Exclusion criteria
Exclusion criteria: 1. With meningeal metastasis, brain stem metastasis, spinal cord metastasis and/or compression, or active CNS metastasis; 2.

Currently has a skin condition that requires oral or intravenous administration. 11. History of the following ophthalmic conditions: severe dry eye syndrome, severe keratitis, severe conjunctivitis, and other conditions judged by the investigator which may lead to an increased risk of corneal epithelial injury. 12.
