Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Phase III study to compare the safety and efficacy of intraocular implants containing Travoprost at two different elution rates versus Timolol Maleate Ophthalmic Solution, 0.5% (Timolol) in reducing elevated intraocular pressure in subjects with open angle glaucoma (OAG) or ocular hypertension (OHT)

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a prospective, randomized, double-masked, active-controlled, parallel-group, multi-center trial comparing the efficacy and safety of the Model G2TR-063 Travoprost Intraocular Implant and the Model G2TR-125 Travoprost Intraocular Implant to topical Timolol in subjects with OAG or OHT. The staff who record key efficacy measures and the study subjects will remain masked to study treatment.
