Bioequivalence Study With Clinical Endpoint Comparing Brinzolamide 1% Ophthalmic Suspension to Azopt® 1% Ophthalmic Suspension In the Treatment of Chronic Open Angle Glaucoma or Ocular Hypertension in Both Eyes

Glaucoma Clinical Trial

Official title:
A Multicentre, Double Blind, Active Controlled, Parallel Group, Two Arm, Bioequivalence Study With Clinical Endpoint Comparing Brinzolamide 1% Ophthalmic Suspension (Manufactured by Indoco Remedies Ltd. for Watson Pharma Pvt Ltd.), to Brinzolamide (Azopt®) 1% Ophthalmic Suspension of Alcon Laboratories, Inc., In the Treatment of Chronic Open Angle Glaucoma or Ocular Hypertension in Both Eyes

Status Completed

Clinical Trial Summary

This is a randomized, double blind, two-arm, parallel group, active controlled bioequivalence study, at multiple clinical trial sites designed to demonstrate bioequivalence of Brinzolamide 1% ophthalmic suspension (manufactured by Indoco Remedies Ltd. for Watson Pharma Pvt Ltd.), to Brinzolamide (Azopt®) 1% ophthalmic suspension of Alcon Laboratories, Inc. in the treatment of chronic open angle glaucoma or ocular hypertension in both eyes.

Clinical Trial Description

Study will be conducted in adult subjects, above 18 years inclusive, males and non pregnant females, diagnosed with chronic open angle glaucoma or ocular hypertension in both eyes. Qualifying Intra Ocular Pressure (IOPs) following wash-out, at baseline (Day 0/hour 0 i.e., 8:00 am) should be ≥ 22 milli meter mercury (mm Hg) and ≤ 34 mm Hg in each eye and any asymmetry of IOP between the eyes no greater than 5 mm Hg.

Each study subject will use one drop of test or reference Ophthalmic Suspension in both the eyes three times daily at approximately 8:00am, 04:00 pm and 10:00 pm for 42 days (6 weeks). The dose and mode of treatment chosen in this study is the dosage approved by United States Food and Drug administration (US FDA) for use in treatment of patients of Chronic Open Angle Glaucoma.

The study subjects will undergo clinical evaluations throughout the study in order to assess efficacy and safety. Study subject primary endpoint evaluation will be assessed after 2 weeks (14 days) and 6 weeks (42 days) of treatment for each study subject deemed eligible for evaluation, (i.e., at Visit III - Day 14 ± 2 days and Visit IV - Day 42 ± 3 days).

The primary bioequivalence comparison is between the test and reference products for the mean difference in intraocular pressure (IOP) of both eyes at four time points, i.e., at approximately 8:00 am and 10:00 am at the Day 14 (± 2 days) and Day 42 (± 3 days) visits. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
