Active clinical trials for "Stomach Neoplasms"

A Phase 2, Multicenter, Open-Label Study of DKN-01 in Combination with Tislelizumab ± Chemotherapy as First-Line or Second-Line Therapy in Adult Patients with Inoperable, Locally Advanced or Metastatic Gastric or Gastroesophageal Junction Adenocarcinoma

Reduced port laparoscopic gastrectomy has been adopted in clinical. The safety and outcome of reduced port laparoscopic gastrectomy has not been systematically evaluated. The investigators sought to compare the short and long-term outcome of patients with gastric cancer who underwent reduced port gastrectomy with patients underwent traditional laparoscopic gastrectomy

This is a single arm study to evaluate the efficacy and safety of CEA-targeted CAR-T cells therapy for patients with relapsed/refractory CEA+ Cancer,and obtain the recommended dose and infusion plan.

Stomach cancer is recognized as the third leading cause of death of cancer patients worldwide. Despite the radical treatment carried out, the progression of gastric cancer occurs in 30-40% of patients. The most common type of tumor progression of this localization is peritoneal carcinomatosis. When peritoneal carcinomatosis occurs, the median survival of patients does not exceed 3 months, the overall survival is no more than 6 months. Unfortunately, when peritoneal carcinomatosis occurs, palliative chemotherapy remains the only treatment option. The modern strategy for the prevention and treatment of peritoneal carcinomatosis is based on the concept of regional chemotherapy. The main methods of regional chemotherapy are hyperthermic intraperitoneal chemotherapy (HIPEC) and Pressured Intraperitoneal Aerosol Chemotherapy (PIPAC). PIPAC is a new technology for delivering chemotherapy drugs to tumor nodes on the surface of the peritoneum and allows the cytostatic to be evenly distributed over the abdominal cavity, increasing the depth of its penetration into tumor nodes due to the properties of aerosol and gradients of intra-abdominal and interstitial pressure. The method has a number of advantages over the HIPEC method: a large penetration depth of drugs, low trauma, the possibility of repeated use. We offer PIPAC for patients with locally advanced gastric cancer and a high risk of developing peritoneal carcinomatosis in an adjuvant mode in addition to standard treatment to prevent the development of carcinomatosis.

This phase I trial identifies the best dose, possible benefits and/or side effects of BAY 1895344 in combination with chemotherapy in treating patients with solid tumors or urothelial cancer that has spread to other places in the body (advanced). BAY 1895344 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Cisplatin and gemcitabine are chemotherapy drugs that stop the growth of tumor cells by killing the cells. Combining BAY 1895344 with chemotherapy treatment (cisplatin, or cisplatin and gemcitabine) may be effective for the treatment of advanced solid tumors, including urothelial cancer.

The aim of this study is intending to provide the optimal procedures of the peristaltic direction of gastrointestinal anastomosis in Roux-en-Y reconstruction after distal curative gastrectomy for gastric cancer, which can provide the best operation mode of Roux-en-Y anastomosis in digestive tract reconstruction during distal gastrectomy for reducing postoperative complications and improving quality of life for patients.

In this study, we combine Nab-PTX, S-1 and sintilimab as adjuvant regimen to patients with stage IIIC GC. We are aiming to investigate the recommended dose of this regimen in a phase I study and estimate the toxicity and efficacy of this regimen in a phase II study.

Neoadjuvant therapy for locally advanced gastric cancer is still in the exploratory stage. With the emergence of immune checkpoint inhibitors, neoadjuvant chemoimmunotherapy is also in the exploratory stage in locally advanced gastric cancer. At present, chemotherapy combined with immunotherapy is usually a simple combination of chemotherapeutic drugs and immune drugs, without taking into account of the influenece of applied sequence. The purpose of this study is to explore whether the sequence of chemotherapy and immunotherapy influence the complete pathological response rate in locally advanced gastric cancer.

Background: Approximately 15% of gastric adenocarcinoma patients presents with peritoneal carcinomatosis (PC) at the first encounter and is regarded as an unresectable and end-stage disease. The recommended treatment with palliative chemotherapy alone yields a poor clinical efficacy. Emerging evidences suggest the survival benefits of complete cytoreductive surgery (CRS) combined with normothermic intraperitoneal chemotherapy (N-IPEC) for gastric adenocarcinoma with limited PC. Objective: To evaluate the 6-month disease control rate (DCR) of complete CRS combined with N-IPEC and systemic chemotherapy for gastric adenocarcinoma with limited PC. Patients and methods: Patients having gastric adenocarcinoma with PCI ≤ 10 (Arm-A) or positive peritoneal wash cytology (CY1/P0) (Arm-B) will be enrolled. Patients with other distant metastasis, including brain, lung, liver, bone, will be excluded. All patients should undergo ≥ D2 gastrectomy and complete CRS followed by N-IPEC (paclitaxel] and systemic chemotherapy (high-dose fluorouracil and cisplatin [P-HDFL], or capecitabine and oxaliplatin [CAPOX]). N-IPEC (paclitaxel) will be administered in combination with systemic P-HDFL or CAPOX on day 1,8,15 or day 1,8 for each cycle, respectively. The disease status will be evaluated every 12 weeks based on the computed tomography scan, and the clinical evaluation (outpatient follow-up) will be performed every 2 weeks for whom receiving P-HDFL and every 3 weeks for whom receiving CAPOX. Patients will receive maximal 6 cycles N-IPEC with P-HDFL or 8 cycles N-IPEC with CAPOX. After N-IPEC is discontinued, P-HDFL or CAPOX will be continued alone until disease progression or death. The primary endpoint of this study is 6-month DCR, and the secondary endpoints include 6-month response rate for ascites, 1-year progression-free survival (PFS) and overall survival (OS), 3-year PFS and OS, and safety profiles. Based on Simon's minimax two-stage design, this trial will be carried out in two stages. In stage I, a total number of 13 (Arm-A) / 16 (Arm-B) patients is accrued. If there are ≤ 6 (Arm-A) / ≤ 14 (Arm-B) progression-free among these 13 (Arm-A) / 16 (Arm-B) patients, the study will be early stopped. Otherwise, additional 17 (Arm-A) / 2 (Arm-B) patients will be accrued in stage II, resulting in a total number sample size of 30 (Arm-A) / 18 (Arm-B). Expected result: A ≥ 75% (Arm-A) / ≥ 95% (Arm-B) 6-month DCR could be achieved for gastric adenocarcinoma patients with limited PC (Arm-A) / with CY1P0 (Arm-B) via this treatment strategy (complete CRS + N-IPEC + P-HDFL or CAPOX) -i.e., if there are ≥ 21 (Arm-A) / ≥ 16 (Arm-B) progression-free among the 30 (Arm-A) / 18 (Arm-B) enrolled patients, we will reject the null hypothesis and claim that the treatment is promising.

A total of 297 subjects are estimated to enroll in the study, with 15 eligible subjects enrolled in the 1st stage at most and 282 evaluable subjects in the 2nd stage. All subjects are adult patients with age over 18-year-old; they must be diagnosed with recurrent or metastatic gastric cancer with peritoneal metastasis at the time of enrollment; and failed at least prior two standard systemic anti-cancer therapies for recurrent or metastatic gastric cancer, before enrollment. In the first stage, pharmacokinetic characteristics and preliminary safety of catumaxomab will be explored in Asian patients with gastric cancer ; in Cohort A, the enrolled subjects will receive the first infusion at 10μg on day 1, which will be increased to 20 μg, 50 μg and 150 μg on days 4, 8 and 11, respectively. 42 days are defined as a cycle. From the second cycle, catumaxomab will be changed to 20 μg, 50 μg, 150 μg on days 1, 4, 8 respectively. In Cohort B, 28 days are defined as a cycle. It is estimated to enroll 6 subjects in each cohort first. In the second stage, approximate 282 subjects who meet the enrollment criteria are randomized into either catumaxomab infusion group (catumaxomab group) or treatment of investigator choice group (IC group), at a ratio of 2:1. Subjects at the first and second stages will continue the treatment until one of the following conditions occurs:1)Significant progression of tumor lesions, including but not limited to peritoneal metastases lesions and/or ascites; 2)Intolerable toxicity; 3)The investigator believes that patients need to withdraw from the study and receive other treatment;4)death;5)Withdrawal of informed consent.
