Filter by:The purpose of the present study is to investigate the benefit of anti-cancer therapy administered on the basis of drug sensitivity testing. This concerns colorectal cancer patients who have previously received standard treatment.
This observational clinical cohort study aims to evaluate the clinical utility of LiverMultiScan in quantifying liver health prior to liver resection or TACE. The results will enable further developments in scanning protocols and software, and clearly define the relevance of applying this technology as part of the pre-operative assessment of the patient being considered for liver resection or TACE.
Colo-rectal cancer is still one of the leading causes of cancer death worldwide. In France, approximately 40 500 new cases are diagnosed each year. With more than 17 500 deaths in France in 2011, colo-rectal cancer is responsible for more than 12% of all cancer deaths, the overwhelming of deaths occurring in patients with metastatic disease. Many studies highlight the fact that colo-rectal cancer has immunogenic properties and that host immune responses can influence survival. Recent data have provided a clearer understanding of the factors limiting the antitumor immune response in colo-rectal cancer. One of the most critical checkpoint pathways responsible for mediating tumor-induced immune suppression is the programmed death-1 (PD-1) and PD ligand 1 (PD-L1) pathway. PD-1 is expressed on activated immune cells and can link to PD-L1 express on Antigen-Presenting-Cell. Usually, this pathway is involved in promoting T-cells tolerance and preventing tissue damage in settings of chronic inflammation. In pathological context, the PD-1/PD-L1 pathway contributes to immune suppression and evasion. Many human solid tumors including colo-rectal cancer express PD-L1, and this expression is associated with a worse prognosis. The interaction of PD-1 with the ligand PD-L1 inhibits T-cell proliferation, survival, and effectors functions; induces apoptosis of tumor-specific T cells; promotes the differentiation of CD4+ T cells into immunosuppressive regulatory T cells; and increases the resistance of tumor cells to cytotoxic T lymphocytes attack. Thus, the blockage of the PD-1/PD-L1 interactions represents a logical target for cancer immunotherapy and in particular colo rectal cancer immunotherapy strategy. Preclinical studies have shown that PD-L1 blockade improves the immune response by restoring T-cell effectors functions. Recent work in two in vivo tumor models shows a strong interest in using an anti-PD-L1 in combination with standard treatment of colo-rectal cancer (FOLFOX). In these models, the survival of mice that are treated with the combination therapy reached 40% when no mice were alive with FOLFOX treatment alone. This result may be explained, in one hand by cytotoxicity of 5FU and in the other hand by the restoration of anti-tumor immune activity of anti-PD-L1. These results suggest that the combination of chemotherapy with immunotherapy would act synergistically in patients with colo-rectal cancer. Research Hypothesis: Combination of chemotherapy (FOLFOX) with immunotherapy association (anti-PD-L1 + anti-CTLA-4) would act synergistically in patients with colo-rectal cancer.
National trial, multicenter, randomized, phase II comparing treatment intensification with hepatic arterial infusion chemotherapy plus systemic chemotherapy (CT) to systemic chemotherapy alone in patients with liver-only colorectal metastases (CRLM) considered still non resectable after at least two months of systemic induction chemotherapy.
This research study is studying a drug as a possible treatment for p53 mutant metastatic colorectal cancer. The drug involved in this study is: -Lamivudine
To estimate progression-free survival at one year in elderly patients with RAS/BRAF wild-type unresectable mCRC and good performance status treated with FOLFIRI + panitumumab as first-line therapy. The clinical hypothesis of this study is that the combination of panitumumab and FOLFIRI is a good treatment option in elderly patients with good performance status and RAS/BRAF wild-type unresectable mCRC. Another purpose of this clinical trial is to determine the RAS/BRAF mutation status in liquid biopsies at baseline and at the time of disease progression.
This study is being done to look at the safety and response to the combination of two investigational drugs, tremelimumab and durvalumab, when given after radiation therapy for patients with microsatellite stable (MSS) metastatic colorectal cancer. Tremelimumab and durvalumab recognize specific proteins on the surface of cancer cells and trigger the immune system to destroy the cancer cells. In order to learn more about certain characteristics of colorectal cancer tumors, this study includes special research tests using samples from diagnostic tumors, fresh tumor samples from an area where the cancer has spread, and blood samples.
RAS genotyping is mandatory for the prescription of anti-EGFR (epidermal growth factor receptor) therapies in patients with metastatic colorectal cancer. The standard genotyping is assessed on formalin-fixed paraffin embedded tumour tissue. This study compares RAS and BRAF genotyping results achieved in analyzing circulating plasma DNA using OncoBEAM™ technique with those achieved using the standard genotyping techniques and formalin-fixed paraffin embedded samples.
Famitinib is a tyrosin-inhibitor agent targeting at c-Kit, VEGFR2, PDGFR, VEGFR3, Flt1 and Flt3, whose anti-tumor and anti-angiogenesis effects have been validated in preclinical tests. In PhaseⅡb study, a significantly improved Progression Free Survival (PFS) was found in patients with advanced colorectal cancer treated with Famitinib compared to placebo. On the other hand, the toxicity of Famitinib was manageable in both PhaseⅠand Ⅱb studies. The purpose of this study is to determine whether Famitinib can improve Overall Survival (OS) compared with placebo in total 540 patients with advanced colorectal cancer who have failed in previously received at least two lines of standard chemotherapy.
This is a single center, open label dose frequency escalation study of CryoVax®. personalized anti-tumor vaccine protocol combining the cryoablation of a selected metastatic lesion with intra-lesional immunotherapy with AlloStim®. The in-situ (in the body) cancer vaccine step combines killing a single metastatic tumor lesion by use of cryoablation in order to cause the release of tumor-specific markers to the immune system and then injecting bioengineered allogeneic immune cells (AlloStim®) into the lesion as an adjuvant in order to modulate the immune response and educate the immune system to kill other tumor cells where ever they reside in the body.
