8. Patients are not pregnant or lactating and required contraception;

9. Patients who are willing to provide written informed consent form (ICF) before the beginning of the study.

Exclusion Criteria:

1. Any antineoplastic therapy such as chemotherapy, biologic therapy, endocrine therapy, or immunotherapy within 4 weeks before the first dose of the study drug (or within 5 half-lives of other unmarketed study drugs, whichever is longer), except for the

following:

1. 6 weeks for Nitrosoureas or mitomycin C;

2. 2 weeks or five half-lives (whichever is longer) for oral fluorouracil and small molecule targeted drugs;

3. 2 weeks for Chinese herbal medicine with antineoplastic indications;

2. Patients with previous (within 2 years before screening) or concurrent other malignancies (only for phase Ib/Ic);

3. Patients had undergone major organ surgery (excluding needle biopsies) within 4 weeks before the first dose, with obvious trauma, or require elective surgery during the study;

4. Severe, non-healing fractures within 4 weeks before the first dose of the study drug;

5. The adverse reactions of previous antineoplastic therapy have not recovered to =grade 1 as determined by Common Terminology Criteria for Adverse Events (CTCAE) v5.0 criteria;

6. Patients who had received treatment with any drug that is a medium or strong inhibitor or inducer of cytochrome P450 (CYP) 3A4/5 enzyme activity within 2 weeks before screening or need to continue receiving such drugs;

7. Active brain metastases and/or carcinomatous meningitis;

8. Concurrent serious and/or uncontrolled medical conditions at screening (e.g., severe chronic obstructive pulmonary disease);

9. Patients with abnormal thyroid function were not allowed, except those with euthyroid function after drug control;

10. History of severe cardiovascular disease;

11. History of myopathy or raised creatine kinase (CK) >5 times the upper limit of normal (ULN);

12. Known hypersensitivity or intolerance to any component of the study drug or its excipients;

13. History of autoimmune disease, immunodeficiency disease, including HIV testing positive or other acquired, congenital immunodeficiency diseases, or organ transplantation;

14. Active hepatitis B virus, hepatitis C virus or active syphilis infection;

15. Active dysphagia, malabsorption or other chronic gastrointestinal diseases or conditions that may hamper compliance and/or absorption of the study drug;

16. Other ineligibilities according to the investigator.
