Almonertinib Plus Microwave Ablation in Advanced Non-small Cell Lung Cancer

Study Overview
=================
Brief Summary
-----------------
Almonertinib, as a third-generation EGFR-TKI, has been used for the treatment of advanced non small cell lung cancer. How to improve the progression free survival in advance was a challenge. Our previous study showed that first-line EGFR-TKIs plus microwave ablation had PFS survival advantage versus EGFR-TKIs alone. So we conducted this prospective study to verify the efficacy and safety of the combination in a randomized, controlled, phase II clinical trial.

Almonertinib, as a third-generation EGFR-TKI, has been used for the treatment of advanced non small cell lung cancer. How to improve the progression free survival in advance was a challenge. Our previous study showed that first-line EGFR-TKIs plus microwave ablation had PFS survival advantage versus EGFR-TKIs alone. So we conducted this prospective study to verify the efficacy and safety of the combination in a randomized, controlled, phase II clinical trial. Patients were assigned into two groups.In the experiment group, patients were treated with both Almonertinib and microwave ablation. In the control group, patients were treated with Almonertinib alone. The primary end point was progression free survival. Second endpoints included overall survival and safety.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Almonertinib plus Microwave ablation group<br>Patients in the group were treated with both targeted therapy and microwave ablation. Patients were treated with Almonertinib with the dose of 110mg once daily firstly. When the best response achieved, microwave ablation was conducted in the primary tumors, and then followed by Almonertinib treatments. | Combination Product: Almonertinib plus microwave ablation<br>* Patients were treated with almonertinib firstly.When almonertinib achieved the maximal response, microwave ablation was conducted on the primary lung tumors.<br>* Other names: Microwave ablation;|
| Active Comparator: Almonertinib group<br>Patients in the group were treated with Almonertinib with the dose of 110mg once daily until disease progression, death or intolerable adverse events. | Combination Product: Almonertinib plus microwave ablation<br>* Patients were treated with almonertinib firstly.When almonertinib achieved the maximal response, microwave ablation was conducted on the primary lung tumors.<br>* Other names: Microwave ablation;|
