• only for part2 : A. Patients with initial treatment, refusing or intolerant of standard treatment, PD-L1 (IHC 22C3) TPS ≥ 1%; B. Stage IIIB-IV patients with disease progression after previous standard treatment, who intend to receive immune monotherapy, can be enrolled regardless of the results of PD-L1; C. Stage II-III NSCLC patients after radical surgery, postoperative adjuvant chemotherapy (if necessary) has been completed, and PD-L1 (IHC 22c3) TPS is ≥ 1%, intend to receive adjuvant immunotherapy.
• tumor biopsy tissue samples can be provided for tumor neoantigen detection;
• ECOG (Eastern Cooperative Oncology Group) score of 0 \~ 1 in general condition;
• expected survival time of more than 3 months;
• patients have at least one measurable tumor lesion according to Response Evaluation Criteria in Solid Tumors (RECISTv1.1), the longest diameter at baseline is ≥ 10 mm (if lymph nodes, the short diameter is ≥ 15 mm);
• patients shall have sufficient bone marrow reserve function, and have no liver and kidney coagulation dysfunction, and laboratory test values shall meet the following conditions:
• absolute neutrophil count > 1.5 × 10/L, And white blood cell count > 3 × 10/L;
• platelet count > 80 × 10/L;
• hemoglobin > 90 g/L;
• serum creatinine < 1.5 × upper limit of normal (ULN) and creatinine clearance calculated by Cockroft-Gault formula > 30 mL/min;
• if there is no confirmed liver metastasis, AST, ALT < 2.5 × ULN; if there is confirmed liver metastasis, AST, ALT < 5 × ULN;
• if there is no liver metastasis, total bilirubin < 1.5 × ULN; if there is liver metastasis or Gilbert 's syndrome (hyperindirect bilirubinemia), total bilirubin < 3 × ULN;
• international normalized ratio (INR) < 1.5, and activated partial thromboplastin time (APTT) < 1.5 × ULN;
• tumor tissue gene detection suggests that one or more vaccines contain positive tumor neoantigen expression;
• patients do not have brain metastasis (except asymptomatic or stable brain metastasis after treatment for more than four weeks);
• Any adverse reactions caused by previous treatment must have recovered to grade 0-1 (except alopecia and vitiligo) within 4 weeks before the first dose of study drug;
• Patients voluntarily signed informed consent and expected compliance.

You may not qualify if…

• Those meeting any of the following conditions may not be included.
• Known or suspected hypersensitivity to the ingredients of the study drug or its analogues;
• Only for Part 2: adverse reactions of grade ≥3 occurred after using ICIs in the past; except maculopapules /itching and reactive cutaneous capillary hyperplasia (RCCEP), there is no need to stop ICIs in hypothyroidism. Or those who are at high risk of receiving ICI treatment.
• Patients with any other disease or medical condition that is unstable or may affect their safety or study compliance, any serious or uncontrolled systemic disease, including severe heart disease, cerebrovascular disease, uncontrolled diabetes, uncontrolled hypertension, active gastrointestinal ulcers, abnormal immune function, etc.;
• Cardiovascular and cerebrovascular diseases/symptoms/indications that meet any of the following conditions:
• mean resting QTc > 470 ms (corrected QT interval [corrected by Fridericia formula]), mean QTc of 3 ECGs, QT interval measurement should start from QRS complex to the end of T wave);
• any clinically significant resting ECG abnormalities in rhythm, conduction or morphology, such as complete left bundle branch block, grade 2 and 3 heart block, PR interval > 250 ms, etc.;
• any factor that increases the risk of QTc prolongation or arrhythmia, such as heart failure, hypokalemia, congenital long QT syndrome, family history of long QT syndrome, etc. or unexplained sudden death in a first-degree relative under 40 years of age, or any concomitant medication known to prolong the QT interval;
• left ventricular ejection fraction (LVEF) < 50%;
• previous history of decreased myocardial contractility, i.e.Patients who presented with relevant symptoms within 6 months before study drug administration: such as chronic congestive heart failure, pulmonary edema or decreased cardiac ejection fraction;
• patients who had a history of acute or chronic cardiovascular and cerebrovascular diseases and presented with relevant symptoms within 6 months before study drug administration: myocardial infarction, severe or unstable angina pectoris, cerebral infarction, cerebral hemorrhage, or transient ischemic attack;
• . Patients who had an active second primary malignant tumor within 2 years before the first dose of study drug, except for specific cancers to be investigated and locally recurrent cancers that had undergone radical treatment (such as resected basal cell or squamous cell skin cancer, superficial bladder cancer, cervical or breast carcinoma in situ);
• . Patients with uncontrollable malignant third space effusion;
• . For women of childbearing age (postmenopausal women must have been postmenopausal for at least 12 months to be considered of non-childbearing potential), positive serum pregnancy test results within 7 days before the first dose of study drug;

• Other serious, acute or chronic clinical or mental diseases or laboratory abnormalities that may increase the risk of research and drug use, or may interfere with the research results;
