Active clinical trials for "Stomach Neoplasms"

The purpose of this study is to observe and preliminary explore the efficacy and safety of combination of Apatinib and SHR-1210 regimen in treating advanced hepatocellular carcinoma or gastric cancer. Apatinib is a small-molecule vascular endothelial growth factors receptor (VEGFR) tyrosine kinase inhibitor, similar to vatalanib (PTK787), but with a binding affinity 10 times that of vatalanib or sorafenib. SHR-1210 is a humanized anti-PD-1 monoclonal antibody.

phase II study of weekly metronomic chemotherapy using weekly Paclitaxel, Oxaliplatin, Leucovorin and 5-FU (POLF) in patients with advanced gastric cancer

Linus Pauling and Dr Ewan Cameron have published two retrospective studies about using high dose vitamin C to treat cancer patients forty years ago. Their studies have shown that high dose vitamin C usage could significantly prolong overall survival of patients with advanced cancer. Recently, preclinical study has shown that human colorectal cancer cells harboring KRAS or BRAF mutations are selectively killed by high levels of ascorbic acid (AA). High dose of AA impairs tumor growth in Apc/KRASG12D mutant mice. Previous phaseⅠclinical trials have found that high dose (1.5g/kg or 90g/m2) iv AA is well tolerated in cancer patients. This protocol is a phase Ⅲ, study of ascorbic acid (AA) infusions combined with treatment with mFOLOX6 versus mFOLOX6 alone as first-line therapy in patients with recurrent or advanced gastric cancer.

This multicenter, randomized, double-blind study will evaluate the efficacy and safety of apatinib combined with paclitaxol versus placebo combined with paclitaxol in advanced gastric cancer or gastroesophageal junction carcinoma patients with peritoneal metastasis. Patients will be randomized to one treatment arm: Arm A: apatinib 500mg qd, Paclitaxol 80mg/m2, d1, d8, d15,every 4 weeks ; Arm B: placebo 500mg qd, Paclitaxol 80mg/m2, d1, d8, d15,every 4 weeks ; Tumor assessment will be done every 8 weeks according to RECIST 1.1. The primary endpoint is progression free survival (PFS).

The prognosis of metastatic gastric cancer is poor. Chemotherapy occasionally converts an initially unresectable gastric cancer to a resectable cancer. Previous studies showed patients with unresectable gastric cancer may obtain a survival benefit from chemotherapy and subsequent curative surgery. The key of conversion therapy of initially unresectable metastatic GC is the high response rate. Apatinib, a novel targeted inhibitor of VEGF receptor 2 (VEGFR2), shows significant antitumor activity in the patients with GC. The purpose of this study is to investigate the efficacy and safety of S1/Paclitaxel chemotherapy plus Apatinib in the conversion therapys of metastatic gastric cancer.

Gastric cancer is the leading cause of cancer death in China. Most patients are unresectable or metastatic disease at the time of diagnosis. Systemic therapy was required for the patients with advanced stage. Platinum combined with fluoropyrimidines always were considered as first line treatment. After failure of initial therapy, single agent of taxanes was used as second line treatment. However, there is no relative standard chemotherapeutic regimen in the third therapy except oral anti-angiogenesis drug-Apatinib. So this study was designed to explore the role of single agent with irinotecan as third line treatment in patients with metastatic gastric cancer in China.

The purpose of the study is to evaluate the safety and efficacy of laparoscopic distal D2 gastrectomy (LDG) compared with open surgery (ODG) for resectable gastric cancer, to determine whether LDG can be a test arm for a future Phase III trial to evaluate the non-inferiority of overall survival compared with ODG in patients who receive neoadjuvant chemotherapy.

The purpose of this study is to assess efficacy and safety of docetaxel alone, docetaxel plus cisplatin, and docetaxel plus S-1 in patients with metastatic gastric cancer after failing 1st line chemotherapy with cisplatin plus S-1 or capecitabine

The purpose of this study is to evaluate the effectiveness and safety of s-1 plus cisplatin versus 5-FU plus cisplatin as first-line therapy in the treatment of patients with advanced gastric cancer.

Although there has been some progress in chemotherapy for metastatic gastric cancer, no standard regimen of adjuvant chemotherapy is available, and many clinical trials have produced contradictory results. The majority of randomized clinical trials studying adjuvant chemotherapy in gastric cancer have been underpowered, involved low-volume centers, or used ineffective chemotherapy regimens. As a result, well-designed multicenter trials are still needed. The ACTS-GC trial, which demonstrated the efficacy of S-1 for stage II-III gastric cancer patients who underwent curative resection with extended lymph-node dissection (D2), may be valid in countries where D2 surgery is considered the standard of care. S-1 improved the 3-year overall survival from 70.1% for surgery alone to 80.1%. However, 3-year overall survival in stage IIIA and stage IIIB patients receiving S-1 were 77.4% and 63.4%, respectively, which are less satisfactory compared to the rate for stage II (90.7%). Based on the unsatisfactory outcome among later stage patients in the ACTS-GC adjuvant trial, further investigation is needed for more effective postoperative treatment of patients with stage IIIB and IV (M0) cancer. Therefore, the researchers investigated the efficacy and safety of S-1 versus S-1 plus cisplatin as adjuvant chemotherapy in patient with curatively resected gastric adenocarcinoma.
