NCT02741960

Brief Summary

This is a multicenter, randomised, double-blind placebo controlled trial on the efficacy and safety of add-on metformin to conventional immunosuppressants in systemic lupus erythematosus (SLE). The purpose of this study is to evaluate: 1) the effect of metformin on reducing disease flares; 2) the influence of metformin on corticosteroid sparing effect; 3) the influence of metformin on body mass index (BMI); 4) the safety of metformin.

Outcome Measures

Primary Outcomes (1)

  • numbers of participants who remained at risk of flares at each visit

    the effect of metformin on reducing disease flares

    one year

Secondary Outcomes (3)

  • changes in prednisone dose from baseline at each visit

    one year

  • changes in BMI from baseline at each visit

    one year

  • number of participants with treatment-related adverse events

    one year

Study Arms (2)

metformin

EXPERIMENTAL

Eligible patients for clinical trial were randomized in a 1:1 ratio to metformin/placebo add-on. Subjects randomized to metformin will receive a target dose of 500 mg three times daily. Investigators were allowed to adjust the dose according to the patients' tolerance.

Drug: metformin

placebo

PLACEBO COMPARATOR

Drug: placebo

Interventions

  • Patients who used cyclophosphamide 6-months before screening; used biological agents 12-months before screening;
  • Previous exposure of metformin within 30 days before screening; or previous history of intolerant to metformin;
  • Patients who diagnosed of diabetes mellitus;
  • Pregnancy or lactation.
