Project description:Trans arterial chemoembolization using Irinotecan Drug-eluting Beads before liver surgery for patients with primarily unresectable colorectal liver metastasis
| 2379485 | ecrin-mdr-crc
Project description:This phase I trial studies the side effects and best dose of irinotecan-eluting beads in treating patients with colon or rectal cancer that has spread to the liver and does not respond to treatment with standard therapy. Irinotecan-eluting beads are tiny beads that have been loaded with irinotecan hydrochloride, a chemotherapy drug. Drugs used in chemotherapy, such as irinotecan hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or stopping them from dividing. This treatment delivers the chemotherapy directly to the tumor area inside the liver instead of to the whole body as with systemic delivery of the drug. Irinotecan-eluting beads may work better that standard chemotherapy in treating patients with colon or rectal cancer that has spread to the liver.

Project description:Background:
* Cancers in other parts of the body often spread to the liver, developing tumors which in many instances cannot be removed with surgery. Liver chemoembolization is a treatment that is routinely performed to control liver tumors in those who cannot have surgery. It has been shown to prolong survival, but does not cure the cancer. During chemoembolization very tiny beads (drug-eluting beads, or DEB) containing chemotherapy drugs (usually doxorubicin) are administered directly into the blood vessels of a liver tumor. The drug within the beads is then released into the tumor whilethe beads temporarily interrupt the tumor s blood supply.
* Irinotecan, a drug commonly given intravenously to treat colon cancer, has been given in chemoembolization procedures in four other studies that have shown that the treatment is generally well tolerated. Researchers are interested in determining whether giving the drug irinotecan directly into the liver using drug-eluting beads is not only well tolerated but also provides a larger dose directly to the tumor as determined by tumor and normal liver tissue biopsies. The liver biopsies are an optional portion of the study.
Objectives:
- To evaluate the safety and effectiveness of chemoembolization with irinotecan for tumors caused by cancer that has spread to the liver.
Eligibility:
- Individuals at least 18 years of age who have melanoma, colon, or another intra-abdominal cancer that has spread to the liver.
Design:
* Participants will be screened with a physical examination, medical history, blood tests, tumor imaging studies, and liver biopsies.
* Participants will receive up to 3 DEB chemoembolization treatments about 6 weeks apart.
* After two treatments, participants will have imaging studies to see if the tumors have shrunk, and those whose tumors have shrunk may have a third treatment.
* Multiple liver biopsies may be performed and blood samples will be taken to determine how much drug is in the tumor and the circulation, and to see how the tumor reacts to the drug.
* Participants will return for followup visits for up to 1 year....

Project description:Purpose: The aim of this study was to evaluate the difference of mRNA and lncRNA in K562 cells treated with vandetanib (1.56 μM) and control (DMSO) by high-throughput sequencing results. Methods: Total RNA was extracted using the RNAfast200 kit according to the manufacturer’s protocol. Then, 200 ng RNA was sequenced with high throughput, and then pathway and GO analysis were used for comprehensive analysis. Finally, RT-PCR method was used to validate in large sample population. Results: High-throughput sequencing results showed that there were significant differences in mRNA and lncRNA in K562 cells treated with vandetanib (1.56 μM) and control (DMSO). Conclusions: It is the first time that we have used high-throughput sequencing to study the difference of mRNA and lncRNA in K562 cells treated with vandetanib (1.56 μM) and control (DMSO). The results of sequencing show that the expression of mRNA and lncRNA is quite different in K562 cells treated with vandetanib (1.56 μM) and control (DMSO).

Project description:An unanticipated complication of the use of bare metal stents in percutaneous transluminal coronary angioplasty is in-stent restenosis resulting in >50% late lumen diameter loss in treated patients. In an effort to reduce in-stent restenosis, drug eluting stents containing the immunosuppressant sirolimus or zotarolimus have recently been developed. We report here the molecular response of arterial tissue to the implanting of these drug-eluting stents.

Project description:BACKGROUND:Transarterial chemoembolization (TACE) is the current standard of care for patients with intermediate-stage hepatocellular carcinoma (HCC) and is also a treatment option for patients with liver metastases from colorectal cancer. However, TACE is not a curative treatment, and tumor progression occurs in more than half of the patients treated. Despite advances and technical refinements of TACE, including the introduction of drug-eluting beads-TACE, the clinical efficacy of TACE has not been optimized, and improved arterial therapies are required. OBJECTIVE:The primary objectives of the VEROnA study are to evaluate the safety and tolerability of vandetanib-eluting radiopaque embolic beads (BTG-002814) in patients with resectable liver malignancies and to determine concentrations of vandetanib and the N-desmethyl metabolite in plasma and resected liver following treatment with BTG-002814. METHODS:The VEROnA study is a first-in-human, open-label, single-arm, phase 0, window-of-opportunity study of BTG-002814 (containing 100 mg vandetanib) delivered transarterially, 7 to 21 days before surgery in patients with resectable liver malignancies. Eligible patients have a diagnosis of colorectal liver metastases, or HCC (Childs Pugh A), diagnosed histologically or radiologically, and are candidates for liver surgery. All patients are followed up for 28 days following surgery. Secondary objectives of this study are to evaluate the anatomical distribution of BTG-002814 on noncontrast-enhanced imaging, to evaluate histopathological features in the surgical specimen, and to assess changes in blood flow on dynamic contrast-enhanced magnetic resonance imaging following treatment with BTG-002814. Exploratory objectives of this study are to study blood biomarkers with the potential to identify patients likely to respond to treatment and to correlate the distribution of BTG-002814 on imaging with pathology by 3-dimensional modeling. RESULTS:Enrollment for the study was completed in February 2019. Results of a planned interim analysis were reviewed by a safety committee after the first 3 patients completed follow-up. The recommendation of the committee was to continue the study without any changes to the dose or trial design, as there were no significant unexpected toxicities related to BTG-002814. CONCLUSIONS:The VEROnA study is studying the feasibility of administering BTG-002814 to optimize the use of this novel technology as liver-directed therapy for patients with primary and secondary liver cancer.

Project description:[original title] Gene expression response to the implantation of drug (paclitaxel)-eluting or bare metal stents in denuded human LIMA arteries. Different clinical outcomes have been observed for paclitaxel-eluting and bare metal cardiovascular stents. The aim of this project was to identify genes that might be associated with the observed clinical outcomes. Human left internal mammary artery (LIMA) was divided into three segments and and two of the segments were fitted with either a paclitaxel-eluting stent or a bare metal stent. The experiment includes three groups: control, paclitaxel-eluting stent, and bare metal stent, respectively. Each group includes four biological replicates (patients 1, 2, 4 and 5).
