a clinical study of the combination of anlotinib and aumolertinib in the first-line treatment of advanced nsclc with egfr 21l858r mutation

Conditions: Non-Small Cell Lung Cancer With Mutation in Epidermal Growth Factor Receptor

Summary: this study is a prospective, multicenter, single arm clinical study. thirty subjects who will have been diagnosed with locally advanced or metastatic non-small cell lung cancer with egfr 21l858r mutation detected in lung cancer tissue or peripheral blood will be recruited and treated with anlotinib and aumolertinib. the efficacy will be evaluated according to the solid tumor efficacy evaluation standard (recist 1.1), and evaluated every 6 to 8 weeks. the survival status and adverse reactions of the subjects will be recorded. the study will be terminated when the subjects experience disease progression or intolerable drug toxicity, or the subjects withdraw their informed consent. the main purpose of the study is to observe the efficacy and safety of the combined treatment regimen in such subjects. the primary endpoint of the study is median progression free survival (mpfs); the secondary study endpoints are objective response rate (orr), disease control rate (dcr), median overall survival time (mos), and safety.


Eligibility criteria:
inclusion criteria: * 1) the patient voluntarily participated in this study and signed an informed consent form; 2) age\>18 years old, both male and female; 3) advanced stage unresectable or metastatic nsclc (stage iiib, iiic, or iv) confirmed by histology or cytology, with the presence of egfr 21 exon l858r mutation in the driving gene; 4) according to the criteria for evaluating the efficacy of solid tumors (recist 1.1), at least one measurable lesion is used as the target lesion; 5) the eastern cancer collaborative group's physical state score (ecog ps) is 0 to 3 points; 6) expected survival time is more than 3 months; 7) newly treated patients who have not received systematic anti-tumor treatment in the past, including radiotherapy and chemotherapy, targeted and immunotherapy; 8) the main organ function meets the following standards within 7 days before treatment:(1) blood routine examination standard (without blood transfusion within 14 days): ① hemoglobin (hb) ≥ 90g/l; ② absolute value of neutrophils (anc) ≥ 1.5 × 109/l; ③ platelet (plt) ≥ 80 × 109/l.(2) biochemical examination should meet the following standards: ① total bilirubin (tbil) ≤ 1.5 times the upper limit of normal value (uln); ② alanine aminotransferase (alt) and aspartate aminotransferase ast ≤ 2.5uln, if accompanied by liver metastasis, alt and ast ≤ 5uln; ③ serum creatinine (cr) ≤ 1.5uln or creatinine clearance rate (ccr) ≥ 60ml/min. exclusion criteria: 1. mixed nsclc containing other pathological components; 2. poor blood pressure control (systolic blood pressure ≥ 150mmhg, diastolic blood pressure ≥ 100mmhg); 3. imaging shows that the tumor invades important blood vessels, or the researcher determines that the tumor is highly likely to invade important blood vessels and cause fatal massive bleeding during subsequent studies; 4. have experienced arteriovenous thrombosis events within 6 months, such as cerebrovascular accidents, deep venous thrombosis, and pulmonary embolism in patients; 5. patients with combined factors that affect oral medication, such as difficulty swallowing, gastrointestinal resection, chronic diarrhea, or intestinal obstruction; 6. patients with symptomatic brain metastases; 7. patients with severe and/or uncontrollable diseases, such as myocardial infarction, unstable angina, congestive heart failure, and severe uncontrollable arrhythmias within 6 months prior to enrollment; 8. active or uncontrolled severe infections; 9. severe liver dysfunction, cirrhosis, acute or chronic active hepatitis; 10. the urine routine results showed that the urine protein level was ≥++, and the 24-hour urine protein quantitative detection result was\>1.0g; 11. active pulmonary tuberculosis; 12. pregnant or lactating women; 13. according to the judgement of the researchers, the subjects may have other factors that may cause the study to be terminated midway, such as other serious illnesses (including mental illness) requiring concurrent treatment, serious laboratory test abnormalities, and accompanying family and social factors, which may affect the safety of the subjects or the collection of data and samples.
