Within a primate species, group means in the same column with different numerical superscripts are significantly different (analysis of variance; α = 0.05).

  • 3-a  AUC is the calculated area under the Apo2L/TRAIL serum concentration vs. time curve; Cmax is the model-predicted maximum serum concentration of Apo2L/TRAIL; Vss is the estimated volume of distribution of Apo2L/TRAIL at steady-state.

  • 3-b  Reported half-life was calculated from the elimination rate constant (K10).
