Official title: A Two-Arm Multicenter Clinical Trial to Investigate Efficacy and Safety of FID123472 Ophthalmic Solution Compared With Vehicle in Adult Subjects With Ocular Redness
The purpose of this study is to evaluate the efficacy and safety of an investigational ophthalmic solution in adults with ocular redness due to minor eye irritations.
Read the detailed description
Eligible subjects will be expected to attend a total of 3 in-office study visits over a period of approximately 1 week. Subjects will receive a single dose of the study treatment in each eye on Day 1 (Visit 2). Eye redness will be assessed before and after instillations at prespecified timepoints.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change from baseline in investigator-assessed ocular redness at 15 minutes post-instillation on Day 1 (Visit 2)
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)
Change from baseline in investigator-assessed ocular redness at 840 minutes (14 hours) post-instillation on Day 2 (Visit 3)
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); 840 minutes (14 hours) post-instillation (Day 2)
Secondary outcomes (2)
Change from baseline in investigator-assessed ocular redness at 1 minute post-instillation on Day 1 (Visit 2)
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)
Change from baseline in investigator-assessed ocular redness at 960 minutes (16 hours) post-instillation on Day 2 (Visit 3)
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); 960 minutes (16 hours) post-instillation (Day 2)

Primary outcome
Change from baseline in investigator-assessed ocular redness at 15 minutes post-instillation on Day 1 (Visit 2)
Time frame: Baseline (Day 1 pretreatment); 15 minutes post-instillation (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.

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 9 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 9 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 (Visit 2) (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.
