Neoadjuvant Immunotherapy Plus Chemotherapy for Potentially Resectable Stage IIIA/IIIB Non-Small Cell Lung Cancer

Prior treatment

• Currently participating in the intervention clinical research and treatment, or receiving other drugs or research instruments within 4 weeks before the first administration;
• Previously received the following therapies: anti-PD-1, anti-PD-L1 or anti-PD-L2 drugs or drugs for another stimulation or synergistic inhibition of T cell receptor (such as CTLA-4, OX-40, CD137);
• Received immunomodulatory drugs (thymosin, interferon, interleukin, etc.) within 2 weeks before the first administration, or received major surgical treatment within 3 weeks before the first administration;
• With a history of haemorrhagic disease, any bleeding event with a severe grade of 3 or more in ctcae5.0 occurred within 4 weeks before screening;
• Received solid organ or blood system transplantation;
• There were idiopathic pulmonary fibrosis, organic pneumonia (such as bronchiolitis obliterans), and drug-related pneumonia;
• Patients who need long-term systemic corticosteroid use. Patients with COPD, asthma requiring intermittent use of bronchodilators, inhaled corticosteroids, or local injection of corticosteroids were included.
• Active infection requiring treatment or systemic anti infective drugs used within 1 week before the first administration;

Other illness

• Other malignant tumors were diagnosed within 5 years before administration, excluding radical skin basal cell carcinoma, skin squamous cell carcinoma and / or radical resection of carcinoma in situ. If more than 5 years before the administration of the drug is diagnosed as other malignant tumors or lung cancer, it is necessary to carry out pathological or cytological diagnosis of the recurrent lesions;
• There are clinically uncontrolled active infections, including but not limited to acute pneumonia;
• III-IV and congestive heart failure (New York Heart Association classification), poorly controlled and clinically significant arrhythmias;
• Active autoimmune diseases requiring systemic treatment (e.g., use of disease improving drugs, corticosteroids or immunosuppressants) occurred within 2 years before the first administration. Alternative therapies (such as thyroxine, insulin or corticosteroids in physiological doses for adrenal or pituitary insufficiency) are not considered systemic.
• In the first 6 months of screening, there were arterial thrombosis events, such as cerebrovascular accident (including transient ischemic attack), myocardial infarction, unstable angina, etc;
• Known human immunodeficiency virus (HIV) infection history (i.e. HIV 1 / 2 antibody positive);
• Untreated active hepatitis B;
  • Note: hepatitis B subjects who meet the following criteria also meet the inclusion criteria:
  • Before the first administration, HBV viral load must be less than 1000 copies / ml (200iu / ml). Subjects should receive anti HBV treatment during the whole period of chemotherapy drug treatment to avoid virus reactivation. For subjects with anti HBC +, HBsAg (-), anti HBS (-), and HBV viral load (-), prophylactic anti HBV treatment is not required, but virus reactivation needs to be closely detected.
• Active HCV infected subjects (HCV antibody positive and HCV-RNA level higher than the detection limit)
• Those who have a history of abuse of psychotropic substances and are unable to give up or have mental disorders;

Lab values

• It is known to have allergic reactions to PD-1 monoclonal antibody, albumin paclitaxel, carboplatin active ingredients and / or any excipients;
• For female subjects: they should be surgical sterilization, postmenopausal patients, or agree to use a medically recognized contraceptive measure during the study treatment period and within 6 months after the end of the study treatment period; the serum or urine pregnancy test must be negative within 7 days before the study is enrolled in the group, and must be non lactation period. Male subjects: patients who should be sterilized surgically or who agree to use a medically approved contraceptive method during the study and within 6 months after the end of the study.
• Inoculate the live vaccine within 30 days before the first administration; Note: it is allowed to receive the injection inactivated virus vaccine for seasonal influenza; however, it is not allowed to accept the live attenuated influenza vaccine for intranasal medication.
  • There are medical history, disease, treatment or laboratory abnormal results that may interfere with the test results, prevent the subjects from participating in the whole process of the study, or the researchers think that participating in the study is not in the best interests of the subjects.

Other

• There are mixed small cell carcinoma and sarcoma in histology;
• Uncontrollable or symptomatic hypercalcemia;
• Long term unhealed wound or incomplete union fracture;

• Asian male or female patients: 18-75 years old;
• ECoG physical condition score: 0-2;
• Histologic examination confirmed that the potential resectable stage IIIA/IIIB non-small cell lung cancer (T4 or N2 according to the TNM staging standard of AJCC 8th Edition);
• Estimated survival time ≥ 12 weeks;
• No systemic anti-tumor therapy has been received before. The function of main organs is normal, that is to say, the relevant examination indexes within 14 days before randomization meet the following requirements:
  • 1\) Blood routine examination:
• Hemoglobin ≥ 90 g / L (no blood transfusion within 14 days); b) Neutrophil count ≥ 1.5 × 109 / L; c) Platelet count ≥ 100 × 109 / L;
  • 2\) Biochemical examination:
• Total bilirubin ≤ 1.5 × ULN (upper limit of normal value); b) ALT or AST ≤ 2.5 × ULN; ALT or AST ≤ 5 × ULN in case of liver metastasis; c) Serum creatinine \< 1.5 times of the upper limit of normal value; endogenous creatinine clearance ≥ 50 ml / min (Cockcroft Gault formula);
  • 3\) Routine coagulation examination:
• INR or PT ≤ 1.5 x ULN.
• APTT ≤ 1.5 x ULN.
  • 4\) Left ventricular ejection fraction (LVEF) ≥ 50%.
  • 7\. Pregnant women of childbearing age must carry out pregnancy test (serum or urine) within 7 days before entering the group, and the result is negative, and they are willing to use appropriate methods of contraception during the test and within 8 weeks after the last administration of the test drug. For men, it is necessary to agree to use appropriate methods of contraception or sterilization after operation during the trial period and within 8 weeks after the last administration of the test drug;
  • 8\. Good compliance, family members agree to cooperate to receive survival follow-up;
