NCT03868124

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)

Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in Diurnal IOP (as Measured at 8AM and 10AM) Through 3 Months Postoperative

    Change from time-matched baseline in IOP at 8AM and 10AM at Day 10, Week 6 and Month 3. Day 10 8AM IOP minus Baseline 8AM IOP; Day 10 10AM IOP minus Baseline 10AM IOP; Week 6 8AM IOP minus Baseline 8AM IOP; Week 6 10AM IOP minus Baseline 10AM IOP; Month 3 8AM IOP minus Baseline 8AM IOP; Month 3 10AM IOP minus Baseline 10AM IOP.

    3 Months

Secondary Outcomes (1)

  • Mean IOP (Control Group vs. Each Implant Group) Through 12 Months Postoperative

    12 Months
