Aldeyra Therapeutics Announces Completion of Enrollment in Phase 3 TRANQUILITY-2 Trial in Patients with Dry Eye Disease

Rhea-AI Summary

Aldeyra Therapeutics, Inc. (NASDAQ: ALDX) announced the completion of enrollment in the Phase 3 TRANQUILITY-2 Trial for its investigational drug, reproxalap, aimed at treating dry eye disease. The multi-center study enrolled 361 patients and measured tear volume and ocular redness as primary endpoints. Top-line results are expected this quarter, and if successful, the data could support a New Drug Application (NDA) submission. Aldeyra plans to utilize data from completed clinical trials to meet FDA regulatory requirements.

Positive

• Completion of enrollment in TRANQUILITY-2 Trial with 361 patients increasing clinical data robustness.
• Top-line results expected this quarter, potentially providing key data for NDA submission.
• Previous Phase 2 trial achieved primary endpoint of ocular redness, supporting efficacy claims.

Negative

• Dependence on upcoming trial results to meet NDA submission requirements introduces regulatory uncertainty.
• Final outcomes of TRANQUILITY-2 are still pending, creating market speculation.

Top-Line Results from TRANQUILITY-2 Expected in the Second Quarter of 2022

LEXINGTON, Mass.--(BUSINESS WIRE)-- Aldeyra Therapeutics, Inc. (Nasdaq: ALDX) (Aldeyra), a biotechnology company discovering and developing innovative therapies for the treatment of immune-mediated diseases, today announced completion of enrollment in the Phase 3 TRANQUILITY-2 Trial of 0.25% reproxalap ophthalmic solution (reproxalap) in patients with dry eye disease.

The multi-center, double-masked, parallel-group TRANQUILITY-2 Trial enrolled 361 patients randomized to receive either reproxalap or vehicle over two days. On the first day, patients received four doses, and Schirmer testing (a measure of tear volume) was performed before and after the fourth dose. On the second day, doses were administered just prior to and at the mid-point of a 90-minute dry eye chamber with minimal humidity, high airflow, and forced visual tasking. The primary endpoints of the TRANQUILITY-2 Trial are Schirmer test on the first day of dosing and ocular redness on the second day of dosing during the dry eye chamber. Top-line results from the trial are expected to be announced this quarter.

Based on the results of the previously completed Phase 2 and TRANQUILITY clinical trials, TRANQUILITY-2 is at least 90% powered to detect a statistically significant difference in Schirmer test or ocular redness endpoints. If successful in meeting one of the primary endpoints, TRANQUILITY-2 could complete New Drug Application (NDA) submission requirements for demonstration of improvement in an objective sign of dry eye disease.

Per draft U.S. Food and Drug Administration (FDA) guidance, to be considered for regulatory approval in the United States, a product candidate for the treatment of dry eye disease must demonstrate efficacy in an objective sign in at least two clinical trials and efficacy in a subjective symptom in at least two clinical trials. To satisfy the symptom efficacy requirements, Aldeyra intends to submit two previously completed 12-week adequate and well-controlled symptom trials that pre-specified patient-reported ocular dryness score as a primary endpoint, the Phase 3 RENEW-Part 1 Trial and the Formulation Phase 2 clinical trial.

Aldeyra’s previously announced Phase 2 clinical trial achieved the primary endpoint of ocular redness, an approvable sign of dry eye disease. Pending discussion with the FDA and the results of TRANQUILITY-2, Aldeyra may submit two pivotal trials for either ocular redness (Phase 2 and TRANQUILITY-2) or Schirmer test (TRANQUILITY and TRANQUILITY-2), or two trials for both signs (Phase 2, TRANQUILITY, and TRANQUILITY-2) if ocular redness and Schirmer test are achieved in TRANQUILITY-2. Either Phase 2 or Phase 3 clinical trials can be submitted as pivotal, provided that the trials are adequate and well-controlled.

Pending enrollment of the ongoing 12-month safety trial of reproxalap in dry eye disease patients and the outcome of TRANQUILITY-2, Aldeyra’s dry eye disease NDA submission is expected to occur mid-2022.

About Reproxalap

Reproxalap, an investigational new drug, is a first-in-class small-molecule modulator of RASP (reactive aldehyde species), which are elevated in ocular and systemic inflammatory disease. Reproxalap’s mechanism of action has been supported by 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 of the largest markets in ophthalmology.

About Aldeyra

Aldeyra Therapeutics discovers and develops innovative therapies designed to treat immune-mediated diseases. Our approach is to develop therapies 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 Phase 3 clinical trials in patients with dry eye disease and allergic conjunctivitis. ADX-629, an orally administered RASP modulator, is in Phase 2 clinical testing. 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.
