Radical radiotherapy within 4 weeks; 4. Have received local anti-tumor treatment within 4 weeks; 5. Major surgery requiring hospitalization or incomplete healing of the surgery incision within 4 weeks; 6. Current or prior history of retinal detachment; 7. Using a strong inducer or inhibitor of cytochrome P450 3A (CYP3A) within 2 weeks or 5 half-lives of the study treatment; 8.

Patients currently has central nervous system metastases, meningeal metastases or spinal cord compression, except in individual cases; 22. Any other medical condition or clinically significant laboratory abnormalities judged by the investigator would make the patients unsuitable to participate in this study.
