2 Clinical Trials for Various Conditions
Background: - Pancreatic cancer is difficult to treat because by the time most cases are diagnosed, the tumors are too large to be removed surgically. Standard intravenous chemotherapy may shrink some of the tumor, but even with chemotherapy only about 25 percent of patients will live for 1 year following diagnosis. Several preliminary studies have shown that it is safe to give chemotherapy directly into the pancreas in the area of the tumor, and that giving gemcitabine over a longer period increases the amount of drug that is available to the tumor. Researchers are interested in studying whether giving the approved pancreatic cancer chemotherapy drug gemcitabine directly into the pancreas in the area of the cancer and at a slow rate of infusion is a safe and effective treatment. Objectives: - To test the safety and effectiveness of administering gemcitabine directly to a pancreatic tumor at a slow rate of infusion. Eligibility: - Individuals at least 18 years of age who have been diagnosed with pancreatic cancer that is currently too large to be removed surgically but has not yet spread to other organs. Design: * Participants will be screened with a full medical history and physical examination, blood and urine tests, and imaging studies. * Participants will undergo pancreatic angiography and embolization, during which a catheter will be threaded into the blood vessels near the pancreas and a contrast dye will be used to show the blood vessels supplying the tumor. These blood vessels will then be surgically closed off. * After the embolization, gemcitabine will be given as an infusion into the area around the tumor over 24 hours. * Participants will return to the clinical center every 2 weeks after the first infusion for additional infusions of gemcitabine, using the same procedures as above. Participants will be monitored with frequent blood tests and imaging studies. * Two weeks after the fourth treatment (course 1), participants will have more imaging studies, a physical examination, and blood tests. If the tumor is shrinking, participants will have two more courses of treatment (eight more infusions of gemcitabine). * Participants will have followup visits every 3 months for 2 years following the last treatment and then every 6 months.
Background: Fewer than 10 percent of people with pancreas cancer can have surgery. Surgery gives the best outcome. Radiation therapy is usually used to make surgery possible. But it does not work for most people. Adding immunotherapy might help. Objective: To find a safe combined dose of Bintrafusp Alfa (M7824), NHS-IL12 (M9241, and radiation and to see if it causes pancreas cancer tumors to shrink. Eligibility: People ages 18 and older who have pancreas cancer and cannot have curative surgery Design: Participants will be screened under protocol 01-C-0129 with: Medical history Physical exam Heart, urine, and blood tests Scans. For this, participants will lie in a machine that takes pictures of the body. They may receive a contrast agent by vein. Possible tumor biopsy Participants will take the study drugs either alone or with radiation. They will get M7824 by vein every 2 weeks. They will get M9241 injected under the skin every 4 weeks. Participants who get radiation will get it 5 days in a row the first month. Participants will have visits every 2 weeks. They will repeat screening tests. If participants tumors shrink, they will have surgery. If their whole tumor is removed, they will stop treatment. They will otherwise continue treatment as long as they can tolerate it and it is helping them. Participants will have visits 1 week and 1 month after they stop treatment. Then they will be contacted by phone or email for life. If they stop treatment for a reason other than their disease getting worse, they will have scans every 12 weeks.
