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.

Nivolumab and Ipilimumab in Treating Patients With Esophageal and Gastroesophageal Junction Adenocarcinoma Undergoing Surgery

This phase II/III trial studies the usefulness of treatment with nivolumab and ipilimumab in addition to standard of care chemotherapy and radiation therapy in patients with esophageal and gastroesophageal junction adenocarcinoma who are undergoing surgery. Immunotherapy with antibodies, such as nivolumab and ipilimumab, may remove the brake on the body's immune system and may interfere with the ability of tumor cells to grow and spread. Chemotherapy and radiation therapy may reduce the tumor size and the amount of normal tissue that needs to be removed during surgery. A combined treatment with nivolumab and ipilimumab, chemotherapy, and radiation therapy might be more effective in patients with esophageal and gastroesophageal junction adenocarcinoma who are undergoing surgery.

NBTXR3, Chemotherapy, and Radiation Therapy for the Treatment of Esophageal Cancer

The purpose of this Phase I study is to determine the recommended phase 2 dose (RP2D) and safety profile of NBTXR3 activated by radiation therapy with concurrent chemotherapy for the treatment of patients with esophageal adenocarcinoma. NBTXR3 is a drug that when activated by radiation therapy, may cause targeted destruction of cancer cells. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Chemotherapy drugs, such as oxaliplatin, fluorouracil, capecitabine, docetaxel, paclitaxel, and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving NBTXR3 activated by radiation therapy with concurrent chemotherapy may help control the disease.

Pathological Response to Perioperative FLOT in Gastric Adenocarcinoma

Perioperative chemotherapy with the FLOT regimen (5-fluorouracil, leucovorin, oxaliplatin and docetaxel) is a standard treatment for resectable gastric and gastroesophageal junction adenocarcinoma. However, real-world studies have reported lower pathological complete response rates than the pivotal trials, and Colombian evidence is limited, coming mainly from surgical series focused on operative outcomes. This descriptive retrospective study will review the medical records of adults with stage I to III gastric or gastroesophageal junction adenocarcinoma who started perioperative FLOT at Fundación Santa Fe de Bogotá (Bogotá, Colombia) between January 1, 2021 and December 31, 2025 (approximately 90 patients). It will describe pathological response (tumor regression grade by the Mandard system and pathological complete response), grade 3-4 toxicity, dose modifications, treatment adherence and completion, recurrence and overall survival. The investigators will not assign or modify any treatment, and no hypothesis testing will be performed.

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.

Comparison of In-Home Versus In-Clinic Administration of Subcutaneous Nivolumab Through Cancer CARE (Connected Access and Remote Expertise) Beyond Walls (CCBW) Program

This phase II trial compares the impact of subcutaneous (SC) nivolumab given in an in-home setting to an in-clinic setting on cancer care and quality of life. Currently, most drug-related cancer care is conducted in clinic type centers or hospitals which may isolate patients from family, friends and familiar surroundings for many hours per day. This separation adds to the physical, emotional, social, and financial burden for patients and their families. Traveling to and from medical facilities costs time, money, and effort and can be a disadvantage to patients living in rural areas, those with low incomes or poor access to transport. Studies have shown that cancer patients often feel more comfortable and secure being cared for in their own home environments. SC nivolumab in-home treatment may be safe, tolerable and/or effective when compared to in-clinic treatment and may reduce the burden of cancer and improve the quality of life in cancer patients.

Study of Cabozantinib Alone or in Combination With Atezolizumab to Subjects With Locally Advanced or Metastatic Solid Tumors

This is a multicenter Phase 1b, open-label study to assess safety, tolerability, preliminary efficacy, and pharmacokinetics (PK) of cabozantinib taken in combination with atezolizumab in subjects with multiple tumor types, including advanced urothelial carcinoma (UC) (including bladder, renal pelvis, ureter, urethra), renal cell carcinoma (RCC), castration-resistant prostate cancer (CRPC), non-small-cell lung cancer (NSCLC), triple negative breast cancer (TNBC), ovarian cancer (OC), endometrial cancer (EC), hepatocellular cancer (HCC), gastric cancer/gastroesophageal junction cancer/lower esophageal cancer (GC/GEJC/LEC), colorectal cancer (CRC), head and neck (H\&N) cancer, and differentiated thyroid cancer (DTC). The study consists of two stages: in the Dose Escalation Stage, an appropriate recommended cabozantinib dose for the combination with standard dosing regimen of atezolizumab will be established; in the Expansion Stage, tumor-specific cohorts will be enrolled in order to further evaluate the safety and efficacy of the combination treatment in these tumor indications. Three exploratory single-agent cabozantinib (SAC) cohorts may also be enrolled with UC, NSCLC, or CRPC subjects. One exploratory single-agent atezolizumab (SAA) cohort may also be enrolled with CRPC subjects. Subjects enrolled in the SAC cohorts and SAA cohort may receive combination treatment with both cabozantinib and atezolizumab after they experience radiographic progressive disease per the Investigator per RECIST 1.1. Due to the nature of this study design, some tumor cohorts may complete enrollment earlier than others.

Silent Evaluation of DeepTRG for Assessing Tumor Response After Preoperative Treatment in Stomach and Gastroesophageal Junction Cancer

This study will evaluate whether an artificial intelligence (AI) system called DeepTRG can reliably assess cancer tissue removed during surgery after treatment given before surgery. It will include adults with stomach cancer or cancer at the junction between the stomach and the food pipe who have received treatment before surgery. Pathologists are doctors who examine tissue to diagnose disease. After cancer surgery, they assess how much living cancer remains and whether cancer is present in nearby lymph nodes. DeepTRG analyzes digital images of tissue slides to measure remaining cancer and describe tissue changes, such as scarring and inflammation. It combines information from the original tumor site and lymph nodes to produce a structured assessment. The main question is: \* How often can DeepTRG complete the required assessment and produce a clear result without a person correcting the AI analysis? The study will also examine: * How closely the system's measurements agree with assessments made by independent expert pathologists. * How accurately it detects remaining cancer, including small amounts of cancer and cancer in lymph nodes. * How long the analysis takes and how often it fails or produces an uncertain result. * Whether its performance differs across treatment types and cancer tissue types. This study will take place at the Fourth Hospital of Hebei Medical University in China. Eligible patients will be enrolled consecutively. Researchers will use tissue collected during the patients' planned surgery. No additional surgery or biopsy is required for this study. DeepTRG will run in the background in "silent mode." The doctors responsible for the patients' routine pathology reports and treatment decisions will not receive its results. Patients will continue to receive usual care. The AI model and its grading rules will be fixed before validation begins. Independent expert pathologists will assess the tissue without seeing the AI results. Researchers will then compare the expert assessments, routine pathology reports, and DeepTRG outputs. Cases with poor-quality images, failed analyses, or uncertain outputs will remain part of the assessment of how reliably the system works. Researchers will also collect information about subsequent treatment, cancer recurrence, and survival during follow-up. The initial analysis will focus on feasibility and measurement performance. A separate future study would be needed to determine whether using DeepTRG in clinical care improves doctors' decisions or patient outcomes.
