Ardelyx is a specialized biopharmaceutical company focused on developing medicine to improve treatment for people with cardiorenal disease, including patients with chronic kidney disease (“CKD”) on dialysis suffering from elevated serum phosphorus, or hyperphosphatemia.

In June 2020, Ardelyx submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (“FDA”) for its lead product candidate, tenapanor, a supposedly first-in-class medicine for the control of serum phosphorus in adult patients with CKD on dialysis. Ardelyx’s NDA was purportedly supported by successful Phase 3 studies, which, according to the complaint, showed “improvements” over current treatments and supported tenapanor’s “clinical safety and efficacy,” reinforcing its “potential” to be a “transformative” treatment.

After the market closed on July 19, 2021, however, Ardelyx revealed that it had received a letter from the FDA stating that it had detected issues with both the size and clinical relevance of the drug’s treatment effect.

On this news, the Company’s share price declined, falling $9.71 per share, or nearly 74%, to close at $2.01 per share on July 20, 2021.
