The imaging evaluation should be completed within 28 days before enrollment, and the patient's hormone dosage should be stable for at least 5 days or more. 9. A fertile woman must have a negative serum pregnancy test within 28 days of the first study drug administration and agree to contraception between 28 days before the first study drug administration and 90 days after the last study drug administration; Male patients are required to undergo ligation or agree to contraception and refuse sperm donation from 7 days before the first dose to 30 days after the last dose; The failure rate of contraceptive methods<1% per year, such as double screen contraceptive methods, condoms, oral or injectable contraceptives. Exclusion Criteria: 1. Patients who received targeted therapy or tyrosine kinase inhibitor therapy within 2 weeks or within 5 half-lives (whichever is shorter) before starting administration, and who received chemotherapy, major surgery, radiotherapy, Anti-tumor biopharmaceutical treatment, immunotherapy or clinical trials within 4 weeks or within 5 half-lives (which is shorter); 2. Uncontrolled or symptomatic brain metastases (asymptomatic or stably controlled CNS metastases and no hormone therapy within 2 weeks are allowed to be enrolled);Patients with spinal cord metastasis with symptoms of spinal cord compression;Primary CNS tumors were allowed to be enrolled. 3. The toxicity of previous anti-tumor therapy has not recovered (>NCI-CITCAE 5.0 level 2), neurotoxic reaction level 2, except hair loss; 4. Patients should use strong CYP3A4 inhibitors (except drugs permitted in Section 6.8), inducers or sensitive substrates and sensitive substrates of CYP2B6, CYP2C8, CYP2C6 at the same time; 5. Patients take drugs (mainly Ia, Ic, class III anti-arrhythmia drugs) that will prolong the QTc interval or have risk factors for extending the QTc interval; 6. Difficulty in swallowing, or having an absorbance syndrome, or other medical conditions that prevent the absorption of drugs through the intestinal tract, or affect the absorption of FCN-098; 7. Cardiac function and disease meet one of the following conditions: screening period in research center 3 times of 12 lead ECG measurement, according to the instrument of QTc formula for calculating the average three times, QTc>470 ms for female and QTc>450 ms for male. continue uncontrolled hypertension, systolic blood pressure under antihypertensive treatment >150 mmHg, and/or diastolic pressure >100 mmHg. the American New York Heart Association (New York Heart Association, NYHA) classification of grade 3 or more congestive Heart failure; Arrhythmias of clinical significance, including but not limited to complete left bundle branch conduction anomaly, degree II atrioventricular block; within 6 months prior to screening of a history of heart attack or a stroke within three months. 8. Active bacterial, fungal or viral infections of clinical significance, including hepatitis B (hepatitis B virus surface antigen-positive with HBV DNA exceeding 1000 IU/ml or meet the criteria for active hepatitis B infection) or hepatitis C (HCV RNA positive), human immunodeficiency virus infection (HIV positive); 9. Suffered from a malignant tumor other than the selected indications in the past 5 years (other than fully treated cervical carcinoma in situ, non-melanoma basal cell or squamous epithelial cell skin cancer, local prostate cancer after radical operation, ductal carcinoma in situ after radical operation); 10. Women who are pregnant or breastfeeding. Any patient who becomes pregnant during the trial should withdraw from the study; 11.Rule out any situation that is not suitable for entry into the group. For example, it may cause confusion in research results, interfere with patients' participation in research procedures, or have a history of other diseases, treatments, or laboratory abnormalities, or current evidence that does not meet the clinical benefits of participating in the research. (Such as uncontrollable diabetes, active or uncontrollable infection, etc.).
