Tarlatamab is a cancer medicine used in adults with extensive-stage small cell lung cancer when the disease has progressed after platinum-based chemotherapy. It is a bispecific antibody that binds to DLL3 on tumour cells and to CD3 on T cells. By bringing these cells close together, it helps the immune system recognise and attack cancer cells.
Treatment is given as an intravenous infusion in a specialised oncology setting. The first doses require particularly close monitoring because important reactions are more likely early in treatment. Your healthcare team may give medicines before the infusion, provide fluids, perform blood tests and observe you in hospital or clinic after dosing. The exact schedule is decided by the oncology team.
The most important risks are cytokine release syndrome and neurologic reactions. Other possible side effects include tiredness, decreased appetite, altered taste, constipation, nausea, anaemia, low white blood cells, infections and changes in liver blood tests.
Patients and caregivers should know which symptoms require urgent medical help: fever, worsening shortness of breath, severe dizziness, confusion, sudden weakness, severe headache or signs of infection. Tarlatamab is not a routine medicine to take at home; it requires an experienced care team, structured monitoring and rapid reporting of any significant change in condition.
