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).

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Mean diurnal IOP at Day 8 (Stage 1)
Time Frame: Day 8 (8:00, 10:00, 12:00, 16:00)
Intraocular pressure (IOP) will be measured with a Goldmann tonometer. Diurnal IOP will be calculated as the average of the four measurements.

Mean diurnal IOP at Day 29 (Stage 2)
Time Frame: Day 29 (8:00, 10:00, 16:00)
