ABSTRACT
Objective To evaluate the ocular pharmacokinetics of a novel antibody, MIL60, tar-geting vascular endothelial growth factor ( VEGF) after subconjunctival injection. Methods After subcon-junctival injection of MIL60 in rabbits, aqueous humour, vitreous from both eyes and peripheral blood were collected of each rabbit to analyze the concentration of MIL60 with ELISA. Results After subconjunctival administration, MIL60 could penetrate into the injected eye′s anterior chamber and vitreous, and maintained at an effective concentration in the aqueous or vitreous for about 10. 7 or 6. 8 days. Moreover, MIL60 could be found in the uninjected eye. Conclusion After subconjunctival injection, MIL60 could maintain at a therapeutic concentration in injected eyes. The pharmacokinetics analysis of MIL60 might provide some basis and guidance for its application in humans in the near future.
