Filter by:The purpose of this study is to test a new drug called MK-2206 for metastatic colorectal cancer. This drug is being tested in a subgroup of patients with colorectal cancer whose tumors have changes in certain genes that may make them more likely to respond to this new medication. As tumors develop, the cells within the tumor acquire mutations within genes, allowing them to grow more effectively. We will be testing your tumor for mutations involving two genes - KRAS and PIK3CA. Patients whose tumors have a normal copy of the KRAS gene and a mutation within the PIK3CA gene will be eligible to participate in this study. This study is a phase 2 study. The goal of a phase 2 study is to find out what effects, good and/or bad, a new treatment has against a certain type of cancer.
A research study of liver perfusion (how blood flows to the liver over time). We hope to learn whether perfusion characteristics of liver masses may be predictive of response to treatment and whether liver perfusion characteristics can be used to follow response to treatment.
Cetuximab, erlotinib, and panitumumab are all recently FDA approved epidermal growth factor receptor (EGFR) inhibitors that treat a wide variety of tumor types, such as colon, lung, and head and neck. Blockade of the EGFR results in inhibition of multiple downstream pathways, leading to slowed tumor growth. In addition, these inhibitors may enhance anti-tumor immune responses through uncharacterized mechanisms. While producing significant responses in many settings, EGFR inhibitors also result in significant skin toxicity (rash) in a high percentage of patients. Multiple studies have correlated the presence and severity of rash with clinical response. Unfortunately, severe rash can often lead to dose delays, reductions, or even discontinuation of EGFR inhibitors, thus limiting their efficacy. The mechanism of both the rash and its correlation with tumor response is poorly understood. Skin biopsies display a robust leukocyte infiltrate, but a systematic analysis of the type of infiltrating leukocytes, activation state, or homing receptor expression has not been performed. Chemokines and chemokine receptors control leukocyte trafficking to the skin and other tissue sites, and defined receptor profiles for skin-, gut-, and lung-homing leukocytes are well established. In this study, the investigators propose to evaluate the homing phenotype of leukocytes from peripheral blood and skin biopsies of patients receiving EGFR inhibitors. The investigators will use RNA microarrays to evaluate the expression of chemokines and other key genes regulated in skin during treatment. The investigators will utilize in vitro methods to investigate effects of EGFR inhibitors on imprinting of T cell tissue-specific homing receptors. The investigators will examine correlations among the pathologic data, clinical findings, and tumor response. If validated, peripheral blood evaluation could potentially be used as a predictive indicator for patients receiving EGFR inhibitors. This study may also identify novel targets for limiting skin toxicity while receiving EGFR inhibitors, thus allowing maximal dosing and clinical response from these agents.
This is an open-label, non-randomized, prospective, multicentric, Phase IV study evaluating FOLFIRI/ FOLFOX plus cetuximab in the first-line therapy of subjects with KRAS wild-type metastatic CRC.
The purpose of the Phase Ib portion is to find out the highest dose of study drug that can safely be given when tested in a small group of subjects. The purpose of the Phase II portion is to find out how safe the study drug is when taken at the highest dose in a larger group of subjects.
The purpose of this clinical trial is to primarily assess the efficacy of an intensified chemotherapy consisting of a combination of FOLFOXIRI + bevacizumab. The main focus will be laid on the rate of patients who achieve secondary complete (R0)-resectable metastases. The FOLFIRI + bevacizumab as well as the FOLFOXIRI regimens have been shown previously to be both effective in the treatment of advanced CRC with having manageable toxicities. Therefore, an intensified chemotherapy combining these two standard regimens might be a promising therapeutic approach improving the treatment of metastatic disease and outcome of CRC. Patients with advanced colorectal carcinoma of UICC stage IV, and liver and/or lung metasta¬ses only, which are not optimally resectable, will be enrolled in this single-arm phase II study. A minimum of 4 cycles (=8 weeks) of chemo¬therapy prior to surgery is mandatory for all patients. However, patients may withdraw from the study at any time upon their own request. Treatment with preoperative chemothera¬py will continue until 2-4 weeks prior to surgery with the last application of bevacizumab (only FOLFOXIRI) 4 weeks before surgery, at longest 16 cycles (= 32 weeks) for candidates not eli¬gible for surgery. Treatment will be discontinued prematurely at disease progression or unacceptable toxicity. As secondary endpoints the acute and perioperative toxi¬city of preoperative chemotherapy according to NCI CTCAE v 3.0 including all peri-and post-surgical complications as well as progression free survival and overall survival and quality of life will be assessed.
This study aims to investigate the efficacy and safety of the combination of pemetrexed and gemcitabine in heavily pre-treated, chemotherapy resistant colorectal cancer patients with KRAS mutations.
The purpose of this study is to determine the effectiveness of radioactive microsphere infusion as a treatment for liver metastases from colon or rectal cancer. The investigators hypothesis is that the administration of microspheres between first and second line chemotherapy will increase progression-free survival time by about 2.5 months and may also improve tumor response rates to subsequent second line chemotherapy.
This is an observational, non-interventional, uncontrolled, multicentric safety study in subjects with epidermal growth factor receptor (EGFR)-expressing, V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS) wild-type mCRC. The study aims to collect safety data related to Erbitux treatment from a total of at least 400 mCRC subjects from about 35 institutions from the start of treatment with Erbitux until progressive disease, Erbitux-related intolerable toxicities, death, or withdrawal of Erbitux treatment (whichever occurs first).
The primary objective of this study is to evaluate the efficacy of Irinotecan Beads in combination with intravenous cetuximab versus intravenous irinotecan in combination with intravenous cetuximab in the treatment of patients with unresectable liver metastases from colorectal cancer. Secondary objectives are safety and tolerability of hepatic chemoembolization and the question if the addition of aprepitant to standard antiemetic prophylaxis in patients treated by hepatic chemoembolization is safe and will reduce the rate of acute and delayed nausea and emesis.
