Aldeyra Therapeutics Announces Positive Top-Line Symptom and Sign Results from Run-In Cohort of Phase 3 TRANQUILITY Trial in Dry Eye Disease

Posted on January 24, 2021 at 6:55 AM

LEXINGTON, Mass.--(BUSINESS WIRE)--Aldeyra Therapeutics, Inc. (Nasdaq: ALDX) (Aldeyra) today announced positive top-line symptom, redness, and Schirmer’s test results from the run-in cohort of the Phase 3 TRANQUILITY clinical trial in patients with dry eye disease.


The double-masked, single-center, parallel-group run-in cohort enrolled 23 patients: 12 patients were randomized to receive 0.25% reproxalap ophthalmic solution and 11 patients were randomized to receive vehicle ophthalmic solution. Patients received four doses one day prior to and two doses on the day of exposure to a 90-minute dry eye chamber with minimal humidity, high airflow, and forced visual tasking.


Over all time points in aggregate in the dry eye chamber, reproxalap was observed to be statistically superior to vehicle for the two assessed symptoms, visual analog scale (VAS) ocular dryness score (p = 0.001) and ocular discomfort score (p < 0.0001) in the run-in cohort of TRANQUILITY. Consistent with previously announced allergen chamber Phase 2 clinical trial results, reproxalap demonstrated statistically significant improvement over vehicle (p = 0.03) in ocular redness, an objective sign of dry eye disease. Improvement in ocular symptoms and redness occurred within minutes after reproxalap dosing. Following acute dosing on the day prior to the dry eye chamber, Schirmer test scores were directionally in favor of reproxalap over vehicle, and reproxalap was statistically superior to vehicle in improvement in VAS dryness score (p = 0.003), ocular discomfort 4-symptom questionnaire (OD4SQ) dryness score (p = 0.006), OD4SQ grittiness score (p = 0.006), and OD4SQ discomfort score (p = 0.003). Consistent with clinical experience in over 1,100 patients, no adverse findings on safety assessments were observed, and reproxalap was well-tolerated. 


“The symptom improvement observed in the run-in cohort of TRANQUILITY announced today support the first-line potential use of reproxalap in dry eye disease, and represent the first results from an ophthalmic solution for chronic use that demonstrate activity acutely following drug administration,” stated Todd C. Brady, M.D., Ph.D., President and Chief Executive Officer of Aldeyra. “The activity of reproxalap in reducing ocular redness, initially demonstrated in the allergen chamber Phase 2 clinical trial, was also observed in the dry eye chamber run-in results of TRANQUILITY, and we look forward to initiating enrollment of the main cohort.”


Among many patients and physicians, current dry eye disease therapies are considered inadequate. Discontinuation rates for lifitegrast and cyclosporine, which currently comprise standard of care, exceed 60% within 12 months of initiation of therapy, in part due to delayed onset of effect.


“The potential for patients to experience acute symptomatic relief and observe rapid improvement in ocular redness after the initiation of therapy represents a new possible paradigm in dry eye disease treatment and could offer significant clinical advantage over existing therapies, which often require weeks of drug administration before patients experience even moderate improvement,” stated Victor Perez, M.D., Professor of Ophthalmology at Duke University School of Medicine and a member of Aldeyra’s Anterior Segment Scientific Advisory Board.


The main cohort of TRANQUILITY is expected to begin enrollment in February 2021, following completion of tear RASP analysis from the run-in cohort and confirmation of endpoints and number of subjects. Results from TRANQUILITY are expected in the second half of 2021. A second Phase 3 clinical trial, TRANQUILITY-2, is expected to initiate in the first quarter of 2021.
