There are about 2143 clinical studies being (or have been) conducted in Slovakia. 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.
The purpose of this study is to test the safety and efficacy of zanamivir given intravenously and how well it works at two different doses in hospitalized adolescents and adults with flu. Zanamivir will be compared with oseltamivir, which is used for treating flu.
This is a multicenter, phase III, randomized, subject and sponsor-blinded, placebo-controlled study to determine the treatment effect of "Anagrelide retard" in subjects with Essential Thrombocythaemia (ET) at "defined risk" (definition of risk criteria: see Inclusion Criteria Section 5.1) The study is planned as a 2-stage procedure according to Bauer and Köhne: After recruitment of 140 subjects an interim analysis with re-assessment of sample size is planned in an adaptive manner. As the confirmatory analysis will be based on a time-to-event evaluation (i.e. time to 1st clinically significant ET related event), there is no stipulated observation time identically applying for all subjects. Yet, with an interim analysis being performed after having recruited 140 subjects - which is expected to be reached after 1 year - the estimated observation time for a subject in stage I will also be about 1 year. (Details are explained in the section "Statistical Considerations"). Subjects will be randomized in a 1:1 ratio to one of the following two arms: Group A: Anagrelide retard Group B: Placebo An a priori stratification is planned for the JAK-2 mutational status. For exploratory purposes a post hoc stratification is used for obtaining covariate adjusted results, for the following other potentially predictive factors: sex, age, Factor V Leiden, and BMI. Dosing will be started with 1 tablet per day for week 1 and will be titrated up according to response (platelet reduction) to 2 tablets in week 2. Dosing may be further increased or decreased according to platelet response in week 3 and 4. However, the maximum dose is 4 tablets (=8mg) per day. After week 4, the maximum dose to achieve optimal platelet counts (<450 G/L) should be maintained (for visit schedule see study flow chart section IV). To verify a treatment response, platelet counts must be evaluated at every visit. The platelet count values will be withheld from the subjects for the duration of stage I or stage II respectively. The subjects have to agree explicitly to this procedure by signing the Informed Consent form. This is a patient and sponsor-blinded clinical study. The trial medical is packaged in the blinded fashion to keep the patient unaware (blinded) towards the actual treatment group they were randomized to. The sponsor functions (including medical monitor, pharmacovigilance manager, clinical project manager, trial data manager and trial statistician) with stay blinded in the course of the study until the database lock. Randomization scheme will be prepared by an independent statistician (not otherwise involved in the study), and will be stored securely with no access to it by the sponsor functions mentioned above. The process of randomization (provision of the individual drug-allocation information to the subjects) will be carried out by a trained staff by Harrison, in adherence to the procedures to keep the other blinded functions unaware of this information (blinded). Unblinding envelopes, which contain the treatment code per patient number for identification of treatment in case when a safety-relevant unblinding needed, will be stored at the sponsor's site. At the end of the study, verification of the extent of maintaining the blind by checking if the envelopes have been broken, will take place and will be properly documented. If the sealed envelope will broken to provide treatment identification, the date of breaking the code, the initials of the person who broke the code and the reason will be stated on the envelope. The operational details on the blinding procedures are outlined in the relevant working guidelines (ARETA Study Working Guideline for idv staff and ARETA Study Working Guideline for Harrison, each in its current version). Investigator will not be blinded in this study, i.e. in case of a medical need individual patient management will be driven by the full knowledge of the trial related interventions. For the case, the sponsor will need to unblind a patient (e.g. due to safety reasons), the above mentioned (in this section) envelopes will be used. Only treatment naïve subjects, in respect to cytoreductive drugs with confirmed diagnosis of ET (centralized re-evaluation according to WHO, 2008; see Section 6.2.1) and assessment of JAK-2 status (centralized re-evaluation of JAK-2 status; see Section 6.2.2) will be enrolled. As described above, stage I of the study will be considered as closed as soon as 140 subjects have been recruited. The duration of stage II depends on the result of the re-assessment of sample size. Once stage I is finished, stage I subjects will enter into an extension period for a maximum of three years.
This study aims to assess the safety, tolerability and Pharmacokinetics/ Pharmacodynamics (PK/PD) profile of three doses of MOD-4023 on a weekly regime and one dose on an every-other-week regime administered for a period of 4 weeks in Growth Hormone Deficient Adult (GHDA) patients who previously were on a stable r-hGH treatment. An additional extension period of 16 weeks once-weekly administration of MOD-4023 aims to confirm the dose selection for future trials.
This study is being carried out to see if a new drug called ticagrelor given twice daily in addition to the ASA therapy decreases the frequency of cardiovascular events (e.g., death from heart disease, heart attack, or stroke).
To assess the efficacy and safety of vildagliptin add-on therapy to reduce HbA1c in patients with T2DM inadequately controlled by insulin, with or without concurrent metformin therapy.
This study will evaluate the safety and efficacy of Dovitinib versus sorafenib in patients with metastatic renal cell cancer.
This study is conducted in Europe and Asia. The aim of this observational study is to monitor antibody formation towards the room temperature stable formulation of NovoSeven® (activated recombinant human factor VII).
This study is designed to evaluate the efficacy and safety of two different dosing regimens of 0.5 mg ranibizumab given as intravitreal injection in comparison to verteporfin PDT in patients with visual impairment due to choroidal neovascularization (CNV) secondary to pathologic myopia (PM).
This study is being carried out to see if dapagliflozin - administered in a daily dose of 2.5 mg given twice a day or 5 mg twice a day or 10mg once daily - in addition to metformin, is beneficial in diabetes treatment, and if so, how it compares to treatment with metformin alone.
In the light of ONTARGET and TRANSCEND studies results, it would be interesting to investigate the real-life telmisartan treatment tolerability. It is well known and accepted that the Real-life setting is much more adequate to reflect the antihypertensive and safety properties of the drug in comparison to the organized and scheduled setting of the clinical trial. Because there are not much data on the cough in relation to telmisartan, therefore it would we worth to observe the cough frequency and general treatment tolerance in patients treated with telmisartan, who had to stop their previous ACE-I treatment due to cough.
