There are about 3226 clinical studies being (or have been) conducted in Hungary. 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 prospective observational study is designed to describe the factors determining the success of pulmonary vein isolation (PVI) for patients with persistent atrial fibrillation (AF). These factors - described as left atrial (LA) function - are simultaneously studied by multi-modal techniques in patients undergoing radiofrequency ablation. The simultaneous measurements are conducted before the PVI in AF and after the sinus rhythm converted due to PVI. These measurements include invasive LA pressure monitoring, LA voltage map creation, LA strain evaluation by transthoracal echocardiography, LA scar-mapping by cardiac MRI, defining biomarkers from blood samples. During the one year follow-up period rhythm monitoring is conducted by regular Holter-monitoring. Our aim is to define the predictive values of the above mentioned factors and to create a new score system for predicting PVI success in persistent AF population.
This is a Phase 2, PoC, randomized, placebo-controlled, double blind, international multicentre study to explore the effect of a new antibody to treat patients with Rheumatoid Arthritis
The primary objective of this study is to assess the efficacy of vilaprisan in subjects with uterine fibroids compared to ulipristal The secondary objective of this study is to evaluate the efficacy and safety of different treatment regimens of vilaprisan in subjects with uterine fibroids
This 3-part study will evaluate the efficacy and safety of an oral kallikrein inhibitor, BCX7353, in the treatment angioedema attacks in subjects with Type I or II hereditary angioedema (HAE). In each study part, subjects will treat 3 attacks with BCX7353 (2 attacks) or placebo (1 attack), in a randomly allocated order. In Part 1, the dose of 750mg will be assessed relative to placebo in up to 36 patients. If this is shown to be effective, then a further 12 patients will be enrolled at a 500mg dose (Part 1), followed by a further 12 (if efficacy still shown) at a dose of 250mg (Part 3) to determine the minimum effective dose of BCX7353 compared to placebo for treating HAE attacks. Efficacy will be determined by subject diary entries completed at pre-defined times post-dose.
The humanised IgG4 monoclonal antibody GNbAC1 targets the envelope protein (Env) of the human endogenous multiple sclerosis-associated retrovirus (HERV-W MSRV), which may play a critical role in multiple sclerosis. The study assesses the long-term safety of GNbAC1 in patients with RRMS and the long-term efficacy of GNbAC1 in terms of MRI outcomes, relapse rate, disability and disease progression.
This study is designed to evaluate the dose range for MEDI0382 with respect to blood glucose control and weight loss effects, as well as to further explore the safety profile of MEDI0382.
The aim of the present study is to develop and evaluate a computer-based methods for automated and improved detection and classification of different colorectal lesions, especially polyps. For this purpose first, pit pattern and vascularization features of up to 1000 polyps with a size of 10 mm or smaller will be detected and stored in our web based picture database made by a zoom BLI colonoscopy. These polyps are going to be imaged and subsequently removed for histological analysis. The polyp images are analyzed by a newly developed deep learning computer algorithm. The results of the deep learning automatic classification (sensitivity, specificity, negative predictive value, positive predictive value and accuracy) are compared to those of human observers, who were blinded to the histological gold standard. In a second approach we are planning to use LCI of the colon, rather than the usual white light. Here, we will determine, whether this technique could improve the detection of flat neoplastic lesions, laterally spreading tumors, small pedunculated adenomas and serrated polyps. The polyps are called serrated because of their appearance under the microscope after they have been removed. They tend to be located up high in the colon, far away from the rectum. They have been definitely shown to be a type of precancerous polyp and it is possible that using LCI will make it easier to see them, as they can be quite difficult to see with standard white light.
The purpose of this study is to investigate the psychosocial effects of systemic / family constellation. The method of systemic / family constellation refers to an approach which integrates ideas from family systems therapy with elements from psychodrama. The constellations are conducted in a group based seminar-setting, each seminar lasting two days. Considering the very limited amount of empirical data on this method, the study design is a simple pre-post one with a 6-months follow-up. The study will be observational: the researchers will not manipulate who receives the intervention; instead they invite all clients (individuals from the general population) attending these therapeutic workshops run independently of the research process. Given the limited amount of evidence on this therapeutic method, special attention will be given to monitor potential adverse outcomes to establish intervention safety. It is hypothesized that participation in a family constellation seminar might decrease potential psychological symptoms and will not result in adverse outcomes.
The purpose of this study is to enable continued access to RA101495 for patients with paroxysmal nocturnal hemoglobinuria (PNH) after they complete a RA101495 clinical study.
The purpose of this study is to evaluate the efficacy of pembrolizumab (MK-3745) in the neoadjuvant (prior to surgery) or adjuvant (after surgery) treatment of adults with gastric and gastroesophageal junction (GEJ) adenocarcinoma. The primary hypotheses of this study are that pembrolizumab plus chemotherapy is superior to placebo plus chemotherapy in terms of overall survival (OS), event-free survival (EFS) and pathological complete response (pathCR) rate.
