Summary

Glaucoma is the second most common cause of blindness in the world, second only to cataracts. The purpose of this study is to assess adverse events (AEs) and changes in disease activity in participants with open-angle glaucoma (OAG) receiving the XEN45 Glaucoma Treatment System (XEN45). XEN45 is an approved device for the treatment of OAG in participants in China who have not achieved satisfactory effectiveness with or are not suitable for intraocular pressure (IOP)-lowering medication, laser surgery, or are not tolerant of traditional filtration surgery. Adult participants with a diagnosis of OAG will be randomized to receive either XEN 45 or trabeculectomy. Around 130 participants will be enrolled in the study at approximately 15 sites in China. Participants will receive XEN45 implanted using the ab interno approach or trabeculectomy on Day 1 and will be followed for 60 months An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment.
