Active clinical trials for "Thrombosis"

Peripherally Inserted Central Catheters (PICCs) are commonly used in patients with cancer to administer chemotherapy and supportive care medication. However, PICCs and other medical devices that come into contact with blood increase the risk of blood clots (thrombosis) inside the blood vessels. Conventional blood thinners (anticoagulants) may reduce the risk of thrombosis but they also increase the risk of bleeding. CSL312, a monoclonal antibody that inhibits the activated blood clotting factor 12 (FXIIa) will be assessed for its potential to prevent thrombus formation in subjects with cancer at risk of PICC-associated thrombosis.

Hepatic artery thrombosis (HAT) represents a major cause of graft loss and mortality after Pediatric liver transplantation. Ticagrelor (a new reversible inhibitor of P2Y12 receptor with faster onset of action and greater platelet inhibition) was used to treat patients with pediatric post-transplant hepatic artery thrombosis (HAT) compared to low molecular weight heparin.

The study purpose is to perform a preliminary, comparative evaluation of the Hydrophilic Biomaterial technology to confirm the performance of the catheter, by using UltraSound technology in-vivo.

A randomized controlled trial to study the efficacy and safety of Dabigatran in Cirrhotic patients who develop PVT.In this study the patients who meet the inclusion criteria will be randomized to either receive Dabigatran or placebo [multivitamin tablet]. Blood samples will be taken &Imaging will be done accordingly to notice progression or recanalization of PVT.The patients are followed up every 2 months up to 18 month .Then statistical analysis will be done to find whether the Dabigatran is efficacious in cirrhotic patients for recanalization of PVT.

Hepatocellular carcinoma (HCC) is the fourth most common cancer in China, with a crude incidence rate of 26.67 per 100,000 population. Moreover, 357,800 new liver cancer cases are predicted to be diagnosed in China in 2020. HCC represents approximately 90% of all cases of primary liver cancer. HCC has a high predilection for portal vein invasion, which occurs in 44-62% of living patients with HCC. Patients with PVTT usually have an aggressive disease course, decreased liver function reserve, limited treatment options, thus worse overall survival. Among untreated HCC patients with PVTT, the median overall survival has been reported as low as 2 to 4 months with supportive care. Sorafenib is the first-line treatment for HCC patients with PVTT, however, it has shown unsatisfactory benefit. Notably, sorafenib combined with TACE significantly improved the TTP over sorafenib alone, albeit for no more than 1 month in the median TTP, and the median OS was not significantly prolonged. A promising drug-lenvatinib was approved in China on September 2018, in the China patients subgroup analysis showed an encouraging results. Lenvatinib group had showed a significant benefit in TTP, PFS and ORR. Also median overall survival time was significantly improved in China subgroup (Lenvatinib group: 15 months VS Sorafenib group: 10.2 months). However, REFLECT didn't enrolled patients who had tumors invading the maint portal vein. The mechanisms of lenvatinib or sorafenib combined with TACE were still unknown, and clinical data were limited. This study was to explore lenvatinib plus TACE versus sorafenib plus TACE for HCC with PVTT: efficacy and safety. Biomarkers expression of VEGFR, FGFR, FDGF-α, IL-2,etc would be detected to find the difference between the two groups, finally to analyze the relationship between clinical outcomes and biomarkers' expression. A better treatment modality to HCC with PVTT patients would be expected and promoted.

The proposed study is an open-label, single-center, single arm phase 1b study to evaluate the safety and efficacy of radiotherapy plus sintilimab for HCC with PVTT.

To determine whether aspirin is more effective than placebo for the prevention of recurrent symptomatic venous thromboembolism when given for at least two years after the initial 6-12 month of oral anticoagulant therapy in patients with idiopathic venous thromboembolism

The purpose of this study is to determine whether adding clopidogrel to aspirin after coronary bypass operation (CABG) improves graft patency, in patients that have preoperatively increased platelet activity(hypercoagulable) and therefore greater risk of graft occlusion( thrombosis).

Can a post-operative analysis using a simple blood test (Thromboelastography(TEG®)) and Platelet Mapping Assay (PMA™) be able to detect the occurence of clotting or bleeding complications in patients on blood thinning (anti-platelet) agents?

The response to warfarin varies greatly among individuals. Some of this variability can be ascribed to genetic polymorphisms in the gene encoding for CYP2C9, the enzyme mediating the metabolism of S warfarin. In addition genetic polymorphism in other genes (i.e. VKORC1, factor VII) have been shown to account for some of the variability in the response to warfarin irrespective of CYP2C9.The present study has several segments: Evaluation of the relationship between genetic polymorphisms in the genes encoding for CYP2C9, VKORC1 and factor VII and warfarin maintenance dose at steady state. This study is a confirmation of previous data in our own population. Evaluation of relationship between genetic polymorphisms in the genes encoding for CYP2C9, VKORC1 and factor VII and warfarin loading dose during the induction period. Testing the hypothesis that warfarin loading based on the individual's combined CYP2C9, VKORC1 and factor VII genotype may be more efficient and associated with reduced adverse drug effects.
