ABSTRACT: This is a single-site, open-label continued access study/treatment protocol under a treatment IDE. In addition to treating patients, the primary objective of this study is to assess the safety of using the Medtronic SynchroMed II programmable pump combined with the Intera tapered catheter for hepatic artery infusion (HAI) of a standard chemotherapy (FUDR) drug for adults with a clinical or biopsy-proven diagnosis of colorectal cancer metastatic to the liver or intrahepatic cholangiocarcinoma.
After successful implantation, the combined pump and catheter system will be evaluated using a nuclear scan in the postoperative period, which is standard procedure to confirm that the pump is functioning prior to HAI of FUDR. Monitoring for safety will include a record of residual pump volume when it is emptied (every 2-12 weeks depending on whether the pump is being used for chemotherapy infusion) to determine if the pump is still working and surveillance of routine cross-sectional imaging (usually every 2-6 months) for any sign of a pump or catheter problem. Patients will be monitored for the safety of the pump/catheter combination for up to 5 years or pump removal/study withdrawal.

Project description:Due to discontinuation of the Codman C3000 pump, an alternate device is necessary to continue serving patients in need of hepatic arterial infusion chemotherapy. This study aims to test the safety of hepatic artery infusion pump placement, a standard surgical procedure, and intraarterial chemotherapy initiation with the standard medication floxuridine (FUDR), using the Medtronic Synchromed II pump combined with the Codman arterial catheter in patients with unresectable (not removable by surgery) liver metastases from colorectal cancer and unresectable intrahepatic cholangiocarcinoma. This study will determine if complication and pump loss rates will be similar to previously published rates for the Codman system.
Project description:This study is being done to answer the following question:
Is the combination of the Medtronic pump and the Codman catheter device a safe alternative to the C3000 Codman pump for delivering chemotherapy directly into the liver of patients with metastatic colorectal cancer or cholangiocarcinoma?

Project description:AF is characterized by structural and electrical remodeling, including atrial enlargement, fibrosis, inflammation, and ion-channel alteration, which frequently results in arrhythmia recurrence and maintenance.However, the gene expression profiles signaling pathways in the atria during the development of AF induced by Ang II remain unknown All mice were infused with Ang II (2000 ng/kg/min) using an osmotic pump for 1, 2 and 3 weeks. At the end of Ang II infusion, intracardiac pacing was performed in these animals by inserting an eight-electrode catheter (1.1 F, octapolar EP catheter, Science) through the jugular vein and advancing it into the right atrium and ventricle.
Project description:Hepatic artery infusion (HAI) with oxaliplatin (OX), systemic 5 fluorouracil (5FU), and leucovorin (HAI/OX/FU) will be implemented using an interventional radiology technique to obviate the need for initial major surgery (catheter placement) in patients who have unresectable liver metastasis from colorectal cancer. The study goal is to reduce tumor size to make possible a complete resection of all lesions. Secondary goals are to reduce or eliminate the complexity usually associated with HAI, to accomplish most or all of the treatment as an outpatient, to reduce costs, and to avoid the hepatotoxicity associated with HAI/floxuridine (FUDR). Oxaliplatin has been selected because of its ease of use, known toxicology, and established efficacy in colorectal cancer.
Project description:The aim of the trial is to compare the objective response rates of FUDR/Oxaliplatin HAI plus CPT-11 and FOLFOXIRI chemotherapy in patients with initially non-resectable metastatic colorectal cancer liver metastases. The patients will be treated with systemic FOLFOXIRI chemotherapy or FUDR/Oxaliplatin hepatic arterial infusion with CPT-11 systemic chemotherapy.
Project description:Interventions: systymic chemotherapy with XELOX combined with HAI of FUDR and Dex
systemic chemotherapy with XELOX alone
Primary outcome(s): overall survival time
Study Design: Parallel Non-randomized
Project description:Acetate, or CFMB (Gpr43 agonist), or saline were administrate to left lobe of interscapular brown adipose tissue (iBAT) by a catheter guided pump. Tissue were harvested after four and seven days of administration.
Project description:This phase III trial compares hepatic arterial infusion (HAI) (pump chemotherapy) in addition to standard of care chemotherapy versus standard of care chemotherapy alone in treating patients with colorectal cancer that has spread to the liver (liver metastases) and cannot be removed by surgery (unresectable). HAI uses a catheter to carry a tumor-killing chemotherapy drug called floxuridine directly into the liver. HAI is already approved by the Food and Drug Administration (FDA) for use in metastatic colorectal cancer to the liver, but it is only available at a small number of hospitals, and most of the time it is not used until standard chemotherapy stops working. Standard chemotherapy drugs work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Adding HAI to standard chemotherapy may be effective in shrinking or stabilizing unresectable colorectal liver metastases.
