Abstract/full free access: The distribution of the therapeutic monoclonal antibodies cetuximab and trastuzumab within solid tumors

Conclusions

Cetuximab (Erbitux) and trastuzumab (Herceptin) distribute slowly, but at higher doses achieve a relatively uniform distribution after about 24 hours, most likely due to their long half-lives in the circulation. There remains poor distribution within hypoxic (hypoxia - a deficiency of oxygen reaching the tissues of the body) regions of tumors.
