11:00 am Morning Break & Refreshments

HARNESSING THE POWER OF ASSAYS TO BETTER MEASURE IMMUNE RESPONSE

12:00 pm Recommendations for the Development of Cell-Based Anti-Viral Vector Neutralizing Antibody Assays

Synopsis

• All humans may be exposed to natural Adeno-Associated Virus (AAV) infections resulting in an immune response against the virus prior to treatment
• High prevalence of pre-existing anti-AAV immunity may be expected, leading to limitation for AAV-based gene therapy treatment
• Recommendations for the development and validation of cell-based anti-AAV NAb detection methods will be presented

12:30 pm Immunogenicity Assay Challenges and Strategies for Gene Therapy

  • Yanmei Lu Senior Director Bioanlytical Sciences, Sangamo Therapeutics

Synopsis

• Evaluate most appropriate methods for developing and validating assays used to detect gene therapy immunogenicity
• Developing assays to better understand gene therapy immunogenicity
• What challenges must be overcome to develop high performing assays

1:00 pm Safety Bioanalytics in LHON Clinical Studies: Technical Challenges & Solutions & Outcomes

  • Pierre Burguiere Director - Analytical Development & Nonclinical Research, GenSight Biologics

Synopsis

• LHON disease and Gensight GS010 gene therapy & clinical trials (overall design & safety of bioanalytical assays)
• Two examples of challenges faced regarding bioanalytical protocols being used: i) qPCR specificity for assessment of viral particles systemic biodissemination; ii) Impact of blood sampling and blood cells isolation on physiological state of PBMCs used for cellular immune response measurement
• Technical solutions developed to overcome the encountered challenges
• Brief overview of safety bioanalysis outcomes and conclusions

1:30 pm Lunch & Networking

2:30 pm Panel Discussion: Determining Best Practice for Assay Use When Measuring Immune Response

  • Genine Winslow Founder & Chief Executive Officer , Chameleon Biosciences

4:00 pm Immunogenicity of Novel AAV Vectors

  • David Favre Vice President Translational Medicine , Asklepios BioPharmaceutical

Synopsis

• Understanding adaptive and innate immunity to AAVs through preclinical models and clinical assessment strategies
• Developing inclusion and exclusion criteria and utilizing in-life monitoring
• What does pre-existing immunity mean for re-dosing and what are the safety considerations

4:30 pm Next Generation Design of Immune-Evading AAV Vectors

Synopsis

• AAV vectors and the challenge of immune responses
• Drivers of AAV immunogenicity
• Design of AAV vectors that evade immune responses

5:00 pm Scientific Poster Session

Synopsis
