Active clinical trials for "Colorectal Neoplasms"

This is a clinical research study of an investigational (FDA IND-BB 10091) treatment for patients with advanced colorectal cancer that no longer responds to standard therapies. The treatment is being evaluated for its effect on tumor growth. It consists of the placement (implantation) of small beads that contain mouse renal adenocarcinoma cells (RENCA macrobeads). The cells in the macrobeads produce substances that have been shown to slow or stop the growth of tumors in experimental animals and veterinary patients. It has been tested in 31 human subjects with different types of cancers in a Phase I safety trial. Phase II studies in patients with colorectal, pancreatic or prostate cancers are in progress

Despite the advances in the medical treatment of unresectable liver metastases from colorectal cancer there is currently no curative treatment option available for these patients. Decitabine is a cytidine analog with proven anti-neoplastic activity in patients with acute myeloid leukemia and myelodysplastic syndromes. Decitabine causes demethylation of the DNA strands of replicating cells. Hereby decitabine treatment demethylates the promoter regions of tumor suppressor- and cancer testis antigen encoding genes leading to expression of these genes by the cancer cells. The hepatic arterial route for administration of cytotoxic drugs has been widely explored in treatment of colorectal cancer liver metastases because these metastases depend for their blood flow from this artery (as opposed to the normal liver tissue that is mainly dependent from the portal vein). By investigating the administration of decitabine by hepatic arterial infusion the investigators intend to explore the potential advantage of minimizing the systemic exposure (and toxicity) and maximizing the concentration of decitabine within the liver metastasis. The primary objective of this phase I will be to establish the recommended dose for decitabine by HAI for further use in phase II trials. The most important secondary objective will be to document the effect of decitabine by HAI on the expression of cancer testis antigens by the colorectal cancer cells, serving as a reference for potential further exploration of decitabine by HAI in combination with cancer immunotherapy

The purpose of this study is to compare the effects and safety of Anlotinib with placebo in patients with metastatic colorectal cancer refractory to standard chemotherapies.

This open-label, prospective, single-arm, multicenter study will evaluate the relationship of the markers of inflammation and progression-free survival (PFS) in participants with previously untreated metastatic colorectal cancer. The study consists of two phases: Phase A treatment: oral capecitabine plus infusional oxaliplatin (XELOX) plus bevacizumab, or modified infusional 5-fluorouracil (5-FU), leucovorin (LV) and oxaliplatin (mFOLFOX6) plus bevacizmab administered until first disease progression. Participants will then continue with Phase B treatment: infusional 5-FU, LV and irinotecan (FOLFIRI) plus bevacizumab until second disease progression. The anticipated time on study treatment is 4 years.

Early-stage colorectal cancer(CRC)is localized and resectable, but 20% of the patients have metastatic disease at the time of diagnosis and 50% of all patients eventually die of the disease. The most frequent site of colorectal metastases is the liver, which accounts for 30% to 60% of cases. In these patients, the extent of liver disease is the main determinant of survival. Hepatectomy is the only potentially curative therapy for colorectal liver metastases (CLM), but when traditional criteria for resectability were used, only 10% of patients were candidates for surgical resection. Although adjuvant systemic therapy after resection of primary colorectal tumors is well established, there are relatively few data on the use of postoperative therapy vs. surgery alone in patients who have undergone resection of liver metastases. In this trial, the absolute increase in the 3-year PFS rate with the addition of FOLFOX4 was a modest but significant 9% in patients who had resection (from 33% to 42%; P = .025). For improving survival in patients with CLM, several studies with biologic agents have been tried. The use of bevacizumab, a monoclonal antibody against vascular endothelial growth factor (VEGF), has resulted in increased response rates in patients with stage IV colorectal cancer and improved OS and PFS. In an ongoing phase II trial presented in ASCO 2008, in patients who were potentially curable through resection of liver metastases, perioperative treatment with capecitabine and oxaliplatin (XELOX) plus bevacizumab yielded an overall response rate of 73% with stable disease in 21% and a mean PFS of 27 months. Response to chemotherapy significantly correlated with a prolonged PFS (P < .001). On the basis of these backgrounds, we designed a phase II study to compare the effectiveness of combination chemotherapy with perioperative or postoperative bevacizumab treatment in patients with CLM.

This is a single-centre, single-arm open-label proof-of-concept study to analyze the imaging (DCE-CT,CEUS and Quantitative US) effects of neoadjuvant bevacizumab and SBRT on colorectal metastases to the liver. Patients will receive 2 doses of bevacizumab 5mg/kg IV prior to SBRT. The second dose of bevacizumab will be given 2 weeks after the first dose of bevacizumab and within 48 hours of starting the first dose of SBRT. The SBRT prescription dose will be up to 60 Gy in 6 fractions, delivered on alternating weekdays for 2 weeks. Total SBRT dose will be determined by size of target lesion, liver sparing and organs-at-risk dose constraints. DCE-CT, CEUS and Quantitative US will be performed within 7 days prior to the first dose of bevacizumab, after the second dose of bevacizumab and within 7 days of completing SBRT.

The purpose of this study is to establish the safety and tolerability of BKM120 when combined with mFOLFOX6 and to define the maximum tolerated dose of BKM120 in this combination in advanced solid tumors including metastatic pancreatic cancer.

The purpose of the study is to explore the influence of BRAF and PIK3K status on the efficacy of FOLFIRI plus Bevacizumab or Cetuximab, as first line therapy of patients with RAS wild-type metastatic colorectal carcinoma and < 3 circulating tumor cells

The Primary Phase I objectives are to determine the recommended phase II dose for the capecitabine and aflibercept doublet combination; and to describe any dose limiting and non-dose limiting toxicities. The Phase II Primary objective is to determine progression free survival associated with this regimen. The Phase II secondary objectives are to determine response rate associated with this regimen; to determine overall survival associated with this regimen; and to explore any correlation of clinical outcome with baseline and on treatment changes in blood-based angiogenesis biomarkers. This open-label, non-randomized phase I/II trial is designed to assess the safety, tolerability and RPTD of capecitabine plus aflibercept in adult subjects with metastatic colorectal cancer.

This is an open label, multi-center, Phase 2 study of BBI608 in combination with cetuximab, panitumumab or capecitabine in patients with advanced colorectal cancer.
