Background Tacrolimus (FK 506), a macrolide compound isolatedfrom a bacterium, is a potent immunosuppressant with activityin solid-organ transplants. Most immunosuppressive regimensfor liver transplantation are based on cyclosporine.
Methods We conducted an open-label, randomized, multicentertrial to compare the efficacy and safety of tacrolimus-basedand cyclosporine-based immunosuppressive regimens for patientsreceiving a first liver transplant. A total of 478 adults and51 children ( 12 years of age) were randomly assigned at thetime of transplantation to receive tacrolimus (n = 263) or cyclosporine(n = 266) and were followed for one year. The primary end pointswere patient and graft survival at one year. The secondary endpoints were the incidence of acute rejection, corticosteroid-resistantrejection, and refractory rejection (continued rejection aftertwo courses of corticosteroids and an intervening course ofmuromonab-CD3).
Results According to Kaplan-Meier analysis, actuarial patient-survivalrates at day 360 were 88 percent for both the tacrolimus andcyclosporine groups (P = 0.85; 95 percent confidence intervalfor the difference, -5.4 to 6.6 percent), and graft-survivalrates were 82 percent and 79 percent, respectively (P = 0.55;95 percent confidence interval for the difference, -4.8 to 9.7percent). Acute rejection occurred in 154 patients in the tacrolimusgroup and 173 patients in the cyclosporine group (P<0.002),corticosteroid-resistant rejection occurred in 43 and 82 patients,respectively (P<0.001), and refractory rejection occurredin 6 and 32 patients, respectively (P<0.001). Tacrolimuswas associated with a higher incidence of adverse events requiringwithdrawal from the study, primarily nephrotoxicity and neurotoxicity;37 patients in the tacrolimus group and 13 in the cyclosporinegroup discontinued the study because of adverse events (P<0.001).
Conclusions After one year, immunosuppressive regimens basedon tacrolimus and cyclosporine were comparable in terms of patientand graft survival. Tacrolimus was associated with significantlyfewer episodes of acute, corticosteroid-resistant, or refractoryrejection, but substantially more adverse events requiring discontinuationof the drug.
