| E.3 | Principal inclusion criteria | 
| * Male and female subjects, at least 21 years of age, inclusive. * Diagnosis of ocular hypertension or primary open angle glaucoma in at least one eye.
 * Subject with intraocular hypertension must have an IOP ≥ 22 mm Hg at the 8:00 AM (± 1 h) and ≥ 18 mm Hg in the afternoon measurement in at least one eye and ≤ 32 mm Hg at all time points in both eyes, at screening and on Day -7.
 * Subject with diagnosed glaucoma must have an IOP ≥ 18 mm at screening and ≥ 22 mm Hg on Day -7, at the 8:00 AM and the afternoon  measurement in at least one eye.
 * Best corrected visual acuity score of 6/30 (20/100 Snellen, 0.7 LogMar) or better in each eye as  measured by ETDRS visual acuity test at screening.
 * Central corneal pachymetry measurement 420 to 620 μ in qualifying eye at screening.
 * Cup-to-disk ratio ≤ 0.8.
 
 |  | 
| E.4 | Principal exclusion criteria | 
| * Presence of extreme narrow angle with complete or partial closure, as measured by gonioscopy or at risk for angle closure. * History or signs of penetrating ocular trauma in either eye less than 6 months prior to randomization or intraocular laser procedures less than 3 months prior to randomization.
 * Risk of visual field or visual acuity worsening in either eye as a consequence of glaucoma progression or consequence of participation in the trial or any other ocular disease.
 * History of any ocular filtering surgical intervention OR previous glaucoma intraocular surgery in study eye(s).
 * Any other intraocular surgery within 6 months of screening.
 * Progressive retinal or optic nerve disease from any cause other than glaucoma.
