Pharmacokinetic Disposition and Biodistribution of the Monoclonal Antibody ior EGF/r3 in rats, dogs and rabbits. MoAb ior EGF/r3 is well known by its antitumoral properties due to its anti-EGFr action. This survey was focused on the pharmacokinetic analysis of this drug in three different species, i.e., Wistar rats (at three dosage: 0.5, 1 and 2 mg), F1 rabbits and Beagle dogs, by bolus iv administration. The serum MoAb concentrations in rats were measured by radiobinding assay at several time points ranging from 30 min to 96 h, as 5 replication. At higher doses the pharmacokinetic biexponential decay profiles were fitted according to bicompartmental analysis, but at lower 0.5 mg dose the data points were better fitted using a monocompartmental modeling approach. It was reported the pharmacokinetic parameters with significant differences for t 1/2 ß (31,66-68,07 h, p<0,05) and CL (1,35-2,68 mL/h, p<0,05). showing a dose- dependence disposition pattern. There no exist significant uptake of the 99m Tc- ior EGF/r3 into the organs, but liver and kidney, which are both associated with its elimination clearance, although their values were not higher than 7.03 percentage of radioactivity/total organ weight. The pharmacokinetically characterized drug in rabbits and dogs was better fitted to biexponential elimination pofiles. The regularity of the drug disposition time course was provided in both species, without significantly differences between animals. Finally, the elimination half-lives of 35.3 h (rabbits) and 35 h (dogs), supported its potential for further clinical administration.
