A Bioequivalence Study to Compare the Pharmacokinetics (PK) Of Marketed Product TobraDex® To An Experimental Ophthalmic Sterile Ointment Containing Tobramycin And Dexamethasone In Aqueous Humor In Patients Undergoing Indicated Cataract Surgery

NCT ID: NCT02734459

Last Updated: 2016-04-12

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE3
• Total Enrollment: 756 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2013-11-30
• Study Completion Date: 2016-03-31

Brief Summary

Each patient will be randomized to receive one dose of the test article in one eye and one dose of the reference formulations in the contralateral eye. One eye will be selected as the initial eye for cataract surgery and aqueous humor collection and hence will be dosed and operated on first. Followed by the second eye which will be dosed no early than a week followed by aqueous humor collection as per specified time points and no later than 35 days following the first eye again prior to the cataract surgery.

Conditions

Bilateral Cataract

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: CROSSOVER
• Blinding Strategy: NONE

Study Groups

tobramycin and dexamethasone ophthalmic test ointment

The test drug (tobramycin is an aminoglycoside antibiotic and dexamethasone is a corticosteroid) will be administered in one eye before the cataract surgery.

Group Type: EXPERIMENTAL

cataract surgery

Intervention Type: DRUG

the patient will be dosed with the study drug into the "V" pocket is formed between the eye ball and the lower eyelid during cataract surgery.

TobraDex® ointment

The reference drug (tobramycin is an aminoglycoside antibiotic and dexamethasone is a corticosteroid) will be administered in another eye before the cataract surgery.

Group Type: ACTIVE_COMPARATOR

cataract surgery

Intervention Type: DRUG

the patient will be dosed with the study drug into the "V" pocket is formed between the eye ball and the lower eyelid during cataract surgery.
