Immunogenicity Integrated

Who we are

We share a vision of the scientific and regulatory priorities that should be integrated to understand and manage immunogenicity-related risks for successful development of biotherapeutics.

Paul Chamberlain has been directly involved in the development of biopharmaceutical products since 1983, occupying analytical, bioanalytical, product quality control, monoclonal antibody production and regulatory roles. His interest in immunogenicity risk assessment was triggered by experience gained at Amgen in 1998 with PEG-MGDF and then extended through his role as a Development Programs Director at MDS Pharma Services (2001-2007). Paul started submitting the Immunogenicity Risk Assessment module in Clinical Trial Applications from 2004 and then focused on creating an Integrated Summary of Immunogenicity (ISI) to provide a self-standing section of the CTD format that incorporates the multi-disciplinary information required for a balanced regulatory assessment. His first ISI was submitted in 2009 to support the approval of XIAFLEX™, a clostridial collagenase for treatment of Dupuytren’s contracture. The ISI format was subsequently refined and then adopted into EU (2017) and FDA (2019) guidance.

Paul has worked closely with EU and FDA regulators to understand the priorities for regulatory submissions at different stages of the product life cycle, supporting companies directly at Scientific Advice, pre-CTA/IND, End-of-Phase 2, Pre-MAA/BLA submission, Oral Hearings and FDA Advisory Committee meetings.

Annick de Vries, PhD

Annick de Vries, PhD photo

Annick de Vries has a wealth of experience supporting Pharma and Biotech with their immunogenicity bioanalysis. Her career in assay development started at Wyeth, later Pfizer, in 2008. Annick gained most experience as CSO at Sanquin, 2015-2025, where she instigated offering regulated bioanalysis services. Annick and her team, often in collaboration with academic groups and clinicians, published broadly on immunogenicity; from designing immunogenicity tests to real world data.

Annick is KOL in Therapeutics Drug Monitoring (TDM) of biologics and started a bi-annual international symposium and was chair of International Association of TDM and Clinical Toxicology (IATDMCT) TDM of Biologics Committee. Her focus was on how the ADA actually impacts on the PK, which is more often than not quite a limited effect.

Annick is member of the Scientific Advisory Board at Immuneed and the Innovative Health Initiative consortium COMFORT.

Bringing people and knowledge together comes naturally and makes her skilled in the management of collaborative, international, projects. Annick was trained as a neuroscientist (University of Amsterdam) and acquired her PhD in pharmacology at Utrecht University. Annick is now working as independent life sciences consultant and team coach based in Amsterdam, the Netherlands.

Laura began her regulatory affairs career in 2009 as Immunogenicity Program Coordinator and immunogenicity expert at the FDA, while holding a Chemistry, Manufacturing and Controls (CMC) reviewer position. She evaluated the CMC and immunogenicity of multiple therapeutic proteins INDs, license applications (BLAs) and post-approval supplements. She was responsible for the review and Advisory Committee presentation of the immunogenicity of metreleptin (MYALEPT®), currently approved for the treatment of pediatric and adult lipodystrophy.

After 5 years at the FDA, Laura moved to the private sector to broaden her clinical development knowledge acting as Immunology and Biomarkers expert for Sanofi-Genzyme. In this role, she provided strategic support for analytical bioassay development and immunogenicity risk assessment for Enzyme Replacement Therapies (Avalglucosidase alfa – Pompe’s disease), monoclonal antibodies (Sarilumab – KEVZARA® – Rheumatoid Arthritis, and Alirocumab – PRALUENT® - familial hypercholesterolemia and clinical atherosclerotic cardiovascular disease), and gene therapies (Leber’s Congenital Amaurosis), while developing an expertise in biomarker qualification.

Laura then consolidated her CMC expertise acting as regulatory lead for several US and EU regulatory submissions for Sanofi-Genzyme (PRALUENT®), Fresenius Kabi SwissBiosim (Biosimilars), ZioPharm Oncology (autologous CAR-T cell and gene therapies), PokeACell (autologous tumor infiltrating lymphocytes, TILs) and cBio (cell therapy manufacturing).

Laura holds a PhD in Biochemistry and Molecular Biology and has authored various publications in multiple peer-reviewed journals. She is a member of the American Association of Pharmaceutical Scientists (AAPS) and member of the European Immunogenicity Platform (EIP). She is based at the Biopole Campus in Lausanne, Switzerland, here she works as independent regulatory consultant specialized in the preparation of Immunogenicity Risk Assessments (IRA), Integrated Summaries of Immunogenicity (ISI) for FIH and MAA/BLA applications and supporting Scientific Advice, pre-CTA/IND, End-of-Phase 2, Pre-MAA/BLA meetings.
