Safety and Tolerability of a Timolol Releasing Intraocular Implant in Subjects With Primary Open-angle Glaucoma

Timolol will be delivered through an investigational drug called 'TimoD implant'. This implant is placed inside one eye, the study eye, with the help of an instrument (investigational device) called an injector system. Three dose ranges of TimoD implant will be tested (low, intermediate, and high) in 3 groups of 6 participants. The Timolol will be released slowly through the implant for up to 1 year (main phase). Approximately 1 year after the TimoD implant is placed into the eye and in absence of contraindications, the participants will be invited to continue the study in an extension phase. If the participants agree to enter the extension phase and the study investigator confirms it is safe for them, the TimoD implant will remain in the study eye for one additional year.
