Early trial tests arthritis drug against rare childhood brain tumor

This early-stage study is testing whether tocilizumab, a drug used for arthritis, can reach and potentially control a rare childhood brain tumor called craniopharyngioma. The trial has two parts: first checking if the drug gets into the tumor after one dose before surgery, then testing if regular doses for about a year can safely control tumor growth. It's for children and teens aged 2-21 with newly diagnosed or returning tumors, with follow-up for up to 5 years.
