Five abstracts accepted with new research and technology insights and data to further enhance AAV-based gene therapy candidates

LONDON, May 02, 2022 (GLOBE NEWSWIRE) -- Freeline Therapeutics Holdings plc (Nasdaq: FRLN) (the “Company” or “Freeline”) today announced the upcoming presentation of five posters at the 25th Annual Meeting of the American Society of Gene and Cell Therapy (ASGCT) that will take place May 16-19, 2022 in Washington, D.C.

The presentations will provide new insights and data regarding key elements to further enhance the efficacy, safety, sustainability and predictability of adeno-associated virus (AAV)-based gene therapy candidates to treat and potentially cure debilitating genetic disorders, including the following:

  • the development of novel AAV capsid variants with enhanced transduction of liver cells and reduced immunogenicity;
  • the improved assessment of host-cell derived DNA impurities encapsidated during AAV manufacturing;
  • the development of standardized, high-throughput testing of patients for anti-AAV antibodies; and
  • approaches to further improve and accelerate AAV vector manufacturing to commercial scale.

The abstracts of the five poster presentations were published on the ASGCT website today:

Engineering AAV Capsid Variants to Overcome Pre-existing Immunity and Improve Gene Delivery to Human Liver – Feiner R. et al.

Host Cell DNA Impurity Sizing in rAAV by an 18S rRNA Gene-based ddPCR Approach – Thoennissen F. et al.

Development of a High-throughput, Miniaturized, Semi-automated Rapid Transduction Inhibition Assay (TIA) for the Characterization of Anti-AAV Antibodies in Gene Therapy – Ravi S. et al.

Investigating the Oxygen Control Before and After Fixed Bed in the iCELLis® Nano Bioreactor to Create a More Robust Scale-Down Model for the iCELLis® 500 Bioprocess – Boscher M. et al.

Lysis and Clarification Strategies for AAV Suspension Processes – Weiss C. et al.

The poster presentations will be available on the Investors section of Freeline’s website following presentation at the ASGCT annual meeting.
