Ardelyx is a specialized biopharmaceutical company that focuses on developing first-in-class medicine to improve treatment for people with cardiorenal disease. This includes patients with chronic kidney disease ("CKD") on dialysis suffering from elevated serum phosphorus, or hyperphosphatemia; and CKD patients and/or heart failure patients with elevated serum potassium, or hyperkalemia.

In June 2020, the defendants submitted a New Drug Application ("NDA") to the U.S. Food and Drug Administration ("FDA") for Ardelyx's lead product candidate, tenapanor, a supposedly first-in-class medicine for the control of serum phosphorus in adult patients with CKD on dialysis. If approved, tenapanor "would be the first therapy for phosphate management that blocks phosphorus absorption at the primary pathway of uptake[,]" and "could greatly improve patient adherence and compliance with one single pill dosed twice daily in contrast to current therapies where typically multiple pills are taken before every meal." Thus, tenapanor was widely touted by the defendants.

However, the truth was revealed after the markets closed on July 19, 2021, when the defendants announced that Ardelyx received a letter from the FDA on July 13, 2021, stating that "the FDA has identified deficiencies that preclude discussion of labeling and post-marketing requirements/commitments." In particular, the FDA noted that "a key issue is the size of the treatment effect and its clinical relevance."

The complaint alleges that throughout the Class Period, the defendants made materially false and misleading statements regarding tenapanor and the likelihood that it would be approved by the FDA. The complaint further alleges that the defendants possessed, were in control over, and, as a result, knew, or had reason to know, that the data submitted to support the NDA was insufficient in that it showed a lack of clinical relevance of the drug's treatment effect, making it foreseeably likely, if not certain, that the FDA would not approve the drug.

Ardelyx investors may, no later than September 28, 2021, seek to be appointed as a lead plaintiff representative of the class through Kessler Topaz Meltzer & Check, LLP or other counsel, or may choose to do nothing and remain an absent class member.  A lead plaintiff is a representative party who acts on behalf of all class members in directing the litigation.  In order to be appointed as a lead plaintiff, the Court must determine that the class member's claim is typical of the claims of other class members, and that the class member will adequately represent the class. Communicating with any counsel is not necessary to participate or share in any recovery achieved in this case. Your ability to share in any recovery is not affected by the decision of whether or not to serve as a lead plaintiff.
