There are about 5241 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.
Transfusion of red blood cells is an everyday practice in critical care with the primary aim of restoring adequate tissue oxygenation. However, blood transfusion may also be harmful and costly, therefore a so called restrictive transfusion regime has been suggested by recent guidelines. These transfusion guidelines consider certain levels of hemoglobin as transfusion trigger, which on its own gives little information if any about the balance between oxygen delivery (DO2) and consumption (VO2). Hence, there is a clear need for additional physiologic transfusion trigger values. One of the potentially useful and easily obtainable physiological parameters is the central venous oxygen saturation (ScvO2), which has been shown to be a potential transfusion trigger value in hemodynamically stable but anemic patients. However, the role of ScvO2 as a transfusion trigger value was examined only in a retrospective observational study and in animal experiment. The normal value of ScvO2 in a resting adult at rest is around 70-75%, which is the product of the VO2 and DO2 relationship. Low ScvO2 usually indicates inadequate DO2. It was found in an observational study that if ScvO2>70% before transfusion due to transfusion only the value of hemoglobin increased but the value of ScvO2 did not change. This finding indicates that the DO2 may have been adequate in spite of the low hemoglobin value and the transfusion may have been unnecessary. In one of their recent animal experiments, the investigators reported that in an isovolemic-anemia model the value of ScvO2<70% was only reached when the value of hemoglobin was far less, 59 g/L, than the recommended lowest value of 70g/L as transfusion trigger by guidelines. Despite the pathophysiological rationale and the encouraging results of retrospective studies and animal experiments, prospective randomized trials in order to test the effects of an ScvO2-assisted transfusion protocol are yet to be performed. The aim of this study is to investigate the effects of an ScvO2-assisted transfusion protocol as compared to the guideline-based, hemoglobin levels guided transfusion practice.
To investigate how pulse wave velocity, aortic augmentation index and the arterial pulse wave given by the Arteriograph contributes to preoperative assesment, intraoperative and intensive care monitoring.
Phase 1 dose escalation will determine the first cycle dose-limiting toxicities (DLTs), the maximum tolerated dose (MTD), the biologically effective dose and recommended Phase 2 dose (RP2D) of repotrectinib given to adult subjects with advanced solid malignancies harboring an ALK, ROS1, NTRK1, NTRK2, or NTRK3 gene rearrangement. Midazolam DDI substudy will examine effect of of repotrectinib on CYP3A induction. Phase 2 will determine the confirmed Overall Response Rate (ORR) as assessed by Blinded Independent Central Review (BICR) of repotrectinib in each subject population expansion cohort of advanced solid tumors that harbor a ROS1, NTRK1, NTRK2, or NTRK3 gene rearrangement. The secondary objective will include the duration of response (DOR), time to response (TTR), progression-free survival (PFS), overall survival (OS) and clinical benefit rate (CBR) of repotrectinib in each expansion cohort of advanced solid tumors that harbor a ROS1, NTRK1, NTRK2, or NTRK3 gene rearrangement.
This study is a two-arm, interventional, prospective, open-label, multi-center clinical trial with randomized and non-randomized study groups to evaluate the safety and effectiveness of faecal microbiota transplantation (FMT) for the treatment of adult patients suffering from primary or recurrent Clostridium difficile infection (CDI), using a novel, standardized microbiota transplantation system.
The aim of the present proposal is to investigate the development of distinct morphological, functional, biochemical and molecular aspects of short- and long-term sport-induced changes in the heart, to get a better understanding on the (patho)physiology of athlete's heart. The main goal of our research is to deepen our knowledge on the proper differentiation between beneficial (physiological) and harmful (pathological) consequences of professional sport, thereby effectively preventing potential cardiovascular complications of athletes.

Comparative study on surgery versus definitive radiation therapy in primary localized sacral chordoma
The rate of lens autofluorescence will be compared in diabetic and non diabetic patients with/without atherosclerotic vascular diseases to evaluate if it is associated with the risk of cardiovascular diseases.
An increasing number of specific procedures have been described for the surgical repair of pelvic organ prolapse (POP) and concomitant stress urinary incontinence (SUI). The investigators introduced an alternative operative method for POP-Q II-III repair and anti-incontinence with the trans vaginal mesh (TVM) anterior edge fixed to the periurethral tissues at the level of mid-urethra. The efficacy and short- and long-term complication profile, of this new surgical technique as compared with those of non-modified TVM.
This is a prospective, multicenter, open-label, randomized, controlled, parallel Phase 3 study with an open-label single-arm extension period to evaluate pharmacokinetics (PK), safety and efficacy of macitentan in children with pulmonary arterial hypertension (PAH).
