What is antibody-drug conjugates used for?

An antibody is designed to recognise a marker on or near a cancer cell. A linked drug travels with it and may be released after the conjugate enters or attaches to the target cell. This approach is intended to concentrate treatment where the target is present, although healthy cells can also be affected.

Whether an antibody-drug conjugate is suitable depends on the cancer type, test results for the target, previous treatment, and your general health. HER2-targeted treatment is one example of therapy that may use this targeted approach.

Before treatment, ask which target was found and how it was tested. Tell the team about medicines, allergies, lung or liver problems, and any previous reactions to infusions. Keep a record of new symptoms between appointments.

Contact the treatment team about fever, worsening breathlessness, a new cough, unusual bruising, severe tiredness, vision changes, or persistent vomiting. The team may check blood tests or adjust treatment when needed.

Seek urgent help for sudden breathing difficulty, facial or throat swelling, chest pain, fainting, or a severe infusion reaction. Call your oncology team promptly for fever, yellowing of the skin, dark urine, or rapidly worsening weakness.

Ask what target the medicine recognises, how it is given, which monitoring is needed, and which symptoms require an urgent call.
