Filter by:The purpose of this early proof-of-concept study to evaluate the safety and immunologic efficacy of AST-301 in gastric cancer patients with HER2 expression (including both HER2 low expression and overexpression) who have completed the standard adjuvant treatment (including those who discontinued the standard adjuvant treatment due to intolerance). Participants will be randomized 1:1 to either Arm 1 (Q3W, 3 cycles), or Arm 2 (Q3W, 6 cycles) of the study. Safety Monitoring Committee (SMC) will oversee safety of study at 25% (6 participants), 50% (12 participants), and 75% (18 participants) of participants receive at least 1 dose of AST-301 and survival follow up will be performed to determine disease-free survival (DFS).
To evaluate the efficacy and safety of Serplulimab in Combination With Docetaxel +S-1 vs. Docetaxel +S-1 as Adjuvant Treatment Therapy in Stage IIIc Gastric Cancer (PD-L1 + / MSI-H / EBV +/dMMR) . Secondary study objective: To observe and evaluate the overall survival and adverse events of Serplulimab in Combination With Docetaxel +S-1 vs. Docetaxel +S-1 as Adjuvant Treatment Therapy in Stage IIIc Gastric Cancer (PD-L1+ / MSI-H / EBV +/dMMR). To evaluate the safety of Serplulimab in Combination With Docetaxel +S-1 vs. Docetaxel +S-1 as Adjuvant Treatment Therapy in Stage IIIc Gastric Cancer (PD-L1 + / MSI-H / EBV +/dMMR). To explore the incidence of PD-L1 + / MSI-H / EBV + /dMMR in stage IIIc gastric cancer. To explore the correlation of PD-L1 + / MSI-H / EBV + /dMMR in stage IIIc gastric cancer.
Trastuzumab for injection is a biosimilar of Herceptin ® produced by Chia Tai Tianqing Biotechnology Co., LTD, which is a humanized IgG1 monoclonal antibody produced by chinese hamster ovary (CHO) cells. A randomized, double-blind, single-dose, parallel phase I study comparing trastuzumab for injection with Herceptin ® in healthy male volunteers was conducted to evaluate the similarities in pharmacokinetics, tolerability, safety and immunogenicity of Trastuzumab for injection and Herceptin®.
In resectable gastric cancer participants who received curative surgery, to early and more accurately detect peritoneal carcinomatosis or occult metastasis is important. Also, investigators will look at CTC numbers in different timings after operation, to investigate the possibility of early detection for peritoneal carcinomatosis or occult metastasis. Also, this study will correlate the relationship of CTC and participants' survival.
To explore the efficacy of Tislelizumab combined with chemotherapy in the treatment of advanced gastric cancer after first-line resistance
CKD-702 is a tetravalent bispecific IgG1 targeting hepatocyte growth factor receptor (MET) and epidermal growth factor receptor (EGFR). The investigators will test a hypothesis that CKD-702 may augment the efficacy of biweekly irinotecan as a 3L or later therapy for gastric cancer overexpressing either MET or EGFR.
European clinical guidelines do not establish a clear recommendation neither for nor against omentectomy of this segment, the American clinical guidelines recommend omentectomy in view of its potential long-term oncological benefit, and Japanese clinical guidelines only recommend 2nd segment omentectomy in locally advanced gastric cancers (stage T3-T4) recommending omental preservation in early gastric cancers (stage T1-T2). Faced with this lack of consensus, we propose a randomized, prospective and multicentric study in patients with resectable gastric cancer in stage T3-4 N+/- M0. Patients will be randomized into two groups, one where omentectomy of the 2nd omental portion will be performed and another where omental preservation will be performed. The aim of our study is to analyze the disease-free interval and survival between both groups, also comparing postoperative complications and mortality.
To evaluate the pathological complete response rate (pCR) of nivolumab combined with SOX (oxaliplatin + S-1) for neoadjuvant therapy of resectable gastric and gastroesophageal junction adenocarcinoma;
To evaluate the safety of robot-assisted radical gastrectomy with D2 lymph node dissection in postoperative complications in patients with neoadjuvant chemotherapy for gastric cancer (cT3-4a, N+, M0).
The aim of this single-arm prospective, multicenter, cross-sectional study is to evaluate the nutritional status and body composition on tumor regression grade with bioelectrical impedance analysis in gastric cancer patients undergoing multimodal treatment. Results of this study will reveal whether nutritional status and body composition assessment based on bioelectrical impedance analysis will become a validated and objective tool to support clinical decisions in gastric cancer patients undergoing multimodal treatment.
