Ardelyx Inc (NASDAQ: ARDX), a biopharmaceutical firm focused on discovering, commercializing, and developing first-in-class medicines to enhance kidney and cardio-renal diseases treatment. Yesterday they announced that it obtained a letter on July 13, 2021, from the US Food and Drug Administration noting that as a portion of its ongoing review of the firm’s New Drug Application for the supervision of serum phosphorus in the adult patients chronic kidney disease on dialysis. As a result, the FDA has specified deficiencies that preclude the discussion of labeling and post-marketing regulations at this time. Moreover, the message asserted that the notification does not indicate a final decision on the information under review. Immediately the firm requested a meeting about deficiencies and was notified by the FDA yesterday that it refused the request for a meeting. 

The FDA did not give specific details about the deficiencies, and the FDA noted that a critical issue is the size of the treatment effect and its clinical relevance.   

Mike Raab’s Statement

Ardelyx’s Chief Executive Officer and President Mike Rabb said that this is incredibly disheartening and disappointing communication from the FDA. Especially following the weeks of label discussions in early April, their NDA submission comprised their pivotal trials across 1,000 patients. They met their major and minor endpoints, and the additional information analyses they submitted in April responded to the FDA’s requests. Also, he adds that they plan to work with the FDA to learn more about the identified shortcomings and seek to settle them as soon as possible.
