A Randomized, Double-blind, Multiple Dose, Parallel-group, Two-arm, Multicenter, Bioequivalence Study With Clinical Endpoint Comparing Bimatoprost Ophthalmic Solution 0.01% and LUMIGAN® (Bimatoprost Ophthalmic Solution) 0.01% in the Treatment of Subjects With Chronic Open-angle Glaucoma or Ocular Hypertension in Both Eyes

This is a randomized, double-blind, two-treatment, single-period, parallel design, multiple dose at multiple clinical trial sites designed to demonstrate bioequivalence with clinical endpoint in subjects with chronic open-angle glaucoma or ocular hypertension in both eyes.

Test Product - Bimatoprost ophthalmic solution, 0.01% of Amneal EU, Limited Reference Product - LUMIGAN® (bimatoprost ophthalmic solution) 0.01% of Allergan, Inc.

Study Overview

• Status: Recruiting
• Conditions: Ocular Hypertension; Glaucoma, Open-Angle
• Intervention / Treatment: Drug: Test - Bimatoprost 0.01% Ophthalmic Solution; Drug: Reference - LUMIGAN® (Bimatoprost 0.01% Ophthalmic Solution)

Detailed Description

Subjects with chronic open-angle glaucoma or ocular hypertension in both the eyes and meeting all the mentioned inclusion criteria and none of the exclusion criteria will be identified. At baseline (Day 0), subjects qualifying Intra Ocular Pressure (IOPs) following wash-out, with difference between the IOP in left and right eyes not being more than 5 mm Hg, will be randomized.

Subjects will instill 1 drop of study drug (either T or R) in both eyes every evening at approximately 10:00 pm for 42 days.

The study subjects will undergo clinical evaluations throughout the study in order to assess safety and efficacy. Primary endpoint evaluation will be assessed after 2 weeks (Day 14) and 6 weeks (Day 42) of treatment for each study subject deemed eligible for evaluation.

The primary bioequivalence comparison is between the test and reference products for the mean difference in intraocular pressure (IOP) of both eyes between the two treatment groups.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 18 years and older (ADULT, OLDER_ADULT)
• Accepts Healthy Volunteers: No
• Genders Eligible for Study: All

Description

Inclusion Criteria:

• Subjects willing and able to provide voluntary informed consent and to follow protocol requirements.
• Male or females aged ≥18 years.
• Subjects having body mass index (BMI) ≥18.50 kg/m2.
• Subjects with chronic open-angle glaucoma or ocular hypertension in both eyes.
• Subjects requiring treatment of both eyes and able to discontinue the use of all ocular hypotensive medication(s) or switch ocular hypotensive medications and undergo appropriate washout period.
• Adequate washout period prior to baseline of any ocular hypotensive medications as per the table below (to minimize potential risk to subjects due to intraocular pressure (IOP) elevations during the washout period, the Investigator may choose to substitute a parasympathomimetic or carbonic anhydrase inhibitor in place of a sympathomimetic, alpha-agonist, beta-adrenergic blocking agent, or prostaglandin; however, all the subjects must have discontinued their ocular hypotensive medications for the minimum washout period.
• Baseline (Day 0/hour 0) IOP ≥22 mm Hg and <35 mm Hg in each eye,
• Subjects' IOP is likely to be controlled with monotherapy as per the Investigator's discretion.
• Baseline best corrected visual acuity equivalent to Snellen acuity of 20/100 or better in each eye, using a logarithmic visual acuity chart for testing at 10 feet (3 meters).

• Current corneal abnormalities that would prevent accurate IOP readings with Goldmann applanation tonometer.

• Severe retinal disease or other severe ocular pathology, such as glaucomatous damage with a cup/disk ratio greater than 0.8 (not including physiological cupping in the Investigators' opinion) or split fixation
• Chronic use of any systemic medication that may affect IOP with less than 3 months stable dosing regimen (i.e., sympathomimetic agents, beta-adrenergic blocking agents, alpha-agonists, alpha-adrenergic blocking agents, calcium channel blockers, angiotensin-converting enzyme inhibitors, etc.)
• Central Corneal thickness (CCT) <450 microns or >650 microns
• Known history or presence of any uncontrolled systemic disease (e.g., cardiovascular disease, hypertension, diabetes mellitus, hepatic impairment, etc.)
• History of recurrent ocular seasonal allergies within the past 2 years
• Any other medical condition or serious intercurrent illness that, in the Investigator's opinion, may make it undesirable for the subject to participate in the study and would limit adherence to the study requirements
