There are about 1560 clinical studies being (or have been) conducted in Serbia. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This is a study to assess the efficacy and safety of oral Istradefylline (KW-6002) in patients with moderate to severe Parkinson's Disease. While on this study, participants will continue to take their usual, prescribed, stable regimen of Levodopa/Carbidopa or Levodopa/Benserazide therapy plus adjunct Parkinson's medications. Patients will be randomized 1:1:1 to receive either Istradefylline 20 mg per day, or Istradefylline 40 mg per day or an equivalent placebo. Patients will be treated for a 12 week period to demonstrate the effectiveness of Istradefylline in improving Parkinson's disease symptoms (referred to as improvement in patient OFF time) and that Istradefylline has an acceptable safety profile in this group.
Endovascular procedures already brought enormous revolution in the process of treatment of patient with abdominal aortic aneurysm (AAA). It is well defined that early mortality and morbidity is significantly reduced comparing to open repair. The persistent concern is long term durability of devices and their success of aneurysm exclusion in order to prevent rupture. At the moment the best armament to prevent rupture after endovascular exclusion is the watchful waiting and timely reintervention. The main complication that follows this procedure and causing catastrophic long term complications is endoleak. The ideal algorithm to follow up patients after aneurysm exclusion has not been found. In order to reveal endoleak ultrasound is used more than before, however frequent computerized tomography is wasting a lot of costs and exposing patients to irradiation and nephrotoxic contrast. Matrix metalloproteinase activity has been demonstrated in the process of aneurysm development. Imbalance between MMP and its inhibitors TIMP provokes collagenolytic and elastolytic activity that is inducing aneurysmatic degeneration of aortic wall. Due to the previously described connection between aneurysm and MMP activity, it was proved that serum level of MMP-9 is significantly higher in patients with abdominal aortic aneurysm (AAA). Also, higher levels of MMP-9 were discovered in patients with inadequate aneurysm exclusion after endovascular procedure suggesting that degradation of the aortic wall is still ongoing process, not being the case with successfully excluded aneurysm. There might be a potential role of MMP-9 serum level as a biomarker of present endoleak after endovascular aneurysm exclusion. All published trials have shown correlation between MMP 9 activity and presence of endoleak, however, no correlation was made between specific types of endoleak and necessity to reoperation (clinical significance). Additionally there were only four trials presented in the literature investigating low number of patients. Since there is possible value of MMP-9 serum level as biomarker of present endoleak, further studies are necessary. This why we are organizing multicentre trial, that will cover significant number of patients in order to define - Value of MMP-9 as a biomarker of successful initial exclusion - Value of MMP-9 level as predictor of aneurysm shrinkage - Value of MMP-9 level in patients with increased aneurysm diameter and no visible endoleak - Correlation of the MMP -9 serum level with different type of enoleak - Value of MMP-9 as biomarker of successful treatment of endoelak Material and methods Patient with AAA greater then 55 mm in diameter that are candidates for endovascular repair will be selected. Demographic, anatomical and data regarding the procedure will be gathered prospectively. Also serum levels of MMP-9 will be measured before procedure, during the first week before discharge, and after 1,6,12,18,24,36,48 months. On the same day of measuring MMP-9 level control MSCT and ultrasonography exam will be performed in order to collect data regarding the success of exclusion and presence of any endoleak with the accurate measurement of aneurysm diameter changes. Ultrasonography and MSCT exam will be performed by experienced physicians, also preoperative evaluation of anatomical data. In case of reintervention additional questionnaire will be filled regarding anatomical and procedure related data using pre and postoperative ultrasound and MSCT examination, while MMP-9 levels will be measured before procedure and after the procedure using the same protocol as for primary procedure. Statistical analysys Levels of MMP-9 in serum with presence of different types of endoleak will be correlated one week and 1,6,12,18,24,36 48 months after the procedure Anatomical data will be correlated with the decrease in MMP-9 level before and after procedure Levels of MMP-9 in serum after one week and one month will be correlated with further aneurysm shrinkage Level of MMP-9 in serum with type of endoleak will be correlated Level of MMP-9 before and after reoperation will be compared Level of MMp-9 in serum of patients with disappearing endoleaks will be followed Level of MMP-9 in serum of patients with new endoleaks will be followed
The purpose of this study is to evaluate the long-term safety, tolerability and efficacy of lacosamide (LCM) in pediatric subjects.
This is a Phase 2, randomized, rater-blinded, 5-arm, parallel-group trial that will test 4 doses of plovamer acetate against the active comparator Copaxone in subjects with Relapsing Remitting Multiple Sclerosis (RRMS). The trial will be conducted on an outpatient basis for minimum treatment duration of 40 weeks.
The purpose of this study is to investigate the effects of three different exercise programs (e.g. low-intensity, medium-intensity, high-intensity) administered for six months on health-related physical fitness, biochemical variables and general health outcomes in high-risk employees, with about 2000 volunteers will participate in the randomized and repeated-measure study.
The investigators hypothesize that RHB-104 will have greater efficacy than placebo in Crohn's disease.
This is a 2-year, randomized, multicenter, open-label, 2-arm study evaluating the graft function of everolimus and reduced CNI versus MPA and standard CNI in adult de novo renal transplant recipients.
This is prospective, observational study, that will be conducted in two high-volume university interventional cardiology centers. Study population consists of patients with "true" coronary bifurcations (Medina 1.0.1; 0.1.1; 1.1.1) with >50% stenosis in both main (MB) and side branch (SB). Patients are scheduled to undergo percutaneous coronary intervention (PCI) based on clinical findings. Before PCI, patients will undergo multislice CT angiography (MSCTA). MSCTA before PCI for "true" non left main bifurcation lesions can determine atherosclerotic plaque characteristics in MB and SB and predict significant narrowing of SB after provisional stenting. Primary goal is to determine which plaque characteristics of "true" non left main bifurcation lesions in MB and SB, as assessed by MSCTA, can affect the occurrence of SB ostial compromise after provisional stenting. Patients will be seen in the office visit at 1, 3, 6 and 12 months after the procedure. Clinical evaluation and 12-channel ECG are mandatory at each visit. Comprehensive echocardiogram with 2D-strain analysis will be done at 3-month visit. Repeated coronary angiography will be done at 6-month visit, and will include quantitative analysis of previously treated bifurcation lesion.
The role of steroids in the treatment of ulcerative Colitis (UC) is well established, and recommended by professional societies. However, there are no data investigating whether the addition and/or continuation of 5-aminosalicylic agents as combination therapy with systemic corticosteroids is superior to corticosteroids alone in patients with moderate-severe active UC. Thus, in practical terms, the decision regarding 5-aminosalicylic (to add or continue), on top of steroids treatment, is taken on an arbitrary basis. The aim of this study is to compare the efficacy of steroids alone Vs combination of steroids + 5-aminosalicylic in the treatment of moderate-severe UC exacerbation.
This is a prospective, multi-center, non-randomized, single arm clinical trial that will be conducted at up to 40 sites in the United States and Outside United States (OUS). This study will enroll patients with symptomatic ischemic heart disease due to a single de novo lesion contained within a native coronary artery with reference vessel diameter between 2.5 mm and 4.0 mm and lesion length ≤ 24 mm that is amenable to percutaneous coronary intervention (PCI) and stent deployment. All patients will be followed at 30 days, 6 months, 9 months, 1 year and annually for 5 years post index stenting procedure.
