Aldeyra Therapeutics Achieves Primary Endpoint in Phase 3 TRANQUILITY 2 Trial in Dry Eye Disease and Intends to Submit New Drug Application for Symptoms and Three Sign Endpoints of Dry Eye Disease

  • Reproxalap Statistically Superior to Vehicle for Both Prespecified Primary Endpoints of Schirmer Test (p=0.0001) and ≥10 mm Schirmer Test Responder Proportions (p<0.0001)
  • TRANQUILITY-2 Results May Allow for the Most Comprehensive Dry Eye Disease New Drug Application (NDA) Submission to Date
  • Pending Pre-NDA Meeting with the U.S. Food and Drug Administration (FDA), Clinical Efficacy Trials of Reproxalap Believed to Be Complete
  • Company to Host Conference Call at 8:00 a.m. ET Today

LEXINGTON, MA, USA I June 8, 2022 IAldeyra Therapeutics, Inc. (Nasdaq: ALDX) (Aldeyra) today announced the achievement of the primary endpoint in the Phase 3 TRANQUILITY-2 clinical trial (TRANQUILITY-2) of reproxalap, an investigational new drug candidate, for the treatment of dry eye disease. Reproxalap was statistically superior to vehicle for each of the two prespecified primary endpoints, Schirmer test (p=0.0001) and ≥10 mm Schirmer test responder proportions (p<0.0001) after a single day of dosing. The Schirmer test, a measure of ocular tear production, is the dry eye disease objective sign most commonly utilized for drug approval.

“Schirmer test is an accepted method for measuring tear production and has been used in clinical studies for over 20 years,” said Cathleen McCabe, M.D., a dry eye disease specialist for The Eye Associates in Sarasota, Florida and Chief Medical Officer at Eye Health America™. “I am extremely encouraged about the Schirmer test results and the other clinical sign endpoint data produced by reproxalap, highlighting the broad therapeutic benefit this therapy may bring to patients suffering from dry eye disease.”

Pending discussions with the FDA, Aldeyra intends to submit an NDA with ocular dryness symptom score, ocular redness, Schirmer test, and ≥10 mm Schirmer test responder analysis, encompassing results across five adequate and well-controlled completed clinical trials. The submission could represent the most comprehensive NDA submission in dry eye disease to date and allows for the potential of reproxalap to be the first dry eye disease drug approved with symptoms and at least two labeled objective signs. The clinical package is expected to offer unparalleled breadth across acute trials over one to two days of dosing and chronic trials over 12 weeks of dosing, as well as a combination of challenge and field-based assessments.

“Many of my dry eye disease patients complain that current treatments take too long to work, prolonging symptoms and negatively affecting quality of life,” said Jacob R. Lang, O.D., F.A.A.O., a dry eye disease specialist for Associated Eye Care in St. Paul, Minnesota. “Based on its rapid symptomatic control demonstrated across multiple clinical trials, reproxalap has the potential to be not only an important treatment option but a first-line therapy for dry eye disease.”

A Type B Pre-NDA meeting is expected to be held with the FDA in the third quarter of 2022, followed by a potential NDA submission, pending enrollment in the ongoing 12-month safety trial, and results from a dry eye chamber crossover trial. Enrollment of the crossover dry eye disease trial is substantially complete, and results are expected in the third quarter of 2022. Pending the results, the crossover trial is intended to be submitted to the NDA as a supportive trial.

“The positive results of TRANQUILITY-2 are expected to complete the most comprehensive dry eye disease NDA submission to date,” stated Todd C. Brady, M.D., Ph.D., President and CEO of Aldeyra. “I want to express my sincere gratitude to the principal investigators and more than 1,700 patients who have participated in clinical trials of reproxalap over the past five years, as well as our stockholders and other stakeholders for their continued confidence in Aldeyra. For many of the more than 39 million U.S. adults who suffer from dry eye disease, we believe the need for a rapidly acting therapy with a novel mechanism of action is significant. We are confident in the potential of reproxalap to meet that need.”

About Reproxalap

Reproxalap 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.

About Dry Eye Disease

Dry eye disease is a common inflammatory disease estimated to affect 39 million or more adults in the United States.1 The disease is characterized by insufficient moisture and lubrication in the anterior surface of the eye, leading to dryness, inflammation, pain, discomfort, irritation, diminished quality of life, and in severe cases, permanent vision impairment. Among many physicians and patients, existing therapy for dry eye disease is generally regarded as inadequate and often requires weeks or months to demonstrate activity. In patients with dry eye disease, pro-inflammatory RASP may contribute to ocular inflammation and changes in tear lipid composition.2 By diminishing RASP levels, Aldeyra’s lead RASP modulator reproxalap represents a novel and differentiated approach for the treatment of the symptoms and signs of dry eye disease.

About Aldeyra

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.
