Vesigen to Present New Preclinical Data on Ophthalmology Applications of Engineered ARMMs at 2024 ARVO Annual Meeting

CAMBRIDGE, Mass., May 1, 2024 /Business Wire/ — Vesigen Therapeutics, Inc., a biotechnology company developing a novel non-viral delivery platform for gene editors, RNA, and protein-based therapeutics, today announced that the Company will be presenting two posters sharing new preclinical data from its engineered ARMMs platform at the upcoming Association for Research in Vision and Ophthalmology (ARVO) Annual Meeting. The meeting will be held in Seattle, Washington from May 5-9.

Vesigen’s technology comprises engineered forms of a class of naturally existing vesicles to enable efficient functional delivery of complex intracellular payloads, while overcoming challenges observed with other modalities such as tissue specificity, toxicity, and re-dosability.

Vesigen will present preclinical data demonstrating successful biodistribution of its engineered ARMMs to non-human primate (NHP) photoreceptors and retinal pigment epithelium. The Company will also share new preclinical NHP data demonstrating functional delivery of genome editors to the retina and supporting therapeutic use of ARMMs in ocular diseases.

Details of the poster presentations are listed below. For more information about the ARVO Annual Meeting, including registration details, please visit
