Summary

The TCM-WINE study is a single-center, prospective, double-blind randomized placebo-controlled trial. Based on optimal supportive care, the trial is aiming to assess superiority with regard to renal protection and reduction of severe treatment-related adverse events of Yi-Qi-Qing-Jie formula (YQF) combined therapy compared with immunosuppression monotherapy in high-risk IgAN.

Detailed description

The investigators plan to randomize 60 participants with biopsy-proven IgAN to a YQF combined group (YQF compound combined with prednisolone, and cyclophosphamide if necessary) or an immunosuppression group (placebo-YQF combined with prednisolone, and cyclophosphamide if necessary). The two groups will enter a 48-week in-trial treatment phase and receive post-trial follow-up until 50% (30/60) have a composite endpoint or have been followed for 3 years (study completion). All patients will receive optimal supportive care.

Conditions

• IgA Nephropathy at High Risk of Developing ESRD

Interventions

Type	Name	Description
DRUG	The Yi-Qi-Qing-Jie herbal compound	The compounds are blends of individual herbal extracts from YQF (consisting of Astragalus membranaceus, Saposhnikovia divaricata (turcz.) Schischk, Flos lonicerae, Angelica sinensis, Dioscorea nipponica, Hedyotis diffusa Willd, rhubarb, Spatholobus suberectus, with the effect of reinforcing Qi and activating blood, clearing away heat and poison, dissolving dampness and downbearing turbid) dissolved in 150 ml boiled water and taken orally twice a day for the duration of the treatment and follow-up phases.
DRUG	Immunosuppressants	Immunosuppression therapy comprises oral prednisolone (0.5-0.8 mg/kg/day; exact dose decided by the investigator, maximum dose not exceeding 60 mg/day) for 8 weeks, then tapered by 5-10 mg/day every 4 weeks, with a total treatment period of 24-32 weeks. Participants with persistent proteinuria ≥ 1 g/day after 8 weeks of corticosteroid monotherapy will receive 0.8-1.0 g of intravenous cyclophosphamide (CTX) every 4 weeks, total dose of not exceeding 8 g (exact dose decided by the site investigator). If severe CTX-related adverse events occur, such as alanine transaminase (ALT) exceeding the upper limit of two times, infections requiring hospitalization, granulocytes \< 3.0 × 109/L and platelets \< 50.0 × 109/L, CTX will stop being administered, symptoms will be treated, and adverse events recorded. Also, the frequency of detection will be increased to once every 2 weeks and the affected participant will be withdrawn if persistent infection or myelosuppression occurs.
OTHER	Optimized Supportive Care	The optimized supportive care included: 1. Lifestyle: low-salt, restricted protein dietary with sufficient calorie supply, smoking cessation, moderate alcohol consumption and keeping a healthy weight 2. The use of renin-angiotensin system blockade: lowering blood pressure to a target below 135/85 mmHg, during which treatment was adjusted to ensure that patients were receiving the maximum labelled or tolerated dose of RAS blockade 3. Patients with Diabetes Mellitus received insulin or oral hypoglycemic agents to achieve HbA1c≤ 7.0% 4. Received uricosuric agents or xanthine oxidase inhibitors as necessary to achieve serum uric acid \<6 mg/dL in female, \<7 mg/dL in male
OTHER	Yi-Qi-Qing-Jie herbal compound placebo	Patients will receive Yi-Qi-Qing-Jie herbal compound placebo instead for the duration of the treatment and follow-up phases. The major component of the placebo is malt dextrin which looks, smells and tastes like YQF compound, and it comes in packaging with a similar appearance to YQF compound; it is also dissolved in 150 ml boiled water and taken orally twice a day.
