Aldeyra Therapeutics Announces Second-Quarter 2020 Financial Results and Provides Corporate Update

Aldeyra Therapeutics, Inc. (Nasdaq: ALDX) (Aldeyra), a clinical-stage biotechnology company focused on the development of novel therapies with the potential to improve the lives of patients with immune-mediated diseases, today announced financial results for the second quarter of 2020 and provided a corporate update.

“We continue to make important progress in advancing a number of clinical-stage programs focused on the development of reproxalap and ADX-629, our first-in-class reactive aldehyde species (RASP) inhibitors,” stated Todd C. Brady, M.D., Ph.D., President and CEO of Aldeyra. “Following a successful meeting with the US Food and Drug Administration (FDA) in June, we are on track to initiate clinical trials assessing levels of RASP, a pro-inflammatory mediator, in the tears of patients with dry eye disease. Clinical development of ADX-629, an orally available RASP inhibitor, in COVID-19, psoriasis, and atopic asthma is expected to begin during the second half of this year.”

“We also have enhanced our financial flexibility with recent common stock sales to Perceptive Advisors and Avidity Partners, transactions that generated gross proceeds of approximately $19.5 million and completed our previously announced at-the-market offering program,” Dr. Brady continued. “We now expect to be able to fund operations through 2022, including potential approvals for reproxalap in dry eye disease and allergic conjunctivitis.”

Recent Highlights

• Use of RASP as an Objective Sign for Treatment of Dry Eye Disease: In June 2020, Aldeyra announced agreement with the FDA for the use of RASP as an objective sign for the treatment of dry eye disease, marking the first new objective sign for the disease in more than a decade.

• IND Submission for ADX-629: Aldeyra completed an Investigational New Drug (IND) submission under the FDA’s Coronavirus Accelerated Treatment Program to initiate a Phase 2 clinical trial of ADX-629 in patients with COVID-19.

• Orphan Medicinal Product Designation for ADX-2191: The European Commission designated ADX-2191 as an orphan medicinal product for the treatment of retinal detachment. ADX-2191, a novel and proprietary intravitreal formulation of methotrexate, is being evaluated in the Phase 3 GUARD Trial for prevention of recurrent retinal detachment due to proliferative vitreoretinopathy (PVR), the leading cause of failure of retinal detachment surgery. Drugs that receive the orphan medicinal product designation in the European Union (EU) are entitled to protocol assistance, research funding, and, upon approval, 10 years of EU market exclusivity.

Clinical-Stage Pipeline Updates

• Reproxalap – A Novel Topical Ocular RASP Inhibitor for the Treatment of Dry Eye Disease and Allergic Conjunctivitis: In the fourth quarter of this year, Aldeyra intends to initiate clinical testing to assess the activity of topical ocular reproxalap in reducing tear levels of RASP and other objective signs of dry eye disease, subject to finalization of trial design, RASP assay development, and potential disruptions due to the COVID-19 pandemic. In addition, a safety trial in dry eye disease patients is expected to be initiated in the fourth quarter of 2020. NDA submission is expected by the end of 2021, assuming positive clinical trial results and regulatory review. Top-line results from the Phase 3 INVIGORATE allergen chamber trial, the second Phase 3 trial of reproxalap in allergic conjunctivitis, are expected in the first half of 2021.

• ADX-629–A Novel Orally Available RASP Inhibitor for the Treatment of Systemic Inflammatory Diseases: An IND for Phase 2 clinical testing of ADX-629 in patients with COVID-19 has been filed with the FDA. Additionally, in the fourth quarter of this year, the company expects to initiate Phase 2a clinical trials of ADX-629 in patients with psoriasis and atopic asthma.

• ADX-2191 – An Intravitreal Methotrexate Injectable for Rare Proliferative Ocular Diseases: Aldeyra has filed for Orphan Drug Designation (ODD) with the FDA for ADX-2191 for the treatment of primary vitreoretinal lymphoma, a rare, aggressive, high-grade cancer that arises in the vitreous and retina. Additionally, an update on enrollment in the Phase 3 GUARD trial of ADX-2191 for the prevention of PVR, a rare but serious sight-threatening retinal disease with no approved treatment, is expected by the end of this year.

• ADX-1612–A Protein Chaperome Inhibitor for Systemic Disease: Enrollment has been completed in the investigator-sponsored Phase 2 EUDARIO Trial of ADX-1612 in ovarian cancer. Regarding the ADX-1612 COVID-19 program, consistent with FDA feedback, additional preclinical antiviral testing of ADX-1612 against SARS-CoV-2, the virus that causes COVID-19, will be performed by the National Institute of Allergy and Infectious Diseases, which has accepted the company’s request to evaluate ADX-1612 in in vivo models. Aldeyra expects to provide an update on the ADX-1612 COVID-19 program by the end of 2020.

Financial Results for the Quarter Ended June 30, 2020

For the quarter ended June 30, 2020, Aldeyra reported a net loss of $7.5 million, compared with a net loss of $13.3 million for the quarter ended June 30, 2019. Net loss per share was $0.25 for the quarter ended June 30, 2020, compared with $0.49 for the same period in 2019. Losses have resulted from the costs of Aldeyra's clinical trials and research and development programs, as well as from general and administrative expenses.

Research and development expenses were $4.9 million for the quarter ended June 30, 2020, compared with $10.7 million for the same period in 2019. The decrease of $5.8 million is primarily related to the decreases in clinical and preclinical development, manufacturing, and personnel costs.

General and administrative expenses were $2.2 million for the quarter ended June 30, 2020, compared with $3.1 million for the same period in 2019. The decrease of $0.9 million is due to decreases in personnel related costs, including stock-based compensation, and other miscellaneous administrative costs.

For the quarter ended June 30, 2020, total operating expenses were $7.1 million, compared with total operating expenses of $13.7 million for the same period in 2019.

As of June 30, 2020, cash, cash equivalents, and marketable securities were $66.2 million. Subsequent to June 30, 2020, $25.2 million in cash was received from at-the-market offering program sales to Perceptive Advisors, Avidity Partners, and other investors. Based on current operating plans, cash, cash equivalents, and marketable securities as of June 30, 2020, plus the additional at-the-market offering program proceeds, are expected to be sufficient to fund operations through the end of 2022, including potential NDA approvals for reproxalap in dry eye disease and allergic conjunctivitis, assuming positive clinical trial results, and planned NDA submissions, acceptances, and approvals. Use of Aldeyra’s cash, cash equivalents, and marketable securities are also expected to include the continuation of Part 1 of the Phase 3 GUARD Trial in PVR, and Phase 2 clinical testing of ADX-629, an orally administered RASP inhibitor, in inflammatory diseases.
