Atrasentan

For the dual renal and cardiac risk control in patients with chronic kidney disease complicated with type 2 diabetes mellitus, the clinical value of highly selective endothelin A receptor antagonist drugs has continued to be highlighted in recent years, and atrasentan is a representative variety of this class of drugs. It competitively blocks the binding of endothelin to A receptors, inhibits vasoconstriction, inflammatory response and glomerulosclerosis progression. It can not only effectively reduce the urinary protein level of patients with chronic kidney disease complicated with type 2 diabetes mellitus, delay the progression of end-stage renal disease, but also reduce the risk of related cardiovascular adverse events, providing a new medication option for such patients whose treatment needs have not been fully met for a long time.

At present, the global atrasentan market is in a stage of rapid expansion. In 2023, the market size was approximately USD 170 million, with a compound annual growth rate of 26% in the recent 3 years. The original research product has only been approved for marketing in a small number of countries, and there are few enterprises developing generic drugs around the world, so the competitive landscape is relatively relaxed. No generic drug has been approved in China yet, and more than 5 enterprises have submitted marketing applications for generic drugs. As related indications are included in the clinical pathway recommendations, the domestic market is expected to enter a volume expansion period in the next 3 years. If there is no verifiable data, relevant market dimensions shall be subject to actual research results.
