Gastroesophageal Cancer

The purpose of this study is to evaluate the efficacy and safety of zanidatamab for the treatment of participants with previously treated solid tumors that have Human Epidermal Growth Factor Receptor 2 (HER2) Immunohistochemistry (IHC) 3+ overexpression.

The goal of this clinical trial is to determine the MTD or OBED of DA-3501 given in Q3W to determine a wRP2D in patients with advanced CLDN18.2 expressing (CLDN18.2+) GC/GEJ and advanced CLDN18.2+ PDAC. Participants will receive the assigned dose once every three weeks and, according to the study procedures, will undergo tumor assessments as well as safety assessments, PK evaluations, and ADA testing.

This study is designed to characterize the safety, tolerability, and anti-tumor activity of MDX2001 in patients with advanced solid tumors.

The survival of patients with incurable gastroesophageal cancer can extend over a year with anticancer therapy. However, the number of patients with deteriorating quality of life in this patient group steadily decreases over time during the treatment. Potentially reversible causes related to deterioration of quality of life are diminished muscle mass, physical capacity and nutritional status. Therefore, interventions that can target these in order to maintain or improve quality of life are urgently needed. However, it is yet unknown whether improvement of physical capacity and nutritional status improves quality of life in patients with incurable gastroesophageal adenocarcinoma after failure of first-line treatment. Since these patients are in a precarious situation, the benefits and harms of a combined exercise and nutritional intervention should be carefully evaluated.Therefore this study investigates the effect of a combined exercise and nutrition intervention compared to usual care on quality of life in incurable GAC patients after progression upon first-line treatment. A total of 196 patients with metastasized gastroesophageal cancer will be recruited and randomly allocated 1:1 to standard care or standard care plus a combined exercise and nutritional intervention.

The purpose of this study is to determine how the STRONG intervention compares with usual care for reducing malnutrition among gastroesophageal cancer patients.

The HER-OIC clinical trial is a Phase 1b/2a study investigating a new combination of treatments for patients with HER2-positive gastroesophageal cancer. Standard treatment for localized gastroesophageal cancer usually involves chemotherapy before and after surgery. This study aims to see if adding targeted therapy (zanidatamab) and immunotherapy (tislelizumab) to standard chemotherapy is safe and effectively eliminates the tumor. The goal is to improve the pathological complete response (pCR) rate, which is the percentage of patients who have no visible cancer cells remaining in the tissue removed during surgery.

To compare the symptoms of patients who have a MIPG to the symptoms of patients who have a MITG.

ROSETTE trial is an open-label, randomized phase II study designed to investigate treatment strategies for patients with limited metastatic gastric or gastroesophageal adenocarcinoma. Eligible patients are randomized to receive either systemic treatment followed by surgeon-led local treatment, or systemic treatment alone. Systemic treatment combines immunotherapy with chemotherapy, with or without targeted therapy, while the surgeon-led local treatment utilizes a surgery-centric, multi-modality approach involving resection of both primary and metastatic tumors where feasible. For unresected or unresectable metastatic lesions, alternative local therapies are provided. The primary endpoint is the 1-year event-free survival (EFS) rate. Secondary endpoints include objective response rate (ORR), disease control rate (DCR), extended EFS, overall survival (OS), pathologic complete response rate (pCR), major pathologic response rate (MPR), and R0 resection rate.

The SCORE study is a prospective, multi-site clinical trial designed to collect blood and tissue samples, along with relevant clinical data, from participants diagnosed with various solid tumors. The collected specimens and information will be used to evaluate the clinical performance of Natera's molecular residual disease (MRD) testing across multiple cancer types. The study aims to assess the ability of Natera's assays to detect circulating tumor DNA (ctDNA) as a marker for disease recurrence and treatment response.

Cohort 1 \[CLOSED\] Study treatment involves two segments: (1) Induction Immunotherapy segment with pembrolizumab monotherapy every 3 weeks until irRECIST PD and (2) Combination Therapy segment. Nab-paclitaxel may be utilized in place of paclitaxel at investigator's discretion for subjects with paclitaxel reactions. Cohort 2 Patients are randomized to Arm A or B. Treatment in both arms includes pembrolizumab + RAM + paclitaxel.

This is a prospective, randomized, open-label, two-arm phase 2 trial that will evaluate whether the use of Pulsed Low-Dose-Rate radiation technique, as compared to standard radiation, is associated with reduced rates of clinically significant esophagitis during and following chemoradiation.

This is an open-label,multi-centre, phase 1b safety and feasibility study aiming to assess the safey and feasibility of bemarituzumab plus chemiotherapy (FLOT) for the peri-operative treatment of resectable gastroesophageal cancer. Following this neo-adjuvant part, patients should undergo surgery. Following surgery, patients will receive FLOT chemotherapy in combination with bemarituzumab. Imaging will be performed every 3 months for the first 2 years and thereafter every 6 months as per standard of care.

The main goal of this study is to investigate the proportion of participants with locally advanced gastric and gastroesophageal adenocarcinoma without previous treatment during the last 5 years who can tolerate all planned cycles of chemotherapy and radical surgical treatment who will be prospectively randomized into two groups to undergo one of two chemotherapy regimens, followed by surgery: 1. 8 cycles of Total Neoadjuvant ChemoTherapy (TNT) with 5-Fluorouracil (5-FU), Leucovorin, Oxaliplatin, and Docetaxel (FLOT) followed by surgery. 2. 4 cycles of Neoadjuvant FLOT chemotherapy scheme preoperatively and 4 adjuvant FLOT cycles postoperatively.

This study is a prospective, open label, multi-centre phase 2 trial which assesses the efficacy and safety of standard dosing compared to extended dosing interval of nivolumab, atezolizumab or pembrolizumab in advanced/unresectable gastric/gastroesophageal junction/oesphageal adenocarcinomas with PDL1 CPS ≥5%, hepatocellular carcinoma andnon-small cell lung cancer with PDL1 TPS≥50% with no prior treatment. The investigators hypothesize that nivolumab, pembrolizumab and atezolizumab can be used efficiently at extended dosing intervals, compared to their approved labels with comparable clinical outcome.

The aim of this prospective, controlled, randomized, multicentre, single-blind study is to compare the rate of intragastric migration of 2 types of esophageal stents with and without an anti-migration device placed for locally advanced or metastatic malignant stenosis of the gastroesophageal junction.

The goal of this clinical trial is to find better protocal for adenocarcinoma of the gastric and gastroesophageal juncion. The main question is aim to answer is: 1\. The efficacy and safety of PD-1 monoclonal antibody (Sintilimab) combined with nab-paclitaxel and S-1 in the first-line treatment of advanced gastric and gastroesophageal junction adenocarcinoma. Participants will be given PD-1 monoclonal antibody, nab-paclitaxel and tegio.

This trial is a prospective, monocentric, non-therapeutic, interventional cohort study aiming to decipher the immune TME through standard neoadjuvant CT in resectable G/GEJ adenocarcinomas. This study will also longitudinally monitor MRD during neoadjuvant and adjuvant therapy.

Surgery with or without neoadjuvant therapy is usually used as the treatment for resectable esophageal cancer or esophageal- gastric junction cancer. Patients who have a poor response to neoadjuvant therapy and have an incomplete (R1) resection or have metastatic lymph nodes in the resection specimen (N+) are especially at risk of recurrence, to continue with the chemotherapy± radiotherapy is often used in these cases. However, the overall survival is still poor. We designed a prospective randomized controlled tial to study whether immunotherapy could be used with chemotherapy after surgery to improve overall survival. The primary endpoint ofthe study is disease free survival, with secondary endpoints of overall survival, safety and toxicity, and quality of life.
