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.
Background Hepatic metastases of colorectal cancer (MCC) is quite common and is a major source of morbidity and mortality. There has been evidence to show that hepatic arterial chemoembolisation using DC beads (drug eluting beads, 100-300μm) loaded with irinotecan (DEBIRI) showed improved overall survival when compared to systemic therapy (FOLFIRI), but being larger they have their limitations. New 70-150μm beads are recently available and currently there is limited data concerning its use. Safety of these beads have not been tested in local patients. Hypothesis / Aim To study the safety and pharmacokinetics of the smaller 70-150μm DEBIRI in a pilot study of 5 patients. The smaller 70-150μm beads will be able to deliver a more consistent and higher dose to tumoral tissue with a smaller systemic dose. Being smaller and less embolic, it will also be better tolerated. Patients will also be genotyped for their UGT1A1*28 and UGT1A1*6 polymorphism status as the latter genotypes are associated with decreased clearance of irinotecan and SN-38 in Asian patients. Methods Single centre, pilot study, prospectively recruiting 5 patients with unilobar disease, refractory to systemic chemotherapy The primary endpoints: 1. establish safety and toxicity profile of the irinotecan loaded DEBIRI beads 2. establish pharmacokinetics and systemic exposure of irinotecan and its active metabolite, SN-38. The secondary outcome measurements: 1. the incidence and severity of adverse events, liver function parameters and laboratory abnormalities; 2. response rate, 3. progression free survival 4. overall survival Clinical Significance This treatment modality has the advantage of directly delivering irinotecan to the liver metastases from colorectal cancer. This local mode of drug delivery may result in a higher intratumoral drug concentration and rapid tumour shrinkage leading to downstaging of the hepatic metastatic lesions. These therapeutic outcomes may also downstage patients to hepatic resection.
The main objective of this study is to evaluate the objective response rate at two months (complete disappearance of the disease and partial disappearance of the disease) obtained after administration of combination therapy with cetuximab and irinotecan in the patients with metastatic colorectal cancer. Secondaries objectives will be assessed progression-free survival, overall survival, toxicity, quality of life.
The objective of the program is to provide access to TAS-102 to patients with metastatic colorectal cancer who are refractory to or failing standard chemotherapy, are new to therapy with TAS-102 and in whom therapy with TAS-102 is clinically indicated.
Pancreatic, ovarian and colorectal cancers are difficult to treat using chemotherapy and immune therapies.Currently most patients are offered treatment with a standard chemotherapy drug depending on their cancer type. Recently, laboratory studies have shown that a drug called plerixafor may help the body to overcome resistance to immune therapy. The purpose of this study is to find out if the study drug has the same effect on patients with advanced pancreatic, ovarian or colorectal cancer, as we have seen in our laboratory experiments, and find out the right dose of the study drug to give. This is a 'dose escalation study'. Patients will be recruited slowly and the study team will closely monitor the effect the drug has, until they find the best dose to give. As part of this study, blood and tumour samples will be collected and analysed in our laboratories and the patients cancer will be monitored using two imaging techniques, CT and FDG-PET scans.
The BCCA Oncopanel is a clinical assay being developed to determine genotype status of a prospectively defined set of genes. The purpose of this pilot study is to assess the feasibility and effect on clinical-decision-making of the Oncopanel test. Eligible patients are those with advanced lung, colorectal, melanoma and GIST cancers and patients with diagnosed malignancies being considered for clinical trials.
There is still no perfect treatment suggestion for patients with asymptomatic colorectal cancer with unresectable metastatic disease. Whether patients can benefit from palliative resection of primary tumor or not is still waiting for answer. The investigators hypothesis that asymptomatic metastatic colorectal cancer patients who respond to chemotherapy will benefit from primary tumor resection.
