About this study

Official title: Non-inferiority of Nanodropper-mediated Microdrops vs. Standard Drops of 0.5% Timolol Maleate in Patients With Open-angle Glaucoma or Ocular Hypertension

The purpose of this study is to evaluate the effect of microdrops vs. standard eyedrops of 0.5% timolol maleate in adults with primary open-angle glaucoma or ocular hypertension in terms of intraocular pressure-lowering efficacy and cardiovascular side effects.

Read the detailed description

This randomized, single-masked, parallel study aims to evaluate the safety and efficacy of microdrops of 0.5% timolol maleate administered with Nanodropper (experimental intervention) compared to standard drops of 0.5% timolol maleate (active comparator) in patients with primary open-angle glaucoma (OAG) or ocular hypertension (OHT) at Aravind Eye Hospital. At the beginning of the test day, baseline (pre-drug) intraocular pressure (IOP), resting heart rate (HR), and resting systolic and diastolic blood pressure (BP) measurements will be collected. Participants will be randomized to receive standard eyedrops or microdrops of 0.5% timolol maleate (one drop per eye), which will be administered by a trained technician at t = 0. IOP, HR, and BP measurements will be repeated by a masked investigator at t = 1, 2, 5, and 8 hours after drug administration.

Being tested
Nanodropper adaptor, Original eyedrop bottle/No Nanodropper

What participants receive

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

  • Nanodropper adaptorDevice

    The Nanodropper adaptor is a sterile medical device that reduces the size of administered eyedrops by coupling to the original bottle.

  • Original eyedrop bottle/No NanodropperOther

    The original eyedrop bottle dispenses standard eyedrops.

Questions about this trial

What is this clinical trial studying?

A study testing Nanodropper adaptor and Original eyedrop bottle/No Nanodropper in people with Glaucoma and Glaucoma, Open-Angle, run by Nanodropper, Inc. at 2 sites in India.

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 5 inclusion and 8 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 18 Jan 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in India. Whether a site is taking part right now should be confirmed with that site. See every site.

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.

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?

Intraocular pressure (mm Hg) (time frame: 1 hour after drug administration). The study lists 4 primary outcomes in all. 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 18 Jan 2023.
