There are about 9702 clinical studies being (or have been) conducted in Poland. 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.
Non-commercial phase 2 clinical trial to evaluate the effectiveness, safety and tolerability of treatment using prostate-specific membrane antigen (PSMA) labeled with 177Lutetium in patients with recurrence and/or metastases in adenoid cystic carcinoma originating from the salivary glands of the head and neck region. Patients with PSMA receptor expression confirmed by PET/CT after administration of 68Ga-PSMA I&T will be eligible for treatment.
The aim of this study will be to assess the effectiveness of monitored vit D supplementation in a population of preterm infants and to identify whether the proper vit D supplementation in preterm infants can reduce the incidence of neonatal sepsis and incidence of metabolic bone disease.
About 20% of stroke causes are atherosclerotic strokes caused by carotid artery stenosis. In 2005, 92% of carotid artery interventions in the USA were performed in asymptomatic patients. It should be noted that screening in the general population for carotid artery disease is unwarranted, due to uncertain eligibility criteria for interventional treatment of asymptomatic patients. On the other hand, 10-15% of all patients with a first-ever stroke will experience an ischemic stroke as a result of previously untreated, asymptomatic, significant carotid artery stenosis. Carotid artery angioplasty with stent placement (CAS) has become the second method of revascularization. ed, however, there is a great deal of ambiguity in the application of these criteria, which stems from the ratio of the risk to the possible benefit to the patient of performing the procedure, as well as the cost-effectiveness for health care systems. OBJECTIVES The overall goal is (following the model of measuring fractional flow reserve - FFR) to try to establish a new parameter that could prove helpful in qualifying patients for percutaneous internal carotid artery angioplasty with stent implantation (CAS). Determining whether measuring the pressure gradient across the stenosis will determine which patients will benefit from the CAS procedure. In the absence of convincing evidence on the effects of CAS, especially for so-called asymptomatic patients, it is advisable to establish a parameter that would complement the eligibility criteria that, on the one hand, could prevent strokes in the population of patients with silent internal carotid artery stenosis and, on the other hand, avoid performing the procedure in the absence of benefit. PRIMARY ENDPOINTS: 1. Assessment of cerebral perfusion by magnetic resonanse before and after CAS 2. Assessment of cognitive symptoms using before and after CAS 3. Assessment of neurological symptoms before and after CAS 4. Assessment of otolaryngological symptoms before and after CAS SECONDARY ENDPOINTS: Creation of a non-invasive computed tomography protocol with pressure gradient assessment in patients with carotid artery stenosis. A final version of the algorithm based on a new diagnostic measurement (concentration gradient) ready to be used in the diagnosis of CAS-eligible patients with an implemented function for automatic classification of measurement results that will indicate the group of patients who will benefit from the CAS procedure.
The research study is being done to see if ziltivekimab can be used to treat people who were admitted to hospital because of a heart attack. Ziltivekimab might reduce development of heart disease, thereby preventing new heart attacks or strokes. Participants will either get ziltivekimab (active medicine) or placebo (a dummy medicine which has no effect on the body). Which treatment participants get is decided by chance. The chance of getting ziltivekimab or placebo is the same. Ziltivekimab is not yet approved in any country or region in the world. It is a new medicine that doctors cannot prescribe. The study will last for about 2 years.
In this trial, the investigators aim to assess impact of goat milk-based infant formula on the severity and frequency of gastrointestinal symptoms, as well as other associated symptoms, and the health-related quality of life in infants exhibiting symptoms possibly related to cow's milk, compared to a cow milk-based formula.
During electrophysiological study (EPS) multiple drugs are used to reveal arrhythmias and/or conductive system disorders. Two most often used agents are atropine and isoprenaline. Due to their distinct pharmacological properties, they are affecting myocardium in different manner. Those dissimilarities can affect the EPS course and long-term prognosis. The aim of presented study is to evaluate the optimal protocol of pharmacotherapy during EPS.
The primary purpose of this study is to assess the antiviral activity of VH3739937 in Human Immunodeficiency Virus Type-1 (HIV-1) infected treatment naive (TN) participants during monotherapy.
Liver resection is the treatment of choice in patients with malignant liver lesions. Unfortunately, the surgery is not always an option, as in same patients the future remnant liver (FRL) is too small to supply all the functions. Therefore, some additional methods have been proposed to increase the size of the FRL. The aim of this study is to compare the efficacy and safety of three methods of increasing the future remnant liver - Portal Vein Embolization (PVE) - embolization of one of the portal branches; Liver Vein Deprivation (LVD) - embolization both of the portal branch as well as the hepatic vein; and partial ALPPS (Associating Liver Partition and Portal vein Ligation for Staged hepatectomy) - ligation of portal vein branch with partial liver transection. The efficacy of those three methods will be assessed both by analyzing the volumetric increase (by computer tomography scans) and by functional increase (by 99mTc-mebrofenin scintigraphy). Functional assessment of the liver hypertrophy seems to be of crucial importance, as some of the previous studies suggest that there might be a significant discrepancy in the increase of size comparing to the increase of function. This is a prospective, interventional randomized study. The study group (154 patients) will consist of patients being considered as candidates for major hepatic resection, after inducing hypertrophy of the future remnant liver. The primary study hypothesis is greater efficacy of ALPPS in preparing patients for large hepatic resection by inducing hypertrophy of the future remnant liver, as compared both to PVE and LVD. In case of unsuccessful induction of hypertrophy by the embolization techniques, patients may be qualified to rescue ALPPS procedure. Primary end-point: Percentage of patients with successful resection (patients, who gained sufficient increase of the FRL to proceed to the liver resection) with no post-surgical 90-day mortality. Secondary end-points: 1. the rate and degree of volume increase in different groups 2. the rate and degree of functional increase in different groups 3. CCI index and complication rate >=3 degree according to the Clavien-Dindo classification after the first stage of treatment 4. CCI index and complication rate >=3 degree according to the Clavien-Dindo classification after the second stage of treatment 5. overall duration of hospital stay Patient will be randomly assigned to the three study groups. All patients will undergo an abdominal contrast enhanced computed tomography and 99mTc-mebrofenin scintigraphy prior to the first stage of treatment. During the first stage of treatment, patients will undergo, according to their group: 1. Embolization of portal vein branch (PVE, portal vein embolization) 2. Embolization of both portal vein branch and hepatic vein (LVD, liver venous deprivation) 3. Partial ALPPS (Associating Liver Partition and Portal vein Ligation for Staged hepatectomy) - ligation of portal vein branch with partial liver transection, preferentially by laparoscopic technique Computed tomography scans and scintigraphy will be repeated at day 7, 14 and 21 after the first stage of treatment. The second stage of treatment, the liver resection, will be performed after achievement of sufficient mebrofenin clearance rate (>=2,69%/min/m2). In case of failure to reach the desired clearance rate, the measurements will be continued every 7 days up to day 42. In case of uncertainty and discrepancy between the volumetric assessment in the computed tomography scan and the mebrofenin scintigraphy, it will be allowed to proceed to stage two (partial hepatectomy) after joint consultation of at least 3 hepatobiliary surgeons, 1 radiologist and 1 nuclear medicine specialist. Routine blood tests will be performed according to the standard procedure in the Department, depending on the patient clinical status. An additional blood sample will be collected from patients (after receiving and additional informed consent from the patient) and will be stored in the biobank. All patients will be monitored for surgical and 90-day complications. The volume increase after first stage of treatment, the functional increase after first stage of treatment, percentage of patients successfully proceeding to the second stage of treatment and complication rate will be calculated. The percentage of patients with complications >= 3 degree in Clavien-Dindo classification and CCI index for each patient will be calculated. Furthermore, the blood test results will be assessed to search for associations with patients' outcomes. Any possible differences in terms of baseline patients characteristics between groups will be addressed. Statistical analysis will be performed using U Mann-Whitney test, exact Fisher's test, logistic regression, general linear models, Kaplan-Meier method and log-rank test. All three groups will be assessed in terms of occurrence of primary and secondary end-points.
