"At ASGCT (Free ASGCT Whitepaper), the data we present will highlight the potential of our proprietary AAV capsids and gene constructs to express recombinant protein in target eye tissues and rescue mutant phenotypes," said Brian Kevany, Ph.D., Chief Technical Officer and Head of Research at Abeona. "We have started to submit pre-IND meeting requests to the FDA for our gene therapy product candidates and anticipate meetings to take place in the second quarter of 2023. We are excited for the opportunity to share our new data with the scientific community at ASGCT (Free ASGCT Whitepaper)."
