Trial Summary

What is the purpose of this trial?

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).

Do I have to stop taking my current medications for the trial?

You need to stop using any topical ocular anti-inflammatory medications, corticosteroids, or non-steroidal anti-inflammatory agents at least 30 days before the study visit. The protocol does not specify other medications, so check with the trial team for more details.

What data supports the idea that AR-15512 Eye Drops for Dry Eye Syndrome is an effective drug?

The available research shows that AR-15512 was evaluated in a study called COMET-1, which was a randomized, vehicle-controlled Phase 2b study. This means that the study compared AR-15512 to a placebo (a substance with no therapeutic effect) to see if it was effective in treating dry eye disease. The study found that AR-15512, which works by targeting a specific receptor in the eye, was a potential therapy for improving symptoms of dry eye disease. This suggests that AR-15512 could be an effective treatment for people suffering from this condition. ^{1 2 3 4 5}

What safety data is available for AR-15512 eye drops for dry eye syndrome?

The provided research does not contain specific safety data for AR-15512 eye drops. It includes studies on other compounds like SA001, AR-12286, and AR-13324, as well as the effects of preservatives like benzalkonium chloride in eye drops. None of these directly address the safety of AR-15512. ^{6 7 8 9 10}

Is the drug AR-15512 a promising treatment for dry eye syndrome?

Yes, AR-15512 is a promising drug for treating dry eye syndrome. It was tested in a study and showed potential as a therapy for improving symptoms of dry eye disease, which can greatly affect a person's quality of life. ^{1 2 3 11 12}

Findings from Research

In a Phase 2b study involving patients with dry eye disease, the 0.003% concentration of AR-15512 showed significant improvements in eye symptoms and quality of life measures over 12 weeks, particularly at Days 14, 28, and 84.

While the study did not meet its predefined co-primary endpoints, AR-15512 was associated with early and sustained improvements in eye surface health and symptoms, with the most common side effects being mild burning and stinging upon application.

In a study of 2619 individuals with symptomatic dry eye in Japan, 1876 participants did not use any eye drops, highlighting a significant gap in treatment for this condition.

The most commonly used eye drops were artificial tears (53.4%), but various risk factors, such as age and screen exposure time, were identified that contributed to the lack of eye drop use, suggesting areas for targeted intervention.

In a study of 168 patients with moderate dry eye, the HP-Guar gellable lubricant eye drops significantly reduced corneal staining by an average of 4.1 units (62% improvement) after 28 days, indicating effective relief of dry eye signs.

Patients also reported significant symptomatic relief across all six ocular discomfort measures, demonstrating that the eye drops not only improved objective signs but also enhanced subjective comfort.

In a study of 50 participants with moderate ocular dryness, Systane(R) Lubricating Eye Drops significantly improved tear film break-up time (TFBUT) after 28 days of use, indicating better eye lubrication.

Participants reported significant relief from all six ocular discomfort symptoms, demonstrating both objective and subjective efficacy of Systane(R) in treating moderate ocular dryness.

Dry eye syndrome is a common but often underdiagnosed condition that can lead to chronic pain and increased risk of ocular surface disease, highlighting the need for greater awareness and appropriate interventions.

Experts recommend using preservative-free artificial tear products as the first-line treatment for all levels of dry eye, as they are safer and more effective for patients, ensuring better ocular surface health.

SA001, a new formulation of rebamipide, showed significantly higher systemic exposure of rebamipide compared to conventional rebamipide, with plasma concentrations up to 11.94 times higher at the highest dose, indicating enhanced efficacy potential for treating dry eye disease.

The study demonstrated that SA001 was rapidly absorbed and well-tolerated, with no significant adverse events reported, supporting its safety for further clinical development.

In a study involving 18 normal adult volunteers, both formulations of 0.5% AR-12286 Ophthalmic Solution significantly reduced intraocular pressure (IOP) by 3 to 7 mm Hg, demonstrating its efficacy as a treatment for ocular hypertension.

The formulations showed low systemic absorption, with most participants having no measurable drug levels in their blood, and the ocular side effects reported were mild and short-lived, indicating a favorable safety profile.

Benzalkonium chloride (BAK), a common preservative in eye drops, significantly inhibits mitochondrial function in human corneal epithelial cells and trabecular meshwork cells, leading to potential ocular toxicity, particularly at concentrations used in eye drops.

The study found that BAK is especially harmful to cells with mitochondrial mutations, such as those associated with Leber hereditary optic neuropathy (LHON), suggesting that patients with mitochondrial deficiencies should avoid BAK-containing eye drops to prevent exacerbating their condition.

In a phase 1 clinical trial involving 18 healthy volunteers, the ophthalmic solution AR-13324 (0.02%) showed no significant systemic absorption, with only one subject showing a minimal level of the metabolite AR-13503, indicating a favorable safety profile.

AR-13324 significantly reduced intraocular pressure by up to 6 mm Hg in normotensive subjects, demonstrating its potential efficacy as an ocular hypotensive treatment, with effects greater than those typically seen with other therapies.

Chronic use of eye drops containing preservatives, particularly benzalkonium chloride (BAC), can lead to significant damage in ocular tissues, including inflammation, fibrosis, and cell loss.

To reduce these harmful effects, preservative-free eye drop formulations are recommended as a safer alternative for treating eye conditions.

In a survey of 2048 physical education and sports science graduates, the prevalence of diagnosed dry eye syndrome (DES) was found to be 2.9% in men and 9.3% in women, while subjective symptoms were reported at 14.8% in men and 39.8% in women, indicating a significant gender difference in prevalence.

The study identified that contact lens use and daily screen viewing time of 4 hours or more were strongly associated with higher odds of experiencing DES, suggesting that addressing these factors could improve ocular health and quality of life for graduates.

The reclassification of dry eye disease (DED) patients from the 2006 to the 2016 diagnostic criteria resulted in a significant increase in the prevalence of definite DED, from 38.8% to 66.8% among 250 patients studied.

Most patients previously classified as having probable DED (79.8%) were reclassified as having definite DED under the new criteria, indicating a shift in how DED is diagnosed and potentially affecting treatment approaches.
