Gene Therapy VG801 Targets Stargardt Disease, Gains FDA Priority for Vision-Restoring Trials
  • VG801 is an innovative gene therapy designed to deliver a full-length, functional ABCA4 gene to address the genetic root cause of Stargardt disease, which affects approximately 1 in 8,000 to 10,000 people worldwide and currently has no approved treatments.

  • Stargardt disease is the most common inherited retinal disorder, characterized by progressive central vision loss starting in childhood or adolescence, and affects about 1 in 8,000 to 10,000 individuals globally.

  • VG801 utilizes VeonGen’s proprietary vgRNA REVeRT platform and engineered vgAAV capsids to target all forms of Stargardt disease by restoring ABCA4 gene function in photoreceptor cells.

  • Currently in Phase I/II clinical trials, VG801 has patient dosing underway and aims to restore vision by targeting the underlying genetic mutation.

  • VeonGen has received FDA's Regenerative Medicine Advanced Therapy (RMAT) designation for VG801, which accelerates development through enhanced FDA engagement, streamlined processes, and potential priority review.

  • VG801 has also earned designations such as Rare Pediatric Disease and Orphan Drug status, and VeonGen is collaborating with the FDA under the Rare Disease Endpoint Advancement pilot program.

  • VeonGen’s broader pipeline includes therapies for retinitis pigmentosa and applications in cardiovascular and CNS diseases, leveraging proprietary gene therapy platforms.

  • Based in Munich, Germany, VeonGen focuses on next-generation gene therapies for high unmet medical needs, with additional candidates like VG901 for retinitis pigmentosa.

  • The therapy aims to restore ABCA4 expression in photoreceptor cells to treat all forms of ABCA4-mutated Stargardt disease, the most common inherited retinal disorder causing progressive vision loss.
