Exclusion criteria
Exclusion criteria: 1. Patients will not be admitted to the study if they meet any of the following criteria: 1) The patient had previously used KRAS inhibitors or targeted EGFR therapy; 2. known allergy to the investigational drug or any of its components; 3. Systemic antitumor therapy, including chemotherapy, targeted therapy and immunotherapy, has been received within 28 days before the first dose (including no treatment) City of clinical investigational drugs or treatments), except for the following: oral fluorouracil and small molecule targeted drugs for first use The first 14 days of the study of the drug or the five half-lives of the drug (whichever is longer). Chinese medicines with anti-tumor indications are Within 14 days before the first use of the investigational drug; Surgical treatment (except diagnostic surgery) within 28 days prior to initial dosing; The first Patients who received local treatment such as radiotherapy, intervention or ablation within 14 days before secondary administration; 4.

Have a history of meningeal metastasis or current meninges 15 Transfer the subject. At least 2 weeks before the first dose, if the subject has received adequate local treatment for CNS metastasis Treatment (surgery or radiation) without the need for hormone therapy and neurological return to baseline (associated with CNS treatment) Except for remaining signs or symptoms), can be included in the group; 6.
