At METUPUK, we campaign for new and better therapies for patients with secondary breast cancer. One of our recent campaigns, #TrodelvyNow helped to make a new type of drug, Trodelvy (sacituzumab govitecan) available for SBC patients in the UK. Scientist and METUPUK volunteer, Helen, explains how Trodelvy works and why it’s important that more drugs like this get to patients urgently.
