Trial Comparing 19 and 25G Needles for Fine Needle Aspiration (FNA) of Solid Pancreatic Mass Lesions Greater Than 35mm

This study will test two different needles for performing a biopsy of the pancreas during endoscopic ultrasound (EUS) procedures. Patients who are asked to participate in this study have a growth in the pancreas measuring greater than 35mm that needs a biopsy so that a diagnosis can be made. The biopsy can be performed using either a 19 or 25-Gauge needle. The purpose of this study is to compare which of the two needles is better for performing biopsies of the pancreas on masses that are greater than 35mm.

Dasatinib and Gemcitabine Hydrochloride or Gemcitabine Hydrochloride Alone in Treating Patients With Pancreatic Cancer Previously Treated With Surgery

RATIONALE: Dasatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as gemcitabine hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving dasatinib together with gemcitabine hydrochloride is more effective than gemcitabine hydrochloride alone in treating pancreatic cancer. PURPOSE: This randomized phase II trial is studying how well giving dasatinib together with gemcitabine hydrochloride works compared to giving gemcitabine hydrochloride alone in treating patients with pancreatic cancer previously treated with surgery.

Pembrolizumab In Combination With Debio 1143 In Pancreatic and Colorectal Advanced/Metastatic Adenocarcinoma

This trial is a Phase I study to be conducted in patients with non-MSI-high advanced/metastatic pancreatic ductal adenocarcinoma (PDAC) or colorectal cancer (CRC) and is divided in two Parts.

* Dose escalation Part :To determine the Maximum Tolerated Dose (MTD) and the Recommended Dose for Phase 2 (RP2D) of Debio1143 when combined with a fixed dose of Pembrolizumab.
* Extension Part: To evaluate preliminary efficacy data of the proposed combination.

ProAgio in Previously Treated Advanced Pancreatic Cancer and Other Solid Tumor Malignancies

The study is a first-in-human, Phase I study to assess the safety of ProAgio in participants with advanced solid tumor malignancies including pancreatic cancer.

Clinical Study of a Personalized Neoantigen Cancer Vaccine in Treating Patients With Advanced Pancreatic Cancer

This research study is evaluating a new type of pancreatic cancer vaccine called &#x0022Personalized Neoantigen Cancer Vaccine&#x0022 as a possible treatment for advanced pancreatic cancer. The purpose of the clinical study is evaluating the safety, tolerability and partial efficacy of the personalized neoantigen cancer vaccine in the treatment of Chinese patients with advanced pancreatic cancer, so as to provide a new personalized therapeutic strategy for advanced pancreatic cancer patients.

It is known that cancer patients have mutations (changes in genetic material) that are specific to an individual patient and tumor. These mutations can cause the tumor cells to produce proteins that appear very different from the body's own cells. It is possible that these proteins used in a vaccine may induce strong immune responses, which may help the participant's body fight any tumor cells that could cause the cancer to come back in the future. The study will examine the safety of the vaccine when given at several different time points and will examine the participant's blood cells for signs that the vaccine induced an immune response.

Erlotinib and Cetuximab With or Without Bevacizumab in Treating Patients With Metastatic or Unresectable Kidney, Colorectal, Head and Neck, Pancreatic, or Non-Small Cell Lung Cancer

This randomized phase I/II trial studies the side effects, best way to give, and best dose of erlotinib and bevacizumab when given with cetuximab and how well giving erlotinib and cetuximab together with or without bevacizumab works in treating patients with metastatic or unresectable kidney, colorectal, head and neck, pancreatic, or non-small cell lung cancer. Erlotinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as cetuximab and bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Cetuximab and bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving erlotinib together with cetuximab and/or bevacizumab may kill more tumor cells.

Gemcitabine and Celecoxib Combination Therapy in Treating Patients With R0 Resection Pancreatic Cancer

The prognosis of pancreatic cancer is extremely poor, even in those patients who had underwent surgery, the 5-year survival is still less than 10%. Current guidelines recommend Gemcitabine monotherapy for R0 resection of pancreatic cancer. Inflammation plays an critical role in the development and progression of pancreatic cancer. Here we intend to assess the synergistic effect of using celecoxib in combination with gemcitabine on the treatment of R0 resection of pancreatic cancer.

Analyzing Childhood Recall Antigens in Patients With Pancreatic Cancer

The investigator is developing an immune therapy against pancreatic cancer. Immune cells, known as &#x0022T cells with tumor killing capacity&#x0022, are involved in this immune therapy. In mice with pancreatic cance there is evidence that one tetanus toxoid (TT) vaccination (that patients receive from childhood) combined with Gemcitabine activates these killer T cells. (Gemcitabine improves T cell responses) These killer T cells are able to destroy tumor cells uploaded with TT protein (such studies are planned in future clinical trials). The goal of this study is to test whether one TT vaccination combined with Gemcitabine treatment activates the same T cells in pancreatic cancer patients.

Study With CY, Pembrolizumab, GVAX Pancreas Vaccine, and SBRT in Patients With Locally Advanced Pancreatic Cancer

This study will be looking at whether combining cyclophosphamide, pembrolizumab (an antibody that blocks negative signals to T cells), GVAX (pancreatic cancer vaccine), and SBRT (focused radiation) is effective (anti-tumor activity) and safe in patients with locally advanced pancreatic cancer.

Safety and Efficacy of EUS-RFA in the Treatment of Pancreatic Lesions: A Prospective Registry

Purpose: The purpose of this registry is to track the clinical outcomes and progression of patients with pancreatic lesions receiving endoscopic ultrasound (EUS)-based radiofrequency ablation (RFA) therapy.

Research Design: This study is a 7-year, single-center prospective registry study with annual follow up. Patients with pancreatic lesions undergoing EUS-guided RFA treatment will be studied. There will be no deviation from standard of care procedures.

Procedures to be Used: Following recruitment into the program, eligible patients will undergo EUS-RFA for the treatment of their pancreatic lesion and/or malignancy as part of their standard of care.

Endoscopic Intervention: The EUS-guided intervention will be performed based on a clinical decision. The data will be collected for research purposes. Briefly, the procedure involves advancing a 19-gauge EUS-RFA catheter into the target lesion under EUS-guidance. RFA energy is then applied in 2-10 cycles with each cycle lasting about 10 to 30 seconds and the power setting ranging from 10 to 30 Watts. The same physician who performs the initial EUS-RFA procedure will be responsible for subsequent EUS-RFA procedures.

Risks and Potential Benefits: This is a minimal-risk study with associated physical risks being those part of routine standard of care. Additional risks associated with this study include the possible loss of confidentiality if the patient data or information is inadvertently disclosed outside of this study, risks associated with obtaining blood samples, and risks associated with obtaining tissue samples via biopsy. However, all information will be kept strictly confidential and will be used only for research purposes by the listed investigators. Patients will not receive any additional benefit from the study aside from those received as part of standard of care.
