On June 21, 2023, Aldeyra disclosed that it had received a Complete Response Letter from the U.S. Food and Drug Administration (“FDA”) regarding the Company’s New Drug Application (“NDA”) for its vitreoretinal lymphoma treatment, ADX-2191. The Company revealed that “[a]lthough no safety or manufacturing issues with ADX-2191 were identified, the FDA stated that there was a ‘lack of substantial evidence of effectiveness’ due to ‘a lack of adequate and well-controlled investigations’ in the literature-based NDA submission.”

On this news, Aldeyra’s stock price fell $2.92, or 27.4%, to close at $7.72 per share on June 21, 2023, thereby injuring investors.

The complaint filed in this class action alleges that throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material adverse facts about the Company’s business, operations, and prospects. Specifically, Defendants failed to disclose to investors that: (1) the ADX-2191 NDA did not include adequate and well-controlled investigations and thus failed to show substantial evidence of ADX-2191’s effectiveness; (2) as a result, the FDA was unlikely to approve the ADX-2191 NDA in its current form; (3) accordingly, the Company had overstated ADX-2191’s clinical and/or commercial prospects; and (4) as a result, Defendants’ positive statements about the Company’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis at all relevant times.
