REGENXBIO Closes $370M+ Gene Therapy Eye Care Collaboration Agreement with AbbVie for Wet AMD and Diabetic Retinopathy

ROCKVILLE, Md., November 9, 2021 — REGENXBIO Inc. (Nasdaq: RGNX) today announced the closing of its Collaboration and License Agreement with AbbVie to develop and commercialize RGX-314, a potential one-time gene therapy for the treatment of wet age-related macular degeneration (wet AMD), diabetic retinopathy (DR) and other chronic retinal diseases. As previously announced on September 13, 2021, under the terms of the agreement, REGENXBIO will receive an upfront payment from AbbVie of $370 million with the potential for REGENXBIO to receive up to $1.38 billion in additional development, regulatory and commercial milestones. 

Under the collaboration, REGENXBIO will be responsible for completion of the ongoing trials of RGX-314. AbbVie and REGENXBIO will collaborate and share costs on additional trials of RGX-314, including the planned second pivotal trial evaluating subretinal delivery for the treatment of wet AMD and future trials. AbbVie will lead the clinical development and commercialization of RGX-314 globally. REGENXBIO will participate in U.S. commercialization efforts as provided under a mutually agreed upon commercialization plan. 

REGENXBIO and AbbVie will share equally in profits from net sales of RGX-314 in the U.S. and AbbVie will pay REGENXBIO tiered royalties on net sales of RGX-314 outside the U.S. In addition, REGENXBIO will lead the manufacturing of RGX-314 for clinical development and U.S. commercial supply, and AbbVie will lead manufacturing of RGX-314 for commercial supply outside the U.S.

About RGX-314

RGX-314 is being investigated as a potential one-time treatment for wet AMD, diabetic retinopathy, and other chronic retinal conditions. RGX-314 consists of the NAV AAV8 vector, which encodes an antibody fragment designed to inhibit vascular endothelial growth factor (VEGF). RGX-314 is believed to inhibit the VEGF pathway by which new, leaky blood vessels grow and contribute to the accumulation of fluid in the retina.

REGENXBIO is advancing research in two separate routes of administration of RGX-314 to the eye, through a standardized subretinal delivery procedure as well as delivery to the suprachoroidal space. REGENXBIO has licensed certain exclusive rights to the SCS Microinjector® from Clearside Biomedical, Inc. to deliver gene therapy treatments to the suprachoroidal space of the eye.
