Biodistribution and pharmacokinetics of 125I-labeled monoclonal antibody M75 specific for carbonic anhydrase IX, an intrinsic marker of hypoxia, in nude mice xenografted with human colorectal carcinoma.
Original language description
Carbonic anhydrase IX (CA IX) is frequently expressed in human carcinomas and absent from the corresponding normal tissues. Strong induction by tumor hypoxia predisposes CA IX to serve as a target for cancer diagnostics and therapy. Here we evaluated targeting properties and pharmacokinetics of CA IX-specific monoclonal antibody (MAb) M75. Binding parameters of 125)I-labeled M75, including equilibrium dissociation constant, hypoxia-related binding to various cell lines and internalization, were analyzedin vitro. Biodistribution of (125)I-M75 in nude mice bearing HT-29 human colorectal carcinoma xenografts with hypoxic pattern of CA IX expression was studied by measurements of radioactivity in dissected tissues and macroautoradiography of tissue sections. Pharmacokinetics of intravenously administered (125)I-M75 was described using a 2-compartment model. Blood clearance showed a distribution phase t(1/2)(alpha) = 3.4 hr and an elimination phase t(1/2)(beta) = 55.3 hr postinjection. Des
