Agreement with Healthcare Royalty enables REGENXBIO to advance its broad gene therapy pipeline,

including pivotal program for RGX-314

ROCKVILLE, Md., Dec. 22, 2020 /PRNewswire/ — REGENXBIO Inc. (Nasdaq: 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 that it has entered into an agreement to sell a portion of the royalty rights due to REGENXBIO from Novartis Gene Therapies from the net sales of Zolgensma® to entities managed by Healthcare Royalty Management, LLC (HCR) for a gross purchase price of $200 million. This transaction provides immediate, non-dilutive capital to REGENXBIO for continued innovation in the development of potential breakthrough gene therapies for patients and completion of its internal manufacturing capabilities.

“Our rapidly advancing internal pipeline has enabled us to broaden the potential impact that gene therapies can have for patients in both large and orphan indications. This agreement with HCR provides us with significant additional non-dilutive funding to continue our momentum in the clinic focused on RGX-314 and our rare neurodegenerative disease platform, including RGX-121, as well as the opportunity to develop new innovations for patients in other disease areas," said Kenneth T. Mills, President and Chief Executive Officer of REGENXBIO. “The capital will continue to support our pipeline transition into late-stage development and the establishment of internal manufacturing facilities with 2,000 liter scale using our platform suspension cell culture process for emerging commercial requirements, so that we can continue to work towards our mission of improving the lives of patients."

Under the terms of the agreement, REGENXBIO will receive $200 million from HCR as an upfront payment in exchange for REGENXBIO’s royalty rights from the net sales of Zolgensma, including a portion of the royalties received in the fourth quarter of 2020, up to 1.3 times the purchase price until November 7, 2024 or, if such cap is not met by November 7, 2024, up to 1.5 times the purchase price thereafter. If either cap is met, the royalty rights would revert to REGENXBIO.

Zolgensma is currently approved for the treatment of Spinal Muscular Atrophy (SMA) in the United States, Japan, Europe, Brazil and Canada. Novartis is also pursuing registration in additional countries.

“Zolgensma is a truly innovative treatment for SMA based on REGENXBIO’s NAV technology which we believe demonstrates the transformational impact that gene therapy can offer patients. We are pleased to partner with REGENXBIO in this royalty agreement to recognize the value of this therapy, and to enable the further development of their internal pipeline of new gene therapies for patients in need," said Clarke B. Futch, Managing Partner & Chairman of HCR.

Morgan Stanley & Co. LLC served as sole structuring agent and Covington & Burling LLP served as counsel to REGENXBIO. Morgan Lewis & Bockius LLP acted as counsel to HCR.
