July 23, 2025 updated by: Aerie Pharmaceuticals

A Long-Term Safety Study Evaluating the Safety and Systemic Exposure of AR-15512, a Cold Thermoreceptor Modulator, for the Treatment of Dry Eye Disease (COMET-4)

The purpose of this study is to evaluate the safety of topical ophthalmic 0.003% AR-15512 compared to its vehicle dosed twice daily (BID) in subjects with dry eye disease (DED) for 12 months.

Study Overview

Detailed Description

At the end of the Screening Visit, subjects will undergo a protocol-specified washout period for prohibited prior and concomitant therapies. At the Baseline Visit, subjects who qualify based on inclusion/exclusion criteria will be enrolled in the study and randomized in a 2:1 ratio to receive 0.003% AR-15512 or AR-15512 Vehicle administered as 1 drop in each eye twice a day for 365 days (12 months). At the end of the Day 365 visit, subjects will exit the study.

Aerie Pharmaceuticals was acquired by Alcon on November 22, 2022.

Primary Outcome Measures

Outcome Measure
Measure Description

Time Frame: Day 1 post-treatment, up to Day 365
A treatment-emergent adverse event was defined as any event that occurred or worsened on or after the day randomized study intervention was initiated. At each study visit, subjects were verbally asked by clinic staff to report any changes to any aspect of their ocular health. Ocular treatment-emergent adverse events reported by the subject or observed by the investigator were summarized by preferred term for overall incidence calculation. This was a subject-based assessment.

An examination of the back of the eye (dilated fundus exam) was performed by the investigator. Findings related to the vitreous (the clear gel that fills the space between the lens and the retina of the eyeball) were graded as Normal or Abnormal. Abnormal findings were categorized as clinically significant (CS) or not clinically significant (NCS). CS findings were defined at those that may interfere with study parameters or otherwise confound the data as determined by the investigator.

Number of Subjects With Clinically Significant Change From Baseline in Dilated Fundus Exam Results by Visit - Retina
Time Frame: Baseline (Day 1 pretreatment), Day 14, Day 90, Day 180, Day 270, Day 365
An examination of the back of the eye (dilated fundus exam) was performed by the investigator. Findings related to the retina (the light-sensitive tissue lining the back of the eye that converts light into electrical signals the brain then interprets as images) were graded as Normal or Abnormal. Abnormal findings were categorized as clinically significant (CS) or not clinically significant (NCS). CS findings were defined at those that may interfere with study parameters or otherwise confound the data as determined by the investigator.
Baseline (Day 1 pretreatment), Day 14, Day 90, Day 180, Day 270, Day 365
Number of Subjects With Clinically Significant Change From Baseline in Dilated Fundus Exam Results by Visit - Macula
Time Frame: Baseline (Day 1 pretreatment), Day 14, Day 90, Day 180, Day 270, Day 365
An examination of the back of the eye (dilated fundus exam) was performed by the investigator. Findings related to the macula (the round area at the center of the retina that provides central vision) were graded as Normal or Abnormal. Abnormal findings were categorized as clinically significant (CS) or not clinically significant (NCS). CS findings were defined at those that may interfere with study parameters or otherwise confound the data as determined by the investigator.
Baseline (Day 1 pretreatment), Day 14, Day 90, Day 180, Day 270, Day 365
Number of Subjects With Clinically Significant Change From Baseline in Dilated Fundus Exam Results by Visit - Optic Nerve
Time Frame: Baseline (Day 1 pretreatment), Day 14, Day 90, Day 180, Day 270, Day 365
An examination of the back of the eye (dilated fundus exam) was performed by the investigator. Findings related to the optic nerve (the nerve that transmits visual information from the retina to the brain) were graded as Normal or Abnormal. Abnormal findings were categorized as clinically significant (CS) or not clinically significant (NCS). CS findings were defined at those that may interfere with study parameters or otherwise confound the data as determined by the investigator.
Baseline (Day 1 pretreatment), Day 14, Day 90, Day 180, Day 270, Day 365
Number of Subjects With Clinically Significant Change From Baseline in Dilated Fundus Exam Results by Visit - Choroid
Time Frame: Baseline (Day 1 pretreatment), Day 14, Day 90, Day 180, Day 270, Day 365
An examination of the back of the eye (dilated fundus exam) was performed by the investigator. Findings related to the choroid (the layer of blood vessels and connective tissue between the white of the eye and retina) were graded as Normal or Abnormal. Abnormal findings were categorized as clinically significant (CS) or not clinically significant (NCS). CS findings were defined at those that may interfere with study parameters or otherwise confound the data as determined by the investigator.

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Minimum Plasma Concentration (Cmin)
Time Frame: Day 1, 14 and 90
From the blood samples collected from each subject, the minimum amount of AR-15512, the test drug, that may be present in the blood will be measured at a laboratory. Each measure will be recorded in pg/ml. Lower numbers represent better outcome.
Day 1, 14 and 90
Accumulation Ratio (Rcmax)
Time Frame: Day 1, 14 and 90
From the blood samples collected from each subject, the amount of AR-15512, the test drug, that may have accumulated in the blood will be measured in a laboratory. Each measure will be recorded as a number based on a ratio (e.g. Cmax Day 90 / Cmax Day 1). Lower numbers represent better outcome.
Day 1, 14 and 90
Time to Maximum Concentration (Tmax)
Time Frame: Day 1, 14 and 90
From the blood samples collected from each subject, the time at which the highest amount of AR-15512, the test drug, is measured in the blood will be measured in a laboratory. Each measure will be recorded in hours/min/sec.
Day 1, 14 and 90
Time to Last Detectable Concentration (Tlast)
Time Frame: Day 1, 14 and 90
From the blood samples collected from each subject, the time at which the last detectable amount of AR-15512, the test drug, is measured in the blood will be measured in a laboratory. Each measure will be recorded in hours/min/sec. Lower number represents better outcome.
Day 1, 14 and 90
Total Exposure (AUC0-last)
Time Frame: Day 1, 14 and 90
From the blood samples collected from each subject, the overall amount of AR-15512, the test drug, in the blood from the start of dose administration to the time after dosing at which the last quantifiable concentration was observed will be measured in a laboratory. Each measure will be recorded in µg*h/L. Lower numbers represent better outcome.
Day 1, 14 and 90
