About ProKidney

ProKidney, a pioneer in the treatment of CKD through innovations in cellular therapy, was founded in 2015 after a decade of research. ProKidney's lead product candidate, REACT™ (Renal Autologous Cell Therapy), is a first-of-its-kind, patented, autologous cellular therapy with the potential to not only slow and stabilize the progression of CKD, but in some cases possibly drive meaningful improvement in kidney function. Late-stage CKD, Stage 3b - 4, is a key target for REACT™ therapy. REACT™ has received Regenerative Medicine Advanced Therapy (RMAT) designation, as well as FDA and EMA guidance, supporting its ongoing Phase 3 clinical program, which launched in January 2022.

About CKD

There are no therapies that effectively reverse late-stage CKD. CKD is a serious diagnosis with significant morbidity and mortality, notable for the 5-year mortality of a new diagnosis of CKD Stage 4 being higher than that of a new non-metastatic cancer diagnosis. CKD most often presents as a progressive decline in kidney function ultimately resulting in the failure of the kidneys and the need for renal replacement therapy, such as hemodialysis, or kidney transplant. One in three Americans is at risk for CKD, which currently affects approximately 75 million people in the United States and Europe and over 400 million across Asia. CKD is among the largest single expenses incurred by the US Health care system.
