A Study to Prospectively Validate Blood Markers Associated With Differences in Efficacy of Neoadjuvant Therapy for NSCLC

Not yet recruiting

• Conditions: Non-small Cell Lung Cancer
• Interventions: Drug: Chemotherapy only; Drug: Chemotherapy combined with immunotherapy

• Registration Number: NCT06503042
• Lead Sponsor: Tang-Du Hospital

Brief Summary

This study utilized a prospective cohort design. It is proposed to analyze the serum of NSCLC patients treated with chemotherapy combined with immunotherapy, and chemotherapy alone, starting from liquid biopsy technique and combining with proteomic methods. By comparing the differences in serum proteins between the two groups of patients before treatment, we will validate the targets related to efficacy and AE events identified in a previous retrospective study, further explore their associations with patients' clinical outcomes and AE events, and establish a clinical prediction model to guide and improve the current treatment of NSCLC.

3. Have not received any prior systemic anti-tumor therapy or local radiotherapy for NSCLC

4. Have adequate organ and bone marrow function, and the laboratory examination values within 14 days prior to enrollment meet the following requirements (no blood components, cell growth factors, albumin and other intravenous or subcutaneously administered drugs to correct hematological or liver and kidney dysfunction were allowed within the first 14 days of obtaining laboratory tests), as follows:

   ①Hematological function was sufficient, defined as absolute neutrophil count ≥ 1.5 × 109 / L, platelet count ≥ 100 × 109 / L, hemoglobin ≥ 100g / L;

   ②Full liver function, defined as total bilirubin level ≤ 1.5 × ULN, AST and ALT level ≤ 2.5 × ULN, albumin (ALB) ≥ 35g / L;

   • Renal function was sufficient, serum creatinine (Scr) ≤ 1.5 × ULN, creatinine clearance rate (CrCl) ≥ 60mL / min (calculated by Cockcroft / Gault formula) and urine routine test results showed that urinary protein (UPRO) < 2 + or 24-hour urinary protein < 1g;

     • The international normalized ratio (INR) ≤ 1.5 × ULN, and prothrombin time (PT) or activated partial thromboplastin time (APTT) ≤ 1.5 × ULN within 7 days before treatment;

5. For women of childbearing age, urine or serum pregnancy tests were negative for at least seven days prior to the first study drug administration. If the urine pregnancy test is positive, a blood pregnancy test is required;

6. If there is a risk of conception, male and female patients need to use high-efficiency contraception (i.e., the method with an annual failure rate of less than 1 %) and continue until at least 180 days after discontinuation of the trial; Note: If abstinence is the normal lifestyle and preferred contraceptive method of the subjects, abstinence can be accepted as a contraceptive method.

Exclusion Criteria

1. Pathological examination showed that small cell carcinoma, neuroendocrine carcinoma, sarcoma, lymphoepithelioma-like carcinoma, salivary gland tumor and mesenchymal tumor components

2. Tumor invasion of the diaphragm, mediastinum, heart, pericardium, large blood vessels (such as aorta), esophagus, vertebral body

3. pulmonary sulcus tumor

4. Contralateral lung nodules, it need biopsy if clinically suspected

5. Subjects with confirmed or suspected brain metastases

6. Participation in an interventional clinical study or treatment with another investigational drug or investigational device within 4 weeks prior to enrollment

7. Previous use of anti-PD-1, anti-PD-L1, anti-programmed death receptor ligand 2 (PD-L2) or anti-cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) drugs or any other drugs acting on T cell co-stimulation or immune checkpoint pathways (such as OX40, CD137, etc.) and adoptive cellular immunotherapy

8. Received immunomodulatory drugs (including thymidine, interferon, interleukins, etc.) within the first 4 weeks of enrollment

9. Live attenuated vaccine within the first 4 weeks of enrollment (or plan to receive live attenuated vaccine during the study period). Note: Inactivated seasonal influenza vaccine is permitted, but live attenuated influenza vaccine is not permitted

10. Requires prolonged systemic glucocorticoid use and has received any other form of immunosuppressive therapy within 7 days prior to enrollment Note: Nasal spray, inhalation, or other topical glucocorticoid or physiologic doses of systemic glucocorticoid (≤ 10 mg/day of prednisone or equivalent) are permitted or are used for pretreatment (e.g., for prevention of contrast allergy).

11. History of non-infectious pneumonia requiring glucocorticoid therapy within 1 year prior to enrollment or current interstitial lung disease (≥ grade 2)
