Active clinical trials for "Stomach Neoplasms"

Gastric cancer with retroperitoneal lymph node metastasis was considered as unresectable, to improve these patients' prognosis, we designed systematic conversion therapy including immunotherapy and chemoradiotherapy. The purpose of this study is to estimate safety and efficacy of Sintilimab in combination with chemoradiothrapy followed by D2 surgical resection in patients with advanced gastric cancer with retroperitoneal lymph node metastasis.

This multi-center, randomized controlled trial is designed to evaluate clinical effectiveness and cost-effectiveness of ESD for undifferentiated type of EGC meeting the expanded indication compared with surgery.

The primary objective in Phase I is to evaluate the safety and tolerability of ESG401 as a single agent administered in 21-day treatment cycles in previously treated participants with advanced epithelial cancer. In Phase II, the primary objective is to evaluate the safety and efficacy of ESG401 administered in 21-day treatment cycles at a dose selected in Phase I. Tumor types in the study will include: cervical, colorectal, endometrial, ovarian, esophageal, gastric adenocarcinoma, glioblastoma multiforme, head and neck cancers- squamous cell, hepatocellular, prostate, non-small-cell lung cancer, pancreatic, renal cell, small-cell lung cancer, non-triple negative breast cancer (non-TNBC), triple-negative breast cancer (TNBC) and metastatic urothelial cancer (mUC).

This trial will test the efficacy and safety of durvalumab in combination with vactosertib in patients with metastatic gastric cancers who failed ≥ 2 lines of chemotherapy

The aim of the study is to clarify whether octreotide therapy can reduce undesired postoperative weight loss, increase health-related quality of life and improve the appetite after surgery for esophageal or gastric cancer.

Gastric cancer is one of the most common malignant tumors of the digestive tract. Gastric cancer patients diagnosed for the first time in China have a higher proportion of advanced stages and a higher postoperative metastasis rate. Studies have shown that patients with good pathological response after preoperative neoadjuvant therapy (such as tumor regression grade, TRG0 or 1) have a better prognosis. The AIO-FLOT4 study found that preoperative perioperative FLOT chemotherapy not only prolonged the progression-free survival (PFS) time and overall survival (OS) time of patients with advanced gastric cancer, but also increased postoperative pathological remission rate. How to further improve the efficacy of the perioperative treatment plan may be beneficial to improve the long-term survival of gastric cancer patients. Several clinical studies have also confirmed that PD-1 antibody significantly prolongs the life of gastric cancer patients who have failed advanced chemotherapy in the back-line treatment. Thus the investigators plan to conduct this clinical trials to evaluate the safety and efficacy of Toripalimab (PD-1 antibody) combined with FLOT regimen in the perioperative period.The secondary end points included pathological remission rate, resection rate, D2 radical resection rate, 5-year disease-free survival (DFS) rate and 5-year OS rate.

This parallel, randomized, open-label study will evaluate the effect on overall survival of irinotecan on oxaliplatin and 5-fluorouracil (5-FU) in patients with HER2-negative and pMMR metastatic gastric cancer. Irinotecan will be administered as intravenous infusion of 150 mg/m2 every 2 weeks. Oxaliplatin will be given 85 mg/m2 and 5-FU will be given 400mg/m2 iv and 2400mg/m2 civ 48 hours fortnightly. Treatment will continue until disease progress or untolerable toxicity appears. The target sample size is 350-400 patients.

Alpelisib (BYL719) is a PIK3CA-specific inhibitor, which was developed by Novartis (Basel, Switzerland). Our group conducted pre-clinical study of alpelisib in eight gastric cancer cell lines: four PIK3CA wild-type (SNU638, SNU668, SNU1, and SNU16) and four PIK3CA mutant (SNU719, AGS, SNU601, and MKN). As a result, alpelisib preferentially inhibited the growth of gastric cancer cells with PIK3CA mutations. In addition, alpelisib inhibited cell growth via G1 arrest and subsequently induces apoptosis in GC cells, and this effect is more remarkable in cells harboring PIK3CA mutations. Moreover, alpelisib in combination with paclitaxel showed synergistic cytotoxic effects and significantly increased apoptosis compared with alpelisib or paclitaxel monotherapy in GC cells. The purpose of the study is to define the maximal tolerated dose (MTD) and recommended phase II dose (RP2D) of paclitaxel and alpelisib combination therapy in patients with advanced tumors and to evaluate the efficacy of paclitaxel and AZD8186 combination therapy as a second-line therapy in patients with advanced gastric cancer with PTEN aberrations. This study is divided into Phase IB and Phase II.

The purpose of this study is to learn about the feasibility and safety of using Peptide Receptor Radionuclide Therapy (PRRT) before and after surgical removal of a tumor. PRRT treatment is based on the administration of a radioactive product, 177-Lu DOTA-0-Tyr3-Octreotate (Lutathera®) and its use before and after surgery is thought to increase the overall survival benefit for patients with SSTR-positive gastroenteropancreatic neuroendocrine tumors GEP-NETs.

This is a phase II clinical trial assessing the safety and efficacy of sequential systemic and intraperitoneal (IP) chemotherapy in patients with primary gastric/gastroesophageal junction cancer with cytology positive peritoneal lavage and/or peritoneal carcinomatosis.
