Filter by:This study is a single-arm, open-label, dose-escalating + dose-expansion clinical study, aiming to evaluate the safety and efficacy of CEA-targeted CAR-T cell preparations, and to preliminarily observe the study drug in CEA-positive advanced malignant tumors. The pharmacokinetic characteristics of CAR-T cell preparations for the treatment of patients with CEA-positive advanced malignancies were obtained and the recommended dose and infusion schedule.
This research is designed to determine if experimental treatment with AZD5863, a T cell-engaging bispecific antibody that targets Claudin 18.2 (CLDN18.2) and CD3, is safe, tolerable and has anti-cancer activity in patients with advanced solid tumors.
This project aims to collect peripheral blood samples from newly diagnosed gastric cancer patients and healthy individuals. Various techniques such as cfDNA sequencing, proteomics, and fragmentomics will be employed to analyze differences in the expression of ctDNA mutations, fragmentomics, and protein biomarkers between gastric cancer patients and healthy individuals. A new comprehensive diagnostic model will be established and its diagnostic value (sensitivity, specificity, accuracy, etc.) for gastric cancer will be validated. Specifically, the study will involve the following subjects and quantities: 700 participants from Zhejiang Cancer Hospital (350 gastric cancer patients and 350 healthy individuals), 200 participants from Sichuan Cancer Hospital (100 gastric cancer patients and 100 healthy individuals), and 200 participants from the Sixth Affiliated Hospital of Sun Yat-sen University (100 gastric cancer patients and 100 healthy individuals). Peripheral blood samples (a total of 15mL from each participant, collected in 3 tubes) will be collected from all subjects. The collected blood samples will undergo multi-omics sequencing including cfDNA methylation sequencing, proteomics, and genomics to establish a multi-omics-based early diagnostic model.
This is a prospective, one-arm, single-center phase II study. The objective was to evaluate the efficacy and safety of domestic PD-1 antibody Sintilimab combined with modified FLOT regimen in the treatment of metastatic gastric cancer. To compare the time of maintenance of treatment after induction of chemotherapy with sintilimab combined with modified FLOT regimen until the reapplication of induction regimen with or without the combination of sintilimab, and the time of secondary progression after signing informed consent until the reapplication of induction regimen with or without the combination of sintilimab.
This is a Phase II/III, randomized, multicenter, open-label clinical trial designed to evaluate safety and efficacy of RC48-ADC combine with Toripalimab and chemotherapy or RC48-ADC combine with Toripalimab and Herceptin as first-line treatment in human epidermal growth factor receptor 2 (HER2)-expression participants with locally advanced or metastatic gastric cancer.
This is a study intended to utilize endoscopic biopsies from gastric precancerous/ cancerous lesions and adjacent normal mucosa to characterize tissue biochemical composition changes as determined by mass spectrometry lipidomic/ proteomic profiling, and correlate these changes with histopathologic results, and Raman spectra as determined by SPECTRA IMDx™. The study site will be National University Hospital.
The purpose of this study is to find out whether treatment with Serplulimab combined with Trastuzumab and Chemotherapy will improve the survival of gastric cancer patients with stage II-III after surgery.
To provide preventive and therapeutic strategies for participants with gallstones after gastric cancer by comparing the risk of postoperative gallbladder stone formation with two different resection ranges using the Roux-en-Y reconstruction modality in radical gastric cancer surgery.
ECDNA is almost non-existent in normal cells, but exists in nearly half of human cancer cells, indicating that studying such abnormal DNA is of great significance for our understanding of tumor formation and evolution. The changes in ecDNA expression in intestinal type gastric cancer may be closely related to the occurrence and development of gastric cancer. Dynamic monitoring of changes in ecDNA expression in the gastric mucosa may help predict the occurrence of gastric cancer and guide subsequent treatment. By collaborating with multiple endoscopic centers to conduct gastroscopy biopsies on patients with gastric precancerous lesions, we aim to further explore the role of ecDNA in the occurrence and development of gastric cancer through continuous follow-up.
The goal of this clinical trial is to test a new PET tracer in patients with HER2-positive breast or gastric cancer. This tracer is made of radioactively labeled trastuzumab, and can show where HER2 is present in the body using a PET-scan. For this research, the investigators make PET-scans in people with HER2-positive, metastasized breast- or gastric cancer. The investigators will investigate if the new HER2-tracer correctly shows all tumor lesions. In the future, this method may be useful to help predict who will benefit from certain HER2-directed therapies. Participants will be injected with the radioactive tracer once. After injection, participants will undergo 3 PET-scans. Each PET-scan will take a maximum of 60 minutes. The PET-scans are on separate days within a week after injection of the tracer (e.g. 1 day, 2 days and 4 days after injection). Furthermore, the investigators will take 7 blood samples (5 mL each). Participants are not required to stay at the hospital. The first 3 participants will undergo an extra PET-scan 1 - 2 hours after injection. The amount of radioactivity injected will be 37 MBq (± 10%).
