To evaluate the clinical efficacy of perioperative treatment with S-1 + oxaliplatin (SOX)+ HLX10 compared with SOX as the control in patients with cT3-4N1-3M0 PD-L1-positive (CPS ≥ 5) locally advanced gastric adenocarcinoma or gastroesophageal junction adenocarcinoma, in a placebo-controlled, double-blind, randomized phase II investigator-initiated clinical study.

Study of Denikitug (GS-1811) Given Alone or With Nivolumab or Chemotherapy in Adults With Metastatic Gastric, Gastroesophageal Junction (GEJ), and Esophageal Adenocarcinomas

The goal of this clinical study is to learn more about the study drug, Denikitug (DEN, GS-1811), to evaluate the efficacy and safety of Denikitug Monotherapy and Denikitug-based combinations in in participants with human epidermal growth factor receptor 2 (HER2)-Negative, unresectable, recurrent, and/or metastatic, gastroesophageal junction (GEJ), and esophageal adenocarcinomas. The primary objective of this study is to assess the effect of DEN as a monotherapy or in combination with nivolumab (NIVO) or ramucirumab (RAM) and paclitaxel (PAC) on objective response rate (ORR) as assessed by the investigator according to Response Evaluation Criteria in Solid Tumors (RECIST Version1.1).

Molecular Characterization of Tumor-Microenvironment Interactions to Predict Drug Resistance in Gastric and GEJ Adenocarcinoma

Surgical resection remains the only curative option for resectable gastric cancer, but perioperative FLOT chemotherapy is associated with substantial rates of chemoresistance and recurrence, largely driven by marked tumor heterogeneity. Recent data from the MATTERHORN phase III trial have shown that adding durvalumab to perioperative FLOT improves pathological complete response and survival, supporting this combination as a new standard of care for resectable gastric and gastroesophageal junction adenocarcinoma. This observational multicenter study aims to characterize angiogenic and immune profiles within the tumor microenvironment and peripheral blood, in order to identify cellular and molecular signatures associated with response or resistance to perioperative FLOT plus durvalumab. Longitudinal biospecimen collection (PBMCs, serum, plasma, endoscopic biopsies, surgical specimens) will be integrated with multiparametric flow cytometry, single-cell transcriptomics and TCR/BCR sequencing, immunohistochemistry, pathomics and multiplex immunoassays, to provide mechanistic insights and potential predictive biomarkers.

Sac-TMT Combined With Fruquintinib as Second-Line Treatment in Patients With Advanced Gastric/Gastroesophageal Junction Adenocarcinoma

This is a phase 2 multicenter study that will evaluate the safety and efficacy of sacituzumab tirumotecan (Sac-TMT) plus fruquintinib for the treatment of participants with locally advanced or metastatic gastric (G) or gastroesophageal junction (GEJ) adenocarcinoma who have failed 1 prior line of therapy.

Phase 1/2 Study of BHB810 in Advanced Gastric and GEJ Adenocarcinoma

This study is looking at how safe BHB810 is in adults with gastric and gastroesophageal adenocarcinoma (GEJ). The purpose of this study is also to look at: how well the study drug works, how the study drug moves into, through, and out of the body, and how your body reacts to the study drug. Participants will get an IV infusion of BHB810 every 2 weeks while on study treatment.

A Study of IDE892 as Monotherapy and Combination in MTAP-deleted Advanced Solid Tumors

This is a multicenter clinical study to evaluate the safety, efficacy, and Pharmacokinetics (PK) of IDE892 as monotherapy and in combination with other agents including IDE397 in participants with methylthioadenosine phosphorylase (MTAP)-deleted advanced solid tumors within indications of interest.

A Study of Pembrolizumab With Trastuzumab and Chemotherapy in People With Esophagogastric Cancer

The purpose of this study to find out whether adding trastuzumab and pembrolizumab to standard chemotherapy is an effective treatment for resectable HER2+ esophagogastric cancer.

HIPEC Priming Followed by Serplulimab Plus SOX/XELOX in Locally Advanced Gastric Cancer

Patients with locally advanced gastric cancer (LAGC), particularly those with serosal invasion, remain at high risk of peritoneal recurrence despite standard perioperative treatment. Hyperthermic intraperitoneal chemotherapy (HIPEC) may eradicate free intraperitoneal tumor cells and microscopic peritoneal disease while potentially enhancing systemic anti-tumor immune activation. This is a prospective, single-center, single-arm exploratory study evaluating a HIPEC priming strategy followed by serplulimab-based neoadjuvant therapy in patients with locally advanced gastric cancer (cT3-4aN+M0). Eligible patients will undergo diagnostic laparoscopy confirming no visible peritoneal metastasis (P0) and negative peritoneal cytology (CY0), followed by docetaxel-based HIPEC. After recovery from HIPEC, patients will initially receive one cycle of serplulimab combined with fluoropyrimidine monotherapy (S-1 or capecitabine), followed by subsequent cycles of serplulimab combined with SOX/XELOX chemotherapy prior to radical gastrectomy. The primary endpoints are pathological complete response (pCR) rate and major pathological response (MPR) rate. Secondary endpoints include R0 resection rate, objective response rate (ORR), peritoneal recurrence-free survival (PRFS), overall survival (OS), and safety.

Tadalafil Effect + Chemotherapy in Resectable Gastric/GEJ Cancer

The goal of this clinical trial is to assess the ability of Tadalafil alone and in combination with neoadjuvant FLOT (5-Fluorouracil, Oxaliplatin, and Docetaxel) chemotherapy to suppress myeloid derived suppressor cells (MDSCs) in patients with resectable gastric or gastroesophageal junction adenocarcinoma. Resectable means the tumor may be removed through surgical intervention. Neoadjuvant chemotherapy is chemotherapy received before the primary course of treatment i.e.surgical intervention. The main questions it aims to answer are: * Is Tadalafil treatment with FLOT feasible and safe? * How does tadalafil treatment with FLOT affect the tumor microenvironment (TME)? * Will 8 weeks of neoadjuvant exposure to tadalafil with chemotherapy reduce MDSCs in the TME? Participants will receive Tadalafil for 14 days followed by combination of Tadalafil + FLOT for approximately 8 weeks as a part of standard of care neoadjuvant treatment in the window between cancer diagnosis and surgical intervention to remove their tumor. Tumor tissue, blood, and urine will be collected at the start of the study, after 2 weeks of treatment with Tadalafil alone, and around the time of surgical intervention. Saliva will also be collected at the start of the study.

Aldesleukin With Nivolumab and Standard Chemotherapy for Treatment of Gastric Cancer With Peritoneal Metastasis

This phase Ib trial test effects of aldesleukin in combination with nivolumab and standard chemotherapy in treating patients with gastric cancer that has spread to the tissue lining of the abdomen (peritoneal metastasis). Aldesleukin is similar to a protein that naturally exists in the body that stimulates the immune system to fight infections. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as leucovorin calcium, fluorouracil, and oxaliplatin, 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 aldesleukin in combination with nivolumab and standard chemotherapy may work better in treating patients with gastric cancer with peritoneal metastasis.

Hyperthermic Intraperitoneal Chemotherapy With Cisplatin and Paclitaxel for Gastric Cancer at High Risk of Peritoneal Recurrence

This phase II trial tests how well concentrating heated (hyperthermic) chemotherapy in the area that contains the abdominal organs (intraperitoneal \[IP\]) at the time of surgery works in treating patients with gastric or gastroesophageal junction adenocarcinoma at high risk of the cancer coming back to the abdominal cavity (peritoneal) after a period of improvement (recurrence). Recurrence in the peritoneum often occurs within the first 18 months after surgery. This is thought to be due to tumor cells that may scatter and spread during surgery. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of tumor cells. Paclitaxel is in a class of medications called antimicrotubule agents. It stops tumor cells from growing and dividing and may kill them. Paclitaxel alone and in combination with other chemotherapy agents have been shown to be effective treatments for gastric tumors. However, systemic delivery of these drugs has not been shown to be effective in treating peritoneal metastasis. Hyperthermic intraperitoneal chemotherapy (HIPEC) is a procedure that involves the infusion of a heated chemotherapy solution, such as cisplatin and paclitaxel, that circulates into the abdominal cavity. Giving HIPEC with cisplatin and paclitaxel at the time of surgery may reduce peritoneal recurrence in patients with gastric or gastroesophageal junction adenocarcinoma at high risk.

Testing Immunotherapy (Atezolizumab) With or Without Chemotherapy in Locoregional MSI-H/dMMR Gastric and Gastroesophageal Junction (GEJ) Cancer

This phase II trial compares atezolizumab in combination with chemotherapy (docetaxel, oxaliplatin, leucovorin calcium, fluorouracil, capecitabine) to atezolizumab alone for controlling the growth and/or spreading of the disease in patients with gastric or gastroesophageal junction (JEG) cancer that has not spread from where it first started (local) or only has spread to nearby lymph nodes or tissue (locoregional) and has high microsatellite instability (MSI-H) and mismatch repair deficiency (dMMR). The mismatch repair (MMR) system in the body corrects errors made during the copying of DNA and serves as a proofreading function. If this system isn't working correctly, mutations (changes) in DNA occur which can allow the cancer to grow or spread. This is called dMMR (deficient mismatch repair) . MSI-H describes cancer cells that have a high number of mutations within microsatellites. For example, microsatellite testing that shows mutations in 30% or more microsatellites is called microsatellite instability-high (MSI-H). Microsatellites are short, repeated sequences of DNA. There is evidence that MSI-H/ dMMR gastric or GEJ tumors respond well to immunotherapy. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Docetaxel is in a class of medications called taxanes. It stops tumor cells from growing and dividing and may kill them. Oxaliplatin is in a class of medications called platinum-containing antineoplastic agents. It damages the cell's DNA and may kill tumor cells. Capecitabine is in a class of medications called antimetabolites. It is taken up by tumor cells and breaks down into fluorouracil, a substance that kills tumor cells. Chemotherapy drugs such as leucovorin calcium and fluorouracil 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. Using atezolizumab as immunotherapy with and following chemotherapy versus atezolizumab alone prior to and after surgery may shrink or stabilize the tumor in patients with MSI-H/dMMR localized gastric or GEJ cancer and may increase the length of time after treatment that cancer does not come back or get worse.

JS107 in Combination With Toripalimab and Chemotherapy for the Treatment of CLDN18.2-positive Gastric or Gastroesophageal Junction Adenocarcinoma

This study is a multicenter, randomized, open-label, controlled Phase III clinical trial aimed at evaluating the efficacy and safety of JS107 combined with toripalimab XELOX versus sintilimab combined with XELOX as first-line treatment for patients with advanced G/GEJ adenocarcinoma. The research subjects were patients with unresectable locally advanced, recurrent or metastatic G/GEJ adenocarcinoma who were CLDN18.2-positive and HER2-negative and had not received systemic treatment before (except for neoadjuvant/adjuvant therapy that occurred more than 6 months after disease progression/recurrence from the last treatment). The study took BICR-PFS and OS as Dual primary endpoints.

A Study of ASP2138 Together With Chemotherapy and Pembrolizumab in Adults With Gastric Cancer

Claudin 18.2 or CLDN18.2 is a protein found on cells in the digestive system. It is also found in 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 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 gastric cancer (also known as stomach cancer) or gastroesophageal junction cancer (GEJ cancer). GEJ is where the tube that carries food (esophagus) joins the stomach. This study is for people with gastric or GEJ cancer that has spread nearby (locally advanced) and is not removable by surgery (unresectable), or has spread to other parts of the body (metastatic). It is for those whose cancer is human epidermal growth factor receptor 2 (HER2)-negative and CLDN18.2-positive. HER2-negative means the cancer does not have extra HER2 protein, so medicines that target HER2 do not work and are therefore not used. CLDN18.2-positive means people have a certain amount of CLDN18.2 proteins on their cancer cells. In this study, researchers want to learn if ASP2138 given together with standard treatments (chemotherapy and pembrolizumab) help people with HER2-negative and CLDN18.2-positive gastric or GEJ cancer. The main aim is to learn how long people who are given ASP2138 with chemotherapy and pembrolizumab live without their cancer getting worse, compared with placebo given with chemotherapy with or without pembrolizumab, and if they live for longer. Placebo looks like the study treatment but does not have any medicine in it. The main aim of this study is to check how well ASP2138 works when given together with chemotherapy and pembrolizumab compared with placebo plus chemotherapy with or without pembrolizumab. People aged 18 years or older with locally advanced unresectable or metastatic gastric or GEJ cancer can take part. Their tumor should be HER2-negative and CLDN18.2-positive. The study doctors will check people for any health conditions that can exclude them from taking part, interfere with the study procedures, or pose an unacceptable risk. This is a double-blind study. That means the people and the study doctors will not know who will receive which treatment. People will be assigned to one of 2 treatment groups by chance: Group A: People will receive ASP2138 along with chemotherapy and pembrolizumab. Group B: People will receive placebo along with chemotherapy, with or without pembrolizumab. People will keep receiving treatment until their cancer gets worse, they have medical problems that require stopping treatment, or a study rule says they must stop. There will be regular safety checks. People will continue to have scans of their tumor until their cancer becomes worse.

Emotional Distress and Pathologic Response in Locally Advanced Gastric/GEJ Adenocarcinoma

This is a single-center, prospective observational cohort study designed to evaluate the association between pretreatment emotional distress and pathologic response to perioperative immunotherapy in patients with locally advanced gastric or gastroesophageal junction adenocarcinoma. A total of 120 patients planned for neoadjuvant immunotherapy followed by curative surgery will be enrolled. Emotional distress will be assessed using the PHQ-9 and GAD-7 before treatment initiation and at prespecified time points during treatment. Participants will be classified into an emotional distress group or a non-emotional distress group according to predefined criteria. The primary endpoint is major pathological response (MPR). Secondary endpoints include pathological complete response (pCR), R0 resection rate, event-free survival (EFS), recurrence-free survival (RFS), and overall survival (OS). Exploratory analyses will assess dynamic changes in emotional distress and their associations with peripheral stress markers, peripheral immune markers, and tumor immune microenvironment features.

Oxaliplatin and Liposomal Irinotecan (Plus Trastuzumab for HER2-positive Disease) in Advanced Esophageal and Gastric Adenocarcinoma

This is an open label, phase II, multi-site trial evaluating the efficacy and safety of the combination of 5-FU, oxaliplatin, nal-IRI, and immunotherapy (plus trastuzumab for HER2-positive tumors) as first-line therapy for participants with advanced Esophageal and Gastric Adenocarcinoma (EGA). The investigators hypothesize that this drug combination will be better tolerated than current first-line chemotherapy combinations for this disease.

Objective Sleep Characteristics and Neoadjuvant Immunotherapy Response in Gastric/GEJ Cancer

This prospective observational study will enroll 120 patients with locally advanced gastric or gastroesophageal junction adenocarcinoma who are scheduled to receive neoadjuvant immunotherapy followed by radical surgery. Non-invasive objective sleep monitoring will be performed during the neoadjuvant treatment period to assess sleep characteristics, including sleep duration, sleep efficiency, device-estimated deep sleep proportion, nocturnal awakenings, sleep regularity, heart rate, and heart rate variability. The primary objective is to evaluate the association between objective sleep characteristics and major pathological response (MPR) after neoadjuvant immunotherapy. This study will not alter standard treatment decisions, surgical procedures, or perioperative management.

Evaluation of Esophagogastric Cancer Treatment With Nivolumab in Daily Clinical Practice

This study uses existing cancer registry and health record data to understand how nivolumab is used in routine care in the Netherlands for adults with advanced cancers of the esophagus, gastroesophageal junction, or stomach.

A Study of TRK-950 When Used in Combination With Ramucirumab and Paclitaxel in Patients With Gastric Cancer

This study will assess the efficacy, safety, optimal dose and ADA and NAbs development of TRK-950 at two separate dose levels in combination with ramucirumab and paclitaxel (RAM+PTX) as compared with RAM + PTX treatment alone in participants with gastric or gastro-esophageal junction (GEJ) adenocarcinoma.

Anti-PD-1 mAb Plus Metabolic Modulator in Solid Tumor Malignancies

Patients with histologically or cytologically confirmed advanced melanoma, renal cell carcinoma, NSCLC, HCC (Child Pugh Class A only), MSI-High solid tumors, Urothelial Cancer, GE junction/Gastric Adenocarcinoma, or HNSCC for which current standard of care treatment for their stage of disease would be with Pembrolizumab or Nivolumab monotherapy, who meet eligibility criteria will undergo a biopsy (core or excisional/incisional; FNA not adequate) for baseline tissue. Patients will then be randomized to one of 3 arms: Anti-PD-1 mAb plus Metformin 500mg po BID, Anti-PD-1 mAb alone, Anti-PD-1 mAb plus Rosiglitazone 4mg po qdaily. Five weeks (+/- 7 days) after initiation of therapy a patient will undergo a repeat biopsy (core or excisional/incisional; FNA not adequate) for correlative analysis. The patient will then continue on study therapy for up to 2 years, or until progression of disease or unacceptable toxicity, whichever occurs first. RECIST 1.1 with modifications, to allow for continued therapy until progressive disease is confirmed if the patient is clinically stable, will be used in the trial.

Trial Comparing Standard of Care Therapy With and Without Sequential Cytoreductive Intervention for Patients With Metastatic Foregut Adenocarcinoma and Undetectable Circulating Tumor-Deoxyribose Nucleic Acid (ctDNA) Levels

This is a randomized, open label, single-center, phase 2, randomized controlled trial of sequential cytoreductive intervention versus standard of care therapy for patients with intervenable oligometastatic (stage IV) cancer of the upper gastrointestinal (GI) tract and undetectable ctDNA at the time of randomization after a three-month induction chemotherapy period.

Mannatide Combined With CAPOX and Tislelizumab for Advanced Gastric Cancer.

This is a multicenter, open-label, single-arm phase II study evaluating the efficacy and safety of mannatide in combination with CAPOX chemotherapy and tislelizumab as first-line treatment for patients with recurrent or metastatic gastric adenocarcinoma or gastroesophageal junction adenocarcinoma. Eligible patients will receive oxaliplatin, capecitabine, tislelizumab, and oral mannatide. Tumor response will be assessed according to RECIST version 1.1. Patients without disease progression after induction treatment may continue maintenance therapy with capecitabine, tislelizumab, and mannatide. The primary objective is to evaluate objective response rate (ORR). Secondary objectives include progression-free survival (PFS), overall survival (OS), disease control rate (DCR), duration of response (DoR), and safety. Exploratory analyses will investigate immune microenvironment changes and potential predictive biomarkers using blood, tumor tissue, and stool samples.

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.
