Forward-looking statements include all statements that are not historical facts and, in some cases, can be identified by terms such as “may,” “might,” “will,” “objective,” “intend,” “should,” “could,” “can,” “would,” “expect,” “believe,” “anticipate,” “project,” “target,” “design,” “estimate,” “predict,” “potential,” “plan” or similar expressions and the negatives of those terms. Forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause Aldeyra’s actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. These statements reflect Aldeyra’s current views with respect to future events and are based on assumptions and subject to risks and uncertainties, including the development, clinical and regulatory plans or expectations for Aldeyra’s product candidates and Aldeyra’s continuing review and quality control analysis of clinical data. Important factors that could cause actual results to differ materially from those reflected in Aldeyra's forward-looking statements are described in Aldeyra’s most recent Annual Report on Form 10-K and Quarterly Report on Form 10-Q, as well as Aldeyra’s subsequent filings with the Securities and Exchange Commission. All of Aldeyra's development timelines may be subject to adjustment depending on recruitment rate, regulatory review, preclinical and clinical results, and other factors that could delay the initiation, completion, or reporting of clinical trials. In addition to the risks described above and in Aldeyra's other filings with the SEC, other unknown or unpredictable factors also could affect Aldeyra's results. No forward-looking statements can be guaranteed and actual results may differ materially from such statements. The information in this presentation is provided only as of June 25, 2019, and Aldeyra undertakes no obligation to update any forward-looking statements contained in this presentation on account of new information, future events, or otherwise, except as required by law.

No statistically significant difference was observed between the reproxalap group and the vehicle control group on the primary (time to cure) or secondary endpoints, due to high rates of disease resolution in vehicle-treated patients. For the primary and all time-to-event secondary endpoints, reproxalap was numerically favored over vehicle. The ocular inflammation improvement in the reproxalap group was consistent with Phase 2 trial results, which were statistically noninferior to corticosteroid therapy. Reproxalap activity in reducing ocular inflammation in patients with moderate disease, a pre-specified subgroup, was statistically superior to that of vehicle. Topical ocular reproxalap was observed to be safe and well tolerated, consistent with prior clinical trials. Aldeyra intends to discontinue the noninfectious anterior uveitis program in order to prioritize high-value Phase 3 ocular programs in dry eye disease, allergic conjunctivitis, and proliferative vitreoretinopathy.

Exhibit 99.2

Aldeyra Therapeutics Announces Results from the SOLACE Trial in Noninfectious Anterior Uveitis

• Statistical Significance Not Achieved for Primary or Secondary Endpoints Due to High Rates of Disease Resolution in Vehicle-Treated Patients, but Activity of Reproxalap Observed to be Consistently Greater than Vehicle

• Noninfectious Anterior Uveitis Program to be Discontinued

• Company Plans to Prioritize Phase 3 Ocular Pipeline Programs in Dry Eye Disease, Allergic Conjunctivitis, and Proliferative Vitreoretinopathy

LEXINGTON, Mass., June 25, 2019 /BUSINESS WIRE/ — Aldeyra Therapeutics, Inc. (Nasdaq: ALDX) (Aldeyra), a biotechnology company devoted to developing and commercializing next-generation medicines to improve the lives of patients with immune-mediated diseases, today announced results from the noninfectious anterior uveitis SOLACE Trial. Statistical significance was not achieved for the primary or secondary endpoints, due to high rates of disease resolution in vehicle-treated patients, but activity of reproxalap was consistently greater than that of vehicle.

“The results of the SOLACE Trial confirm the potential of reproxalap to treat ocular inflammation, and further validate the novel mechanism of action of reproxalap, which demonstrated highly statistically significant immune-modulating activity in the Phase 3 ALLEVIATE Trial and Phase 2b Dry Eye Disease trial,” stated Todd C. Brady, M.D., Ph.D., President and Chief Executive Officer of Aldeyra. “We look forward to aggressively prioritizing advancement of high-value ocular programs in dry eye disease, allergic conjunctivitis, and proliferative vitreoretinopathy.”

Topical ocular reproxalap was observed to be safe and well-tolerated. Reproxalap ophthalmic solution, in various concentrations, has now been administered to over 800 patients in nine clinical trials for ocular inflammation.
