Othera Pharmaceuticals developed OT-551 as an antioxidant and anti-inflammatory agent. OT-551 downregulates the overexpression of the protein complex nuclear factor (NF)-kappa B. It is known that NF-kappa B is highly activated when oxidative stress, inflammation, and angiogenesis occurs. OT-551 was studied in phase II clinical trial for the treatment of age-related macular degeneration. In addition, the drug was studied for the treatment of cataracts and dry eyes; however, these studies were discontinued. Besides, phase II clinical trial for the treatment of geographic atrophy has shown that OT-551 might have limited or no benefit as a treatment for this disease.
