January 23, 2026 updated by: Alcon Research

A Phase 3b Open-Label Study Designed to Evaluate Tear Production Stimulated by 0.003% AR-15512

The purpose of this study is to evaluate tear production following acute administration of AR-15512 ophthalmic solution 0.003% (0.003% AR-15512) in subjects with dry eye disease (DED).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Qualified subjects will attend a single visit.

This is a Phase 3b, 2-stage study. In Stage 1, approximately 40 subjects will be enrolled, after which the study will be paused and an interim analysis will be conducted. Results from the Stage 1 analysis will help inform the design of Stage 2. An additional 40 subjects are planned for Stage 2.

For both stages, the primary endpoint and analysis will remain the same. Stage 2 will be tested independently with no pooling of data between stages.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Key Inclusion Criteria:

  • Within the last 12 months, have a previous history of dry eye disease, either clinician diagnosed or patient reported.
  • Within the last 6 months, have used, or desired to use artificial tears for dry eye symptoms.
  • Corrected visual acuity score of 20/200 or better in both eyes.
  • Good general and ocular health, as determined by the investigator using medical history, ophthalmic examination and history.
  • Other protocol specified inclusion criteria may apply.

Key Exclusion Criteria:

  • Current evidence of any clinically significant ophthalmic disease other than dry eye (for example, glaucoma or macular degeneration).
  • History of ocular surgery within 1 year of the Study Visit.
  • Use of contact lenses in either eye within 7 days of the Study Visit.
  • Use of lid hygiene (all forms of lid care) or heat masks within 7 days of the Study Visit.
  • Use of any topical ocular anti-inflammatory medications, any topical ocular corticosteroid, or any non-steroidal-anti-inflammatory agents within 30 days of the Study Visit.
  • Used artificial tears within 2 hours of the Study Visit.
  • Other protocol-specified exclusion criteria may apply.

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 Change From Baseline in Tear Meniscus Height (TMH) at Minute 3 - Stage 1
Time Frame: Day 1, Minute 0 pre-instillation (Baseline); Day 1, Minute 3 post-instillation
TMH (the distance between the line of reflection along the top of the tear prism to the edge of the central lower eyelid) was measured pre-instillation and post-instillation in micrometers using optical coherence tomography (OCT), a non-invasive imaging test that uses light waves to take cross-section pictures of the eye. A normal TMH range falls between 200 and 400 micrometers. Measurements below this range may indicate dry eye disease. A positive change value indicates an improvement. One eye (study eye, defined as the left eye) contributed data to the analysis.
Day 1, Minute 0 pre-instillation (Baseline); Day 1, Minute 3 post-instillation
Mean Change From Baseline in Tear Meniscus Height (TMH) at Minute 3 - Stage 2
Time Frame: Day 1, Minute 0 pre-instillation (Baseline); Day 1, Minute 3 post-instillation
