Trial 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. Read more about this study

About this study

Official title: A Multi Center, Open Label, Randomized, Two- Treatment, Single Dose, Crossover, Bioequivalence Study To Compare The Pharmacokinetics Of Marketed Product TobraDex® (Tobramycin And Dexamethasone Ophthalmic Ointment) To An Experimental Ophthalmic Sterile Ointment Containing Tobramycin 0.3% And Dexamethasone 0.1% W/W In Aqueous Humor In Patients Undergoing Indicated Cataract Surgery

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • cataract surgeryDrug

    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.

Study groups in NCT02734459
Study groupRoleWhat they receive
tobramycin and dexamethasone ophthalmic test ointmentExperimentalThe test drug (tobramycin is an aminoglycoside antibiotic and dexamethasone is a corticosteroid) will be administered in one eye before the cataract surgery.
Receives: Drug: cataract surgery
TobraDex® ointmentActive comparatorThe reference drug (tobramycin is an aminoglycoside antibiotic and dexamethasone is a corticosteroid) will be administered in another eye before the cataract surgery.
Receives: Drug: cataract surgery

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Concentration of dexamethasone in aqueous humor at different time points after administration of a single dose of each of the two drugs.

    A series of aqueous humor samples will be collected from each eye of each patient.

    Measured: 30 min - 8 hours

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing cataract surgery in people with Bilateral Cataract, run by Semler Research Center Pvt. Ltd..

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Apr 2016. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Concentration of dexamethasone in aqueous humor at different time points after administration of a single dose of each of the two drugs. (time frame: 30 min - 8 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Apr 2016.
