Background: A new cancer therapy takes white blood cells from a person, grows them in a lab, genetically changes them, then gives them back to the person. Researchers think this may help attack tumors in people with certain cancers. It is called gene transfer using anti-KRAS G12D mTCR cells. Objective: To see if anti-KRAS G12D mTCR cells are safe and cause tumors to shrink. Eligibility: Adults ages 18-72 who have cancer with a molecule on the tumors that can be recognized by the study cells Design: Participants will be screened with medical history, physical exam, scans, photography, and heart, lung, and lab tests. An intravenous (IV) catheter will be placed in a large vein in the chest. Participants will have leukapheresis. Blood will be removed through a needle in an arm. A machine will divide the blood and collect white blood cells. The rest of the blood will be returned to the participant through a needle in the other arm. A few weeks later, participants will have a hospital stay. They will: Get 2 chemotherapy medicines by IV over 5 days. Get the changed cells through the catheter. Get up to 9 doses of a medicine to help the cells. They may get a shot to stimulate blood cells. Recover in the hospital for up to 3 weeks. They will provide blood samples. Participants will take an antibiotic for at least 6 months. Participants will have several follow-up visits over 2 years. They will repeat most of the screening tests and may have leukapheresis. Participants blood will be collected for several years.

This phase IIA trial investigates the side effects of Ad5.F35-hGCC-PADRE vaccine and to see how well it works in treating patients with gastrointestinal adenocarcinoma. Ad5.F35-hGCC-PADRE vaccine may help to train the patient's own immune system to identify and kill tumor cells and prevent it from coming back.

RGX-202-01 (ompenaclid) is a Phase 1, first-in-human, dose escalation and expansion study of RGX-202-01 as a single agent and in combination with FOLFIRI +/- bevacizumab. RGX-202-01 is a small molecule inhibitor of the creatine transporter SLC6a8, a novel metabolic target that drives gastrointestinal cancer progression. During the dose escalation stage, multiple doses of orally administered RGX-202-01 with or without FOLFIRI +/- bevacizumab (single agent or combination therapy) will be evaluated in patients with advanced gastrointestinal tumors (i.e., locally advanced and unresectable, or metastatic) who have had PD on available standard systemic therapies or for which there are no standard systemic therapies of relevant clinical impact. In the expansion stage: Patients with colorectal cancer (CRC) RAS Mutant will be treated at the optimal dose.

A clinical trial to assess the safety and efficacy of genetically-engineered, neoantigen-specific Tumor Infiltrating Lymphocytes (TIL) in which the intracellular immune checkpoint CISH has been inhibited using CRISPR gene editing for the treatment of Gastro-Intestinal (GI) Cancer.

This phase II trial studies how well giving oxaliplatin over 6 hours works in treating nerve damage in patients with gastrointestinal cancers. Oxaliplatin can cause side effects such as nerve damage that may delay or reduce the dose of oxaliplatin. Giving oxaliplatin over a longer period of time (6 hours) may prevent or delay the development of nerve damage, which may keep patients on standard doses of chemotherapy longer, without having to delay treatment.

The use of clips to completely clip mucosal defects after ESD/EMR can reduce postoperative adverse events, but the rate of incomplete mucosal defects closure is high. The continuous suture technique can completely close the mucosal defects by using surgical sutures and clips to suture the mucosal defects after ESD/EMR. In this study, a clinical randomized controlled study was conducted in our hospital. A total of 62 enrolled patients were divided into two groups, 31 patients were set as a treatment group using continuous suture technique to close post-EMR/ESD mucosal/submucosal defects, the rest patients were set as a control group using clips. The safety and effectiveness of continuous sutures and clips to clamp the post-EMR/ESD mucosal/submucosal defect were compared in the two groups. The complete mucosal/submucosa defects closure rates were the primary outcome.

This study is to evaluate the safety and antitumor activity of EMB-01 in advanced/metastatic gastrointestinal cancers, including gastric cancer, hepatocellular cancer, cholangiocarcinoma and colorectal cancer.

The primary objective of this study is to assess the safety and tolerability of E7386 in participants with solid tumor including CRC.

This trial studies tucatinib to find out if it is safe when given with trastuzumab and other anti-cancer drugs (pembrolizumab, FOLFOX, and CAPOX). It will look at what side effects happen when participants take this combination of drugs. A side effect is anything the drug does other than treating cancer. It will also look at whether tucatinib works with these drugs to treat certain types of cancer. The participants in this trial have HER2-positive (HER2+) cancer in their gut, stomach, intestines, or gallbladder (gastrointestinal cancer).
