Active clinical trials for "Stomach Neoplasms"

Study Design: This is a Phase II study to assess the safety and clinical efficacy of this combined chemotherapy-free regimen (zanidatamab and tislelizumab) in HER2-positive advanced gastric/gastroesophageal junction (GEJ) adenocarcinoma after first line treatment. The study will be conducted as phase II study to evaluate the safety and tolerability of the combination treatment of zanidatamab and tislelizumab and determine anti-tumor activity in HER2-positive advanced gastric/GEJ adenocarcinoma patients. This study will be conducted at up to 6 medical centers in Korea. Patients who are HER2-positive will be confirmed by immunohistochemistry (IHC) or fluorescent in situ hybridization (FISH)/silver in situ hybridization (SISH) at local laboratory. Patients who meet all eligibility criteria will be enrolled to this study and receive treatment with zanidatamab and tislelizumab until progressive disease is confirmed or at least 1 discontinuation criterion is met. Study Assessments: Patients will be monitored for safety, tolerability, and antitumor activity throughout the study. Safety will be assessed throughout the study by monitoring AEs/SAEs, and laboratory results. Vital signs, physical examinations, Eastern Cooperative Oncology Group (ECOG) performance status change, ECG results, echocardiogram/MUGA, and other examinations will also be used for safety assessment. Anticancer activity will be evaluated by the investigator using RECIST 1.1. Radiological assessment of tumor response status will be performed every 6 weeks (±7 days) from (anchored to) Cycle 1 Day 1 for the first 54 weeks and every 12 weeks (±7 days) thereafter until disease progression, withdrawal of consent, death, or start of a new anticancer therapy. Patients who discontinue study treatment early for reasons other than disease progression will continue to undergo tumor assessments following the original plan until the patient begins a subsequent anticancer treatment, experiences disease progression, withdraws consent, is lost to follow up, death, or until the study terminates, whichever occurs first. Duration of Patient Participation: Screening Period is within 28 days prior to the first dose of study drug. Treatment Period starts with the first dose administration of study drug and ends when the patient is discontinued for study treatment when they are no longer considered to be achieving clinical benefit due to confirmed disease progression or unacceptable toxicity, or due to death or withdrawal of consent. Safety Follow-up. Patients who discontinue treatment for any reason will be asked to return to the clinic for the Safety Follow up Visit (to occur approximately 30 days (±7 days] after the last dose of study drug(s) or before the initiation of a new anticancer treatment, whichever occurs first). In addition, telephone contacts with patients treated with zanidatamab and tislelizumab should be conducted to assess immune-mediated AEs and concomitant medications (if applicable, i.e. associated with an immune-mediated AE or is a new anticancer therapy) at 60 (±14 days) and 90 days (±14 days) after the last dose of study drug(s) regardless of whether the patient starts a new anticancer therapy. Survival Follow-up. Patients will be followed for survival and further anticancer therapy information after discontinuation of study treatment via telephone calls, patient medical records, and/or clinic visits approximately every 3 months (±14 days) after the Safety Follow-up Visit or as directed by the investigator until death, loss to follow-up, withdrawal of consent, or study completion.

To explore the safety and clinical efficacy of cisplatin combined with RC48 and anti-PD-1 antibodies AK105 in Her-2 positive advanced gastric cancer.

The project is primarily aimed at identifying and subsequently validating the predictive role of plasma concentrations of VEGF-A (vascular endothelial growth factor A), VEGF-D (vascular endothelial growth factor D) and s-VEGFR2 (soluble Vascular Endothelial Growth Factor Receptor 2) measured prior to initiation and during second-line treatment with paclitaxel and ramucirumab in patients with unresectable gastric cancer pretreated with first-line chemotherapy. For the primary endpoint, the efficacy parameter chosen is PFS, calculated from day 1 of treatment to date of progression or death.

Investigators assessed the effectiveness of HLX10, Trastuzumab and Chemotherapy in First-line Treatment of HER2-positive Recurrent/Metastatic Gastric Cancer

It is very significant that assessing staging in gastric cancer patients before surgery, furthermore, determining the optimize surgical strategy ,predict the the efficacy of neoadjuvant therapy for patients. For patients who are ineffective in neoadjuvant therapy, surgery will be more meaningful. It has been reported that the application of CT(computed tomography,CT) and MR(magnetic resonance,MR) in staging of gastric cancer, but not in predicting clinical response to neoadjuvant therapy for gastric cancer. Only a few studies focused on T staging using conventional MRI in gastric cancer, however , relatively new sequences in the chest deserve widely used. To develop a pre-treatment evaluation methods for TN staging in patient with gastric cancer by utilization of the new imaging methods (T2-TSE-BLADE,T2 maps, StarVIBE, iShim-DWI and high resolution CT). By analysing the relationship between TN staging and imaging features to find the imaging characteristics for TN staging, and to find the indicators of new technology and reference values for facilitate pre-treatment diagnosis of TN staging, optimize surgical strategy , predict the the efficacy of adjunctive therapy , and OS and define the range of lymph node for radiotherapy , as making personal treatment planning for gastric cancer .

This phase II MATCH trial studies how well treatment that is directed by genetic testing works in patients with solid tumors or lymphomas that have progressed following at least one line of standard treatment or for which no agreed upon treatment approach exists. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic abnormalities (such as mutations, amplifications, or translocations) may benefit more from treatment which targets their tumor's particular genetic abnormality. Identifying these genetic abnormalities first may help doctors plan better treatment for patients with solid tumors, lymphomas, or multiple myeloma.

Background: - Recent advances in cancer research have led to new therapies to treat the disease. It is important to continue these advances and discover new ones. To do that, researchers need tissue samples from solid tumors. This study will collect such samples from people already scheduled to have a procedure at the National Institutes of Health Clinical Center (NIHCC). Objectives: - To collect tissue samples for use in studying new ways to treat tumors. Eligibility: Adults 18 years and older, with a precancerous or cancerous solid tumor who are scheduled to have surgery or a biopsy at the NIHCC. Children under the age of 18 but who are older than 2 years of age are eligible to be enrolled on the research sample collection portion of this study if they will have a biopsy or surgery as part of their medical care. Design: Before their procedure, participants will have a small blood sample taken. Some participants will undergo leukapheresis. In this procedure, blood is removed through a tube in one arm and circulated through a machine that removes white blood cells. The blood, minus the white blood cells, is returned through a tube in the other arm. The procedure takes 3-4 hours. For all participants, during the surgery or biopsy, pieces of the tumor and pieces of normal tissue near it will be removed for this study. The rest of the tumor or precancerous growth will be sent to a lab for analysis. Participants will return to the clinic about 6 weeks after the operation for a routine checkup. Some may have to return for additional follow-up.

International registry for cancer patients evaluating the feasibility and clinical utility of an Artificial Intelligence-based precision oncology clinical trial matching tool, powered by a virtual tumor boards (VTB) program, and its clinical impact on pts with advanced cancer to facilitate clinical trial enrollment (CTE), as well as the financial impact, and potential outcomes of the intervention.

To observe and evaluate the efficacy and safety of oxaliplatin with oapecitabine（XELOX）combined with apatinib as post-operative chemotherapy in locally advanced gastric adenocarcinoma with D2 dissection

This is a randomized, open-label study done in 3 hospitals in China. Patients with stage IIIB and IIIC gastric cancer who undergo curative D2 gastrostomy will be randomly assigned after surgery to receive adjuvant chemotherapy with oxaliplatin and capecitabine, or adjuvant chemotherapy combined Traditional Chinese treatment. The primary outcome was disease-free survival and 3-year disease-free survival rate in the intention-to-treat population.
