Safety and efficacy of an alternative basiliximab (Simulect) regimen after renal transplantation: administration of a single 40-mg dose on the first postoperative day in patients receiving triple therapy with azathioprine.
This was a multi-center, open-label, randomized, dose-comparative study on 202 renal transplantation patients. We evaluated for the first time an alternative dosing regimen for basiliximab, consisting of a single 40-mg intravenous dose on day 1 post-transplantation plus triple therapy, in comparison with the conventional two-dose regimen (2 h before transplantation and on day 4) plus triple therapy. At 6 months, the incidence of acute rejection was low: 22.5% of patients in the basiliximab 2 x 20-mg group and 20.0% of patients in the basiliximab 1 x 40-mg group experienced an acute rejection episode ( P = 0.628) (biopsy-proven rejection: 19.6% and 17.0%, P = 0.585). There was no statistically significant difference in any of the secondary efficacy parameters. The incidence of graft loss by 12 months was 4.9% and 6.0% in the 2 x 20-mg and 1 x 40-mg group, respectively ( P = 0.73). No differences were observed between the dosage groups with regards to safety assessments (adverse events (AEs), infections, vital signs, laboratory safety evaluations, and physical examinations). The data reveal that basiliximab can be safely and effectively administered as a single 40-mg dose on day 1 after renal transplantation as a therapeutic option to the established 2 x 20-mg dosing regimen. This alternative dosing regimen may be of significant convenience under circumstances when a first dose of basiliximab was not given prior to transplantation. Both regimens can conveniently be used during the initial hospitalization of the patient.
