Autologous T-cells Genetically Engineered to Express Receptors Reactive Against KRAS Mutations in Conjunction With a Vaccine Directed Against These Antigens in Participants With Metastatic Cancer

Background: Many cancer cells produce substances called antigens that are unique to each cancer. These antigens stimulate the body s immune responses. One approach to treating these cancers is to take disease-fighting white blood cells from a person, change those cells so they will target the specific proteins (called antigens) from the cancer cells, and return them to that person s blood. The use of the white blood cells in this manner is one form of gene therapy. A vaccine may help these modified white cells work better. Objective: To test a cancer treatment that uses a person s own modified white blood cells along with a vaccine that targets a specific protein. Eligibility: Adults aged 18 to 72 years with certain solid tumors that have spread after treatment. Design: Participants will undergo leukapheresis: Blood is removed from the body through a tube attached to a needle inserted into a vein. The blood passes through a machine that separates out the white blood cells. The remaining blood is returned to the body through a second needle. Participants will stay in the hospital for 3 or 4 weeks. They will take chemotherapy drugs for 1 week to prepare for the treatment. Then their modified white cells will be infused through a needle in the arm. They will take other drugs to prevent infections after the infusion. The vaccine is injected into a muscle; participants will receive their first dose of the vaccine on the same day as their cell infusion. Participants will have follow-up visits 4, 8, and 12 weeks after the cell infusions. They will receive 2 or 3 additional doses of the boost vaccine during these visits. Follow-up will continue for 5 years, but participants will need to stay in touch with the gene therapy team for 15 years. ...

Acquisition of Blood and Tumor Tissue Samples From Patients With Gastrointestinal Cancer

Background: \- Gastrointestinal cancers can occur in the throat, stomach, gallbladder, liver, pancreas, and colon. Researchers are interested in evaluating how active the immune system is in trying to fight the cancer by studying blood and tumor tissue donated from individuals who have been diagnosed with gastrointestinal cancers. Objectives: \- To collect blood and tumor samples from individuals who have been diagnosed with gastrointestinal cancers in order to study the immune system s response to the cancer. Eligibility: \- Individuals at least 18 years of age who have been diagnosed with throat, stomach, gallbladder, liver, pancreatic, or colon cancer, and are scheduled to be treated at the National Institutes of Health. Design: * The study will require at least one but no more than four visits to the National Institutes of Health Clinical Center. * Participants will be screened with a physical examination and medical history, and will provide a baseline blood sample for study. * Participants will provide additional blood samples 2 and 4 months after the baseline sample, as well as a final sample at the completion of the treatment protocol. * Participants will provide tumor tissue samples only if they undergo a surgical procedure related to the treatment for their gastrointestinal cancer. * No treatment will be provided as part of this protocol.

Individual Response to Hyperthermic Intraperitoneal Chemotherapy (HIPEC) Treatment of Peritoneal Carcinomatosis From Peritoneal Mesothelioma or Atypical Mesothelial Proliferation or From Ovarian, Colorectal, or Appendiceal Histologies

Background: Cytoreductive surgery (CRS) removes tumors in the abdomen. HIPEC is hyperthermic (heated) chemotherapy that washes the inside of the abdomen. CRS with HIPEC may help people with peritoneal carcinomatosis. These are tumors that have spread to the lining of the abdomen from other cancers. Researchers think they can improve the results of CRS with HIPEC treatment on these tumors by choosing the chemotherapy drugs used in HIPEC. Objective: To see if HIPEC after CRS can be improved, using either a model called the SMART (Sustained Microenvironment for Analysis of Resected Tissue) System or using 3-D cell culture (organoid) models, in order to test different chemotherapy drugs on tumors that were surgically removed prior to HIPEC treatment (these models are not attached to the body) versus tumors that were treated with HIPEC while still inside the body before being immediately surgically removed. Eligibility: Adults ages 18 and older who have peritoneal carcinomatosis that cannot be fully removed safely with surgery. Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Electrocardiogram (EKG) Computed tomography (CT) scan Other imaging scans, as needed Tumor biopsy, if needed Laparoscopy (small cuts are made in the abdomen, and a tube with a light and a camera is used to see the organs in the abdomen), if needed Participants will enroll in NIH protocol #13C0176. This allows their tumor samples to be used in future research. Some screening tests may be repeated in the study. Participants will have CRS. As many of their visible tumors will be removed as possible during surgery except for a few specific tumors left to receive the HIPEC treatment. Then they will receive HIPEC and the remaining tumors will be immediately removed. Participants will be in the hospital for 7-21 days after this surgery (CRS with HIPEC). Participants will give tumor, fluid samples (from the abdomen during surgery), blood, saliva, cheek swab, and stool for research. They will complete surveys about their health and quality of life. Participants with peritoneal mesothelioma (mesothelioma primary only) will have genetic (DNA) testing to determine clinical (CLIA level) germline BAP1 status for research use. Participants will have follow-up visits for up to 5 years from CRS with HIPEC. If there is disease progression, participants may have CRS with HIPEC again. Participants will then have follow-up visits for up to 5 years from the date of last CRS with HIPEC.

Prospective Procurement of Tumor Tissue to Identify Novel Therapeutic Targets and Study the Tumor Microenvironment

Background: Many advances have been made in cancer treatments, but more research is needed. Comparing samples of cancerous tissue to samples of normal, noncancerous tissues may help find differences between them. These differences may help researchers find new ways to treat cancer. Objective: To collect tissues and blood samples from people with known or suspected cancer. The samples will be used to help identify new targets for cancer treatments. Eligibility: People aged 18 years and older with a known or suspected cancer that requires surgery or biopsy. Design: Participants will be screened. They will answer questions about their health. They can do this on the phone or in person. Researchers will collect information from participants medical records. Data may include information about any prior or current cancers. Data about other medical conditions may also be collected. Participants will have blood drawn. Some of the blood will be tested for HIV and hepatitis B and C. Some of the blood will be used for genetic research. Participants will have tissue samples collected during surgeries or biopsies. These are procedures the participants would have had as part of their standard care. No new procedures will be done just for this study. Researchers may also seek out samples from prior procedures the participant had done. Participants will remain in the study for 6 months. They may have blood drawn again. Researchers may also collect tissue samples from any procedures performed during that time.

A Study to Test Different Doses of BI 765049 Alone and in Combination With Ezabenlimab in Asian People With Advanced Cancer (Solid Tumours) Positive for B7-H6

This is a study in adults from Asia with different types of advanced cancer (solid tumours). People can join the study if they have cancer of the stomach, large bowel and rectum, pancreas, liver, head and neck or non-small cell lung cancer. This is a study for people for whom previous treatment was not successful or no treatment exists. People can participate if their tumour has the B7-H6 marker. The purpose of this study is to find the highest dose of BI 765049 that people with advanced cancer can tolerate when taken (alone and) together with ezabenlimab. Another purpose is to check whether BI 765049 taken (alone and) together with ezabenlimab can make tumours shrink. Both medicines may help the immune system fight cancer. Participants can stay in the study up to 3 years, as long as they can tolerate it and can benefit from it. During this time, they visit the study site about every 3 weeks. At the study site they get BI 765049 alone or in combination with ezabenlimab as an infusion into a vein. BI 765049 is given in 3-week cycles, ezabenlimab is given once every 3 weeks. The doctors check the health of the participants and note any health problems that could have been caused by BI 765049 or ezabenlimab. Doctors regularly check the size of the tumour and check whether it has spread to other parts of the body.

EQUITY GI: A Prospective Study to Enhance Quality, Inclusivity, and Trial Participation in Black Patients With Gastrointestinal Cancer.

This research study is being conducted to improve the quality of care of participants who have a diagnosis of gastrointestinal cancer (anal, colon, rectal, esophageal, stomach, small bowel, appendix, pancreas, gall bladder, liver, neuroendocrine tumor of gastrointestinal origin). This study has 3 components as follows- 1. Ensuring appropriate biomarker testing and evidence-based care: Biomarkers are molecules in the tumor or blood that indicate normal or abnormal processes in participant's body and may indicate an underlying condition or disease. Various molecules, such as DNA (genes), proteins, or hormones, can serve as biomarkers since they all indicate something about participant's health. Biomarker testing can also help choose participant's treatment. Additionally, a tumor board will be conducted periodically to provide treatment recommendations to participant's treating physician. Participants will receive standard-of-care treatment if participant enroll in this study. Participant will not receive any experimental treatment. 2. Assistance with clinical trial enrollment. The study team will help participants enroll in a clinical trial appropriate for participant's condition. However, enrolling in a clinical trial is totally up to the participant. 3. Health literacy: The study team will provide information relevant to participant's diagnosis to enrich participant's understanding of participant's condition and treatment. Investigator will provide questionnaires to assess participant's understanding before and after participant's have been provided with educational/informational material appropriate for participant's diagnosis.
