Overview

To explore the efficacy and safety of neoadjuvant furmonertinib combined with bevacizumab in the treatment of resectable and potentially resectable stage III-IVA EGFR mutation-positive lung adenocarcinoma.

The best treatment for lung cancer is still radical resection, which is indicated for stage I-II and some stage III patients, but surgery is only suitable for 20-25% of NSCLC patients. Furmonertinib is a third-generation TKI drug. Compared with first and second-generation TKI drugs, it has good benefits in the Chinese population, patients with brain metastases, and patients with 19del/L858R mutation, with better and longer-lasting effects, and can significantly improve the progression-free survival of patients. Neoadjuvant therapy can shrink the tumor, increase the rate of complete surgical resection, remove micrometastases, and reduce the risk of recurrence. Cases of patients with locally advanced (IIIA-N2) NSCLC have been reported with neoadjuvant TKI therapy, and it has been found that neoadjuvant TKI therapy can downgrade or even complete tumor remission. However, for locally advanced potentially resectable, or EGFR mutation-positive NSCLC patients with single-organ metastasis, the efficacy of third-generation EGFR-TKI combined with VEFGR inhibitor combined with targeted therapy after induction and surgery is still unclear. Limited clinical research data suggest that this new treatment mode (induction therapy-surgery-adjuvant therapy) can significantly improve the progression-free survival of patients. However, the overall survival rate under the new treatment mode and the promotion of clinical work urgently need higher-level clinical evidence to support clinical decision-making.

Outcomes

Primary Outcomes

Objective response rate (ORR)

It refers to the proportion of patients who have had a complete response or partial response (according to RECIST1.1) as confirmed by CT evaluation after 3 weeks in all patients who have completed the neoadjuvant therapy. Only patients with measurable lesions at baseline will be analyzed.

Time frame: up to 21 months

Secondary Outcomes

Disease-free survival (DFS)

It refers to the time from radical surgery to relapse or death of a participant due to disease progression. In the case of a patient who still survives at the time of analysis, the latest evaluation date will be used for interpolation (censoring).

Time frame: up to 54 months

Overall survival (OS)

It is defined as the time from enrollment to death of participant due to any cause. In the case of a patient who still survives at the time of analysis, the date of last contact will be taken as the censoring date. In the event of a patient with the survival status unknown, the date when the patient is last known to be alive will be used for interpolation (censoring).

Time frame: up to 60 months

Health related quality of life (HRQol)

The assessment is made according to the Quality of Life Scale for Lung Cancer Patients (EORTC-QLQ-C30 \& LC13, Version 3). EORTC's QLQ-C30 \& LC13 (V3.0) is a core scale for lung cancer patients, with a total of 43 items. Among them, Item 29 and 30 are divided into seven grades, which are assigned with 1 to 7 scores according to the answer options. The other items are divided into 4 grades: Not at All, A Little, Quite a Bit, and Very Much, assigned with 1 to 4 scores respectively. The higher score, the worse quality.

Time frame: up to 6 months

Progression-free survival (PFS)

It refers to the time from the first administration of SHR1316 in this study to the disease progression or death (including any cause of death in the case of no progression) , regardless of whether the patient exits from the treatment or receives other anti-cancer treatment before progression.

Time frame: up to 54 months

R0 resection

It is defined as the proportion of patients with negative surgical margin and no residual found under microscope after resection in all patients who have completed the treatment.

Time frame: up to 24 months

Pathological downstaging rate

It is defined as the proportion of patients who have completed the 8-week treatment with afatinib before operation and have achieved a T stage downing of the tumor as confirmed by CT evaluation after 3 weeks in all patients who have completed the treatment.

Time frame: up to 24 months

Treatment-related adverse events (AEs)

It refers to the number of adverse events related to furmonertinib plus bevacizumab therapy or furmonertinib monotherapy as evaluated according to CTCAE v4.0.

Time frame: up to 6 months

Pathological complete response rate (pCR)

It refers to the number of cases with no residual invasive cancer in the primary tumor and lymph node HE staining accounted for the proportion of all patients who completed the treatment.
