Phase 2 study initiated for oral anti-VEGF, anti-PDGF inhibitor

MIAMI — An oral tyrosine kinase inhibitor under study for use in treating wet age-related macular degeneration has moved forward into a phase 2 trial, a speaker said.Reporting positive phase 1 study results for X-82 (Xcovery Vision), an inhibitor of both anti-VEGF and anti-PDGF activity, Jason S. Slakter, MD, said at Angiogenesis, Exudation, and Degeneration 2015, “[X-82] has low toxicity in oral administration. Phase 1 study has shown some anatomic benefit, and a phase 2 program is kicking off.”

Phase 3 studies of lampalizumab for geographic atrophy enrolling

MIAMI — Phase 3 studies of lampalizumab are underway based on results of the phase 2 MAHALO study, which showed evidence that treatment slows the rate of geographic atrophy progression in patients with age-related macular degeneration, a speaker told colleagues.“Certainly there is a significant unmet medical need with regard to geographic atrophy,” Carl D. Regillo, MD, said at Angiogenesis, Exudation, and Degeneration 2015. “There’s more than 5 million people worldwide affected by GA, and there’s no effective treatment.”

AMD patients with low luminance vision garner twice the benefit of Lucentis treatment

MIAMI — Vision in dim light improves twice as much as vision in normal light with Lucentis therapy in patients with age-related macular degeneration, Ronald E. Frenkel, MD, FACS, told colleagues at Angiogenesis, Exudation, and Degeneration 2015.“The gap between normal and dim vision at baseline may predict the patient’s response to treatment,” Frenkel said. “A smaller gap may be a manifestation of more mild retinal disease, and a wider gap portends poor vision gains.”
