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.
