There are about 1129 clinical studies being (or have been) conducted in Estonia. 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 phase 3 clinical study is a randomized, observer-blind, multicenter study of QIVc versus a non-influenza vaccine in subjects 6 months though 47 months of age. The purpose of this study is to evaluate efficacy of QIVc in the prevention of Reverse transcription polymerase chain reaction (RT-PCR) confirmed influenza A or B disease in children 6 through 47 months of age, compared to a non-influenza vaccine.
A study to evaluate the long-term safety and tolerability of flexible doses of Lu AF11167 in patients with schizophrenia during the 24-week treatment period
The antidepressant medications are among the most commonly prescribed pharmacological agents in patients with mood and anxiety disorder. Despite recent advances in antidepressant pharmacotherapy, there is a pressing need for substantial optimization and improvment of outcome of pharmacotherapy of psychiatric disorders by providing individualized and science-based treatment guidelines. Besides it is rather difficult in clinical practice to predict, which patient will response to a certain pharmacological treatment well and which one less so. Putative predictors of response to antidepressant include demographic and clinical characteristics, personality traits, biological markers and psychophysiological features. Recently the research studies shown that divergences in antidepressant efficacy may be related to genetic variations of patients. The pharmacogenetic studies have multiplied in recent decade due to the impact that such studies may have in everyday clinical practice once reliable predictors could be identified. The pharmacogenetic research using new DNA microarray-based technology can reasonably be expected to contribute to the prediction of likelihood of treatment response and risk of development of adverse side effects in individual patients in case of antidepressant treatment. By reducing costly treatment failures and the likelihood of serious adverse events, pharmacogenetic testing may help to improve the treatment possibilities for chronic diseases, reduce the burden prescription drug costs, and lower the costs of drug development. The further detailed investigation of peripheral gene expression profiles may help to identify responsible genes that underlie the process of development of affective disorders and open novel horizons for understanding molecular mechanisms of psychopharmacological treatment.
The primary objective of this study is to evaluate the effect of filgotinib on semen parameters in adult males with active rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, or non-radiographic axial spondyloarthritis. Results of this study may be pooled with the results of a separate study being conducted in participants with inflammatory bowel disease (Protocol GS-US-418-4279; NCT03201445) with the same objective.
The pilot study collects the experience of previously successful treatment of infants, children and young adults, with ALL from a number of well-renowned study groups into a new platform protocol, which is both a comprehensive system for stratification and treatment of ALL in this age-group as well as the basis for several randomised trials included in the study-design. The pilot study is implemented as a master protocol without study specific interventions, thus as an observational study. The pilot study is for countries/study-groups who intend to join ALLTogether1 (including experimental interventions). For these countries the pilot study is crucial to optimise diagnostics, registration systems, collaborations with vendors, logistics and data-checks before starting the main study. The study only includes "standard of care" treatment included in the master protocol.
This study will provide information regarding the sequential administration of two vaccines adjuvanted with AS01. The aim of this study is to understand immunogenicity and safety of NTHi-Mcat vaccine when administered sequentially after Shingrix vaccine and to compare to the immunogenicity of NTHi-Mcat vaccine administered alone. This study will also provide information regarding whether a specific time period is required between the administration of these two different vaccines containing the same adjuvant- AS01 components. The population of this study will include healthy smokers and ex-smokers of 50 to 80 years of age which will be used as a proxy for the COPD population.
This is a Phase 2, multicenter, randomized, double-blind, parallel group, placebo-controlled study to investigate the safety, tolerability, efficacy and dose-response of GSK2831781 in participants with moderate to severe active ulcerative colitis. The study consists of a 5-week screening window, 10-week Induction Phase, 30-week double-blind Extended Treatment Phase (ETP) with 42-week Follow-Up Phase. Non-Responders identified following the Week 10 assessment will be allocated to open label treatment, consisting of Induction (Weeks 12 to 22), an Open label ETP (Weeks 22 to 42) and a follow-Up to Week 54.
Primary Objective: To determine the dose-response relationship for SAR442168 to reduce the number of new active brain lesions. Secondary Objectives: - To evaluate efficacy of SAR442168 on disease activity as assessed by imaging measures. - To evaluate the safety and tolerability of SAR442168.
This study will assess the effect of lowering low-density lipoprotein cholesterol (LDL-C) with evolocumab on major cardiovascular events in adults without a prior myocardial infarction (MI) or stroke who are at high risk of a cardiovascular event.
The main objective of the study is to evaluate the efficacy of dimethyl fumarate (Tecfidera) and peginterferon beta-1a (Plegridy), both compared with placebo, in pediatric participants with RRMS. The other objectives of this study are to evaluate the safety and tolerability of dimethyl fumarate and peginterferon beta-1a and to assess the effect of dimethyl fumarate and peginterferon beta-1a, both compared with placebo, on additional clinical and radiological measures of disease activity.
