title: Multicenter, randomized study of the effectiveness of basiliximab in avoiding addition of steroids to cyclosporine a monotherapy in renal transplant recipients.
abstract: BACKGROUND
  Steroid therapy is associated with an increased risk of cardiovascular events and well-documented adverse effects, but two thirds of patients initiated on monotherapy with cyclosporine A (CsA) microemulsion require addition of steroids.
  
  
  METHODS
  In this 12-month randomized, double-blind, multicenter study, 108 renal transplant recipients were randomized and received basiliximab (n=52) or placebo (n=56) to assess whether basiliximab reduces the need for addition of steroids or other adjunctive immunosuppressive drugs to CsA monotherapy.
  
  
  RESULTS
  The primary endpoint of the study (requirement for additional immunosuppression at 12 months posttransplant) occurred significantly less frequently with basiliximab (54%) than placebo (73%) (P=0.046). By the end of the study, 25% of basiliximab-treated patients were receiving maintenance steroids versus 61% of placebo-treated patients (P=0.0006). During the trial, 33% of basiliximab-treated patients received oral steroids at some time compared with 61% of placebo-treated patients (P=0.004). The proportion of patients experiencing biopsy-proven rejection was not significantly different between the basiliximab (29%) and placebo (43%) groups (P=0.16). Median serum creatinine at 12 months was 141 mumol/L with basiliximab and 164 mumol/L with placebo (not significant). One-year graft and patient survivals were 88% and 98% for basiliximab and 88% and 96% for placebo (not significant), respectively. Adverse events were similar in the basiliximab and placebo treatment groups.
  
  
  CONCLUSIONS
  These findings demonstrate that the addition of basiliximab significantly reduces the need to modify the initial treatment regimen in patients scheduled to receive steroid-free CsA therapy, suggesting that basiliximab induction may be useful as a strategy in other steroid-avoidance regimens.
