NCT02488252

Brief Summary

This study aims to explore the effect of an adjuvant semi-individualized Chinese medicine treatment plan on type 2 diabetic patients with stages 2 to 3 chronic kidney disease and macroalbuminuria. This study will collect preliminary data on treatment effect, variance, recruitment rate and attrition rate for the planning of a subsequent clinical trial.

Study Arms (2)

Standard medical care

ACTIVE COMPARATOR

Angiotensin converting enzyme inhibitor or angiotensin receptor blocker and oral hypoglycemic agents or insulin at stable dose

Drug: Routine medical care (active comparator)

Chinese Medicine on top of standard medical care

EXPERIMENTAL

Semi-individualised Chinese Medicine treatment on top of standard medical care The treatment plan consists of 5 different formulas and will be prescribed to patients categorised to 5 subgroups according to clinical manifestation. Patients having multiple manifestations that fit more than 1 subgroup will not be included. Minor adjustment of the medication will be allowed and determined by the Chinese Medicine practitioner to reflect actual clinical practice. Dosage will follow strictly the China Pharmacopeia.
