Press Release Details

LEXINGTON, MA -- (Marketwired) -- 06/07/16 -- Aldeyra Therapeutics, Inc. (NASDAQ: ALDX) (Aldeyra), a biotechnology company focused on the development of products to treat diseases related to aldehydes, today announced that the last patient has completed dosing in Aldeyra's randomized, parallel-group, double-masked, vehicle-controlled Phase II clinical trial of topical NS2, a novel aldehyde trap, for the treatment of the dermatologic manifestations of Sjögren-Larsson Syndrome (SLS). Patients with SLS, a rare inborn error of aldehyde metabolism, suffer from a severe skin disease called ichthyosis, which represents a significant daily challenge for patients and caregivers. 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.

Todd C. Brady, M.D., Ph.D., President and CEO of Aldeyra, commented, "We are excited to complete enrollment and dosing of patients in our SLS Phase II trial. Sjögren-Larsson Syndrome is rare, but the dermatologic manifestations of the disease are debilitating and there are no therapies approved by the U.S. Food and Drug Administration. We look forward to providing data from the trial in the third quarter of this year."

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 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 Aldeyra Therapeutics, Inc.

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.
