Clinical Study Comparing Two Models of a Travoprost Intraocular Implant

Phase 3

Completed

• Conditions: Glaucoma, Open-Angle; Ocular Hypertension
• Interventions: Combination Product: G2-TR intraocular implant containing travoprost; Drug: Sham surgery + active-comparator eye drops

• Registration Number: NCT03868124
• Lead Sponsor: Glaukos Corporation

Brief Summary

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

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.

Secondary Outcome Measures

Name	Time	Method
Mean IOP (Control Group vs. Each Implant Group) Through 12 Months Postoperative	12 Months	Difference in mean IOP, between each test group and the control group, for IOP measurements through the Month 12 follow-up visit
