Why: A recently filed securities fraud class action complaint alleges that Aldeyra Therapeutics, through certain of its officers and directors, made materially false and misleading statements regarding the Company's business, operations, and prospects. Specifically, it is alleged that the Company made false and misleading statements about or failed to disclose: (i) the ADX-2191 new drug application (“NDA”) did not include adequate and well-controlled investigations and thus failed to show substantial evidence of ADX-2191's effectiveness; (ii) as a result, the FDA was unlikely to approve the ADX-2191 NDA in its current form; (iii) accordingly, Aldeyra had overstated ADX-2191's clinical and/or commercial prospects; and (iv) as a result, Aldeyra’s public statements were materially false and misleading at all relevant times.
