Eligibility
Inclusion criteria
* Unilateral or bilateral primary open angle glaucoma, capsular glaucoma, pigmentary glaucoma or ocular hypertension. * Patients currently on IOP reducing therapy: IOP greater than or equal to 25mmHg (Ltwo IOP determinations at pre-study separated by at least one hour) OR Patients without IOP reducing therapy: IOP greater than or equal to 30mmHg (two IOP determinations at pre-study separated by at least one hour).
Exclusion criteria
* History of acute angle closure or closed/barely open anterior chamber angle. * Current use of contact lenses. * Ocular surgery or argon laser trabeculoplasty (ALT) within three months prior to pre-study visit. * Ocular inflammation/infection occurring within three months prior to pre-study visit. * Hypersensitivity to benzalkonium chloride or to any other component of the study drug solutions. * Other abnormal ocular condition or symptom preventing the patient from entering the study, according to the investigator's judgement. * Patients with conditions in which treatment with B-blocking agents are contraindicated: cardiac failure, sinus bradycardia, second and third degree atrio-ventricular block. * Patients with conditions in which treatment with B-blocking agents are contraindicated: bronchial asthma, history of bronchial asthma or chronic obstructive pulmonary disease. * Inability to adhere to treatment/visit plan. * Have participated in any other clinical study within one month prior to pre-study visit.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The differences from baseline in diurnal IOP reduction after six months of treatment will be tested between the fixed combination and the monotherapy groups. | 6 months |
| Primary objective: to demonstrate that the fixed combination of latanoprost and timolol has a better IOP-reducing effect than the individual monotherapies. | 6 months |
Secondary
| Measure | Time frame |
|---|---|
| To compared the number of treatment failures and patients withdrawn due to uncontrolled IOP from baseline to Week 26 between treatment groups | 6 months |
| To describe the IOP development from baseline to Week 26 for all treatment groups | 6 months |
| To examine, within treatment groups, the diurnal IOP reducing effect from baseline for all effect from baseline between the monotherapies latanoprost and timolol | 6 months |
| To examine, within the fixed combination treatment group, the diurnal IOP reducing effect from baseline to Week 26 and Week 52 | 6 months |
| To follow the safety variables throughout the study periods. | 6 months |
| To compared the IOP reducing effect from baseline to Week 26 of the monotherapies with the IOP reducing effect from Week 26 to Week 52 of the fixed combination | 6 months |
| To compare the diurnal IOP reducing effect from baseline between the monotherapies latanoprost and timolol at Week 26 | 6 months |
