ARDX Investors Have Opportunity to Lead Ardelyx, Inc. Securities Fraud Lawsuit

$ARDXPress releaseSep 21, 2026, 11:12 AM ETRead the release

Rosen Law Firm announced a securities fraud class action against Ardelyx (NASDAQ: ARDX) on behalf of purchasers of common stock between January 13, 2026 and August 6, 2026, with a lead plaintiff deadline of November 16, 2026. The complaint alleges Ardelyx issued misleading statements about the commercial performance and growth prospects of XPHOZAH and IBSRELA, specifically citing payer access and reimbursement barriers, stricter prior authorization, and step edit requirements that slowed new-patient starts and delayed prescriptions. This is a plaintiff-firm solicitation rather than an issuer disclosure: no class has been certified and the release contains no new company information.
