Adverum is advancing a robust pipeline of gene therapy product candidates targeting unmet medical needs in ophthalmology and rare diseases.
- Product Candidate, Indication
For wet AMD, we are advancing our preclinical gene therapy product candidate ADVM-022 (AAV.7m8-aflibercept). With a proprietary vector capsid (AAV.7m8) and a proprietary expression cassette, ADMV-022 is administered as a single intravitreal injection and is designed to minimize the treatment burden of frequent injections. In preclinical studies, a single intravitreal injection of ADVM-022 showed efficacy that was comparable to the anti-VEGF standard of care.

- AVA-311 (Ocular Disease)¹
AVA-311 is being developed for the treatment of Juvenile X-linked Retinoschisis (XLRS), an inherited retinal disease caused by mutations in the RS1 gene located on the X chromosome, therefore occurring almost exclusively in males. AVA-311 is comprised of an optimized AAV vector to deliver the RS1 gene into the eye via intravitreal injection.
In May 2014, Adverum signed a collaboration agreement with Regeneron that includes the development of AVA-311.
¹ Collaboration agreement with Regeneron Pharmaceuticals to research, develop, and commercialize gene therapy products (AVA-311 and up to 3 undisclosed targets) for ophthalmic diseases
² Collaboration agreement with Editas Medicines to explore the delivery of genome editing medicines for the treatment of inherited retinal diseases
Through directed evolution, we generate a diverse library of millions of AAV variants and subsequently screen the variants in multiple in vitro and in vivo tests to identify the optimal variant for a specific disease. Our directed evolution technology allows us to create proprietary vectors and optimize them to target cells in tissues such as different layers of the retina. Each of these cell layers constitutes a potential therapeutic target for currently unmet medical needs, providing us with multiple opportunities to apply our directed evolution technology.
Our seasoned pharmaceutical development team has decades of gene therapy manufacturing experience. Adverum’s industrialized manufacturing process—based on our proprietary baculovirus expression system—is highly efficient and scalable, with production yields up to one hundred times greater than those obtained using conventional AAV production systems.
Our process enables us to manufacture commercial grade material for diseases with large patient populations. We have performed multiple single use bioreactor production / purification runs and have the ability to make highly concentrated purified vector.
Adverum collaborates with leading biopharmaceutical companies and academic institutions to advance the potential of gene therapy for treating patients.
Our collaboration agreements with Editas leverage our AAV expertise and technologies in ophthalmic vector development and product delivery. With Editas, we are providing our AAV vectors for use with Editas’ CRISPR-based genome editing technologies to treat inherited retinal diseases. Our agreement with Regeneron provides for the development of up to eight distinct ocular therapeutic targets, four of which are already identified, including AVA-311 for the treatment of juvenile XLRS.
Our current collaborators include:
We are open to exploring additional collaboration opportunities and encourage you to contact us for more information.
