Eastern Cooperative Oncology Group (ECOG) performance status ≤ 1
Subjects are able to swallow and retain oral medication without any clinically significant gastrointestinal abnormalities that alter absorption
Subjects (including women and men) agree to use effective contraception for contraception from the time of signing the informed consent form to 180 days after the last use of the study drug. Female subjects of childbearing age cannot be pregnant or breastfeeding

Active bacterial, fungal, or viral infection requiring systemic therapy within 1 week prior to the first dose
Subjects with symptomatic central nervous system (CNS) metastases and/or cancerous meningitis
Cardiovascular and cerebrovascular diseases with clinical significance
Clinically uncontrollable serous effusion (eg, pleural effusion that cannot be controlled by drainage or other methods)

Hepatitis B virus surface antigen (HBsAg) positive and viral deoxyribonucleic acid (HBV DNA) > 2000 IU/ml or 104 copies/ml (only the centers that can perform qualitative examination, the HBV DNA test result is positive or high detection limit); hepatitis C virus antibody positive and viral ribonucleic acid (HCV RNA) positive
Other malignant tumors occurred within 2 years before study enrollment. (Except: Bowen's disease; cured basal cell or squamous cell skin cancer; prostate cancer with a Gleason score of 6; treated cervical carcinoma in situ.)
