RIBOMIC Announces First Injection in the Phase 2 Clinical Trial of RBM-007 (TOFU Study) in Subjects with Wet Age-Related Macular Degeneration

TOKYO--(BUSINESS WIRE)-- RIBOMIC, Inc., a clinical stage pharmaceutical company specializing in aptamer therapeutics and traded on the Mothers Market of the Tokyo Stock Exchange (Code Number: 4591), today announced that first patient has received injection in the phase 2 trial of RBM-007 for the treatment of exudative age-related macular degeneration (AMD) in the United States. The first site started enrollment at the end of December 2019 and five sites are now active across the United States.

About RBM-007 and development background

RBM-007 is a novel oligonucleotide-based aptamer with potent anti-FGF2 (fibroblast growth factor 2) activity. Currently approved therapies for wet AMD, intravitreal injections of anti-VEGF drugs, have shown dramatic visual benefits for wet AMD patients. However, a significant portion of wet AMD patients exhibit incomplete response to therapy, and over the extended management course can lose vision, with the formation of submacular fibrosis as one risk factor. RIBOMIC investigated a novel therapy for wet AMD targeting fibroblast growth factor 2 (FGF2), which is implicated in not only angiogenesis but also fibrosis in several diseases, and created RBM-007, a novel oligonucleotide-based aptamer with potent anti-FGF2 activity. RBM-007 is chemically synthesized, and pharmacokinetic studies of RBM-007 in the rabbit vitreous revealed high and relatively long-lasting profiles, which are superior to the other approved anti-VEGF drugs. The dual action of RBM-007 (anti-angiogenic and anti-scarring) holds promise as an additive or alternative therapy to anti-VEGF treatments for wet AMD.

About wet Age-related Macular Degeneration

Wet (exudative) age-related macular degeneration, is the leading cause of blindness in the United States and Europe. It is caused by the formation of abnormal and leaky new blood vessels under the retina, termed choroidal neovascularization. The leakage of fluid from the vessels causes retinal thickening and retinal degeneration including fibrotic scar formation, and leads to severe and rapid loss of vision.
