NCT ID: NCT00973219 Completed - Chronic Hepatitis B Clinical Trials

Hepatitis B Surface Antigen(HBsAg) Loss in Chronic Hepatitis B Patients With Low Viral Load

LVL
Start date: September 2009
Phase: N/A
Study type: Interventional

Rationale: Worldwide, approximately 400 million people are chronically infected with hepatitis B virus (HBV). Chronic HBV infection increases the risk of developing cirrhosis, hepatic decompensation and hepatocellular carcinoma (HCC). The risk of developing hepatocellular carcinoma is highest in HBeAg positive patients with high HBV DNA levels, but still the relative risk remains 10 for HBeAg negative patients. Furthermore it has been shown that when HBsAg is cleared before cirrhosis has developed, the prognosis is excellent. Recently the investigators have shown that HBeAg negative patients with high HBV-DNA load and low baseline HBsAg levels had a significantly higher HBsAg clearance (positive predictive value of 85%) after combination therapy with peginterferon alfa2a (Peg-IFN) and adefovir. Based on these results, a trial was designed to investigate whether combination of a nucleos(t)ide analogue combined with PegIFN, could also provoke a high rate of HBsAg clearance in chronic hepatitis B patients with low (HBV DNA <20,000 IU/mL) viral load. Study design: This is a three arm open-label prospective randomized controlled trial. 150 patients will be enrolled into the study after assessment of eligibility. All patients must have documented HBsAg positivity for longer than 6 months, HBeAg negativity, anti-HBe positivity, HBV DNA < 20,000 IU/mL and ALT < 5 * upper limit of normal. Patients with a Child Pugh class B or C will be excluded. Group 1 will consist of patients treated with Peg-IFN and adefovir, group 2 will consist of patients treated with Peg-IFN and tenofovir and group 3 will consist of untreated controls. Patients in group 1 and 2 will receive medication for the period of one year. For enrolment into the study a liverbiopsy at time of enrolment is compulsory and is advisable at end of treatment (week 48). Study population: The study population will consist of 150 patients chronically infected with hepatitis B virus with low viral load and HBeAg negativity. Main study parameters/endpoints: The aim of this study is to investigate what proportion of HBeAg negative, inactive carriers of the hepatitis B virus with low (< 20,000 IU/mL) load will lose HBsAg when treated with nucleot(s)ide analogue/Peg-IFN combination therapy. In this study the investigators hypothesize that both treatment with peg-interferon and ADF or Peg-IFN and TDF in HBeAg negative chronic hepatitis B patients with low HBV DNA viral load will induce a high rate of HBsAg loss, comparable to that in patients with high viral load after treatment with ADF and Peg-IFN.

NCT ID: NCT00971646 Completed - Osteoporosis Clinical Trials

Cohort Study: Perceptual Urge Sensation

Start date: June 2010
Phase:
Study type: Observational

Over the past few years it has become clear that our understanding of bladder physiology is inadequate to explain urge incontinence. This has forced us to re-evaluate what we know and do not know about bladder function and dysfunction. This has led to the identification and study of novel systems within the bladder that may contribute to abnormal sensations. The investigators now suspect that the organic changes occurring in the bladder are not the whole story. For one group of patients with pathological urge there is growing evidence suggesting that there may be a strong psychological component. The idea now being put forward is that normal afferent peripheral information is perceived as abnormal and excessive, resulting in an increased desire to go to the bathroom: 'perceptual urge'. It is important to identify this group of patients since it will direct their treatment towards more cognitive approaches. Also, if such a psychological aetiology can be eliminated it would lead to a more focused and effective management of peripheral pathology with surgery or pharmacology.

NCT ID: NCT00971542 Completed - Pandemic Influenza Clinical Trials

NCT ID: NCT00970970 Completed - Clinical trials for Renal Cell Carcinoma

Visualizing Vascular Endothelial Growth Factor (VEGF) Producing Lesions in Von Hippel-Lindau Disease

VHLimage
Start date: September 2009
Phase:
Study type: Observational

Von Hippel Lindau disease (VHLD) is an inherited syndrome characterized by vascular malformations, kidney cancer, adrenal gland and pancreas tumors. The VHL protein is not functional in the different disease associated lesions which results in production of high amounts of vascular endothelial growth factor (VEGF). Currently there are no clinical, radiographic or molecular markers that can predict the natural history of a given lesion. With 89Zr-bevacizumab positron emission tomography (PET) scanning, VEGF can be visualized and quantified. The investigators hypothesize that 89Zr-bevacizumab PET imaging is a useful tool to predict the behaviour of disease associated lesions in patients with VHLD. Adult patients with VHLD who have had routine magnetic resonance imaging (MRI) scans of central nervous system (CNS) and abdomen will undergo a 89Zr-bevacizumab PET scan. MRI will be repeated within 12 months.

NCT ID: NCT00970632 Completed - Clinical trials for Benign Prostatic Hyperplasia (BPH)

NCT ID: NCT00970619 Completed - Clinical trials for Acute Thrombosis of Deep Veins of Proximal Lower Extremity

DUTCH CAVA-trial: CAtheter Versus Anticoagulation Alone for Acute Primary (Ilio)Femoral DVT.

NL28394
Start date: May 2010
Phase: Phase 3
Study type: Interventional

Rationale: Iliofemoral deep venous thrombosis (IFDVT) is associated with significant post thrombotic morbidity. The presence of both obstruction and reflux significantly increases the chances for development of post-thrombotic syndrome (PTS). Early thrombolysis may reduce the incidence of PTS as compared to treatment with conventional anticoagulant medication alone. Improvement of the health related quality of life (HRQOL) has been reported after surgical clot removal. The investigators hypothesize that such improvements could also be reached after catheter-directed thrombolysis (CDT). Objective: To assess whether CDT for the treatment of IFDVT can safely and effectively reduce post-thrombotic morbidity after one year. The secondary objective is to study whether CDT intervention has a positive effect on the HRQOL of patients with IFDVT and to assess late PTS. Study design: Prospective, multicenter, single-blind, allocation concealed, randomized controlled trial Study population: All consecutive patients with IFDVT presenting at the emergency or outpatient departments of the participating centers. The thrombus should not be older than 14 days at randomization. Intervention: After randomization patients will be allocated to either conservative anticoagulant treatment or to CDT combined with conservative anticoagulant treatment. Main study parameters/endpoints: The primary efficacy outcome is the proportion of PTS at one year; a decline in PTS incidence from 25% to 8% is anticipated. The secondary outcome is the Health related Quality of life. The principal safety outcome is major bleeding during anticoagulant therapy. Bleeding as well as events of recurrent thrombosis will be monitored. Measurements of markers of coagulation and inflammation will be performed during follow-up. After CDT the patency of the venous system in the affected lower limb will be assessed as well as the percentage of clot lysis. The development of late PTS during follow-up will also be monitored. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: For patients who are randomized to CDT a hospital stay for 24-96 hours is mandatory. All patients will undergo additional imaging by magnetic resonance venography and air phletysmography (if available) at baseline and after 12 months; blood will be taken at these visits. Clinical follow-up visits will be matching usual care at 3, 6, 12 months. Health-related quality of life (HRQOL) questionnaires will be filled out by all patients at baseline, 3, 6 and 12 months after the event; and once a year during the entire study duration. Further treatment will be in accordance with current guidelines for antithrombotic treatment. There may be an enhanced risk of bleeding in the thrombolysis group. The expected benefit is reduction of PTS from 25% to 8%, together with an improved quality of life.

NCT ID: NCT00969657 Completed - Rectal Cancer Clinical Trials

Validation of a Predictive Model After Complete Response in Rectal Cancer

Thunder
Start date: August 2009
Phase: N/A
Study type: Observational

Background of the study: Prediction of rectal tumor response after chemoradiotherapy (CRT) might be helpful in individualizing treatment strategies, i.e., selecting patients who need less invasive surgery or another radiotherapy strategy instead of resection. For rectal cancer it is known that 10-30% of the patients will respond with a pathologic complete response (pCR) after CRT. From a retrospective study with multivariate analysis of both clinical and 2-[18F] fluoro-2-deoxy-D-glucose and positron emission tomography (FDG-PET) data, it was found that adding FDG-PET data collected before and after CRT leads to a more predictive model compared to evaluating only pretreatment clinical data. To validate this model, this registration study is proposed. Furthermore, it has been found that FDG-PET during treatment is very predictive for response and a more favorable time point to adapt treatment. Also, there are indications that adding blood biomarkers to the data, results in higher accuracy for response prediction compared to clinical and imaging data alone. Therefore, FDG-PET during treatment and blood sampling are included in the protocol to improve the accuracy of the prediction models. Objective of the study: The long-term research objective is to be able to select rectum cancer patients who could receive a less invasive treatment. If prediction of response is possible, surgery may be avoided when complete response after chemoradiotherapy is expected or performed with smaller incisions if stage reduction is significant. This support decision system helps to individualize patient treatment and can improve the quality of life for the patient. Study design: 28x radiotherapy. On day 15 of radiotherapy en 8 weeks after radiotherapy: 1 PET-CT scan Before radiotherapy, on day 15 and 8 weeks after radiotherapy: blood sample taken.
