LEXINGTON, MA, USA I April 27, 2021 I Aldeyra Therapeutics, Inc. (Nasdaq: ALDX) (Aldeyra), a clinical-stage biotechnology company focused on the development of novel therapies with the potential to improve the lives of patients with immune-mediated diseases, today announced positive top-line results from the Phase 3 INVIGORATE Clinical Trial of 0.25% reproxalap ophthalmic solution (reproxalap), an investigational new drug, in patients with allergic conjunctivitis. The clinical trial successfully achieved statistical significance for the primary endpoint and all secondary endpoints.
“The statistically significant superiority of reproxalap over vehicle across all allergic conjunctivitis symptoms and signs assessed in INVIGORATE is remarkable, and suggests utility in one of the world’s most common ocular surface diseases,” stated Todd C. Brady, M.D., Ph.D., President and CEO of Aldeyra. “We believe the consistent activity observed across chamber models in allergic conjunctivitis and dry eye disease bodes well for the commercial positioning of reproxalap as potentially the only broadly applicable topical anterior segment immune-modulating drug that may be used for chronic treatment, if approved for marketing.”
The randomized, double-masked, vehicle-controlled, two-way crossover design allergen chamber Phase 3 INVIGORATE Trial enrolled 95 allergic conjunctivitis patients. The primary efficacy endpoint was change from baseline in subject-reported ocular itching score on a 0‑4 point scale over a majority of 11 timepoints from 110 to 210 minutes after allergen chamber entry. The key secondary endpoint was change from baseline in ocular redness on a 0‑4 point scale over the duration of the allergen chamber (approximately 3.5 hours).
Relative to patients treated with vehicle, patients treated with reproxalap reported statistically significant ocular itching score reduction over all 11 prespecified primary endpoint comparisons (p<0.0001 for each comparison) from 110 to 210 minutes in the allergen chamber. The reproxalap-treated patients demonstrated statistically significant reduction from baseline compared to vehicle (p<0.0001) for the key secondary endpoint of investigator-assessed ocular redness over the duration of the allergen chamber. Statistical significance was also achieved for the two secondary endpoints of change from baseline in patient-reported ocular tearing score on a 0‑3 point scale over the duration of the allergen chamber (p<0.0001) and change from baseline in total ocular severity score (11-point composite of the itching, redness, and tearing scores) over the duration of the allergen chamber (p<0.0001).
“Ocular allergy is a market that is ripe for innovation, and allergic conjunctivitis sufferers know it,” said Milton Hom, OD, of Canyon City Eyecare in Azusa, CA. “Exacerbated by the rise in global temperatures, seasonal pollen counts are exploding, leading to escalations in the prevalence of allergic conjunctivitis and dry eye disease that are growing unchecked. Even with the availability of treatments over the counter, many patients are using more than one prescription to manage ocular symptoms and redness. Based on my review of the INVIGORATE data, reproxalap, as one of the first new therapeutic mechanisms of action in years, would be a meaningful complement to the current treatment paradigm for moderate-to-severe allergic conjunctivitis patients.”
In the Phase 3 ALLEVIATE Trial, 0.25% reproxalap demonstrated statistically significant reductions from vehicle in patient-reported ocular itching over one hour following direct topical conjunctival allergen challenge. In Aldeyra’s Phase 2 allergen chamber trial, 0.25% reproxalap demonstrated statistically significant reductions from vehicle in patient-reported ocular itching and investigator-assessed ocular redness. In the run-in cohort of the Phase 3 TRANQUILITY Trial in dry eye disease patients, 0.25% reproxalap demonstrated statistically significant reductions from vehicle in patient-reported ocular dryness scores and investigator-assessed ocular redness in the dry eye chamber. The primary endpoint of the Phase 3 TRANQUILITY and TRANQUILITY-2 trials is ocular redness over the duration of the chamber. Results from the TRANQUILITY trials in dry eye disease are expected in the second half of 2021.
Reproxalap ophthalmic solution has now been administered to more than 1,200 patients across 14 clinical trials. Consistent with prior clinical experience with reproxalap, there were no observed safety or tolerability concerns in the INVIGORATE Trial and no observed adverse events other than mild and transient instillation site discomfort typical of many prescribed topical ophthalmic medications for anterior segment inflammation.
Aldeyra plans to meet with the U.S. Food and Drug Administration (FDA) in the second half of 2021 to discuss the INVIGORATE results and the potential submission of a New Drug Application.
Conference Call & Webcast Information

About Reproxalap
Reproxalap, an investigational new drug, is a novel small-molecule immune-modulating covalent inhibitor of RASP (reactive aldehyde species), which are elevated in ocular and systemic inflammatory disease. Reproxalap’s mechanism of action has been validated with the demonstration of statistically significant and clinically relevant activity in multiple physiologically distinct late-phase clinical indications. Reproxalap is currently in Phase 3 clinical development as a 0.25% ophthalmic solution for the treatment of dry eye disease and allergic conjunctivitis, two ocular inflammatory diseases that often occur together.
About Allergic Conjunctivitis
Allergic conjunctivitis affects more than 1 billion people worldwide,1 including more than 66 million in the U.S.2 The disease is thought to be mediated in part by reactive aldehyde species (RASP), leading to activation of intracellular inflammatory factors, including NF-κB, inflammasomes, and Scavenger Receptor A. The symptoms of allergic conjunctivitis – ocular itching and tearing – are chronic, painful, and persistent, affecting quality of life and leading to loss of work that can create a substantial economic burden for patients and their families.3 Although allergic conjunctivitis is one of the most common diseases treated by ophthalmologists and optometrists, in many cases physicians and patients report that currently available therapy is inadequate. Today, nearly one in five allergic conjunctivitis patients utilizes corticosteroids or other adjunctive therapy in addition to antihistamines.
About Aldeyra Therapeutics
Aldeyra Therapeutics is a clinical-stage biotechnology company focused on the development of novel therapies with the potential to improve the lives of patients with immune-mediated diseases. Two of the company’s lead investigational compounds, reproxalap and ADX-629, target RASP (reactive aldehyde species), which are elevated in ocular and systemic inflammatory disease and result in cytokine release via activation of a broad array of inflammatory factors, including NF-κB, inflammasomes, and Scavenger Receptor A. Reproxalap is being evaluated in Phase 3 clinical trials in patients with dry eye disease and allergic conjunctivitis. The company’s clinical pipeline also includes ADX-2191, a dihydrofolate reductase inhibitor in Phase 3 testing for proliferative vitreoretinopathy.
