Visgenx and Charles River Announce Expansion of Gene Therapy Manufacturing Alliance


Charles River will manufacture for Visgenx's investigational gene therapy treatment for dry Age-Related Macular Degeneration

SAN DIEGO, Dec. 7, 2023 /PRNewswire/ -- Visgenx, Inc., a biotechnology company focused on developing gene therapies for degenerative retinal diseases, announced an extension of their contract development and manufacturing organization (CDMO) collaboration with Charles River Laboratories International, Inc., for VGX-0111, a gene therapy being developed by Visgenx for dry age-related macular degeneration (AMD).

We have the utmost confidence in Charles River to manufacture for VGX-0111

"Manufacturing of gene therapies is highly complex and product quality is of paramount importance," said William Pedranti, CEO, Visgenx. "We have the utmost confidence in Charles River to manufacture for VGX-0111 as we work toward our goal to bring treatment for those suffering from dry-AMD."

Following Visgenx's Type B pre-IND meeting with the FDA in the summer of 2023, Charles River will begin manufacturing materials for VGX-0111 with the goal of initiating a clinical proof-of-concept in 2025. The material manufactured by Charles River will support a good laboratory practice (GLP) pre-clinical toxicology study and follows a prior adeno-associated virus (AAV) production collaboration. 

"We are excited to expand our partnership with Visgenx on this gene therapy," said Kerstin Dolph, Corporate Senior Vice President, Biologics Solutions, Charles River. "The collaboration will tap into our premier gene therapy CDMO capabilities, and we are thrilled that our expertise will help to bring VGX-0111 one step closer to the clinic."

What is Dry-AMD?
Dry-AMD is a progressive eye disease that affects over 11 million people in the United States and is the leading cause of severe vision loss or blindness in adults over age 50. There is no known cure for dry-AMD and only limited treatments are available.

Dysregulation of very long-chain fatty acid biosynthesis resulting from declining expression of a gene known as ELOVL2 is believed to be a contributor to dry-AMD. Numerous studies have elucidated the importance of ELOVL2 in maintaining the function and promoting survival of retinal cells and other tissues. The downregulation of ELOVL2 may lead to accelerated cellular aging and potentially form the foundational basis of dry-AMD.

Visgenx's lead product, VGX-0111, a candidate gene therapy based on the ELOVL2 gene, is intended to restore a physiologically healthy level of ELOVL2 expression, thereby potentially slowing or halting vision loss resulting from dry-AMD.
