Robotic Cytoreduction and Hyperthermic Intraperitoneal Chemotherapy for Treatment of Gastric Cancer With Limited Peritoneal Metastasis, ROBO-CHIP Study

This phase II clinical trial tests how well robotic cytoreduction and hyperthermic intraperitoneal chemotherapy (HIPEC) in treating patients with gastric cancer that has spread to the tissue that lines the wall of the abdominal cavity (peritoneum). Gastric cancer is the third leading cause of cancer related deaths worldwide and peritoneal metastasis are found in 30% of patients at time of diagnosis. Patients with peritoneal metastasis have poor survival rates. Traditional surgery is done with a large incision and has a high complication rate and longer hospital stays. Robot assisted (robotic) cytoreduction is a surgical option that uses small incisions and there is less risk of complications. HIPEC involves infusing heated chemotherapy into the abdominal cavity during surgery. Robotic cytoreduction together with HIPEC may improve recovery and decrease complications after surgery.

A Study of Disitamab Vedotin, Tunlametinib, and PD-1 Antibody for Advanced Gastric Cancer

The goal of this clinical trial is to learn if the combination of disitamab vedotin, tunlametinib, and a PD-1 antibody works to treat HER2-overexpressing advanced gastric cancer in patients who have already received at least two lines of prior therapy. It will also learn about the safety of this combination therapy. The main questions it aims to answer are: What is the objective response rate (tumor shrinkage) in participants receiving this combination? What medical problems (side effects) do participants have when taking this combination? Researchers will evaluate the efficacy and safety of disitamab vedotin combined with tunlametinib and a PD-1 antibody in patients with HER2-overexpressing advanced gastric cancer who have failed at least two lines of standard treatment. Participants will: Receive disitamab vedotin intravenously every 2 weeks and a PD-1 antibody intravenously once every 6 weeks. Take tunlametinib orally every 12 hours. Continue treatment until disease progression or unacceptable toxicity. Visit the clinic every 2 weeks for checkups, blood tests, and safety monitoring. Undergo tumor imaging assessments every 6 weeks to evaluate treatment response.

Testing the Addition of Paclitaxel Administered Into the Abdominal Cavity Combined With Chemotherapy for Patients With Gastric Cancer Spread to the Abdominal Cavity

This study is being done to answer the following questions: Can we lower the chance of your gastric cancer from growing or spreading by administering paclitaxel chemotherapy directly into your abdominal cavity in addition to chemotherapy given through a vein in your arm? Will administering paclitaxel chemotherapy directly into your abdominal cavity, in addition to chemotherapy given through a vein in your arm help you live longer? We are doing this study because we want to find out if this approach is better or worse than the usual approach for your gastric cancer. The usual approach is defined as care most people get for gastric cancer. If you decide to take part in this study, you will first receive a surgical procedure called a diagnostic laparoscopy. This will help the study doctors learn more about your gastric cancer. Laparoscopy is a minimally invasive surgery for which you will be placed under general anesthesia. Then the surgeon will make small incisions (5mm) on your belly through which a camera and thin instruments are introduced to evaluate the abdomen. This procedure takes about 1 hour to complete. Your study group will be assigned during the surgery. The study groups are described further in the 'What are the study groups?' section below. If you are placed into the study group 1, you will not have an intraperitoneal port (a small device which is placed under the skin and fat of your upper abdomen and a tube that is placed into the abdomen). If you are placed into the study group 2, you will have an intraperitoneal port placed. The reason is that in addition to standard chemotherapy, which is given through a vein in your arm, this port will be used to deliver the medication paclitaxel directly inside your abdomen when you are ready to start study treatment. It is important to know that you will not know your study group until after the surgery is over. This is because information that is learned during the surgery will help determine which study group you are put in. Once you have fully healed from this surgery, you will start study treatment. Depending on which study group you are assigned, you will either receive a standard chemotherapy regimen (the regimen will be chosen by you and your doctor) if you are in study group 1, or paclitaxel through a tube in your belly plus chemotherapy given through a vein in your arm if you are in study group 2. All participants will get treatment for three (3) months after which you will undergo reevaluation. If the disease is under control or responding to treatment, you may continue the assigned treatment until your disease gets worse, the side effects become too severe, or you may be offered a surgical procedure to remove the cancer if the amount of disease is low and can be completely removed as determined by a surgeon. There is a very small chance that during the laparoscopy surgical procedure, the doctor might find something called "intra-abdominal adhesions". These are areas where the stomach has healed previously and created scar tissue. If this scar tissue prevents the surgeon from being able to place a port in the correct area, you would be ineligible to receive the study treatment. If this happens, you may still receive standard of care therapy after your surgery, but you will not be able to continue on the study. If you have more questions about this, you can ask your surgeon or the study team to help. After you finish your study treatment, your doctor or study team will watch you for side effects. They will continue to follow your condition every three (3) months during the first two (2) years, then every six (6) months until year 5. You may be reevaluated with Chest/Abdomen/Pelvis scans every three-six (3-6) months for up to five (5) years if decided by your doctor.

A Study of ASP2138 Given by Itself or Given With Other Cancer Treatments in Adults With Stomach Cancer, Gastroesophageal Junction Cancer, or Pancreatic Cancer

Claudin 18.2 protein, or CLDN18.2 is a protein found on cells in the digestive system. It is also found on some tumors. Researchers are looking at ways to attack CLDN18.2 to help control tumors. ASP2138 is thought to bind to CLDN18.2 and a protein on a type of immune cell called a T-cell. This "tells" the immune system to attack the tumor. ASP2138 is a potential treatment for people with stomach cancer, gastroesophageal junction cancer (GEJ cancer) or pancreatic cancer. GEJ is where the tube that carries food (esophagus) joins the stomach. Before ASP2138 is available as a treatment, the researchers need to understand how it is processed by and acts upon the body. In this study, ASP2138 will either be given by itself, or given together with standard treatments for gastric, GEJ and pancreatic cancer. Pembrolizumab and mFOLFOX6, and ramucirumab and paclitaxel are standard treatments for gastric and GEJ cancer. mFOLFIRINOX is a standard treatment for pancreatic cancer. This information will help find a suitable dose of ASP2138 given by itself and together with the standard cancer treatments and to check for potential medical problems from the treatments. The main aims of the study are: * To check the safety of ASP2138 and how well people can tolerate medical problems during the study. * To find a suitable dose of ASP2138 to be used later in the study. * These are done for ASP2138 given by itself and when given together with the standard cancer treatments. Adults 18 years or older with stomach cancer, GEJ cancer, or pancreatic cancer can take part. Their cancer is locally advanced unresectable or metastatic. Locally advanced means the cancer has spread to nearby tissue. Unresectable means the cancer cannot be removed by surgery. Metastatic means the cancer has spread to other parts of the body. There should also be the CLDN18.2 marker in a tumor sample. People cannot take part if they need to take medicines to suppress their immune system, have blockages or bleeding in their gut, have specific uncontrollable cancers, have specific infections, have a condition such as hemophagocytic lymphohistiocytosis (HLH) which is when the body over-reacts to a "trigger" such as infection, or have a specific heart condition ("New York Heart Association Class III or IV"). Phase 1: Lower to higher doses of ASP2138 * ASP2138 is either given through a vein (intravenous infusion) or just under the skin (subcutaneous injection). * Different small groups are given lower to higher doses of ASAP2138. * ASP2138 is either given by itself, or given with 1 of 3 standard treatments: * Pembrolizumab and mFOLFOX6 (first treatment for gastric GEJ cancer) * Ramacirumab and paclitaxel (Second treatment for gastric or GEJ cancer) * ASP2138 with mFOLFIRINOX (first treatment for pancreatic cancer) Phase 1b: doses of ASP2138 worked out from Phase 1 * ASP2138 is either given through a vein or just under the skin. This depends on the findings from Phase 1. * People with gastric cancer, GEJ cancer or pancreatic cancer are given doses of ASP2138, worked out from Phase 1. * This includes doses of ASP2138 given by itself and ASP2138 given with the standard cancer treatments. * The standard cancer treatments given depends on the type of cancer they have. End of treatment visit: This is 7 days after final dose of study treatment or if the study doctor decides to stop the person's treatment. People who have locally advanced unresectable pancreatic cancer will not receive ASP2138 by itself.
