Adequate organ function as defined in the below: Hepatic function Aspartate transaminase (AST) and alanine transaminase (ALT) = 3 times upper limit of normal (ULN), or = 5 times ULN in the presence of liver metastases. Total serum bilirubin (TBIL) = 1.5 times ULN; TBIL=3×ULN and direct bilirubin(DBIL)=1.5×ULN in the presence of liver metastases or with Gilbert's syndrome. Bone marrow function No blood transfusion or hematopoietic stimulator treatment within 7 days; absolute neutrophil count (ANC) =1.5×10^9/L; platelets (PLT) count =75×10^9/L; hemoglobin (Hb) = 90 g/L. Renal function Creatinine clearance = 50 mL/min. Coagulation function International normalized ratio (INR) or prothrombin time (PT) = 1.5 times ULN. 7. Female patients with reproductive potential must have a negative serum pregnancy test within 7 days prior to the first dose. Both male and female patients of reproductive potential must be willing to abstain completely or agree to use an appropriate method of contraception during the entire study duration and for at least 3 months after the last dose of study medication. 8. Willingness and ability to give informed consent and follow protocol procedures, and comply with follow-up visit requirements. Exclusion Criteria: 1. Dose-escalation phase: patients with known driver alterations other than KRAS p.G12C, e.g., EGFR, ALK, ROS1, RET, TRK, etc. (Enrollment of patients with co-mutations may be discussed with the investigator). 2. Dose-expansion phase: prior use of selective KRAS inhibitors. 3. Patients who received chemotherapy, radiotherapy, biological therapy, endocrine therapy, immunotherapy, and other anti-tumor treatment within 3 weeks before the first administration, except for the following: Nitrosourea or mitomycin C was received within 6 weeks before the first administration; Oral fluoropyrimidines and small molecule targeted drugs within 2 weeks or 5 half-lives of the drug (whichever is longer) prior to the first administration; Chinese proprietary medicines with anti-tumor indications were received within 2 weeks before the first administration. 4. Received other unapproved investigational drugs or treatments within 4 weeks prior to the first administration. 5. Have undergone major organ surgery (excluding needle biopsy) or had significant trauma within 4 weeks prior to the first administration. 6. Unresolved toxicities from prior anti-tumor therapy, defined as not having resolved to Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 grade = 1(exceptions for toxicities judged by the investigator to be of no safety concern, e.g. alopecia, grade 2 peripheral neurotoxicity, etc.). 7. Presence of spinal cord compression, meningeal metastases, clinically symptomatic brain metastases, or need for increased steroid doses to control central nervous system (CNS) disease; patients with symptomatic CNS metastases that are already under control may be eligible for this study. 8. Patients with active infection who need systematic anti-infective therapy within 2 weeks prior to the first administration. 9. Active hepatitis (Hepatitis B: Hepatitis B virus surface antigen [HBsAg] positive with HBV DNA =2000 IU/mL; Hepatitis C: Hepatitis C virus antibody positive with HCV RNA =1000 IU/mL), HIV antibody positive, active syphilis (double positive for syphilis non-specific and syphilis specific antibodies) that is uncontrolled by treatment and inappropriate for enrollment as determined by the investigator. 10. Presence of other lung diseases requiring systemic treatment or severe lung diseases such as active tuberculosis, interstitial lung disease, etc., which in the opinion of the investigator may affect the interpretation of the study results or place the patient at high risk; 11. A history of serious cardiovascular and cerebrovascular disease, including but not limited to severe cardiac rhythm and conduction abnormalities, such as ventricular arrhythmias and degree II-III atrioventricular block requiring clinical intervention; Longer QT interval at rest (QTc > 470 msec for women or > 450 msec for men); Acute coronary syndrome, congestive heart failure, aortic dissection, stroke, or other grade 3 or higher cardiovascular and cerebrovascular events occurred within 6 months prior to first administration; Heart failure with the New York Heart Association (NYHA) Heart function rating = II or left ventricular ejection fraction (LVEF) < 50%; Clinically uncontrolled hypertension. 12. Strong inhibitor or inducer of CYP3A, P-glycoprotein inducer or inhibitor used within 1 week or 5 half-lives (whichever is longer) prior to the first administration or expected to be used during the study period. 13. Patients with malignancies other than tumors treated in this study (except malignancies that are cured and have not recurred within 2 years prior to study enrollment; completely resected basal cell and squamous cell skin cancer; completely resected carcinoma in situ of any type). 14. Severe gastrointestinal disease of clinical significance as determined by the investigator, including active ulcerative colitis, Crohn's disease, peptic ulcer disease, or previous surgical procedures that may have significantly affected drug absorption. 15. History of allergy to study drug components or adjuvants. 16. Pleural, abdominal, or pericardial effusions that are poorly controlled despite intervention (defined as effusion that has grown significantly within 2 weeks of removal and is symptomatic requiring re-puncture or other intervention). 17. Uncontrolled diabetes mellitus [fasting blood glucose =10 mmol/L and/or glycated hemoglobin (HbA1c) =8%], uncontrolled symptomatic hyperthyroidism or hypothyroidism, uncontrolled symptomatic hypercalcemia or hypocalcemia. 18. Have a coagulation disorder or bleeding tendency, including an arterial or venous thromboembolic event or any life-threatening bleeding event within 6 months prior to first administration, or have a lesion involving a major blood vessel, or have a bleeding tendency as determined by the investigator. 19. Pregnant or lactating women. 20. Presence of any condition that may increase the risks associated with the administration of the study drug or that may affect the interpretation of the study results, or poor patient compliance, or any other condition that, in the opinion of the investigator, makes the enrollment inappropriate. |
