STAMP: Study of Tacrolimus vs Mycophenolate Mofetil in Pediatric Patients With Nephrotic Syndrome
Study Details
Study Description
Brief Summary
Primary nephrotic syndrome accounts for approximately 90% of the total number of nephrotic syndrome in childhood and it is the most common glomerular disease in children. Although treatment with steroids is uesful for primary nephrotic syndrome, proning to cause frequent relapse/steroid-dependent nephrotic syndrome after treatment, and the usage of immunosuppressive agents has become a new choice for the treatment of such patients. This study is a prospective, randomized, multicenter, open, parallel controlled trial, evaluating the efficacy and safety of steroid combined with the immunosuppressive agents which are tacrolimus and mycophenolate mofetil to children who with frequently relapsing or steroid-dependent nephrotic syndrome, all we wish to obtain the proper drug choice and individualized treatment options for children with nephrotic syndrome.

Detailed Description
Although steroids are recognized as first-line treatments for nephrotic syndrome, the vast majority of children relapse, and about half of them have frequent relapse or steroids dependence after treatment with steroids alone. Some children experienced steroids-resistance after multiple relapses, and eventually developed into chronic kidney dysfunction. Long-term or repeated application of large doses of steroids will lead to side effects such as obesity, growth retardation, and hypertension. Although the treatment of steroids with immunosuppressive agents is a new choice for the treatment of such patients, traditional immunosuppressive agents such as cyclophosphamide and cyclosporine A will bring some serious irreversible side effects, while immunosuppressive agents tacrolimus has the dual effects of immunosuppression and podocyte protection, and is more widely used in the department of nephrology, what's more, the other immunosuppressive agents mycophenolate mofetil has advantage of no kidney toxic, less adverse reactions and higher safety, which gradually being valued by nephrologists in recent years. This study mainly compares the efficacy and safety of tacrolimus and mycophenolate mofetil in the treatment of children with frequently relapsing or steroids-dependent nephrotic syndrome, in order to provide a more effective and safer treatment for children with nephrotic syndrome as well as the therapeutic medication options.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Tacrolimus(Group A) Tacrolimus: 0.5mg and 1mg; Capsule; 0.05-0.10mg/kg/day，BID; Steroid: 5mg; Oral tablets; 1.0-1.5 mg/kg, qod or 0.5-0.75 mg/kg/day, qd; |
Drug: Tacrolimus
The patients will be divided into two groups randomly. Tacrolimus dose: 0.05-0.10 mg/kg/day, BID. The concentration for tacrolimus is 5-10 ng/ml，then reduce the dosage of drugs to maintian the concentration for tacrolimus is < 5ng/ml. Total duration : 1 year.
Steroid dose: 1.0-1.5 mg/kg, qod or 0.5-0.75 mg/kg/day, qd， then gradually taper the steroid to 5mg/day.
Other Names:

| Experimental: Mycophenolate Mofetil(Group B) Mycophenolate Mofetil: 250mg; Dispersible tablets; 20~30mg/kg/day，BID; Steroid: 5mg; Oral tablets; 1.0-1.5 mg/kg, qod or 0.5-0.75 mg/kg/day, qd; |
Drug: Mycophenolate Mofetil
The patients will be divided into two groups randomly. Mycophenolate Mofetil dose: 20~30mg/kg/day，BID. The concentration for MPA-AUC is 30~50 μg.h/ml，then reduce the dosage of drugs to maintian the concentration for MPA-AUC is ≤40 μg.h/ml. Total duration : 1 year.
Steroid dose: 1.0-1.5 mg/kg, qod or 0.5-0.75 mg/kg/day, qd， then gradually taper the steroid to 5mg/day.
