This is a prospective, cohort, multicenter study. Cohort 1 is treatment group. All eligible subjects will receive Vebreltinib (200 mg bid po) after signing the informed consent and meeting the inclusion/exclusion criteria, until disease progression, intolerable toxicity, or death. Subjects will undergo MET abnormality testing after enrollment, including MET amplification or MET protein overexpression.
Cohort 2 is external reference group. Subjects diagnosed with CCS and met the inclusion criteria but refused to enter Cohort1 will receive the standard treatment decided by investigators. These subjects will receive follow-up. The efficacy and safety data will be collected.
Imaging evaluation will be performed using RECIST v1.1, with CT or MR plain scans every two months (7 days) until disease recurrence or death.
During the study, subjects will receive safety follow-up, and survival follow-up will be conducted every two months after treatment, which can be done by telephone interview for approximately 3 years after treatment ends.
