for innovative drug research”. In 2018, he became head of R&D at the biotech Lava Therapeutics to develop novel bispecific gamma-delta T-cell engagers for cancer therapy. He also provides drug development, patent and investment advice as an independent biotech consultant.

Prof. Parren is dedicated to translate antibody biology and immunotherapy knowledge into innovative therapeutics and technologies. He has a passion for investigating and understanding structure-function relationships and translating the knowledge gained into immunotherapy applications and drug development. He is an inventor of the therapeutic antibodies ofatumumab (Arzerra, Kesimpta) daratumumab (DARZALEX), teprotumumab (Tepezza), tisotumab vedotin (Tivdak) en amivantamab (Rybrevant). Ofatumumab was approved in 2009 for the treatment of Chronic Lymphocytic Leukemia and in 2020 in a subcutaneous formulation for Multiple Sclerosis. Ofatumumab received the Dutch Galenus Prize in 2011 for most innovative new medicine. Ofatumumab (Arzerra) has, for the treatment of cancer, since been transitioned to compassionate use and oncology access programs. Daratumumab was first approved in 2015 for the treatment of Multiple Myeloma. Teprotumumab was approved for the treatment of Active Thyroid Eye Disease (Graves’ orbitopathy in 2020. Tisotumab vedotin (an antibody-drug conjugate) and amivantamab (an EGFR-cMet bispecific antibody) were approved in 2021 by FDA for the treatment of recurrent or metastatic cervical cancer and for metastatic NSCLC with EGFR exon 20 insertion, respectively. Paul Parren further invented and developed several clinically translated technologies aimed at improving antibody therapy, including bispecific antibodies and effector function-enhanced antibodies (DuoBody and HexaBody platforms). The first bispecific antibody product based on the DuoBody technology obtained regulatory approval in 2021. His work has thus far directly led to four therapeutic antibodies that received FDA Breakthrough Therapy designation and ten further therapeutic antibodies in various formats currently in clinical development for the treatment of cancer and Parkinson’s disease.

Prof. Parren supports antibody-related research in the LUMC dept. of Immunology and beyond, with the aim to stimulate the implementation of state-of-the-art antibody technologies in drug development and to innovate, translate and disseminate and valorise (therapeutic) antibody knowledge.

Prizes and honourable appointments

Paul Parren has published extensively both in the scientific as well as the patent literature. He authored over 230 scientific publications with a total of >32,500 citations (Google Scholar). He edited issues of Current Opinion in Immunology (2008 & 2016) and Methods (2014). He in inventor on 60 issued patent families that resulted in 92 US and 56 EU patents and numerous patents in other countries. In total, he is a named inventor on 87 published PCT patent applications. He chaired sessions at 50+ scientific conferences and gave over 200 invited oral presentations at international scientific and business conferences including 15 plenary keynote lectures. In 2017, he received the Utrecht award for excellence in Pharmaceutical Science.

Paul Parren initiated and organized the Dutch Complement Symposium and the European Antibody Engineering and Therapeutics conference
