One of humankind’s greatest fears is permanent vision loss.1 That’s why we are fearless in the fight against vision loss and committed to moving the field forward.

We are leading the way in complement science and believe that targeting complement C3 has the potential to address challenging retinal diseases. Using this approach, we are advancing the first potential therapy for geographic atrophy (GA), a leading cause of blindness worldwide.
