Study Overview

• Status: Completed
• Conditions: 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. Qualifying Intra Ocular Pressure (IOPs) following wash-out, at baseline (Day 0 at anytime of the day) 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.

Subjects will receive one drop of investigational product (either A or B) in both the eyes every evening at approximately 10:00 pm ± 2 hours for 42 days.

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 (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 at six time points, i.e., at 00.00 hours (between 8:00am and 10:00 am), 04.00 hours (at 4 hours after 00.00 hours) and 08.00 hours ( at 8 hours after 00.00 hours) on Day 14 (week 2) and Day 42 (week 6) visits.

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:

1. Subjects willing and able to provide voluntary informed consent and to follow the protocol requirements
2. Male or non-pregnant females aged ≥18 years having body mass index (BMI) ≥ 17 calculated as weight in kg/height in m2.
3. Subjects with chronic open-angle glaucoma or ocular hypertension in both eyes.
4. Subjects requiring treatment of both the eyes and can discontinue use of all ocular hypotensive medication(s) or switch ocular hypotensive medications and undergo an appropriate washout period
5. Adequate wash-out period prior to baseline of any ocular hypotensive medication as per the table below (In order 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 subjects must have discontinued all ocular hypotensive medications for the minimum washout period
6. Baseline (Day 0/hour 0) IOP ≥ 22 mm Hg and ≤ 34 mm Hg in each eye and difference in IOP between the eyes is not greater than 5 mm Hg
7. Subject's IOP is likely to be controlled with monotherapy as per the discretion of the investigator
8. Baseline best-corrected visual acuity equivalent to 20/200 (6/60) or better in each eye

9. Women of child-bearing potential (defined as women physiologically capable of becoming pregnant, unless they are using an effective contraception method during dosing of the investigational product) practicing any two acceptable contraception methods

   Acceptable methods of contraception are:

   1. Oral or parenteral (injection) , patch, or implant) hormonal contraception which has been used continuously for at least one month prior to the first dose of study medication
   2. Intrauterine device (IUD) or intrauterine system IUS)
   3. A double barrier method of contraception (Condom and occlusive cap or condom and spermicidal agent)
   4. Male sterilization (at least six months prior to the screening, should be the sole male partner for that subject)

Note: - Stable myopia, strabismus and cataracts (as per investigator's discretion) will be allowed provided other inclusion/exclusion criteria are met
4. Current corneal abnormalities that would prevent accurate IOP readings with the Goldmann applanation tonometer
5. Functionally significant visual field loss
