Exton, PA-Othera Pharmaceuticals Inc. has announced the initiation of a phase II clinical trial by the National Eye Institute (NEI) of Othera's topical eye drop OT-551 in patients with geographic atrophy (GA). The NEI will investigate OT-551's potential to slow enlargement of the atrophic area in the macula and prevent progression to the vision-threatening advanced stages of age-related macular degeneration (AMD).
This phase II study will enroll 10 patients with bilateral GA who will receive three daily doses of OT-551 eye drop over 2 years. The primary efficacy measure will be percent change in area of GA in each eye, as measured by fundus photo grading. Secondary measures will include: progression to advanced neovascular or wet AMD, progression of GA area based on autofluorescence, changes in contrast sensitivity, drusen area, and best-corrected visual acuity, and number of eyes developing advanced AMD.
Additional outcomes will also be measured regarding lens opacity as part of an ongoing collaboration between Othera and the NEI on preventing or slowing the progression of cataract formation.
