Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A 6-Month, Randomized, Double-Masked Comparison of PhXA41 With Timolol in Patients With Open Angle Glaucoma or Ocular Hypertension. A Multi-Centre Study in Scandinavia

Further study details as provided by Pfizer:

Primary Outcome Measures:
  • to demonstrate the IOP-reducing effect of PhXA41 is comparable to that of timolol at the end of 6 months of treatment. [ Time Frame: 6 mos ]

Secondary Outcome Measures:
  • to demonstrate the IOP-reducing effect of PhXA41 administered in the morning is equivalent the effect of PhXA41 administered in the evening [ Time Frame: 6 mos ]

Enrollment: 267
Study Start Date: November 1992
Study Completion Date: December 1993
Primary Completion Date: December 1993 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Timolol Drug: timolol
One drop in the affected eye every morning from the morning bottle and one drop every evening from the evening bottle.
Experimental: PhXA41 Drug: PhXA41
One drop in the affected eye every morning from the morning bottle and one drop every evening from the evening bottle


Ages Eligible for Study:   40 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

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.

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.
