Filter by:Fruquintinib is an oral tyrosine kinase inhibitor (TKI), which improves progression-free survival (PFS) and overall survival (OS) in patients with refractory metastatic colorectal cancer (mCRC). Here, we explore the real-world treatment patterns of fruquintinib in the third- or late-line setting for mCRC in six centers in China.
This is an observational study in which data already collected from patients with metastatic colorectal cancer will be studied. Metastatic colorectal cancer (mCRC) is a cancer of the colon (large bowel) or the rectum (lowest part of the bowel just before the anus) that has spread to other parts of the body. The study drug, regorafenib, is already approved for cancer doctors to prescribe to patients with mCRC. It is an anti-cancer drug that blocks several proteins, called enzymes, which are involved in the growth of cancer. The participants in this study were treated with regorafenib as part of their regular care from their doctors. Some studies have shown that patients with mCRC who took regorafenib had improved survival outcomes, and some of them did well on the treatment for a long time. Cancer doctors have also reported from their routine practice that some patients with mCRC are able to respond to regorafenib for a longer period than others. However, there is limited knowledge about which people this is likely to happen for. To better understand the long-term response of regorafenib treatment, there is a need for a large-scale study in the real world. The main purpose of this study is to learn more about patients who showed a long-term response to regorafenib as a mono treatment for mCRC. To do this, researchers will collect the following information from the participants' health records: Duration of treatment with regorafenib Percentage of participants who received treatment with regorafenib for at least 5 months and 4 months. Characteristics, including age, sex, race, health condition, and signs and symptoms of mCRC, of participants who received treatment with regorafenib for at least 5 months and 4 months. The data will come from an electronic health records database called the Flatiron Health Data Repository for patients in the United States. The data will be from patients with mCRC who started treatment with regorafenib between July 2013 and December 2022. Researchers will consider the data of the participants collected until May 2023. In this study, only available data from routine care are collected. No visits or tests are required as part of this study.
Colorectal cancer represents a major public health problem in France because of its high incidence and severe prognosis. Early stages of the disease are well know and have justified the establishment of a mass screening strategy. Unfortunately, the factors determining the progression to metastatic disease about them much harder to grasp. Various prognostic factors and predictors of treatment response have been identified and are being used but most of them are In practice, they are sometimes coarse and relatively little discriminant for patients. It is now possible to directly quantify the amount of circulating tumor cells in peripheral blood. Quantification of circulating tumor cells beyond a threshold of 3 cells/7,5 ml has been established as a major prognostic factor, and the rapid decrease in the number of these cells under treatment is also a predictor of response for patients suffering from metastatic colorectal cancer . Furthermore, it has also been shown that the quality and importance of the systemic and peritumoral inflammatory response in carcinomas, including colorectal, played a key role in the prognosis of patients. In particular, the presence of high levels of blood neutrophils has been raised by many studies as being followed by a poorer prognosis. However, the correlation between the presence of circulating tumor cells and high levels of neutrophils has never been studied. There is a rational to assume that this association exists, and secondly that the presence of circulating tumor cells in a proinflammatory environment represented by a high levels of blood neutrophils promotes metastasis by exerting a negative synergistic effect on the prognosis of patients. The main objective of this pilot study is to find a correlation between the amount of circulating neutrophils and the presence of circulating tumor cells in patients with colon cancer metastatic unresectable non-pretreated. The secondary objective is to investigate whether this association results in a negative synergistic effect in terms of progression-free survival and survival to one year. This is a non-interventional study. The investigators expect the inclusion in one year of thirty patients in two centers (University Hospital Centre Antoine Lacassagne Nice) to achieve these goals.
This is an observational study in which data from patients with metastatic colorectal cancer in three European countries who received STIVARGA® (regorafenib), are collected. In observational studies, only observations are made without specified advice or interventions. Metastatic colorectal cancer (mCRC) is a cancer that starts in the large bowel or the rectum (the lowest part of the gut) and has spread to other parts of the body. Regorafenib is an anti-cancer drug that blocks several proteins called enzymes, which are involved in the development and growth of cancer. A wide range of such enzymes called tyrosine kinases are targeted. In 2013, regorafenib was approved in Europe for doctors to prescribe to people with mCRC who have previously been treated or cannot receive other available treatments. It is known that doctors may change/reduce the amount (the dose) of regorafenib they give (flexible dosing), so that the patients better tolerate the treatment. However, little information is available on the doses of regorafenib given in France, Italy, and Belgium in usual practice. In this study researchers want to learn more about how and in which amount regorafenib is usually given to patients with mCRC in France, Italy, and Belgium: - at the beginning - during, and - at the end of the regorafenib therapy. In addition, the study team will collect data about/if: - the treatment duration at each treatment dose of regorafenib, - the number of people who received reduced initial dosing of regorafenib in real word settings in France, Italy, and Belgium, - reduced (flexible) initial dosing of regorafenib allows patients to stay longer on treatment. To answer these questions, the researchers will look back at cases that have already happened when the study begins. The data will be collected through an online case report form. The doctors will provide case histories of mCRC patients who started regorafenib treatment in most recent 3 years and 4 months (from January 1, 2019 to Apr 30, 2022) or up until 3 months prior to the date of data collection. Besides this data collection, no further tests or examinations are planned in this study. There are no required visits or tests in this study.
Fruquintinib DDI Study with P-gp and BCRP Substrates
This is a prospective randomized phase II trial was done in clinical oncology department at Kasr Alainy hospital, Cairo university (NEMROCK) to evaluate the role of intensification of chemotherapy in the first line for treatment of metastatic colorectal carcinoma by adding third agent to standard doublet regimen on oncological outcomes & assess tolerance to the intensified treatment
Primary Objective: -Evaluate the resection rate (R0/R1) in current practice for aflibercept in combination with irinotecan plus 5-fluorouracil (FOLFIRI) in patients treated for metastatic colorectal cancer (mCRC) after failure of an oxaliplatin-containing regimen Secondary Objectives: - Evaluate overall survival, progression-free survival and relapse-free survival. - Evaluate conversion rates (initially unresectable disease which became resectable after chemotherapy, with R0/R1 resection). - Evaluate histological and radiological response rates. - Evaluate rate of postoperative complications. - Evaluate safety.
The purpose of this study is to identify patients who may be eligible to participate in a separate Phase 2/3 treatment study evaluating an individualized neoantigen vaccine GRANITE for first line (1L) maintenance treatment of metastatic, microsatellite-sable colorectal cancer (MSS-CRC) sponsored by Gritstone bio. This may include the manufacturing of an individualized vaccine, which involves neoantigen prediction and generating a vaccine targeting neoantigens.
