Condition(s) targeted: Open-angle Glaucoma; Ocular Hypertension

Intervention: Preservative-Free Tafluprost (Drug); Comparator: timolol (Drug)

Phase: Phase 3

Status: Completed

Sponsored by: Merck Sharp & Dohme Corp.

Official(s) and/or principal investigator(s):
Medical Monitor, Study Director, Affiliation: Merck Sharp & Dohme Corp.

Summary

This study was to compare the safety and efficacy of the preservative-free formulation of 0. 0015% MK2452 (tafluprost) and preservative-free 0. 5% timolol maleate in patients with open-angle glaucoma and ocular hypertension. This study was to demonstrate that the preservative-free formulation of 0. 0015% tafluprost is non-inferior to preservative-free 0. 5% timolol maleate.

Clinical Details

Official title: A Phase III, Randomized, Active Comparator-Controlled, Twelve-Week, Double-Masked Clinical Trial to Compare the Efficacy and Safety of Preservative-Free MK2452 (0.0015%) and Preservative-Free Timolol Maleate (0.5%) in Patients With Open-Angle Glaucoma and Ocular Hypertension
