Filter by:This is a Phase 2/3, randomized, open-label study for the treatment of patients with HER2-positive Gastric cancer (GC) or Gastroesophageal Junction (GEJ) cancer conducted in two parts. Part A is a single-arm cohort (Cohort A, 40 to 110 patients) will evaluate safety and efficacy of margetuximab plus retifanlimab. Part B Part 1 has 4 arms (50 patients/arm). Patients will be randomized to margetuximab plus retifanlimab plus chemotherapy, margetuximab plus tebotelimab, plus chemotherapy, margetuximab plus chemotherapy, or trastuzumab plus chemotherapy.
This is a non-randomized multicenter phase 1b clinical trial of the safety and pharmacokinetics, as well as the preliminary efficacy of monotherapy with alofanib, an allosteric fibroblast growth factor receptor 2 inhibitor, in patients with advanced gastric cancer who have exhausted the resource of standard therapy.
IMAGINE is a Phase II, randomized, two-arm, chemotherapy controlled modular trial in subjects with histologically confirmed, resectable gastric cancer (GC) or adenocarcinoma of the gastroesophageal junction (AEG). Up to 22 patients will be included in each arm of the trial.
This prospective, single arm phase II study is designed to evaluate the rate of pathologic complete response of neoadjuvant chemoradiotherapy and neoadjuvant chemotherapy followed by surgery for locally advanced gastric adenocarcinoma
As the survival rate of patients with gastric cancer has increased, there has been a growing interest in interventions that improve postoperative quality of life. Therefore minimally invasive surgery or endoscopic resection has been performed much more frequently. However, adequate lymph node dissection is important as well. The aim of the study is to identify the feasibility of indocyanine green - near infra-red (ICG-NIR) guided sentinel lymph node dissection for the treatment of gastric cancer.
Gastric cancer is one of the common malignant tumors in China, with relatively high incident rate and mortality among the population. Surgery is the conventional treatment option for early and intermediate-stage stage gastric cancer, but postoperative relapse is the major issue. Circulating tumor DNA (ctDNA) is tumor-derived fragmented DNA with an average size of 166 bp, mixed with cell free DNA (cfDNA) of other sources in blood circulation.ctDNA is reflecting the most up-to-date status of tumor genome. Hence, it is considered as a new biomarker for tumor, which can be qualitative, quantitative and used for disease monitoring. The present clinical trial aims to explore the possibility of clinical utility of serum ctDNA as a clinical index to predict the efficacy in immunotherapy for advanced gastric cancer.
This study is to conduct a randomized controlled trial of two kinds of radical gastrectomy for patients with proximal gastric cancer. One is laparoscopic D2 radical total gastrectomy combined with spleen-preserving No.10 lymph node dissection , another one is laparoscopic D2 radical total gastrectomy without clearing the No. 10 lymph nodes of the spleen. We explore the effect of the two procedures on the survival of patients, as well as the surgical complications associated with the two procedures, the number of lymph node dissection, the operation time and the amount of intraoperative blood loss. Furthermore, we also want to discuss the application value of laparoscopic lymph node dissection for spleen preservation in radical gastrectomy for proximal gastric cancer.
In this study patients will be offered intraperitoneal atomized chemotherapy as a supplement to the standard treatment of high-risk gastric cancer (laparoscopic removal of the stomach). Two commercially available oncologic drugs will be used (doxorubicin and cisplatin).
This study will investigate the safety and tolerability of ADP-A2M4CD8 T-cell therapy in subjects who have the appropriate human leukocyte antigen (HLA) and MAGE-A4 tumor antigen. Tumor indications include endometrial, esophageal, esophagogastric junction (EGJ), gastric, head and neck, melanoma, non-small cell lung (NSCLC), ovarian or urothelial cancer.
Title: A single-center, retrospective randomized controlled trial of artificial intelligence (AI) versus expert endoscopists for diagnosis of gastric cancer in patients who underwent upper gastrointestinal endoscopy. Précis: this single-center, retrospective randomized controlled trial will include 500 outpatients who underwent upper gastrointestinal endoscopy for gastric cancer screening and will compare the diagnostic detection rate for gastric cancer of AI and expert endoscopists. Objectives Primary Objective: to evaluate the diagnostic detection rate for gastric cancer of AI and expert endoscopists. Secondary Objectives: to determine whether AI is not inferior to expert endoscopists in terms of the number of images analyzed for diagnosis of gastric cancer and intersection over union (IOU), and the detection rate of diagnosis of early and advanced gastric cancer. Endpoints Primary Endpoint: diagnosis of gastric cancer. Secondary Endpoints: image based diagnosis of gastric cancer and IOU. Population: in total, 500 males and females aged ≥ 20 years who underwent upper gastrointestinal endoscopy for screening of gastric cancer at a single hospital in Japan. Describe the Intervention: AI-based diagnosis of gastric cancer based on upper gastrointestinal endoscopy images. Study Duration: 3 months.
