AskBio Announces 11 Presentations at the American Society of Gene and Cell Therapy 26th Annual Meeting in 2023

Asklepios BioPharmaceutical, Inc. (AskBio), a gene therapy company wholly owned and independently operated as a subsidiary of Bayer AG, will deliver 11 presentations offering insights into the research and development of adeno-associated virus (AAV) therapies for a range of diseases at the American Society of Gene and Cell Therapy (ASGCT) 26^th Annual Meeting taking place May 16–20, 2023, in Los Angeles, USA.

AskBio presentations cover pre-clinical research into immune responses to AAV, data on methods to improve the efficacy of AAV-gene therapy and research into improved analytics and bioassays. A symposium on a platform approach to AAV manufacturing will also be presented by AskBio’s subsidiary Viralgen.  

"Our breadth of scientific presence at ASGCT reflects the type of cutting edge pre-clinical research our teams undertake, which we believe is essential for the development of successful gene therapies in the future," said Jude Samulski, Chief Scientific Officer and Co-Founder of AskBio. "We look forward to presenting updates on pioneering work that spans the subtlety of AAV vector design, quantifiable transgene expression and preclinical efficacy, with the aim of furthering AAV therapy for additional unmet clinical needs."

With an ambitious portfolio of gene therapies at various stages of research and development, AskBio continues to develop AAV-based therapies to treat some of the world’s most debilitating diseases, including congestive heart failure, Huntington’s disease, limb-girdle muscular dystrophy, multiple system atrophy, Parkinson’s disease, and Pompe disease. By targeting these therapy areas, AskBio aims to deliver breakthrough treatments that could benefit more than 35 million patients worldwide.^1–7

About Viralgen
Viralgen, an independently operated Contract Development and Manufacturing Organization (CDMO), was founded in 2017 as a joint venture between AskBio and Columbus Venture Partners (a venture capital firm based in Spain). As one of the world’s leading manufacturers of cGMP-certified AAV, Viralgen uses the Pro10^TM based suspension manufacturing platform, a technology licensed from AskBio and developed by CTO Josh Grieger and co-founder R. Jude Samulski, PhD, at University of North Carolina. It is believed that Pro10™ increases scalability, performance and precision of AAV therapies. Located in Spain, in the Gipuzkoa Science and Technology Park, Viralgen produces AAV gene therapy treatments for pharmaceutical and biotech companies with the aim of accelerating the delivery of new treatments that can improve patients’ lives.

The company’s clinical facilities have four cGMP manufacturing suites, with 250-liter and 500-liter bioreactors. In 2020, Viralgen expanded within the scientific park by constructing a new building for large-scale commercial manufacturing. The new state-of-the-art facility includes three additional cGMP suites with a manufacturing capacity of 2,000 liters each, as well as a suite dedicated to fully automated fill and finish operations. The new facility has received cGMP certification by the Spanish Agency for Medicines and Medical Devices (AEMPS) as part of the EMA network.
