RIBOMIC Announces Preliminary Topline Data From Phase 2 Trials of RBM-007 for Wet Age-Related Macular Degeneration

TOKYO–()–RIBOMIC, Inc., a clinical stage pharmaceutical company specializing in aptamer therapeutics (TOKYO:4591), today announced the topline data from the Phase 2 TOFU study of RBM-007 in patients with Wet Age-Related Macular Degeneration (wAMD).

TOFU study is a double-masked, randomized, active-controlled Phase 2 trial (n=86) evaluating the efficacy and safety of RBM-007 monotherapy and RBM-007 in combination with Eylea® compared to Eylea® monotherapy in patients with wAMD who are previously treated with Standard of Care (anti-VEGF drugs).

As a result of the analysis, RBM-007 monotherapy or RBM-007 in combination with Eylea® did not demonstrate vision improvement over Eylea® monotherapy in this patient population.

On the other hand, in treatment naïve wAMD patients, preliminary interim data from the ongoing phase 2 TEMPURA investigator sponsored trial evaluating the safety and efficacy of RBM-007 monotherapy are showing improvement in vision and retinal anatomy.

Additional analyses of secondary endpoints of TOFU are ongoing. The company is planning to share the detailed results together with those from its RAMEN extension study and TEMPURA study as full dataset.

About RBM-007

RBM-007 is a novel oligonucleotide-based aptamer with potent anti-FGF2 (fibroblast growth factor 2) activity. FGF2 is implicated in not only angiogenesis but also fibrosis in several diseases including wAMD. The dual action of RBM-007 (anti-angiogenic and anti-scarring) holds promise as an additive or alternative therapy to anti-VEGF treatments for wAMD. Three studies are currently ongoing for wAMD: 1. Active-controlled, double masked trial, TOFU study (NCT04200248); 2. Single-arm, open-label extension trial, RAMEN (NCT04640272); and 3. Investigator sponsored trial with treatment naïve wAMD patients, the TEMPURA study (NCT04895293).

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.
