1. What Vyloy is and what it is used for

Vyloy contains the active substance zolbetuximab, which is a monoclonal antibody that can recognise and attach to certain cancer cells. By attaching to these cancer cells, the medicine is intended to kill them.

Vyloy is used to treat adults with stomach (gastric) or gastro-oesophageal junction cancer. The gastro-oesophageal junction is the place where the oesophagus (gullet) joins the stomach.

This medicine is given to patients whose tumours are positive for the “Claudin18.2 (CLDN18.2)”, and negative for the “Human epidermal growth factor receptor 2 (HER2)” proteins. It is given to patients whose gastric or gastro-oesophageal junction cancer cannot be removed by surgery or has spread to other parts of the body.

This medicine is given in combination with other anti-cancer medicines. It is important that you also read the package leaflets for these other medicines. If you have any questions about these medicines, ask your doctor.
