About this trial
This prospective real-world study will evaluate the clinical benefits of Niaoduqing Granules in older adults with impaired kidney function. Approximately 300 participants aged over 60 years with stage 3 to 5 chronic kidney disease who are not receiving dialysis will be enrolled at Huashan Hospital, Fudan University. The study will examine whether treatment with Niaoduqing Granules is associated with slower kidney function decline and improvements in nutrition, frailty, and other health outcomes.
Participants will receive 5 g of Niaoduqing Granules three times daily after meals for 12 months, while continuing their usual treatment for chronic diseases as directed by their physicians. Kidney function, laboratory results, nutritional status, frailty, cardiovascular and cerebrovascular events, and survival will be assessed during follow-up. Blood, urine, and stool samples will also be collected to study changes in gut microorganisms and blood metabolites that may help explain how Niaoduqing Granules affect health. Participants will be followed for up to 60 months.

Intervention Name
DrugNiaoduqing Granules will be administered orally at a dose of 5 g three times daily at 6:00, 12:00, and 18:00 after meals with warm water for 12 months. Usual treatments for chronic kidney disease, age-related comorbidities, and other chronic conditions may be continued or adjusted according to specialist recommendations.

Trial outcomes
Primary outcomes
1
Occurrence of Rapid Kidney Function Decline
Rapid kidney function decline is defined as an annual decrease in estimated glomerular filtration rate (eGFR) of more than 5%. The occurrence of rapid kidney function decline will be determined using serial kidney function measurements obtained during follow-up.
Time frame
Every 12 months from baseline through Month 60Secondary outcomes
1
Incidence of Chronic Kidney Disease Complications
The number and percentage of participants who develop chronic kidney disease complications, including renal anemia and/or chronic kidney disease-mineral and bone disorder (CKD-MBD), during follow-up. Outcomes will be assessed using clinical evaluations and relevant laboratory test results collected according to the study protocol.
Time frame
Every 12 months from baseline through Month 602
Occurrence of Malnutrition
Malnutrition will be assessed using the Global Leadership Initiative on Malnutrition (GLIM) criteria. A participant will be classified as having malnutrition when at least one phenotypic criterion, including involuntary weight loss, low body mass index, or reduced muscle mass, and at least one etiologic criterion, including reduced food intake or absorption or disease burden/inflammation, are present.
Time frame
At baseline and every 12 months through Month 603
Occurrence of Frailty
Frailty status will be assessed using a rapid geriatric frailty screening scale. The number and percentage of participants identified as having frailty according to the screening assessment will be recorded.
Time frame
At baseline and every 12 months through Month 604
Occurrence of Cardiovascular and Cerebrovascular Events
The number and percentage of participants who experience one or more cardiovascular or cerebrovascular events during follow-up. Events include acute myocardial infarction, unstable angina, coronary heart disease, acute heart failure or worsening chronic heart failure, new-onset arrhythmia, acute cerebral infarction, transient ischemic attack, intracerebral hemorrhage, peripheral vascular disease, rheumatic heart disease, deep vein thrombosis, pulmonary embolism, valvular heart disease, or aortic disease.
