AAV Vector Shedding Assay— Best Practices in Clinical Gene Therapy Method Development

Life Sciences, Clinical Trials, Laboratory Technology, Cell and Gene Therapy,
  • Tuesday, June 20, 2023

Gene therapies have demonstrated to be life-changing therapies for many devastating diseases. The drug development path is not always straightforward and regulatory guidance is often vague about the details of some requirements. One of the requirements in clinical development is to monitor vector shedding to control the potential environmental risk associated with the therapy. The assay read-out is qualitative, providing the sponsor and investigator with the relevant information about vector-shedding clearance after therapy. A sensitive and reliable method is needed in several different matrices, usually including blood, plasma, faeces, semen, urine and saliva. This webinar will cover unique requirements and challenges in developing vector shedding assays like the AAV shedding assay, with applications.

Join this webinar for a review of best practices for developing a suitable qPCR-based vector shedding assay and how that data can be used and interpreted during the clinical study.

Johannes Stanta, PhD, Global Director of Molecular & Cellular Biology (MCB), Celerion

Johannes Stanta, PhD, works at Celerion as the Global Director of Molecular & Cellular Biology (MCB) being in charge of the Lincoln, NE and Zürich, Switzerland MCB laboratories at Celerion, INC. In this role, Johannes strengthens Celerion’s service offering with GLP and GCP compliant molecular and cell biology testing to support the development of new modality therapies, such as cell and gene therapies. He previously worked at Freeline Therapeutics as Director of Bioanalysis where he has the overall bioanalytical responsibility of several gene therapy clinical trials, including the companion diagnostic analytical and clinical development. He previously worked in senior scientific leadership roles in bioanalysis and clinical laboratory at LabCorp and Hammersmith Medicines Research. He received his PhD from the University of Cambridge, focusing on the discovery of diagnostic biomarkers for neuropsychiatric disorders. He has hands-on industry experience in small and large molecule bioanalytical assay development, validation and sample analysis, supporting clinical and non-clinical programs and is also leading the European Bioanalysis Forum’s Cell and Gene Therapy interest group where Bioanalytical labs across Europe share their bioanalytical challenges and best practices.
