FMT+Immunotherapy+Chemotherapy As First-line Treatment for Driver-gene Negative Advanced NSCLC

Recruiting now · Phase 2

Conditions studied: Non-small Cell Lung Cancer

In brief

This study plans to reconstruct intestinal microecology through fecal microbiota transplantation (FMT), and combine with standard first-line therapy to enhance the anti-tumor immune effect at the same time, thereby extending the progression-free survival of patients and improving the prognosis of patients.

• Age 18-80 years old (when signing the informed consent form);
• Patients with histologically or cytologically proven locally advanced (stage IIIB/IIIC), metastatic, or recurrent (stage IV) NSCLC who are inoperable and unable to receive radical concurrent chemoradiotherapy, according to the International Association for the Study of Lung Cancer and the American Joint Committee on Cancer Classification, 8th Edition TNM Classification of Lung cancer;
• Have not received systemic intravenous anti-tumor therapy before, and the driver gene is negative;
• PD-L1 expression < 50%;
• According to the solid tumor efficacy evaluation criteria (RECIST version 1.1), there is at least one radiographically measurable lesion; That is, in CT or MRI detection, the longest diameter of a single lesion was ≥10mm, or the pathological enlargement of a single lymph node was ≥15mm.
• The physical status score of Eastern Tumor Collaboration Group (ECOG) was 0-1;
• Expected survival > 3 months;
• Have adequate organ and bone marrow function, laboratory examination within 7 days prior to enrollment meets the following requirements (no blood components, cell growth factors, albumin or other corrective drugs are allowed within 14 days prior to obtaining laboratory examination), as follows: 1) Blood routine: absolute neutrophil count (ANC) ≥1.5×10 9/L, platelet (PLT) ≥75×10 9/L, hemoglobin (HGB) ≥90 g/L (no blood transfusion or erythropoietin dependence within 14 days); 2) Liver function: serum total bilirubin (TBIL) ≤2 times the upper limit of normal (ULN); Alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) ≤ 5x ULN, serum albumin ≥28 g/L; alkaline phosphatase (ALP) ≤5×ULN; 3) Renal function: serum creatinine (Cr) ≤1.5×ULN, or creatinine clearance ≥50 mL/min (using the standard Cockcroft-Gault formula) : Urine routine results showed urinary protein < 2+; For patients with urine protein ≥2+ at baseline, 24-hour urine collection and 24-hour urine protein quantification < 1g should be performed. 4) Coagulation function: International standardized ratio (INR) or prothrombin time (PT) ≤1.5 times ULN; If the subject is receiving anticoagulant therapy, as long as the INR is within the intended range of anticoagulant drug use.
• For female subjects of reproductive age, a urine or serum pregnancy test should be performed and the result is negative 3 days prior to receiving the initial study drug administration;
• Subjects and their sexual partners are required to use a medically approved contraceptive method (such as an intrauterine device (IUD), contraceptive pill, or condom) during the study treatment period and for 6 months after the end of the study treatment period.

You may not qualify if…

• Currently participating in an interventional clinical study or receiving another investigational drug or investigational device within 4 weeks prior to initial dosing;
