Active clinical trials for "Stomach Neoplasms"

Efficacy and Safety of Disitamab Vedotin Combined With Sintilimab in Second-line Treatment of Advanced Gastric Cancer: a Prospective, Single Arm Clinical Study

Endoscopic submucosal dissection (ESD) is the technique that has replaced surgery in the treatment of early neoplastic lesions of the stomach (LNPS). ESD of LNPS allows: a) less invasiveness compared to surgery; b) greater chances of "en bloc" resection and R0 resection compared to mucosectomy for lesions larger than 15 mm. Recent 2015 ESGE guidelines provide precise recommendations for the use of ESD in the treatment of LNPS, but Italy lacks prospective data on the efficacy and safety of ESD in a large sample of patients. A multicenter prospective observational study to create a database on the use of ESD in LNPS is essential to provide information regarding the efficacy and safety of ESD in Italy. This database would also provide information regarding the criteria applied in the use of ESD in the treatment of early gastric neoplasia

This is a Phase 1b/2 study to identify the recommended dose of M7824 for further study with weekly paclitaxel, and to assess the safety and clinical efficacy of this combined treatment in advanced gastric cancer after first line treatment. The study will be conducted in two parts: Part 1 (Phase 1b) dose escalation study to determine the MTD and RP2D of weekly paclitaxel in combination with fixed dose M7824, Part 2 (Phase 2) to further evaluate the safety and tolerability of the combination of M7824 and paclitaxel at the RP2D and determine anti-tumor activity.

The researching subject is aimed to obtain the clinical evidences (including real benefits， risks ,etc. ) of traditional Chinese medicine in the treatment of advanced gastric cancer by compared with the outcomes that not accept the traditional Chinese medicine. the subject acquires these clinical practices by using the methods of multicenter、persisting registry (the real world researching technology ) and propensity score.

There is no evidence available about which molecular profiling methods are currently used for cancer patients in Austrian clinical practice. The construction of the registry proposed as a completely independent research endeavor, will be helpful for scientific evaluation and the establishment of highly credible data.

The project will aim to identify and determine subgroups of patients with different risks of progression to gastric cancer and to assess appropriate follow-up intervals. Implementing risk stratification only high risk individuals will be offered and performed endoscopic surveillance.

This study is a single center, phase II study, to evaluate the effectiveness and safety of POF(paclitaxel plus oxaliplatin plus 5-fluorouracil plus leucovorin) , in the neoadjuvant therapy for patients with advanced/metastatic gastric cancer.

This phase I trial studies a new imaging technique called FAPi PET/CT to determine where and to which degree the FAPI tracer (68Ga-FAPi-46) accumulate in normal and cancer tissues in patients with non-prostate cancer. The research team also want to know whether what they see on PET/CT images represents the tumor tissue being excised from the patient's body. The research team is also interested to investigate another new imaging technique called PSMA PET/CT. Participants will be invited to undergo another PET/CT scan, with the PSMA tracer (68Ga-PSMA-11). This is not required but just an option for volunteer patients. Patients who have not received an 18F-FDG PET/CT within one month of enrollment will also undergo an FDG PET/CT scan. The PET/CT scanner combines the PET and the CT scanners into a single device. This device combines the anatomic (body structure) information provided by the CT scan with the metabolic information obtained from the PET scan. PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of, in the case of this research, 68Ga-PSMA-11 and 68Ga-FAPi, and 18F-FDG (if applicable). Because some cancers take up 68Ga-PSMA-11 and/or 68Ga-FAPi it can be seen with PET. CT utilizes x-rays that traverse the body from the outside. CT images provide an exact outline of organs where it occurs in patient's body. FAP stands for Fibroblast Activation Protein. FAP is produced by cells that surround tumors. The function of FAP is not well understood but imaging studies have shown that FAP can be detected with FAPI PET/CT. Imaging FAP with FAPI PET/CT may in the future provide additional information about various cancers. PSMA stands for Prostate Specific Membrane Antigen. This name is incorrect as PSMA is also found in many other cancers. The function of PSMA is not well understood but imaging studies have shown that PSMA can be detected with PET in many non-prostate cancers. Imaging FAP with PET/CT may in the future provide additional information about various cancers.

This is a randomized, multicenter, controlled study to compared the Efficacy and Safety of XELOX combined with Apatinib versus XELOX as post-operative chemotherapy in locally advanced gastric signet ring carcinoma with D2 dissection.

The trial is a prospective, randomized, controlled phase Ⅱ study which will be conducted in Chinese PLA General Hospital, Beijing, China. Patients with eligibility will enrolled and assigned into either group A for 9 weeks of nivolumab, S-1 combined with oxaliplatin (Nivo+SOX) followed by D2 surgery and group B for 9 weeks of nivolumab followed by D2 surgery. The primary endpoint is the safety assessed by recording adverse events and the secondary endpoints are response rate, disease control rate, pathological complete response rate, D2 rate and R0 rate.
