Korábbi kezelés

• Prior treatment with drugs similar to the investigational product.
• Gastrointestinal obstruction, or signs/symptoms of gastrointestinal obstruction; however, patients who have undergone surgical intervention with complete resolution of the obstruction may be considered for screening.
• Concurrent biliary obstruction with risk of biliary tract infection (patients with treatable biliary obstruction may be enrolled if adequate biliary drainage is achieved and the risk of biliary infection is resolved after treatment).
• Third-space fluid collections (e.g., massive pleural effusion, ascites) that cannot be stabilised (i.e., no intervention required after drainage removal) within 2 weeks prior to enrolment; patients with only a small amount of fluid detected by imaging and without clinical symptoms may be enrolled.
• Severe infection within 4 weeks prior to enrolment, such as severe pneumonia, bacteraemia, or infectious complications requiring hospitalisation; unexplained fever >38.5°C within 2 weeks prior to enrolment ; signs/symptoms of infection requiring intravenous antibiotic therapy within 2 weeks prior to enrolment.
• Adverse events from prior therapy not recovered to NCI-CTCAE Grade ≤1 at enrolment .

• Severe cardiovascular or cerebrovascular diseases.
• Known or suspected interstitial lung disease (isolated imaging findings of interstitial changes are not excluded).
• History of definite neurological or psychiatric disorders, including epilepsy and dementia.
• History of malignancies other than the primary tumour within 5 years prior to enrolment, with the exception of malignancies with low risk of metastasis and death, such as adequately treated carcinoma in situ of the cervix, basal cell carcinoma, or squamous cell carcinoma of the skin.
