The Avalanche Approach

Currently, wet age-related macular degeneration is treated with frequent injections of anti-VEGF protein directly into the eyeball. This creates a burden for both patients and physicians, and limits access for those who are not able to comply with frequent visits and injections.

The results of a Phase 1, 52-week trial of Avalanche Biotechnologies’ rAAV.sFLT-1 (AVA-101) gene therapy for the treatment of wet age-related macular degeneration (wAMD) have been published online by The Lancet. The study sought to evaluate the safety of rAAV.sFLT-1 via a single subretinal injection. Results of the study demonstrate that rAAV.sFLT-1 was safe and well tolerated, and support ocular gene therapy as a potential long-term treatment option for wAMD.

“The use of gene therapy to reprogramme genetically normal cells of the retina to take on additional functions opens a new chapter in potential AAV applications.”
