Item 8.01 Other Events
Ardelyx, Inc. (the “Company”) a biopharmaceutical company founded with a mission to discover, develop and commercialize innovative first-in-class medicines that meet significant unmet medical needs, today announced that the Office of New Drugs (OND), Center for Drug Evaluation and Research (CDER) of the U.S. Food and Drug Administration (FDA), has provided an interim response to the Company’s second level of appeal of the Complete Response Letter (CRL) received on July 28, 2021, for XPHOZAH. The OND noted that additional input from the Cardiovascular and Renal Drug Advisory Committee in general, and specifically, from experts, including expert clinicians, would be valuable in further considering the clinical meaningfulness of the phosphate lowering effect observed in the Company’s phase 3 clinical program for XPHOZAH. Accordingly, the OND intends to direct the Division of Cardiology and Nephrology to bring the XPHOZAH New Drug Application (NDA) to the Cardiovascular and Renal Drugs Advisory Committee, and to provide a response to the Company’s appeal within thirty (30) days after the conclusion of the Advisory Committee meeting. The Company is seeking approval for XPHOZAH for the control of serum phosphorus in adult patients with chronic kidney disease (CKD) on dialysis.
In addition, the Company is reporting that it has completed its data analyses of the Phase 2 dose ranging clinical trial for RDX013 evaluating the safety and efficacy of its potassium secretagogue for the treatment of hyperkalemia, or elevated potassium, in chronic kidney disease patients who are not on dialysis. While the results of the study demonstrated an acceptable safety and tolerability profile for RDX013 and supported proof of concept in its ability to lower serum potassium levels, with statistically significant reductions compared to placebo after eight days of treatment, the study did not meet its primary endpoint of significantly reducing serum potassium levels compared to placebo after four weeks of treatment. The Company currently expects that the next steps for the program will be to evaluate a new formulation that potentially enhances subject compliance and the efficacy of RDX013 in an additional Phase 2 clinical study at such time as the Company has determined its available resources support conducting such an additional clinical study after prioritization of the Company’s launch of IBSRELA® and preparations for the Advisory Committee for XPHOZAH.
