– AbbVie and REGENXBIO form a strategic partnership combining eye care and gene therapy expertise

– Companies will develop and commercialize RGX-314, an investigational gene therapy for wet age-related macular degeneration, diabetic retinopathy and other chronic retinal diseases

– REGENXBIO to receive $370 million upfront payment

NORTH CHICAGO, IL and ROCKVILLE, MD, USA I September 13, 2021 I AbbVie (NYSE: ABBV) and REGENXBIO Inc. (Nasdaq: RGNX) today announced a partnership 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. RGX-314 is currently being evaluated in patients with wet AMD in a pivotal trial utilizing subretinal delivery, and in patients with wet AMD and DR in two separate Phase II clinical trials utilizing in-office suprachoroidal delivery. 

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 shall participate in U.S. commercialization efforts as provided under a mutually agreed upon commercialization plan.

“We are committed to finding solutions for patients living with difficult-to-treat retinal diseases and to helping preserve and protect our patients from visual impairment and devastating vision loss,” said Tom Hudson, MD, senior vice president, R&D, chief scientific officer, AbbVie. “In collaboration with REGENXBIO, we aim to make a remarkable impact for the millions of patients suffering from vision loss associated with retinal diseases.”

“AbbVie is a strong, complementary partner for REGENXBIO. We expect to leverage AbbVie’s global developmental and commercial infrastructure within eye care with our expertise in AAV gene therapy clinical development and deep in-house knowledge of manufacturing and production to continue the development of RGX-314,” said Kenneth T. Mills, president and chief executive officer of REGENXBIO.

Under the terms of the agreement, AbbVie will pay REGENXBIO a $370 million upfront payment with the potential for REGENXBIO to receive up to $1.38 billion in additional development, regulatory and commercial milestones. REGENXBIO and AbbVie will share equally in profits from net sales of RGX-314 in the U.S. 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.  

The transaction is expected to close by the end of 2021, subject to the satisfaction of customary closing conditions, including applicable regulatory approvals.

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 retina1.

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.

About Wet AMD
Wet AMD is characterized by loss of vision due to new, leaky blood vessel formation in the retina2. Wet AMD is a significant cause of vision loss in the United States, Europe and Japan, with up to 2 million people living with wet AMD in these geographies alone3. Current anti-VEGF therapies have significantly changed the landscape for treatment of wet AMD, becoming the standard of care due to their ability to prevent progression of vision loss in the majority of patients4. These therapies, however, require life-long repeated intraocular injections, to maintain efficacy5,6.  Due to the burden of treatment, patients often experience a decline in vision with reduced frequency of treatment over time7.

About Diabetic Retinopathy
Diabetic retinopathy (DR) is the leading cause of vision loss in adults between 24 and 75 years of age worldwide8. DR affects approximately eight million people in the United States alone9. The spectrum of DR severity ranges from non-proliferative diabetic retinopathy (NPDR) to proliferative diabetic retinopathy (PDR) and as DR progresses, a large proportion of patients develop vision threatening complications, including diabetic macular edema (DME) and neovascularization that can lead to blindness10.  Current treatment options for patients with DR include “watchful waiting”, anti-VEGF treatment, retinal laser or surgical treatment8.
