This phase I trial studies the best dose and side effects of mesenchymal stromal cells-derived exosomes with KrasG12D siRNA (iExosomes) in treating participants with pancreatic cancer with KrasG12D mutation that has spread to other places in the body. iExosomes may work better at treating pancreatic cancer.

Pancreatic carcinoma typically has a high recurrence rate and very poor prognosis. Surgery is the best choice for the treatment of pancreatic cancer, but for those advanced pancreatic cancer patients，when surgery is not available，chemotherapy combined with radiation therapy or interventional therapy is commonly used in the treatment，but the prolonging survival effect is not obvious. And now, some clinical researchers use CAR-T cells in the treatment of pancreatic carcinoma, according to the existing results, therapeutic effects are not as good as expecting. One of the most likely reasons is that they continued to use the intravenous infusing of CART cells to patients, when the T cells into the blood circulation, will result in decreased tumor activity and more potential adverse effects. We believe that a suitable TAA targeted-CAR-T cells will be an effective way to treat cancer, as long as the pathway of the cell infused to the body can not only improve the drug concentration of the tumor site but reduce the potential off-target side effects. In order to achieve this goal, it is probably the best choice to use vascular intervention to mediate CAR-T cells infusion. Mesothelin is a cell-surface antigen implicated in tumor invasion, which is highly expressed in pancreatic carcinoma but low-level expressed in mesothelia. We design a 2nd CART cells targeted with mesothelin, and use vascular intervention mediated CAR-T infusion to patients. We hope deliver anti-mesothelin CART cells locally can reducing the side effects while enhancing the antitumor affect by more CART cells accumulate in tumor sites while less can reach normal mesothelial tissue.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known if gemcitabine is more effective when given alone or in combination with another chemotherapy drug in treating cancer of the pancreas.

PURPOSE: Randomized phase II trial to compare the effectiveness of gemcitabine given alone or in combination with other chemotherapy drugs in treating patients who have metastatic cancer of the pancreas.

This study evaluates ADCT-301 in patients with Selected Advanced Solid Tumors. Patients will participate in a Treatment Period with 3-week cycles and a Follow-up Period every 12 weeks for up to 1 year after treatment discontinuation.

The purpose of this study is to evaluate the clinical activity of gemcitabine, nab-paclitaxel, capecitabine, cisplatin, and irinotecan (GAX-CI) in patients with metastatic pancreatic cancer.

Pancreatic cancer is a kind of digestive system tumor with high malignant degree and poor prognosis. Most patients with pancreatic cancer are locally advanced or have distant metastases at the time of diagnosis, so it is extremely important to find effective drugs to control tumor metastasis. The primary treatment regimen for advanced pancreatic cancer remains chemotherapy, which results in a median survival time of only 8 to 12 months. Therefore, there is an urgent need to explore new combination therapies to extend survival. Therefore, this study aims to evaluate the efficacy and safety of Adebrelimab and Chidamide in Combination with Gemcitabine and S1 as first-line treatment for locally advanced or metastatic pancreatic cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving the drugs in different combinations may kill more tumor cells. Chemoprotective drugs such as triacetyluridine may protect normal cells from the side effects of chemotherapy. It is not yet known which chemotherapy regimen is more effective in treating pancreatic cancer.

PURPOSE: Randomized phase III trial to compare the effectiveness of fluorouracil plus triacetyluridine with that of gemcitabine in treating patients who have locally advanced or metastatic pancreatic cancer that cannot be treated with surgery.

Hypoglycemia is the term used to refer to lower than normal levels of blood sugar. This study will continue to research the causes of hypoglycemia.

Patients involved in the study will be admitted to the Clinical Center of the National Institutes of Health and undergo tests for evaluating blood sugar. Patients will be required to refrain from eating for a set period of time and will undergo blood tests for insulin levels and several other specific diagnostic tests related to insulin secretion. The patients will be under supervision and will be provided with appropriate medical and surgical attention as needed.

RATIONALE: Drugs used in chemotherapy, such as capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.

PURPOSE: This phase II trial is studying how well capecitabine works as second-line therapy in treating patients with stage IV pancreatic cancer who have the thymidylate synthase gene.

Studies have shown that injecting local anesthetics in areas rich in blood vessels increases the risk of drug injection into blood vessels by mistake and increases the systemic absorption of drugs, which may increase the incidence of central nervous system and cardiovascular system toxic events caused by local anesthetics.EUS-CPN-related complications have not been clearly associated with local anesthetic adverse events.However, EUS-CPN local anesthetic injection area is located around the beginning of the abdominal trunk with abundant large and small blood vessels. The choice of local anesthetics with higher safety than bupivacaine, such as ropivacaine, is of great significance to ensure the safety of eus-cpn, especially for eus-cpn beginners.At present, there are no reports on the application of ropivacaine in eus-cpn.
