Aldeyra Therapeutics Announces Second Quarter 2016

LEXINGTON, MA--(Marketwired - Aug 10, 2016) - Aldeyra Therapeutics, Inc. ( NASDAQ : ALDX ) (Aldeyra), a biotechnology company focused on the development of products to treat diseases related to aldehydes, today reported second quarter financial results and provided a corporate update.

"We are extremely pleased with our progress through the first half of the year with our novel aldehyde trap, NS2," said Todd C. Brady, M.D., Ph.D., President and CEO of Aldeyra. "In February, we reported positive Phase II clinical trial results in allergic conjunctivitis, and in May, we reported positive Phase II clinical trial results in noninfectious anterior uveitis. Yesterday, we announced positive results from our randomized, double-blind, vehicle controlled clinical trial in patients with Sjögren-Larsson Syndrome, a rare inborn error of metabolism with no FDA-approved therapy."

Dr. Brady continued, "In aggregate, the clinical trial results this year validate NS2 and the aldehyde trap platform as a potentially important therapeutic approach in inflammation and inborn errors of aldehyde metabolism. We look forward to continuing the development of NS2 in these and other clinical indications with unmet medical need."

Recent Highlights

• Reported positive results from a randomized, double-blind, vehicle controlled clinical trial in patients with Sjögren-Larsson Syndrome.  Aldeyra recently reported positive data from a randomized, parallel-group, double-blind, vehicle-controlled, multi-center clinical trial of topical NS2 for the treatment of the dermatologic manifestations of Sjögren-Larsson Syndrome (SLS). Patients with SLS, a rare inborn error of aldehyde metabolism, suffer from ichthyosis, a debilitating dermatologic disease characterized by dry, thickened, scaly skin. The symptoms of SLS are thought to be related to high levels of toxic fatty aldehydes due to genetic mutations in fatty aldehyde dehydrogenase, an enzyme critical for the normal function of skin and other organs. NS2 is specifically designed to reduce levels of toxic aldehydes, and is the first therapy to be directed at the putative cause of SLS. In the clinical trial, NS2 consistently produced clinically meaningful effects in reducing the severity of ichthyosis that exceeded vehicle response.

• Reported positive results from Phase II clinical trial in patients with noninfectious anterior uveitis.  In May 2016, Aldeyra reported positive data from a randomized, parallel-group, multi-center, investigator-masked, active-controlled Phase II clinical trial in subjects with noninfectious anterior uveitis. Forty-five patients were randomized to receive either NS2 or Pred-Forte®, a standard-of-care corticosteroid that leads to elevations of intraocular pressure in some patients, or a combination of NS2 and Pred-Forte®. Results from this study demonstrated that NS2 was as clinically effective as Pred-Forte but did not increase intraocular pressure.

• Reported positive results from Phase II clinical trial in subjects with allergic conjunctivitis. In February 2016, Aldeyra reported that the results of a randomized, parallel-group, single-center, double-masked, vehicle-controlled Phase II clinical trial of topical ocular NS2 in subjects with induced allergic conjunctivitis demonstrated statistically significant and sustained activity of NS2 over vehicle in reducing ocular itching and tearing.

Second Quarter 2016 Financial Review

For the quarter ended June 30, 2016, Aldeyra reported a net loss of approximately $4.3 million compared to a net loss of approximately $2.2 million for the quarter ended June 30, 2015. Basic and diluted net loss per share was $0.41 for the quarter ended June 30, 2016 compared to basic and diluted net loss of $0.27 per share for the quarter ended June 30, 2015. 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 approximately $2.8 million for the quarter ended June 30, 2016 compared to approximately $1.2 million for the quarter ended June 30, 2015. The increase of approximately $1.6 million is primarily related to the increase in Aldeyra's external research and development expenditures, including preclinical, manufacturing and clinical development activities and an increase in personnel costs, including stock-based compensation due to an increase in headcount.

General and administrative expenses were approximately $1.5 million for the quarter ended June 30, 2016, compared to approximately $955,000 for the quarter ended June 30, 2015. The increase of approximately $507,000 was primarily related to an increase in insurance costs, legal costs and personnel costs, including stock-based compensation due to an increase in headcount.

During the quarter, Aldeyra sold in an underwritten public offering 2,760,000 shares of its common stock, including 360,000 shares sold in connection with the exercise in full by the underwriter of its option to purchase additional shares. The net proceeds of the offering, including the full exercise of the option, were approximately $12.6 million, after deducting the underwriting discounts and commissions and the other estimated offering expenses payable by Aldeyra.

Cash, cash equivalents and marketable securities were approximately $32.5 million at June 30, 2016.

About Aldeyra Therapeutics Aldeyra Therapeutics, Inc. is a biotechnology company devoted to improving lives by inventing, developing and commercializing products that treat diseases thought to be related to endogenous aldehydes, a naturally occurring class of pro-inflammatory and toxic molecules. Aldeyra's lead product candidate, NS2, is an aldehyde trap in development for ocular inflammation, as well as for Sjögren-Larsson Syndrome and Succinic Semi-Aldehyde Dehydrogenase Deficiency, two inborn errors of aldehyde metabolism. NS2 has not been approved for sale in the U.S. or elsewhere.

About NS2 NS2 is an aldehyde-binding small molecule based on an innovative platform technology focused on trapping aldehydes, which are toxic and pro-inflammatory mediators of numerous diseases. By decreasing aldehyde load, NS2 may mitigate excessive inflammation and address diseases where aldehyde metabolism is impaired, including certain inborn errors of metabolism.

About Sjögren-Larsson Syndrome Sjögren-Larsson Syndrome is a rare inborn error of aldehyde metabolism caused by mutations in fatty acid aldehyde dehydrogenase, leading to elevated toxic fatty aldehyde levels that are thought to contribute to severe ichthyosis (scaly, thickened, dry skin), neurological disorders, and retinal disease. There is no therapy for SLS that has been approved by the U.S. Food and Drug Administration.

About Noninfectious Anterior Uveitis Noninfectious anterior uveitis is a rare, potentially blinding disease that may be mediated in part by pro-inflammatory aldehydes, and is characterized by inflammation in the front of the eye, pain, impaired vision, and photophobia.

About Allergic Conjunctivitis Allergic conjunctivitis is a common allergic disease that is thought to be mediated in part by pro-inflammatory aldehydes, and is characterized by inflammation of the conjunctiva (a membrane covering part of the front of the eye), resulting in ocular itching, excessive tear production, lid swelling and redness.
