Aldeyra Therapeutics Achieves Primary Endpoints in Dry Eye Disease Chamber Crossover Clinical Trial
Reproxalap Statistically Superior to Vehicle for Both Primary Endpoints of Ocular Redness (P=0.0004) and
Schirmer Test≥10mm Responder Analysis Multiplicity-Controlled Secondary Endpoint Achieved (P=0.0361)
- Secondary Endpoints Achieved for All Symptoms Assessed: Dryness (P=0.0068), Discomfort (P<0.0001), Grittiness (P=0.0001), Stinging (P=0.0001), Burning (P<0.0001), and Itching (P=0.0003)

“Statistical significance in favor of reproxalap over vehicle for all three dry eye disease signs that we intend to submit to a New Drug Application, in addition to observed rapid symptomatic improvement, favorably positions reproxalap, if approved for sale, as a potentially differentiated therapeutic option for the treatment of dry eye disease,” stated
Relative to vehicle, statistically significant reduction in ocular redness was observed following treatment with reproxalap as soon as 10 minutes after dry eye chamber entry, which was the first time point assessed, and over the majority of chamber assessment time points, including the final time point 90 minutes after chamber entry. Schirmer test, which was assessed approximately 10 minutes before and after the fourth dose of reproxalap or vehicle, was statistically significant in favor of reproxalap at both time points, indicating the potential activity of prior dosing as well as additional activity of the fourth dose over a single day of drug administration. The Schirmer test ≥10 mm responder analysis has been reported to correlate with symptomatic improvement in dry eye disease,1 and achievement of the responder endpoint is consistent with the symptomatic improvement observed in the crossover clinical trial: reproxalap was statistically lower than vehicle for the secondary endpoints of ocular dryness (P=0.0068), discomfort (P<0.0001), grittiness (P=0.0001), stinging (P=0.0001), burning (P<0.0001), and itching (P=0.0003) symptoms.
No safety signals were observed in the trial, and reproxalap was well tolerated; there were no treatment-emergent moderate or serious adverse events. Three patients discontinued due to adverse events, two during vehicle administration and one during reproxalap administration. Reproxalap has now been studied in over 1,800 patients. The most common reported adverse event in clinical trials is mild and transient instillation site discomfort.
Pending discussion with the
“With another set of positive clinical results showing improvement in both the signs and symptoms of dry eye disease, I believe that reproxalap is an eagerly anticipated advancement for our patients suffering from dry eye disease because available therapies are often inadequate,” stated
Conference Call Information
Aldeyra will host a conference call to discuss this announcement at
After the live webcast, the event will remain archived on the Aldeyra website for 90 days.
Reproxalap is an investigational first-in-class small-molecule modulator of RASP (reactive aldehyde species), which are elevated in ocular and systemic inflammatory disease. Reproxalap’s unique mechanism of action has been supported by the demonstration of statistically significant and clinically relevant activity in multiple physiologically distinct late-phase clinical indications.
About Dry Eye Disease
Dry eye disease is a common inflammatory disease estimated to affect 39 million or more adults in
Aldeyra develops innovative therapies designed to treat immune-mediated diseases. Our approach is to discover pharmaceuticals that modulate immunological systems, instead of directly inhibiting or activating single protein targets, with the goal of optimizing multiple pathways at once while minimizing toxicity. Two of our lead product candidates, reproxalap and ADX-629, target pre-cytokine, systems-based mediators of inflammation known as RASP (reactive aldehyde species). Reproxalap is in late-stage clinical trials in patients with dry eye disease and allergic conjunctivitis. ADX-629, an orally administered RASP modulator, is in Phase 2 clinical testing for the treatment of systemic immune-mediated diseases. Our pipeline also includes ADX-2191 (intravitreal methotrexate 0.8%), in development for the prevention of proliferative vitreoretinopathy and the treatment of retinitis pigmentosa and primary vitreoretinal lymphoma.
