LEXINGTON, Mass.--(BUSINESS WIRE)--Aldeyra Therapeutics, Inc. (Nasdaq: ALDX) (Aldeyra), a biotechnology company developing novel immune-modulating therapies to treat ocular and systemic diseases, today reported recent corporate highlights and financial results for the quarter ended September 30, 2021.

“We continue to make important progress in developing safe and effective treatments for ocular and systemic diseases to improve the lives of patients who have significant unmet medical needs,” stated Todd C. Brady, M.D., Ph.D., President and Chief Executive Officer of Aldeyra. “Among key clinical milestones, we expect to release top-line results from the Phase 3 TRANQUILITY and TRANQUILITY-2 dry eye disease clinical trials in the fourth quarter of this year and are on track to report top-line results from Phase 2 clinical trials of ADX-629 in psoriasis, atopic asthma, and COVID-19 by the end of the year or early 2022. We also look forward to the planned initiation of our Phase 2 clinical trial of ADX-2191 in retinitis pigmentosa this quarter.”

Recent Corporate Highlights and Program Updates

• Top-Line Results from the Phase 3 TRANQUILITY and TRANQUILITY-2 Trials in Dry Eye Disease Expected in the Fourth Quarter of 2021. Ocular redness is the primary endpoint of the TRANQUILITY trials, which include tear RASP levels, Schirmer's test, and dry eye disease symptoms as secondary endpoints. In addition, enrollment has completed in a multi-center, double-masked, randomized, vehicle-controlled, parallel-group Phase 2 clinical trial of reproxalap in dry eye disease. The Phase 2 trial was designed to optimize the measurement of tear RASP levels.
• Phase 2 Clinical Trial of ADX-2191 in Retinitis Pigmentosa Scheduled to Initiate in the Fourth Quarter of 2021. The primary endpoint of the trial is the safety and tolerability of ADX-2191 in patients with retinitis pigmentosa. Secondary endpoints are visual acuity, central retinal sensitivity, dark-adapted retinal sensitivity, and retinal morphometry.
• Phase 2 Clinical Trial Results from ADX-629, an Orally Administered RASP Inhibitor, Expected in the Fourth Quarter of 2021 or First Quarter of 2022. ADX-629 is in proof-of-concept Phase 2 clinical trials for the treatment of psoriasis, atopic asthma, and COVID-19. ADX-629 represents a first-in-class systems-based therapeutic approach for the potential treatment of many immune-mediated diseases that today are treated with single-target drugs that can lead to toxicity.
• Post-Acute Ocular Tolerability Comparison of Topical Reproxalap 0.25% and Lifitegrast 5% in Patients with Dry Eye Disease Paper Published in Peer-Reviewed Journal. Clinical Ophthalmology published the results of a clinical trial comparing the subjective eye drop experience of patients with dry eye disease over one hour after a single dose of two formulations of reproxalap versus lifitegrast.

Third-Quarter 2021 Financial Results

Cash and cash equivalents as of September 30, 2021 were $241.4 million. Based on Aldeyra’s current operating plan, the company believes that existing cash and cash equivalents will be sufficient to fund currently projected operating expenses through the end of 2023, including potential New Drug Application submissions; initial commercialization of reproxalap, if approved; and continued development of the company’s product candidates in ocular and systemic immune-mediated diseases.

For the quarter ended September 30, 2021, Aldeyra reported a net loss of $15.8 million, compared with a net loss of $8.9 million for the quarter ended September 30, 2020. Net loss per share was $0.27 for the quarter ended September 30, 2021, compared with $0.23 for the same period in 2020. Losses have resulted from the costs of clinical trials and research and development programs, as well as from general and administrative expenses.

Research and development expenses were $12.9 million for the quarter ended September 30, 2021, compared with $6.1 million for the same period in 2020. The increase of $6.8 million is primarily related to increases in our clinical research and development expenditures and consulting costs, partially offset by decreases in personnel related costs, including stock-based compensation, and manufacturing activities.

General and administrative expenses were $2.5 million for the quarter ended September 30, 2021, compared with $2.3 million for the quarter ended September 30, 2020. The increase of $0.2 million is primarily due to an increase in miscellaneous administrative costs.

For the quarter ended September 30, 2021, total operating expenses were $15.4 million, compared with total operating expenses of $8.4 million for the same period in 2020.
