What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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 inductive/neoadjuvant therapy. Only patients with measurable lesions at baseline will be analyzed.	up to 16 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Major pathologic response (MPR)	MPR is defined as the proportion of participants who have achieved major pathologic response (on routine hematoxylin and eosin staining, tumors with no more than 10% viable tumor cells) in all participants who have completed the neoadjuvant therapy before surgery.	up to 5 months
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).	up to 60 months
Progression-free survival (PFS)	It refers to the time from the first administration of TQB2450 in this study to the disease progression or death (including any cause of death in the case of no progression) as recorded in CRF, regardless of whether the patient exits from the treatment or receives other anti-cancer treatment before progression.	up to 60 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.	up to 63 months
Safety: frequency of severe adverse events	The frequency of severe adverse events from the participants enrolling to 90 days after the last drug administration or 30 days after surgery or new anti-cancer therapy, which comes first.	up to 18 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.	up to 12 months
Event-free survival (EFS)	It refers to the time from the first administration of TQB2450 in this study to the disease progression or death (including any cause of death in the case of no progression) as recorded in CRF, regardless of whether the patient exits from the treatment or receives other anti-cancer treatment before progression.	up to 60 months
