- People who have a confirmed diagnosis of advanced stomach or gastroesophageal junction (stomach-oesophagus junction) cancer that cannot be surgically removed, or that has spread to other parts of the body, and who have not yet received treatment for this stage of the disease. People who previously had chemotherapy before or after surgery may also be considered, as long as their cancer came back more than 6 months after that treatment ended.
- People whose cancer has at least one measurable area of disease, as assessed by standard imaging guidelines.
- People whose cancer tests positive for a protein called CLDN 18.2.
- People whose cancer tests negative for a protein called HER2, and whose PD-L1 score (a measure of immune activity in the tumour) is below 5.
- People who are in relatively good general health, able to carry out everyday activities with minimal limitation (as rated on a standard medical scale called ECOG 0–1).
- People who are expected to live for more than 3 months.
- People aged 18 to 75 years.
- People whose blood tests show that their bone marrow, blood clotting, liver, and kidneys are functioning adequately.
- People of childbearing potential who agree to use effective contraception from the time of signing consent until 3 months after the last dose. Women of childbearing potential must have a negative pregnancy blood test within 72 hours before the first dose.

- People who have had major surgery within 4 weeks before starting the study treatment.
