Active clinical trials for "Stomach Neoplasms"

The main purpose of this trial is to investigate the safety and tolerability of TAEST16001（TCR Affinity Enhancing Specific T cell Therapy）in the multi-line treatment failed advanced solid tumors except non small cell lung cancer,including liver cancer,gastric cancer,esophageal cancer,bone and soft tissue tumors,breast cancer, bladder carcinoma,prostate carcinoma,thyroid cancer, ovarian cancer and so on. The patients must meet the two criteria: human leukocyte antigens (HLA)-A*0201+ and NY-ESO-1 positive cells≥25% by immunohistochemistry.

Open-label, Phase I-II, first-in-human (FIH) study for A166 monotherapy in HER2-expressing or amplified patients who progressed on or did not respond to available standard therapies. Patients must have documented HER2 expression or amplification. The patient must have exhausted available standard therapies. Patients will receive study drug as a single IV infusion. Cycles will continue until disease progression or unacceptable toxicity.

Safety and efficacy study of neoadjuvant chemotherapy (FLOT versus SOX) for gastric cancer patients in high volume center of China

The INTEGA study assesses therapy Options for advanced or metastatic esophagogastric Adenocarcinoma in patients overexpressing human epidermal receptor type 2 (HER2 positive patients). Current treatment options in this situation include chemotherapy based palliative treatment in combination withTrastuzumab. Recent studies have shown that immunotherapy with Nivolumab or Ipilimumab after previous chemotherapy can also improve survival in esophagogastric cancer. This study assesses the efficacy of two experimental first line treatment strategies: A) Chemo-free immunotherapy with Trastuzumab, Nivolumab and Ipilimumab and B) addition of Nivolumab to the standard regimen (FOLFOX chemotherapy and Trastuzumab).

There is no accepted standard therapy for patients with advanced gastric cancer who have progressed during or after second-line therapy. The role of 3rd line treatment in advanced gastric cancer has not been proven. As a novel target of gastric cancer, SMO overexpression is chosen in this study, and the investigators plan this study to evaluate the efficacy and safety of vismodegib in gastric cancer. The doses of vismodegib are based on trials of basal cell carcinoma.

In this four-part study, NKTR-214 was administered in combination with nivolumab and with/without other anticancer therapies. Part 1 considered escalating doublet (NKTR 214 + nivolumab) doses to determine the RP2D. Part 2 considered dose expansion cohorts for the doublet (NKTR 214 + nivolumab ± chemotherapy). Part 3 was schedule-finding for a triplet therapy (NKTR 214 + nivolumab + ipilimumab). Part 4 dose expansion for the triplet (NKTR 214 + nivolumab + ipilimumab) was planned to further assess the efficacy of the RP2D triplet combination at dosing schedules from Part 3.

This study is for patients with non-resectable, recurrent, or metastatic well or moderately differentiated gastroenteropancreatic neuroendocrine tumors (GEP-NETs). The study will be conducted in two stages: 1) Safety Run-In and 2) Expanded Cohort. Safety run-in: The first stage will include a safety run-in of 6 patients treated with pembrolizumab 200 mg intravenous (IV) every 3 weeks and lanreotide depot 90mg subcutaneous (SQ) every 3 weeks. Up to 6 patients at the Duke Cancer Institute will be accrued at the starting dose level. If one or less subject meets treatment-related discontinuation criteria (as specified in the protocol) during Cycle 1, then the study will proceed to the second stage, Expanded Cohort. Expanded Cohort: Patients will be treated with pembrolizumab 200mg IV every 3 weeks and lanreotide depot 90mg SQ every 3 weeks as determined by the Safety Run-In Cohort.

Apatinib dose titration in Advanced or Metastatic Gastric Cancer

The aim of surgical procedures for resection of cancer stomach is to resection of the tumor mass with safety margin and its drainage lymph nodes (lymphadenectomy). There are two main types of techniques (open & laparoscopic) Many studies were done comparing these two techniques showed that Laparoscopic resection is superior in early postoperative recovery (less pain ,less bleeding and shorter hospital stay) but less radical than open resection (less safety margin & less lymphadenectomy) but because of the ongoing advances on laparoscopic surgery these results needs more and more revision. So the investigators conduct this randomized controlled trial aiming at comparing open and laparoscopic resection of cancer stomach to choose the best surgical procedure for resection of cancer stomach.

The effective rate of second-line and later-line single-agent therapy for advanced gastric cancer is limited. This research plan aims to explore whether the combination of drugs can further improve the benefits of second-line and above therapies. Previous studies have shown that there is a significant synergistic effect between chemotherapy and PD-1 monoclonal antibody, or anti-angiogenic TKI drugs and PD-1 monoclonal antibody. This project is planned to be based on the classic chemotherapy drugs irinotecan or paclitaxel, combined with mesylate Apatinib and PD-1 monoclonal antibody, explore the effectiveness and safety of this three-drug combination regimen for the second-line and above treatment of advanced gastric cancer, in order to provide a better late-line treatment plan for patients with advanced gastric cancer.
