During the screening phase, subjects must be diagnosed with non-small cell lung cancer (NSCLC) and test positive for EGFR-sensitive mutations (L858R and\u002For Exon 19Del).\n\n  4\\. Subjects who developed leptomeningeal progression after treatment with third-generation EGFR-TKIs and have no extracranial progression. The original third-generation EGFR-TKIs may be continued at the original dose or reduced dose.\n\n  5\\. Subjects diagnosed with leptomeningeal metastasis must have positive cerebrospinal fluid (CSF) cytology results. Subjects with negative CSF cytology but clinically diagnosed leptomeningeal metastasis based on symptoms, brain or spinal MRI imaging are also eligible for enrollment.\n\n  6\\. Subjects with both leptomeningeal progression and brain parenchymal progression are allowed to enroll.\n\n  7\\. Have undergone Ommaya reservoir implantation, with confirmation of no surgery-related complications and normal function of the Ommaya reservoir.\n\n  8\\. If accompanied by neurological symptoms, the following conditions must be met: able to take oral medication and swallow drugs; no need to increase hormone dosage to control central nervous system symptoms for at least 1 week prior to study treatment (i.e., symptom stability).\n\n  9\\. All anti-tumor therapy-related toxicities must have recovered to ≤ Grade 1 per CTCAE 5.0 criteria prior to starting study treatment (neurotoxicity related to platinum-based therapy may recover to ≤ Grade 2 per CTCAE 5.0 criteria); alopecia of any grade is allowed for enrollment.\n\n  10\\.

Subjects with a history of cranial or spinal radiotherapy within 6 months prior to study drug administration are ineligible for enrollment. Radiotherapy for bone metastases within 3 months prior to study drug administration is also not permitted.\n\n  2\\. Subjects who have undergone major surgical procedures (e.g., intrathoracic, intra-abdominal, or pelvic surgery) within 4 weeks prior to the first dose of study treatment, or who have not yet recovered from side effects related to such surgeries, are ineligible for enrollment.\n\n  3\\.

Subjects unable to discontinue the following medications within 1 week prior to study drug administration and during the study period:\n  1. Strong inducers or strong inhibitors of CYP3A4;\n  2. Drugs that may prolong the QT interval or induce torsades de pointes. 7. Subjects with prior or current HIV infection are excluded. HCV antibody-positive subjects may be enrolled if HCV RNA is undetectable (with the lower limit of detection defined per each center's standards) and there is no concurrent hepatitis B virus (HBV) infection. HBV-infected subjects may be enrolled if they meet the following conditions:\n\n  \u003C!-- -->\n\n  1. For active hepatitis B patients: at least 6 weeks of antiviral therapy prior to starting study treatment, with HBV DNA \\\u003C100 IU\u002FmL and ALT\u002FAST levels \\\u003CULN;\n  2.
