Active clinical trials for "Stomach Neoplasms"

The metabolic effect of oncometabolic surgery (long limb Roux-en Y reconstruction) for early gastric cancer patients has been revealed in a few pilot studies. However, the nutritional safety has not been dealt with in previous literatures. This is a prospective pilot study for evaluating the nutritional safety and metabolic benefits of oncometabolic surgery for obese early gastric cancer patients.

This phase Ib/II trial studies the side effects of IRX-2, cyclophosphamide, and pembrolizumab work in treating participants with gastric or gastroesophageal junction cancer that has come back or that has spread to other places in the body. Interleukins, such as those found in IRX-2, are proteins made by white blood cells and other cells in the body and may help regulate immune response. Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving RX-2, cyclophosphamide, and pembrolizumab may work better in treating participants with gastric or gastroesophageal junction cancer.

This is a Phase 2, multi-cohort study to investigate safety, PK, and preliminary anti-tumor activity of the monoclonal antibody BGB A317 in combination with standard chemotherapy as first-line treatment. Cohorts include an ESCC cohort and a gastric carcinoma (GC) or GEJ carcinoma cohort that will be enrolled concurrently. The study includes a screening (up to 28 days), treatment (until disease progression, intolerable toxicity, or treatment withdrawal for another reason), safety follow-up (up to 30 days following last study drug treatment), and survival follow-up phase.

The purpose of this study is to evaluate the efficacy and tolerability of the maintenance treatment of tegafur-uracil (UFT) after the standard first-line chemotherapy in advanced gastric cancer.

The purpose of this study is to investigate the activity of amivantamab in gastric cancer (GC) and esophageal cancer (EC) participants (Phase 2a), and to characterize the preliminary antitumor activity of amivantamab in selected GC and EC population (Phase 2b).

In order to improve postoperative ileus in patients undergoing gastrointestinal surgery, digestive medications and prokinetics have been routinely used. Among them, mosapride citrate is widely used as a representative drug, as it is a 5-hydroxytryptamine 4 receptor agonist that increases gastrointestinal motility. Prucalopride succinate (dihydrobenzofurancarboxamide) is a type of 5-hydroxytryptamine 4 receptor agonist that has a higher affinity for the 5-HT4 receptor compared to mosapride (a benzamide derivative) which belongs to the same class of drugs. Prucalopride succinate has been demonstrated to increase both gastric and colonic motility through in vivo and in vitro studies. As mentioned earlier, it exhibits high specificity for the 5-HT4 receptor. The 5-HT4 receptor is not expressed in the gastric mucosa but is expressed at low concentrations in the small intestine, whereas it is highly expressed in the colonic mucosa. Therefore, prucalopride is widely used as a therapeutic agent for chronic constipation by increasing colonic motility. Furthermore, Prucalopride succinate stimulates the 5-HT4 receptors present in the nerve terminals of the myenteric plexus, promoting the release of acetylcholine. The released acetylcholine acts on α7nAch receptors located on the surface of enteric smooth muscle cells, inhibiting inflammatory responses and reducing postoperative ilues. A randomized controlled trial (RCT) conducted on 110 patients who underwent gastrointestinal surgery demonstrated that prucalopride succinate showed significant improvement in gastrointestinal motility compared to the control group. Currently, mosapride citrate is widely used as a prokinetic agent in clinical practice. However, preliminary studies have shown no significant efficacy, and when comparing abdominal X-ray images taken on the third day after surgery, there is no significant difference compared to the placebo group. As a result, it can be observed that the recovery of gastrointestinal motility after surgery is not primarily due to small bowel motility but rather delayed gas passing caused by colon motility. Therefore, it can be assumed that using drugs that increase colon motility may be effective in improving gastrointestinal motility after surgery.

This is a Phase Ib/II study to identify the recommended dose of paclitaxel and nivolumab for further study, and to assess the safety and clinical efficacy of this combined treatment in EBV-related, MSI-high, or PD-L1 positive advanced gastric cancer after first line treatment.

This study is to develop methods for identification of neoantigens from patients with gastric cancer.

The beneficial of perioperative usage of thoracic epidural anesthesia and analgesia in various thoracic and upper abdominal surgery are well studied. However, intraoperative data are lacking whether combined thoracic epidural and general anesthesia have effect on the median (50%) effective effect-concentration (EC50) of propofol for inducing loss of consciousness (LOC). We performed this study among patients undergoing open gastrectomy in gastric cancer patients. Sixty patients undergoing open gastrectomy were randomly assigned to two groups with thoracic combined general anesthesia (TEA+GA) or general anesthesia (GA) alone. Target-controlled infusion (TCI) of propofol was used for anesthesia induction. The initial propofol concentration of target effect-site (Ceprop) was 3.5 ug/ml and was increased stepwise by 0.5ug/ml at each 4 min intervals by an un-down sequential method to reach LOC. The predicted Ceprop at the time of LOC, intravenous anesthetics, vasopressor requirement, emergency time from anesthesia and postoperative numeric rating scale (NRS) were recorded and analyzed between two groups.

A single-center, observational study, integrated biomarker analysis of HIPEC combined Programmed cell death 1 /Programmed cell death 1 ligand 1(PD1/PDL1)inhibitor in previously treated patients of advanced gastric cancer with peritoneal metastasis. Tests will be performed on tumor tissue and blood samples, and imaging assessments will be reviewed in order to monitor how well each patient responds to treatment. This is an observational study, so participants will not receive cancer treatment, other than the treatment received as standard of care.
