What was measured

Blood samples were collected before and 30 minutes after the start of infusion and immediately (0 minutes), 30, 60, 90, and 120 minutes after the end of infusion of denileukin diftitox. The samples were analyzed for the amount of denileukin diftitox in the serum using a validated ligand-binding assay with a LLOQ of 30 ng/mL. Serum PK data were analyzed using a non-compartmental analysis approach to obtain individual participant estimates of t1/2, which was then summarized as the median and full range for all participants and expressed in minutes.
