About this study

Official title: A Phase II, Prospective, Two-Stage, Double-Masked, Randomized, Multi-Center, Controlled, Dose-Response Study Assessing the Safety and Ocular Hypotensive Efficacy of AR-17043 and PG043 (AR-17043/Latanoprost) Ophthalmic Solutions in Subjects With Elevated Intraocular Pressure

The purpose of this two-stage clinical trial is to assess the safety and hypotensive efficacy of AR-17043 and PG043 ophthalmic solutions in subjects with open-angle glaucoma (OAG) or ocular hypertension (OHT).

Read the detailed description

During Stage 1, approximately 100 adult subjects with OAG or OHT will be randomized to 5 arms: 3 different concentrations of AR-17043, placebo comparator, or netarsudil 0.02% (Rhopressa®) for a treatment duration of 7 days.

During Stage 2, approximately 350 adult subjects with OAG or OHT will be randomized to 5 arms: low and high concentrations of PG043 (AR-17043/latanoprost 0.005%), AR-17043 high concentration, latanoprost, or netarsudil 0.02%/latanoprost 0.005% (Rocklatan®) for a treatment duration of 28 days.

What is being measured

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

  1. Mean diurnal IOP at Day 8 (Stage 1)

    Intraocular pressure (IOP) will be measured with a Goldmann tonometer. Diurnal IOP will be calculated as the average of the four measurements.

    Measured: Day 8 (8:00, 10:00, 12:00, 16:00)

  2. Mean diurnal IOP at Day 29 (Stage 2)

    Intraocular pressure (IOP) will be measured with a Goldmann tonometer. Diurnal IOP will be calculated as the average of the three measurements.

    Measured: Day 29 (8:00, 10:00, 16:00)

Secondary outcomes (10)
  1. Mean IOP at each post-treatment timepoint (Stage 1)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing AR-17043 Ophthalmic Solution, PG043 Ophthalmic Solution and Latanoprost 0.005% Ophthalmic Solution in people with Open Angle Glaucoma and Ocular Hypertension, run by Alcon Research at 12 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?

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 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Mean diurnal IOP at Day 8 (Stage 1) (time frame: Day 8 (8:00, 10:00, 12:00, 16:00)). 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 18 Nov 2025.
