Inclusion Criteria 1. aged between ≥ 18 years and ≤75 years; regardless of male or female. 2. Histologically and/or cytologically confirmed diagnosis of non-small cell lung caner,and the clinical stage is IV(AJCC 4th）; Received at least one line of systemic treatment(including platinum-based chemotherapy ± PD-(L)1) during the stage IV, and disease progression occured during or after the treatment. 3. KRAS mutation positive. 4. ECOG score 0-1. 5. Expected survival time ≥ 3 months. 6．At least one intracranial measurable lesion according to RECIST v1.1 criteria. 7．Adequate organ function within 7 days before enrollment. 8. Recovery to ≤grade 1 or return to baseline from previous treatment-related adverse events (according to CTCAE 5.0), except for adverse events such as hair loss that are judged by the investigators to be safe and do not violate other inclusion criteria. 9\. Avoid excessive exposure to sunlight, and be willing to use sufficient sunscreen when there is expected to be sunlight exposure. 10\. Take contraceptive measures as required. Exclusion Criteria 1．Patients who have previously received any of the following treatments: 1. Prior treatment with MEK inhibitors、anlotinib or other VEGFR-TKI(such as cabozantinib, sorafenib, apatinib,etc); 2.

Radical radiotherapy within 28 days prior to the first dose; palliative radiotherapy allowed if ≥14 days before first dose; 6. Live or live-attenuated vaccine within 28 days prior to the first dose; other vaccines (e.g., inactivated COVID-19 vaccine) within 14 days prior to the first dose; 7.
