Filter by:This study will evaluate the safety, tolerability, and preliminary antitumor activity of CAN04 both as a monotherapy and in combination with standard of care treatment in subjects with solid cancer tumors. Following completion of the first part, the dose escalation cohorts, and determination of maximum tolerated dose or recommended phase 2 dose (MTD/RP2D), safety and tolerability will be further evaluated in an expanded cohort of subjects with pancreatic or lung cancer, as monotherapy or in combination with the standard of care treatment and to identify the RP2D of CAN04 in combination with standard of care. In addition, early signs of efficacy during treatment with CAN04 will be investigated.
One striking observation is that a large portion of the inter-person variation in serum 25-hydroxyvitamin D (25(OH)D) levels is unexplained. In vitro and in vivo studies indicate vitamin D synthesizing and metabolizing enzymes are Mg-dependent. Magnesium (Mg) supplementation substantially reversed the resistance to vitamin D treatment in patients with magnesium-dependent vitamin-D-resistant rickets. The investigators reported in 2013 from observational studies conducted in the general US population that Mg intake significantly interacted with vitamin D intake in affecting vitamin D status as well as interacted with serum 25(OH)D in risk of cardiovascular disease mortality and, maybe, colorectal cancer mortality. The potential interaction between Mg and vitamin D was supported by two subsequent studies, including a Finnish cohort study and a mouse study. In the parent study (Personalized Prevention of Colorectal Cancer Trial, NCT01105169), the investigators proposed to measure blood concentration of total 25(OH)D as a secondary aim using Elisa approach. However, following the novel finding of Mg-vitamin D interaction published by the investigators in 2013, they submitted a separate grant application to NCI which was funded in 2014. In the new study, the investigators proposed to use a LC-MS approach, which is more accurate and specific than an Elisa method, to measure 5 vitamin D metabolites. This new ancillary study allows the investigators to evaluate whether Mg supplementation differentially affects vitamin D synthesis and metabolism dependent on baseline serum 25(OH)D levels using existing biospecimens collected in our double-blind placebo-controlled randomized chemoprevention trial.
Colorectal cancer is a preventable and/or a treatable cancer, but at least 43% of the United States population is not up-to-date with screening. Although 90% of colorectal cancer screening is done using colonoscopy, most other countries use fecal immunochemical tests, reserving colonoscopy for those with a positive fecal immunochemical test. This project will provide the foundation for a paradigm shift for colorectal cancer screening in the United States by identifying how well 5 different FITs work for detecting screening relevant neoplasia, thus reducing morbidity and mortality for colorectal cancer.
Various antiangiogenic agents have a modest effect in prolonging overall survival in solid tumours. In colorectal cancer it is clear that there are some patients in whom bevacizumab significantly prolongs survival, but it is not effective in the majority of patients. Biomarker studies using tumour tissue and blood have failed to define a consistent biomarker that correlates with a beneficial effect of bevacizumab on survival. DCE-MRI can detect changes in tumour blood flow which, in early phase drug studies, correlated with subsequent tumour responses, but is too expensive and time consuming to be used in larger scale trials. DCE-US is a promising biomarker for use in this group of patients with antiangiogenic agents, as detailed above. The investigators wish to use this technique as a predictive biomarker for any effects Aflibercept has on OS and PFS in patients with metastatic colorectal cancer refractory to standard treatment.
This phase I/II trial studies the best dose and side effects of glutaminase inhibitor CB-839 and how well it works with panitumumab and irinotecan hydrochloride (phase I only) in treating patients with RAS wildtype colorectal cancer that has spread to other places in the body and does not respond to treatment. Glutaminase inhibitor CB-839 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as panitumumab, may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as irinotecan hydrochloride, 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. Giving glutaminase inhibitor CB-839 with panitumumab and irinotecan hydrochloride may work better in treating patients with colorectal cancer.
The purpose of this study is to confirm the safety and tolerability of TAK-931 in a cohort of Western participants with metastatic solid tumors and to evaluate the anti-tumor activity of TAK-931 in participants with metastatic pancreatic cancer, colorectal cancer (CRC), squamous esophageal cancer (sqEC), and squamous non-small-cell lung cancer (sqNSCLC).
Prospective research of circulating tumor cells as markers of progression risk in colorectal cancer.
Oxaliplatin-induced neuropathy is a major dose-limiting side effect in patients with colorectal cancer treated with the FOLFOX chemotherapy regimen. Hypersensitivity to cold is the sensory hallmark of oxaliplatin-induced neuropathy, and it can predict the development of long-term neuropathy. In this study, the investigators aim to determine whether intravenous lidocaine can prevent oxaliplatin-induced cold hypersensitivity.
This study determine the maximal tolerate dose
The aim of this study is to investigate the interaction between diet - primary meat and fiber - and polymorphisms in Toll-like receptors in relation to risk of colorectal cancer in a Danish prospective cohort.
