Brief Summary

Prospective, multi-center, randomized, controlled, trial to compare tacrolimus with mycophenolate mofetil (MMF) for induces complete remission in lupus nephritis patients. The study duration is one year.

Research hypothesis

• The proportion of patients who have achieved complete remission between regimen of tacrolimus plus prednisolone is greater than MMF plus prednisolone as an induction therapy in lupus nephritis.

Detailed Description

The patients with a pathological diagnosis of active lupus nephritis whom are currently followed up or referred to outpatient department (OPD) of 7 participating medical centers in Thailand. Patients who come to attend will be selected according to the inclusion and exclusion criteria.

Outcome measurements

• The patients will be follow-up for 1 year and will be evaluated for clinical manifestations and laboratory investigations of lupus nephritis and any adverse effects of therapy on each visit.
• Blood pressure and laboratory assessments, including complete blood cell count, urinalysis, urine protein creatinine ratio (UPCR), and kidney and liver function, will be performed at each visit for 24 weeks and at the end of study (48 weeks).
• Serum anti-double-stranded DNA antibodies and serum C3 will be measured every 8 weeks after treatment until 24 weeks and at the end of study (48 weeks).
• A fasting lipid profile will be also measured every 8 weeks until 24 weeks and at the end of study (48 weeks).
• Renal and extrarenal disease activity of SLE was measured using the SLEDAI2K. The SLEDAI2K will be evaluated at the time of entry into the study and every 8 weeks after treatment until 24 weeks and at the end of study (48 weeks).
• SLICC damage index, SF-36, EQ5D, and SLEQOL will be evaluated at the time of entry, at 24 weeks, and at the end of the study.
• Patients' serum and urine (blood 3ml and urine 50 ml) will be collected at baseline, 2nd week, 4th week, 12th week, and 48th week for further analysis of biomarkers in the future.

Study Groups

Mycophenolate Mofetil (MMF)

MMF was initiated at a dose of 500 mg twice daily (for patients \> 50 Kg and Estimated Glomerular Filtration rate (eGFR) \> 60 ml/min) for 2 weeks, and advanced to 750 mg twice daily in LN patients weighing less than 50 kg or 1,000 mg twice daily in LN patients weighing 50 kg or more. .

Group Type: ACTIVE_COMPARATOR

Tacrolimus vs. Mycophenolate mofetil for Induction Therapy in Lupus Nephritis

Intervention Type: DRUG

Patients were randomly assigned to receive regimen I or II: TAC plus prednisolone (TAC group) or MMF plus prednisolone (MMF group). TAC was started at a dosage of 0.1 mg/kg/day divided into 2 daily doses at 12-hour intervals, and the dosage was titrated to achieve trough blood concentrations of 6-10 ng/mL in the first and second month and then 4-8 ng/mL., thereafter. MMF was initiated at a dose of 500 mg twice daily (for patients \> 50 Kg and Estimated Glomerular Filtration rate (eGFR) \> 60 ml/min) for 2 weeks, and advanced to 750 mg twice daily in LN patients weighing less than 50 kg or 1,000 mg twice daily in LN patients weighing 50 kg or more. Patients received concomitant prednisone at a dose of 0.5-0.7 mg/kg/d (maximum 60 mg/day), with tapering by 5-10 mg/day every 2 weeks until a dose of 5 mg/d has been achieved, and this dosage was maintained until the end of 24 weeks.

Tacrolimus (TAC)

TAC was started at a dosage of 0.1 mg/kg/day divided into 2 daily doses at 12-hour intervals, and the dosage was titrated to achieve trough blood concentrations of 6-10 ng/mL in the first and second month and then 4-8 ng/mL., thereafter
