A Phase 4 interventional study of Intervention Name in Chronic Kidney Disease, sponsored by Huashan Hospital. Recruiting at 1 site in China. Open to participants aged 61 Years and older. Per ClinicalTrials.gov, last updated 2026-08-03.
Sponsored by Huashan Hospital · Phase 4, Interventional, and Treatment
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.
3,090 studies on the registry are indexed under Renal Insufficiency, Chronic; 698 are open to participants now.
This study's planned enrollment of 300 is above the median of 73 across 2,157 interventional studies indexed under Renal Insufficiency, Chronic.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Participants will receive Niaoduqing Granules 5 g orally three times daily at 6:00, 12:00, and 18:00 after meals for 12 months. Usual treatments for chronic kidney disease, age-related comorbidities, and other chronic conditions will be continued or adjusted according to specialist recommendations.
Drug: Intervention Name
Niaoduqing 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.
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 60
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 60
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 60
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 60
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.
Time frame: From baseline through Month 60
All-Cause Mortality
The number and percentage of participants who die from any cause during the study follow-up period.
Time frame: From baseline through Month 60

Started Dec 2025 (actual). Primary completion is estimated for Nov 2030, 59 months after the start.
Of 100 non-industry phase 4 interventional studies under Renal Insufficiency, Chronic, half reached primary completion within 46 months of starting (the median), counting those still running; a quarter within 24 and three quarters within 67. This study's planned 59 months is above that.
Counting every sponsor, half of 116 studies reached it within 43 months; a quarter within 22 and three quarters within 67.
