About this study

Official title: A Multicenter, Randomized, Vehicle-Controlled Evaluation of the Efficacy and Safety of FID 123472 Ophthalmic Solution for the Reduction of Ocular Redness in Adult Subjects

The purpose of this study is to evaluate the efficacy and safety of an investigational ophthalmic solution in adults with ocular redness caused by minor eye irritations.

Read the detailed description

Eligible subjects will be expected to attend a total of 6 in-office study visits over a period of approximately 10 weeks. Subjects will receive a single dose of study treatment in each eye (either Apraclonidine 0.125% UDPF or Vehicle) on Day 1, after which subjects will be instructed to self-administer one drop in each eye twice daily at home for a total of approximately 8 weeks (Days 2-55), with the last dose administered on Day 56 in office. Subjects will then return for the final study visit on Day 63, following a 1-week treatment discontinuation. Eye redness will be assessed before and after instillation at prespecified timepoints.

What is being measured

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

  1. Change from baseline in investigator-assessed ocular redness at 15 minutes post-instillation on Day 1

    Ocular redness will be assessed by the investigator and recorded per the Ora Calibra® Ocular Hyperemia Scale, which ranges from 0 to 4 in half-point increments (0.0 = none; 1.0 = mild redness; 2.0 = moderate redness; 3.0 = severe redness; and 4.0 = extremely severe redness). Change from baseline, calculated as post-instillation minus baseline score, can range between -4 and +2.5. Positive values indicate increased ocular redness (worsening), zero indicates no change, and negative values indicate improvement (decrease in severity). This is a co-primary endpoint.

    Measured: Baseline (Day 1 pretreatment); 15 minutes post-instillation (Day 1)

  2. Change from baseline in investigator-assessed ocular redness at 600 minutes post-instillation on Day 1

    Ocular redness will be assessed by the investigator and recorded per the Ora Calibra® Ocular Hyperemia Scale, which ranges from 0 to 4 in half-point increments (0.0 = none; 1.0 = mild redness; 2.0 = moderate redness; 3.0 = severe redness; and 4.0 = extremely severe redness). Change from baseline, calculated as post-instillation minus baseline score, can range between -4 and +2.5. Positive values indicate increased ocular redness (worsening), zero indicates no change, and negative values indicate improvement (decrease in severity). This is a co-primary endpoint.

    Measured: Baseline (Day 1 pretreatment); 600 minutes post-instillation (Day 1)

Secondary outcomes (4)
  1. Change from baseline in investigator-assessed ocular redness at 1 minute post-instillation on Day 1

    Ocular redness will be assessed by the investigator and recorded per the Ora Calibra® Ocular Hyperemia Scale, which ranges from 0 to 4 in half-point increments (0.0 = none; 1.0 = mild redness; 2.0 = moderate redness; 3.0 = severe redness; and 4.0 = extremely severe redness). Change from baseline, calculated as post-instillation minus baseline score, can range between -4 and +2.5. Positive values indicate increased ocular redness (worsening), zero indicates no change, and negative values indicate improvement (decrease in severity).

    Measured: Baseline (Day 1 pretreatment); 1 minute post-instillation (Day 1)

  2. Change from baseline in investigator-assessed ocular redness at 720 minutes post-instillation on Day 1

    Ocular redness will be assessed by the investigator and recorded per the Ora Calibra® Ocular Hyperemia Scale, which ranges from 0 to 4 in half-point increments (0.0 = none; 1.0 = mild redness; 2.0 = moderate redness; 3.0 = severe redness; and 4.0 = extremely severe redness). Change from baseline, calculated as post-instillation minus baseline score, can range between -4 and +2.5. Positive values indicate increased ocular redness (worsening), zero indicates no change, and negative values indicate improvement (decrease in severity).

    Measured: Baseline (Day 1 pretreatment); 720 minutes post-instillation (Day 1)

  3. Change from baseline in investigator-assessed ocular redness at 30 seconds post-instillation on Day 1

    Ocular redness will be assessed by the investigator and recorded per the Ora Calibra® Ocular Hyperemia Scale, which ranges from 0 to 4 in half-point increments (0.0 = none; 1.0 = mild redness; 2.0 = moderate redness; 3.0 = severe redness; and 4.0 = extremely severe redness). Change from baseline, calculated as post-instillation minus baseline score, can range between -4 and +2.5. Positive values indicate increased ocular redness (worsening), zero indicates no change, and negative values indicate improvement (decrease in severity).

    Measured: Baseline (Day 1 pretreatment); 30 seconds post-instillation (Day 1)

  4. Number of subjects who achieve prespecified improvements from baseline in investigator-assessed ocular redness score in both eyes at 30 seconds post-instillation on Day 1

    Ocular redness will be assessed by the investigator and recorded per the Ora Calibra® Ocular Hyperemia Scale, which ranges from 0 to 4 in half-point increments (0.0 = none; 1.0 = mild redness; 2.0 = moderate redness; 3.0 = severe redness; and 4.0 = extremely severe redness). The 30-second score will be compared to the baseline score. The number of subjects with improvements as prespecified in the protocol will be reported.

    Measured: Baseline (Day 1 pretreatment); 30 seconds post-instillation (Day 1)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Apraclonidine Ophthalmic Solution, 0.125% Unit Dose Preservative Free in people with Ocular Hyperemia, run by Alcon Research at 5 sites in United States.

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 7 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: looking for participants now, as of the sponsor's last update on 16 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in United States. 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. Some participants in this study may receive a placebo. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Alcon Call Center (1-888-451-3937, alcon.medinfo@alcon.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from baseline in investigator-assessed ocular redness at 15 minutes post-instillation on Day 1 (time frame: Baseline (Day 1 pretreatment); 15 minutes post-instillation (Day 1)). The study lists 2 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 16 Oct 2026.
