Brief Summary

This study is a multi-center, prospective, double-blind randomized controlled clinical trial. The purpose is to evaluate the efficacy and safety of EGFR-TKI on residual GGOs after surgery in patients with multiple primary lung cancers with ground glass nodules. This study is expected to prove that compared with placebo in the control group, EGFR-TKI can significantly reduce the residual GGOs lesions in patients with EGFR-positive multiple primary lung cancers with ground-glass opacity, and bring a higher objective response rate (ORR), thus provides new insights for treatment of these patients.

Detailed Description

Lung cancer is one of the most deadly malignant tumors in the world. It is estimated that 0.2-20% of lung cancer patients have multiple primary lung cancers at the time of diagnosis, and many of them present with multiple ground glass opacities. The surgical method for such multiple lesions depends on their number, anatomical location and size, as well as the age and pulmonary function of the patient. It is easily affected by the subjective judgment of the surgeon. Besides, many of these patients develop multiple lesions that cannot be resected at the same time, and there haven't been established a standard therapy for residual GGO lesions after surgery.

According to the National Comprehensive Cancer Network (NCCN) guidelines, EGFR-TKI is recommended for the adjuvant treatment of stage IB-ⅢA NSCLC with EGFR mutations. However, it is not clear whether EGFR-TKI is effective for multiple primary lung cancers or the residual GGOs after surgical resection of the EGFR mutation positive main cancers. At present, there have been retrospective studies showing that application of EGFR-TKIs targeted therapy can significantly reduce the diameter of residual GGOs after surgery resection of EGFR mutation-positive primary lesions for MPLC patients, and reduce the secondary surgery caused by the progression of the lesion. However, there is no prospective Studies confirming the efficacy and safety of EGFR-TKI on these postoperative residual GGOs lesions.

This study is a multi-center, prospective, double-blind, comparative clinical research. This study plans to enroll 138 patients with multiple primary lung cancers (cTis-T1c, N0, M0) that manifest GGO and cannot be resected at the same time, patients should have undergone surgical resection of the EGFR mutated main lesion, and have no less than 1 GGO lesion remaining after surgery. Eligible patients will be randomly divided into the treatment group (receiving furmonertinib mesilate tablets) or control group (placebo) at a ratio of 1:1. The grouping process was strictly double-blind for both the investigators and subjects. By collecting the relevant data of patients' baseline images, pathology, and follow-up images during treatment, statistical analysis is used to evaluate the effectiveness (response rate, objective remission rate), safety, and relevant influencing factors (including CTR value of the main lesion, number of residual lesions, diameter of the largest residual lesion, higher stage of the main lesion, residual lesion's density, etc.) of EGFR-TKI treatment.

This study is expected to prove that compared with the placebo in the control group, EGFR-TKI can significantly reduce the diameter of residual GGO lesions in patients with EGFR-positive multiple primary lung cancers with ground-glass density, and bring a higher objective response rate (ORR) but did not significantly increase the incidence of adverse effects.

Study Groups

EGFR-TKI Treatment Arm

After randomization, the enrolled patients in this arm should be completely free from the risk of perioperative complications or recovered from the effects of complications, usually no earlier than 4 weeks after surgery but no more than 10 weeks after surgery, before receiving baseline follow-up and starting oral administration of Furmonertinib on the day of baseline follow-up. Patients in the treatment group should take Furmonertinib (80 mg each time) orally on an empty stomach before breakfast once a day. The medicine should be taken about the same time each day, by swallowing the whole tablet with water, without crushing or chewing. Patients should maintain oral administration of Furmonertinib for 6 consecutive months, unless there is disease progression, death, new anti-tumor therapy received or intolerance of investigational drugs.

Group Type: EXPERIMENTAL

furmonertinib

Intervention Type: DRUG

AST2818 is an irreversible and highly selective EGFR inhibitor independently discovered and developed by Allist. It has the potential to become the best-in-class drug in the third-generation EGFR-TKIs. Data from the preclinical studies and the completed clinical studies show that AST2818 has the following advantages: 1) AST2818 has good target selectivity and tissue distribution specificity; 2) The objective response rate of AST2818 for the patients with locally advanced or metastatic NSCLC with EGFR T790M mutation is outstanding, reaching 74.1% in the key registration clinical study; 3) AST2818 has a good safety profile and is well-tolerated; 4) AST2818 and its active metabolites have a superior ability to penetrate the blood-brain barrier, and have a good therapeutic efficacy on brain metastases frequently seen in patients with NSCLC.

Control Arm

After randomization, the enrolled patients in this arm should be completely free from the risk of perioperative complications or recovered from the effects of complications, usually no earlier than 4 weeks after surgery but no more than 10 weeks after surgery, before receiving baseline follow-up and starting oral administration of placebo on the day of baseline follow-up. Patients in the treatment group should take placebo (80 mg each time) orally on an empty stomach before breakfast once a day. The medicine should be taken about the same time each day, by swallowing the whole tablet with water, without crushing or chewing. Patients should maintain oral administration of placebo for 6 consecutive months, unless there is disease progression, death, new anti-tumor therapy received or intolerance of investigational drugs.

Group Type: PLACEBO_COMPARATOR

Placebo

Intervention Type: DRUG

The placebo has the same appearance, weight, and physical and chemical properties as the study drug, and is provided by the researcher to the subjects in control group.
