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.

The main objective of the Phase 2 part of the study is to evaluate the efficacy of bemarituzumab (FPA144), a targeted antibody, in combination with modified FOLFOX6 compared to placebo in combination with modified FOLFOX6 in participants with advanced gastrointestinal cancer.

This study will be conducted in two stages: 1) safety validation and 2) dose expansion Safety Validation Cohort: The first portion of the study will preliminarily establish the tolerability of the combination of pembrolizumab, oxaliplatin and capecitabine. Five (5) subjects will be enrolled and their safety data after 21 days of treatment will be reviewed before additional subjects are enrolled. Subjects on this portion of the study will only be enrolled at the Duke Cancer Institute. Dose Expansion Cohort: The second portion of the study (ie. phase II) will enroll 30 subjects. In the dose expansion cohort, the first cycle will be modified to allow one week of pembrolizumab monotherapy before starting capecitabine and oxaliplatin (XELOX) chemotherapy, which will allow analysis of biomarkers related to pembrolizumab. Subjects on this portion of the study will be enrolled at the Duke Cancer institute and select external collaborating institutions. The primary objective of this trial is to describe the progression free survival (PFS) associated with the combination of pembrolizumab, oxaliplatin and capecitabine (pembrolizumab +XELOX) in all patients with previously untreated metastatic esophagogastric adenocarcinoma.

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 aim of this study was to compare the efficacy and safety of POF, FOLFOX, and FOLFOX plus paclitaxel(ip) as first-line treatment in AGC a phase II clinical trial.

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.

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.

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.

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.
