Hypertensive Nephropathy

This study will evaluate the effect of intravenous injection of umbilical cord tissue derived mesenchymal stem cells (UMSCs) on the improvement of renal function in patients with chronic kidney disease (CKD) at stage 3 or 4, with the change of estimated glomerular filtration rate (eGFR) as the primary endpoint, and other changes in renal function laboratory indicators, changes in other organ system function laboratory indicators, and adverse reaction events as secondary endpoints. This trial aims to further evaluate the efficacy and safety of UMCSs in CKD patients, and provide new insights into expanding the clinical treatment strategies, delaying the progression and improving the prognosis of CKD patients.

This study investigates the safety and efficacy of ACE Reno, an oral transmucosal solution containing standardized bioactive peptides and amino acids, in patients with nephropathy of various etiologies and stages. The trial evaluates whether 12 weeks of ACE Reno (1 mL sublingually four times daily) reduces albuminuria/proteinuria and stabilizes kidney function in participants with nephropathy due to diabetes, hypertension, autoimmune disease, reflux/UTI, chronic glomerulonephritis, unknown etiology, pre-dialysis CKD, or post-transplant proteinuria. Nephropathy remains a global health burden, with \~9-10% of the population affected by chronic kidney disease (CKD), equating to \>750 million individuals worldwide. The socioeconomic costs are substantial: in England CKD costs \~£7 billion annually, projected to rise to \~£14 billion by 2033; in Malaysia, prevalence rose from 9% to 15.5% within 7 years; in Egypt, CKD imposes heavy familial and financial burdens, especially for pediatric patients; in Turkey, CKD is among the top causes of disability, linked to the rising tide of diabetes, obesity, and hypertension. ACE Reno is designed to address multiple drivers of CKD progression - glomerulosclerosis, fibrosis, endothelial dysfunction, and maladaptive RAAS/aldosterone signaling - through its peptide components that mimic antifibrotic (BMP-7, HGF, Klotho-like) and vasodilatory/cGMP-mediated (natriuretic peptide-like) pathways.
