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 SGN-CEACAM5C in Adults With Advanced Solid Tumors
This clinical trial is studying advanced solid tumors. Solid tumors are cancers that start in a part of your body like your lungs or liver instead of your blood. Once tumors have grown bigger in one place but haven't spread, they're called locally advanced. If your cancer has spread to other parts of your body, it's called metastatic. When a cancer has gotten so big it can't easily be removed or has spread to other parts of the body, it is called unresectable. These types of cancer are harder to treat. Participants in this study must have cancer that has come back or did not get better with treatment. Participants must have a solid tumor cancer that can't be treated with standard of care drugs. This clinical trial uses an experimental drug called PF-08046050. PF-08046050 is a type of antibody-drug conjugate or ADC. ADCs are designed to stick to cancer cells and kill them. They may also stick to some normal cells. This study will test the safety of PF-08046050 in participants with solid tumors that are hard to treat or have spread throughout the body. This study has 5 different study parts. Part A and Part B of the study will find out how much PF-08046050 should be given to participants. Part C will use the information from Parts A and B to see if PF-08046050 is safe and if it works to treat certain solid tumor cancers. Part D and E of the study, together with information from Parts A and B, will find out how much PF-08046050 should be given in combination with other anti-cancer agents. Part E will use the information from Parts A, B, and D to see if PF-08046050 is safe in combination with other anti-cancer agents and if it works to treat a certain solid tumor.

Beamion BCGC-1: A Study to Find a Suitable Dose of Zongertinib Used Alone and in Combination With Other Treatments to Test Whether it Helps People With Different Types of HER2+ Cancer That Has Spread
This study is open to adults aged 18 years and older with different types of HER2+ cancer that has spread and cannot be removed by surgery. People can take part in this study if their tumours show HER2 aberrations and previous treatment was not successful. The purpose of this study is to find a suitable dose of zongertinib that people with different types of HER2+ cancer that has spread can tolerate best when taken together with trastuzumab deruxtecan (T-DXd), with trastuzumab emtansine (T-DM1), with trastuzumab and capecitabine, with zanidatamab, or with mFOLFOX6 (with or without trastuzumab). Another purpose is to check whether zongertinib alone and in combination with other treatments can make tumours shrink. Zongertinib inhibits HER2. HER2 causes cancer cells to grow. In this study, participants receive treatment in cycles. Study participants are treated with zongertinib alone or in combination with other treatments. This study has 2 parts. In Part 1, participants in different groups receive increasing doses of zongertinib. In Part 2, participants are put into different groups by chance. Each group receives a different dose of zongertinib. Every participant has an equal chance of being in each group. During the study, the participants visit the study site regularly. In this study, researchers want to find the highest dose of zongertinib that participants can tolerate when taken together with other treatments. To find this out, researchers look at certain severe health problems that a number of participants have. The doctors regularly check the size of the tumour with imaging methods (CT/MRI) during the study. The doctors also regularly check participants' health and take note of any unwanted effects.

A Study to Evaluate the Adverse Events, Efficacy, and Optimal Dose of Intravenous (IV) ABBV-400 in Combination With IV Fluorouracil, Leucovorin, and Budigalimab in Adult Participants With Locally Advanced Unresectable or Metastatic Gastric, Gastroesophageal Junction, or Esophageal Adenocarcinoma
Cancer is a condition where cells in a specific part of body grow and reproduce uncontrollably. The purpose of this study is to assess adverse events and change in disease activity when telisotuzumab adizutecan (ABBV-400) is given in combination with Fluorouracil, Leucovorin, and a programmed cell death receptor 1 (PD1) inhibitor Budigalimab. The combination (AFLB) will be given to adult participants to treat locally advanced unresectable or metastatic gastric, gastroesophageal junction, or esophageal adenocarcinoma (mGEA). Telisotuzumab Adizutecan (ABBV-400) and Budigalimab are investigational drugs being developed for the treatment of mGEA. Fluorouracil and Leucovorin are drugs approved for the treatment of mGEA. This study will be divided into two stages, with the first stage treating participants with increasing doses of ABBV-400 within the AFLB regimen until the dose reached is tolerable and expected to be efficacious. Participants will then be randomized into groups called treatment arms where one group will receive Budigalimab and FOLFOX (Fluorouracil, Leucovorin, and Oxaliplatin) . A further two treatment groups will receive AFLB, but with two optimized doses of ABBV-400 to allow for the best dose to be studied in the future. Approximately 180 adult participants with mGEA will be enrolled in the study in 51 sites worldwide. In the dose escalation stage, participants will be treated with increasing intravenous (IV) doses of telisotuzumab adizutecan (ABBV-400) within the AFLB regimen until the dose reached is tolerable and expected to be efficacious. In the dose optimization stage, participants will receive FOLFOX or receive AFLB, but with one of two optimized doses of ABBV-400. The study will run for a duration of approximately 6 years. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at an approved institution (hospital or clinic). The effect of the treatment will be frequently checked by medical assessments, blood tests, questionnaires and side effects.

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 Disitamab Vedotin With Other Anticancer Drugs in Solid Tumors
This clinical trial is studying solid tumor cancers. A solid tumor is one that starts in part of your body like your lungs or liver instead of your blood. Once they've grown bigger in one spot or spread to other parts of the body, they're harder to treat. This is called advanced or metastatic cancer. Participants in this study must have breast cancer or gastric cancer. Participants must have tumors that have HER2 on them. This allows the cancer to grow more quickly or spread faster. There are few treatment options for patients with advanced or metastatic solid tumors that express HER2. This clinical trial uses an experimental drug called disitamab vedotin (DV). Disitamab vedotin is a type of antibody drug conjugate or ADC. ADCs are designed to stick to cancer cells and kill them. This clinical trial uses a drug called tucatinib, which has been approved to treat cancer in the United States and some other countries. This drug is sold under the brand name TUKYSA®. This study will test how safe and how well DV with tucatinib works for participants with solid tumors. This study will also test what side effects happen when participants take these drugs. A side effect is anything a drug does to the body besides treating the disease.
