Clinical Study of ICP-192 in Solid Tumors Patients

1. An unresectable or metastatic advanced malignant solid tumor confirmed by histopathology that has failed to respond to known treatment or has recurred;Subjects who progress under standard treatment, are intolerant to standard treatment, or do not have standard treatment (dose escalation phase)
2. Tissue or cell pathology confirmed unresectable, recurrent or metastatic (AJCC version 8 TNM staging IV (2017), biliary tract malignant tumor, or intolerance to first-line chemotherapy failure (twice (defined as reduction still cannot tolerate) first-line chemotherapy, neoadjuvant/progress/adjuvant chemotherapy after 6 months recurrence can be selected (dose extension stage); - At least one evaluable disease according to RECIST1.1
3. FGFR2 translocation/fusion has been reported or FGFR2 translocation/fusion has been detected in central laboratory (dose extension phase);
4. Age ≥18 and ≤75
5. There is at least one evaluable lesion according to RECIST1.1 criteria
6. ECOG strength score is 0-1 (dose escalation stage), and ECOG strength score is 0-2 (dose expansion stage).
7. The expected survival time is more than 3 months

8. The organ function level must meet the following requirements (subject to the upper limit of normal value in the clinical trial center):

   A) bone marrow: absolute count of neutrophils (ANC)≥1.5*109/L (1500/mm3), platelet ≥75*109/L, hemoglobin ≥9g/dL; B) coagulation function: international standardized ratio of prothrombin time and partial thrombin time \<1.5 times the upper limit of normal value; C) liver: serum bilirubin ≤1.5 times the upper limit of normal value (tumor involvement in the liver ≤2.5 times the upper limit of normal value), aspartic aminotransferase (AST) and alanine aminotransferase (ALT)≤3 times the upper limit of normal value (AST and ALT≤5 times the upper limit of normal value in the case of liver metastasis); D) serum creatinine ≤1.5 times the upper limit of normal value, or creatinine clearance ≥70mL/min (calculated according to the Cockroft-gult formula).

9. Volunteer to enroll and sign informed consent to follow the treatment protocol and visit plan.
