Filter by:This randomized phase II trial studies how giving a drug called levocetirizine to patients with colorectal cancer affects their tumor response to capecitabine and bevacizumab. Capecitabine is a chemotherapy drug that blocks tumor growth by disrupting DNA and RNA synthesis and repair (cell division and survival). Bevacizumab is a monoclonal antibody that blocks the ability of tumors to grow and spread by inhibiting the growth of blood vessels that feed them. Patients with colorectal cancer can develop a resistance to the effects of bevacizumab. Levocetirizine may decrease tumor resistance to bevacizumab. Giving bevacizumab, capecitabine, and levocetirizine dihydrochloride together may be an effective treatment for refractory colorectal cancer.
This study is a randomized, multi-center study that will compare the efficacy and safety of selective internal radiation therapy (SIRT) using SIR-Spheres microspheres plus a standard chemotherapy regimen of FOLFOX6m versus FOLFOX6m alone as first-line therapy in patients with non-resectable liver metastases from primary colorectal carcinoma. Treatment with the biologic agent bevacizumab, if part of the standard of care at participating institutions, is allowed within this study at the discretion of the Investigator.
Mesenchymal stem cells (MSCs) are present in the circulation of cancer patients, and are recruited to the stroma of both the primary tumor and metastasis. Recent preclinical research has shown that in response to platinum-based chemotherapy, MSCs secrete two specific platinum-induced fatty acids (PIFAs) which induce resistance to a broad spectrum of chemotherapies. The secreted PIFAs are the fatty acid oxo-heptadecatetraenoic acid (KHT) and the omega-3 fatty acid hexadecatetraenoic acid (16:4). These PIFAs are produced via the COX-1 pathway. COX inhibitors, including indomethacin. This phase 1 study explores the safety of combining indomethacin with platinum containing chemotherapy.
This study will assess the safety and efficacy of LGX818 when combined with cetuximab or combined with cetuximab and BYL719 in patients with BRAF mutant metastatic colorectal cancer
The purpose of this study is to evaluate if giving bevacizumab prior to chemotherapy compared to giving bevacizumab at the same time as chemotherapy improves patient overall response to treatment.
The aim of this multicenter randomized phase II trial is to determine the efficacy of sorafenib and irinotecan combination versus irinotecan monotherapy or versus sorafenib monotherapy in metastatic colorectal cancer patients with KRAS mutated tumors after failure of all active drugs known to be effective.
This multicenter observational study will evaluate the efficacy and safety of first-line bevacizumab (Avastin) in combination with fluoropyrimidine-based chemotherapy in participants with metastatic colorectal cancer (mCRC). Participants for whom the treating physician has decided to initiate first-line fluoropyrimidine based chemotherapy in combination with bevacizumab will be observed for approximately 4 years.
Colorectal cancer (CRC) is the 2nd leading cause of cancer death in the US, though CRC death can be reduced by screening. However, there is uncertainty as to which screening strategy is most clinically and cost-effective from a population perspective where the aim is to optimize completion of the entire screening process continuum. Modeling studies suggest benefits and harms of colonoscopy and stool blood test strategies are similar, but generally assume 100% participation and subsequent clinically appropriate follow up--something never achieved in clinical practice. Comparative effectiveness studies of testing strategies, including comparisons of specific tests and approaches to optimizing effective test use, are necessary. Safety-net health systems care for populations at increased risk for adverse CRC outcomes, such as the uninsured and minorities, and have more limited resources. Therefore, safety-nets must resolve the uncertainty regarding the most effective screening strategy. The investigators will conduct a system-level, randomized comparative effectiveness trial of the benefits, harms, and costs of 3 screening strategies over 3 years, among 6000 patients age 50-64 years, who are not up-to-date with CRC screening, served by a large safety net health system. The three strategies studied will be: 1) Fecal immunochemical testing, with annual mailed invitation outreach (including a test kit), and a centralized process to promote participation and complete clinical follow up (FIT); 2) Colonoscopy, with annual mailed invitation outreach, and a centralized process to promote participation and complete clinical follow up (Colo); 3) Usual Care, with no mailed invitation outreach, and screening offered at primary care visits. The primary measure of benefit will be an outcome measure that summarizes patient-specific effective screening successes. The primary measure of harm will be screening non-participation. The primary measure of cost will be cost per-patient effectively screened. Our specific aims are to: 1) Compare benefits, harms, and costs of a FIT strategy versus a Colo strategy for CRC screening among patients not up-to-date with screening, and 2) Compare benefits, harms, and costs of a) the FIT strategy vs. Usual Care and b) the Colo strategy vs. Usual Care for CRC screening.
Over the last decades different life style factors have been established as risk factors for various diseases. The obesity pandemic displays a good example of a disease where great effort is undertaken to characterize risk factors associated with obesity (1). Smoking is another life style risk factor established since several decades, and where primary prevention has been increasingly successful (2, 3). Cardiovascular epidemiologic research at the University of Gothenburg recognized PA as a factor of importance early on and thus included PA related questions in the work up of studies with large cohorts (4-6). A 4-level scale was introduced in the late 1960:s by Saltin and Grimby (7) and has been used extensively since then. With this background it is of interest to record physical activity one year and one month prior to certain types of elective surgery and to study the relationship of PA to surgical complications and recovery is of interest. The aim of this study is to investigate whether a higher physical activity prior to a surgical procedure reduces hospital stay, sick leave and the complication rate. A secondary aim is to investigate the effect of preoperative physical activity on the rate of resumption of QoL and normal physical function.
This is a Phase I, multi-center, Dose-Escalating, Safety Study of an Intravenously Administered Pegylated Liposomal Mitomycin-C Lipid-based Prodrug (PL-MLP, PROMITIL) in Cancer Patients with Solid Tumors. The study comprised of: Escalated cohorts A-H: 27 male or female participants, ages 18-80, BMI 18-36 diagnosed with inoperable, recurrent or metastatic malignant solid tumors, deemed incurable, and who have failed to respond to standard therapy or for whom no standard therapy is available. Eligible subjects will be assigned, successively in order of accrual, to one of eight cohorts, to receive escalating doses of intravenously infused PROMITIL. PROMITIL will be administered as an intravenous infusion. Dose escalation will only proceed in the absence of dose-limiting toxicity (DLT). For this purpose, each cohort will only begin its first cycle of PROMITIL when the cohort preceding it has successfully completed its first 4-week cycle without any signs of DLT. Expanded cohort: 17 adult patients with metastatic CRC. The purpose of this expanded cohort is to further evaluate the safety of Promitil and to search for signs of antitumor activity of Promitil in this specific patient population. Combination Cohort (Promitil concomitantly with Capecitabine): 23 adult patients with metastatic CRC. Triple combination Cohort: 13 additional subjects with metastatic CRC, received combination of Promitil concomitantly with Bevacizumab (5 mg/kg) on day 1 of a 28 day cycle and Capecitabine on days 1-14 of a 28 day cycle. 3 weekly cohort- 9 subjects with metastatic CRC will receive Promitil and Bevacizumab (7.5 mg/kg) on day 1 of a 21 day cycle.
