Press Release Details

LEXINGTON, Mass., Nov. 29, 2017 /PRNewswire/ -- Aldeyra Therapeutics, Inc. (NASDAQ: ALDX) ("Aldeyra"), a clinical-stage biotechnology company devoted to treating inflammation, inborn errors of metabolism, and other diseases related to endogenous aldehyde toxicity, presented new statistical analyses of the results of a randomized, multi-center, investigator-masked, comparator-controlled, parallel-group Phase 2 clinical trial of topical ocular reproxalap (formerly known as ADX-102), a first-in-class aldehyde sequestering agent, to the American Uveitis Society held at the American Academy of Ophthalmology 2017 Annual Meeting. The results of the analyses demonstrated formal statistical non-inferiority (p=0.036 after two weeks of therapy, p=0.048 after four weeks of therapy) of 0.5% reproxalap ophthalmic solution to Pred Forte®, a topical ocular corticosteroid, in reducing anterior chamber inflammatory cell count, the standard noninfectious anterior uveitis clinical endpoint. The combination of reproxalap and low-frequency (twice-daily) Pred Forte® administration was also statistically non-inferior to Pred Forte® monotherapy (four-times-daily). Dr. John Sheppard, an internationally recognized expert in ocular inflammation, gave the presentation, which is available on the investor relations page of the Aldeyra Therapeutics corporate website at ir.aldeyra.com.

"The use of corticosteroid therapy for the treatment of ocular inflammation is hampered by ophthalmic toxicity, including cataract formation, secondary infection, viral reactivation, delayed wound healing and elevated intraocular pressure that can cause irreversible glaucomatous optic atrophy," commented Dr. Sheppard.  "Reproxalap could represent a welcome addition to the topical therapeutic options available to practitioners who treat noninfectious anterior uveitis, a severe inflammatory disease which can lead to permanent vision loss."

In April 2017, Aldeyra announced the initiation of a Phase 3 clinical trial of topical reproxalap in patients with noninfectious anterior uveitis. The Phase 3 trial is expected to enroll up to 100 patients with active disease, randomized equally to receive either 0.5% topical ocular reproxalap or vehicle for four weeks.  Consistent with prior clinical trials used for marketing registration, the primary endpoint will be the resolution of anterior chamber cellular inflammation. Results of the trial are expected to be announced in the second half of 2018.

Pro-inflammatory aldehyde mediators are a novel target in the treatment of inflammation. The positive clinical results reported for reproxalap from Phase 2 clinical trials in dry eye disease, allergic conjunctivitis, and noninfectious anterior uveitis suggest that aldehyde sequestration could also be effective for the treatment of inflammatory diseases that affect other parts of the body, including systemic inflammatory and autoimmune conditions that afflict millions of patients worldwide. 

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, reproxalap (formerly known as ADX-102) is a small molecule aldehyde sequestering agent in Phase 2b clinical development for the treatment of dry eye disease, and Phase 3 clinical development for the treatment of allergic conjunctivitis, noninfectious anterior uveitis, and Sjögren-Larsson Syndrome. Reproxalap has not been approved for sale in the U.S. or elsewhere.

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. Topical corticosteroid therapy is the only approved therapy for the resolution of inflammation associated with noninfectious anterior uveitis, but can lead to serious ocular complications, including glaucoma, infections, and cataracts.
