About ProKidney

Biological Products, (No Diagnostic Substances), SIC 2836

ProKidney Corp. is a clinical-stage biotechnology company that develops autologous cell therapies to preserve kidney function in individuals suffering from chronic kidney disease and diabetes. Its lead product candidate, rilparencel, uses selected renal cells harvested from a patient's own kidney biopsy, which are processed and reinjected into the damaged organ through a minimally invasive procedure. Operating in a single segment, the company focuses on creating personalized regenerative treatments that eliminate the need for donor immunosuppression. Its end users are patients with advanced chronic kidney disease and diabetes.

The company maintains its principal executive offices in Winston-Salem, North Carolina, and is incorporated in Delaware following a corporate redomestication from the Cayman Islands. Its operational reach spans clinical research centers located across the United States, Mexico, and Taiwan. Additionally, it operates dedicated internal manufacturing facilities to process patient tissue and produce cell therapies.
