Outcomes
Primary Outcome Measures
Intraocular Pressures (IOPs) at Baseline
IOPs at baseline: mean IOP values at four timepoints (worse eye)
Intraocular Pressures (IOPs) at Week 1
IOPs at week 1: mean IOP values at four timepoints (worse eye)
Intraocular Pressures (IOPs) at Week 4
IOPs at week 4: mean IOP values at four timepoints (worse eye)
Primary Pharmacodynamic Variable Intention to Treat Efficacy Dataset: Change From Baseline in the Overall Diurnal Intraocular Pressure (IOP) at Week 4 (Worse Eye)
Overall treatment difference at 4 weeks (unpreserved-preserved) evaluated using a repeated measurements analysis of covariance (RM ANCOVA) model.
Primary Pharmacodynamic Variable Per Protocol Efficacy Dataset: Change From Baseline in the Overall Diurnal Intraocular Pressure (IOP) at Week 4 (Worse Eye)
Overall treatment difference at 4 weeks (unpreserved-preserved) evaluated using a repeated measurments analysis of covariance (RM ANCOVA) model.
Secondary Outcome Measures
Overall and Time-wise Comparisons of IOP at Week 1
The overall and time-wise, i.e. at 8:00, 12:00, 16:00 and 20:00, comparisons of IOP at week 1 (diurnal IOP and IOP value at given timepoint at 1 week minus corresponding value at baseline: unpreserved-preserved) were done using the RM ANCOVA model.
Change From Baseline in Time-wise IOPs at Week 4
The time-wise, i.e. at 8:00, 12:00, 16:00 and 20:00, comparisons of IOP at week 4 (IOP value at given timepoint at 4 weeks minus corresponding value at baseline: unpreserved-preserved) were done using the RM ANCOVA model.

5. Study Description
Brief Summary
The objective of this study is to investigate the pharmacodynamics (as expressed in intraocular pressure [IOP]) of two formulations of tafluprost 0.0015% eyedrops (preserved and unpreserved) in patients with open-angle glaucoma or ocular hypertension.
The primary aim of this study is to show that IOP reduction between the two formulations is equivalent at the end of the 4 week treatment period.
