This is a single center, prospective, open label phase I study evaluating the safety and tolerance of standard first-line chemotherapy XELOX regimen combined with GLS-010 (anti-PD-1 antibody) and different doses of Lenvatinib in the treatment of advanced AFP-positive gastric cancer. This study was conducted in the Department of Gastrointestinal Medical Oncology, Tianjin Medical University Cancer Institute and Hospital. In this study, patients with AFP-positive and HER-2-negative advanced gastric cancer who had not received palliative systematic treatment in the past will be enrolled. Patients who met the inclusion criteria were treated with XELOX regimen combined with GLS-010 plus Lenvatinib every 3 weeks until disease progression or intolerable adverse reactions or death. The treatment regimen is XELOX chemotherapy (oxaliplatin 130mg/ m2, d1, capecitabine 850-1250 mg/m2, bid, d1-14, every 3 weeks) in combination with GLS-010 (240 mg, intravenous infusion, every 3 weeks) plus Lenvatinib whose dose is based on the '3 + 3' dose climbing mode (12mg, 16mg and 20mg respectively, orally once a day). Safety will be evaluated by AE and laboratory tests. Patients received regular and periodic reviews, with imaging evaluations every 6 weeks.
To evaluate the efficacy and safety of Sintilimab combined with apatinib and chemotherapy as First-line or second-line Therapy in Treatment of HER-2 negative MSS Advanced or Metastatic GC or GEJ Cancer. At the same time, the correlation between tissue programmed death ligand-1(PD-L1) expression and blood circulating tumor cell(CTC) counts and the efficacy of immune combination therapy was also explored.
Upper gastrointestinal (GI) cancers are a major health problem in Canada. At the metastatic stage, options are limited (usually chemotherapy, immunotherapy, personalized therapies under research protocols). These options are not applicable to all patients and may have significant toxicities. Endoradiotherapy (ERT) using a radioisotope coupled with a localization vector specifically targeting tumor cells to deliver a localized dose of radiation therapy is a promising avenue as it can treat disseminated neoplastic disease in a specific manner sparing healthy tissue with minimal side effects. The main goal of this study is to confirm that patients with upper GI cancer would be eligible for ERT (177Lu-PSMA treatment by using 68Ga-PSMA PET/CT assessment).
This study will test the safety of a drug called SGN-PDL1V alone and with pembrolizumab in participants with solid tumors. It will also study the side effects of this drug. A side effect is anything a drug does to your body besides treating your disease. Participants will have solid tumor cancer that has spread through the body (metastatic) or cannot be removed with surgery (unresectable). This study will have four parts. Parts A and B of the study will find out how much SGN- PDL1V should be given to participants. Part C will use the dose found in Parts A and B to find out how safe SGN-PDL1V is and if it works to treat solid tumor cancers. In Part D, participants will be given SGN-PDL1V with pembrolizumab to find out how safe this combination is and if it works to treat solid tumor cancers.
To investigate the value of CTCs and ctDNA in the diagnosis of metastasis in ascites/peritoneal flushing fluid and blood; To investigate the influence of laparoscopic CO2 pneumoperitoneum establishment on peritoneal and hematogenous metastasis of advanced gastric cancer; To explore the influence of the number and type of CTCs and ctDNA on metastasis and prognosis.
To evaluate the correlation between gut microbiota and metabolites in Borrmann type IV gastric cancer; To find the effects of microflora and metabolites on target organs; To detect the mechanism of key flora and metabolite by in vitro and in vivo experiments; To construct models of gut microbiota and metabonomics by machine learning.
In this phase 2 study, we combined sintilimab, paclitaxel and S-1 as regimen to treat gastric cancer patients with peritoneal metastasis. We are aim to estimate the efficacy and safety of this regimen in the phase 2 study.
Gastric cancer is the fourth leading cause of cancer-related death worldwide. Accurate assessment of the clinical responses to current treatment regimens is key to improving the prognosis and prolonging the survival of patients. In this study, two hundred and fifty patients with gastric cancer who ought to receive neoadjuvant therapy, conversion therapy or palliative chemotherapy will be enrolled, and patient-derived organoids from their tumor biopsies will be used to test the sensitivity of chemotherapy drugs which mainly include 5-fluorouracil, irinotecan, oxaliplatin and paclitaxel.
This trial is an investigator-initiated, single-center, open-label, single-arm exploratory study of mRNA neoantigen tumor vaccine in the treatment of advanced gastric cancer, esophageal cancer, and liver cancer, including two phases: dose escalation and dose expansion. To evaluate the safety and tolerability of neoantigen tumor vaccine in subjects with advanced gastric cancer, esophageal cancer and liver cancer by conducting dose escalation trial in subjects diagnosed with advanced gastric cancer, esophageal cancer and liver cancer, and preliminarily evaluate the efficacy of neoantigen tumor vaccine in subjects with advanced gastric cancer, esophageal cancer and liver cancer. According to the characteristics of safety and efficacy data in the dose escalation phase, the dose expansion is performed at the intended clinical dose based on the investigator's judgment, and the treatment is performed in combination with PD-1/L1 to further evaluate the efficacy and safety profile of neoantigen tumor vaccine at a specific dose. Both the dose escalation phase and dose expansion phase include a screening period (Week -4 ~ Week -2), a baseline period (Week -1 ~ Day -1), a treatment period (Day 1 ~ Week 8 or 16), and a follow-up period. Subjects who signed and provided the formal informed consent entered the screening period. The treatment period included the initial treatment period (Day 1 ~ Week 8) and the enhanced treatment period (Week 12 ~ Week 16). The investigator determined whether to enter the enhanced treatment period based on the comprehensive judgment of the subject's efficacy, safety, compliance and other factors from Week 8 to Week 12. The dose escalation phase follows standard 3+3 design. 12-18 subjects are expected to be enrolled at 3 given dose level. The investigator will choose the optimal clinical dose for dose expansion, which can be one dose group or multiple dose groups. PD-1/L1 drugs are used in parallel to further confirm the efficacy and safety of neoantigen tumor vaccine, with about 18 subjects. The usage and dosage of PD-1/L1 should aligned with the package insert.
