Phase II Trial of Erlotinib in Advanced Pancreatic Cancer

This is an open-label, multi-center phase II study of erlotinib in patients with metastatic or locally advanced, unresectable pancreatic cancer who have received up to one line of gemcitabine based chemotherapy.

A Study of Mipasetamab Uzoptirine (ADCT-601) in Participants With Solid Tumors

The primary objective of this study is to identify the recommended phase 2 dose (RP2D) and/or the maximum tolerated dose (MTD), and characterize the safety and tolerability of ADCT-601 monotherapy and in combination with gemcitabine.

Chemoimmunotherapy and Radiation in Pancreatic Cancer

The goal of this study is to evaluate the safety of combination treatment that includes chemotherapy, radiation therapy, and immunotherapy in patients with pancreatic cancer.

Evaluating the Potential Usefulness of 18F-AlF-FAPI PET/CT in Patients With Gastrointestinal Tumors and Compared With 18F-FDG PET/CT

To evaluate the potential usefulness of 18F-AlF-FAPI positron emission tomography/computed tomography (PET/CT) for the diagnosis of primary and metastatic lesions in gastrointestinal tumors, and compared with 18F-FDG PET/CT.

The Role of ctDNA, PVT1 and ROS in Diagnosis and Treatment of Gastrointestinal and Hepatobiliary Pancreatic Cancer

This study aims to evaluate the role of ct-DNA, PVT1 and reactive oxygen species (ROS) as biomarkers in the diagnosis, treatment and recurrence monitoring of gastrointestinal and hepatobiliary pancreatic cancer.

Chemoradiation-Induced Nausea and Emesis: Quality of Life

The primary objectives of this study are:

1. To assess the preferences of cancer patients scheduled to receive chemoradiation and caregiver controls for side-effects of chemoradiation.

1. To compare preferences of cancer patients to those of healthy individuals.
2. To compare how patients' preferences for side-effects of chemoradiation change over time.
2. To longitudinally assess the quality of life of cancer patients scheduled to receive chemoradiation.
3. To determine the impact of nausea and vomiting associated with chemoradiation on patients' quality of life and evaluate potential change throughout the duration of chemoradiation treatment.

Dose-Escalation Study of Intensity-Modulated Radiotherapy(IMRT)in Patients With Unresectable Pancreatic Cancer

This is a research study for pancreatic cancer. One way of improving the results of current standard treatments is to try new approaches. This study will examine the use of a more advanced radiation therapy technique, called intensity modulated radiation therapy (IMRT), with chemotherapy. All subjects on this study will be treated with gemcitabine. This chemotherapy agent has been used for patients with pancreatic cancer. The researchers have already done studies using radiation therapy and gemcitabine. They want to build on the information they have from this previous research. The researchers want to find the best dose of IMRT that can be given at the same time that patients are receiving gemcitabine. To do this, they will vary the total dose of radiation received by patients on this study based on the information they have available from previously treated patients. The goal of the research is to identify the highest dose of IMRT that can be given at the same time as the chemotherapy without causing severe side effects.

Epacadostat, Pembrolizumab, and CRS-207, With or Without CY/GVAX Pancreas in Patients With Metastatic Pancreas Cancer

This study will enroll patients who have metastatic pancreatic cancer and have progressed on prior chemotherapy.

Part 1 (dose escalation) participants will receive epacadostat/pembrolizumab/cyclophosphamide(CY)/GVAX pancreas vaccine followed by epacadostat/pembrolizumab/CRS-207, Part 1X (dose escalation) participants will receive epacadostat/pembrolizumab/CRS-207. Part 2X (dose expansion) participants will receive epacadostat/pembrolizumab/CRS-207.

The primary objectives of this study are to determine the recommended dose of epacadostat in this combination and assess survival of subjects in both treatment groups.

Ultra Sound Guided Fine Needle Aspiration Cytology (FNAC) of Liver and Pancreas Tumours

Patients with tumors in liver or pancreas are randomized to ultrasound (UL)-guided FNAC biopsies with guidance method or UL-guided FNAC biopsies with free-hand method.

Laboratory Assay in Determining Cancer Resistance in Patients With Metastatic Cancer and in Healthy Participants

RATIONALE: Studying samples of blood and tissue in the laboratory from patients with cancer and from healthy participants may help doctors learn more about cancer.

PURPOSE: This laboratory study is looking at an assay in determining cancer resistance in patients with metastatic cancer and in healthy participants.
