Brief Summary

In recent years, immunotherapy research has made great progress, especially the immunocheckpoint inhibitors represented by anti-pd-1 antibody have shown good efficacy in the treatment of malignant tumors, and some patients can achieve long-term survival. However, despite the encouraging clinical data, only a small number of people have benefited. Therefore, how to further improve the efficacy of immunotherapy and expand the benefit population has become the focus of this field. The applicant was previously published in Oncoimmunology (2017; E1331807) pointed out in the above article: MDSC is a group of immunosuppressive cells, the number of this group of cells in the body of cancer patients is more than normal, its presence affects the proliferation, activation and function of T cells, is one of the important factors affecting the efficacy of immunocheckpoint inhibitors. Therefore, ideal drugs used in combination with immunocheckpoint inhibitors should meet the following conditions: first, they can kill or inactivate tumor cells to release tumor-specific or associated antigens; Second, MDSC and other immunosuppressive cells can be eliminated. Third, the number and function of T cells were not affected. Gemcitabine is a synthetic antimetabolic tumor drug widely used in the treatment of locally advanced or metastatic non-small cell lung cancer. Myelosuppression is the dose - limiting toxicity of gemcitabine, which includes lymphocytopenia. Therefore, if the commonly used clinical dose gemcitabine is used in combination with pd-1 antibody, the effect of pd-1 antibody will be affected due to the reduction of lymphocytes caused by gemcitabine. Therefore, we speculated that the reduced-dose treatment of gemcitabine combined with pd-1 antibody might have synergistic anti-tumor effect on the second-line and above second-line treatment of non-small cell lung cancer with negative driver gene, and the adverse reactions were relatively mild. This study is a phase IV, open, non-randomized, single-arm, single-center study to investigate the safety and efficacy of half-dose gemcitabine combined with pd-1 antibody in second-line and above treatment of non-small cell lung cancer patients with negative driver genes. Fifty subjects will be enrolled in this study. The primary endpoint of the study was ORR, while secondary endpoints included DCR, PFS, and OS.

Study Arms (1)

Low-dose Gemcitabine Combined With nivolumab

EXPERIMENTAL

Bristol-myers squibb (BMS) company's nivolumab injection liquid (trade name: odiwal). Recommended dosage: 3mg/kg, intravenously injected once every 2 weeks for 60 minutes. As long as clinical benefit is observed, continue treatment with this product for up to 6 courses. Gemcitabine hydrochloride injection from eli lilly. Use 50% of the recommended dose, i.e. 500mg/m2, intravenously for 30 minutes. Day 1 and day 8 administration. Depending on the patient's tolerance to gemcitabine, a reduced dose may be considered for each treatment cycle or one treatment cycle. Use for 1 year. If a Ⅲ magnitude of adverse reactions, it is necessary to permanently discontinued.

Drug: Gemcitabine Injectable Product

Interventions

Low dose chemotherapy drug combined with pd-1 antibody, Gemcitabine should be administered at 50% of the recommended dose, i.e. 500mg/m2, for 30 minutes by intravenous drip. Day 1 and day 8 administration.
