Filter by:This study will investigate the effects of atezolizumab on select cancer types in people whose analysis of tumour DNA and RNA indicates they may be sensitive to atezolizumab. This study aims to determine if the information from the cancer genome analysis corresponds with the effects of atezolizumab on individuals and their cancer. This is a Phase 2 study, which is undertaken after preliminary safety testing on a drug is completed, and will involve approximately 200 participants. Participants are assigned to one of 8 cohorts based on their primary tumour type: breast, lung, gastrointestinal (GI), primary unknown, genitourinary (GU), sarcoma, gynecological, and 'other' cancer types. Participants in all cohorts will receive the same dose of atezolizumab (1200 mg every 3 weeks). In the first stage for each cohort, 8 participants will be enrolled and if no participants respond to treatment, enrollment to that cohort will be closed. If 1 or more participants respond to treatment, up to 16 additional participants will be enrolled to that cohort. Participants continue on treatment until they no longer may benefit from the treatment or they decide to stop treatment.
This phase II trial studies how well radiation therapy works for the treatment of gastrointestinal cancer that are spreading to other places in the body (metastatic). Radiation therapy uses high energy x-rays to kill cancer cells and shrink tumors. This trial is being done to determine if giving radiation therapy to patients who are being treated with immunotherapy and whose cancers are progressing (getting worse) can slow or stop the growth of their cancers. It may also help researchers determine if giving radiation therapy to one tumor can stimulate the immune system to attack other tumors in the body that are not targeted by the radiation therapy.
AK105 is a humanized monoclonal antibody that specially binds to PD-1. Anlotinib is a small molecule tyrosine kinase inhibitor. Based on the mechanism study, tumor vascular abnormalities promote tissue hypoxia and increase lactic acid, thereby activating immunosuppression and inhibiting T cell function. Anti-angiogenic drugs enhance the infiltration of effector immune cells by inducing normalization of blood vessels and reducing immunosuppression.
This is a phase II, open-label, prospective single-centered study. Subjects who meet the inclusion/exclusion criteria will be allocated to appropriate cohorts: 1) gastric cancer, 2) esophageal cancer and 3) hepatocellular carcinoma. Each cancer cohort group will be treated with two cycles of neoadjuvant immune checkpoint inhibitor of IMC-001 (1 cycle = 2 weeks) followed by curative resection and be followed up consecutively.
This clinical trial is evaluating a drug called BT5528 alone and in combination with nivolumab in participants with advanced solid tumors historically known for expression of EphA2. The main goals of this study are to: - Find the recommended dose(s) of BT5528 that can be given safely to participants alone and in combination with nivolumab - Learn more about the side effects of BT5528 - Learn about how effective BT5528 is for the treatment of ovarian cancer, urothelial/bladder cancer, lung cancer (NSCLC), triple-negative breast cancer, head and neck cancer (HNSCC), and gastric/upper gastrointestinal cancer. - Learn more about BT5528 therapy alone and in combination with nivolumab.
The aim of this study is to investigate the diagnostic accuracy of the C Protein Reactive (CRP) for the detection of Anastomotic leakage after surgery for digestive cancer. The standard protocol in our unit is to measure the CRP on the second and fourth postoperative day. The main aim of the study is to investigate the diagnostic accuracy of the ratio CRP on the fourth postoperative day on CRP on the second postoperative day (CRP_D4/CRP_D2). Secondary outcomes are the diagnosis accuracy of the CRP_D4 and CRP_D2.
IMPROVE-IT2 is a randomized multicenter trial comparing the outcomes of ctDNA guided post-operative surveillance and standard-of-care CT-scan surveillance. The hypothesis of this study is that ctDNA guided post-operative surveillance combining ctDNA and radiological assessments could result in earlier detection of recurrent disease and identify more patients eligible for curative treatment.
Despite improvements in a range of chemo, radio and surgical therapies, the overall survival at 5 years from gastrointestinal cancer remains poor. Endoscopic early diagnosis is a key strategy to improve survival but the detection rate of early cancer varies among different countries. Risk factor questionnaire result is easy to be obtained and may be of great help for improving the detection rate. The aim of this research is to validate a risk factor questionnaire to help predict gastrointestinal cancer therefore allowing earlier diagnosis and higher detection rate.
The primary aim of this study is to investigate potential differences in vascular function between patients receiving 5-Fluorouracil (5-FU) chemotherapy, patients receiving chemotherapies other than 5-FU, cancer survivors who were treated with 5-FU, and an age and sex matched control. 5-FU is the third most commonly administered chemotherapeutic agent and its use is associated with the second most occurrences of cardiotoxicity. Despite the known cardiotoxic effects of 5-FU, it's effects on the human vasculature are not well understood. To achieve the goals of this project Laser Doppler flowmetry (LDF) will be used to assess blood flow within the skin microcirculation of the forearm in cancer patients who have received 5-Fluoruracil within the past 30 days (Experimental Group), cancer patients receiving radiotherapy and/or chemotherapy other than 5-Fluorouracil, and an age and sex matched control (Control Group). LDF utilizes a small (~3 cm) non-invasive sensor placed on the skin. The sensor shines light into the skin, and upon contact with red blood cells (RBCs), the light is reflected and scattered. This information is used to evaluate microvascular blood flow and has previously been used in clinical populations.
The aim of our study was to demonstrate the efficacy and feasibility of the medical consortium for screening upper gastrointestinal cancers with magnetically controlled capsule gastroscopy.
