- People who had brain or central nervous system tumours that have already been treated, as long as treatment (radiation or surgery) was completed more than 28 days before joining.
- People who are able to become pregnant must agree to use a highly effective form of contraception from the start of the study until 6 months after the last dose.
- People who are breastfeeding must be willing to stop breastfeeding from the start of treatment until 6 months after the last dose.

- People who previously had severe immune-related side effects (grade 3 or 4) from checkpoint inhibitor treatments.
- People who have previously been treated with a drug called Lenvatinib.
- People who have had a serious allergic reaction to drugs similar to those used in this trial.
- People who had surgery to the abdomen, pelvis, or chest within 3 months before joining.
- People who have been diagnosed with another cancer within the past 24 months (though some exceptions may apply for certain treated skin cancers or in-situ cancers — confirm with trial site).
- People who had a blood clot in an artery or vein within the 6 months before joining.
- People who had a stroke or mini-stroke (TIA) within the 6 months before joining.
- People with significant heart failure that affects daily functioning, based on a standard heart health scale (NYHA Class III or IV).
- People with a specific abnormal heart rhythm reading on an ECG, or evidence of a serious type of heart block.
- People whose heart pumping strength (ejection fraction) is below 50% on an echocardiogram (heart ultrasound).
- People who are currently taking blood-thinning medications such as warfarin, heparin, or similar drugs.
- People with a history of a serious abnormal connection (fistula) between body organs or tissues (grade 3 or higher).
- People whose scans show cancer growing into major blood vessels.
- People who have coughed up blood or had tumour-related bleeding within 1 month before joining.
- People with conditions affecting how the gut absorbs medication, including certain gut surgeries or disorders.
- People with a primary immune system deficiency condition.
- People with an active autoimmune disease, or a history of autoimmune disease that requires immune-suppressing medications (confirm with trial site for possible exceptions, such as vitiligo or hormone replacement conditions).
- People who have been taking corticosteroid medicines at doses higher than a low maintenance level within 14 days before joining (topical creams, eye drops, and ointments are generally allowed — confirm with trial site).
- People who have received an organ transplant or a stem cell transplant from a donor.
- People who are HIV-positive.
- People who are pregnant.
