Bevacizumab, as a humanized vascular endothelial growth factor (VEGF) antibody, is a highly effective monoclonal antibody. Bevacizumab can be used for the research of cancer^[1][2].

Bevacizumab-loaded hydrogel results in significant tumor reduction. Bevacizumab is taken up by other organs, including the heart, lung, and spleen. Bevacizumab accumulates higher within tumors via Bevacizumab-loaded hydrogel administration from 14 days onward as compared to the solution formulation. Bevacizumab (I.v.) solution, a typical drug clearance profile is observed where the antibody is cleared from the circulatory system with a half-life of ~4~5 days. The Bevacizumab-loaded hydrogel and the weekly administration of Bevacizumab solution inhibits tumor growth/metastasis in the peritoneal cavity, while one-time i.v. injection of Bevacizumab solution does not provide any therapeutic effect, leading to extensive tumor metastasis^[2].
