Filter by:This is a Phase IIb, multicohort, open-label multicenter study of combination immunotherapies in patients who have previously received treatment with PD-1/PD-L1 immune checkpoint inhibitors. All patients in Cohorts 1-4 will receive the combination treatment of PD-1/PD-L1 checkpoint inhibitor plus N-803 for up to 17 cycles. Each cycle is six weeks in duration. Some patients who experience disease progression while on study in Cohorts 1-4 may roll over into Cohort 5 and receive combination therapy with a PD-1/PD-L1 checkpoint inhibitor, N-803, and PD-L1 t-haNK cellular therapy for up to an additional 17 cycles. Each cycle is six weeks in duration. All patients will receive N-803 once every 3 weeks. Patients will also receive the same checkpoint inhibitor that they received during their previous therapy. Radiologic evaluation will occur at the end of each treatment cycle. Treatment will continue for up to 2 years, or until the patient experiences confirmed progressive disease or unacceptable toxicity, withdraws consent, or if the Investigator feels it is no longer in the patient's best interest to continue treatment. Patients will be followed for disease progression, post-therapies, and survival through 24 months past administration of the first dose of study drug.
Detection of Volatile Organic Compounds (VOC) directly from tissue by headspace analysis (skin, surgery material, other tissue) and exhaled breath is feasible using affordable user-friendly novel nano-chemo sensors that can accurately be used for screening and monitoring purpose
Based upon RTOG 9904, this study is to investigate the role of preoperative chemo and chemoradiation for locally advanced gastric cancer.
Fruquintinib once daily in 4 weeks treatment cycle (three weeks on and one week off) in combination with Paclitaxel 80mg/㎡（day1, 8, 15 of 4 weeks cycle) was well tolerated and demonstrated encouraging preliminary clinical antitumor activity in patients with advanced GC in ph1b/2 study. This study is aimed to evaluate the efficacy and safety of Fruquintinib in combination with Paclitaxel in the treatment of patients with aGC who have progressed after first line standard chemotherapy.
The study is to investigate the efficacy and safety of apatinib for the first-fine treatment in elderly patients with locally advanced or metastatic adenocarcinoma of stomach or gastroesophageal junction, unable or unwilling to chemotherapy, through progression-free survival (PFS). Apatinib will be given to patients with an efficacy assessment of stable disease (SD), partial response (PR), or complete response (CR) every 2 cycles. Patients were assigned to 500 mg/d apatinib continually until disease progression or intolerable toxicity or patients withdrawal of consent. The dose of apatinib may be decreased to 250 mg/d following the occurrence of a clinically significant adverse event (AE). Treatment will be discontinued if the subject is unable to tolerate a daily dose of 250 mg, and the sample size is about 30 individuals. Tumor tissue samples will be collected from each enrolled subjects before the start of treatment, and detected using next generation sequencing (NGS)-based comprehensive genomic profiling. The potential biomarkers in predicting apatinib efficacy or safety will be explored.
Laparoscopic sentinel lymph node dissection and stomach preserving surgery in early gastric cancer is less invasive method which can increase quality of life. Current stomach preserving surgery after sentinel lymph node dissection produce transmural communication and expose the tumor to the peritoneum during operation. An endoscopic full-thickness resection method with a simple suturing technique that does not expose the gastric mucosa to the peritoneum (non-exposure simple suturing, NESS) was recently developed. This is the pilot study to prove the feasibility of NESS-EFTR with sentinel node navigation in early gastric cancer patients.
Colorectal carcinoma is a heterogeneous disease that is caused by the interaction of genetic and environmental factors. colorectal carcinoma encompasses a complex disease with different molecular pathways and biological characteristics arising from a multi-step process that implicates several genetic and epigenetic events . The multi-step genetic model involves the loss of function of tumor suppressor genes, such as adenomatous polyposis coli (APC), Telomeres could be a promising marker due to the fact that their lengths change in the colorectal polyp-carcinoma sequence . Moreover, telomere length (TL) is altered in blood cells in patients with colorectal carcinoma - These findings could suggest that changes in TL may take place before the development of the tumor . The two main forms of inflammatory bowel disease (IBD), ulcerative colitis (UC) and Crohn's disease (CD) are characterized by chronic intestinal inflammation and risk of progression to colon cancer. One proposed cause of the latter characteristic is chromosome instability, since the rearrangement of genetic material can lead to activation of oncogenes, loss of tumor suppressor genes and other changes that lead to uncontrolled cell growth. Chromosome instability is particularly associated with UC and has been observed in colon epithelial cells and peripheral blood mononuclear cell. Since genomic instability in peripheral blood mononuclear cells (PBMCs) has been used as a biomarker for global cancer risk in a number of diseases, the latter observation suggests the possibility of a chromosome instability syndrome in UC that could affect all tissues. One possible cause of chromosome instability is telomere dysfunction .
Objective: To evaluate the impact and cost-effectiveness of FDG-PET/CT (PET) and diagnostic laparoscopy (DLS) in addition to initial staging by CT and gastroscopy in patients with advanced gastric cancer. Hypothesis: The study hypothesizes that performing DLS and PET for advanced gastric adenocarcinomas results in a reduction in the number of futile gastrectomies performed and a favorable cost-effectiveness. According to the literature, in 27% of patients a futile gastrectomy can be prevented, and the annual cost-reduction is an estimated €916.438. Study design: The study design is a prospective observational study. Study population: The study population consists of patients with a surgically resectable, advanced gastric adenocarcinoma (cT3-4a,N0-3,M0), that are scheduled for treatment with curative intent after initial staging with gastroscopy and CT. Usual care / comparison: Both PET and DLS were recently included in the new Dutch guidelines for the treatment of gastric cancer, as staging modalities for advanced (T3-4) tumors after initial staging. The costs of the study population will be compared to retrospective data of patients who underwent curative surgery (gastrectomy) after initial staging with CT alone. Outcome measures: The primary outcome of this study will be the proportion of patients in whom the PET or DLS lead to a change in treatment strategy. The accuracy of each modality will be analyzed separately. Secondary outcome parameters will be diagnostic performance, morbidity and mortality, quality of life, cost-reduction and cost-effectiveness. Sample size: Based on the expectation that 22% of patients will have a change in treatment strategy, at least 239 patients will be needed for this study to demonstrate that the diagnostic modalities in the new guideline are break-even. Approximately 543 patients will be eligible for the study in 36 months. Cost-effectiveness analysis: A state-of-the-art cost-effectiveness analysis and budget impact analysis will be performed on the additive value of PET and DLS by both prospective and retrospective data collection
This study is designed to evaluate the impact of muscle relaxation during laparoscopic gastrectomy on oncological benefit, especially with obese patients over BMI 25. The primary endpoint is number of harvested lymph node that is critical point regarding quality of surgery in gastric cancer treatment. The secondary endpoint is intraoperative bleeding, surgeons' satisfaction. The patients were randomly assigned to two groups using a computer-generated randomization table : 196 persons - Deep neuromuscular block group (98persons) - Moderate neuromuscular group (98persons)
This phase 2 trial evaluates the benefit of epacadostat plus pembrolizumab in combination to treat patients with gastroesophageal junction or gastric cancer that has spread to other parts of the body and cannot be removed by surgery. Epacadostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as pembrolizumab, may block tumor growth in different ways by targeting certain cells. Giving epacadostat and pembrolizumab may work better in treating patients with gastroesophageal junction or gastric cancer.
