Safety and Efficacy of Aumolertinib Combined With Anlotinib as 1st Line Treatment in Advanced Lung Cancer EGFR Mutation With TP53 Co-Mutation

Safety and Efficacy of Aumolertinib Combined With Anlotinib as 1st Line Treatment in Advanced Lung Cancer EGFR Mutation With TP53 Co-Mutation

The goal of this open, single-arm, exploratory phase II clinical study is to exploratory safety and efficacy in 1st line treatment in advanced lung cancer EGFR mutation with TP53 co-mutation. 47 patients are scheduled to be enrolled. Treatment regimen is aumolertinib 110mg p.o QD and Anlotinib 12mg oral for 2 weeks, three weeks a cycle, until disease progression or intolerable adverse reactions or death.

The primary objective of this study was to explore the median PFS of aumolertinib Combined With anlotinib as first-line treatment in advanced lung cancer EGFR mutation with TP53 co-mutation.The secondary objective of this study was to evaluate the ORR, DCR, DOR, OS and safety of aumolertinib Combined With anlotinib as first-line treatment in advanced lung cancer EGFR mutation with TP53 co-mutation. In addition, we also try to explore predictive or prognostic biomarkers (tissue and/or plasma) related to disease treatment response or drug resistance. Analyze the potential biomarkers in the biopsy tissue samples and blood samples after the disease progresses, and explore the possible mechanism of treating drug resistance.

2. Patients with symptomatic brain metastasis at the beginning of treatment (patients with brain metastasis who have received treatment in the past are eligible if asymptomatic brain metastasis lasts for at least 4 weeks when receiving stable dose of drug treatment);
3. . Patients who participated in the intervention tumor clinical trial during the first-line treatment or within the last 30 days before the first-line treatment;
4. History of tracheoesophageal fistula, gastrointestinal perforation or gastrointestinal fistula and intra-abdominal abscess within 6 months before treatment;
5. Suffer from serious cardio-cerebrovascular disease;
6. Subjects who received chest radiotherapy in the lung field within the first 4 weeks, or who have not recovered from radiotherapy-related toxicity. Subjects who received radiotherapy or did not recover from radiotherapy-related toxicity within 2 weeks before randomization for all other anatomical sites;
7. Major surgical treatment was performed within 4 weeks before treatment or planned during the trial period (the researcher judged that there was bleeding risk or wound healing complications);
8. . Have bleeding tendency, high bleeding risk or coagulation dysfunction, including thrombotic disease within 6 months before randomization and/or hemoptysis history within 3 months before randomization (single cough bleeding ≥ 2.5mL)

10. Imaging examination showed that there was evidence of tumor invasion into large vessels, and the tumor had completely approached, surrounded or invaded the lumen of large vessels (such as pulmonary artery or superior vena cava);
11. Subjects with hypertension (systolic blood pressure>160mmHg or diastolic blood pressure>100mmHg) that are still poorly controlled after treatment with two or more antihypertensive drugs in the screening period, and who have a history of hypertensive crisis or hypertensive brain disease in the past;
