LEXINGTON, Mass.--(BUSINESS WIRE)-- Aldeyra Therapeutics (Nasdaq: ALDX) (Aldeyra or the Company), a biotechnology company developing novel immune-modulating therapies to treat ocular and systemic diseases, today announced completion of enrollment in the Phase 3 TRANQUILITY Trial of 0.25% reproxalap ophthalmic solution (reproxalap) for the treatment of patients with dry eye disease.

“Following the recent announcement of top-line results from our Phase 2 clinical trial, which achieved the primary endpoint of ocular redness and which we intend to submit as a pivotal trial, completion of enrollment in TRANQUILITY is a significant milestone as we advance reproxalap toward an anticipated NDA submission early next year for the treatment of dry eye disease,” stated Todd C. Brady, M.D., Ph.D., President and CEO of Aldeyra. “If the primary endpoint of ocular redness in TRANQUILITY is achieved, and in conjunction with two previously announced clinical trials demonstrating improvement in ocular dryness symptoms, we believe that the efficacy requirements for NDA submission will have been met.”

The multi-center, double-masked, parallel-group TRANQUILITY Trial enrolled 300 patients randomized equally to receive either reproxalap or vehicle. 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. The primary endpoint of the TRANQUILITY Trial is ocular redness. Top-line results from the trial are expected this quarter.

Based on the results of the recently completed Phase 2 clinical trial, which enrolled 158 patients and achieved statistical significance in the primary endpoint of ocular redness, TRANQUILITY is at least 90% powered to detect a statistically significant difference in ocular redness. TRANQUILITY is one of two identically designed Phase 3 clinical trials Aldeyra is conducting in patients with dry eye disease. Enrollment in the second trial, TRANQUILITY-2, is ongoing. If successful, either TRANQUILITY or TRANQUILITY-2 could complete 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. For satisfaction of symptom efficacy requirements, Aldeyra intends to submit two previously completed adequate and well-controlled symptom trials that pre-specified patient-reported ocular dryness score as a primary endpoint, the RENEW-Part 1 Trial and the Formulation Phase 2 clinical trial. For satisfaction of the sign efficacy requirements, Aldeyra intends to submit the recently completed Phase 2 clinical trial and, if positive, either TRANQUILITY or TRANQUILITY-2, all of which pre-specify ocular redness as a primary endpoint.

“With its safety and efficacy profile—demonstrated in clinical trials encompassing more than 1,300 patients in aggregate—reproxalap has the potential to provide relief to the estimated 34 million adults in the U.S. who suffer from persistently disturbing symptoms and ocular redness caused by dry eye disease,” Dr. Brady stated.

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 Aldeyra Therapeutics, Inc.

Aldeyra Therapeutics, Inc. is a biotechnology company developing novel immune-modulating therapies to treat ocular and systemic diseases. Two of the Company’s lead product candidates, reproxalap and ADX-629, target RASP, which are pre-cytokine, systems-based mediators of inflammation. 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 (methotrexate for intravitreal injection), a drug candidate in Phase 3 testing for the prevention of proliferative vitreoretinopathy.
