Filter by:This is a multicenter, randomized, open-label, phase 2 clinical study aiming to evaluate the feasibility and efficacy of sintilimab (PD-1 inhibitor) in combination of fruquintinib and chemotherapy (S-1 plus nab-paclitaxel) versus sintilimab and chemotherapy as conversion therapy in patients with stage IV gastric cancer in China.
This study is a prospective, open label, multi-centre phase 2 trial which assesses the efficacy and safety of standard dosing compared to extended dosing interval of nivolumab, atezolizumab or pembrolizumab in advanced/unresectable gastric/gastroesophageal junction/oesphageal adenocarcinomas with PDL1 CPS ≥5%, hepatocellular carcinoma andnon-small cell lung cancer with PDL1 TPS≥50% with no prior treatment. The investigators hypothesize that nivolumab, pembrolizumab and atezolizumab can be used efficiently at extended dosing intervals, compared to their approved labels with comparable clinical outcome.
This is an open-label, Phase 1/2 study to determine the safety, tolerability, and efficacy of APL-5125 for the treatment of selected locally advanced or metastatic solid tumors with particular focus on Colorectal carcinoma (CRC).
The goal of this open-label randomized, multicenter, comparative phase II trial is to evaluate the efficacy of the immunotherapy, dostarlimab, as first-line treatment for deficient mismatch repair (dMMR)/microsatellite instability (MSI) non-resectable metastatic or locally advanced non-colorectal and non-endometrial cancers compared to the standard of care chemotherapy. Adult patients (aged ≥18 years) with histologically confirmed dMMR/MSI duodenum and small bowel adenocarcinoma, gastric and oeso-gastric junction (OGJ) adenocarcinoma with combined positive score (CPS)<5, pancreatic adenocarcinoma, ampulla of vater adenocarcinoma, adrenocortical carcinoma, carcinoma of unknown primary site, neuroendocrine carcinoma (Grade3) all primary, and soft tissue sarcoma (except Gastro-Intestinal Stromal Tumor) will be included in this study. They will be randomized and treated with either dostarlimab (experimental arm A), or chemotherapy (control arm B). Patients with documented disease progression following the first line chemotherapy (Arm B) may be eligible for crossover to be treated with dostarlimab, with the same schedule as arm A.
The goal of this study is to evaluate the safety, tolerability, pharmacokinetics (PK), immunogenicity, and anti-tumor activities of cadonilimab in combination with Ivonescimab plus chemotherapy as first-line therapy in adult subjects with HER2 negative、advanced or metastatic gastric (G) or gastroesophageal junction (GEJ) cancer.
Cadonilimab combined with paclitaxel (albumin-bound) treat advanced gastric adenocarcinoma or esophagogastric junction adenocarcinoma with PD-(L)1 inhibitors resistance
This phase I trial tests the safety, side effects studies chemotherapy followed by chemotherapy at the same time as radiation therapy (chemoradiation) before surgery (neoadjuvant) in treating patients with stage gastric (stomach) or gastroesophageal junction cancer . Chemotherapy drugs, such as docetaxel, oxaliplatin , leucovorin, fluorouracil, and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving chemotherapy and chemoradiation before surgery may make the tumor smaller and may reduce the amount of normal tissue that needs to be removed.
Gastric cancer is the fifth most common malignancy in the world after cancers of the lung, breast, colorectum, and prostate. Gastric cancer is the third leading cause of cancer death and is responsible for 723,000 deaths yearly. Gastric carcinoma (GC) is a multifactorial disease which is difficult to diagnose in early-stage because of a time lag between the onset of growth and the appearance of clinical presentation. So, its prognosis is poor as evidenced by the 5-year survival rate. Klotho is anti-aging gene encoding a protein with multiple pleiotropic effect. Cancer and ageing share comparable principles. Klotho gene has been described as a tumor suppressor gene in numerous solid tumors and hematological malignancies. Klotho expression has been shown to be significantly down-regulated in malignant tissue compared to adjacent non-malignant tissue with good prognosis in cancers with high Klotho expression, including colorectal, pancreatic, gastric, esophageal, breast, hepatocellular, ovarian, and renal carcinomas. In contrast, a recent study documented that Klotho negative invasive duct carcinoma group exhibited good prognosis than the Klotho positive group regarding the disease- free survival after the surgical resection in breast cancer patient. Lipoprotein receptor- related protein 6 (LRP6) is a type I single transmembrane protein which is a member of the low-density lipoprotein receptor (LDLR) gene family of receptors that is highly conserved among species. In 2000, LRP6 was identified as a co-receptor for Wnt and Frizzled (FZD) to transduce Wnt/β-catenin signaling. Dysregulation of LRP6 is involved in cancer. LRP6 is highly expressed in several cancer cell lines and overexpression of LRP6 promotes cancer cell proliferation. LRP6 expression is frequently upregulated in breast cancer tissue, and respective overexpression or knockdown of LRP6 induces or inhibits breast tumorigenesis. LRP6 is highly expressed in tumors of liver cancer patients, and overexpression of LRP6 promotes liver cancer cell proliferation and tumor growth. In prostate cancer, high expression levels of LRP6 are detected which activate Wnt/β-catenin signaling and glycolysis through Akt signaling. The end result is increased prostate cancer cell proliferation. The mechanism of Klotho-mediated Wnt inhibition was as a result of Klotho binding to Wnt ligands, namely Wnt3A and Wnt5A; thereby impeding binding of these ligands to their cell surface receptor.
In this study, the investigators aimed to identify independent prognostic factors for early postoperative complications and survival in elderly patients (aged ≥65 years) with gastric cancer.
This phase I finds out the possible benefits and/or side effects of using magnetic tracer FerroTrace and the fluorescent dye indocyanine green to identify the lymph nodes that cancer is most likely to have spread to in patients with gastric cancer that are undergoing gastrectomy. Using FerroTrace in combination with the indocyanine green dye may help researchers better detect the disease.
