About Ardelyx

Ardelyx makes medicines for people with gut and kidney problems. These drugs help adults manage painful stomach issues and complex mineral levels. The company focuses on creating treatments that work locally in the intestines.

Treating the Gut and Kidneys

  • IBSRELA: Oral medicine for adults with irritable bowel syndrome with constipation; this condition involves stomach pain and difficulty passing stool.
  • XPHOZAH: Therapy used to lower high phosphorus levels in adults on kidney dialysis.
  • RDX10531: Next-generation inhibitor currently under development for multiple medical uses.
  • Discovery Assets: Early programs targeting potassium and electrolyte disorders in patients with heart or kidney disease.

Global Partners and New Trials

  • Partnered with Knight Therapeutics to bring tenapanor to the Canadian market in March 2021.
  • Formed a deal with Kyowa Kirin in Japan to launch PHOZEVEL for kidney patients in February 2024.
  • Announced approval for tenapanor in China through a license with Fosun Pharmaceutical in February 2025.
  • Started a Phase 3 clinical trial in January 2026 to test tenapanor for chronic idiopathic constipation.
  • Licensed a portfolio of TGR5 agonist compounds to METiS for therapeutic development.

Stopping Absorption at the Source

Ardelyx uses a specific mechanism that stops phosphate absorption at its primary entry point in the body. The company controls a patent portfolio with seven U.S. patents protecting its lead drug until at least 2029.

The 2025 Financial Story

  • Revenue reached $125.2 million in Q4 2025, up 7.8% from $116.1 million in Q4 2024.

  • Net income turned negative at a loss of $407,000 in Q4 2025, down 108.8% from a profit in Q4 2024.
  • Free cash flow hit $20.6 million in Q4 2025, up 123.4% from $9.2 million in Q4 2024.
  • Cash and short-term investments totaled $264.7 million at the end of 2025, up 5.8% from the previous year.

Bottom Line

Ardelyx has transitioned from a research firm to a commercial company selling treatments for chronic conditions. Its focus on specialized partnerships and expanding drug uses supports its position in the biotechnology sector.
