Phase 4

Completed

• Conditions: Glaucoma
• Interventions: Drug: Brinzolamide/Timolol Maleate Fixed Combination (AZARGA); Drug: Dorzolamide/timolol Maleate Fixed Combination (COSOPT)

• Registration Number: NCT01471158
• Lead Sponsor: Alcon Research

Brief Summary

The purpose of this study is to assess patient preference of AZARGA® compared to COSOPT® after a single drop of each medication is administered to both eyes, in patients with open-angled glaucoma or ocular hypertension.

• On a stable regimen intraocular pressure (IOP) lowering medication within 30 days of screening visit.
• IOP considered to be safe (in the opinion of the investigator) in both eyes in such a way that should assure clinical stability of vision and the optic nerve throughout the study period.

• Corneal dystrophies in either eye.
• Risk of visual field or visual acuity worsening as a consequence of participating in this study, in the investigator's best judgment.
• Bronchial asthma or a history of bronchial asthma, or severe chronic obstructive pulmonary disease that would preclude the safe administration of a topical beta-blocker.

Arm && Interventions

Group	Intervention	Description
Azarga/Cosopt	Dorzolamide/timolol Maleate Fixed Combination (COSOPT)	Following administration of the baseline dose (each intervention instilled in one eye in a contralateral fashion to establish baseline ocular comfort for each medication), Azarga will be instilled one drop in each eye on Day One, after which Cosopt will be administered one drop in each eye on Day Two.
Azarga/Cosopt	Brinzolamide/Timolol Maleate Fixed Combination (AZARGA)	Following administration of the baseline dose (each intervention instilled in one eye in a contralateral fashion to establish baseline ocular comfort for each medication), Azarga will be instilled one drop in each eye on Day One, after which Cosopt will be administered one drop in each eye on Day Two.
Cosopt/Azarga	Brinzolamide/Timolol Maleate Fixed Combination (AZARGA)	Following administration of the baseline dose (each intervention instilled in one eye in a contralateral fashion to establish baseline ocular comfort for each medication), Cosopt will be administered one drop in each eye on Day One, after which Azarga will be administered one drop in each eye on Day Two.
Cosopt/Azarga	Dorzolamide/timolol Maleate Fixed Combination (COSOPT)	Following administration of the baseline dose (each intervention instilled in one eye in a contralateral fashion to establish baseline ocular comfort for each medication), Cosopt will be administered one drop in each eye on Day One, after which Azarga will be administered one drop in each eye on Day Two.

Primary Outcome Measures

Name	Time	Method
Discomfort	One minute after instillation	One drop of medication will be instilled in each eye. At one minute after instillation, subject will be given an Ocular Discomfort Scale and will record ocular discomfort on a questionnaire using a 10-point scale, with 0 being no discomfort and 09 being substantial discomfort.
