Abstract

Mouse mAbs directed against the α/β-TCR were tested in clinical phase II and in triple-blind, randomized phase III studies. A clinical phase II trial administered 50 mg of murine anti-human α/β-TCR mAb (BMA 031) intravenously on the day of, as well as 2 and 4 days after, cadaveric donor renal transplantation in combination with a CsA/prednisone regimen. None of 12 patients showed even moderately adverse side effects. A phase III, triple- blind randomized trial enrolled 24 patients in the BMA 031 group and 22 patients in a placebo control group. BMA 031 treatment significantly reduced the incidence of rejection events within the first 10 posttransplant days to 1 patient versus 9 episodes in the placebo group (P<0.01). By the end of 30 days, 6 rejection episodes had occurred in the BMA 031 group and 11 in the control cohort (P=NS). After a minimum of 30 months follow-up, the actual allograft survival rate was 87% in the BMA-treated group compared with 68% in the control cohort.
