Sufficient organ and bone marrow function (without receiving blood transfusion, erythropoietin, recombinant human thrombopoietin or colony stimulating factor therapy, renal replacement therapy, etc. within 7 days before the examination, the laboratory examination meets the following conditions Regulations): a) Blood routine: absolute neutrophil count (ANC) > or = 1.0×10^9/L; platelet count (PLT) > or = 75×10^9/L; hemoglobin concentration > or = 9.0 g/dl; b) Liver function: AST and ALT < or = 2.5×upper limit of normal (ULN), TBIL< or = 1.5×ULN; for patients with liver metastasis or primary biliary tract tumors, ALT and AST < or = 5×ULN; for liver cancer, liver metastasis or Gil Patients with Gilbert's syndrome, TBIL < or = 3×ULN; c) Renal function: serum creatinine (Cr) < or = 1.5×ULN or creatinine clearance > or = 40 ml/min (using the standard Cockcroft-Gault formula); d) Coagulation function: International normalized ratio (INR), activated partial thromboplastin time (APTT) and prothrombin time (PT) < or = 1.5×ULN;

7. Able to understand and voluntarily sign an informed consent form, and be able to comply with the visit and related procedures stipulated in the plan

Exclusion Criteria:

1. There are known major driver gene changes other than RET. For example, NSCLC carrying targeted mutations such as EGFR, ALK, ROS1 or BRAF; colorectal cancer carrying mutations such as oncogenic KRAS, NRAS or BRAF. If the patient has a co-mutation, the investigator should discuss with the sponsor whether the patient can be included in the group

2. Symptomatic primary central nervous system (CNS) tumors, brain metastases, leptomeningeal carcinogenesis, or untreated spinal cord compression that the researchers believe require local intervention

3. People with other active malignant tumors (except for non-melanoma skin cancer in situ, cervical cancer in situ and other localized tumors that have been cured and have not recurred within 5 years)

4. Need to use drugs known to be potent inhibitors or inducers of CYP3A4, drugs known to prolong QTc, and the treatment cannot be terminated at least 14 days before the study drug is administered

5. Received the following anti-tumor treatments: a) The previous anti-tumor drug treatment (except immunotherapy or other antibody therapy) is less than 14 days or 5 half-lives (whichever is longer) from the first treatment with study drug; b) In Those who have received any immunotherapy or other antibody treatment within 28 days before the first study drug administration; c) Those who have received more than 30% of bone marrow radiation or wide-range radiotherapy within 28 days before the first study drug treatment (the patients receiving palliative radiotherapy are the first Within 7 days before receiving study drug treatment)

6. Received major surgical operations within 28 days before receiving the first study drug treatment (excluding operations such as central venous catheter placement, tumor biopsy, and gastric tube placement)

7. Those who have received other clinical trial drug treatment within 28 days before receiving the first study drug treatment

8. Any original symptoms that may interfere with the results of the study, including: any unrecovered toxicity above grade 1 of the CTCAE related to previous anti-tumor therapy (hair loss and grade 2 neuropathy related to previous platinum-based drug treatment, etc.) Except for chronic toxicity judged by the person

9. Patients with clinically active interstitial lung disease, active pneumonia, and radiation pneumonia requiring treatment, or those who have been found or suspected of having such diseases during the screening period

10. Poorly controlled pleural effusion, abdominal effusion, or pericardial effusion after intervention (such as drainage)

11. Any serious and/or uncontrolled comorbidities that may prevent the patient from participating in the study

12. Those who are known to be allergic to any component in the study drug prescription

13. Clinically significant active malabsorption syndrome or other diseases that may affect study drug administration and gastrointestinal absorption

14. Active hepatitis B (hepatitis B surface antigen is positive and HBV-DNA is higher than the upper limit of normal detection) or hepatitis C (hepatitis C antibody is positive and HCV-RNA is higher than the upper limit of normal detection); Human immunodeficiency virus (HIV) examination Positive or known acquired immunodeficiency syndrome (AIDS); Treponema pallidum antibody test is positive

15. Pregnant or breastfeeding women, fertility patients (regardless of male and female) who cannot take effective medical contraceptive measures during the study period and within 6 months after the last administration

16. Other situations where the researcher thinks it is inappropriate to participate in this research
