In Phase 1b study, six subjects will be enrolled in Arm A (YL-13027 + AG regimen) and Arm B (HY-0102 + AG regimen). The first 12 subjects will be evaluated for safety after one cycle. After safety assessment, subjects will start to enroll in Arm C (YL-13027 + HY-0102 + AG regimen). Each group is planned to include 12-20 subjects. According to the safety and efficacy results of 3 arms of subjects in phase Ib, 1-2 groups were selected for expansion, and a randomized controlled study will be conducted with the standard treatment AG （Arm 4）regimen chemotherapy.
Pancreatic adenocarcinoma (PAAD) patients following surgeries are prone to relapse shortly, while it is not well understood by current biomarkers. Given the potential associations of human leukocyte antigen class I (HLA-I) genotype with oncogenic mutational profile and immunotherapy efficacy, we aimed to assess whether differential HLA-I genotype could predict the postoperative outcomes in resected PAAD patients.
Research Hypothesis: The combination of ionizing radiation and immunotherapy (durvalumab) is well tolerated and stimulates a clinically significant pancreas-cancer specific immune response.
The primary objective will be to evaluate whether the combination of RT and durvalumab can improve median PFS compared to chemotherapy historical control data in metastatic pancreas cancer patients who have progressed through first-line chemotherapy.
The primary intent of RT in this study is to augment a pancreatic cancer-specific immune response when given with durvalumab.
The aim of this observational multicenter retrospective cohort study is to evaluate the differences in risk factors, prognosis, clinicopathological and metabolic characteristics between early-onset pancreatic neuroendocrine tumors (EO-PanNETs) and late-onset pancreatic neuroendocrine tumors (LO-PanNETs).
The main questions it aims to answer are:
Are there distinct clinical, pathological, and metabolic profiles in EO-PanNETs compared with LO-PanNETs? Do EO-PanNETs have different prognostic outcomes compared with LO-PanNETs? Researchers will compare EO-PanNET patients with LO-PanNET patients and with matched nonmalignant controls to assess differences in tumor characteristics and associated metabolic conditions.
Participants will:
Provide retrospective clinical, pathological, and metabolic data from hospital records.
Have survival and recurrence outcomes assessed through follow-up data review.
Pancreatic cysts are found incidentally on 15-50% of CT and MRIs for all indications and their prevalence is increasing. Many of these cysts may be precursors to pancreatic cancer, and thus pose a substantial risk, however, the vast majority are benign. Increased detection of pancreatic cysts provides an opportunity to diagnose pancreatic malignancy at an early, curable stage yet also increases the potential to over-treat clinically insignificant lesions. This presents a clinical challenge to prevent unnecessary resection of indolent disease, with associated risks of infections, bleeding, diabetes, and costly disability. Unfortunately, there is little information on the epidemiology and natural history of pancreatic cysts to help guide management.
Radiofrequency ablation has been used for treatment of solid neoplasms of the liver, lung, kidney and adrenal. Recently, EUS-guided RFA has become available and the device allows EUS-guided treatment of pancreatic neoplasms. The procedure has been shown to be feasible in the porcine pancreas and was used to treat small groups of patients that are not suitable for surgery suffering from pancreatic neoplasms.
The aim of the current study is to perform a multi-center prospective study on EUS-guided radiofrequency ablation (RFA) of solid pancreatic neoplasms. The hypothesis is that EUS-guided RFA is safe, feasible and effective for treating solid pancreatic neoplasms.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug or giving drugs in different ways may kill more tumor cells.
PURPOSE: Randomized phase II trial to compare the effectiveness of gemcitabine with or without CI-994 in treating patients who have advanced pancreatic cancer.
The purpose of this study is to determine whether S-1 is effective in slowing tumor activity in participants with locally advanced or metastatic pancreatic cancer who have not had chemotherapy. The study is also looking at the safety of S-1.
The purpose of this study is to determine the safety and efficacy of an investigational study drug DN-101 (calcitriol) when given in combination with gemcitabine ± erlotinib in the treatment of pancreatic cancer.
This is a study in which pancreatic cancer patients receive a combination therapy with CART-meso cells and CART19 cells administered at 3 days after one dose of cyclophosphamide. CART-meso cells are patients' own T cells that were modified in the laboratory to express a receptor specific to the mesothelin protein. CART19 cells are patients' own T cells that were modified in the laboratory to express a receptor specific to a protein called CD19. The CD19 protein is expressed on white blood B cells. CART19 cells are expected to attack the B cells and impede the antibody response against CART-meso cells. The investigators hypothesize that this combination therapy may prolong the duration of CART-meso cells in the body. Additionally, one dose of cyclophosphamide may enhance engraftment and persistence of CART cells.
