About this study
Official title: Effects of Chinese Herbal Medicine as an Adjunctive Therapy on Renal Function in Patients With Non-Diabetic Chronic Kidney Disease: A Pilot Randomized Controlled Trial
This study is a randomized controlled pilot trial designed to evaluate the effects and safety of a traditional Chinese medicine formula (CKD-1) as an add-on therapy to standard treatment in patients with stage 3-4 non-diabetic chronic kidney disease. Eligible participants will be randomly assigned to receive either standard care alone or standard care combined with CKD-1 for 12 weeks. Kidney function, urine protein levels, and quality of life will be assessed before and after the intervention. The study aims to provide preliminary evidence on whether CKD-1 can improve renal function and quality of life in this patient population.
Read the detailed description
This study is a prospective, single-blind (data analyst-blinded), randomized controlled pilot trial evaluating a traditional Chinese medicine formula (CKD-1) as adjunctive therapy in patients with stage 3-4 non-diabetic chronic kidney disease. Chronic kidney disease is a progressive condition with limited treatment options to slow renal deterioration. Traditional Chinese medicine is widely used as a complementary approach, but clinical evidence remains limited. This trial is designed to provide preliminary clinical evidence on the potential role of CKD-1 in improving renal outcomes and supporting future large-scale randomized controlled trials.

- Non-diabetic Chronic Kidney Disease

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Chinese herbal formula CKD-1Other
CKD-1 is a traditional Chinese herbal formula administered orally at a total daily dose of 13.5 g for 12 weeks. The formula consists of Astragalus membranaceus (3.0 g), Salvia miltiorrhiza (2.5 g), Poria cocos (2.0 g), Moutan cortex (1.5 g), Scutellaria baicalensis (1.5 g), Lonicera japonica (1.5 g), and Alisma orientale (1.5 g). It is used as an adjunct to standard care in patients with stage 3-4 non-diabetic chronic kidney disease.
| Study group | Role | What they receive |
|---|---|---|
| CKD-1 plus standard therapy | Experimental | Participants receive CKD-1 (13.5 g/day) orally in addition to standard care for 12 weeks. Standard care includes guideline-based management of blood pressure and kidney protection therapy, which remains stable during the study period. Receives: Other: Chinese herbal formula CKD-1 |
| Standard therapy alone | No intervention | Participants receive standard care alone for 12 weeks. Standard care includes guideline-based management of blood pressure and kidney protection therapy, maintained without addition of Chinese herbal medicine during the study period. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Estimated Glomerular Filtration Rate (eGFR)
Change in estimated glomerular filtration rate (eGFR) from baseline to week 12. eGFR is calculated using standard clinical laboratory methods. The primary endpoint is defined as the difference between eGFR at week 12 and baseline (ΔeGFR = eGFR_week12 - eGFR_baseline).
Measured: From baseline to 12 weeks of treatment
