Aramis Biosciences Completes Enrollment of its Phase II Clinical Trial Evaluating A197 for the Treatment of Dry Eye Disease

Topline proof of concept data anticipated by Q1 2023

Boston, MA (November 3, 2022) – Aramis Biosciences, Inc., a clinical-stage immuno-ophthalmology biopharmaceutical company, today announced the completion of enrollment in its Phase II proof of concept clinical trial evaluating A197, a novel, first-in-class, topical immunomodulatory agent for the treatment of dry eye disease.

“We are very pleased to have completed the enrollment of our Phase II study for A197 and look forward to topline data by the end of the first quarter of 2023,” said David S. Tierney, M.D., Aramis Biosciences’ President and CEO. “We would like to thank the patients who enrolled in the study as well as the clinical investigators and other research staff who have worked diligently to get us to this point.”

About A197-CS-201

The Phase II, multicenter, double-masked, randomized, vehicle-controlled, parallel-group clinical trial (NCT05238597) is designed to evaluate the safety and tolerability as well as explore the efficacy of two doses of A197 ophthalmic solution in 207 patients with dry eye disease. The primary endpoint of the trial measures the change from baseline in corneal fluorescein staining with a key secondary endpoint evaluating eye dryness symptoms using the visual analog scale (VAS). The clinical trial is being conducted across 24 centers in the United States.

About Dry Eye Disease

Dry eye disease is an extremely common, chronic, immune-mediated disease driven and perpetuated by a distinct subset of pro-inflammatory T helper cells, resulting in epithelial cell damage and ocular discomfort. While 17.8 million Americans have been diagnosed with dry eye disease, fewer than 1 million (1 in 20) are currently being treated with an FDA-approved product; presumably due to questionable efficacy and tolerability limitations. There are many risk factors including advanced age, female gender, autoimmune disorders, diabetes, certain medications, increased screen time, LASIK, contact lens use and environmental factors such as pollution.

Dry eye disease is best characterized as an immunological response originating from an imbalance in the protective immunoregulatory versus pro-inflammatory pathways of the ocular surface. Chronic dry eye is believed to be the result of a ‘vicious cycle’ of inflammatory responses perpetuated by the resistance of a pathogenic subset of pro-inflammatory T helper cells to suppression by regulatory T cells (Treg).
