Active clinical trials for "Lung Neoplasms"

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.

Various driver gene mutations have been identified in lung cancer. Among them, human epidermal growth factor 2 (HER2) was identified in approximately 2% of non-small-cell lung cancers. Pyrotinib is an oral tyrosine kinase inhibitor targeting both HER-1 and HER-2 receptors. This is a prospective, single-arm, open-label phase II study, designed to evaluate the efficacy and safety of pyrotinib combined with thalidomide in advanced non-small-cell lung cancer patients with HER2 exon 20 insertions.

Neoantigen vaccine is a new field of research in tumor immunotherapy, and some studies have been conducted with success on Melanoma and glioblastoma. Nearly 80% of lung cancers are diagnosed in an advanced stage (IIIB, and IV) and EGFR mutant non-small cell lung cancer will be resistant after targeted drug treatment. Neoantigen vaccine is a new treatment method for lung cancer, especially for patients with drug resistance.

The purpose of this study is to to explore the efficacy and safety of PD-1 immune check point inhibitor, sintilimab, in biomarker-selected subjects with advanced or metastatic Non-small Cell Lung Cancer who have failed from standard front-line treatment.

Almonertinib Plus Pemetrexed and Carboplatin Versus Almonertinib Alone in Advanced NSCLC With EGFR T790M After First- or Second-generation TKIs Therapy: a Randomized, Controlled, Open-label, Phase 2 Study

This Study is To Evaluate the Efficacy and Safety of Anlotinib Hydrochloride Capsule Combined with Allitinib Tablets in First-line Treatment of Advanced no-squamous and No-small Cell Lung Cancer with Epidermal Growth Factor Receptor Mutation.

This research study is being conducted to assess the safety and feasibility of using a newly developed bronchoscopic light delivery method of photodynamic therapy to treat subjects with solid tumors in peripheral lung, who are inoperable or refused surgery.

This study is a clinical study on the safety, efficacy and I phase of single center, single arm, open-dose climbing, intravenous infusion of Anti- Epidermal growth factor receptor(EGFR) Chimeric Antigen Receptor(CAR) T cells modified by C-X-C Chemokine receptor type 5(CXCR 5) in patients with advanced adult non-small cell lung cancer(NSCLC).

Leptomeningeal metastasis (LM) is a devastating and terminal complication of advanced non-small-cell lung cancer (NSCLC), especially in patients harboring epidermal growth factor receptor (EGFR) mutations. Osimertinib is an oral,third-generation, irreversible epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) that selectively inhibits both EGFR-TKI-sensitizing and EGFR T790M resistance mutations .AURA I/II study and other preclinical study suggested that Osimertinib exhibited a better blood-brain barrier(BBB) penetration than the other EGFR-TKIs (gefitinib, erlotinib, or afatinib).The BLOOM 、AURA and FLURA study demonstrated that osimertinib showed encouraging activity and manageable tolerability in pretreated EGFR-mutant NSCLC patients with LM. Bevacizumab is a monoclonal antibody against vascular endothelial growth factor (VEGF). Animal study and autopsy specimens showed that VEGF is an essential factor in LM. Recently study showed EGFR-TKIs plus bevacizumab prolonged PFS and OS in patients with EGFR-mutant NSCLC and multiple brain mteastasis when compared with EGFR-TKIs alone. Howerver osimertinib combined with bevacizumab could benefit patients with LM from EGFR- mutant NSCLC remains undetermined. Therefore, the purpose of the study is to evaluate the safety and efficacy of osimertinib combined with bevacizumab for EGFR- mutant non-small cell lung cancer with leptomeningeal metastasis

Through prospective, randomized and controlled clinical study, patients with early lung cancer who do not need lymph node dissection according to routine diagnosis and treatment were selected. The feasibility and safety of preserving vagal pulmonary branch intact during minimally invasive surgery were compared with traditional minimally invasive surgery, and the feasibility and safety of preserving vagal pulmonary branch intact during minimally invasive surgery were clarified. The effect of preserving pulmonary branches of vagus nerve in minimally invasive surgery of early lung cancer on preventing or reducing pulmonary complications after operation was evaluated by main observation indexes (incidence of pulmonary complications) and secondary evaluation indexes. It will provide a safer, simpler and more effective new technology for patients with early lung cancer undergoing minimally invasive surgery, and provide a basis for the popularization of this new technology.
