About this study

Official title: Hypotensive Efficacy of Topical Prophylaxis for Intraocular Pressure Spikes Following Intravitreal Injections of Anti-vascular Endothelial Growth Factor Agents

In this study, investigators will be examining the intraocular pressure lowering effect of brimonidine 0.15% when administered 20min prior to intravitreal anti-VEGF injection.

Read the detailed description

A total of 55 consecutive patients undergoing anti-VEGF intravitreal injections (received ≥1 treatments) for age-related macular degeneration (AMD), diabetic macular edema (DME) or macula edema secondary to branch retinal vein occlusion (BRVO) will be prospectively recruited between December 2016 and July 2017. Patients will be randomly assigned based on a pre-determined allocation sequence to receive topical brimonidine tartrate 0.15% (Alphagan® P; Allergan, Inc) during either the first or second of two consecutive visits. A standard protocol for sterile preparation with topical 5% povidone-iodine solution will be followed. Pre-injection IOP measurements will be recorded prior to the instillation of dilating agents and brimonidine tartrate. A total of three IOP measurements will be taken by certified ophthalmic technicians at immediately after the injection (T0), 10 minutes after (T10) and 20 minutes after (T20) injection.

What participants receive

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

  • topical brimonidine tartrate 0.15% (Alphagan® P; Allergan, Inc)Drug

    The rapid hypotensive effects of topical alpha2-agonists such as brimonidine tartrate on decreasing aqueous production and increasing uveoscleral outflow, in addition to their neuroprotective properties, make them an attractive option for prophylactic treatment of post-injection IOP spikes.

Questions about this trial

What is this clinical trial studying?

A study testing topical brimonidine tartrate 0.15% (Alphagan® P; Allergan, Inc) in people with Post-Injection Intraocular Pressure Spikes, run by University of Toronto.

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 1 inclusion and 6 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 1 May 2018. 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.

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?

Change in Post-Injection Intraocular Pressure Spike (time frame: Change from immediately, 10 minutes and 20 minutes after injection). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03513172, which also lists 6 linked publications.

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 1 May 2018.
