Information source: Pfizer
ClinicalTrials.gov processed this data on August 23, 2015 Link to the current ClinicalTrials.gov record.
Condition(s) targeted: Glaucoma; Open Angle Glaucoma; Ocular Hypertension
Intervention: PhXA41 (Drug); timolol (Drug)
Phase: Phase 3
Status: Completed
Sponsored by: Pfizer Official(s) and/or principal investigator(s): Pfizer CT.gov Call Center, Study Director, Affiliation: Pfizer
Summary
PhXA41 is not inferior to timolol
Clinical Details
Official title: A 6-month, Randomized, Double-masked Comparison of Latanoprost (PhXA41) With Timolol in Patients With Open Angle Glaucoma or Ocular Hypertension. A Multi-centre Study in the United States.
Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator), Primary Purpose: Treatment
Primary outcome: to demonstrate the IOP-reducing effect of PhXA41 is comparable to that of timolol at the end of 6 months of treatment.
Secondary outcome: to describe the IOP development throughout the study period and to follow the safety variables in the two treatment groups.
Eligibility
Minimum age: 40 Years.
Maximum age: N/A.
Gender(s): Both.
Criteria:
Inclusion Criteria:
- Unilateral or bilateral primary open angle glaucoma, capsular glaucoma, pigmentary
glaucoma or ocular hypertension.
- Open angle glaucoma appearing more than 6 months after cataract surgery is recognized
as primary open angle glaucoma. (individuals requiring treatment bilaterally must
fulfill eligibility criteria for both eyes.)
- IOP of 22mmHg or higher obtained during the pre-study period.
- Patients currently not treated or on single-drug treatment for the elevated IOP are
eligible after a medication free period (wash-out) of:
1. 3 weeks for B-adrenergic antagonists
2. 2 weeks for adrenergic agonists
3. 5 days for cholinergics and oral carbonic anhydrase inhibitors.
Exclusion Criteria:
- History of acute angle closure.
- Severe trauma at any time.
- Intraocular surgery or argon laser trabeculoplasty within 6 months.
- Current use of contact lenses.
- History of severe dry eye syndrome.
- Ocular inflammation/infection with three months of inclusion.
- Any condition preventing reliable applanation tonometry.
- Unacceptable finding at pre-study ocular examination as specified in the Case Report
Forms.
- In Investigator regards monotherapy insufficient with respect to optic nerve head
and/or visual field status.
- Treatment of elevated IOP with any topical B-adrenergic antagonist regularly for a
period longer than 3 months and/or treatment at any time during 6 months prior to
study start.
- Cardiac failure, sinus bradycardia, second and third degree of atrio-ventricular
block.
- Bronchial asthma, history of bronchial asthma or chronic obstructive pulmonary
disease.
- Having participated in any other clinical study within the last month.
