REGENXBIO to Launch New Manufacturing Facility for NAV Technology-based AAV Gene Therapies

Internal manufacturing facility expected to support future clinical and commercial production

Facility will use novel platform suspension cell culture process, which can produce scalable, highly purified NAV Technology-based vectors

ROCKVILLE, Md., May 15, 2019 /PRNewswire/ -- REGENXBIO Inc. (RGNX), a leading clinical-stage biotechnology company seeking to improve lives through the curative potential of gene therapy based on its proprietary NAV® Technology Platform, today announced its plan to construct a current good manufacturing practice (cGMP) production facility, to be located in Rockville, Maryland. The new cGMP production facility will be integrated into REGENXBIO's previously announced new 132,000 square foot headquarters, for which construction is currently underway, and will allow for production of NAV Technology-based vectors at scales up to 2,000 liters using REGENXBIO's platform suspension cell culture process.  The facility will be designed to meet global regulatory requirements and is expected to be operational in 2021. The cGMP production facility will complement the company's current external manufacturing capabilities, enabling a reliable supply of NAV vectors from both internal and external sources. The construction of the facility is not expected to have any effect on REGENXBIO's previously issued financial guidance relating to its cash, cash equivalents and marketable securities as of December 31, 2019.

"REGENXBIO's own cGMP production facility is designed to enable us to reach manufacturing scales suitable for future commercial production," said Curran Simpson, Senior Vice President of Product Development and Chief Technology Officer at REGENXBIO. "The creation of this additional manufacturing capacity using our platform suspension cell culture process will allow us to more efficiently advance our development programs from research stage to the clinic and ultimately to patients, while ensuring manufacturing capacity availability. We expect our manufacturing network to be capable of supporting our internal programs through clinical development and potential commercialization."

"The manufacturing facility design will enable concurrent production of multiple gene-therapy vectors, and the facility will be co-located with our process development and analytical teams.  This integrated approach will allow for more efficient development, manufacture and release of vectors for new indications," said Kenneth T. Mills, President and Chief Executive Officer of REGENXBIO.  "The new facility will also provide us with scheduling flexibility, allowing for reduced product development timelines at sufficient capacity to meet clinical and projected commercial requirements."
