There are about 1645 clinical studies being (or have been) conducted in Czech Republic. 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.
Aims and priorities of the project The purpose of this study is to 1. test the effect of frequency of meals (six vs. two meals daily with the same daily caloric restriction of -500 kcal/day) on insulin sensitivity, insulin secretion, and hepatic fat content. 2. characterize some of the mechanisms of action of different frequencies of meals (amount of visceral fat, hepatic fat content, serum concentrations of adipokines, gut hormones, oxidation stress markers). 3. test the ability of the participants to maintain hypocaloric diet on both regimens when educated and left to prepare their meals alone in comparison with those for whom all meals during the study will be provided. It will be a randomized, crossover study, where 50 individuals with type 2 diabetes will change in a random order two regimens: six, and two meals a day. Each testing period will take three months. Glucose and lipid metabolism and its regulation will be thoroughly tested at start, and after each 3-months-period (meal test, hyperinsulinemic isoglycemic clamp, indirect calorimetry, MRI scan of the liver, DXA scan, serum concentration determination of selected adipokines, gut hormones, and oxidation stress markers). Hypothesis The investigators hypothesize that low plasma insulin levels (as achieved by periods of fasting) will reduce insulin resistance and hepatic lipid content. In contrast, frequent meals (and consequent higher plasma levels of insulin) will predispose to non-alcoholic fatty liver disease and insulin resistance. The investigators further hypothesize that the participants will increase their caloric intake with increased meal frequency (in spite of thorough education) when left to prepare their meals in comparison with those for whom all meals will be provided.
The purpose of this study is to determine if there is an improvement in progression-free survival (length of time during and after treatment in which a patient is living with a disease that does not get worse) when siltuximab is added to VELCADE and dexamethasone in subjects with relapsed or refractory multiple myeloma.
Breast cancer is the leading type of cancer in women. Although big advance in diagnostics and treatment of early and breast cancer has been made in recent years breast cancer still has a significant mortality rate. A number of treatment modalities exist for postmenopausal women with advanced breast cancer. The treatment modality is chosen based on patient and tumour characteristics. Hormonal treatment is preferred and recommended in women with hormone sensitive breast cancer (ESMO, CECOG and NCCN guidelines). Tumor markers are an established method of monitoring systemic therapies in various cancers. Tumor markers CA 15-3 and CEA are used in clinical practice to monitor treatment efficacy of metastatic breast cancer. Blood levels of tumor markers are widely used to assess response/progression to treatment and guide therapy change. Treatment efficacy is assessed by imaging methods in clinical studies. Change of therapy in clinical study is usually done when progression based on RECIST criteria is found. Hormonal treatment has slower onset of effect compared with chemotherapy that can last several weeks. Also when a new therapy is started spurious early rises may occur. Therefore rising levels of tumor markers during the first weeks of new hormonal therapy are not necessarily sign of progression and should not be the only guidance for treatment change. Evidence of treatment efficacy form clinical studies and treatment change is based on imaging techniques.
The purpose of the study is to evaluate the improvements in signs and symptoms of rheumatoid arthritis (RA) for fostamatinib compared to placebo or adalimumab in patients who are Disease-Modifying anti-rheumatic drug (DMARD) naïve, DMARD intolerant or have had an inadequate response to DMARDs. The study will last for approximately six months
The present study has been designed in order to evaluate the efficacy and safety of two doses of Givinostat in subjects with polyarticular course JIA Givinostat ready-to-use suspension especially intended for paediatric administration, will be administered orally at different daily doses. Patients with an established diagnosis of one of the following JIA forms (Polyarticular JIA rheumatoid factor positive or negative, Oligoarticular extended JIA, Systemic JIA without active systemic features) will be enrolled. The treatment regimen will remain unchanged for 12 weeks and the clinical response will by assessed by applying the ACR Pediatric response criteria. Patients achieving at least an ACR Pediatric 30 response will continue receiving the assigned dose for 12 further weeks. After the end of study (week 24) responder patients will be allowed to extend the treatment until they maintain a clinical benefit.
This study was planned to provide new information regarding the role of aliskiren (with or without additional therapy with a diuretic or a Calcium channel blockers (CCB)) in elderly individuals (≥ 65 years) with systolic blood pressure (SBP) 130 to 159 mmHg, in preventing major cardiovascular (CV) events and on global measures of physical, executive and cognitive function.
Introduction: The aim of the study was to investigate the effectiveness of combined bipolar radiofrequency surgery of the tongue base (RFBT) and uvulopalatopharyngoplasty (UPPP) in a single session for obstructive sleep apnea (OSA) and to determine whether this combination is safe and well tolerated.
This is a two part study. During period one there will be a comparison of Etanercept (ETN) against a placebo with both arms maintaining the background anti inflammatory drug prescribed by their Physician. The hypothesis is that Etanercept will be superior to the placebo arm as determined by the proportion of subjects achieving Assessments in Ankylosing Spondylitis (ASAS)40 improvement at 12 weeks. This will be followed by 92 weeks extension where everyone in the trial receives Etanercept (ETN) and a background non steroidal anti inflammatory drug(NSAID).
The purpose of this study is to investigate the effect of AZD5069 in patients with bronchiectasis.
The purpose of this study is to allow patients similar to that evaluated in the TROPIC trial (NCT00417079), and Investigators access to cabazitaxel for the management of metastatic Hormone Refractory Prostate Cancer (mHRPC) in those patients who have progressed during or after docetaxel and to document the overall safety of cabazitaxel in these patients. Please note that in each country, patient recruitment will end when cabazitaxel becomes commercially available.
