The patients received a total of 20 course of ch14.18 at dose levels from 10 mg/m2 to 200 mg/m2. The plasma clearance of ch14.18 was biphasic. Following the first course of treatment t1/2,α was 3.4±3.1 h and t1/2,β 66.6±27.4 h in 9/10 children. The t1/2,β values were significantly less than those of 181±73 h previously reported in adult melanoma patients ( P ≦ 0.001 ), and 147.5 h in the adult osteosarcoma patient in our trial. The latter suggests different pharmacokinetics of mAb ch14.18 in children and adults. After a second course of treatment, administered to 5/10 children, t1/2,β decreased significantly from 72.9±19 .8 h to 31.7±18.4 h( P = 0.015 ). We therefore conclude that the elimination kinetics of mAbs ch14.18 in children and adults are different, and furthermore that repeated administration of mAb ch14.18 to children with neuroblastoma leads to accelerated antibody clearance. |
