Aldeyra Therapeutics Achieves Statistical Significance for Primary Endpoint and All Secondary Endpoints in Phase 3 INVIGORATE Clinical Trial of Reproxalap in Allergic Conjunctivitis
- Statistical Significance Achieved for Primary Endpoint of Ocular Itching at All Prespecified Timepoints (p<0.0001)
- Statistical Significance Achieved for Key Secondary Endpoint of Ocular Redness (p<0.0001)
- Statistical Significance Achieved for Secondary Endpoints of Ocular Tearing (p<0.0001) and Total Ocular Severity Score (p<0.0001)
- Results Consistent with Phase 3 ALLEVIATE Allergic Conjunctivitis Clinical Trial and Previous Chamber Results in Phase 2 Allergic Conjunctivitis Trial and Run-In Cohort of Phase 3 TRANQUILITY Dry Eye Disease Trial
- Reproxalap Potentially Represents the First New Allergic Conjunctivitis Therapeutic Mechanism in Decades

“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
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
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.

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.
